Devlog
Write or update a devlog entry in the devlog directory.
Devlog Format
Devlog entries are development journal posts that capture decisions, discoveries, and plans as work happens. They're written for the team — concise, honest, and useful for future reference.
Filename: YYYY-MM-DD-<topic-slug>.md
Use today's date and a short kebab-case topic slug.
Entry Structure
---
title: "Short Descriptive Title"
type: devlog
date: YYYY-MM-DD
---
# Title
## Summary
1-3 sentences on what this entry covers.
## <Sections as needed>
Use whatever sections make sense for the content. Common ones:
- What Changed
- Key Decisions (and rationale)
- What We Learned
- Open Questions
- Future Work
Keep it direct. No filler. Write like you're explaining to a teammate who will read this in 3 months.
Front Matter Fields
| Field | Required | Values |
|---|
title | Yes | Short descriptive title |
type | Yes | decision (architectural/technical choice) or devlog (development note) |
date | Yes | YYYY-MM-DD format |
Use type: decision when recording a significant architectural or technical choice. Use type: devlog for development notes, debugging sessions, and implementation details.
Guidelines
- Be opinionated. Capture why decisions were made, not just what happened.
- Include the dead ends. What didn't work and why is often more valuable than what did.
- Link to context. Reference PRs, branches, test names, file paths — make it traceable.
- One entry per topic. Don't combine unrelated work. Multiple entries on the same day is fine.
Before Writing
- Check existing devlog entries to avoid duplicating a topic
- If updating an existing topic, consider appending to the existing entry rather than creating a new one
- Review the current conversation context for decisions, discoveries, and rationale worth capturing
Invocation
When the user says /devlog, ask what topic to write about if it's not clear from context. If you've been working on something substantial in the current session, suggest writing about that.
