gaia-curation-review

Assess what a curation PR actually changes and return a structured recommendation. This skill is a read-only gate: it does not rebase, push, merge, force-push, or modify the PR.

Scope routing

Classify before reviewing:

• Intake-only PR or registry-for-review/ batch → route to /gaia-draft-curate.
• Canonical registry promotion/curation PR → continue below.
• Unrelated code or documentation PR → route to /review.

Workflow

1. Resolve PR and branch

For a PR number:

gh pr view <number> --json number,title,state,isDraft,headRefName,baseRefName,url,body,labels

For a branch, identify its base and remote. Fetch without changing the current branch:

git fetch origin <branch> <base>

Use a disposable worktree for checks so generated or ignored output cannot pollute the maintainer's working tree:

git worktree add --detach /tmp/gaia-review-<id> origin/<branch>

2. Establish the substantive diff

Run:

gaia dev diff origin/<branch>
git diff --check origin/<base>...origin/<branch>

gaia dev diff is the semantic summary, but it is not the only authority. Inspect source changes under:

• registry/nodes/;
• registry/named/;
• registry/suites/, when present;
• registry-for-review/, for routing only;
• docs/graph/, to confirm Class S regeneration when required.

Do not treat generated Class P files as the source of truth.

3. Compare claims with reality

Cross-check the PR title/body against the semantic diff. Flag every mismatch, including claimed skills absent from the diff, incorrect taxonomy/type language, unexpected removals, and claims that generated artifacts were updated when they were not.

4. Review canonical changes

For generic nodes:

• prerequisites exist and form a valid DAG;
• type and nomenclature match the current schema and CONTEXT.md;
• evidence is present with valid provenance;
• duplicate or overlapping generic mappings are explained;
• no existing generic or edge is removed without explicit justification.

For named skills:

• genericSkillRef resolves;
• contributor path and source identity agree;
• status/title or catalogRef requirements are satisfied;
• level/star changes are evidence-backed and timeline implications are understood;
• installable non-suite skills use a specific links.github blob/ URL, or explicitly declare non-installability;
• suite components and suite links point to their actual subpaths;
• terminology follows CONTEXT.md and does not introduce deprecated vocabulary.

For evidence:

• record evidence type, grade, source URL, and required numeric/provenance fields;
• distinguish evidence requiring live verification from evidence already validated;
• flag dead, bare-repository, tree/, duplicated, subjective, or unsupported evidence;
• do not use legacy Class A/B/C rules as the sole merge gate when the current evidence model provides more specific fields.

5. Check repository and generated-artifact scope

Confirm branch scope is allowed by the branch prefix and project rules. When canonical registry sources change, verify the PR includes required Class S artifacts under docs/graph/ or clearly explains why regeneration is deferred.

Check:

gaia dev validate
gaia dev docs --check
gaia dev test all

If named star levels or timelines changed, also run:

python3 scripts/validate_timelines.py

Record commands that could not run and why. Do not assume a successful command that was not executed.

6. Report severity and recommendation

Separate:

• Blocking failures — cannot merge safely;
• Warnings — follow-up recommended but not necessarily blocking;
• Evidence pending verification — requires live/source review;
• Checks run — exact commands and outcomes.

Use exactly one recommendation:

• MERGE SAFE — substantive checks pass; normal rebase/merge is a maintainer action;
• NEEDS REVIEW — list concrete blockers or unresolved questions;
• CLOSE — empty, already merged, or no substantive change;
• ROUTE — wrong workflow, with the destination skill.

Report format

## PR <number>: <title>

Branch: <head> → <base>
Status: <state>

### Scope classification
<canonical / intake / unrelated>

### What this changes
<generic nodes, named skills, edges, removals, generated artifacts>

### Claim vs diff
<mismatches or none>

### Blocking failures
<items or none>

### Warnings
<items or none>

### Evidence pending verification
<items or none>

### Checks run
<commands and outcomes>

### Recommendation
MERGE SAFE | NEEDS REVIEW | CLOSE | ROUTE

Never merge or alter the branch as part of this skill.
