name: find
description: Retrieve the architecture decision records relevant to files, components, or a topic being worked on — callable at any point mid-task, not just at session start. Use unprompted before changing behavior that may already be decided (a locked choice, a convention, a rejected alternative). Invoked by `/os-adr:find`.
---
Find the ADRs relevant to what is being worked on. Retrieval is deterministic-first: run the
CLI, then apply judgment ONLY to the candidates it returns — never read/rank the full ADR
corpus yourself.
## 1. Run the deterministic CLI
```bash
ruby ${CLAUDE_PLUGIN_ROOT}/bin/adr-find --root <project-root> \
--paths <comma-separated file/dir paths being edited> \
--components <comma-separated component names> # optional
```
The CLI layers: frontmatter path/component matching → Accepted-only status filter →
one-hop Graphify graph expansion of the query paths (automatic when `graphify-out/graph.json`
exists; silently skipped otherwise). Add `--all-statuses` only when history matters (e.g.
"why was X superseded?").
## 2. Judge the candidate set
Read the returned candidate files (they are few) and decide which actually bear on the task.
`matched_on` tells you why each surfaced (`path`, `graph`, `component`). Prefer direct path
matches; treat `graph` matches as "nearby decisions worth a look".
## 3. Act on what you find
- If the in-progress change **conflicts** with an Accepted ADR: stop, surface the specific ADR
(ID + title + the constraint), and either adjust the approach or propose superseding it via
`/os-adr:create` with `supersedes`.
- If a candidate merely informs the work, cite it and continue.
- If the CLI returns nothing, say so — do not fall back to sweeping `docs/adr/` unless the user
asks; an empty result usually means no decision governs those paths (or `affected-paths`
frontmatter is missing on older ADRs — worth mentioning once).
