35%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill provides a comprehensive conceptual overview of the GAN-style harness pattern but suffers from significant verbosity and incomplete actionability. It explains too many concepts Claude already understands (GANs, product management, what Playwright does) while leaving critical implementation details undefined (the actual prompt files, the harness script). The content would benefit greatly from being split into a concise overview with references to detailed companion files.
Suggestions
Cut the content by at least 50%: remove the GAN explanation, the 'When to Use/Not Use' sections, the model evolution history, and the results table — or move them to a separate REFERENCE.md file. Focus the main skill on the executable workflow.
Provide or clearly define the referenced files (PLANNER_PROMPT.md, EVALUATOR_PROMPT.md, scripts/gan-harness.sh) — either inline their essential content or create them as companion files with clear navigation links.
Add explicit validation checkpoints to the workflow: verify dev server is running (curl localhost:3000), verify spec.md was created successfully, verify feedback file exists before next generation cycle.
Move the evaluation rubric, configuration table, and anti-patterns into separate reference files, keeping only a 2-3 line summary of each in the main SKILL.md with clear links.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is extremely verbose at ~300+ lines. It explains concepts Claude already knows (what GANs are, what a Product Manager does, what Playwright does), includes lengthy architecture diagrams, extensive rubric definitions, model evolution history, and results tables that are informational rather than actionable. Much of this could be condensed to 1/3 the length or split into reference files. | 1 / 3 |
Actionability | The manual Claude Code usage section provides concrete, executable commands, and the shell script examples are specific. However, the /project:gan-build commands appear to reference non-existent slash commands without explaining how to set them up, and the shell script references (./scripts/gan-harness.sh) assume infrastructure that isn't provided. The PLANNER_PROMPT.md and EVALUATOR_PROMPT.md files are referenced but never defined. | 2 / 3 |
Workflow Clarity | The manual usage section shows a clear sequence (Plan → Generate → Evaluate → Iterate), and the anti-patterns section addresses failure modes. However, there are no explicit validation checkpoints between steps (e.g., how to verify the dev server is running before evaluation, how to confirm the spec is well-formed before generation). The feedback loop termination condition (pass threshold) is mentioned but the actual decision logic for stopping vs continuing is implicit. | 2 / 3 |
Progressive Disclosure | The skill references external files (PLANNER_PROMPT.md, EVALUATOR_PROMPT.md, scripts/gan-harness.sh) but doesn't clearly signal where they are or provide them. The content that could be in separate reference files (the full evaluation rubric, the evolution stages, the results table, the configuration reference) is all inline, making the main file a monolithic wall. The external references section at the bottom links to papers rather than companion skill files. | 2 / 3 |
