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 operational skill body: it teaches only sandbox-engine specifics Claude cannot know, gives exact knobs and failure-handling loops, and includes explicit validation discipline (trust the verdict line, never raw status). The two soft spots are rhetorical asides that add tokens without guidance, and a ~90-line single-file layout whose fast-path table and engine internals could be offloaded to a one-level-deep reference file.
Suggestions
Trim rhetorical asides ("This is the whole point of the engine…", "(the discipline that matters)", "If it still fails, that is a real wall") to cut tokens without losing any operational guidance.
Move the platform fast-path table and the curl_cffi/headless escalation-ladder internals into a references/ file (e.g. references/platforms.md), keeping SKILL.md a lean overview with a clearly signaled one-level-deep pointer.
Fold the duplicated 'trust the verdict' guidance in R2 and R6 into one place to avoid restating the validation rule.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense with engine-specific operational detail Claude cannot know elsewhere (verdict lines, stop_reason semantics, escalation ladder, RoE gating) — no filler explanations of concepts Claude already knows. However, rhetorical asides could be trimmed: quotes: "This is the whole point of the engine: the cheap path failing is the *start* of escalation, not permission to stop", "(the discipline that matters)", "If it still fails, that is a real wall". Not a 3: there are no padded sections or unnecessary concept explanations; not a 5: the editorializing flourishes are tokens that don't instruct. | 4 / 5 |
Actionability | Concrete, executable guidance throughout. Quotes: "Always pass a `selector` (e.g. `article`, `#content`, `[class*='product']`)", "Retry once with `device=\"mobile\"`", "`web_search(\"site:reddit.com <topic>\")` first, then `web_fetch` the result URLs", plus a fast-path table giving exact URL forms for Reddit, X, YouTube, GitHub, npm, and PyPI covering the common cases. Not a 4: for the user-driven parts (the only knobs being selector and device), the instructions leave no gaps. Code absence is not penalized per the instruction-only scoring note. | 5 / 5 |
Workflow Clarity | Clear sequenced workflow with explicit validation checkpoints and feedback loops. Quotes: "Typical flow: web_search to find a URL → web_fetch to read it", "Trust the tool's verdict / [web_fetch OK|FAILED] line, never a raw status", and the R6 failure loop: terminal stop_reasons (auth_required, not_found) mean move on, everything else gets a retry with device="mobile"/a precise selector, and "rate_limited (429) is NOT terminal — back off, then retry". Not a 4: validation and error-recovery checkpoints are explicit, not merely present. | 5 / 5 |
Progressive Disclosure | Single-file skill (no references/, scripts/, or assets/ exist) with well-organized sections: tool overview, escalation ladder, verdict validation, failure handling, RoE boundary, and a fast-path table. Quotes: section headers "How web_fetch escalates", "R2 — HTTP 200 is NOT success", "R6 — a give-up is NOT exhaustion", "Platform fast-paths". Not a 5: the body is ~90 lines (over the 50-line simple-skill threshold) with all detail — the platform fast-path table and escalation-ladder internals border on reference material that could live one level deep. Not a 3: structure is clear and nothing is buried or misplaced for its size. | 4 / 5 |
