description: Route a second-brain request to its smallest playbook. Use when the user asks for canonical facts, raw evidence, generated-map navigation, Graphify output work, capture, compilation, migration, maintenance, or satellite content.

# Second Brain

Select one route before acting. The canonical wiki is current knowledge. Raw
evidence is immutable. Generated maps are navigation aids, not authority.

| Request | Read and use |
|---|---|
| Current fact, decision, context, proof, quote, exact canonical page, or raw evidence | `~/jstack/skills/querybrain/SKILL.md` |
| Query, path, explain, or browse an existing `graphify-out/graph.json` map | `~/.agents/skills/graphify/references/query.md` |
| Generate a wiki or HTML view from an existing map | `~/.agents/skills/graphify/references/exports.md` |
| Build, update, merge, name communities, repair, inspect health, or administer Graphify outputs | `~/.agents/skills/graphify/SKILL.md` |
| Capture new raw evidence | `~/jstack/skills/savetobrain/SKILL.md` |
| Compile, migrate, or maintain the second brain | `~/jstack/skills/brainwork/SKILL.md` |
| Satellite artifact | Use the native satellite route: thin canonical router, registered symlink, `docs/index.md`, selected artifact. |

For a request without an explicit map-navigation intent, use the retrieval
overlay route. If the overlay is not ready, use its exact repair command.

An existing generated `index.md` can help an agent select a topic or source to
open. It cannot support a factual answer by itself. Route any claim, decision,
or evidence check through the retrieval overlay and open the selected canonical
source; open exact raw evidence when required.

Done when the selected playbook completes its own acceptance check. Do not load
the full Graphify playbook for overlay retrieval or existing-map navigation.

| `querybrain` | The request needs current knowledge or evidence. |
| `brainwork` | The request needs capture, compilation, migration, or maintenance. |
