Quality

Content

38%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This skill reads as a general-purpose prompt engineering tutorial rather than an operational skill for Claude. It explains concepts Claude already understands deeply (few-shot learning, chain-of-thought, system prompts) and provides illustrative rather than executable examples. The content would benefit significantly from being trimmed to only novel, non-obvious guidance and restructured with clear workflows for specific prompt engineering tasks.

Suggestions

Remove explanations of concepts Claude already knows (what few-shot learning is, what chain-of-thought is, what system prompts are) and focus only on non-obvious patterns, gotchas, or project-specific conventions.

Add a concrete workflow with validation steps for prompt optimization: e.g., 1) Write initial prompt, 2) Test on N diverse inputs, 3) Score outputs against criteria, 4) Identify failure patterns, 5) Revise and re-test.

Split detailed examples and reference material (common pitfalls, best practices lists) into separate bundle files, keeping SKILL.md as a concise overview with navigation links.

Make the skill more actionable by specifying when and how Claude should apply these patterns in response to user requests, rather than describing the patterns abstractly.

DimensionReasoningScore

Conciseness

The skill extensively explains concepts Claude already knows well—prompt engineering fundamentals like few-shot learning, chain-of-thought, and system prompt design. Phrases like 'Improves accuracy on analytical tasks by 30-50%' and explanations of what few-shot learning is are unnecessary for Claude. Much of this is general knowledge padding rather than novel, actionable guidance.

2 / 5

Actionability

The examples provided are illustrative but not truly executable—they show prompt patterns rather than concrete steps to follow. The 'Prompt Optimization' section shows a conceptual progression rather than a reproducible process. The template system example is the most actionable piece, but overall the skill reads more like a tutorial than operational instructions.

3 / 5

Workflow Clarity

The 'Progressive Disclosure' pattern and 'Instruction Hierarchy' provide a rough sequence, but there are no validation checkpoints or feedback loops. The 'Prompt Optimization' section describes iteration conceptually ('measure performance, then iterate') without specifying how to validate or what constitutes success. For a skill that involves iterative refinement, the lack of explicit validation steps is a gap.

3 / 5

Progressive Disclosure

The content is a monolithic document with no references to supporting files, and at ~150+ lines it contains substantial content that could be split (e.g., detailed examples, best practices, common pitfalls into separate references). Everything is inlined with no navigation structure beyond section headers. No bundle files exist to offload detail.

Description

78%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.

This is a solid description that clearly communicates both what the skill does and when to use it, with a well-structured 'Use when' clause containing relevant trigger phrases. Its main weakness is that the 'what' portion uses somewhat abstract terms ('patterns, best practices, optimization techniques') rather than listing concrete actions the skill can perform. Adding more specific trigger terms and concrete capabilities would strengthen it further.

Suggestions

Replace abstract terms like 'patterns, best practices, optimization techniques' with concrete actions such as 'rewrite prompts for clarity, add few-shot examples, structure system prompts, apply chain-of-thought reasoning'.

Expand trigger terms to include common synonyms and related phrases like 'system prompt', 'few-shot', 'chain of thought', 'LLM prompt', 'prompt template'.

DimensionReasoningScore

Specificity

Names the domain (prompt engineering) and lists a few general areas ('patterns, best practices, optimization techniques'), but these are fairly abstract rather than concrete actions like 'rewrite prompts' or 'add chain-of-thought steps'. It sits between vague and specific.

3 / 5

Completeness

Clearly answers both 'what' (expert guide on prompt engineering patterns, best practices, optimization techniques) and 'when' (Use when user wants to improve prompts, learn prompting strategies, or debug agent behavior) with explicit trigger phrases.

5 / 5

Trigger Term Quality

Includes several natural keywords users would say: 'prompt engineering', 'improve prompts', 'prompting strategies', 'debug agent behavior'. Missing some common variations like 'system prompt', 'few-shot', 'chain of thought', 'prompt template', or 'LLM prompts'.

4 / 5

Distinctiveness Conflict Risk

Prompt engineering is a fairly distinct niche, and the trigger terms are specific enough to avoid most conflicts. Minor overlap risk with general coding/AI skills, but 'debug agent behavior' and 'prompting strategies' help differentiate it.
