A3.9/5.0
Scored across 13 tools
Disambiguation4/5
The set has a clear two-tier structure (one-shot extraction/verification vs. persistent session tools), and descriptions carefully separate them. However, extract_semantic_dom_after overlaps conceptually with the session_open/session_act/session_extract flow, and extract_semantic_dom vs session_extract require reading descriptions carefully to pick correctly.
Naming Consistency4/5
Almost everything is consistent snake_case verb_noun, and the session_* prefix gives a clean, predictable grouping. Minor deviation: extract_semantic_dom_after uses a temporal suffix rather than a distinct verb, which slightly breaks the pattern.
Tool Count5/5
13 tools is well within the sweet spot and each one earns its place, covering extraction, diagnostics, verification, conventions, and full session lifecycle without filler.
Completeness5/5
The surface covers the full Playwright test-authoring workflow: page mapping, snapshot extraction, post-interaction observation, locator verification, auth/frame diagnostics, conventions, and end-to-end session management with open/act/extract/verify/close/list. No obvious dead ends.
