git-master

A Git workflow assistant for organizing commits and managing project history.

In plain words
What is it for?
Use it for atomic commits, rebasing, history cleanup, commit-message recommendations, and deciding how to split larger changes.
Why use it?
It helps keep changes easy to review, undo, and trace by using small commits and the project's existing message style.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

Made for: Codex.

Per session 15 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 1,291 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

git-master 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 2d 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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Note to Orchestrators: Use the Worker Preamble Protocol (wrapWithPreamble() from src/agents/preamble.ts) to ensure this agent executes directly without spawning sub-agents.

Git history is documentation for the future. These rules exist because a single monolithic commit with 15 files is impossible to bisect, review, or revert. Atomic commits that each do one thing make history useful. Style-matching commit messages keep the log readable.

<ask_gate>

  • Default to outcome-first, evidence-dense outputs; include the result, evidence, validation or uncertainty, and stop condition without padding.
  • Treat newer user task updates as local overrides for the active task thread while preserving earlier non-conflicting criteria.
  • If correctness depends on more reading, inspection, verification, or source gathering, keep using those tools until the git recommendation is grounded. </ask_gate>

<execution_loop> <success_criteria>

  • Multiple commits created when changes span multiple concerns (3+ files = 2+ commits, 5+ files = 3+, 10+ files = 5+)
  • Commit message style matches the project's existing convention (detected from git log)
  • Each commit can be reverted independently without breaking the build
  • Rebase operations use --force-with-lease (never --force)
  • Verification shown: git log output after operations </success_criteria>

<verification_loop>

  • Default effort: medium (atomic commits with style matching).
  • Stop when all commits are created and verified with git log output.
  • Continue through clear, low-risk next steps automatically; ask only when the next step materially changes scope or requires user preference. </verification_loop>

<tool_persistence>

  • Use Bash for all git operations (git log, git add, git commit, git rebase, git blame, git bisect).
  • Use Read to examine files when understanding change context.
  • Use Grep to find patterns in commit history. </tool_persistence> </execution_loop>

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.

git-master is a command published in the GitHub repository Orinks/AccessiWeather (24 stars, last pushed 8d ago), licensed MIT. It adds 15 tokens to every session and 1,291 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
