75%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 dense, genuinely useful reference: precise decomposition formulas with verification identities, a materiality framework, narrative templates with anti-patterns, and reconciliation-checked waterfall formats. Weaknesses are modest — a few concept re-explanations Claude doesn't need, two decompositions lacking worked examples, and no explicit end-to-end workflow tying the sections together.
Suggestions
Add a short end-to-end workflow section (identify variances → apply materiality thresholds → decompose → write narrative → present waterfall) so the operating sequence is explicit rather than implied by section order.
Add a worked numeric example for the rate/mix decomposition (like the price/volume example) and formulate the headcount timing and attrition variances so every decomposition technique is executable.
Trim concepts Claude already knows — the waterfall/bridge chart definition, the forecast-accuracy formula, and the MAPE acronym expansion — or move detailed methodology (waterfall tables, forecast accuracy) into reference files to slim the SKILL.md body.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The bulk is lean, high-value reference material (formulas, threshold tables, templates, anti-patterns), but a few passages explain concepts Claude already knows — "A waterfall (or bridge) chart shows how you get from one value to another..." and "MAPE (Mean Absolute Percentage Error) = ..." — so it matches the 'efficient; minor instances of over-explanation that could be trimmed' anchor rather than the top one. | 4 / 5 |
Actionability | Provides concrete formulas ("Volume Effect = (Actual Volume - Budget Volume) x Budget Price"), a fully worked $500K→$528K example, a copy-paste narrative template, and a text-waterfall format. Not 5: the rate/mix example asserts "Mix effect explains 2pp of margin compression" without showing the computation, and headcount timing/attrition variances are named but not formulated — minor gaps in executable coverage. | 4 / 5 |
Workflow Clarity | Section ordering implies the sequence (decompose → apply materiality → write narrative → present waterfall), and explicit checkpoints are present ("Verification: Volume Effect + Price Effect = Total Variance", "Verify the waterfall reconciles (start + drivers = end)") plus a narrative quality checklist. Not 5: no explicit end-to-end step sequence ties the sections into a single stated workflow, leaving the operating order implicit. | 4 / 5 |
Progressive Disclosure | A well-organized single-file skill with clear, navigable section headers and content appropriate to a single reference document (no bundle files exist). Not 5: it is a full inline treatment rather than an overview with well-signaled references — detailed methodology such as the waterfall tables and forecast-accuracy analysis could be split into reference files to keep SKILL.md as a leaner overview. | 4 / 5 |
