dispatch	Turn "start a session in repo X, on order Y, at cost Z" into a complete, verified startup command — the prompt written to a file, the model and effort derived from the rubric, and the output form chosen by whether the target repo already has a terminal pane. Use whenever work is being handed to a session in another repo, or to this repo's own next session: "dispatch a session in repo X", "start a session there with this order", "give me the startup command for repo Y", "hand this work to <repo>", "write the plan file for that session", "open a tab for X with this task", "how do I launch the next session on this". Also triggers on Norwegian phrasings: "dispatch en økt i repo X", "start en økt der med denne ordren", "gi meg oppstartskommandoen for Y", "send arbeidet til <repo>", "skriv planfila for den økten", "åpne en tab for X med denne oppgaven", "hvordan starter jeg neste økt på dette". Also covers the background form, where the dispatching session starts the child itself with `claude --bg`: "start it in the background", "run that as a background session", "launch a bg session on this order", "start en bakgrunnsøkt i repo X", "kjør det i bakgrunnen", "start barnet selv". Trigger even when no tool is named — producing a runnable startup command for another session IS this skill. Not for choosing WHICH repo deserves the next session (that is `board`), not for scoring model and effort alone (that is `route`), and not for sending a message to another repo (that is `coord-send`).	0.35.0

dispatch — hand a session a task it can actually start on

A dispatch is one line the operator pastes and one file that line reads. Both halves are easy to get wrong in ways that look right: a command with no prompt in it, a plan file the driver silently discards, a --no-go that does not stop what everyone assumed it stopped. All three were measured on 2026-08-16 — four separate misfires in one day, by two different repos — and this skill exists so they are not re-derived a fifth time.

In the paste and plan-file forms you produce the command and never run it. Starting a session in another repo spends the operator's quota and takes an action inside a repo this session does not own. Hand back the finished command and stop. The one exception is the background form (its own section below): since the operator's decision of 2026-09-22 the PM starts sessions itself with claude --bg, and that form is run, not handed over.

The engine

ORDER="${CLAUDE_PLUGIN_ROOT}/scripts/coord-order-send.sh"
BOARD="${CLAUDE_PLUGIN_ROOT}/scripts/board.sh"

"$ORDER" --to <name> --subject "<one line>" --prompt-file <absolute path>

"$BOARD" --dispatch --repo <name> \
         --order-id <the id the order engine printed> \
         --target-pane <yes|no> \
         --path <known|partial|undetermined> \
         --verification <strong|weak|none> \
         --reversibility <cheap|costly|one-way> \
         --scope <local|multi-file|cross-cutting> \
         --rationale "why these four scores"

It writes nothing and prints one block. Exit 2 means it refused — read stderr and fix the call; every refusal is a case where a command would have been wrong rather than merely imperfect.

It is board.sh and not a script of its own because the block format (tab=/repo=/dir=/command=/paste=) has exactly one generator. Two emitters of one file format is the drift defect this repo's CLAUDE.md warns about.

The five steps, in order

1. Write the prompt file

The order goes in a file, in plain prose:

mkdir -p "$HOME/.claude/dispatch"
PF="$HOME/.claude/dispatch/<repo>-$(date -u +%Y%m%dT%H%M%SZ).prompt"

Write the whole order: the concrete task, which discipline applies (Iron Law, TDD, which file the test goes in), and what must not be triggered. A prompt that says only "continue" forces the receiving session to guess its task out of STATE.md, which is the thing handing over a prompt is supposed to prevent.

Norwegian prose, æøå, quotes, $ and backticks are all fine in the file. That is measured, not assumed: the order body never passes through a shell.

2. Deliver it into the recipient's order queue

"$ORDER" --to <repo> --subject "<one line naming the task>" --prompt-file "$PF"

It prints order-id=<id>. That id is the whole handle from here on.

This step is what makes a dispatch survive the pane it was typed into. The prompt file is scratch: it carries the order to one session and nothing records it afterwards. Measured 2026-08-17: an order was dispatched three times over 90 minutes before it was worked, because the first two tabs ran something else and the order left no trace anyone could find. In the queue it stays pending, is re-injected at every session start in that repo, shows up in board's ORDRE column, and is closed only by a session that claims and finishes it.

The queue is ~/.claude/coord/<repo>/orders/ — the same private local infrastructure as the mailbox, and a different channel from it. Mail is untrusted cross-repo data that can never instruct a session; an order is operator-authorized work. Never send an order as a coord-send message and never send a message as an order.

--to refuses what coord-send refuses: _-prefixed names, path traversal, and the retired ktg-plugin-marketplace address (send to catalog).

3. Measure whether the target already has a pane

morning --probe-panes | grep "<absolute dir of the target repo>"

A hit means --target-pane yes. Measure it; never assume it. This is the one input --dispatch refuses to default, for the same reason route.sh refuses to default --last-effort: it is a fact about the world, and guessing it produces a dispatch that verifies green and opens nothing.

Two facts about this measurement, both verified 2026-08-16 against the installed morning:

• --probe-panes works from a Claude session, without a tty. It cannot identify the anchor pane, but the DIR column — the part you need — is there.
• A session dispatching its own next session is always --target-pane yes. That is not a special case for one repo; it is what self-dispatch is, and it is where all four of the day's misfires landed.

4. Score the four traits and call --dispatch

Scoring is judgement and it is yours; the model and effort are a lookup and are route.sh's. Score the task the dispatched session will do, using the route skill's trait table.

Pass --order-id <id>, not --prompt-file. The emitted command is then a thin starter: it carries no order text at all, only the id and the four steps the receiving session runs (claim, compare against STATE's NESTE, execute, close). The order text has exactly one home, and a copy in argv would be free to drift from it and would die with the pane. --dispatch refuses an --order-id that is not in the target's pending queue — the same rule as the empty prompt file, one level up.

--prompt-file still works and is the fallback when there is genuinely no queue to write to. Passing both is refused: the session would be told two things.

--dispatch deliberately takes no --model/--effort. The rubric is a policy with exactly one copy, and a dispatch that took the model directly would be a second, unscored way to reach the same decision — one that records no traits, no rationale and no next-cost, so nothing afterwards could say whether the routing or the scoring was wrong. Score the traits and let the lookup spell the command. If the right call is a Fable row, the rubric cannot produce it: write that command by hand and say in the handover that it is a recorded override.

No --advisor is emitted, by the rubric or by this skill. That rule was struck 2026-09-12 on a measurement — 0 of 54 dispatches carried the flag. The advisor is an operator decision per session; do not add one to a dispatch command.

5. Verify, then hand it over

--target-pane no (plan-file form). Write the whole output to a file and dry-run it:

"$BOARD" --dispatch ... > "$HOME/.claude/dispatch/<repo>-<ts>.plan"
morning --plan-file "$HOME/.claude/dispatch/<repo>-<ts>.plan" --dry-run

Expect opening: 1 of 1. Then hand back:

morning --plan-file <path to the plan file> --no-go

Know what that dry-run does not prove. It proves the block parses and yields a command. It does not answer the pane question: run from a Claude session there is no tty, so morning reports window: unknown ... assuming an empty window and plan_drop_open never fires. A gate built on the dry-run would pass the self-dispatch case every single time — the one case it would exist to catch. Step 2 is the measurement; this is a parse check.

--target-pane yes (paste-only form). There is no plan file, deliberately: morning's plan_drop_open (morning:1788) drops a block whose repo already has a pane. Hand back the paste= line, and say it goes in the existing tab after /exit. Never prefix it with cd — one repo per terminal tab, and the operator is already standing in that one. morning --relaunch bypasses the filter but opens a second tab beside the existing one, which is rarely wanted.

The background form

When: the PM starts the child session itself (operator decision 2026-09-22, ~/.claude/docs/2026-09-22-tos-bakgrunnsoekter-og-natt.md). Not when the operator is to paste a line into a tab. That is still steps 3–5 above. The background form replaces steps 3–5 only. Steps 1–2 are unchanged: the order goes into the recipient's queue first, and the id is the handle. There is no pane question, because a background session has no pane.

The command, run by the dispatching session through its Bash tool:

cd <absolute repo dir> && claude --model <m> --effort <e> --disallowedTools AskUserQuestion,SendMessage,ListAgents --bg --name <short-name> "<starter>"

• --model directly after claude, always. ~/.claude/hooks/pre-dispatch-budget.sh counts a start only in that position. Measured 2026-09-22: claude --model … --bg --name x is counted, but a flag with a value in front of --model breaks the pattern and the start goes uncounted. The form must not depend on the hook learning more forms. Take the model and effort from route.sh's command= line (score the traits as in step 4). That line already begins claude --model <m> --effort <e>, so appending the rest keeps the order by construction. A Fable override is written by hand, in the same order.
• --disallowedTools AskUserQuestion,SendMessage,ListAgents (hardening T4, ~/.claude/docs/2026-09-22-herding-s1-steg4.md § 3). A background child cannot be answered. AskUserQuestion was open and stopped two sessions before this guard existed. SendMessage/ListAgents close the child→PM direction. The PM's own messages to the child are still delivered.
• The cd is right here, and only here. The no-cd rule is for a line pasted into a terminal tab, where the operator already stands in the repo. This line is run by a session standing in another repo, and claude --bg starts in the working directory, so the cd is what picks the repo.
• --name: a short name (<repo>-<topic>), so claude agents and claude logs <id> can be read at a glance.

The starter is one line of ASCII, with no $, backtick or double quote. It sits inside the double quotes above and is evaluated by the shell, exactly like board.sh's thin starter. <PLUGIN_ROOT> is the absolute install directory the engine lines at the top of this skill resolve to (the parent of dirname "$ORDER", e.g. the version-pinned plugin cache). Write it out in full, because a child executes the starter literally and the order verbs are not on PATH (ORDRE 65).

ORDRE <id> ligger i dette repoets ordrekoe. Gjor dette i rekkefolge: (1) claim den - bash <PLUGIN_ROOT>/scripts/coord-order-claim.sh <id> - claim skriver ut hele ordreteksten. FULL STI ER MED VILJE. Claim KUN denne ordren. (2) Sammenlign mot STATE.md NESTE og uttal avviket i ditt FORSTE svar. (3) Du er en bakgrunnsoekt isolert i en NY worktree: sett grenen din til <hash> (git checkout -B <gren> <hash>) og verifiser. Commit paa den grenen, ingen fletting, INGEN push/tag/release - operatoren pusher. Du kan ikke stille spoersmaal; ved et teknisk valg, ta det anbefalte og skriv valgt X fordi Y. Lange kjoringer i forgrunnen, aldri arm venter. (4) Lukk med bash <PLUGIN_ROOT>/scripts/coord-order-done.sh <id> --commit HASH - eller --return --reason. Rapport som coord til <sender> via coord-send.

• Claim KUN denne ordren stays in even when the queue holds only this one. Another order can land between the dispatch and the child's first turn.
• <hash> is the commit the child must build on, not automatically main. If the repo tracks STATE.md/PLAN.md and the newest of those commits sits on a branch that has not been merged, the hash is that branch's tip. Measured wrong 2026-09-23: d5a6bac was given where 8bd27d8 was meant.
• INGEN push/tag/release: the child commits on its branch and stops. The operator's push round merges, pushes, and runs release-plugin.mjs.

Measured platform facts (agent-view docs + 2026-09-22): a background session is forced into its own worktree. It cannot write in the main checkout, not even after ExitWorktree. It never merges. That is why the starter pins the branch and forbids the merge rather than asking for either.

What happens afterwards, and it is the PM's:

1. Watch the order, not the process. The child's claim moves the order to ~/.claude/coord/<repo>/orders/claimed/<id>.md. Closing moves it to orders/archive/<id>.md (executed), or back to orders/<id>.md (returned, with the reason written into it). claude agents / claude logs <id> show the session. The file shows whether the work reached a terminal state.
2. Re-measure on the commit. Read the commit= the child wrote into the archived order. Then run that repo's suites at that hash yourself. The child's report is a claim, not a measurement.
3. The merge is the operator's. The branch waits for the operator's push round, which merges, pushes and releases. A background child never does any of the three.

Why this is not a board.sh rendering. board.sh --dispatch is the one generator of the plan-block format (tab=/dir=/command=/paste=), and this form uses none of it. There is no block, no pane and no morning consumer. The one generated part, model and effort, already has its single generator in route.sh. So --target-pane stays exactly yes|no, and the selftest pins that. Stated overlap: steps (1), (2) and (4) of the starter repeat the protocol in board.sh's thin starter. If the protocol changes, both copies must move together.

Three things that must reach the operator

Say these in the handover, not only in the plan file. Each was a real correction, not a hypothetical:

1. The command carries the prompt in argv. claude --model X --effort Y on its own is not a dispatch; it is a session waiting for someone to tell it what to do. Delivered bare twice on 2026-08-16, corrected by the operator with "gi meg alltid komplette oppstartskommandoer for nye sesjoner".
2. --no-go does not make the session wait. It suppresses only the follow-up Go message — morning:806 is exact: "--no-go says nothing is typed once the startup command is in". The startup command, prompt and all, is typed regardless, so the dispatched session starts working on its own. An operator decision was once taken on the opposite premise and had to be corrected before the run.
3. Which form you produced, and why. "Plan file, because <repo> has no pane" or "paste line, because <repo> already has one and a plan block for it would be dropped". The form is a consequence of a measurement, and the operator should be able to see the measurement.

What happens at the far end

The dispatched session claims the order and owns it until it closes it:

coord-order-claim <id>                       # atomic; exactly one session wins
coord-order-done <id> --commit <hash>        # executed, with a result pointer
coord-order-done <id> --no-commit --reason "<why>"
coord-order-done <id> --return --reason "<why>"   # back to the queue, with the reason

The claim prints the order and tells that session to compare it against its own STATE.md NESTE block and to state any divergence in its first reply. That is the point of the D-check: a dispatch that displaces a live next step is a decision, and it should be an uttered one rather than a silent one.

If the tab is never run, nothing is lost. The order sits pending, the next session in that repo sees it at startup, and board counts it in ORDRE.

Where a dispatch is still not enough

An order is a task. When what the other repo needs is a notice — something is fixed, a premise changed, a question needs answering — that is coord-send, not a dispatch. The test is whether you are asking for work to be done (order) or telling them something they must decide what to do with (mail).
