PR Workflow

Governed PR creation: full commit pipeline, pre-push gates, structured PR (summary + test plan), auto-complete with squash merge and branch deletion.

Canonical chain step brainstorm → plan → build → pr: runs the commit pipeline internally, so the operator does NOT run /ai-commit first (/ai-commit is the off-chain WIP-only skill, no PR).

/ai-pr                  # full pipeline + create or update PR
/ai-pr --draft          # open as draft (no review request)
/ai-pr review           # request review on existing PR
/ai-pr update           # refresh PR body + push amended commit

Process

In order: decision preamble (resolve once), Steps 0-6 (inline commit pipeline), the concurrent docs + pre-push block (Step 7), then PR create, consolidate, and watch through Step 17.

Decision preamble (resolve once, before Step 0; later steps read, never re-decide)

Flag	Detect	Effect
draft?	--draft	skip review request, consolidation (Step 14b), watch loop
existing_pr?	gh pr list --head <branch> / az repos pr list finds a PR	extend, never overwrite
placeholder_spec?	spec.md == # No active spec	skip spec ops + consolidation, fall back to label-based PR body

Steps 0-6: Inline Commit Pipeline

0. Auto-branch from main/master: infer type (feat/, fix/, chore/, docs/, refactor/), generate slug via python3 .ai-engineering/scripts/branch_slug.py --prefix <type>, then git checkout -b <output>.
1. Work-item context (opt): spec.md frontmatter refs → commit body trailers (Refs: AB#101, #45); only close_on_pr items, never features.
2. Instinct consolidation: if .ai-engineering/observations/observations.yml exists, run /ai-session-watch --review before committing.
3. Stage selectively (git add <file>...). git add -A only when explicitly requested. Exclude generated files, secrets, large binaries.
4. Run gate orchestrator: ai-eng gate run --cache-aware --json --mode=local. The 2-wave collector (Wave 1 fixers serial → Wave 2 checkers parallel) emits .ai-engineering/state/gate-findings.json (schema v1); Wave 1 re-stages the safe S_pre & M_post intersection (D-105-09; disable via --no-auto-stage or manifest gates.pre_commit.auto_stage: false).
5. Handle gate: exit 0 → continue. Exit non-zero → STOP, fix root cause, re-run. Publish-window override: ai-eng risk accept-all .ai-engineering/state/gate-findings.json --justification "<reason>" --spec <id> --follow-up "<plan>" (see .ai-engineering/reference/risk-acceptance-flow.md).
6. Docs gate inside the orchestrator is mandatory; see .ai-engineering/reference/gate-policy.md for the local fast-slice + CI authoritative split.

7. Concurrent dispatch — docs + pre-push gate (3 lanes)

Docs subagents and the pre-push gate run in parallel — wall-clock = max(docs, pre-push), NOT sum. Docs are produced and staged BEFORE PR creation so the description stays coherent.

1. Read flags from .ai-engineering/manifest.yml (documentation.auto_update, external_portal).
2. Compute diff once — git diff main...HEAD. Pass to both docs agents.
3. Dispatch 3 concurrent lanes, block on max(lane1, lane2, lane3):
   • Lane 1 — docs A1: /ai-docs changelog + /ai-docs readme (if enabled).
   • Lane 2 — docs A2: /ai-docs solution-intent-sync (if architecture changed) + /ai-docs docs-portal + /ai-docs docs-quality-gate. Zero uncovered items required.
   • Lane 3 — pre-push gate: dispatched concurrently here; Step 9 owns the full description. Do not restate the gate command in both places.
4. Stage all docs files produced by lanes 1-2 BEFORE PR creation. spec-104 NG-7 forbids deferring docs to a separate commit — regulated audience requires clean audit history.

9. Pre-push gate (canonical description; concurrent Lane 3 of step 7)

ai-eng gate run --cache-aware --json --mode=local runs Wave 1 fixers (ruff format → ruff check --fix → spec verify --fix) in parallel with Wave 2 checkers (gitleaks protect --staged, ty check src/, pytest -m smoke, ai-eng validate, docs gate). CI uses --mode=ci (adds semgrep, pip-audit, full pytest matrix). Non-zero exit → parse gate-findings.json, report, STOP; resolve or accept via ai-eng risk accept-all (see .ai-engineering/reference/risk-acceptance-flow.md).

10. Work item context

Read .ai-engineering/manifest.yml work_items and spec.md frontmatter refs (yaml shape: features never close; user_stories/tasks/bugs/issues close on PR merge).

11. Spec operations (PR body)

If .ai-engineering/specs/spec.md is non-placeholder: read spec.md + plan.md to generate the PR description; run ai-eng spec verify --fix; update spec.md/plan.md to reflect ACTUAL scope; use the updated content for the PR body (Summary from spec, Test Plan from plan). Consolidation does NOT happen here — per D-167-07 it runs pre-merge on the feature branch in Step 14b, so the archive + slot-clear ride this same PR (no separate follow-up chore PR).

12. Work item references

If frontmatter has refs:

• close_on_pr items (user_stories, tasks, bugs, issues): GitHub Closes #N per line; Azure AB#NNN (auto-closes on merge).
• never_close items (features): Related: AB#100 only — NEVER close features (absolute rule).
• No refs: fall back to spec-label-based linking.

13. Commit, push, detect VCS, find existing PR

Compose the commit subject deterministically (spec-139 M8 D-139-06): derive the description from the current .ai-engineering/specs/plan.md task title (grep -m1 '^- \[ \] ' .ai-engineering/specs/plan.md) and pass it via python3 .ai-engineering/scripts/commit_compose.py --type <type> [--task X.Y] --desc "$TASK_TITLE". --desc is mandatory; the legacy <DESC> placeholder fallback is deprecated for the PR pipeline. Push to current branch (block on main/master). Detect provider via manifest.yml providers.vcs.primary, fallback to git remote get-url origin parsing (github.com → gh, dev.azure.com → az repos). Find existing PR with gh pr list --head <branch> or az repos pr list --source-branch <branch>.

14. Create or update PR

Runs after the 3-lane block resolves so the body is coherent (CHANGELOG/README staged, gate passed). Compose body deterministically: python3 .ai-engineering/scripts/pr_body_compose.py reads .ai-engineering/specs/spec.md frontmatter (summary: field — mandatory per spec-139 M8 D-139-06 after the 2026-06-16 cutover) plus plan.md [ ] rows and emits Summary, Test Plan, Work Items, Checklist sections.

• summary: present → Summary composed without any LLM call.
• Legacy specs lacking the field fall back to --bullets-prompt "<llm-bullets>" plus an advisory to backfill summary:. Do NOT pass --bullets-prompt when the spec already declares summary:.
• The PR body (## Summary and every composed section) is a deterministic machine artifact — a carve-out emitted exactly as pr_body_compose.py renders it. The value lens applies only to the operator-facing status report (Step 16), never to the PR body, commit messages, or gate verdicts.

New: gh pr create --title "<t>" --body "<b>" or az repos pr create --source-branch <b> --target-branch <t> --title "<t>" --description "<b>".

Existing (extend, NEVER overwrite): read existing body; if ## Additional Changes exists, append a ### <date> / <commit-range> sub-heading underneath; otherwise append \n\n---\n\n## Additional Changes first. Update via gh pr edit or az repos pr update.

14b. Consolidate on the feature branch (pre-merge, D-167-07)

Runs after Step 14 (PR number N known), before Step 15 auto-complete; skip for --draft (a draft is not merging — consolidate on promotion, else it sits SHIPPED while open). If .ai-engineering/specs/spec.md is non-placeholder, resolve the numeric id from its frontmatter spec: (canonical spec-NNN, not the slug — D-153-01) and run python .ai-engineering/scripts/spec_lifecycle.py mark_shipped <spec-NNN> N <branch> directly — NOT via _shared/consolidate-spec.md, whose SHIPPED-precondition guard would reject the still-IN_PROGRESS pre-merge spec (marking it SHIPPED as the ship-PR opens is the intent). It walks state→SHIPPED, appends the 7-col _history.md row, snapshots spec.md+plan.md into archive/spec-NNN-<slug>/, clears both to placeholders, and emits the audit event. Then git add the archived+cleared files, commit chore(spec-NNN): consolidate (archive + clear live slot), and push so the open PR updates. Fail-open: a write failure logs, never blocks. Consolidation rides the PR regardless of gh/az/web-UI merge — no separate chore PR; the same handler stays manual via /ai-pr --consolidate-spec, and /ai-branch-cleanup reconcile_merged is now a no-op backstop.

15. Board sync + enable auto-complete

For new PRs with refs: invoke /ai-board sync in_review <ref> for each non-never_close ref (fail-open: never block on failure). Then enable auto-complete: gh pr merge --auto --squash --delete-branch or az repos pr update --id <id> --auto-complete true --squash true --delete-source-branch true.

16. Watch and fix until merge

Auto-complete only queues the merge — CI must pass first. The Step 14b consolidation commit is already on the branch, so the CI run the loop watches is the FINAL commit set — and it runs against the idle # No active spec slot (D-167-07); every spec.md-reading gate must tolerate that placeholder. Enter the watch-and-fix loop per handlers/watch.md. It polls every 1 min (active) or 3 min (passive), autonomously fixes CI failures and merge conflicts, handles team/org-internal-bot review comments, and escalates after 3 failed attempts on the same check or wall-clock cap. Drafts skip the loop entirely.

Once state == "MERGED": run /ai-branch-cleanup --all and report to the operator using the value block per .ai-engineering/reference/value-lens.md (bottom line, impact, risk, next) at the resolved audience level (default full). This report and the Step 14 PR-opened status are the user-facing surface the lens governs; the PR body, commit messages, and gate verdicts stay machine carve-outs.

17. Self-verify (terminal)

Turn "did every step run?" into a checkable post-condition — the catch for a silently-skipped consolidation (the PR #190 class). Re-read + assert; any failure → STOP loud, naming the skip.

• Always assert: the step-7 CHANGELOG/README edits rode this commit (not deferred); the Step 14 PR number resolves (gh pr view <N> / az repos pr show).
• Unless draft? or placeholder_spec? (nothing consolidated), also assert: spec.md/plan.md cleared to the # No active spec/# No active plan placeholders; _history.md carries the spec-NNN row.

/pr --only / /pr --draft

--only: skip commit pipeline (verify branch pushed, detect VCS, create/update PR, enable auto-complete). --draft: open as draft.

PR Structure

Title: type(scope): description or spec-NNN: Task X.Y — description (max 72 chars). Body: ## Summary (2-3 bullets), ## Test Plan (verification steps), ## Work Items (Closes AB#NNN — only close_on_pr items), ## Checklist (lint/secret/tests/CHANGELOG/breaking-changes).

Drift recovery

Exit 78 = stack drift. Run ai-eng doctor --fix in shell, retry. Never --no-verify. See .ai-engineering/reference/cli-reference.md for the 6-stack tool matrix.

Examples

User: "I'm ready for review on this branch" → /ai-pr: runs the commit pipeline (0-6), pre-push gates, generates the PR body from the spec's Summary + Test Plan, opens via gh pr create, transitions board state, watches CI. --draft runs the same pipeline but opens as draft, skipping the review request until /ai-pr review.

Quick Reference

Goal	Command
Open PR (default)	/ai-pr
Open as draft	/ai-pr --draft
Skip CI watch	/ai-pr --no-watch
Update existing PR	/ai-pr --update
Resume after merge	/ai-branch-cleanup (auto-invoked)

Integration

Calls: /ai-docs subagents (CHANGELOG, README, portal, quality-gate), /ai-board sync (post-create), gh pr create / az repos pr create. Runs inline: commit pipeline (Steps 0-6 — same logic as the standalone /ai-commit skill, copied for chain clarity). Watches: CI via handlers/watch.md. Reads: manifest.yml, spec frontmatter for linked work items. See also: /ai-commit (off-chain WIP-only), /ai-review, /ai-resolve-conflicts.
