85%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is exceptionally actionable, with executable commands, exact flags, explicit exit codes, thresholds, and validation/feedback loops at every stage of a clearly sequenced workflow. Its main weakness is organization: advanced modes (paired runs, matrix descriptors, caching protocol, performance comparison) are inlined rather than split into reference files, which both lengthens SKILL.md and obscures the simple prepare-run-compare-report path.
Suggestions
Move the advanced material — the paired-sandbox run semantics, the matrix treatment descriptor schema and its workflow, and the baseline-cache provenance protocol — into reference files (e.g., references/paired-runs.md, references/matrix.md, references/baseline-cache.md) and keep a short core path (prepare → run base → validate → run candidate → compare → report) plus brief signed pointers in SKILL.md.
Deduplicate the cache-validity rules: the stamping, verification, and 'never cache unstamped runs' requirements each appear in multiple sections; state them once in the caching reference and refer back to it.
Add a short 'When to use which mode' decision list (simple PR → plain two-run flow; rule-only PR → incremental scoped run; multiple PRs sharing a base → matrix) so readers can locate the relevant branch without reading all variants.

Conciseness | The body assumes Claude's competence throughout (e.g., "Require `VERCEL_OIDC_TOKEN` or `VERCEL_TOKEN` with `VERCEL_TEAM_ID`..."; "Run from `packages/evals`. The default corpus contains the 2,000 highest-ranked repositories...") with no explanation of known concepts. Cache-validity invariants are restated across sections ("Never cache an older unstamped run", the provenance/verify paragraphs, and "A cached baseline must still pass the streaming validator before reuse"), which is trimmable redundancy, placing it at anchor 4 rather than the every-token-earns-its-place anchor 5. | 4 / 5 |
Actionability | Fully executable guidance: concrete shell commands with exact flags and paths (e.g., the paired eval command with `--paired-baseline-output`, `--paired-execution sequential`), a complete JSON descriptor schema, enumerated exit codes ("`0`: diagnostics match, `1`: ... `2`: inputs are incomplete or invalid"), and specific thresholds ("flags an individual project only when it is at least 50% and two seconds slower"). Copy-paste ready and covers the common cases, matching the anchor-5 example. | 5 / 5 |
Workflow Clarity | A clear Prepare → Run both revisions → Compare → Report sequence with pervasive explicit validation checkpoints and feedback loops appropriate to this batch operation: "Before the candidate run, stream-validate every baseline record", "If the baseline command exits non-zero or the check fails, inspect its failed records and stop", the 200→50→10 retry ladder, and "Any nonzero paired evaluator run still makes both output artifacts invalid and non-reusable; discard them". This satisfies the destructive/batch validation requirement and matches the anchor-5 feedback-loop example, not anchor 4 which allows minor validation gaps. | 5 / 5 |
Progressive Disclosure | Section headers exist and every referenced script path (baseline-cache-provenance.mjs, verify-matrix-artifact.mjs, compare-parity.mjs, compare-parity-performance.mjs, find-impacted-rules.mjs, build-parity-index.mjs, compare-parity-indexes.mjs, validate-parity-input.jq, and the test files) is real and invoked inline, but roughly 150 lines of advanced material (paired-sandbox internals, the matrix treatment descriptor schema, the baseline-cache provenance protocol, performance-comparator thresholds) is inlined in SKILL.md with no references/ split. This matches anchor 3 (content that should be separate is inline); not 4 because the main path is buried among advanced variants, and not 2 because structure is present and all references are clear and one level deep. | 3 / 5 |
