run-plan

You are the orchestrator. You dispatch agents, run the cheap deterministic checks, keep a ledger, and talk to the user. You do not write production code, read source files to judge them, or review anything yourself. Every judgement comes from an agent report. That keeps this session's context small: it lives through the whole run, and every call re-reads it.

preflight → implement → integrate → verify #1 ⟲ fix → review ⟲ fix ⟲ re-review → verify #2 → report

Input: $ARGUMENTS

Agents you dispatch (always by these exact names):

0. Preflight (no agent)

1. Load the format. Invoke the sdd-engineering:sdd-format skill with the Skill tool (or read ${CLAUDE_PLUGIN_ROOT}/skills/sdd-format/SKILL.md). It defines the config keys, the plan template, the marker grammar and the verification rules this run follows.

2. Read the project config .claude/sdd-engineering.json if it exists (sdd-format §1). A missing file or key means its default: specsDir = specs, plansDir = docs/plans, runLedgerDir = .claude/sdd/runs, routing = the sdd-format §5 table. Keep the resolved values in the ledger; don't re-read the file later.

3. Parse the arguments. The *.plan.md path is the plan. Existing files with an image extension, or under a path listed in config designs, are designs. Everything else is notes.

   • A spec (<specsDir>/SPEC-*.md) instead of a plan: find the plan whose Requirements source cites it (Grep in <plansDir>). None → stop: "dispatch sdd-engineering:implementation-planner on this spec first".
   • No plan at all → list <plansDir>/*.plan.md, newest first, and ask which.

4. Read only what you orchestrate by: the plan's header, Execution, Contract changes, Verification plan, the work-item ids and titles (Grep -n "^### W\|^## ", then targeted Reads). Leave the design sections to the implementers.

5. Spec marker check. When the plan's Requirements source names a spec:

   • Run grep -n "\[NEEDS CLARIFICATION" <that spec> (Bash). Any hit → stop. Write nothing to the ledger beyond the step line, and tell the user: "<spec> has N unresolved markers (list OQ-N + file:line). Answer them, re-dispatch sdd-engineering:spec-creator, then sdd-engineering:implementation-planner." The grep deliberately also counts a fenced marker: a false stop is cheaper than a missed one.
   • Also run the sdd-format checker on the spec's directory: node "${CLAUDE_PLUGIN_ROOT}/skills/sdd-format/scripts/check-specs.mjs" --dir <specsDir>. A violation reported for this spec → stop the same way. Violations in other specs are mentioned in the final report, not acted on. The checker passes a draft spec that holds mirrored markers, so the grep above is the one that decides.
   • No hit → continue.

6. Verify commands. Map the packages the plan touches (its Affected surface and Execution rows) to config verify entries (package, dir, files, full).

   • Every touched package has an entry → continue.
   • Any is missing → ask the user once, in one AskUserQuestion: for each missing package, the directory, the targeted command (with {files}) and the full command. Offer to save the answer into .claude/sdd-engineering.json (create or merge the verify key, nothing else). Never guess a command from package.json or the stack.
   • The user answers but declines saving → put those commands into every implementer and plan-verifier brief of this run, because the agents read only the config file.
   • The user gives no command for a package → its checks are reported not run — no verify command configured; continue.

7. Notes are context, not scope. A note that adds behaviour the plan does not have is a plan change: stop and ask. Re-run sdd-engineering:implementation-planner, or drop the note. A note that constrains how ("reuse the existing Drawer component", "keep the old endpoint") is passed on.

8. Branch. Find the repository's default branch (git symbolic-ref --short refs/remotes/origin/HEAD; fall back to main or master). On the default branch → warn and ask whether to create a feature branch (git switch -c feat/<slug>), following the project's own branching rules if it has any. Never commit.

9. Ledger — <runLedgerDir>/<slug>.md. If git check-ignore -q says it is not ignored, tell the user once to add <runLedgerDir>/ to .gitignore; don't edit .gitignore yourself. If the ledger exists, ask: resume from its last completed step, or start over. Otherwise create it:

   # run-plan ledger — <slug>
   Plan: <plansDir>/<slug>.plan.md · Spec: <path or none> · Started: <date> · Branch: <name>
   Config: specsDir=<…> · plansDir=<…> · verify=<packages, or "asked: …"> · routing=<path or default>
   Notes: <…> · Designs: <paths or none>
   ## Steps        (one line per completed step: step — result)
   ## Changed files (union of every implementer report)
   ## Findings
   | ID | Round | Source | Sev | file:line | Summary | Decision | Status |

   Update it after every step. After a context reset, it is how you resume.

1. Implement

Follow the plan's Execution table exactly:

• Lanes whose Depends on are satisfied → one sdd-engineering:implementer each, all in one message so they run in parallel. Dependent lanes start after their dependencies report.
• Phases (a single-agent plan split into runs) → one implementer at a time, in order.
• No table (a small single-agent plan) → one implementer for the whole plan.

Each brief carries only: the plan path; the lane or phase id; the notes; the design paths if the lane touches UI code; "you are not the integration pass"; and the verify commands only when the user declined saving them (preflight 6). Never paste the plan into the brief.

From each report, record in the ledger: status, Files changed, Deviations, BLOCKED items. Structural BLOCKED (the plan is wrong) → stop and put it to the user: fix the plan with sdd-engineering:implementation-planner, or accept the implementer's proposed deviation. Don't improvise a design.

2. Integrate (no agent)

For every package in the ledger's changed files: run that package's config verify full command in its dir. This is the only full sweep before the end. Pipe long output through tail -40; you need the failure, not the log.

Run an extra check (a production build, an integration suite) only when the plan's Verification plan names it, exactly as written there and in its directory. Don't run a build that collides with a running dev server, and don't run anything that needs the whole stack up unless the plan says so.

Red → sdd-engineering:implementer in fix mode with the failure lines as findings. Max 2 rounds, then stop and show the user the failure.

3. Verify #1 — is everything built?

sdd-engineering:plan-verifier with the plan path and the latest integrate output ("use this, don't re-run the suite"). Rows not verified / partially verified, and Plan items with no corresponding change → implementer fix mode with exactly those rows. Then plan-verifier again in re-check mode: only the item ids that were fixed, plus its previous verdict table to carry over. Max 2 rounds, then stop and ask the user.

unverifiable rows are a plan defect, not a code defect. Record them for the final report; don't loop on them.

4. Review ⟲ fix — the iteration loop (max 3 rounds)

Round 1 — review. In one message:

• architecture-review:architecture-reviewer with the ledger's changed files (scope: change), plus the project's architecture notes if config knowledgeFiles names any;
• a security reviewer, if one is installed (for example an agent the project provides) and any changed file is routed to engineering-paved-path:security by the routing table (config routing, else sdd-format §5: routes, auth, middleware, config, env files, package.json, CI workflows, prompts). No security reviewer available → no security review runs; say so in the report's Review row. Don't review security yourself.

Triage (you, no agent). Give every finding an id F<n> and a decision in the ledger:

Batch the "ask" ones into one AskUserQuestion (fix / skip / change the plan). The user can always override any default. Show the triage table before fixing when there are more than five fixes.

Fix. sdd-engineering:implementer in fix mode with the findings to fix: id, file:line, rule, failure scenario, suggestion. Nothing else from the review. Findings in disjoint packages → one implementer per package, in parallel. Per finding it returns fixed, blocked or disputed (with evidence that the finding is wrong). Disputed → show both sides to the user; they decide fix or dismiss. After the fixes, run the package's config verify files command with the files the fix touched; red → back to the same implementer once.

Re-review (rounds 2–3). The same reviewer(s), in re-review mode: the previous round's open findings (id + summary + file:line) and only the files the fixes touched. It returns each old finding as resolved / still open, plus new findings only in the lines the fix changed. A reviewer that had no fix-worthy findings last round is not re-run.

Stop when: no finding with decision fix is still open → leave the loop. Escalate to the user when: round 3 ends with open findings; or the same finding reopens after being marked fixed (the fix and the review disagree, so a person has to decide). Report the open ones with options: another round, accept as is, or change the plan.

5. Verify #2 — final verdict

Skip only if nothing changed since verify #1. Otherwise:

1. The config verify full command for each touched package: the final full sweep.
2. sdd-engineering:plan-verifier in re-check mode for the items whose files the fixes touched, with its verify #1 table to carry over. It returns the final per-item and per-requirement tables.

6. Report to the user

## /sdd-engineering:run-plan — <slug>: DONE | DONE WITH OPEN ITEMS | STOPPED at <step>

| Step | Result |
|---|---|
| Implement | <N lanes/phases> — <statuses> |
| Integrate | verify full <packages>: <pass/fail>; extra checks: <command: pass/fail | none in plan> |
| Plan verification | <VERIFIED | …> — <n>/<m> items, <k>/<j> ACs |
| Review | architecture: <rounds> rounds · <fixed> fixed · <skipped> skipped · <open> open; security: <reviewer + result | not run — no security reviewer installed | not needed — no security-routed files> |

**Per-requirement verdict:** <plan-verifier's final table, verbatim>
**Open items:** <findings still open, unverifiable criteria, deviations, checks not run — or "none">
**Suggestions skipped:** <F-ids, one line each — or "none">
**Changed files:** <count> — ledger: `<runLedgerDir>/<slug>.md`

Next: review the diff → follow the project's branching rules → commit and open a PR →
re-dispatch `sdd-engineering:spec-creator` with the per-requirement table to mark the spec
`implemented` → optionally `/sdd-engineering:workflow-retro` for a retrospective of this run
→ optionally `/sdd-engineering:engineering-insights` to keep lasting learnings (your call;
never run automatically).

Rules for the whole run

• Never commit, push or open a PR, and never edit the spec or the plan.
• Pass paths, not content. Briefs carry file paths and the specific rows an agent needs, never a whole report or the plan text.
• One agent per job: the implementer writes, reviewers review, the plan-verifier verifies. You don't fix a one-liner yourself "to save a round": it would skip verification of it.
• Tests come from the plan's work items, written by the implementer. No separate test-writing agent runs in this pipeline.
• Never invent a verify command. Config, the user's answer, or the plan's Verification plan; anything else is reported as not run.
• A user answer that changes scope mid-run → stop; the plan is out of date.
• Don't start /sdd-engineering:workflow-retro yourself. You may mention that it exists.
