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

1. Check existing devlog entries to avoid duplicating a topic
2. If updating an existing topic, consider appending to the existing entry rather than creating a new one
3. 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.
