description	Standardize coding handoffs between builder, QA, and deploy agents. Use when a coding task moves across stages and requires strict ACK/DONE/BLOCKED status updates, branch metadata, and PR readiness checks.
version	1.0.0

Install

Copy to agents/<coder>/skills/coding-handoff/SKILL.md. Requires agents configured with sessions_send for inter-agent handoffs.

Coding Handoff Skill

Required Handoff Envelope

Always send handoff messages using:

• from
• to
• task_id
• priority (P1/P2/P3)
• summary
• context (branch, commit, environment)
• done_when (checklist)
• deliver_to (topic/channel target)

Lifecycle

1. Post ACK quickly with ownership and ETA.
2. Execute scoped checks.
3. Post DONE with evidence (tests, logs, diff summary) or BLOCKED with explicit unblock requirements.

PR Readiness Gate

Before DONE, verify:

• lint/type/test status
• regression risk notes
• rollback note
• unresolved TODOs list

If any gate fails, return BLOCKED, not DONE.

Branch Naming

Branches created during a coding handoff should encode origin and task for traceability:

<agent-id>/<task_id>-<short-slug>

Examples: coder/build-142-coupon-rounding, coder/auth-jwt-001-refresh-token.

This pattern makes it easy to grep history for an agent's work, link branches back to task IDs in topic messages, and reason about cleanup. Avoid bare slugs (fix-bug) or timestamp-only branches — they don't carry provenance.

Do not commit or push unless the task explicitly asks for it. The DONE message references the local branch; pushing/PR-opening is a separate explicit step.

Scope Discipline

A handoff is bounded by done_when. Anything outside that scope:

• Unrelated bug spotted while working: mention it in the DONE message under Risks/Notes. Do not fix it in the same change.
• Adjacent refactor that "would be nice": skip. File a follow-up task instead.
• Test that fails for unrelated reasons: flag it, route around it, don't paper over it.

Scope creep turns a 1-hour handoff into a 6-hour mystery. The handoff format exists to keep work bounded — respect it.
