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 WHEN you are about to make an architecture-level choice or change/replace an approach that already exists in the codebase (a persistence choice, a protocol, a library, a convention, an error-handling strategy) — a prior decision may already cover it. 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"why was X superseded?").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 an Accepted ADR covers the approach the in-progress change is altering or replacing, you
|
|
are **reversing a recorded decision** — and a reversal is itself a decision that must be
|
|
recorded, not just implemented. Surface the specific ADR (ID + title + the constraint), and
|
|
make the recording offer **explicit and direct** in your reply — state plainly "this reverses
|
|
ADR-NNNN; I'll record a superseding ADR via `/os-adr:create`" (or create it outright). Do not
|
|
bury the ADR as a parenthetical inside an option list; every path you offer that changes the
|
|
decided behavior must carry the explicit superseding-ADR step.
|
|
- 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).
