88%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.
A highly actionable, carefully sequenced workflow whose guidance is almost entirely non-obvious craft knowledge (attribution rules, null semantics, what not to report) rather than filler. Its main weaknesses are repetition of the same interpretive caveats across multiple sections and keeping all field-level detail inline instead of splitting it into a reference file for the report-writing step.
Suggestions
State the commitsWithOurWork null/gitUnavailable distinction once — either in the JSON schema comment or in the Step 3 bullets — and cross-reference it from the other location instead of re-explaining it three times.
Explain the 'spend belongs to a project, not a tool' rationale in one place: the JSON comment and the 'Don't add a where the spend went' section currently make the same argument in full.
Move the annotated JSON schema and the per-field report-writing guidance into a reference file (e.g. references/report-format.md) loaded at Step 3, keeping SKILL.md to the workflow itself.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient and dense with non-obvious domain guidance ('a Bash call carries no working directory, so a commit in a throwaway fixture repo under /tmp can't be told apart from one in the dev's project'), but noticeably above anchor 3 rather than at anchor 5: the commitsWithOurWork null-vs-gitUnavailable semantics are explained in the JSON comment, again under the commits-column bullet, and again in its own bullet; the ~90%-context-handling spend rationale likewise appears both in the JSON comment and in full in the 'Don't add a where the spend went' section. These repetitions could be consolidated without loss. | 4 / 5 |
Actionability | Fully executable end-to-end: exact miner invocation ('node <skill-dir>/scripts/mine-transcripts.mjs --days <N> [--repo <substr>] --html /tmp/cc-receipt.html'), explicit $ARGUMENTS parsing rules ('week' → 7, 'month' → 30, bare number → days, substring → --repo), exact output filenames ('~/claude-code-receipts-<since>-to-<until>.md') with dates sourced from the JSON, a complete annotated output schema, and a per-section report structure covering the common cases. | 5 / 5 |
Workflow Clarity | Six explicitly sequenced steps with interpretive validation checkpoints throughout: 'check totals.gitUnavailable before you say which' when totals.commitsWithOurWork is null, keep the miner's ordering ('top 12 by share of spend, biggest first... don't re-sort'), take since/until 'from the JSON — not from your own date arithmetic', and surface the project-name list before any sharing, with publication gated on explicit request. No destructive or batch operation is involved, so a validate-fix-retry loop is not applicable; every decision point that could produce a wrong report has an explicit branch. | 5 / 5 |
Progressive Disclosure | Good structure: the single bundle file (scripts/mine-transcripts.mjs, verified present) is referenced one level deep and clearly signaled ('ships alongside this SKILL.md, under scripts/'), and sections are well-organized per step. Not anchor 5: the ~150 lines of JSON field semantics plus report-writing/framing guidance are inline in SKILL.md; the schema semantics are only needed at Step 3, so a reference file loaded at that step would keep the SKILL.md body leaner — a minor organization gap rather than content that clearly 'should be separate.' | 4 / 5 |
