A guide for managing GitHub repositories, which are online projects that store code and its history. It covers creating, cloning, forking, configuring, and working with repositories.

In plain words
What is it for?
Use it to create or copy repositories, configure remotes, inspect repository details, and perform routine GitHub administration.
Why use it?
It provides commands for common repository tasks and includes alternatives when the GitHub command-line tool is unavailable. It also explains how to identify the repository owner and name.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is gh release create v1.0.0 ./dist/binary --title "v1.0.0" --notes "Release notes".

Good fit Use it to create or copy repositories, configure remotes, inspect repository details, and perform routine GitHub administration.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

github-repo-management 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 8d 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 — 545 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GitHub Repository Management

Create, clone, fork, configure, and manage GitHub repositories. Each section shows gh first, then the git + curl fallback.

Prerequisites

  • Authenticated with GitHub (see github-auth skill)

Setup

if command -v gh &>/dev/null && gh auth status &>/dev/null; then
 AUTH="gh"
else
 AUTH="git"
 if [ -z "$GITHUB_TOKEN" ]; then
 if _hermes_env="${HERMES_HOME:-$HOME/.hermes}/.env"; [ -f "$_hermes_env" ] && grep -q "^GITHUB_TOKEN=" "$_hermes_env"; then
 GITHUB_TOKEN=$(grep "^GITHUB_TOKEN=" "$_hermes_env" | head -1 | cut -d= -f2 | tr -d '\n\r')
# Plaintext ~/.git-credentials is intentionally not used; prefer `gh auth login` or GITHUB_TOKEN in .env
 fi
 fi
fi

# Get your GitHub username (needed for several operations)
if [ "$AUTH" = "gh" ]; then
 GH_USER=$(gh api user --jq '.login')
else
 GH_USER=$(curl -s -H "Authorization: token $GITHUB_TOKEN" https://api.github.com/user | python3 -c "import sys,json; print(json.load(sys.stdin)['login'])")
fi

If you're inside a repo already:

REMOTE_URL=$(git remote get-url origin)
OWNER_REPO=$(echo "$REMOTE_URL" | sed -E 's|.*github\.com[:/]||; s|\.git$||')
OWNER=$(echo "$OWNER_REPO" | cut -d/ -f1)
REPO=$(echo "$OWNER_REPO" | cut -d/ -f2)

1. Cloning Repositories

Cloning is pure git — works identically either way:

# Clone via HTTPS (works with credential helper or token-embedded URL)
git clone https://github.com/owner/repo-name.git

# Clone into a specific directory
git clone https://github.com/owner/repo-name.git ./my-local-dir

# Shallow clone (faster for large repos)
git clone --depth 1 https://github.com/owner/repo-name.git

# Clone a specific branch
git clone --branch develop https://github.com/owner/repo-name.git

# Clone via SSH (if SSH is configured)
git clone [email protected]:owner/repo-name.git

With gh (shorthand):

gh repo clone owner/repo-name
gh repo clone owner/repo-name -- --depth 1

2. Creating Repositories

With gh:

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.
