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.
The body is a strong operational playbook: concrete commands, a well-sequenced iterative loop with explicit validation and revert behavior, and a real, well-signaled reference bundle. Its weaknesses are moderate verbosity (Overview and extraction steps duplicate workflow phases and reference-file content) and a couple of dangling or manual gaps that keep actionability and progressive disclosure just below excellent.
Suggestions
Trim the Overview bullet list and Step 1.2's inline grep/jq extraction commands, pointing to references/perf_tool_guide.md instead, since that guide already documents derive-session and sessions.overview.jsonl queries.
Remove or replace "or use script in skill directory" in Step 2.3 — no such script exists in the bundle — ideally with the concrete delta-calculation command (e.g., a jq expression comparing /tmp/baseline-metrics.json to /tmp/current-metrics.json).
Drop coaching notes like "Be patient - rushing leads to mistakes" and "Trust the data" style remarks that assume Claude needs behavioral reminders rather than instructions.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is mostly operational commands rather than concept explanation, but the Overview bullet list duplicates the Workflow phases, Step 1.2's grep/jq extraction restates content that lives in references/perf_tool_guide.md, and coaching lines like "Be patient - each perf run takes significant time... rushing leads to mistakes" add padding. This matches "mostly efficient but includes some unnecessary explanation or could be tightened" rather than the minor-trim level of 4. | 3 / 5 |
Actionability | Concrete executable guidance dominates: the exact runner command ("node development/perf-ci/run-ios-perf-detox-release.js"), full jq pipelines for metric extraction, a complete git branch/commit sequence, and a copy-paste perfMark TypeScript import. It stops short of 5 because "Calculate deltas manually or use script in skill directory" references a script that does not exist in the bundle, and the delta-comparison step is left as manual work. | 4 / 5 |
Workflow Clarity | The three-phase workflow has explicit validation at every iteration (Step 2.3 metric comparison against baseline), an explicit decision tree (SUCCESS >=10% time improvement -> stop; NO_IMPROVEMENT -> revert), a hard iteration cap of 10, and a genuine feedback loop of measure -> change -> verify -> keep/revert. This matches the anchor for clear sequencing with explicit validation and error-recovery loops. | 5 / 5 |
Progressive Disclosure | Both bundle files (references/template.md, references/perf_tool_guide.md) are real, one level deep, and clearly signaled in a dedicated References section, with template.md invoked at the right workflow point (Step 1.3). It is a 4 rather than 5 because derive-session usage and the sessions.overview.jsonl query are duplicated inline in SKILL.md despite being covered in perf_tool_guide.md, and a nonexistent "script in skill directory" is referenced. | 4 / 5 |
