A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

With the script output, perform this analysis:
#### A. Catalog the Explicit Suggestions
Create a table of mechanical fixes:
| Pattern | Original | Fixed |
|---|---|---|
| Grammar | "Its easier" | "It's easier" |
| Filler removal | "using this way" | "this way" |
| Capitalization | "Image Generation" | "image generation" |
#### B. Map Feedback to Changes
For each reviewer feedback comment:
Example:
Feedback: "would be nice to end more enthusiastically"
>
First draft: "...it's simple to add new tools to Claude and use them straight away."
>
Final: "...Let us know what you find and create in the comments below!"
>
Lesson: End blog posts with a call-to-action
#### C. Paragraph-by-Paragraph Comparison
Compare FIRST DRAFT to FINAL VERSION section by section:
#### D. Synthesize Style Patterns
Group findings into categories:
| Category | Patterns Found |
|---|---|
| Clarity | Passive→active, shorter sentences, remove filler |
| Precision | Vague→specific, "Create"→"Generate" |
| Tone | Added enthusiasm, call-to-action endings |
| Structure | Added transitions, better section flow |
| Grammar | its/it's, subject-verb agreement |
| Content | Added links, examples, context |

--diff | Adds FIRST/FINAL file dumps to the default output | Deep analysis of how the author responded |
--max-file-chars N | Truncates each FIRST/FINAL block to _N_ chars (appends ...[truncated X chars]) | Keep prompts within LLM token limits |
--no-files | Suppresses FIRST/FINAL dumps even when --diff is set | When you only need explicit suggestions + reviewer feedback |

## Style Lessons from PR #123
### Mechanical Fixes
- Fix grammar: "Its" → "It's" (contraction)
- Lowercase generic terms: "Image Generation" → "image generation"
- Remove filler: "the output quality of" → "the quality of"
### Reviewer-Driven Changes
- **"end more enthusiastically"** → Added call-to-action in conclusion
- **"emphasize these are SoTA"** → Changed "latest" to "state-of-the-art"
- **"add blurb about MCP Server"** → Added explanatory paragraph
### Structural Improvements
- Added transition sentence between sections
- Simplified setup instructions (3 sentences → 1)
- Added new bullet point for model flexibility--max-file-chars or pass --no-files to keep outputs prompt-friendly{{currentDate}} {{env}}
