branch

branch is a skill for Claude Code, Codex from ahonn/dotfiles. It costs 64 tokens per session (375 once invoked), scanned A, original, MIT.

A rule for naming and creating Git branches with a type and short kebab-case description, such as feat/user-auth or fix/login-crash.

In plain words
What is it for?
Use it when starting work, branching from the default branch, validating a branch name, and creating the new branch.
Why use it?
It keeps branch names consistent and makes the purpose of each line of work clear before development begins.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

branch scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Conventional Branch Names

Branch names use the same type vocabulary as conventional commits:

<type>/<short-kebab-description>

Examples: feat/user-auth, fix/login-crash, refactor/api-client, chore/update-deps.

Rules

  1. Type — the conventional-commit type the dominant commit on this branch would have: feat, fix, refactor, perf, docs, test, build, ci, chore, revert.
  2. Description — 2–4 words, kebab-case, specific: what the branch delivers, not how. Lowercase only, no spaces.
  3. Ticket IDs — if the work has a ticket, put its ID after the type: feat/lin-123-user-auth.
  4. No agent-branded prefixes — never codex/..., claude/..., or agent/.... The branch describes the work, not the tool that wrote it.
  5. Base — branch off the up-to-date default branch unless the work explicitly builds on the current branch.

Procedure

  1. Derive type and description from the requested work (or "$ARGUMENTS" if provided).
  2. Validate: git check-ref-format --branch <name>.
  3. Create: git switch -c <name>.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
