description: |
  Run `gbrain skillpack-check` to produce an agent-readable JSON health report
  for the gbrain install. Wraps `gbrain doctor` + `gbrain apply-migrations
  --list` so a host agent (your OpenClaw's morning-briefing, any OpenClaw cron)
  can see at a glance whether the skillpack needs attention.

  Use when the user asks "is gbrain healthy?", when a cron fires a morning
  check, or proactively when something seems off (jobs not running, brain
  not updating, autopilot silent).
triggers:
  - "skillpack check"
  - "is gbrain healthy"
  - "gbrain health"
  - "check the brain"
  - "is the brain working"
tools:
  - shell
mutating: false

Skillpack Check

Contract

Running `gbrain skillpack-check` returns a JSON report with:

• **`healthy`** (bool): true if no action needed.
• **`summary`** (string): one-line summary safe to quote in a briefing.
• **`actions`** (string[]): every remediation command. If non-empty, run them.
• **`doctor`**: full `gbrain doctor --fast --json` output (filesystem checks).
• **`migrations`**: applied/pending/partial counts from `apply-migrations --list`.

Exit code:

• `0` — healthy, nothing to do.
• `1` — action needed. Read `actions[]` and execute.
• `2` — could not determine (binary crash or missing subcommand). Investigate.

When to run

• **Daily cron** (e.g. your OpenClaw's `morning-briefing`): `gbrain skillpack-check --quiet`.

Exit code alone tells you if anything is wrong; surface a one-liner in the briefing only when exit != 0. No JSON noise in happy-path briefings.

• **On demand**: `gbrain skillpack-check` for the full JSON when debugging.
• **In a CI pipeline**: same pattern — exit code gates, JSON is the evidence.

What to do with the output

Happy path (`healthy: true`)

Surface the summary in the agent's output only if asked. Nothing else.

Action needed (`healthy: false`)

The `actions[]` array contains the commands to run, in order. Execute them:

for cmd in $(echo "$REPORT" | jq -r '.actions[]'); do
  eval "$cmd"
done

Common `actions[]` entries and what they mean:

• `gbrain apply-migrations --yes` — A migration is pending or half-finished.

Run this (it's idempotent). If it exits `status: "partial"`, the host has non-builtin cron handlers that need plugin registration — follow `skills/migrations/v0.11.0.md`.

• `gbrain embed --stale` — Embeddings are stale.
• `gbrain check-backlinks --fix` — Dead links or missing back-links.
• Free-text action (no `Run:` prefix in the source message) — agent judgment

needed. Quote it in the report for the user.

Determine failure (`exit 2`)

Treat as urgent. Probably means the gbrain binary is missing from `$PATH` or a required subcommand crashed. Check:

1. `which gbrain` returns a path 2. `gbrain --version` exits 0 3. `~/.gbrain/` is accessible

Anti-Patterns

• ❌ Running without `--quiet` in a cron that emails its output — you'll get

the full JSON blob in every daily email. Use `--quiet` in crons.

• ❌ Ignoring exit code 2. A crashed doctor is worse than a failing check

because you don't even know what's wrong.

• ❌ Running on every chat turn. Once per hour (or on user request) is plenty.
• ❌ Treating warnings as failures. Only `fail` status needs action;

`warn` is informational.

Output Format

The skill itself doesn't write files; it reports the CLI output verbatim to the user (or to the agent's briefing pipeline). One-line summary first, then the action list, then (only if relevant) the full JSON for debugging.
