Detect available browser interaction layer (Playwright MCP, Slicc playwright-cli, cmux-browser, CDP) and load the right commands — then navigate, click, fill, and screenshot through a unified verb set. Use before any browser interaction in skills that shouldn't hardcode a specific layer. Triggers on: browser universal, detect browser, browser layer, browser setup, which browser, browser interaction, open browser, use browser.

Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a strong description that clearly communicates a specific, well-defined capability: abstracting over multiple browser interaction layers to provide a unified interface. It excels at specifying concrete actions, naming the tools it abstracts over, providing explicit 'when to use' guidance, and listing comprehensive trigger terms. The description is concise yet thorough.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple concrete actions: 'detect available browser interaction layer', 'navigate, click, fill, and screenshot through a unified verb set', and names specific tools (Playwright MCP, Slicc playwright-cli, cmux-browser, CDP). Very specific about what it does. | 3 / 3 |
Completeness | Clearly answers both 'what' (detect browser layer, load commands, navigate/click/fill/screenshot via unified verbs) and 'when' ('Use before any browser interaction in skills that shouldn't hardcode a specific layer') with explicit trigger terms listed. | 3 / 3 |
Trigger Term Quality | Includes a comprehensive explicit trigger list covering natural variations: 'browser universal', 'detect browser', 'browser layer', 'browser setup', 'which browser', 'browser interaction', 'open browser', 'use browser'. These cover many ways a user or system might reference browser interaction needs. | 3 / 3 |
Distinctiveness Conflict Risk | Occupies a very clear niche — browser abstraction layer detection and unified browser interaction. The specific mention of tool names (Playwright MCP, Slicc, cmux-browser, CDP) and the 'unified verb set' concept make it highly distinct from any single-browser-tool skill. | 3 / 3 |

Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is an excellent skill that efficiently solves a real complexity problem — abstracting multiple browser interaction layers behind a unified interface. The detection logic is concrete and executable, the verb mapping table is immediately useful, and the progressive disclosure to LAYERS.md is well-structured. The security note and blocking error handling demonstrate good safety practices.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient. It doesn't explain what a browser is or how MCP works — it jumps straight into detection commands and verb mappings. Every section earns its place with no padding or unnecessary context. | 3 / 3 |
Actionability | Detection steps include concrete, executable shell commands with specific success criteria (exit codes, output patterns). The universal verbs table provides exact command names per layer. The error message when no layer is detected gives specific remediation steps. | 3 / 3 |
Workflow Clarity | The workflow is clearly sequenced: detect layers → apply priority → load reference → use universal verbs. Detection has explicit pass/fail criteria for each layer. The 'No Layer Detected' section is a clear blocking checkpoint. The universal pattern requiring re-snapshot after state changes is an explicit validation step. | 3 / 3 |
Progressive Disclosure | The skill provides a concise overview with the universal verb table inline (appropriate since it's the core quick-reference), while deferring detailed layer-specific commands, targeting models, and gotchas to a single one-level-deep reference (references/LAYERS.md). Well-signaled and appropriately split. | 3 / 3 |
