87%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured reference skill: lean table-driven body, concrete actionable test-authoring guidance, and textbook progressive disclosure into a single verified reference file. The only gap is workflow clarity — it is a lookup catalog, not a sequenced process with validation checkpoints.
Suggestions
Add a short explicit authoring workflow (e.g., 1. identify scenario in 'When to use,' 2. look up the field's test implication in the summary table, 3. pull the exact shape from references/manifest-matrix.md, 4. cross-check the Anti-patterns table) to give the lookup flow a clear sequence.
Include a validation checkpoint for the conformance path — e.g., 'assert manifest_version == 3 first, then per-field assertions' — so the implicit test-authoring flow has an explicit entry assertion.
Optionally add a minimal copy-paste manifest skeleton in the body (or a clearly signaled snippet in the reference) so a test author has a directly executable starting point without reassembling fields from the table.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and table-driven with purposeful framing (navigation pointers, distinctiveness vs sibling skills) rather than padding; it does not belabor concepts Claude already knows, so it matches the 'lean and efficient; every token earns its place' anchor. | 3 / 3 |
Actionability | Provides concrete, specific directives — exact field names, conceptual shapes ("array of { resources: [...], matches: [...] } objects"), per-field test implications, and an anti-patterns table with precise fixes ("Use chrome.storage.local," "Register synchronously at top level"); as an instruction-only reference skill, code absence in the body is not penalized per the scoring note, with executable shapes appropriately deferred to the reference. | 3 / 3 |
Workflow Clarity | Sections and tables are well-organized and support an implicit lookup flow (When-to-use → field table → reference), but there is no explicit multi-step sequence, validation checkpoint, or feedback loop, and the skill is too multi-faceted to qualify for the simple-skill auto-3; this fits 'sequence present but checkpoints missing or implicit' rather than the unclear level 1. | 2 / 3 |
Progressive Disclosure | Clear overview with inline summary tables that repeatedly and explicitly signal one-level-deep detail in references/manifest-matrix.md (verified to exist), with exact shapes, the full key matrix, and code appropriately split out; matches the 'clear overview with well-signaled one-level-deep references' anchor. | 3 / 3 |
