Conciseness

Mostly lean, command-first sections with no explanations of concepts Claude already knows, but the global-install snippet ('npm install -g @playwright/cli@latest' / 'playwright-cli --help') appears in both the prerequisite section and Quick start, and the CODEX_HOME/PWCLI setup is duplicated in references/cli.md. Fits the 4 anchor's 'minor instances that could be trimmed' rather than the every-token-earns-its-place 5 anchor.

Actionability

Every section is copy-paste-ready bash: the prerequisite check ('command -v npx >/dev/null 2>&1'), the quick start ('"$PWCLI" open https://playwright.dev --headed' ... '"$PWCLI" screenshot'), and recipes for form fill, tracing, and multi-tab work. Matches the 5 anchor's fully executable guidance covering the common cases; not 4 because there are no gaps in the commands needed to run the workflow.

Workflow Clarity

The 5-step core workflow sequences open, snapshot, interact via refs, re-snapshot, capture artifacts; 'When to snapshot again' provides explicit checkpoints (navigation, modals, tab switches); and 'When a command fails due to a missing ref, snapshot again' is an explicit error-recovery feedback loop. Matches the 5 anchor (explicit validation steps plus recovery loops); not 4 because checkpoints and recovery are stated, not implicit.

Progressive Disclosure

The body is a concise overview whose References section clearly signals one-level-deep files ('CLI command reference: references/cli.md', 'Practical workflows and troubleshooting: references/workflows.md'), both of which exist in the bundle and hold the bulk command catalog and detailed workflows. Matches the 5 anchor's clear overview with well-signaled single-level references and an appropriate split; not 4 because navigation and placement have no notable gaps.

Specificity

The parenthetical lists six concrete actions — 'navigation, form filling, snapshots, screenshots, data extraction, UI-flow debugging' — plus the exact tool ('via playwright-cli or the bundled wrapper script'). Matches the 5 anchor's comprehensive multi-action list; not 4 because the action coverage has no significant gaps.

Completeness

Both halves are explicit: 'Use when the task requires automating a real browser from the terminal...' answers when, and the parenthetical action list plus the named tool answer what. Matches the 5 anchor (clearly answers both what AND when with concrete trigger phrases); not 4 because the 'when' clause is explicit and front-loaded rather than merely present.

Trigger Term Quality

Natural phrases users would say appear directly: 'automating a real browser', 'form filling', 'screenshots', 'data extraction', 'UI-flow debugging'. Common synonyms like 'web scraping', 'browser automation', or 'end-to-end' are absent, fitting the 4 anchor ('good keyword coverage; a few natural terms missing') rather than the comprehensive-synonym 5 anchor.

Distinctiveness Conflict Risk

'Automating a real browser from the terminal' plus the named playwright-cli tool carves a clear niche distinct from HTTP-fetch scraping or test-framework skills. However, 'screenshots' and 'data extraction' could also trigger dedicated screenshot or scraping skills, matching the 4 anchor's 'minor overlap risk with closely related skills' rather than the 5 anchor's minimal conflict risk.
