This skill should be used when the user says "visual readiness", "check visual layers", "activate visual layer", "visual checkpoint", "promote visual testing", "enable layer 2", "visual test health", "check deferred layers", "activate deferred layers", "layer promotion", or wants to validate and activate deferred visual testing layers after project milestones.

Discovery
22%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 description is almost entirely composed of trigger phrases with virtually no explanation of what the skill actually does. It fails to describe any concrete actions, outputs, or capabilities. While the trigger phrases provide some distinctiveness, they feel artificially constructed rather than reflecting natural user language, and the absence of a 'what does this do' component is a critical gap.
Suggestions
Add concrete capability descriptions explaining what the skill does, e.g., 'Validates visual testing layer configurations, checks readiness criteria, and promotes deferred layers to active status in the test pipeline.'
Replace or supplement the enumerated trigger phrases with a natural 'Use when...' clause that describes the user's intent, e.g., 'Use when the user wants to check the status of visual testing layers or activate deferred visual tests after a project milestone.'
Explain the domain context—what are 'visual testing layers' and 'deferred layers'? This helps Claude understand the skill's purpose and distinguish it from other testing or visual-related skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description lists trigger phrases but never describes concrete actions or capabilities. Terms like 'validate and activate deferred visual testing layers' are vague and don't explain what the skill actually does (e.g., what files it modifies, what checks it performs, what output it produces). | 1 / 3 |
Completeness | The 'when' is heavily covered with trigger phrases, but the 'what' is almost entirely missing. The description never explains what the skill actually does—what actions it performs, what outputs it produces, or what systems it interacts with. This is essentially all trigger and no substance. | 1 / 3 |
Trigger Term Quality | It includes many explicit trigger phrases like 'visual readiness', 'check visual layers', 'enable layer 2', etc. However, these feel like artificially constructed phrases rather than natural terms a user would organically say. They read more like command keywords than natural language. | 2 / 3 |
Distinctiveness Conflict Risk | The highly specific trigger phrases make accidental conflicts unlikely, but the domain itself ('visual testing layers', 'deferred layers') is poorly defined. Without understanding what the skill does, it's hard to assess whether it would conflict with other visual testing or layer management skills. | 2 / 3 |

Implementation
62%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a highly actionable and well-structured workflow skill with clear sequencing, validation checkpoints, and error handling. Its main weakness is extreme verbosity — the content could likely be cut by 40-50% without losing any actionable information, as it over-explains context, repeats guidance across sections, and includes prose that Claude could infer. The progressive disclosure is reasonable with external references but the main file itself carries too much inline detail.
Suggestions
Reduce the introductory paragraphs significantly — the first 4 paragraphs before Prerequisites explain context Claude can infer from the workflow itself. Condense to 2-3 sentences max.
Move the detailed journey upgrade sub-workflow (Step 3 journey check + Step 5 journey upgrade) into a separate reference file, since it's a conditional sub-procedure that adds significant length to the main flow.
Consolidate the Error Handling section with inline error notes in the workflow steps — currently error cases are described twice (once in the step, once in the error handling section).
Remove explanatory phrases like 'The core problem this solves' and 'because nothing re-evaluates whether the project has reached the point where those layers can be activated' — these explain motivation Claude doesn't need.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is extremely verbose at ~300+ lines. It over-explains concepts like what deferred layers are, repeats information across sections (e.g., error handling duplicates workflow guidance), and includes extensive prose that could be condensed into tables or terse instructions. Many paragraphs explain context Claude could infer from the workflow steps themselves. | 1 / 3 |
Actionability | The skill provides highly specific, concrete guidance: exact field names to parse from CLAUDE.md, specific commands to run (`which [tool]`, `[tool] --version`), exact output formats with templates, precise agent invocation parameters, and detailed update instructions for each artifact. The steps are executable rather than abstract. | 3 / 3 |
Workflow Clarity | The 8-step workflow is clearly sequenced with explicit validation checkpoints (Step 2 validates active layers, Step 3 checks criteria before proceeding, Step 4 validates with spikes before promotion). It includes feedback loops (ask user for ambiguous criteria, ask before promoting partially validated layers), error recovery paths, and explicit sequential execution constraints for agent invocations. | 3 / 3 |
Progressive Disclosure | The skill references external files like `readiness-checklist.md`, `spike-checklist.md`, `journey-schema.md`, and `ensure-config.md`, which is good progressive disclosure. However, the main SKILL.md itself is monolithic — the entire 8-step workflow with all detail is inline rather than splitting detailed sub-procedures (like the journey upgrade flow or gitignore classification) into separate reference files. No bundle files were provided to verify references exist. | 2 / 3 |
