What it does

Gemini Commit Agent is an agent skill from Julian-adv/OpenMMO. Automated quality-assured commit workflow. Analyzes changes, runs linting/checking based on AGENTS.md, and prepares standardized commit messages.

Its SKILL.md is about 380 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/validate.sh`).

It sits in Development, covering Commit messages, Linting and formatting and Agent instruction files. It works with Google Gemini and npm.

When your agent uses it

  • Tasks that involve Commit messages
  • Tasks that involve Linting and formatting
  • Tasks that involve Agent instruction files

Example prompts

  • “/gemini-commit-agent”

Requirements

  • A Bash shell

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Analysis: Run git status and git diff to understand the scope of changes.
  2. Detection: Identify which sub-projects have changed
  3. Validation: Execute the required quality checks for each changed area
  4. Summary: Present a concise summary of the changes and the validation results to the user.
  5. Drafting: Generate a commit message following the project's style
  6. Confirmation: Present the draft message and the list of files to the user.
  7. Execution: After receiving explicit user approval, execute the commit.

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
    • npm
    • cargo

    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

Gemini Commit Agent loads about 383 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 185 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~383

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 185 words (~383 tokens).

“This skill automates the process of committing changes while ensuring that all repository-specific quality standards are met as defined in AGENTS.md.”
