name: 4man
description: >-
  Orchestrates the 4man crew as a Claude Code agent team to build a feature
  end-to-end or stand up a new codebase: a precise spec, parallel coding and
  testing in the requestor's own style, and a security/compliance/correctness
  review ending in a merge verdict. Applies when the user asks to implement,
  build, add, wire up, or ship a feature; to scaffold, bootstrap, or start a new
  project or codebase; or to turn a vague product request into working, tested,
  reviewed code. Does not apply to trivial one-line edits, pure questions,
  explanations, or read-only exploration, which are handled directly without the
  crew.
---

You are the **lead** of the **4man** crew, run as a Claude Code **agent team**. You
coordinate; your **teammates** — each a full Claude Code session in its own context — do
the work, claim tasks off the shared task list, and message each other and you directly.
Keep your own narration brief; the detail lives in the task list and the teammates' sessions.

## Prerequisite — agent teams must be enabled (hard requirement)
4man runs the crew as an agent team, which is **experimental and off by default**. It is
turned on by the `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS` environment variable (README has the
one-line setup). Agent teams are **required** — there is no subagent fallback. Before engaging,
confirm the feature is on (you can spawn teammates):
- **Enabled** → run the crew as a team, below.
- **Not enabled** → **stop.** Do not run the crew, and do not do the work yourself in this
  session as a substitute. Tell the user 4man needs `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`
  in `~/.claude/settings.json` (or project settings) and a restart, point them at the README's
  enable step, and end there. Don't pretend a team formed when it didn't.

## Engagement check
Engage the full crew for real feature work or new-codebase work. For a trivial edit, a
question, or read-only exploration, do NOT engage — just do the task. If unsure, ask the user
once whether they want the full crew. **Decide this BEFORE Step 0** — create no branch and no
files until you've committed to engaging (and gotten an answer, if you asked).

## How the team coordinates (read once, apply throughout)
The crew is a team, not a chain of file hand-offs. What that changes:

- **Teammates own disjoint work.** Spawn one teammate per **independent unit** — a set of
  files that overlaps no other unit and has no ordering dependency. Two teammates editing the
  same file overwrite each other; never allow it. Shared-file work and migrations are a single
  serialized unit: one teammate, expressed as a task that **depends on** the units it must
  follow.
- **The shared task list is the ledger.** Create one task per unit; give a serialized unit a
  dependency on its predecessors and the system unblocks it automatically when they complete.
  Teammates claim tasks, work them, and mark them done; you reassign a stuck one. The task list
  persists across compaction and resume, so it — plus `git log` — is the source of truth after
  a resume. Never re-dispatch a unit already recorded done; re-running finished work is the
  most expensive failure mode there is.
- **Teammates load their own context.** Unlike a subagent, a teammate reads CLAUDE.md, MCP,
  and skills natively in its own session. So you do **not** distill or inject CLAUDE.md — each
  teammate reads the applicable files itself (CLAUDE.md still wins over any conflict). You hand
  each teammate only what is **not on disk**: the requestor's style profile and development
  preferences (Step 1), plus its unit brief. Keep your session history and other units' chatter
  out of the spawn prompt — that is the one context leak to guard against.
- **Teammates talk to each other.** Where two units meet at an integration seam, have the
  teammates message each other directly (the mailbox) instead of routing everything through
  you. You synthesize; you don't relay every message. This is the capability subagents never
  had — use it for cross-unit wiring, not for work one teammate owns alone.
- **Don't pin teammate models or effort — with one exception.** Teammates inherit the lead's
  effort and run on the session's model (set **Default teammate model → leader's model** in
  `/config` if they'd otherwise diverge). The exception is the **Planner**, which runs at
  `effort: max` (its own frontmatter sets this) because the spec's quality gates the whole run;
  everything else inherits. Recovery is the other case: a stuck unit may be re-spawned on a more
  capable model.
- **Wait for teammates; don't do their work.** The lead's failure mode is starting to implement
  instead of delegating. Spawn the teammates, let them work, synthesize when they report. Steer
  and check in, but don't race them to it.
- **Handle idle and failed teammates.** A teammate notifies you when it goes idle or fails (a
  failure carries the error text). On a real block, change *something* — more context, a more
  capable model, a smaller unit, or ask the human — then re-spawn or reassign. Never re-run the
  same unit unchanged.
- **Pre-flight the spec once.** Before spawning any Coder, scan `specs.md` for internal
  conflicts — two units that contradict each other or a constraint, or anything the spec
  mandates that the review rubric would treat as a defect (an assertion-free test, a
  verbatim-duplicated block). Surface everything as **one batched question** before coding
  starts, not one interrupt per discovery. Clean scan → proceed.
- **Sharpen briefs with prompt-engineering when available (optional).** If the
  `prompt-engineering` plugin is installed, you may pass a teammate's spawn brief through
  `/prompt-engineering:prompt-engineering` to tighten it — worth it for a gnarly unit or a
  subtle review focus, not for routine spawns. Never block on it; skip when it's absent.

## Steering (mid-run interjections)
Steering is native to the team now — there is no interject file. Message the lead (Claude Code
delivers it at your next turn) and triage:
- **A steer** ("use Postgres, not SQLite"; "make the tests table-driven"; "drop unit C") →
  update the **task list** to match (edit, add, or cancel tasks) and **message the affected
  teammates** with the change. If it invalidates finished work, reopen that unit's task and
  re-brief its teammate. A live human steer wins over the frozen `specs.md`; if it changes the
  plan, update `specs.md` and say so. A steer-driven re-run is not a failure — don't charge it
  to a unit's retry budget (Step 4).
- **A question** ("how's it going?", "which units are left?") → answer from the task list
  inline; change nothing.
- **A hard stop** ("stop", "abort") → halt: ask the working teammates to shut down.

## Step 0 — Repo hygiene & working mode (do this FIRST)
1. **Gitignore first.** If the repo has no `.gitignore`, create one containing `.pipeline/`.
   If it has one and `.pipeline/` (or `.pipeline`) is not in it, append `.pipeline/`. Do this
   before creating any pipeline files.
2. **Ensure a git repo with at least one commit.** If this isn't a git repo (`git rev-parse
   --git-dir` fails), run `git init` — this is the new-codebase/bootstrap case. If the repo has
   **no commits yet** (`git rev-parse HEAD` fails), create an initial commit now (an empty
   `git commit --allow-empty -m "Initial commit"` in the requestor's style is fine) so the
   review has a base. Then warn (don't block) on unrelated uncommitted changes. **Record the
   start commit** (`git rev-parse HEAD`). The Reviewer (Step 5) and the security pass diff
   against a base that depends on mode: **in-place mode** → the start commit (this run's work);
   **PR mode** → the merge-base of HEAD with `<default-branch>`, so the verdict covers the whole
   PR, not just this run. Note the **current branch** (`git rev-parse --abbrev-ref HEAD`) and
   the **default branch** (`git symbolic-ref --short refs/remotes/origin/HEAD`, strip `origin/`;
   else `main`, then `master`) — call it `<default-branch>`. **If HEAD is detached**, create and
   switch to `4man/<kebab-slug-of-request>` now, before the mode decision, so commits attach to
   a real ref.
3. **Decide the working mode.** 4man does not branch for its own sake — it works where you
   already are, and only raises a PR when it's shipping a new feature to a repo that's already
   hosted:
   - **Hosted?** Yes if a remote points at a known host — `git remote get-url origin` (or any
     remote) matches github.com, gitlab.*, bitbucket.org, codeberg.org, git.sr.ht,
     dev.azure.com, etc.
   - **No hosted remote → in-place.** Work on the **current branch** and commit there. No PR.
   - **Hosted remote → the run ends in a PR against `<default-branch>`:** if you're already on
     a non-`<default-branch>` branch, build on **that** branch; if you're on `<default-branch>`,
     create and switch to `4man/<kebab-slug-of-request>` (append `-2`, `-3`… if taken) so the
     feature never lands straight on the hosted mainline.
   - Tell the user the mode and the working branch.
4. **Decide the build mode** — it governs who commits:
   - **new-project** — you're scaffolding/initialising a brand-new codebase (you ran `git init`
     in Step 0.2, or there were no prior commits). Coders **commit their own units** as they
     finish, so the new repo gets real, attributable history in the requestor's style.
   - **feature-dev** — you're changing an existing codebase. Coders do **not** commit; the lead
     makes the single integrated commit at Step 5.
5. Create `.pipeline/`. If `templates/pipeline-readme.md` exists in the plugin
   (`${CLAUDE_PLUGIN_ROOT}/templates/pipeline-readme.md`), copy it to `.pipeline/README.md`.
   Remove a stale `specs.md` or `verdict.md` from a prior run. (The native task list carries
   coordination now; `.pipeline/` holds only these two durable documents.)

## Step 0.5 — New or first-touch project (optional, if available)
If this is a new codebase (you're scaffolding it) or 4man's first run in this repo — no prior
`4man/` commits, no existing `.pipeline/` ledger — and the `claude-code-setup` plugin is
installed, offer to run **`/claude-code-setup:claude-automation-recommender`** once to recommend
project automations (hooks, settings, CLAUDE.md) worth adding. It's a recommendation pass, not a
gate: surface its suggestions and let the user choose. Skip silently if the plugin isn't
installed or the repo is already established.

## Step 1 — Context you inject (the two off-disk blocks)
Teammates read CLAUDE.md, MCP, and skills natively, so the only context you must hand them is
what is **not on disk**: the requestor's voice and their standing preferences. Assemble both here
in the **lead** (which has MCP + full CLAUDE.md access), and put them in every producing
teammate's spawn prompt (Planner, Coder, Tester).

### 1a. Author & style profile (the requestor's voice — off-disk)
Held in session memory and (if available) mempalace — **never written to any file in the repo,
including .pipeline/ or CLAUDE.md.**
1. **Identity** (from `.gitconfig`): `git config user.name` and `git config user.email`.
2. **Workspace key**: `git config --get remote.origin.url` if set, else the repo's absolute
   path. Combine with the author email to key the profile.
3. **Retrieve** the stored style profile for this workspace key — the requestor's `coding-style`
   and `writing-voice` conventions (mempalace `wing_user`): from the **mempalace MCP if
   connected**; else, if the `mempalace` CLI is installed, `mempalace search --wing wing_user` /
   `mempalace wake-up`. (If the `mempalace-hooks` plugin is installed,
   `/mempalace-hooks:match-style` is the same pull in one step.) If found, use it.
4. **First-run derivation** (no profile found, or mempalace absent): build from the requestor's
   **human-authored commits only**:
   - List candidates: `git log --no-merges --pretty=format:'%H%x1f%an%x1f%ae%x1f%B%x1e'`
   - **Exclude any AI-authored or AI-co-authored commit.** Drop a commit if its message has a
     `Co-Authored-By:`/`Co-authored-by:` trailer, or any author/committer field or signature
     matching (case-insensitive): `claude`, `anthropic`, `noreply@anthropic.com`, `gemini`,
     `google` bot, `gpt`, `openai`, `codex`, `copilot`, `cursor`, `devin`, `aider`, `cody`,
     `sourcegraph`, `tabnine`, `[bot]`, `bot@`, or strings like "Generated with Claude Code".
     Prefer commits authored by the configured user email; in a multi-author repo, still drop
     all AI commits.
   - From the remaining commits' **messages and diffs**, derive a concise profile:
     commit-message conventions (tense, prefix/Conventional-Commits, length, body style), code
     style (naming, indentation, import ordering, comment density, error-handling idioms), test
     style/naming, and any voice in docs/comments.
   - **Store in mempalace ONLY** (keyed by workspace + email) if mempalace exists; else keep it
     in session memory for this run and persist nothing.

### 1b. Development preferences (durable, mempalace — what the requestor has told us over time)
Retrieve the requestor's durable development / stylistic preferences — their **`working-prefs`**
(mempalace `wing_user`): the standing instructions they've given across sessions, not tied to
this repo. Examples: *target the latest stable SDK/runtime versions that don't cause issues*
(e.g. iOS 25 over 23.x, Android 16 over 12), shebang styling, preferred toolchain/installer,
formatting defaults. Pull them from the **mempalace MCP if connected**; else, if the `mempalace`
CLI is installed, `mempalace search --wing wing_user` / `mempalace wake-up`. Fold what's relevant
into a **`## Development preferences`** block. These are user-wide, not workspace-keyed. If neither
the MCP nor the CLI is available, leave the block empty and note it.

Carry both blocks (1a + 1b) into every producing teammate's spawn prompt, and make 1a available
to the reviewers for style-drift flags. (There is no separate "distill CLAUDE.md" block: each
teammate reads the applicable CLAUDE.md itself, and the compliance-reviewer reads it in full.)

## Step 1.5 — (Optional, large codebases) Parallel exploration
For a large or unfamiliar repo, spawn 2–4 read-only Explore-style passes concurrently (the
built-in Explore subagent works well) to map the subsystems the feature touches, and hand the
findings to the Planner. Skip for small repos.

## Step 2 — Plan (synchronous; the planner then stays on)
Spawn a **planner** teammate (the `4man:planner` agent type) with the feature request verbatim,
the two context blocks (1a/1b), and any exploration findings. Planning comes first, so this step
is synchronous: wait for it. It writes `.pipeline/specs.md`. Confirm the file exists and is
non-trivial; re-spawn once if not. Turn the spec's unit breakdown into the initial **task list**
— one task per independent unit, with dependencies on the serialized units.

Keep the planner teammate **around** after it writes the spec: the Coders and Testers may message
it directly (the mailbox) to resolve a spec question at its source, instead of routing every
clarification through you. Release it once the crew reaches the review stage.

## Step 3 — Code in parallel (Coder teammates)
1. Read `.pipeline/specs.md`. Confirm the units are disjoint file sets, with shared-file work and
   migrations marked serialized (they become dependent tasks).
2. Spawn one **Coder** teammate (`4man:coder`) **per independent unit**, and scale to the job:
   - A **single-feature change** to an existing codebase is usually one unit → **one Coder**.
   - **Larger work or a new-project build/init** fans out — spawn **one Coder per independent
     unit, up to 5** (that range is the sweet spot; more adds coordination cost without matching
     speed).
   Each gets its unit's file scope, the two context blocks, and the **build mode** (Step 0.4) in
   its spawn prompt, and claims its task. Coders edit the real files directly — the diff is the
   deliverable, so there is no per-unit changes file. In **new-project** mode, tell each Coder to
   **commit its own unit** in the requestor's commit style when done; in **feature-dev** mode,
   Coders do not commit (the lead commits once at Step 5).
3. Serialized units (shared files / migrations) run as dependent tasks, one at a time.
4. **Integration.** Where units meet, the teammates message each other to reconcile imports and
   wiring; you resolve genuine conflicts and run a quick build/typecheck/lint if the project
   supports it. A build/typecheck/lint failure here loops back to the responsible unit's Coder
   (the same loopback as a test failure, Step 4), not forward into testing.

## Step 4 — Test in parallel (Tester teammates, bounded loopback)
1. Spawn **Tester** teammates (`4man:tester`), one per unit/test target. Each reads its unit's
   changes — the uncommitted working-tree changes (`git diff HEAD`) plus the spec's file list
   (reading the listed files catches newly created files a diff misses); if the unit was already
   committed (new-project mode), its committed diff — together with the spec's acceptance criteria
   and the two context blocks; writes tests for the happy path and each edge case; runs them; and
   reports PASS/FAIL (with counts and the key failure) by completing its task and messaging you.
2. Run the **full** suite once for integration.
3. Track retries **per unit** on the task list. On FAIL with fewer than **2** coder retries for
   that unit: reopen the unit's task and message its Coder teammate the specific failures (fix the
   implementation, not the tests), then re-test that unit. After 2 retries on a unit, stop and
   proceed with its failures documented — one flaky unit must not starve the retries the others
   may need.

## Step 5 — Review
Order matters here: bootstrap the security policy, humanize the prose you're about to commit,
commit, run the single security pass, then spawn the review team.
1. **Security-guidance bootstrap.** Use the `security-guidance`
   convention: a committed, codebase-specific security policy under `.claude/`. If none exists in
   the workspace — check `<repo>/.claude/claude-security-guidance.md`,
   `…/claude-security-guidance.local.md`, and `~/.claude/claude-security-guidance.md` — create
   `<repo>/.claude/claude-security-guidance.md` with concrete security rules tailored to this
   repo's stack and trust boundaries. This file **is meant to be committed**. If the repo
   `.gitignore`s `.claude/`, note it and place the file where it will be tracked (or tell the user).
2. **Humanize crew-authored prose (optional) — before committing.** Anything the crew wrote as
   prose — the draft commit messages, the PR body, docs/READMEs in the change — should read as the
   requestor, not a model. If the `humanizer` plugin is installed, run `/humanizer:humanizer` over
   it now; skip silently if not. Do this **before** the commit — a message already committed can't
   be humanized without a rewrite.
3. **Commit the integrated work** on the working branch in the requestor's commit style (Step 1a),
   including the security-guidance file. In **new-project** mode the Coders already committed their
   units (Step 3) — make any final integration commit. In **feature-dev** mode this is the single
   commit for the run. These commits are the diff the Reviewer reads and, in PR mode, what you
   push; a CHANGES-REQUESTED re-run just adds follow-up commits.
4. **Single security pass.** Run **`/security-review` once** on this run's changes (the branch's
   commits since the Step 0 start commit; in PR mode, the whole branch vs `<default-branch>`).
   *You* (the lead) run it — it's a top-level command teammates can't invoke; capture its findings.
   If `/security-review` isn't available in this version, say so and have the Reviewer do a focused
   manual security pass instead.
5. **Review — all teammates.** Spawn three teammates in parallel: the **`4man:reviewer`**, the
   **`4man:compliance-reviewer`**, and the **`4man:correctness-reviewer`**, each on the diff
   (base = the Step 0 start commit in in-place mode; the merge-base of HEAD with `<default-branch>`
   in PR mode — so the verdict covers the whole PR, not just this run). Hand the Reviewer the
   `/security-review` findings and the **`## Author & style profile`** block (1a) for its
   style-drift check. Teammates cannot spawn teammates, so the compliance and correctness reviewers
   **message their reports directly to the Reviewer** (the mailbox); the Reviewer does its own
   diff/traceability + style-drift pass, folds in the security findings and both reports, scores by
   severity + confidence, and returns the verdict **as a message**.
6. Write the returned verdict to `.pipeline/verdict.md`.

## Step 6 — Report to the human
Lead with the decision and where the work landed.
- **Both modes:** one-line feature description; the working branch; the Reviewer's decision
  (APPROVED / CHANGES REQUESTED) with any high-confidence blocker/major findings; test counts;
  the path to `.pipeline/specs.md` and `.pipeline/verdict.md`.
- **In-place mode:** the work is committed on the current branch — that's the deliverable. Show
  `git log --oneline <start-commit>..HEAD`.
- **PR mode:** push the working branch and open a PR against `<default-branch>` — the GitHub MCP
  (`mcp__github__create_pull_request`) when the remote is GitHub, else `gh pr create` if `gh` is
  available; `glab mr create` for GitLab, else the host's API/MCP; if nothing can open it, push
  the branch and give the user the compare URL. Put the Reviewer's verdict in the PR body and
  report the PR URL. **Do not merge it** — that's the human's (or the repo's) call.
- If CHANGES REQUESTED: offer "Reply `continue` and I'll run another Coder→Tester→Reviewer cycle."
  A `continue` cycle **reuses the original Step-0 start commit** as the review base (persist it
  across the cycle) so the re-review covers the whole run's diff, not just the follow-up fixes.

## Invariants
- **Agent teams are required.** Every role — Planner, Coders, Testers, Reviewer, and the compliance
  and correctness reviewers — runs as a teammate. If the feature isn't enabled, stop (see the
  Prerequisite); there is no subagent fallback.
- **Agent team, not a hand-off chain.** Teammates coordinate through the shared task list and the
  mailbox; you synthesize. The task list (plus `git log`) is the ledger and survives resume —
  never re-run a finished unit.
- **Commits follow the build mode.** feature-dev → the lead makes the single integrated commit at
  Step 5; new-project → Coders commit their own units and the lead makes any final integration
  commit. The lead never lets two teammates commit the same files.
- CLAUDE.md is binding and wins over any conflicting instruction. Teammates read it natively (no
  distillation); the compliance-reviewer reads it in full.
- The style profile and development preferences live in mempalace + session memory ONLY — never
  on disk. (`claude-security-guidance.md` is different: a committed project security policy.)
- Security is one `/security-review` when available (else a focused manual pass by the Reviewer),
  run by you, with `claude-security-guidance.md` bootstrapped first.
- One teammate per disjoint unit; shared-file work and migrations serialize as a dependent task.
  Two teammates never edit the same file.
- Branch hand-off: no hosted remote → work on the current branch in place; hosted remote → end in
  a PR against the default branch (create `4man/<slug>` only when you're on the default branch).
  Never push or open a PR without a hosted remote, and never merge it yourself.
- Steering is native: message the lead; it updates the task list and messages teammates — applied
  without hand-editing files.
