name	skillpack-check
version	1.0.0
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).

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

Output format

    "checks": [
      { "name": "minions_migration", "status": "fail", "message": "MINIONS HALF-INSTALLED (partial migration: 0.11.0). Run: gbrain apply-migrations --yes" }

    "partial_count": 1,
    "stdout": "..."
  }
}

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.
