Github Issue Closeout Race Safe

GitHub issue closeout race-safe pattern

Use when:

• closing issues after verification or implementation
• multiple agents/terminals may act on the same issue
• the closeout comment is important evidence and must not be lost

Problem

gh issue close --comment "..." is convenient, but in live multi-agent use the comment can be lost if the issue becomes closed before the command lands cleanly.

Safe pattern

1. Post the evidence comment first.
2. Close the issue as a separate command.

gh issue comment <issue> --body-file /tmp/closeout.md
gh issue close <issue>

Why this works

• The closeout evidence becomes durable even if a separate process closes the issue moments later.
• It avoids silent loss of the most important verification/implementation summary.

Recommended closeout block

Include:

• Result: landed / already done / blocked
• Evidence checked
• Validation commands/results
• Commit hashes or artifact paths
• Residual risks or blockers

Extra verification

After commenting/closing, verify:

gh issue view <issue> --json state,comments,url

Confirm:

• issue state is CLOSED when intended
• the closeout comment is present in recent comments

Tool-budget guardrail

When closeout is part of a larger implementation/verification turn, do not leave evidence comments and issue closure until after optional cleanup, extra review polish, or broad worktree hygiene. Once the deliverable is committed/pushed and the closeout evidence is known, post the evidence comment immediately, then close as a separate command. This prevents tool-call or context limits from leaving an otherwise-complete issue open with no durable closeout trail.

If additional verification is still desirable after closeout, state it as residual follow-up in the comment rather than delaying the comment itself.

For the concrete pattern, including how to verify a push that reports a transient GitHub remote cannot lock ref race even though origin/main advanced to the intended SHA, see references/tool-budget-and-remote-ref-race-closeout.md.

When not necessary

If you intentionally want a single quick close with no meaningful evidence, gh issue close alone is fine. But when evidence matters, always comment first, then close.
