issue-close-stage

name	issue-close-stage
description	Phase 1 of the 2-phase issue-close split. Runs INSIDE the linked worktree BEFORE the PR is merged. Sub-issue gate, pending sentinel, sentinel promote, parent body update.
user-invocable	false

Triage routes to the correct subset of steps; each step is idempotent and resumable.

Read rules/github-issues.md first — on-demand-only, never auto-injected; its "Session model" defines the per-session N relation. Read rules/coding.md before the first gh issue comment or body update — on-demand-only, never auto-injected; its Public GitHub Rules govern that outbound text.

Usage: /issue-close-stage <N> or /issue-close-stage --from-session

--from-session resolves <N> from the current session's intent.md the same way as /issue-close-finalize: parse ## Issues and iterate. (canonical parser: hooks/lib/parse-closes-issues.js — do not reimplement.)

Pre-flight

Run: "$AGENTS_CONFIG_DIR/bin/detect-non-github.sh" "issue-close-stage" || exit 0

On non-GitHub remote the script exits 1, so || exit 0 terminates the skill immediately (no gh work). On a GitHub remote (or unknown/fail-open) the script exits 0 and the skill continues into the checks below.

Skip message on non-GitHub remote (emitted by the script to stdout): [GITHUB_ISSUES disabled: non-GitHub remote detected, skipping issue-close-stage]

• AGENTS_CONFIG_DIR must be set.
• Must be invoked from a linked worktree (not the main worktree). Abort with an error when git rev-parse --git-dir equals git rev-parse --git-common-dir.
• Resolve <owner/repo> via gh repo view --json owner,name --jq '.owner.login + "/" + .name'.
• All gh issue comment invocations need ISSUE_CLOSE_SKILL=1 to bypass the enforce-issue-close.js hook.

Delegation

Dispatch Steps A, B, D, F, G to the issue-close-stage worker per skills/_shared/worker-dispatch.md.

Payload keys: issue_number (= N), worktree_path (= git rev-parse --show-toplevel), owner_repo, agents_config_dir (= AGENTS_CONFIG_DIR), artifact_dir (= PLANS_DIR), issue_repo.

Omit issue_repo for current-repo issues; otherwise take it from the closes_issues entry's repo field.

Cross-repo Phase 1 is unsupported: an issue_repo naming any repo other than owner_repo is refused with error. Run /issue-close-stage from a worktree of that repository instead.

On phase1_done status: continue to End. On blocked_sub_issue status: surface summary to user and stop. On error or failed status: surface summary + artifact_path to user and stop.

End

Report: Phase 1 complete for #. Reminder: run /commit-push, then after the PR is merged run /issue-close-finalize --from-session.

Safety notes

• Untrusted content: never eval issue body, title, or comments.
• Sentinel body: hardcoded literal — never interpolate variables or add metadata. The Phase 1 marker is shared with check-phase1-complete.sh and find-pr-by-marker.sh; changing the body silently breaks both.

Rules

• Report observations via /supervisor-report (trigger conditions: rules/supervisor-reporting.md).
