Join

Intent

Run a continuous PR operator using gh commands only. Keep PRs created, green, and merge-ready with minimal-incision fixes. Do not approve or merge PRs unless explicitly instructed by the user.

Command boundary (hard rule)

• Use only gh CLI commands (gh pr, gh run, gh api, gh repo).
• Do not run git or any non-gh command.
• If a required action cannot be completed with gh alone, apply auto:hold and leave a blocking comment.

Quick start

1. Ensure gh auth status succeeds.
2. Ensure labels exist: auto:manage, auto:hold.
3. Start the monitor loop.

Auth preflight (required)

• Run these checks before any PR routing or mutation:
  • gh auth status
  • gh repo view <owner>/<repo> --json nameWithOwner --jq .nameWithOwner
• If either check fails:
  • Fail fast for the current run.
  • Apply auto:hold on affected PRs (or emit hold outcome in cloud loop when no PR is selected yet).
  • Record reason as auth_unavailable.

Label contract

• auto:manage: opt-in to automation.
• auto:hold: pause automation.

Contributor guidance:

• Add auto:manage to opt in.
• Add auto:hold to stop the operator.

PR creation policy (gh-only)

• For every non-default branch discoverable via gh api without an open PR, create a PR.
• Use the repo PR template if present; else use assets/pr-template.md.
• Prefer gh pr create --fill and apply auto:manage.
• Default to ready-for-review (no drafts unless configured).

Operating mode

Use one mode only:

• gh-only remote mode: no local checkout assumptions and no local workspace mutations.

Cloud Join operator ($puff + seq -> join)

Use this when running Join as a cloud subagent loop:

1. Launch with $puff join-operator.
2. For each patch artifact, route by weighted manifest-first scoring (include PR file-path hydration via gh pr view <num> --json files): target_pr_hint (+5.0), touched_entities overlap (+0..4.5), changed_paths overlap (+0..3.0), base-branch match (+1.5), and issue_refs (+0.5 each, max +1.0). Compute confidence as min(0.99, (raw_score / 12.0) * risk_multiplier) where risk_multiplier={low:1.00, medium:0.95, high:0.80, critical:0.65}.
3. If routing gates fail, run $seq first to recover intent/context. Routing gates are: confidence below effective threshold (threshold * risk_threshold_multiplier where risk_threshold_multiplier={low:0.95, medium:1.00, high:1.15, critical:1.25}), top-two score margin < 0.75, no entity/path/hint signal, manifest entities exist but no entity match, or risk_level is high|critical.
4. Then run $join for gh-only PR operations and CI/handoff behavior.

Launch recipe:

• "$PUFF_SCRIPT" join-operator --env <env-id-or-label> --repo <owner/repo> --patch-inbox <locator>
• Canary recipe (one bounded cycle):
  • "$PUFF_SCRIPT" join-operator --env <env-id-or-label> --repo <owner/repo> --patch-inbox <locator> --canary

Cloud auth note:

• In cloud environments, provide GH_TOKEN (or GITHUB_TOKEN) with repo-scoped permissions needed for join operations.

Patch manifest contract

Patch producers should emit a manifest that validates against:

• assets/cloud-join-manifest.schema.json
• assets/cloud-join-manifest.example.minimal.json (copy-ready minimal example)
• assets/cloud-join-manifest.example.full.json (copy-ready full example)

Required fields:

• patch_id
• producer
• repo (owner/repo)
• base_branch
• changed_paths (non-empty)
• intent_summary

Optional routing hints:

• target_pr_hint
• issue_refs
• touched_entities (array of objects with entity; optional file and kind)
• risk_level (low|medium|high|critical)
• confidence
• patch_file

Monitor loop

Process PRs sequentially (blocking per PR on CI):

1. List open PRs: gh pr list --state open --json number,title,headRefName,labels,isDraft.
2. For each PR:
   • Skip if auto:hold.
   • Skip if not auto:manage and not agent-created.
   • If draft, mark ready: gh pr ready <num>.
   • Keep the branch current with gh pr update-branch <num> --rebase when available.
   • Enforce CI gate (required checks only; see below).
   • If failing, run the surgical fix loop.
   • When green, publish merge-ready handoff status.
   • Do not approve or merge.

CI gate (required checks only)

• Gate on required checks only (gh pr checks --required). Optional checks do not block handoff.
• Detect “ungated” repos/PRs (no required checks):
  • If gh pr checks <num> --required --json name returns an empty list, treat CI as green and proceed to handoff.
• Wait for required checks (blocking):
  • gh pr checks <num> --required --watch --fail-fast
  • This blocks until all required checks pass or the first required check fails.
• Stalled CI (10 minutes with no observable progress):
  • Define “progress” as any change in the required-check snapshot (name, bucket, startedAt, completedAt).
  • While waiting, periodically sample: gh pr checks <num> --required --json name,bucket,startedAt,completedAt.
  • If the snapshot does not change for 10 minutes while not all checks are bucket=pass, apply auto:hold and leave a summary comment with links to the stuck checks.
  • Treat bucket=pending, bucket=skipping, and bucket=cancel as “not green” (blocked) until resolved; do not mark as handoff-ready through them.
• Drill into GitHub Actions when needed:
  • Identify check links: gh pr checks <num> --required --json name,bucket,link,workflow
  • Find likely runs: gh run list --branch <headRefName> --limit 10
  • Watch a run live: gh run watch <run-id> --compact --exit-status
  • Fetch failing step logs: gh run view <run-id> --log-failed

Surgical fix loop (gh-only)

Smallest change that makes CI green using gh only:

1. Read the failure from CI logs.
2. Apply the minimal fix through GitHub APIs via gh api on the PR head branch.
3. Re-run checks and re-evaluate.
4. Apply a hard regression floor before each new attempt:
   • Snapshot required checks before and after each attempt (gh pr checks <num> --required --json name,bucket).
   • If required checks get worse (for example: more failing checks, fewer passing checks, or a new blocked required check), stop immediately, apply auto:hold, and publish hold_reason=regression_floor_worsened.
   • If two consecutive attempts show no reduction in failing required checks, stop, apply auto:hold, and publish hold_reason=regression_floor_no_improvement.
5. Limit attempts (default 3). On exhaustion, permission issues, or hard conflicts:
   • Leave a summary comment.
   • Request changes as last resort.
   • Apply auto:hold.

Handoff (no merge)

• When required checks are green (or no required checks exist) and no hold:
  • Update status/comment to indicate: ready for human review/merge.
  • Keep the PR open.
• Policy:
  • Never run gh pr merge (any flags).
  • Never run gh pr review --approve unless explicitly instructed by the user.
• Confirm handoff state:
  • gh pr view <num> --json state,mergeStateStatus,reviewDecision

Adaptive polling

• Poll under 60s unless CI is slow.
• Use recent CI duration to back off (cap at 120s).
• Exponential backoff on API errors.

Status reporting

• Maintain a single PR comment/check-run named Join Operator.
• Update in place (avoid comment spam).
• Include machine-checkable fields in each status update:
  • raw_score
  • score_breakdown (target_pr_hint, entity_overlap, entity_hits, path_overlap, base_branch_match, issue_refs, risk_multiplier)
  • threshold_decision (confidence_threshold, effective_confidence_threshold, risk_threshold_multiplier, score_margin, needs_seq_reasons)
  • conflict_kind (none|routing|merge|policy|permission|ci)
  • complexity (low|medium|high)
  • confidence (0.00-1.00)
  • resolution_hint (actionable next step; none only when resolved)
  • action_taken
  • status (applied|hold|failed|no_match)
  • hold_reason

Gh-only block comment template

Join Operator: gh-only automation block

This PR needs an action outside the gh-only boundary (for example, manual conflict resolution or a local-only edit path).
Apply the needed commit manually, then remove `auto:hold`.

Stalled CI comment template

Join Operator: required checks stalled

Required checks showed no progress for 10 minutes.
Investigate the linked runs, unblock CI, then remove `auto:hold`.
