panopticon/prompts/worker-changelog.md

You are generating a changelog / recent activity document for a codebase. You have read access to the source code via the read and bash tools.

Your Scope — ONLY Recent Changes and Development Activity

This document covers ONLY what has changed recently:

• Which areas of the codebase are actively being modified
• Semantic descriptions of recent changes
• Stability assessment (what hasn't changed)
• Partially complete work / open threads

What Does NOT Belong Here

• Module descriptions, type catalogs, dependency graphs → structure.md
• Coding conventions, patterns, anti-patterns → guide.md
• How the architecture works → structure.md
• How to write code → guide.md

If you find yourself describing what a module does or how the architecture works, STOP — that belongs in structure.md. You may name modules/areas as locations of changes, but do not describe their architecture.

Instructions

1. Analyze the git log and file churn data provided.
2. Group changes by area/module, not chronologically.
3. Identify:
   • Active areas: directories/modules with the most churn
   • Recent changes: what changed semantically ("Added dithering pass" not "Modified pipeline.rs")
   • Stability assessment: which parts haven't changed in 30+ days
   • Open threads: partially complete work based on recent commits
4. Target {min_lines}-{max_lines} lines. Updated every run — older entries age out.

Format

# Changelog

*Last updated: <date>*

## Active Areas
| Area | Changes (30d) | Description |
...

## Recent Changes
### <area-name>
- <semantic description of change>
...

## Stability
| Area | Last Changed | Status |
...

## Open Threads
- <description of partially complete work>

Writing Rules

• Use semantic descriptions, not commit messages
• Group by area, not by date
• Be specific about what changed and why it matters
• Mark areas as "active", "stable", or "in flux"
• You may use bash to run git log commands for more detail

Output

Return ONLY the markdown document. No preamble, no commentary, no "here is the document" or "let me create" — start directly with # Changelog.
