description	Fix an existing creation that errored or delivered a wrong result. This applies to skills, apps, and services. Invoke at turn-end, after you worked around the failure to satisfy the user's request.

Healing a broken creation

This is the heal lead of the generic creation lifecycle. An existing creation should have delivered the correct result but did not; you dispatch a generic worker to reproduce the incident, find the root cause, apply a minimal fix, re-run scenarios, and present a single approval gate. Heal is a turn-end action -- do not interrupt in-flight work to invoke it; the user's original request is already delivered.

The type parameter

type is skill (the default), app, or service. The worker reads it and loads type-<TYPE>.md. (A system-interface regression is a heal operation too, but it is driven through update-system-interface, which owns the preview and the apply-or-roll-back go-live -- do not drive a system-interface heal from here.)

When NOT to heal

• The creation worked fine; the request was genuinely out of its scope -- that is an update-creation situation, not a heal.
• The failure was one-off and transient (network hiccup, rate limit).
• You are unsure why it failed. Finish the user's request, gather evidence, then decide if heal applies.

Conventions

Use $TARGET for the creation you are healing (e.g. migrate-config, an app or service name). Then:

• Worker agent name and branch: heal-$TARGET / mngr/heal-$TARGET
• Runtime dir / task file: data/.tasks/harden/heal-$TARGET/ / data/.tasks/harden/heal-$TARGET/task.md

Step 1: Open a tracking ticket

Single-flight check first. At most one harden pass per creation may be in flight (counting update passes on the same target). Run the pre-dispatch check in .agents/shared/references/harden-contention.md; if another agent's pass is live, leave the note it describes on their ticket and stop -- the superseding pass forced at their merge time covers your fix. Only dispatch if no pass is live (or you took over an abandoned one).

mkdir -p data/.tasks/harden/heal-$TARGET
TICKET_ID=$(tk create "heal $TARGET" -t bug \
    --acceptance "task file written; worker launched; worker DONE; branch merged")
tk start "$TICKET_ID"

Step 2: Write the task file

Frontmatter carries operation: heal, the type, and the worker reporting fields (per .agents/shared/references/worker-reporting.md). The body describes the failure and anchors the worker's search with verbatim quotes (the user's request, the failing command or error, any tool output that exposed the misbehavior). Without anchors the worker scans the wrong region of your transcript.

cat > data/.tasks/harden/heal-$TARGET/task.md << TASK_EOF
---
finish_report_path: data/.tasks/harden/heal-$TARGET/reports/report.md
operation: heal
type: skill
---

# Task: heal \`$TARGET\`

## Incident summary
<2-5 sentences: what the user asked for, how \`$TARGET\` was invoked, how it
failed, what you did to work around it.>

## Anchors (verbatim quotes)
The worker uses these with \`mngr transcript\` to locate the incident. Include
the user's request that invoked \`$TARGET\` (verbatim), the failing output /
exception / wrong result (verbatim), and any clarifying quote about expected
behavior.
<paste quotes here, one per bullet.>

## What the fixed creation must do
<the contract the healed creation must honor -- what input shapes should work,
what outputs are correct. Describe success; the incident itself is above.>

## What to do
Use the installed \`harden-worker\` sub-skill. It reads \`operation\` and
\`type\` from this frontmatter and follows the matching references:
reproduce the failure, find the root cause, apply a minimal fix, re-run 2-3
fresh scenarios, and push through the single final-creation gate. Push reports
to the lead per its reporting protocol.

## Success criteria
- The incident reproduces against the current creation before the fix.
- The fix addresses the root cause, not a symptom.
- The fresh scenarios pass after the fix.
- The user approved the final creation (via a pushed final-creation gate report).
TASK_EOF

Set type: as appropriate and fill in the real content; do not leave placeholders.

Step 3: Launch the worker and poll

Commit any pending changes before you launch, and never harden inline. The worker is created from your committed HEAD, so uncommitted changes never reach it -- and create_worker.py launch refuses a dirty tree outright. Commit your work first; commit, never stash -- stashed work gets lost during multi-agent coordination. A dirty tree (even unrelated changes) is never a reason to do the fix inline: commit, then dispatch. Healing always runs in the background worker.

uv run .agents/skills/launch-task/scripts/create_worker.py launch \
    --name heal-$TARGET \
    --template worker \
    --runtime-dir data/.tasks/harden/heal-$TARGET/ \
    --task-file data/.tasks/harden/heal-$TARGET/task.md

Then background-poll (create_worker.py await --task-file ... --timeout 90m, run_in_background: true) and follow .agents/shared/references/lead-proxy.md. Flow-specific substitutions:

• Worker name: heal-$TARGET; branch: mngr/heal-$TARGET
• Poll path: data/.tasks/harden/heal-$TARGET/reports/report.md; reports dir data/.tasks/harden/heal-$TARGET/reports/; consumed data/.tasks/harden/heal-$TARGET/reports/consumed/
• The only user-approval gate is final-creation -- a heal has no outline gate.
• Terminal statuses: done (go live, Step 4); stuck (failure flow per .agents/skills/launch-task/references/worker-failure.md).

Step 4: Merge and go live

On done, first run the merge-time checks in .agents/shared/references/harden-contention.md: wait out any foreground editing lease on the service, confirm the branch is still fresh (the creation's footprint has not changed since the worker branched), and never hand-resolve a conflicted merge -- a stale or conflicted pass is discarded and superseded by one new pass covering everything since the last hardened merge.

Then merge mngr/heal-$TARGET and go live by type: a skill needs nothing beyond the merge; an app wants a tab refresh (python3 system/scripts/layout.py refresh <app-name>); a background service has no tab -- restart it (supervisorctl restart <name>) instead. Then close the ticket:

tk close "$TICKET_ID" "Healed $TARGET -- worker branch merged."

Gotchas

• If the target is a built-in upstream skill, healing it causes local drift to reconcile later via update-self (pull) or submit-upstream-changes (push).
• Heal is non-blocking -- the user's original request is already delivered; the heal worker produces a quieter follow-up commit.
