Workbench Capy Git Dialogue Guardrails

Use this skill when implementing, reviewing, or dogfooding the Capy Git Dialogue Responder, especially for SYN-31, GitHub webhook responder work, Capy-authored PR/comment loops, or any task that could let Capy write back to a GitHub, Linear, or Slack surface.

This skill is source-layer only. It does not deploy Capy, enable webhooks, write Linear, post Slack, or mutate live OAuth/runtime state.

Read First

1. DECISIONS.md entry 2026-05-06 - Add Self-Loop Guardrails To The Capy Git Dialogue Responder
2. docs/capy-git-dialogue-responder.md
3. .capy/CAPTAIN.md, .capy/BUILD.md, and .capy/REVIEW.md when checking a repo-local Capy pack
4. autopilots/capy-linear-slack-sync.md only when Linear/Slack sync is in scope

Required Gate

Before any write-capable action, compute this block from source evidence:

CAPY_GIT_DIALOGUE_GUARDRAIL
event_author:
actor_classification:
human_request_present:
last_capy_commit_sha:
last_capy_comment_ids:
mutation_allowed:
circuit_breaker_state:
action_taken:
verdict: PASS | FLAG | BLOCK

Use the local dogfood helper for bounded fixture checks:

node scripts/capy-git-dialogue-guardrail.mjs --format json <event-summary.json>
node scripts/test-capy-git-dialogue-guardrail.mjs

Mutation Rules

• Capy-authored comments, review comments, reviews, closeouts, commits, and synchronize events are observation only unless a human explicitly asks Capy to continue in that exact thread or after that exact commit.
• The automatic patch budget is one patch attempt per PR per distinct human-authored review-finding batch.
• Commit/comment/review churn from Capy itself is FLAG plus operator approval, not another patch loop.
• Duplicate closeout for the same repo, PR, head SHA, and verdict tuple is a no-op.
• Webhook receipt is not proof of repo state; verify PR, check, review, and git state from primary evidence.

Verdicts

• PASS: mutation is allowed by a current human request and the patch budget is still available, or the action is read-only observation.
• FLAG: mutation is refused because the trigger is self-authored, the patch budget is exhausted, or Capy churn requires operator approval.
• BLOCK: the event summary is malformed or primary source identity cannot be established.

Do not claim live rollout. Source-layer PASS only means the guardrail source and dogfood fixtures passed.
