chrome-devtools

Uses Chrome DevTools via MCP for efficient debugging, troubleshooting and browser automation. Use when debugging web pages, automating browser interactions, analyzing performance, or inspecting network requests. This skill does not apply to `--slim` mode (MCP configuration).

Quality

Content

75%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is well-structured, actionable, and respectably concise, with concrete tool names and clear sequenced workflows. The main gaps are the lack of an explicit validation feedback loop and full example tool-call invocations.

Suggestions

Add an explicit validate → fix → retry feedback loop for fragile automation (e.g., after take_snapshot, verify expected element uid is present before interacting; if not, re-snapshot and retry) to push workflow_clarity toward 5.

Show at least one complete example tool call with its arguments (e.g., a take_snapshot / click pair with parameters) rather than naming tools only in prose, to strengthen actionability.

Tighten the extension-testing blockquote (the JSON config block is useful but the surrounding prose can be condensed) and fix the "Addional" typo to improve conciseness.

DimensionReasoningScore

Conciseness

The body is mostly lean, assumes Claude's intelligence (no explanation of what DevTools is), and uses terse bullets with concrete tool names; the extension blockquote with the JSON config and some prose adds minor padding that could be trimmed.

4 / 5

Actionability

Provides concrete tool names (navigate_page, take_snapshot, click, fill, evaluate_script) and specific parameters (filePath, pageIdx, pageSize, includeSnapshot), plus a copy-paste JSON config; tool invocations are described in prose rather than shown as complete call examples with arguments, leaving minor gaps.

4 / 5

Workflow Clarity

Multi-step processes are clearly sequenced (Navigate → Wait → Snapshot → Interact; the 5-step extension test flow) with a "Before proceeding" checkpoint and an element-not-found retry hint, but there is no explicit validate → fix → retry feedback loop for fragile automation runs.

4 / 5

Progressive Disclosure

Well-organized into clear sections (Core Concepts, Workflow Patterns, Troubleshooting) with appropriate one-level-deep external doc links and no bundle files to reference; at ~70 lines it slightly exceeds the under-50-lines simple-skill threshold that would allow a 5 on structure alone.

Description

87%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is strong: it states concrete capabilities, gives explicit "Use when" triggers, and carves out a distinct niche with a clear boundary note. Minor gains are possible by de-duplicating the automation phrasing and adding a few more natural synonyms.

DimensionReasoningScore

Specificity

Lists several concrete actions ("debugging web pages, automating browser interactions, analyzing performance, or inspecting network requests") but "troubleshooting" is somewhat generic and "browser automation"/"automating browser interactions" overlap, leaving minor coverage gaps versus a fully comprehensive list.

4 / 5

Completeness

Explicitly answers both what ("Uses Chrome DevTools via MCP for efficient debugging, troubleshooting and browser automation") and when ("Use when debugging web pages, automating browser interactions, analyzing performance, or inspecting network requests") with concrete trigger phrases.

5 / 5

Trigger Term Quality

Includes natural user-facing phrases ("debugging web pages", "analyzing performance", "inspecting network requests", "browser automation") that users would actually say, though a few common synonyms (e.g. "inspect element", "console errors") are missing.

4 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (Chrome DevTools via MCP) and adds an explicit boundary ("This skill does not apply to `--slim` mode"), minimizing conflict with other skills.
