maintain skillA
maintain is agent-read markdown (skill) from garrytan/gbrain: Brain health checks: back-link enforcement, citation audit, filing validation, stale info detection, orphan pages, and benchmarks. Use when asked to check brain health, run maintenance, or audit quality..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Maintain Skill Periodic brain health checks and cleanup. ## Contract This skill guarantees: - All health dimensions are checked (stale, orphan, dead links, cross-refs, backlinks, citations, filing, tags) - Each issue found has a specific fix action - Back-link iron law is enforced - Citation format is validated against the standard - Results are reported with counts per dimension ## Phases ### Autonomous path (v0.36.4.0) — when you want to reach a target score If the user asks "get my brain to 90/100" or "fix what's broken", prefer the one-command loop over walking each dimension by hand: ```bash gbrain doctor --remediation-plan --json # preview what would run gbrain doctor --remediate --yes --target-score 90 --max-usd 5 ``` `--remediation-plan` prints a dependency-ordered list (sync before extract, embed after consolidate, etc.) with per-step `est_seconds` and `est_usd_cost`. `--remediate` walks the plan, submitting each step as a Minion job, re-checking score between every step. `--max-usd N` is a hard cost cap — submission refuses when the plan would exceed the cap (prevents synthesize loops from burning Anthropic credits unattended). …
