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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00017 | $0.04078 |
| Opus 5.5 | $0.00007 | $0.01631 |
| Sonnet 5.5 | $0.00003 | $0.00816 |
| Haiku 4.5 | $0.00002 | $0.00408 |
Grade A, and why
github-repo-management scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
88% identical to github-repo-management — 20 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 517 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GitHub Repository Management
Create, clone, fork, configure, and manage GitHub repositories. Each section shows gh first, then the git + curl fallback.
Prerequisites
- Authenticated with GitHub (see
github-authskill)
Setup
if command -v gh &>/dev/null && gh auth status &>/dev/null; then
AUTH="gh"
else
AUTH="git"
if [ -z "$GITHUB_TOKEN" ]; then
if _nyxora_env="${NYXORA_HOME:-$HOME/.nyxora}/.env"; [ -f "$_nyxora_env" ] && grep -q "^GITHUB_TOKEN=" "$_nyxora_env"; then
GITHUB_TOKEN=$(grep "^GITHUB_TOKEN=" "$_nyxora_env" | head -1 | cut -d= -f2 | tr -d '\n\r')
elif grep -q "github.com" ~/.git-credentials 2>/dev/null; then
GITHUB_TOKEN=$(grep "github.com" ~/.git-credentials 2>/dev/null | head -1 | sed 's|https://[^:]*:\([^@]*\)@.*|\1|')
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
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

github-repo-management is a skill published in the GitHub repository perasyudha/Nyxora (5 stars, last pushed 1mo ago), licensed MIT. It adds 17 tokens to every session and 4,078 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 88% identical to github-repo-management, differing in 20 lines, and is treated as a copy.
Other skills, from other repositories
git-wrapup
Land working-tree changes as logical commits — the work grouped by concern, topped by a release commit (version bump, changelog, regenerated artifacts). The work commits land first, then the version bump, verification, and the release commit on top. Stops at "committed locally on main" — or, when the project releases…
release-and-publish
Ship a release end-to-end across every registry the project targets (npm, MCP Registry, GitHub Releases for .mcpb bundles, GHCR). Runs the final verification gate, fast-forwards main when the release rode a release PR, creates the annotated tag on the commit main now points at, pushes commits and tags, then publishes…
git-workflow
Git workflow patterns including branching strategies, commit conventions, merge vs rebase, conflict resolution, and collaborative development best practices for teams of all sizes.
writing-modpack-changelog
Use when cutting a modpack release. Creates /docs/release-changelog.md if absent; appends a new version section with grouped changes. Triggers - 'cut a release', 'release notes', 'changelog', 'v1.2.3 changes', 'what changed since last version'.
changelog-gen
A changelog generator that turns Git history into a version-by-version record of project changes. A changelog is a readable summary of new features, fixes, breaking changes, documentation, and other updates.
antigravity-maintainer-batch-release
Run protected AAS maintainer sweeps, PR merge batches, canonical sync, Core preview checks, and scripted releases. Use for repository maintenance, main alignment, CLI/MCP/Workbench changes, or release work; not ordinary contribution tasks.
