# Casefile

Use Casefile to maintain durable security investigation state across Codex turns. Prefer the MCP tools from the `casefile` server when they are available.

## Workflow

1. Check existing cases before opening a new one with `casefile_list` or `casefile_search`.
2. Open new leads with `casefile_add` as `hypothesis` or `investigating`.
3. Promote cases with `casefile_update` only after materially new evidence, proof, impact, blockers, remediation, or status changes.
4. Mark `confirmed` only when evidence and a PoC or repro are recorded.
5. Use `casefile_link` and `casefile_unlink` for exploit chains. Do not edit linked case IDs directly.
6. Use `casefile_report` only for confirmed or already reported cases.
7. Use `killed` for disproven, duplicate, or dead-end leads, and include evidence, blockers, next step, or assumptions explaining why.
