open-brain-server: Skill for Claude Code

.claude/skills/brain-health/SKILL.md

brain-health is a skill for Claude Code from Bobby-cell-commits/open-brain-server. It costs 218 tokens per session (5,903 once invoked), scanned A, original, MIT.

A command that produces a scored health report for Open Brain, a knowledge graph that connects stored information. It checks themes, connections, duplicates, stale items, and other graph conditions over a chosen period.

In plain words
What is it for?
Use it to inspect graph structure, theme activity, duplicate pressure, outdated data, synthesis quality, and changes across reporting periods.
Why use it?
It shows whether the stored knowledge is well connected, maintained, and useful over time.

This is Bobby-cell-commits/open-brain-server's own configuration. It tells Claude Code how to work on open-brain-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything open-brain-server configures →

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

brain-health 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 10d 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.

/brain-health — Knowledge Graph Health Report

Produce a rubric-scored health report for Open Brain's knowledge graph: theme attention, graph structure, maintenance health, entity landscape, and serendipity picks. Cross-run memory for longitudinal tracking.

Arguments

Parse from user message:

  • days: Integer, default 7. The reporting period in days. Usage: /brain-health or /brain-health 14.

Set N = days value for all tool calls below. Set TODAY = current date in YYYY-MM-DD format.

Phase 1: Data Gathering

Call all 12 MCP tools in parallel. There are no dependencies between them.

Parallel calls:

  1. analyze(type="themes") — theme attention map: velocity, lifecycle, centroid drift

  2. thought_stats(days=N) — current period breakdown (type, theme, topics, people)

  3. thought_stats(days=N*2) — double-window stats (subtract current to derive prior period)

  4. analyze(type="density") — graph connectivity at 0.70/0.75/0.80/0.85 thresholds

  5. analyze(type="hubs", min_connections=5) — cluster nuclei

  6. analyze(type="co_occurrence") — usage-driven edges, session stats, decay

  7. dedup_review(limit=30) — near-dupe zone histogram + candidate pairs

  8. review_stale(action="list") — pending Tier 3 archival candidates

  9. list_entities(entity_type="tool", min_thoughts=3) — tool frequency landscape

  10. list_entities(entity_type="person", min_thoughts=3) — people frequency landscape

  11. serendipity_digest() — forgotten high-quality thoughts

  12. list_thoughts(type="synthesis", days=N*2, min_quality=0, limit=50) — Dream Phase C synthesis thoughts for health assessment

  13. Glob research/brain-health/*.md, sort filenames descending, skip any file matching TODAY's date, take the first match. Read its YAML frontmatter and extract the findings array. If no prior report exists or the prior report has no findings array, set prior_findings to an empty list.

  14. Read research/brain-health/BASELINE.md (if it exists). Parse YAML to extract suppress and force lists. If the file does not exist, set both lists to empty.

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.

brain-health is a skill published in the GitHub repository Bobby-cell-commits/open-brain-server (8 stars, last pushed 4mo ago), licensed MIT. It adds 218 tokens to every session and 5,903 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
