Quality

Content

82%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 a dense, highly actionable reference that assumes Claude's competence and provides concrete code, commands, and validation checkpoints throughout. Structure is strong, though some detailed fixture/debugging material could be split into reference files and the distributed workflows could be unified.

DimensionReasoningScore

Conciseness

Dense, table- and code-driven content that assumes VS Code competence with no concept padding; the debugging and fixture sections are detailed but justified, with only minor trims possible.

4 / 5

Actionability

Provides concrete file paths, interface names, runnable bash and @playwright/cli eval commands, TypeScript fixture snippets, and test commands that cover the common cases copy-paste ready.

5 / 5

Workflow Clarity

Clear sequences with explicit validation (verify core+sessions compile, blocksCi CI gates, wait-for-scrollbar-transition), but workflows are distributed across sections rather than one cohesive validate→fix→retry loop.

4 / 5

Progressive Disclosure

Well-organized with headers/tables and clearly signaled one-level references (the spec file, component-fixtures/sessions/launch skills); no bundle files exist, and some content like fixture tables and debugging snippets is inlined rather than split out.

Description

73%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 specific and well-scoped to a distinct component, with an explicit trigger clause and clear enumeration of managed item types. It is slightly held back by a generic action verb and a single, technical trigger phrase rather than multiple natural trigger variations.

Suggestions

Replace the generic verb "working on" with concrete actions (e.g., "editing, debugging, or extending") to lift specificity.

Add a second natural trigger phrase (e.g., "Use when the user asks to manage or customize agents, MCP servers, or prompts") to broaden trigger coverage.

Include common synonyms or file/section references users might mention (e.g., "customizations pane", "Chat settings") for fuller trigger-term coverage.

DimensionReasoningScore

Specificity

Names the domain ("Chat Customizations editor") and enumerates managed item types (agents, skills, instructions, hooks, prompts, MCP servers, plugins), but the verb "working on" is generic with no concrete actions listed.

3 / 5

Completeness

Has both an explicit "Use when..." trigger and a clear "what" (the management UI), but the "when" is a single, fairly technical trigger rather than multiple concrete trigger phrases.

4 / 5

Trigger Term Quality

Good coverage of natural terms users would say ("agents", "skills", "MCP servers", "prompts", "hooks"), but lacks synonyms and file extensions for full coverage.

4 / 5

Distinctiveness Conflict Risk

Scoped to a named, specific editor ("Chat Customizations editor") with distinct enumerated triggers, giving it a clear niche and minimal overlap risk with other skills.
