playwriter

Control the user's currently open Chrome tab through the Playwriter CLI (no new browser launch). Use when you need to inspect live UI state, run scripted browser actions, capture console output, or reproduce frontend issues directly in the user's tab.

Quality

Content

86%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, executable, and appropriately concise for a single-purpose skill. The main improvement is adding an explicit validation/retry loop for cases where scripted actions mutate the page.

Suggestions

Add a small validation/retry step in the Core Workflow (e.g. re-check page.url() or expected state after a mutation) to form an explicit feedback loop.

Merge or trim the redundant opening line and the overlap between 'Core Workflow' and 'Useful Commands' to tighten token use.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence; minor redundancy such as the opening line restating the description and 'Useful Commands' overlapping 'Core Workflow' could be trimmed.

4 / 5

Actionability

Copy-paste-ready, executable commands are given throughout (version check, session new, url/title, accessibility snapshot, row enumeration, hover popups, page.evaluate), covering the common cases.

5 / 5

Workflow Clarity

A clear Quick Start and Core Workflow sequence with a connection/tab confirmation checkpoint; no explicit validate->fix->retry loop, but the skill defaults to read-only inspection and requires announcing destructive actions.

4 / 5

Progressive Disclosure

Under 50 lines, single-purpose, no bundle files needed, with well-organized sections and a single one-level-deep pointer to the external docs URL.

Description

82%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 clear, distinct, and answers both 'what' and 'when' with concrete trigger phrases. The only notable issue is second-person voice ('Use when you need to') which costs a specificity point.

Suggestions

Rewrite the trigger clause in third person to match best practice, e.g. 'Use when needing to inspect live UI state, run scripted browser actions, capture console output, or reproduce frontend issues directly in the user's tab.'

Consider adding a couple of common synonyms ('debug the UI', 'automate the active browser tab') to broaden natural trigger coverage.

DimensionReasoningScore

Specificity

Lists several concrete actions ('inspect live UI state, run scripted browser actions, capture console output, or reproduce frontend issues'), which is solid, but the 'Use when you need to' clause is second person, so specificity is reduced by 1 per the voice guideline.

3 / 5

Completeness

Explicitly states what it does ('Control the user's currently open Chrome tab through the Playwriter CLI') and when to use it with concrete trigger phrases, matching the top anchor.

5 / 5

Trigger Term Quality

Natural user-facing terms like 'Chrome tab', 'live UI state', 'console output', and 'reproduce frontend issues' are present; a few common synonyms (e.g. 'debug', 'automate browser') are missing.

4 / 5

Distinctiveness Conflict Risk

A clear niche tied to a specific CLI and the user's active tab with 'no new browser launch' makes conflict with other skills minimal.
