Semantic diff review with Jev
Experimental support for development agents. Use semantic evaluation where it adds value; use deterministic tools for mechanical checks.
Workflow
Read the shared protocol for evidence preparation, API use and interpretation. The client is bundled so this skill can be installed independently.
Inspect the exact diff, definitions, callers and relevant tests. Provide before/after snippets, verified locations and one explicit invariant per question. Include an insufficient-evidence option. Verify suspected findings with code inspection or a reproduction before issuing a review comment. Report the trigger, impact and location. Do not invent line numbers or label a vulnerability solely from a model score.
Synthetic example
Run from this skill directory:
python3 scripts/ask.py examples/request.json --dry-run
python3 scripts/ask.py examples/request.json
The expected category is violated. Investigate disagreement by examining context, questions and results; do not tune the example merely to force agreement. A synthetic example is a smoke check, not an accuracy benchmark.
