85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-organized, highly actionable body with clear sequenced workflows and explicit verification steps. The main weakness is mild redundancy around the extension flag and an inline config block that slightly inflate the token budget.
Suggestions
De-duplicate the `--categoryExtensions` guidance: state the flag once in Core Concepts and have the Testing-an-extension section reference it rather than repeat the MCP JSON config.
Move the full `mcpServers` JSON config and the extension-testing details into a references file (e.g. references/extensions.md) and link to it from the body to keep SKILL.md a lean overview.
Tighten the Troubleshooting section by collapsing the two DevTools doc links and the troubleshooting.md link into a single one-line pointer.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient and tool-name-driven, but the extension-testing block repeats the `--categoryExtensions` flag already given in Core Concepts and embeds a full `mcpServers` JSON config that pads the overview. It could be tightened to earn the score-3 'every token earns its place' bar. | 2 / 3 |
Actionability | Provides executable, copy-paste-ready guidance: named tools, concrete parameters (`filePath`, `pageIdx`, `pageSize`, `includeSnapshot: false`), CLI flags, and a complete `mcpServers` JSON config, plus a numbered procedure mapping each step to a specific tool. | 3 / 3 |
Workflow Clarity | Sequences are explicit (navigate → wait → snapshot → interact) and the extension procedure includes explicit verification checkpoints (verify service worker, verify page behavior) plus a retry loop when an element is not found. | 3 / 3 |
Progressive Disclosure | No bundle files exist and none are referenced; the skill is a self-contained, cleanly sectioned overview (Core Concepts, Workflow Patterns, Troubleshooting), which is appropriate for its scope and avoids nested references. | 3 / 3 |
