git-github

A set of Git and GitHub rules for this project. Git records code changes, while GitHub hosts the repository and supports collaboration through commits and pull requests.

In plain words
What is it for?
Use it when writing commits, checking staged changes before committing, protecting private identity details, handling the RHDH Local submodule, or deciding when force-pushing is allowed.
Why use it?
It helps keep the project history understandable and prevents personal email addresses, secrets, credentials, and unsafe force-pushes from entering the repository. It also documents how a related repository component should be handled.

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.

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-github 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 yesterday.

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 — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Git & GitHub Conventions

Commit Messages

Write clear, detailed commit messages that explain why the change was made, not just what changed.

Format

<short summary in imperative mood, max ~72 chars>

<optional body: explain motivation, context, trade-offs, or anything
non-obvious about the change. Wrap lines at ~72 chars.>

Guidelines

  • Use imperative mood: "Add feature" not "Added feature" or "Adds feature"
  • First line is a concise summary; add a blank line then a body for anything non-trivial
  • Reference related docs or issues when relevant (e.g. "See docs/architecture.md")
  • Group related changes into a single commit; separate unrelated changes into distinct commits

Email & Identity

This repository uses a GitHub noreply email to keep the author's personal email private.

  • NEVER change user.email in git config
  • NEVER use a personal email address in commits
  • The repo-level config is already set; do not override it

Secret Safety

Before every commit:

  1. Run git diff --staged and review for secrets, credentials, personal paths, or tokens
  2. NEVER commit files matching: .env, *-credentials.yaml, *.pem, *.key
  3. NEVER commit hardcoded passwords, API keys, tokens, or personal absolute paths (e.g. /Users/..., /home/...)
  4. Use ${ENV_VAR} references for all secrets; set real values only in the gitignored .env
  5. If in doubt, check .gitignore covers the file before staging

Submodule: rhdh-local

  • rhdh-local/ is a git submodule tracking the upstream RHDH Local project
  • modified: rhdh-local (untracked content) in git status is normal -- do not try to fix it
  • NEVER stage or commit changes inside rhdh-local/
  • To update the submodule: cd rhdh-local && git checkout main && git pull origin main && cd .. then commit the new SHA in rhdh-lab

Force Push

  • NEVER force push to main unless the user explicitly requests it
  • When rewriting history (e.g. email changes, squashing), always use --force-with-lease first; only fall back to --force if lease fails due to the rewrite itself

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.
