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 well-crafted, actionable skill body: precise field semantics, a staleness-verification ladder, explicit fallback behavior, and two concrete worked examples. The only real cost is repetition of the re-read-fresh rule, which slightly inflates length without adding new guidance.
Suggestions
Conciseness: state the 'read the file fresh every deictic turn' rule once (the section is enough) and drop its restatement in the two examples' step 1 and closing lines — the frontmatter already carries it.
Conciseness: the selection-field bullets repeat information ('this is the canonical handle — match against the source line, not the rendered DOM') that can be compressed to one line, since tagName/text already make the distinction clear.
Progressive disclosure: if the skill grows, move the annotated field reference and the two worked examples into a single reference file linked from a short SKILL.md overview.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is efficient — no padding, no explanations of concepts Claude already knows, and every section (field semantics, staleness rules, when/when-not) adds skill-specific knowledge. Minor over-explanation remains: the 're-read on every deictic turn' point is stated in the frontmatter, restated in its own section, and again in the examples' step 1, so it could be trimmed — matching the 'efficient with minor instances of over-explanation' anchor. | 4 / 5 |
Actionability | Fully actionable: the exact path, the tool to use ('Use the `Read` tool. The file is JSON.'), a complete annotated example payload, per-field usage rules (0-based pageIndex vs 1-based pageNumber), and two worked examples with numbered steps. As an instruction-only skill the guidance is copy-paste-ready without code. | 5 / 5 |
Workflow Clarity | Both worked examples are clearly sequenced (read current.json → check staleness → read pagePath → locate page/element → edit) with an explicit validation checkpoint (the fresh/5-minute/hours staleness ladder keyed to `updatedAt`), plus explicit fallback and error-recovery branches for missing file, null selection, and stale data. | 5 / 5 |
Progressive Disclosure | No bundle files exist, and everything present belongs inline for a skill of this scope — the structure (when to use / when NOT to use / field reference / examples) is well organized with no content that clearly belongs in a separate file. It stops short of the 5 anchor because the body runs ~110 lines; the annotated field reference and the two examples could be tightened or split were the skill to grow. | 4 / 5 |
