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 | $0.00282 |
| Opus 5.5 | $0.00000 | $0.00113 |
| Sonnet 5 | $0.00000 | $0.00056 |
| Haiku 4.5 | $0.00000 | $0.00028 |
Grade A, and why
money 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 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.
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.
What it actually says
name: money description: Bank accounts, balances, and transactions via Plaid. Use when: bank, balance, transactions, spending, accounts, or plaid. invocation: model+user
Money
When to use
Account balances, transaction history, and spending analysis across the user's bank accounts.
Setup
Requires Plaid API credentials. Fail loud when they are missing:
PLAID_CLIENT_ID=... PLAID_SECRET=... # sandbox keys first, production only when asked
The Link flow opens in the user's browser — the user completes it, the agent
drives everything after token exchange. Start in sandbox; touch
production only with explicit approval.
Workflow
- Exchange the public token once:
POST /item/public_token/exchange. - Balances:
POST /accounts/balance. History:POST /transactions/syncwith its cursor, paging untilhas_moreis false. - Report with dates, merchant names, and amounts; call out pending vs posted.
- Spending analysis aggregates by category or merchant on request.
Non-goals
- Do not move money, pay bills, or initiate transfers. Read-only, always.
- Do not store account or routing numbers beyond the session need.
- Do not paste secrets into chat, logs, or files.
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.

money 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 282 tokens. 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 2026-09-19.
Other skills, from other repositories
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.
best-of-n
Generate a small set of independent candidate solutions in worktrees, judge them against one explicit rubric, and apply the winner only after PASS verification.
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.
fleet-manager
Use when managing, triaging, restarting, escalating, or summarizing Codewhale fleet runs and workers.
handoff
Write a compact, decision-ready handoff so the next session (or the user) can continue without reconstructing the current one. Use when the session is ending, context is running low, the user asks for a handoff / 'pass the baton' / 'hand off', or a long-running operation needs a durable state checkpoint.
