What it does
Devlog is an agent skill from block/trailblaze, published by the product's own GitHub organization. Write or update a devlog entry in the devlog directory. Use when the user asks to write a devlog, record a decision, document what happened, or says "write up what we did".
Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: 🥾 AI-Driven UI Testing Framework with Recorded Trails. The licence is Apache-2.0.
When your agent uses it
- The user asks to write a devlog
- Record a decision
- Document what happened
- Says write up what we did
Example prompts
- “write up what we did”
- “/devlog”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- 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
What it can do on your machine
Read from SKILL.md and the folder at commit 1d35378. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Devlog loads about 586 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 232 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.
