Codewhale is an open-source coding agent that runs in the terminal and can read repositories, edit files, execute commands, and inspect results while pursuing a task. Developers use it with hosted providers or local models, with controls for how much access it receives.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00308 |
| Opus 5.5 | $0.00000 | $0.00123 |
| Sonnet 5 | $0.00000 | $0.00062 |
| Haiku 4.5 | $0.00000 | $0.00031 |
Grade A, and why
github scanned grade A with 1 finding 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 4d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
Never proceed with `curl` against api.github.com as a silent fallback — What it actually says
name: github description: GitHub via gh — issues, PRs, reviews, search, and CI runs. Use when: user mentions a repo, issue, PR, review, release, workflow run, or anything on github.com. invocation: model+user
GitHub
When to use
Any GitHub work: read or triage issues, open or review PRs, search code, check CI runs, manage releases.
Setup
Requires the gh CLI, authenticated. Fail loud when it is missing:
gh auth status || gh auth login
Never proceed with curl against api.github.com as a silent fallback —
gh owns auth, pagination, and output shape.
Workflow
- Confirm the repo (
owner/name) and, for mutations, the exact target. - Read:
gh issue view,gh pr view,gh pr diff,gh search,gh run view. - Mutate only when asked:
gh issue create,gh pr create,gh pr review,gh pr merge. Mutations need explicit user intent, not inference. - Quote what
ghreturned; never summarize a diff or check rollup you did not read.
Non-goals
- Do not merge, close, or approve on your own initiative.
- Do not invent issue/PR numbers or check conclusions.
- Do not push, retag, or rewrite history without explicit authorization.
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 is a skill published in the GitHub repository Hmbown/Codewhale (41,027 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 308 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-19.

codew-release-qa-sweep
Use before claiming Codewhale release work is done: run the full gate sweep and list the manual QA targets.
gh-find-prs
Survey open Codewhale PRs and triage each for mergeability and disposition against the real landing branch.
gh-credit-harvest
Harvest one community PR into a release branch with authorship and credit preserved, verified green, and a warm thank-you.
release
Skill "release" from Hmbown/Codewhale, covering release, invocation, non-goals and workflow.
contributor-onboarding
Help a new contributor get productive on this checkout - inspect sync state against main, build, run the repository's exact verification gate, and produce a local what's-new digest. Never fetches, pulls, or modifies a dirty tree on its own. Explicit-only.
gh-close-issues
Close resolved Codewhale issues only after verifying the landed commit/behavior, with a positive crediting comment; never from title alone.
