Brain

What it does

When your agent uses it

• You want to know what your brain has captured about your own architecture
• Conventions (e.g
• What do I know about
• Check my knowledge base

Example prompts

• “what does my system map say about the proxy”
• “why did I pick Apache-2.0”
• “s my deploy runbook”
• “/brain”

Requirements

• Compatibility (from SKILL.md): Designed for Claude Code; ships with the bobs-big-brain (governed-brain) plugin, which auto-wires the governed-brain MCP server. Works in both modes: local (in-process, needs qmd on PATH) and team (proxies to your team brain when TEAMKB_API_URL is set). Same brain_search either way.
• Pre-approved tools (allowed-tools): mcp__governed-brain__brain_search

Workflow steps

3 steps, taken from the step headings in SKILL.md.

1. 1Search the governed corpus
2. 2Answer ONLY from the cited results
3. 3Handle an empty result honestly

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • mcp__governed-brain__brain_search

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • pnpm

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Links to these hosts (documentation or services it may open):

  • github.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

• Compatibility

  Designed for Claude Code; ships with the bobs-big-brain (governed-brain) plugin, which auto-wires the governed-brain MCP server. Works in both modes: local (in-process, needs qmd on PATH) and team (proxies to your team brain when TEAMKB_API_URL is set). Same brain_search either way.

  From compatibility in the SKILL.md frontmatter.

Context cost

Brain loads about 1.9k tokens when it runs. Until then it costs about 132 tokens; SKILL.md has 741 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~132

When it runs · the whole SKILL.md, loaded when a task matches

~1.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Answers questions about your own systems, notes, decisions, runbooks, and conventions from your governed knowledge brain, returning a qmd:// citation for every claim — receipts, not recall. Use when you want to know what your brain has captured about your own architecture, infrastructure, decisions, or conventions (e.g. "what does my system map say about the proxy", "why did I pick Apache-2.0", "what's my deploy runbook"). Trigger with "/brain", "ask the brain", "what do I know about", or "check my knowledge base".

/brain what does my system map say about the proxy?

→ The proxy is the single ingress; it reverse-proxies each domain to its service
  and must be reloaded, not restarted, after edits (qmd://kb-curated/system-map.md).

Sources:
- qmd://kb-curated/system-map.md

/brain what is my refund policy?

→ The brain has nothing governed on a refund policy. I won't guess from general
  knowledge. If this should be in your brain, capture it with /brain-save.
