maintain

maintain is a skill for Claude Code, Codex from cyberbird2048/gbrainmcp-clean. It costs 44 tokens per session (3,833 once invoked), scanned A, a copy of maintain, MIT.

A maintenance workflow for a GBrain knowledge base, which is a collection of linked research and project pages. It checks page freshness, links, citations, filing, tags, and related quality issues.

In plain words
What is it for?
For running health checks, finding orphan pages and dead links, checking citations and cross-references, and recording a specific fix for each issue.
Why use it?
It finds stale, isolated, incorrectly linked, or poorly documented pages before they make the knowledge base harder to trust and use.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

maintain scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

86% identical to maintain — 135 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 403 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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

  1. Run health check. Check gbrain health to get the dashboard.
  2. Check each dimension:

Stale pages

Pages where compiled_truth is older than the latest timeline entry. The assessment hasn't been updated to reflect recent evidence.

  • Check the health output for stale page count
  • For each stale page: read the page from gbrain, review timeline, determine if compiled_truth needs rewriting

Orphan pages

Pages with zero inbound links. Nobody references them.

  • Review orphans: are they genuinely isolated or just missing links?
  • Add links in gbrain from related pages or flag for deletion

Dead links

Links pointing to pages that don't exist.

  • Remove dead links in gbrain

Missing cross-references

Pages that mention entity names but don't have formal links.

  • Read compiled_truth from gbrain, extract entity mentions, create links in gbrain

Link graph extraction

If link_count is 0 or low relative to page_count, run batch extraction:

gbrain extract links --dir ~/brain

This scans all markdown files for entity references, See Also sections, and frontmatter fields, then creates typed links in the database.

Timeline extraction

If timeline_entry_count is 0, extract structured timeline from markdown:

gbrain extract timeline --dir ~/brain

Dream cycle (v0.23): synthesize + patterns

gbrain dream runs the full 8-phase maintenance cycle:

lint -> backlinks -> sync -> synthesize -> extract -> patterns -> embed -> orphans

The two new phases consolidate yesterday's conversations into long-term memory:

Synthesize phase: reads transcripts from dream.synthesize.session_corpus_dir, runs a cheap Haiku verdict (cached in dream_verdicts) to filter routine ops sessions, then fans out one Sonnet subagent per worth-processing transcript. Each subagent writes reflections (wiki/personal/reflections/...), originals (wiki/originals/ideas/...), and people timeline entries. The orchestrator collects the slugs from subagent_tool_executions (NOT pages.updated_at — that would pick up unrelated writes) and reverse-renders each new page from DB → markdown on disk.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
