66%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 skill presents a well-sequenced diagnostic workflow with strong validation checkpoints and explicit handoff rules to related skills. It is weaker on token efficiency (repeated handoffs and overlapping source-discovery guidance) and actionability (abstract direction where a worked example or decomposition template would make the guidance executable).
Suggestions
State each $skill handoff once (at the step where it matters) and drop the "Related Skills" preamble to remove triplicated guidance and reduce token cost.
Add one compact worked example of a driver decomposition (e.g., a movement split into contribution shares with a reconciled residual) to make step 5's abstract sizing direction concrete and executable.
Move the explanation-mode catalog in step 4 and the source-access guardrail prose into a one-level-deep reference file so SKILL.md stays a lean overview.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is mostly efficient but carries repetition: the $gather-business-context handoff is stated three times ("Related Skills", step 1, step 4), and source-discovery guidance ("starting points, not stopping points") appears in both the configuration and step 2 sections, so it could be tightened without loss. | 3 / 5 |
Actionability | Some concrete guidance exists ("grain, aggregation logic, filters, joins, exclusions, freshness, lineage"; the four explanation modes), but much of the direction is abstract ("size each major driver with the strongest readily available evidence") with no worked example or query/decomposition template, so it reads as incomplete rather than fully executable guidance. | 3 / 5 |
Workflow Clarity | The six-step workflow is clearly sequenced with explicit validation gates ("Before explaining the movement, confirm...", "Do not search for causes until the size, timing, and scope of the pattern are verified") and a pre-handoff completeness checklist, matching the top anchor for sequence plus checkpoints. | 5 / 5 |
Progressive Disclosure | No bundle files exist and the body is well-sectioned with clear headers, so navigation is good; however, at ~130 lines monolithic, content such as the explanation-mode catalog and the source-access guardrail could live in one-level-deep reference files, which is a minor organization gap against the top anchor. | 4 / 5 |
