Finishing a Development Branch
obra/superpowers
Walks the last step of a branch: confirm tests pass, detect the git environment, ask how to integrate, carry out your choice and clean up the worktree.
Scan all .md files in the project and add or fix YAML frontmatter (summary + readwhen) so they can be discovered by context routers like Reflex.

What it does
Add Frontmatter is an agent skill from markmdev/meridian. Scan all .md files in the project and add or fix YAML frontmatter (summary + readwhen) so they can be discovered by context routers like Reflex.
Its SKILL.md is about 440 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development. The repository describes itself as: Zero-config Claude Code setup with enforced task scaffolding, structured memory, persistent context after compaction, plug-in code standards, optional TDD mode, and zero behavior…
When your agent uses it
- Development work in your project
Example prompts
- “/add-frontmatter”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Glob all .md files, excluding skip dirs
- For each file: check if frontmatter with summary and read_when already exists
- If missing or incomplete: read the file content, infer a concise summary and 2-4 read_when keywords from the actual content
- Prepend the frontmatter block (or insert after existing --- if only partially present)
- Write the updated file
What it can do on your machine
Read from SKILL.md and the folder at commit d9b8775. 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.
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
Add Frontmatter loads about 444 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 201 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 201 words (~444 tokens).
“Scan every .md file in the project and ensure it has the required frontmatter so Reflex can discover and route it.”
