commit

commit is a skill for Claude Code, Codex from martinemde/dotfiles. It costs 59 tokens per session (561 once invoked), scanned A, original, ISC.

A guide for finishing changes in jj, a version-control system similar to Git. It covers describing the current change, separating unrelated work, and leaving the working copy clean.

In plain words
What is it for?
Use it to inspect a diff and recent history, split unrelated files, write a short change description, and advance to a clean working copy.
Why use it?
It prevents mixed changes from being bundled together and avoids vague descriptions of what changed. It also explains that jj's working copy is already a commit.

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

commit 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 1mo ago.

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.

How it starts

The opening of the file, as written. The whole thing — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Commit

Produce a clean atomic history ending on a fully clean working copy. In jj the working copy is already a commit, so "committing" is really two questions: is this change described well, and should @ advance.

Look first

Run these together — the description depends on all three:

jj diff                                                      # what actually changed
jj log -r "ancestors(@, 10)" --template builtin_log_oneline   # this repo's style
jj status                                                    # @'s current description

Split before describing

If @ holds unrelated changes, separate them rather than writing a description that lists two things:

jj split -m "message" <files>                # peel off part of @
jj squash --use-destination-message <files>  # fold files into the parent

Write the description

It should complete the phrase "This commit will…", and explain why in the body — the diff already shows what. One or two sentences.

Match the style you saw in the log. Where that log uses conventional commits, follow it; where it doesn't, don't introduce it. The verb carries meaning worth keeping consistent: "add" for something wholly new, "update" for an enhancement to what exists, "fix" for a bug. Add Fixes #NN when an issue closes.

For multi-line messages, use a heredoc so quoting doesn't mangle the body:

jj commit -m "$(cat <<'EOF'
Description here.

Co-Authored-By: Claude <[email protected]>
EOF
)"

Pick the command from @'s state

@ right now Command
Already well described jj new — or jj new -m "next plan"
Needs a description, ready to move on jj commit -m "..." — describes and advances
Needs a description, more work coming jj desc -m "..."

Then run jj status in the same message to confirm where you landed. When this is a handoff into new work, jj new -m "<goal of the new work>" starts it named.

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.
