92%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.
Excellent operational content: concrete executable tool invocations, three well-sequenced workflows with explicit verification checkpoints, decision trees for error recovery, and a clear security/anti-bot policy. The only weakness is minor redundancy between the Iron Rules recap and earlier sections, which costs a few tokens without adding new information.
Suggestions
Trim the Iron Rules section to rules not already stated verbatim earlier, or fold them into the relevant sections, to remove repetition.
Replace the motivational framing ("Screenshots are a debugging superpower", "the single most common failure mode") with terse imperatives to save tokens.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is efficient and assumes Claude's competence (no explanations of what a browser or iframe is), but the "Iron Rules" section recapitulates six rules already stated in earlier sections, and the Core Mental Model loop is restated in the workflows. These minor repetitions could be trimmed. | 4 / 5 |
Actionability | Guidance is copy-paste ready throughout: concrete parameterized calls such as `BrowserAct { action: "click-css", selector: "button[type=submit]" }`, `BrowserWait { type: "urlIncludes", url: "/success" }`, `BrowserDownloadImage { selector: ".product-image" }`, and the `ToolSearch(names: …)` activation call, with common cases covered. | 5 / 5 |
Workflow Clarity | The three workflows are clearly sequenced with explicit validation checkpoints (snapshot after every action, `BrowserWait { type: "urlIncludes" }` to confirm login success, snapshot on every pagination page), the Error Diagnosis section provides feedback loops for recovery, and the Iron Rules act as a checklist. Pagination scraping includes per-page verification, so batch operations are not left unvalidated. | 5 / 5 |
Progressive Disclosure | The skill is a single self-contained file with no bundle references; all content (tool inventory, modes, workflows, error handling) is core operational guidance that appropriately lives in SKILL.md. Sections are well-organized with clear headers, making navigation easy, and nothing that belongs in a separate file is inlined. | 5 / 5 |
