At a glance

Run the repository commit workflow when the user explicitly asks to commit changes or create a save-point commit.

  • Explicitly asks to commit changes
  • SKILL.md covers Overview, Workflow, Commit Message Rules and Failure Handling
  • Runs Shell scripts from its folder; calls git, cargo and npm
  • Create a save-point commit

What it does

Codex Commit Agent is an agent skill from Julian-adv/OpenMMO. Run the repository commit workflow when the user explicitly asks to commit changes or create a save-point commit. Upload changed binary assets to Hugging Face and update assets.lock before committing, run required quality checks, and commit with an imperative English message without duplicate approval.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `agents/openai.yaml` and `scripts/validate.sh`).

It sits in AI & LLM Engineering, covering Commit messages and Model hubs and datasets. It works with Hugging Face and Git.

When your agent uses it

  • Explicitly asks to commit changes
  • Create a save-point commit

Example prompts

  • “/codex-commit-agent”

Requirements

  • A Bash shell

What it can do on your machine

Read from SKILL.md and the folder at commit e240930. 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

    Ships 1 file in scripts/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • git
    • cargo
    • npm
    • bash

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git and npm, which can reach the network depending on how they are called.

    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

Codex Commit Agent loads about 1.3k tokens when it runs. Until then it costs about 81 tokens; SKILL.md has 678 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~81
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 678 words (~1,284 tokens).

“Publish changed binary assets, validate changed areas, and commit the intended files with the updated asset lock. Treat an explicit user request to commit as authorization for git commit; do not ask again solely to approve an assistant-drafted message. A…”
