Use when the user says "/backfill-feature", "backfill the ADR", "this feature has no ADR", "I need to document what's already there before I change it", or wants to capture an existing feature's architectural rationale and behaviour *before* modifying it. Reads the relevant code, drafts a reverse-engineered ADR (what is, why it probably looks like this) + Gherkin spec (current behaviour) + characterization tests that lock the current behaviour green. Hands off to /plan-change so the actual change can be layered on top of a documented, tested baseline.

Repository-grounded threat modeling that enumerates trust boundaries, assets, attacker capabilities, abuse paths, and mitigations, and writes a concise Markdown threat model. Trigger only when the user explicitly asks to threat model a codebase or path, enumerate threats/abuse paths, or perform AppSec threat modeling. Do not trigger for general architecture summaries, code review, or non-security design work.
