# pin-query

Retrieve pins from the knowledge graph by calling `query(pinsDir, criteria)` from `lib/pins/query.ts`.

## Retrieval model

`query` calls `buildIndex()` on every invocation, scanning `pinsDir` in-memory. There is no `index.json` cache; every call performs a full directory scan and produces results directly.

The full entity set is always covered, including pins with no outgoing relations. Orphan pins remain findable by `type`, `tags`, or `source` — relation traversal is not required.

## Invocation

Run the bundled script from the deployed skill directory:

```bash
bun "${CLAUDE_SKILL_DIR}/scripts/query.ts" [--type <type>] [--tags <tag1,tag2>] [--source <source>]
```

`--tags` accepts a comma-separated list; all tags must match (AND semantics). Omit any flag to leave that field unrestricted. The script resolves the manifest automatically — if no manifest exists it prints the absent message and exits 0.

## Presenting results

Return matched slugs (`id`), `source_url` from the frontmatter, and a one-line summary to the caller. Report "no match" on an empty result set. Do not re-traverse the graph; the returned `Frontmatter` already carries `relations` if the caller needs to follow links.
