When you need the person to choose between concrete options in a Clawdline Session, read `clawdline guide note` and create one answer Note with the question and complete suggested replies before asking in chat. Wait for the person's sent message before acting on the choice. For Codex's non-blocking request_user_input_async, also create one answer Note with the same question and complete replies so the person can return to it later. A blocking question prompt already waits for an answer and needs no duplicate Note. Never act on a suggested or preselected option before the person sends an answer.

## 9a. Leave a human intervention note

Use a note when a long-running Agent has one concrete thing the person should read, do, or decide and an ordinary chat message could disappear in the stream. The note remains in the target Session's collapsed attention area, marked with a red dot until the person moves it to handled. You may then continue independent work; the person can return at a natural stopping point. A note is not a progress log, a private reminder, or authorization for a Board decision. Avoid duplicate notes for the same request. Clawdline also sends a push for an agent-initiated note when notifications are enabled and a device is subscribed.

**Before asking the person to choose in chat**, create one `answer` note containing the actual question, the tradeoffs needed to decide, and two to four complete suggested replies. Tapping a button sends its reply as a conversation message, so make each `draft` unambiguous on its own. A brief chat pointer is enough after creation. Do not treat note creation or a note marked handled as the person's answer; wait for the conversation message — a tapped reply or one the person typed — before acting on it. If creation fails, say so and ask the question directly. Reserve notes for decisions needing human judgment, not routine choices the Agent can make. **Non-blocking questions remain available:** for Codex's `request_user_input_async`, also create one `answer` note with the same question and complete suggested replies. The person may answer from the transcript or return to the note later. A suggested or preselected option is not an answer; wait for the person's sent message. Blocking prompts, including Claude Code's `AskUserQuestion` and a blocking Codex question prompt, need no duplicate note.

Both Roots and live Clawdline children can create, list and withdraw their own Notes. A child still reports completion through its task result; Notes do not grant Board or to-do ownership. Create one with a JSON body file. Without `--target`, the CLI resolves this live Session's own terminal id through `whoami`. For another Session, use its live **terminal id** from the address book (`clawdline guide send`) as `--target`. `--from` defaults to this live Session's conversation id from the environment. The CLI reads the machine credential without putting it in the command line, injects the source and target ids, and prints the daemon's durable note id. Reuse the printed `--key` after an uncertain result.

```json
{"kind":"answer","title":"Choose a date","summary":"One release date needs your choice.","action":"Choose a date when you have a moment.","reason":"Only you can choose it.","options":[{"label":"Tuesday","draft":"Tuesday works for me."},{"label":"Wednesday","draft":"Wednesday works for me."}]}
```

```sh
clawdline note create --body-file note.json
# For another Session: clawdline note create --target <terminal-id> --body-file note.json
# Only when the person explicitly asked you to create this note:
clawdline note create --requested-by-person --body-file note.json
```

For a password, credential, or API key, use **Secret Handoff**. Create a `kind: "secret"` Note with a non-secret title, action and reason. Put the exact credential name (such as "Production API key") in `summary`; it appears as the label immediately above the dedicated multi-line field. Leave `detail`, `options`, and `document_url` empty. The person pastes the value into that field, even for a one-line value. Never request it in a suggested reply, normal message, document, or command argument. After the person submits, the target Session may run `clawdline secret run <note-id> -- <command> [args...]`; the command receives the one-time value on standard input, and its output is suppressed. The value expires in 15 minutes or on daemon restart. A failed consumer still consumes it. Ask for a new handoff when needed, and never print the value or pipe it through a shell transcript. See `docs/secret-handoff.md` for the boundary and person-facing steps.

`kind` is `read`, `answer`, `action`, `report`, or `secret`; `title`, `summary`, `action`, and `reason` are required. An `answer` can offer two to four choices. Each `draft` is the suggested reply shown on its button. When the person taps it, the Console sends it right away as a conversation message to the note's Session, followed by a context line with the note ID, title, and action so the receiving Session knows which request the person answered; the context is not shown on the button. Only after the send succeeds does the note move to recently handled. If the send fails, the note stays pending and the attention control says the reply was not sent. `detail` can hold longer text. `document_url` can link to a real, readable Cloud document; verify the document route and file before posting it. Act on the conversation message that arrives, not on the note's state: a note the person marked handled by hand sent nothing. Use `--requested-by-person` only for an explicit request to create the note, not for a broader request to complete work. That flag keeps the note visible without sending a note push. If your work is actually blocked on the answer, record the waiting-user state; an agent-initiated note already sends the attention push, so do not duplicate it. A note does not wake an Agent.

**Withdraw an obsolete Note**

Run `clawdline note list` to read only Notes attributed to your live Session (including their IDs, versions and current outcomes). When your own open Note no longer needs attention, run:

`clawdline note withdraw --id <note-id> --version <version> --reason "The prerequisite is now satisfied."`

The reason is required. Use `--from <live-session-conversation>` only when the environment cannot identify your Session. The CLI prints an idempotency key; reuse it with `--key` after an uncertain result. A stale version returns `version_conflict`: reread before deciding to retry. Another source's Note returns `intervention_not_found`; an already closed Note returns `intervention_already_closed` and preserves its outcome. Withdrawal removes the attention dot and moves the Note to recent history, in gray with its reason and an Agent-withdrawn label. It is never a person's answer or approval. The person can reopen it. Do not withdraw another Session's Notes or pretend a named source is cryptographically isolated: the machine credential remains shared.

# Clawdline

**This file is a pointer, not the guide.** The guide is compiled into the `clawdline` binary, so
the one you read is always the one written for the daemon that will answer you. Routes, fields and
refusals are deliberately not repeated here: a copy of them goes stale against the build.

## Load the guide first

Find the binary once, in this order, and use the first that exists:

1. `$CLAWDLINE_SKILL_READER`, if it is set.
2. `$CLAWDLINE_NEXT_DIR/bin/clawdline`, if `CLAWDLINE_NEXT_DIR` is set; otherwise
   `~/.config/clawdline-next/bin/clawdline` (`$XDG_CONFIG_HOME/clawdline-next/bin/clawdline` when
   `XDG_CONFIG_HOME` is set; `%APPDATA%\clawdline-next\bin\clawdline.exe` on Windows). The daemon
   keeps an up-to-date copy of itself there every time it starts.
3. `/Applications/Clawdline Next.app/Contents/MacOS/clawdline`, then the same under
   `~/Applications`.

Call it `BIN` below, and substitute the real path; do not run `BIN` literally.

```
BIN guide              # the core every session needs, and a list of the other parts
BIN guide dispatch     # one part, when the work in front of you needs it
BIN guide all          # the whole guide
BIN guide zh-Hant      # Taiwan Traditional Chinese; zh-TW remains an alias
BIN guide -sections    # the names of the parts
```

Reading the guide is a local read: it needs no running daemon and no network. **Read the core
before you run anything else**, then print a part when you reach work it covers — not the whole
guide up front: everything you read stays in your context and is re-read on every later call. Do not
guess routes or fields from memory, from an older guide, or from the Swift app's bundle — that
app's routes are not this daemon's.

If the path you chose exists and fails, report its exact error and stop. Do not fall through to the
next path: another binary may be a different build from the daemon that will answer you. If none
of the paths exists, Clawdline Next is not installed here; say so rather than inventing routes.

## Unify a Project's rules and skills

When invoked as `/clawdline unify`, or asked to make one Project's Claude and Codex sessions share
the same rules and skills, print `BIN guide project` and follow its **Unify** part exactly: show the
plan from `clawdline project unify`, apply it only after the person's message in this conversation
approves it, and never edit `AGENTS.md`, `CLAUDE.md` or a skill to resolve a conflict yourself.

## Roles

Which kind of work goes where is a boundary, not a routing detail; the guide names the route for
each.

- **Owned child**: a bounded task under this session, which keeps synthesis, integration and
  landing.
- **Handoff**: continuing or transferring an existing line of work, with its full state.
- **Detached automation**: unattended work with no root. Never a Root or a feature owner.
- **Root assignment**: a new, independently owned Root for a new feature. Never faked with a child,
  a detached task or a handoff.

A **Feature Root** — a Root assignment, or a Session given a Board item — prints `BIN guide
feature-root`: its whole ordinary path, from reading the item to done. It works in the owning
Session by default and dispatches only for a concrete need.

A Clawdline **child** does not dispatch and does not send a turn receipt; it reports through the
`result.json` its briefing describes.

   keeps an up-to-date copy of itself there every time it starts.

## Unify a Project's rules and skills

When invoked as `/clawdline unify`, or asked to make one Project's Claude and Codex sessions share
the same rules and skills, print `BIN guide project` and follow its **Unify** part exactly: show the
plan from `clawdline project unify`, apply it only after the person's message in this conversation
approves it, and never edit `AGENTS.md`, `CLAUDE.md` or a skill to resolve a conflict yourself.

## Roles

Which kind of work goes where is a boundary, not a routing detail; the guide names the route for
each.

- **Owned child**: a bounded task under this session, which keeps synthesis, integration and
  landing.
- **Handoff**: continuing or transferring an existing line of work, with its full state.
- **Detached automation**: unattended work with no root. Never a Root or a feature owner.
- **Root assignment**: a new, independently owned Root for a new feature. Never faked with a child,
  a detached task or a handoff.

A **Feature Root** — a Root assignment, or a Session given a Board item — prints `BIN guide
feature-root`: its whole ordinary path, from reading the item to done. It works in the owning
Session by default and dispatches only for a concrete need.

A Clawdline **child** does not dispatch and does not send a turn receipt; it reports through the
`result.json` its briefing describes.

• clawdline guide

• skills/sections.go:37
• skills/clawdline/guide.md:1
• skills/skills.go:25

## 1. Root or child

If your first message said *"You are a Clawdline CHILD agent for task …"*, you are a **child**. The
`CHILD.md` it names governs you: you do not dispatch, you do not send a turn receipt, you sign with
`clawdline task accept` and you finish with `clawdline task finish`. Stop reading here.

Otherwise you are a **root**: an ordinary session a person is talking to. The rest is for you.

If it said *"You are an independently owned Clawdline Feature Root …"*, or a Board item was assigned
to you, print `clawdline guide feature-root` next: it is the whole ordinary path from reading the
item to `done`, and it names the part to print for anything rarer.



## 2. Reaching the daemon

Read `clawdline guide routes` when you need to discover this build's registered route and the part that owns it. Compare the target machine's API level and available capability first. A listed route is not permission: read its owning part for the exact action, input, precondition, bound, typed refusal, retry rule, and receipt. Stop when the capability, version, identity, or completion evidence is missing. Do not use a retired helper, another machine, or a looser route as a fallback. Accepted, executed, delivered, observed, and acknowledged are different states; claim only the state the receipt proves. The human goal for each route is indexed beside it, and `docs/contract-model.md` defines the shared terms.

**Use the commands, not hand-built curl, where one exists.** They read the credential inside their
own process, so it never appears in a command line, in `ps`, in their output or in your
transcript. A hand-built curl without that credential answers `401 unauthorized` ("No valid
credential came with this request …"): it is the credential that is missing, not a permission. Run
the command instead.

| Command | What it does |
|---|---|
| `clawdline guide [lang]` | This guide. No daemon needed |
| `clawdline guide routes` | Registered route inventory for this build, API levels, owning parts, and human goals; no daemon needed |
| `clawdline session report --summary "…"` | Records your finished turn (§7) |
| `clawdline session close [--dry-run] [--terminal id]` | Audits and closes a finished Session, never by force (§2a) |
| `clawdline dispatch --title "…" --claims a,b < brief.md` | Dispatches an owned child (§4) |
| `clawdline item show\|steps\|name\|phase\|step-add\|step-done\|doc\|acceptance <item id> …` | Reads and advances a Board item you own (`clawdline guide feature-root`, §10) |
| `clawdline todo add\|list\|done` | This Session's own to-dos, only when the person asks (§10) |
| `clawdline heavy [--handoff] -- <command…>` | Queues application/native compilation; ordinary commands run directly; `--handoff` gives a queued wait to a callback (§11) |
| `clawdline send --to <terminal> "…"` | Relays a message into another session (§8) |
| `clawdline notify --title "…" --body "…"` | Pushes a notification to the person (§9) |
| `clawdline note create --body-file <JSON> [--target <terminal>]` | Leaves one actionable note above a Session (§9a) |
| `clawdline output add [--kind created\|modified\|published] <file>` | Registers one exact Session output path (§8) |
| `clawdline image send <picture>…` | Shows the person pictures under this Session's reply (§8) |
| `clawdline assistants` | What each assistant's account has left |
| `clawdline landings` | Every landing still owed on this machine; `--work-id <item id>`: every landing recorded for one Board item |
| `clawdline leases [--json]` | Who holds the compile slot and each landing lease, and who waits behind them |
| `clawdline sessions [--json]` | The Sessions a send, a wait or a handoff can name, with their state and task |
| `clawdline usage [--session <c> \| --task <id> \| --item <id>]` | What a session, child task or Board item spent, by category; yours by default |
| `clawdline cloud pair [--offer <code>]` | Pairs one Cloud browser with this machine |
| `clawdline cloud viewer login\|status\|machines\|pair` | Authorizes and pairs a separate local Cloud viewer |
| `clawdline cloud viewer sessions\|read\|send\|answer\|interrupt\|end\|receipt` | Uses an exact machine, Session, and execution generation through the local daemon |
| `clawdline task show [--json] <task id>` | One child task compactly: state, verdict, summary, leftover titles, verification, landing, checkout (§5) |
| `clawdline task wait <task id>… [--timeout 9m] [--any]` | Waits until the children finish (all, or `--any` one), shows each as `task show` does and closes its notice. Exit 0 all succeeded, 1 one failed, 5 one was cancelled and none failed, 3 timed out, 4 a task could not be read; 4 over 3 over 1 over 5 (§5) |
| `clawdline callback --title "…" [--timeout 30m] [--work-id <item>] -- <command…>` | Runs a long command — a deploy and its check, a wait on CI — under the daemon and returns at once; end your turn, and its exit types the same `<clawdline-notice>` a finished child's does (§5a, `clawdline guide callback`) |
| `clawdline task cancel <task id> --reason "…"` | Stops a child you dispatched by mistake: its tab is closed, its writes and slot are released, a branch with commits is kept for you (§5) |
| `clawdline task ack <task id> <notice id>` | Closes a completion notice by hand; rarely needed, since `task show` and `task wait` close it (§5) |
| `clawdline task accept <task dir>` | A child signing for its briefing. Roots never run it |
| `clawdline task finish <task dir>` | A child's completion. Roots never run it |
| `clawdline webhook fire [--url-file <path>] [--deliver-within 60s] [--timeout 60m] [--no-wait]` | Starts a schedule through its Cloud webhook, on any machine, and waits for its result; the exit code says how it ended ("Schedule future work"). No daemon needed |

With no explicit guide tag, CLI language follows `--lang <tag>` before the command, then
`CLAWDLINE_LANG`, saved `product_language`, and English. An explicit `clawdline guide <tag>`
overrides that choice; an unsupported tag shows English. `clawdline guide -list` names the nine
shipped tags. This preference changes human-readable CLI text, not protocol fields or an Agent's
language.

The orchestration commands above (not `webhook fire`) print the daemon's JSON on success; on a refusal they print
`refused, <status> <code>: <message>`, then each scalar the refusal carries as `key: value`, one per
line, and its remediation last, and exit 1. Cloud commands use their own human-readable
success and error output. `--port` overrides the port.

`clawdline usage` is the token ledger (`docs/token-ledger.md` in the repository): what each token was
spent on — `board`, `protocol`, `rules`, `impl`, `delegate`, `harness`, `talk`, `compaction`,
`other`. With no flag it reads your own session, named by `CLAUDE_CODE_SESSION_ID` or
`CODEX_THREAD_ID`. It prints one header line (calls, peak context, cost), one line per category by
cost — share, tokens, cost — and then every gap; `--json` prints the daemon's answer. `rules` is an
upper bound, and says so: a guard run in one shell command with other work takes that whole command.
The routes are `GET /v1/usage/sessions/<conversation>`, `GET /v1/usage/tasks/<task id>` and
`GET /v1/usage/items/<item id>`, read with a paired device or the orchestrator token. A session the
ledger has not read, or can no longer read, answers `not_yet_read`, `transcript_missing` or
`transcript_unreadable` — never an empty total; an id nobody knows is 404 `unknown_session`,
`unknown_task` or `unknown_item`. Whether the ledger is still reading is `usage` in
`/v1/diagnostics`.

**Continue on the completion notice.** After dispatching a child, end the turn: the child's own
completion notice wakes you, so do not add a callback to watch it. For a queued `heavy`, CI, deploy,
long build or other command that can run without Agent decisions, register `clawdline callback`
(or use `heavy --handoff` for native compilation) and end the turn. On its notice, run
`clawdline task show <id>` once; the read closes the notice. Treat success, failure and timeout as
different results. Inspect a failure, timeout or uncertain outcome before deciding whether a retry
is safe; do not start the same work again just because a wait expired. Do not poll from later turns,
including with `clawdline leases`. A token review counted 520 wait-only turns (72.2M tokens) over
ten items, mostly on queued `heavy` runs.
If an earlier `task wait` already printed the terminal result and closed the notice, a late notice
for that same task does not require another `task show` or another integration.

**Declare the callback's purpose.** `clawdline callback` defaults to `--intent wait` for a deploy
or an external result. Use `--intent heavy` when its command will run through `clawdline heavy`;
automatic `heavy --handoff` does this itself. The task record and `task show` expose the intent.
The Session list draws 🏗️ only while that heavy callback actually owns and runs in the compile
slot. A queued callback or one waiting for a result has no heavy marker.

**Show heavy work in the conversation.** Before starting `clawdline heavy`, make your last
person-facing sentence start with `🏗️` and name the work being started. If it hands off to a
callback (exit 76), end the turn with a short `🏗️` sentence saying what is queued and that the
completion notice will bring you back. For a wait callback, say what is awaited without that
heavy-work icon. Give no repeated waiting updates. If the handoff is refused or `heavy` exits 75,
say that the command did not start.

**A short wait inside the current turn.** Use this only when the result is needed to finish work
already in this turn and it is expected soon. Make one tool call with a long enough timeout; a
tool returning a session ID is still the same call when you collect it inside that cell. If the
wait times out, stop waiting and use the task's completion notice for the later result. Do not
start a second `task wait` or a sequence of status reads. `clawdline heavy` and a long test run
print nothing while running; for long commands use the callback path above.

- **Claude Code:** one Bash call with a long `timeout` (up to `600000` ms), or `run_in_background`
  and then nothing until its completion notification arrives. Not a loop of `sleep` and `tail`.
- **Codex (codex-cli 0.157.1, code mode):** put `// @exec: {"yield_time_ms": 600000}` on the
  first line of the `functions.exec` cell. After `exec_command` returns a session ID, await
  `write_stdin` with empty `chars` and `yield_time_ms: 300000`; if it still runs, repeat inside
  that same cell. Measured: the outer cell stayed open for 330 seconds with `600000`, while an
  empty `write_stdin` waited up to 300 seconds. If the outer cell yields, use `wait` with a long
  `yield_time_ms` to collect it.

  For a justified short in-turn wait, keep the session collection inside one
  cell so a normal 30-second `exec_command` return does not wake the Agent to
  issue the same wait again:

  ```js
  // @exec: {"yield_time_ms": 600000}
  let r = await tools.exec_command({cmd: "clawdline task wait --timeout 1m TASK_ID", yield_time_ms: 30000});
  while (r.session_id) {
    r = await tools.write_stdin({session_id: r.session_id, chars: "", yield_time_ms: 300000});
  }
  text(r.output);
  text(`exit ${r.exit_code}`);
  ```

  For a short build, replace the command with `tools/heavy.sh …` and retain its
  exit code: 75 means the compile-slot or memory wait expired before the build ran; 76 means `heavy --handoff` started a callback, so end your turn and wait for its notice.

`clawdline heavy` waits at most `--max-wait` (default 30m) and then exits 75 without running the
command. With `--handoff`, a queued wait starts a callback and exits 76; Ordinary `tools/check.sh` runs do not queue. A child needs no waiting callback. If a callback is refused, read the typed refusal and choose a supported path; a refusal has not started the command.

**Curl to an orchestrator route.** Read `<state dir>/orchestrator-token` and send it in the
`X-Clawdline-Orchestrator` header. Keep the token out of command arguments: use
`DIR="${CLAWDLINE_NEXT_DIR:-$HOME/.config/clawdline-next}"`, then
`-H @<(printf 'X-Clawdline-Orchestrator: %s\n' "$(cat "$DIR/orchestrator-token")")`.
Use `curl --fail-with-body`; every POST with a JSON body also needs
`-H 'Content-Type: application/json'` (otherwise `415 unsupported_media_type`).



## 7. Report your own finished turn

When your turn is genuinely finished — the work done, verified and committed where that applies —
make this your last action before the final answer:

```sh
clawdline session report --summary "One concrete sentence about what was delivered."
```

It draws one check on your session's row: **delivered, awaiting approval**. It is weaker than a
landing and asks for no review. It shows while the daemon reads the session as idle — working,
waiting or an unreadable screen outrank it — and only while that terminal holds the same
conversation.

- **Only for a finished turn.** Not for partial work, a diagnosis, a blocker or a question back to
  the person. A child never sends it (`409 child_session`).
- The command finds your conversation from `CLAUDE_CODE_SESSION_ID` or `CODEX_THREAD_ID`
  (`--conversation` otherwise), asks `GET /v1/orchestrator/whoami` for the terminal, and posts
  `{"summary"}` to `POST /v1/orchestrator/sessions/<terminal>/complete`.
- The summary is 1–500 characters. Each call is a new receipt; the newest counts.
- The answer also carries `open_todos`: this Session's direct to-dos that were sent or read and are
  not completed, oldest first, at most 20 (`open_todos_truncated` when there are more). The command
  prints them on stderr after the receipt, one id and text per line. Check off each one you
  finished with `clawdline todo done <id>`. The receipt is recorded either way and the exit status
  does not change; `open_todos_unknown: true` means they could not be read, not that none are open.
- Refusals: `conversation_id_malformed` (not a lowercase UUID), `conversation_not_found`,
  `conversation_ambiguous`, `registry_stale`, `session_not_found`, `session_unbound`,
  `child_session`. Report the refusal honestly; a sentence in chat is not a receipt.

**Register deliverables before reporting.** The header's Output files button shows
native successful writes and explicitly published paths. Shell-created deliverables
must be registered with `clawdline output add <file>` (see §8); do not infer their
ownership from a directory scan. Register only this Session's actual outputs,
not input attachments, secrets, caches or another Session's work.

**Leave a status report for the person.** When the turn changed files in a git project, hand the
person one page where they can see where the work stands and read every file the turn added or
changed. It is a local HTML file: nothing is uploaded, and it loads nothing.

```sh
clawdline report --repo <project> --status status.md [--notes notes.txt] [--lang zh-TW] [--open] <commit>…
```

- Name **this turn's own commits, oldest first**. Each is read on its own, so another Session's
  commits between them stay out; never pass a range.
- `status.md`: an optional `# Title`, an optional line under it, then one `## ` heading per card —
  open it with ✅, 🟡 or ❌ — and a short Markdown body.
- `--notes`: one `path: sentence` per line, shown above that file. `--pin` (repeatable) puts a file
  first; `CLAUDE.md` and `AGENTS.md` are pinned when the turn touched them. `--exclude` leaves a
  path out and says so. `--at` is the revision whose contents are shown (default `HEAD`).
- It keeps the report in `<state dir>/reports/<date>-<id>/report.html`, outside every repository,
  and prints two addresses: **first the `file://` address**, which a terminal opens, **then
  `http://127.0.0.1:<port>/reports/<id>`**, which this machine's daemon answers. Put both in your
  final answer: the console shows a `file://` address as text it cannot open, and makes the
  `http://` one a link. That address opens only in a browser on this machine that is signed in to
  its console; a phone or a Cloud viewer is refused (`report_not_over_cloud`,
  `report_local_only`).
- `--out` writes another file or directory instead, with the `file://` address only. stderr says
  what it left out or shortened. `--open` also opens the file in this machine's browser.



## 9. Tell the person

```sh
clawdline notify --title "At most 80 characters" --body "At most 500 characters"
```

`POST /v1/orchestrator/notify`. Only for something the person is waiting on: the value of a push is
that it is rare. `--session <terminal>` makes a tap open that session.

- `409 agent_notify_disabled`: the person turned agent notifications off. Not your fault; do not
  retry.
- `409 not_subscribed`: no device is subscribed to pushes.
- `429 rate_limited`: 30 an hour for the whole machine, shared with every child's notifications.
- `502 push_failed`: the push service refused; `sent` and `failed` are in the error.



## 9a. Leave a human intervention note

Use a note when a long-running Agent has one concrete thing the person should read, do, or decide and an ordinary chat message could disappear in the stream. The note remains in the target Session's collapsed attention area, marked with a red dot until the person moves it to handled. You may then continue independent work; the person can return at a natural stopping point. A note is not a progress log, a private reminder, or authorization for a Board decision. Avoid duplicate notes for the same request. Clawdline also sends a push for an agent-initiated note when notifications are enabled and a device is subscribed.

**Before asking the person to choose in chat**, create one `answer` note containing the actual question, the tradeoffs needed to decide, and two to four complete suggested replies. Tapping a button sends its reply as a conversation message, so make each `draft` unambiguous on its own. A brief chat pointer is enough after creation. Do not treat note creation or a note marked handled as the person's answer; wait for the conversation message — a tapped reply or one the person typed — before acting on it. If creation fails, say so and ask the question directly. Reserve notes for decisions needing human judgment, not routine choices the Agent can make. **Non-blocking questions remain available:** for Codex's `request_user_input_async`, also create one `answer` note with the same question and complete suggested replies. The person may answer from the transcript or return to the note later. A suggested or preselected option is not an answer; wait for the person's sent message. Blocking prompts, including Claude Code's `AskUserQuestion` and a blocking Codex question prompt, need no duplicate note.

Both Roots and live Clawdline children can create, list and withdraw their own Notes. A child still reports completion through its task result; Notes do not grant Board or to-do ownership. Create one with a JSON body file. Without `--target`, the CLI resolves this live Session's own terminal id through `whoami`. For another Session, use its live **terminal id** from the address book (`clawdline guide send`) as `--target`. `--from` defaults to this live Session's conversation id from the environment. The CLI reads the machine credential without putting it in the command line, injects the source and target ids, and prints the daemon's durable note id. Reuse the printed `--key` after an uncertain result.

```json
{"kind":"answer","title":"Choose a date","summary":"One release date needs your choice.","action":"Choose a date when you have a moment.","reason":"Only you can choose it.","options":[{"label":"Tuesday","draft":"Tuesday works for me."},{"label":"Wednesday","draft":"Wednesday works for me."}]}
```

```sh
clawdline note create --body-file note.json
# For another Session: clawdline note create --target <terminal-id> --body-file note.json
# Only when the person explicitly asked you to create this note:
clawdline note create --requested-by-person --body-file note.json
```

For a password, credential, or API key, use **Secret Handoff**. Create a `kind: "secret"` Note with a non-secret title, action and reason. Put the exact credential name (such as "Production API key") in `summary`; it appears as the label immediately above the dedicated multi-line field. Leave `detail`, `options`, and `document_url` empty. The person pastes the value into that field, even for a one-line value. Never request it in a suggested reply, normal message, document, or command argument. After the person submits, the target Session may run `clawdline secret run <note-id> -- <command> [args...]`; the command receives the one-time value on standard input, and its output is suppressed. The value expires in 15 minutes or on daemon restart. A failed consumer still consumes it. Ask for a new handoff when needed, and never print the value or pipe it through a shell transcript. See `docs/secret-handoff.md` for the boundary and person-facing steps.

`kind` is `read`, `answer`, `action`, `report`, or `secret`; `title`, `summary`, `action`, and `reason` are required. An `answer` can offer two to four choices. Each `draft` is the suggested reply shown on its button. When the person taps it, the Console sends it right away as a conversation message to the note's Session, followed by a context line with the note ID, title, and action so the receiving Session knows which request the person answered; the context is not shown on the button. Only after the send succeeds does the note move to recently handled. If the send fails, the note stays pending and the attention control says the reply was not sent. `detail` can hold longer text. `document_url` can link to a real, readable Cloud document; verify the document route and file before posting it. Act on the conversation message that arrives, not on the note's state: a note the person marked handled by hand sent nothing. Use `--requested-by-person` only for an explicit request to create the note, not for a broader request to complete work. That flag keeps the note visible without sending a note push. If your work is actually blocked on the answer, record the waiting-user state; an agent-initiated note already sends the attention push, so do not duplicate it. A note does not wake an Agent.

**Withdraw an obsolete Note**

Run `clawdline note list` to read only Notes attributed to your live Session (including their IDs, versions and current outcomes). When your own open Note no longer needs attention, run:

`clawdline note withdraw --id <note-id> --version <version> --reason "The prerequisite is now satisfied."`

The reason is required. Use `--from <live-session-conversation>` only when the environment cannot identify your Session. The CLI prints an idempotency key; reuse it with `--key` after an uncertain result. A stale version returns `version_conflict`: reread before deciding to retry. Another source's Note returns `intervention_not_found`; an already closed Note returns `intervention_already_closed` and preserves its outcome. Withdrawal removes the attention dot and moves the Note to recent history, in gray with its reason and an Agent-withdrawn label. It is never a person's answer or approval. The person can reopen it. Do not withdraw another Session's Notes or pretend a named source is cryptographically isolated: the machine credential remains shared.



## 12. What to do when something is refused

- Branch on `error.code` (or `error` in the flat shape). The message is for people.
- `retry_after` means it is a capacity answer: wait that long, then send the same request.
- `409 stale_write`, `503 orchestrator_store_busy`: the store was busy; the same request again is
  safe.
- `unknown` anywhere — an ownership, a liveness, a source — means the daemon could not read it. It
  is not "absent", and nothing should be deleted or declared dead on it.
- If a route you expected answers `404 not_found` or `501`, it is not in this daemon. Say so; do not
  fall back to the Swift app's routes or to provider-native subagents in its place.

## 2a. A Feature Root's ordinary path

This is everything an ordinary Feature Root — a Session that owns one Board item — runs, in order.
Every step is a command: the commands carry the credential, and a hand-built curl to the same route
is refused. Anything rarer is one `clawdline guide <part>` away; the pointers are at the end.

**1. Read the item.** `clawdline item show <item id>` prints its kind, phase, acceptance criteria,
captured gates, the acceptance version (`acceptance vN`), for a Feature the person's Needs
independent review switch, its steps, full description, every document with its body, and the
reference-image inventory. For each image, follow the printed `clawdline item image <item id>
<image id> --output <new file>` command, then open that file with your image-reading tool before
planning. The command saves the full pixels and refuses a missing or unreadable image. An item
with no images says so explicitly; an omitted image inventory is an error, not an empty list.
`clawdline item show <item id> --doc <doc id>` prints one document's body alone, to pipe into a
file; `clawdline item steps <item id>` is the shorter record without the bodies. Every item
write prints `wrote …; item <id> is at version N`, a short item summary, and an `item show`
hint. Read the full acceptance, description, steps, documents, and images with `item show`. Writes act on the item's current version unless you pass
`--expected-version`.

If your ASSIGNMENT.md has a **HANDOFF** heading, you are taking over an item another Session left
mid-flight (reassigned after implementing began, before done). Read the pack it names
first, before planning. The daemon built it from its own records and git, without asking the
previous owner: the tasks bound to the item and their results, commits not yet landed, each
worktree's uncommitted changes saved as a patch with its sha256 and the `git apply` command that
restores it on its base, the previous owner's last message (or why it could not be read), and the
phase and open steps. The patches live beside ASSIGNMENT.md and outlast the worktrees. Continue
from there; do not start over.

**2. Name your Session**, if it was opened for this item:
`clawdline item name <item id> "<task name>"`, once, after reading the objective and scope. It renames the Session, not the item.

**3. Before implementing.**

- Captured planning on and no acceptance criteria: write observable ones with
  `clawdline item acceptance <item id> --body-file acceptance.md`.
- Needs independent review checked, or an Epic: the reviewed-plan path in `clawdline guide epic`
  comes first. Unchecked: no plan, no review child.
- Multi-stage work with no steps: `clawdline item step-add <item id> "first" "second" …` (two to
  eight steps you can verify one at a time; a single change takes none).
- Then `clawdline item phase <item id> implementing`.

**4. Work in this Session by default.** Investigate, implement, verify and land the Feature
yourself. Dispatch only when a concrete need makes a separate Session useful: genuinely independent
parallel work, different tools or permissions, or required independent review. Say why before
dispatching; a routine investigation or implementation alone is not a reason.

When dispatch is needed, keep synthesis, integration and landing here:

```sh
clawdline dispatch --title "…" --claims a.go,b.go --isolation worktree --work-id <item id> < brief.md
```

- `--work-id` binds the child to the item, so its landing counts as the item's. Repeat it when one
  child does several items: the first is the child's line, and the landing counts for every one.
- The title is one line of at most 60 characters saying what will be different. Any colon (`:` or
  `：`) is refused, because it joins an observation to an explanation; so is "the user" as the
  subject, or a title opening with a code-formatted identifier. Each answers `bad_task` with
  `title: …` saying which.
- The brief stands on its own. Put in it the facts you have already verified, each with its
  `file:line` or the command that showed it, so the child does not rediscover them.
- An investigation or Explore child's brief also states its stop condition — the question that,
  once answered, ends the task — and a turn limit.
- Read-only work is `--claims ""`. Every flag, and every refusal code, is in
  `clawdline guide dispatch`.

**5. If a child finishes**, a `<clawdline-notice>` line is typed into your composer. Run
`clawdline task show <task id>`, then integrate the delivery; reading it closes the notice, so there
is no separate ACK. **After a dispatch, end your turn**: the notice wakes you, and a turn kept open
to wait rereads your whole context on every poll. Only when the result is needed to finish this
turn and expected soon may you use one bounded `clawdline task wait <task id>…`; after its timeout,
end the turn and let the native notice wake you. Never create a waiting callback for that child.
Integrate a worktree child by **merging its branch** into the target. **The merge records the
landing by itself** within a few minutes: do not post a landing by hand. `clawdline landings` lists
what is still owed. A child dispatched with `--claims ""` that wrote nothing is recorded
`nothing_to_land` by the broker. Anything else is `clawdline task land <task id> <state>`
(`clawdline guide landing`).

**6. Completion report**, when finding the cause took substantial investigation (a direct,
observed fix needs none). Add it before `done`: once the item is done it is unassigned, and the
report answers `409 not_item_owner`.

```sh
clawdline item doc <item id> --role completion_report --title "Completion report" --body-file report.md
```

Write it for the person who reported the problem, in Markdown, with no private data.

**7. Finish the item.** Complete each step once it is verified with
`clawdline item step-done <item id> <step id>`. Commit and push direct work from a disposable
worktree; merge a child's branch when one was used. Once landed, one command takes the item to
`done`. A child's recorded landing supplies commit, target and remote; direct work names them:

```sh
clawdline item finish <item id> --verification "what was run and what it showed" \
  --commit <sha> --target main --remote origin \
  --deployment "what went live, where, which version"      # omit landing flags for a landed child
```

Or advance one phase at a time:

```sh
clawdline item phase <item id> deploying        # a landed --work-id child is the evidence
clawdline item phase <item id> deploying --commit <sha> --target main --remote origin   # otherwise; push first
clawdline item phase <item id> deploying --no-landing-reason "why there is no code"    # work with no code
clawdline item phase <item id> done --deployment "what went live, where, which version"
clawdline item phase <item id> done --no-deployment-reason "why nothing needs deploying"
```

`done` takes `--deployment` or `--no-deployment-reason` as the item's deployment policy says. When
`clawdline item steps <item id>` prints a gate line, this item keeps the longer path that line
points to.

**Waiting on a deploy.** Do not keep the turn open while a deploy runs or propagates. Start the
deploy and its check as one callback, end the turn, and finish the item when its notice arrives:

```sh
clawdline callback --title "The hosted console serves <sha>" --work-id <item id> --timeout 20m -- \
  sh -c './deploy.sh <sha> && tools/wait-hosted-console.sh <sha>'
# … the notice: clawdline task show <callback id>, then
clawdline item finish <item id> … --deployment "what went live, where, which version (callback <callback id>)"
```

**8. Report the turn**: `clawdline session report --summary "…"` (§7).

**9. Leave the owning Session open.** Completing or cancelling a Board item releases its assignment;
it does not end the Session that owned it. After `session report`, leave the Session available for
follow-up work. Do not run `clawdline session close` merely because the item reached `done` or
`cancelled`. A person may explicitly ask to close the Session later. The broker separately closes
an agent-dispatched child's tab after that child's task ends, under the child-tab rule in
`clawdline guide child`.

**When something is refused.** `version_conflict`: run the same command again; it rereads the
version. `steps_incomplete`: a step is still open. Any other code: §12, then the part that covers
it.

**Rarer work, one part each:** `clawdline guide board` — proposals, decisions, to-dos, reopening a
done item, waiting on the person, gates and every phase refusal; `clawdline guide epic` — plans,
plan review, an Epic's child items, personas; `clawdline guide landing` — landing by hand,
handoffs (a long Root's milestone handoff too), Root assignments; `clawdline guide running` — stalled children, leftovers, respawn.

const machineInstructions = `# Clawdfather machine workspace

This directory is managed by Clawdline and is outside every Project. Work here as a machine steward: inspect and report on Sessions, tasks, waits and landings with source and observation time; use Clawdline's supported setting and project import/export operations when authorized.

For Session resource coordination, read ` + "`clawdline guide coordination`" + ` and ` + "`docs/session-resource-coordination.md`" + ` in the Clawdline Project. Order operations from current, sourced observations. Ask a Session to reach a safe point with ` + "`clawdline coordination pause`" + `; only its ` + "`coordination safe`" + ` receipt means paused. Wake it with ` + "`coordination wake`" + ` after its condition holds. Use the existing leases, waits and callbacks; do not poll from a parked model turn or kill an important command.

Do not edit source code in any Project, including Clawdline. When the person requests engineering work through Clawdline, create a Board item in the target Project first, then delegate it to a Project Session with ` + "`clawdline item add --project <id> --kind feature --title <title> --assign-new`" + `. The created item's owner handles implementation, child dispatch, verification, landing and deployment. If the person has not explicitly asked for an item, file a proposal for them to accept; do not create an item or dispatch code work on your own. Never dispatch a code task directly from this machine Session or mark another owner's work complete. This directory is an organizational boundary, not an operating system sandbox.

Opening this Session does not register the machine role. After your conversation ID is available, run ` + "`clawdline coordinator bind`" + ` in this Session. If the command is not on PATH, use the daemon's installed binary at ` + "`../bin/clawdline`" + ` from this workspace (` + "`../bin/clawdline.exe`" + ` on Windows). The command uses this conversation ID and rebinds an older role only if it is proven offline. Read ` + "`clawdline guide coordination`" + ` for the receipt and limits. Do not treat an unknown reading as offline.

## 7. Report your own finished turn

When your turn is genuinely finished — the work done, verified and committed where that applies —
make this your last action before the final answer:

```sh
clawdline session report --summary "One concrete sentence about what was delivered."
```

It draws one check on your session's row: **delivered, awaiting approval**. It is weaker than a
landing and asks for no review. It shows while the daemon reads the session as idle — working,
waiting or an unreadable screen outrank it — and only while that terminal holds the same
conversation.

- **Only for a finished turn.** Not for partial work, a diagnosis, a blocker or a question back to
  the person. A child never sends it (`409 child_session`).
- The command finds your conversation from `CLAUDE_CODE_SESSION_ID`, `CODEX_THREAD_ID`,
  or the daemon-published `CLAWDLINE_PROTOCOL_SESSION_FILE` for an owned Gemini conversation
  (`--conversation` otherwise), asks `GET /v1/orchestrator/whoami` for the terminal, and posts
  `{"summary"}` to `POST /v1/orchestrator/sessions/<terminal>/complete`.
- The summary is 1–500 characters. Legacy calls without a key create a new receipt; the newest counts.
- For a large Git delivery, use `clawdline session report --summary "…" --evidence-file <JSON>`.
  The UTF-8 document (at most 256 KiB and 4,096 full commit IDs) binds the exact summary to a
  passed Git delivery check and the SHA-256 digests of its baseline and ownership manifest.
  See `docs/session-delivery.md` for the version 1 schema and responsibility boundary.
  The full original document and its SHA-256 are stored with `session.delivered`; the answer
  includes `delivery_evidence_sha256` and `delivery_evidence_commits`. No commit goes in the
  summary unless it helps the reader. Evidence is an authenticated adapter assertion, not
  independent review, landing, deployment, or permission to publish.
- Evidence calls require an `Idempotency-Key`; the CLI derives a stable key from the exact
  document, terminal and conversation. Retry the same document and identity to replay the
  original answer without another receipt or push. Changed bytes use a different key.
  An older daemon refuses the extra field; do not fall back to a summary-only report.
  `delivery_evidence_invalid`, `delivery_evidence_mismatch`, `delivery_evidence_unverified`,
  and `delivery_evidence_too_large` create no receipt. A missing/mismatched acknowledgement is
  `delivery_evidence_ack_unknown`, not success. `request_outcome_unknown` after a daemon crash
  is not retried under a new key; inspect the stored event before deciding what to do.
- The answer also carries `open_todos`: this Session's direct to-dos that were sent or read and are
  not completed, oldest first, at most 20 (`open_todos_truncated` when there are more). The command
  prints them on stderr after the receipt, one id and text per line. Check off each one you
  finished with `clawdline todo done <id>`. The receipt is recorded either way and the exit status
  does not change; `open_todos_unknown: true` means they could not be read, not that none are open.
- Refusals: `conversation_id_malformed` (not a lowercase UUID), `conversation_not_found`,
  `conversation_ambiguous`, `registry_stale`, `session_not_found`, `session_unbound`,
  `child_session`. Report the refusal honestly; a sentence in chat is not a receipt.

**Register deliverables before reporting.** The header's Output files button shows
native successful writes and explicitly published paths. Shell-created deliverables
must be registered with `clawdline output add <file>` (see §8); do not infer their
ownership from a directory scan. Register only this Session's actual outputs,
not input attachments, secrets, caches or another Session's work.

**Leave a status report for the person.** When the turn changed files in a git project, hand the
person one page where they can see where the work stands and read every file the turn added or
changed. It is a local HTML file: nothing is uploaded, and it loads nothing.

```sh
clawdline report --repo <project> --status status.md [--notes notes.txt] [--lang zh-TW] [--open] <commit>…
```

- Name **this turn's own commits, oldest first**. Each is read on its own, so another Session's
  commits between them stay out; never pass a range.
- `status.md`: an optional `# Title`, an optional line under it, then one `## ` heading per card —
  open it with ✅, 🟡 or ❌ — and a short Markdown body.
- `--notes`: one `path: sentence` per line, shown above that file. `--pin` (repeatable) puts a file
  first; `CLAUDE.md` and `AGENTS.md` are pinned when the turn touched them. `--exclude` leaves a
  path out and says so. `--at` is the revision whose contents are shown (default `HEAD`).
- It keeps the report in `<state dir>/reports/<date>-<id>/report.html`, outside every repository,
  and prints two addresses: **first the `file://` address**, which a terminal opens, **then
  `http://127.0.0.1:<port>/reports/<id>`**, which this machine's daemon answers. Put both in your
  final answer: the console shows a `file://` address as text it cannot open, and makes the
  `http://` one a link. That address opens only in a browser on this machine that is signed in to
  its console; a phone or a Cloud viewer is refused (`report_not_over_cloud`,
  `report_local_only`).
- `--out` writes another file or directory instead, with the `file://` address only. stderr says
  what it left out or shortened. `--open` also opens the file in this machine's browser.

Run a zero-based review of this Project. Create an Epic to track it, then assign independent reviews from the relevant roles: product, UX, architecture, code quality, efficiency, documentation, and evidence.
Require evidence for every finding. Compare the current design with mature expert practice, and distinguish deliberate trade-offs from accumulated complexity.
Find confusing behavior, redundant steps or reads and writes, and missing capabilities.
Synthesize a report and a target process. Turn improvements into role-owned child items, and list decisions that need my input separately.
Collect shared facts once and include them in each review brief so reviewers do not repeat the same reading.

# Poteto workflow for Clawdline

This is Clawdline's bundled adaptation of pstack 0.15.36, pinned to cursor/plugins c742dd61706fbacc1b95f1a20b7b988cf096ce6c. It is not the complete Cursor plugin. Its routing and verification practices run with Clawdline's existing tools. No remote skill, dependency installation, model routing, hook, PR stack, or autonomous publishing is required.

The current request, repository rules, task boundaries, permissions and existing checks remain authoritative. This workflow grants no permission to spend, contact others, delegate, restart, deploy, delete data, force-push or bypass a guard. Ask for authorization only when the governing rules require it. Never infer authorization from a workflow name.

## Route the task

Start with the person's desired outcome and the smallest useful change. Determine whether this is an investigation, bug fix, feature, refactoring or evaluation. Investigations stop at a supported answer; they do not manufacture implementation work. A bug fix starts by reproducing the observed failure on the affected surface. A feature starts with the data shape and externally observable acceptance criteria. A refactoring preserves behavior. An evaluation defines the common task, controls and measurements before comparing results.

## Work in verifiable units

Identify the data owned by each boundary before changing code. Prefer a small, direct structure with explicit state over extra layers. For a real design uncertainty, inspect the repository or build a bounded local prototype. Product preference and authorization decisions still belong to the person.

Divide substantial work into independently checkable units. Each unit names its inputs, output and acceptance evidence. Keep a short checkpoint of what is proved, what remains uncertain and the next verification. Combine stages for small changes; do not impose an elaborate ceremony on a one-line edit.

Delegate only independent, bounded work when the current authorization and repository rules allow it. Give each worker the goal, exact write scope, starting revision, required tools and acceptance criteria. Use the existing Clawdline child/worktree/claims protocol where required; inherit the task's frozen workflow. Review the returned changes yourself. Do not invent Cursor agents, unavailable control skills or different-model calls.

## Verify the delivered behavior

For a defect, show that the reproducer fails before the fix and passes afterward. For a feature, make a verification map from each acceptance criterion to a test, real UI observation, artifact inspection or explicitly pending human judgment. Verify the actual surface: UI behavior in a browser, CLI behavior through its entry point, and deployment only at its authorized destination. Compilation alone does not establish behavior.

Tests should exercise observable behavior rather than source spelling. Use the smallest relevant checks while editing and the repository's required commit gate before committing. Do not broaden testing repeatedly without a new failure or unresolved concern. Respect the repository's landing and release policy; pstack's stack shipping commands are not part of this adaptation.

## Deliver evidence

Report the change, exact revision, checks actually executed, failures or unknowns, and remaining work. Distinguish an instruction added to a launch, an agent reporting it followed the workflow, and independently verified results. No report proves causal benefit merely because it mentions this workflow. Preserve rerunnable evidence for measured claims. State the request count and cost for separately authorized paid API work; this workflow never authorizes it.

If a repeated defect reveals a missing structural guard, propose or implement the smallest appropriate guard within scope and verify that it rejects the defect. Keep user-facing prose plain and specific. Never claim an unavailable tool ran or that a successful check proves an untested destination.
