Agent Skills: Verify Brigade

Prove a Brigade change works by driving the real `brigade` CLI against a throwaway temp target, then capture receipts as evidence. Use when you changed anything under src/brigade/ and need proof beyond pytest - init/doctor wiring, work-verify receipts, Grok Bot connector packs, feed manifests, handoff lint. Also use before claiming a CLI behavior in a PR body, handoff, or job report.

Verify Brigade

This skill verifies the brigade CLI against a temp target. The optional Center dashboard is a separate surface. Run the CLI and read what it wrote. This skill drives it through one helper, control-brigade.py, so a proof is a rerunnable command instead of a story.

Every drive happens in a temp target this skill creates. The helper enforces that: --target is accepted only when it resolves under <state-root>/targets, so the operator home, the Brigade checkout, and every other path are refused before a command runs. The state root gets the same treatment whether it comes from --root or from the default - resolved, refused if it resolves to or contains the home directory or the checkout, and refused if it is a symlink at the root or at targets//captures/, so a link planted in a world-writable temp dir cannot redirect a drive. cleanup removes only paths new-target recorded. AGENTS.md forbids driving the real workspace anyway; here it is not reachable.

What that paragraph does not claim:

  • A path under the temp base is allowed even when $TMPDIR sits inside the home directory. That is the only carve-out, and it is exactly that narrow: the home and checkout refusals run first, so the allowance applies only when the temp base itself resolves inside the home directory and outside the checkout. A $TMPDIR inside the checkout is still refused, and a relative $TMPDIR is refused outright rather than resolved against the working directory. The temp base itself is refused - a state root there would chmod the shared scratch tree to 0700.
  • The default evidence root is <checkout>/.brigade/verification-evidence, which is inside the checkout. That is the one deliberate exception: it is gitignored, and it sits outside the state root on purpose so cleanup cannot reach the proof. The default and --evidence-root are both guarded like --root, symlink check included: a link planted at either is refused, not followed. --label names the directory under that root, so it must be a simple [A-Za-z0-9._-] name of 1-64 characters - no separators, no ...
  • grokbot-feed --manifest is the one flag outside the target contract. It is a caller-supplied path, read for validation only and never written, so an operator can validate a real private feed manifest from wherever it lives. Everything the drive writes still lands in the target or the state root.

Launch

There is no long-running process. "Launch" means: have a Brigade CLI, and have a fresh target to drive it against.

# fresh checkout (this repo). Quote the extras so the shell does not glob them.
python3 -m venv .venv
.venv/bin/pip install -e ".[dev,grokbot]"

Observed on this checkout: that install printed Successfully installed ... brigade-cli-0.27.0 ... mcp-2.1.1 ..., and .venv/bin/brigade --version then printed brigade 0.27.0. The grokbot extra pulls the optional mcp package (pyproject.toml: grokbot = ["mcp>=2,<3"]). The [dev] extra alone is enough for pytest / ruff / mypy; add grokbot when the change touches the listener.

Create the target:

registry/skills/verify-brigade/control-brigade.py new-target

That prints one JSON object. It ran git init -q -b main and brigade init --depth workspace --harnesses claude,codex in a new directory under the state root ($TMPDIR/verify-brigade/targets/<stamp>-<rand>), and recorded the path so cleanup can find it later. Ready is "ok": true plus the "target" path; export it:

TARGET=$(registry/skills/verify-brigade/control-brigade.py new-target \
  | python3 -c 'import json,sys; print(json.load(sys.stdin)["target"])')

new-target records the path before it runs brigade init, so cleanup can reclaim it even when that init fails; a failed init also removes the directory it made. --dry-run prints the two commands and creates nothing.

To drive an existing directory you already made under <state-root>/targets (instead of letting new-target make one), init runs the same brigade init against it:

registry/skills/verify-brigade/control-brigade.py init --target "$TARGET" \
  --depth workspace --harnesses claude,codex

Teardown is the cleanup section below. Run it after every attempt, including failed ones, so broken runs do not leave targets behind.

Doctor

One read-only check that answers "is this rig worth driving?" - before blaming Brigade for a drive that fails:

registry/skills/verify-brigade/control-brigade.py doctor

It resolves the Brigade command (--brigade, then $BRIGADE_BIN, then .venv/bin/brigade, then PATH, then python -m brigade), reports its version, and checks git, the checkout, and a writable state root. "ok": true means drive. Anything "fail" means fix that first.

Against a target that already exists, the equivalent question is:

registry/skills/verify-brigade/control-brigade.py doctor-target --target "$TARGET"

"summary": {"failed": 0, ...} is the success signal. warn counts above zero are normal on a fresh target - memory-care, security, and backups are not initialized yet.

Against this checkout itself (the development tree, not a temp target):

.venv/bin/brigade doctor --target .
.venv/bin/brigade status --target .

Observed here, both exit 0. Doctor printed summary: 43 checks, 0 failed, 0 manual and a list of warn rows (missing operator bootstrap files, unwired memory-care / security). Status printed group rows (core, skills, memory, guard, ...) with 0 fail on every group; several groups were [degraded] or [not-installed] because this tree is not an initialized operator workspace. Healthy for a Brigade source checkout is exit 0 and 0 failed, not zero warnings.

Drive

Real commands from this repo, one per mapped feature. The full map is in features/README.md; drive the feature your change actually touched, not just the convenient one.

C=registry/skills/verify-brigade/control-brigade.py

# init + doctor wiring
$C doctor-target --target "$TARGET"

# work verification receipts (returns the receipt id and status)
$C work-verify --target "$TARGET" --capture verify-brigade

# Grok Bot connector pack lifecycle (implementation-worker is the worker pack)
$C grokbot-pack-setup  --target "$TARGET" --id implementation-worker
$C grokbot-pack-setup  --target "$TARGET" --id implementation-worker --apply
$C grokbot-pack-doctor --target "$TARGET" --id implementation-worker
$C grokbot-pack-canary --target "$TARGET" --id implementation-worker
$C grokbot-pack-remove --target "$TARGET" --id implementation-worker

# feed manifest validation and queue projection
$C grokbot-feed   --target "$TARGET" --sample
$C grokbot-status --target "$TARGET"

# handoff inbox lint
$C handoff-lint --target "$TARGET" --content-guard

Read the exit code, not the prose:

| exit | meaning | |---|---| | 0 | the drive ran and the observation is what a healthy rig produces | | 1 | the helper itself failed (no Brigade, unsafe path, bad target) | | 2 | usage error | | 3 | the drive ran fine, but the observation is a failure |

Stable handles to assert on, in order of preference: the JSON keys the helper normalizes (run_id, status, summary.failed, checks[].status, valid, reason), then the receipt directory under $TARGET/.brigade/work/verify-runs/<run-id>/. Do not grep the human prose; it changes.

Checkout-level focused gates for a change in this repo (no full suite). ./scripts/verify-focused itself runs ruff, ruff format --check, mypy, version-sync, the managed and template-profile snapshots, then the named pytest selectors. The three lint/type pieces can also be run alone:

./scripts/verify-focused tests/test_skills_cmd.py tests/test_ci_workflow.py
.venv/bin/ruff check src/brigade
.venv/bin/ruff format --check src/brigade
.venv/bin/mypy

Receipted form — same focused command, recorded as a work-verify receipt (brigade work verify run --help lists --argv-json, --capture, and --json; --help itself exits 0):

.venv/bin/brigade work verify run --target . \
  --argv-json '["./scripts/verify-focused","tests/test_skills_cmd.py","tests/test_ci_workflow.py"]' \
  --capture brigade-work

--command and --argv-json receipts are audit-only. Do not pass --no-reuse to the full ./scripts/verify gate. Do not run ./scripts/verify-fast or the full suite from this skill.

Evidence

registry/skills/verify-brigade/control-brigade.py evidence --target "$TARGET" --label <what-you-proved>

Writes .brigade/verification-evidence/<stamp>-<label>/ in the checkout and prints the path as evidence_dir. It contains captures/ (every command the helper ran, with argv, exit code, stdout, stderr, duration), target-brigade/work/verify-runs/ (the real receipts Brigade wrote), and manifest.json. That directory is outside the state root, so cleanup cannot reach it.

Proof standards for this repo:

  • Drive the CLI path a user runs. Do not import brigade.* in Python and call the function; a passing unit test is not a proof that the command works.
  • Capture the action and the resulting state. A work-verify proof is the command record and the receipt directory it names.
  • Verify the side effect on disk, not just stdout. grokbot-pack-setup --apply claims it wrote .brigade/grokbot/packs/<id>.json; look at the file.
  • Preview modes here are genuinely non-mutating, but check rather than trust: grokbot-pack-setup without --apply and grokbot-pack-remove without --apply print a writes/paths list and touch nothing, and grokbot-feed validates without enqueueing. Confirm by diffing $TARGET/.brigade/ before and after.
  • No mocks. Every command above hits the real CLI. The one boundary that is genuinely absent is a running Grok Bot listener, and the skill reads its absence as data rather than faking it.

Checkout work verify receipts live at .brigade/work/verify-runs/<run-id>/receipt.json. Cite the run_id in the PR body (work-verify receipt: <run-id>). A passing receipt has "status": "completed" and commands[].exit_code of 0. See docs/receipt-schemas.md and the citation paragraph at the end of this skill.

Cleanup

registry/skills/verify-brigade/control-brigade.py cleanup --dry-run   # see it first
registry/skills/verify-brigade/control-brigade.py cleanup

Cleanup removes only paths recorded by new-target and only when they sit under <state-root>/targets/; anything else is skipped with a reason. It never kills processes by name, and it never removes an evidence directory. Use --target to drop one target, --keep-captures to leave the raw command records in the state root.

After cleanup, confirm the proof survived:

ls .brigade/verification-evidence/<stamp>-<label>/manifest.json

.venv/ is gitignored (.gitignore line .venv/). Never commit .brigade/ — the root .gitignore lists .brigade/ and .brigade/work/ among the ignored paths. Evidence under .brigade/verification-evidence/ is also gitignored; copy a receipt id into the PR body instead of adding the directory. After a checkout-level verify, leave .venv/ in place for the next drive; remove it only when you are done with the tree (rm -rf .venv). Do not git add either tree.

Helpers

control-brigade.py is the only helper. It is executable, stdlib-only, and prints one JSON object per call.

registry/skills/verify-brigade/control-brigade.py --help

Subcommands: doctor, new-target, init, doctor-target, work-verify, grokbot-pack-setup, grokbot-pack-doctor, grokbot-pack-canary, grokbot-pack-remove, grokbot-feed, grokbot-status, handoff-lint, evidence, cleanup.

Global flags: --brigade "<command>" to drive a different Brigade build (for example --brigade "$(command -v python3) -m brigade"), --root <dir> to isolate the state root when two runs go at once (a directory under $TMPDIR, not $TMPDIR itself), --timeout <s> per call.

Every subcommand that writes accepts --dry-run, which reports the command it skipped and mutates nothing: new-target, init, work-verify, grokbot-feed --sample, evidence, cleanup, and grokbot-pack-setup/grokbot-pack-remove (there it forces preview even with --apply). The dry-run envelope carries "dry_run": true and a would_run, would_remove, or would_copy list.

tests/test_verify_brigade_skill.py runs new-target, doctor-target, work-verify, and cleanup in a pytest tmp_path, and asserts the path refusals (including a symlink planted at the default state root), the unwritable-root JSON envelope, and the 0600/0700 permissions, so CI fails if this helper stops working or stops guarding.

Reporting the proof

Do not claim a Brigade behavior without the receipt. When a change is done, route the repo's own gate through Brigade once:

brigade work verify run --target . \
  --argv-json '["./scripts/verify-focused","<pytest-selector>"]' \
  --capture brigade-work

Then paste the run_id, the status, and the evidence_dir from this skill.

That receipt is proof for a human reader, not a scored trial. --command and --argv-json receipts are audit-only; only --manifest <id> produces a receipt the outcome ratchet can score. Each --capture run prints which one it was. See docs/outcome-scoring.md.

Checkout receipts from brigade work verify run --target . land at:

.brigade/work/verify-runs/<run-id>/receipt.json

Cite the run_id in the PR body as a single line, for example work-verify receipt: <run-id>. Read it back with brigade work verify show <run-id> --json. A passing receipt (docs/receipt-schemas.md, brigade.work_verify_receipt schema_version 2) has "status": "completed", a run_id shaped <YYYYMMDD>-<HHMMSS>-work-verify-<hex>, commands[].exit_code of 0, and the identity tuple baseline_commit / tree_fingerprint / changes_patch_sha256. Failures still write a receipt ("status": "failed"); that is the ledger signal, not a missing file.
