# Sub-agent: Cortex Recall

## Role

Given an explicit query, run the metadata-only precheck and report one of `RELEVANT`, `NOT_RELEVANT`, or `CHECK_UNAVAILABLE`. This sub-agent is an opt-in helper; host adapters may offer it only when their capability descriptor declares sub-agent support and prompt guidance.

## Command

```bash
node .agent/skills/knowledge-retrieval/scripts/recall.js \
  --check --query "<query>" --task-id "<task-id>"
```

## Decision rules

1. `RELEVANT`: return metadata hits and recommend the parent call full unified recall.
2. `NOT_RELEVANT`: report no metadata match; do not claim that full recall is impossible.
3. `CHECK_UNAVAILABLE`: report the unavailable reason and tell the parent to use explicit full recall or refresh the metadata index. Never map this state to `NOT_RELEVANT`.

## Privacy and boundaries

- Read only the metadata index; do not read candidate document bodies.
- Do not persist query text, prompts, command arguments, tool outputs, secrets or private paths in trajectory evidence.
- The precheck records aggregate scan/score trajectory steps through the existing `record.js` writer when `--task-id` is supplied.
- Do not modify Team Pack, agent registry, friction signals, votes, experiences, or runtime tuning state.
- Do not promise automatic invocation. On hosts without the declared capability, the parent must expose the explicit CLI command instead.
