73%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.
An exceptionally actionable and well-sequenced operational skill: every command, flag, path, and error-recovery loop needed to run the eval pipeline is spelled out, and validation checkpoints exist at each phase. Its two real weaknesses are structural — the referenced `run-eval.ts` script is missing from the bundle entirely, and significant internal duplication plus inlined reference material make the file longer than the content justifies.
Suggestions
Ship `run-eval.ts` in a `scripts/` directory (or replace the dependency with inline instructions) — the skill's core command currently points at a file that does not exist in the bundle.
Move the scoring schemas, artifact export layout, and monitoring snippets into a `references/` file (e.g. SCORING.md, ARTIFACTS.md) with clearly signaled one-level-deep links, keeping SKILL.md as an overview.
Deduplicate: merge the "Commands" section into "Proven Working Script", collapse the triple pipeline description (How It Works / Session Flow / Phase Details) into one, and drop or archive the dated "Proven Results" metrics.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense with genuinely non-obvious operational facts (sandbox paths, SDK version, heredoc 400 errors, snapshot semantics) and assumes Claude's competence, but it duplicates itself: the same four `bun run` commands appear in both "Proven Working Script" and "Commands", the 3-phase pipeline is described three times, and facts like the snapshot-stop behavior and v2-beta 404 repeat across "Key Discoveries", "DO NOT", and "Known Limitations". The dated "Proven Results (2026-03-10)" metrics table is padding that could be cut. | 3 / 5 |
Actionability | Guidance is copy-paste ready throughout: exact invocations with every CLI flag and default, the scenario JSON format with required fields, the haiku scoring JSON schemas, prerequisite setup commands, and monitoring snippets with literal paths — the common cases are fully covered. | 5 / 5 |
Workflow Clarity | The multi-step pipeline is explicitly sequenced (17-step "How It Works" plus a per-scenario flow diagram) with validation at every checkpoint: haiku structured scoring after each phase, 20s polling during builds, a snapshot restore point before verify/deploy, a verify feedback loop (fix → restart → re-verify), deploy retry up to 3 attempts, and crash-safe incremental result writing. | 5 / 5 |
Progressive Disclosure | Scored against the actual bundle: besides SKILL.md there are no reference, script, or asset files, yet the body's central command references `.claude/skills/benchmark-sandbox/run-eval.ts`, which does not exist in the bundle. Content that clearly belongs in separate files — three scoring schemas, the artifact export layout, monitoring code, and the dated results tables — is inlined in a 387-line monolithic SKILL.md, matching the "content that clearly belongs in separate files is inlined" anchor rather than a 3 (which presumes valid, working references). | 2 / 5 |
