Use when writing or improving README files. Not all READMEs are the same — provides templates and guidance matched to your audience and project type.
Analyze recent code changes via git history and extract software engineering lessons. Use when the user asks 'what is the lesson here?', 'what can I learn from this?', 'engineering takeaway', 'what did I just learn?', 'reflect on this code', or wants to extract principles from recent work.
Use when writing prose humans will read—documentation, commit messages, error messages, explanations, reports, or UI text. Applies Strunk's timeless rules for clearer, stronger, more professional writing.
Comprehensive guide for creating software diagrams using Mermaid syntax. Use when users need to create, visualize, or document software through diagrams including class diagrams (domain modeling, object-oriented design), sequence diagrams (application flows, API interactions, code execution), flowcharts (processes, algorithms, user journeys), entity relationship diagrams (database schemas), C4 architecture diagrams (system context, containers, components), state diagrams, git graphs, pie charts, gantt charts, or any other diagram type. Triggers include requests to "diagram", "visualize", "model", "map out", "show the flow", or when explaining system architecture, database design, code structure, or user/application flows.
Manual-only skill for minimizing total codebase size. Only activate when explicitly requested by user. Measures success by final code amount, not effort. Bias toward deletion.
Create high-quality git commits: review/stage intended changes, split into logical commits, and write clear commit messages (including Conventional Commits). Use when the user asks to commit, craft a commit message, stage changes, or split work into multiple commits.
Creates detailed, sectionized implementation plans through research, stakeholder interviews, and multi-LLM review. Use when planning features that need thorough pre-implementation analysis.

READMEs answer questions your audience will have. Different audiences need different information - a contributor to an OSS project needs different context than future-you opening a config folder.
Always ask: Who will read this, and what do they need to know?
Ask: "What README task are you working on?"
| Task | When |
|---|---|
| Creating | New project, no README yet |
| Adding | Need to document something new |
| Updating | Capabilities changed, content is stale |
| Reviewing | Checking if README is still accurate |
Creating initial README:
Adding a section:
Updating existing content:
Reviewing/refreshing:
After drafting, ask: "Anything else to highlight or include that I might have missed?"
| Type | Audience | Key Sections | Template |
|---|---|---|---|
| Open Source | Contributors, users worldwide | Install, Usage, Contributing, License | templates/oss.md |
| Personal | Future you, portfolio viewers | What it does, Tech stack, Learnings | templates/personal.md |
| Internal | Teammates, new hires | Setup, Architecture, Runbooks | templates/internal.md |
| Config | Future you (confused) | What's here, Why, How to extend, Gotchas | templates/xdg-config.md |
Ask the user if unclear. Don't assume OSS defaults for everything.
Every README needs at minimum:
section-checklist.md - Which sections to include by project typestyle-guide.md - Common README mistakes and prose guidanceusing-references.md - Guide to deeper reference materials
