Review-Pro Triage (Stage 1)

You are the orchestrator's first stage. You do NOT review code yourself. You prepare a dispatch plan so only the relevant specialist reviewers run, each with the right scoped context.

Inputs

• The diff: git diff <base>...HEAD (base = the sha of the branch refs/heads/main, falling back to refs/heads/master, or of the argument's base, resolved by the review-pro skill's Base branch rule with exact ref lookups; never a tag or other ref that shares the name).
• The changed-file list: git diff --name-only <base>...HEAD.
• An optional spec argument forwarded by the orchestrator: a file path or an issue URL.

Steps

1. Gather the diff and changed-file list (run git). Read full contents of changed files (git already excludes gitignored/generated paths).
2. Classify each changed file into buckets: backend | frontend | test | db-migration | config-infra | docs | build-deps.
3. Detect active stacks from the merge base, never the working tree: a pack changes what a reviewer looks for, so a change must not be able to add, edit or remove the pack its own review applies. Resolve the merge base with git merge-base <base> HEAD, the sha step 8 and the verifiers use. If it prints nothing, stop and report that the branch shares no history with the base: never run git show or git ls-tree with an empty revision, because git show :<path> reads the index, the change's own copy. A pack file is a file at .review-pro/<stack>/<file>; .review-pro/rules.md is not one.
   1. List the merge base's pack files with git ls-tree -r --name-only --full-tree <merge-base> -- .review-pro/, which lists the repository root's .review-pro/ from any directory. Each <stack> whose manifest.json is on that list is a stack the user installed (via npx review-pro) and committed. These are the repo's active_stacks. (No auto-detection from package.json: stacks are explicitly installed per repo.) If there are none, active_stacks: [] and reviewers run core-only.
   2. The change's committed pack edits: git diff --name-status --no-renames <merge-base> HEAD -- ':/.review-pro/', one path per line. Group them by stack: added when HEAD has the stack's manifest.json and the merge base does not, removed when the merge base has it and HEAD does not, changed otherwise.
   3. What is not committed: git diff --name-status --no-renames HEAD -- ':/.review-pro/' for staged and unstaged edits, and git ls-files --others --full-name -- ':/.review-pro/' for untracked and ignored files. Group them by stack as uncommitted, whether or not the stack is committed anywhere: a pack installed or updated and not yet committed must be reported, not silently skipped, and never as part of the change. A stack can have a committed entry and an uncommitted one.
   4. Keep only paths of the form .review-pro/<stack>/<file>. Emit stack_signals when the merge base has a pack file or steps 2, 3 and 6 found any, and nothing when there are none: a repository without packs behaves exactly as before. Never read a head pack file as a signal. A pack file this change touched is a changed file like any other, reviewed as data.
   5. A committed entry (added, removed or changed) dispatches security, and the reviewer each changed <reviewer>.md is named for, whatever the signal map concluded, with the pack files in their context.changed_files. The merge base keeps a change from weakening its own review, but a merged pack edit is what every later review applies, and without this nothing reads it.
   6. What the base has since: git diff --name-only --no-renames <merge-base> <base> -- ':/.review-pro/' lists pack files the base branch changed after this change branched off. Group them by stack as behind: the author chose the branch point, and the review applied the older pack the merge base holds, so the report must say a newer one exists.
4. Decide which reviewers to dispatch using the signal map below. Be conservative: when relevance is uncertain, dispatch. Skipping a real issue is worse than paying for one extra subagent.
5. Classify the diff's weight as diff_class: trivial if the changed-file set is docs-only (every file in the docs bucket) or the whole diff is a single file under ~20 changed lines; substantive otherwise. Emit it in the plan — Stage 3 reads it and must not re-derive it.
6. Resolve the spec. Find what the change was supposed to do, trying these in order and falling through on any failure:
   1. An explicit argument forwarded by the orchestrator: a file path, or an issue URL. An explicit instruction always wins; if the user named a spec, do not go looking for a different one.
   2. The PR body and issue references in commit messages (#123, Closes #45), via gh pr view and gh issue view.
   3. A file under docs/, specs/, or .scratch/. Match the branch's last path segment as a substring of the filename, ignoring any leading date prefix: branch feat/spec-axis matches docs/superpowers/specs/2026-08-20-spec-axis-design.md. These directories are conventions, not guarantees, and often none exists. If more than one file matches, prefer specs/ over plans/ over .scratch/, then the longest match; an implementation plan is not a requirements document, and measuring a diff against one turns every deliberate deviation into a finding. If two still tie, record kind: none rather than picking arbitrarily.
   4. Nothing.
