counterpoise-ledger: Skill for Claude Code

.claude/skills/verify/SKILL.md

verify is a skill for Claude Code from jeffjjohnston/counterpoise-ledger. It costs 41 tokens per session (865 once invoked), scanned A, original, MIT.

A runtime-checking recipe for Counterpoise, a web application, that uses a local development server, seeded test data, and browser automation to verify interface changes.

In plain words
What is it for?
Starting the development app, logging in with test credentials, opening the transactions page, and interacting with transaction rows to check the changed behavior.
Why use it?
It helps confirm that a UI change works in the running app rather than only passing code-level tests, while avoiding confusion with deployed code.

This is jeffjjohnston/counterpoise-ledger's own configuration. It tells Claude Code how to work on counterpoise-ledger itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything counterpoise-ledger configures →

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

verify 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 7d 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 — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Maintainer setup — adapt paths for your fork. Container names are pinned by name: in docker-compose.yml, so those are the same in every checkout.

Verifying Counterpoise changes at runtime

Launch

When the production Docker container (counterpoise-rust-api-1) is running locally, it holds host port 3000 and serves deployed code — not your working tree. Always run the dev servers on other ports so the two can't be confused. Run two processes, both in the background:

# 0. Once, with no server running on the file: the sample data
npm run db:seed

# 1. The Rust API server, on its own port
RUST_BIND=127.0.0.1:4100 \
  cargo run --manifest-path rust-api/Cargo.toml -p counterpoise-rust-api   # ready when /health returns 200

# 2. The Vite dev server, which proxies /api to that Rust server
RUST_API_URL=http://127.0.0.1:4100 npm run dev -- --port 3001   # ready when /login returns 200

The Vite port is strict: if 3001 is in use, Vite stops with an error. Pick another port. The Rust server uses the SQLite file data/counterpoise.db in this checkout (set DATABASE_PATH for another file). It needs no Docker and no production environment file. Only one server can use a file: a second one stops with "another server uses ...". npm run db:seed also refuses while a server holds the file, so seed before you start the server. Rust code changes need a restart of the Rust server; client changes reload in the browser.

Login

Seeded dev credentials: username admin, password password (created by npm run db:seed). Log in at /login, then navigate to /b/1/transactions (seed book id is 1; the household seed names it "Family Finances"). The seed dates end today. Add -- --today YYYY-MM-DD to npm run db:seed to pin them, and -- --dataset single for the single-homeowner dataset. A full single seed names its book "Demo Book - Single".

Drive

  • Playwright MCP tools (mcp__plugin_playwright_playwright__browser_*) work well; load via ToolSearch first.
  • The transactions page redirects to a favorite account (?accountId=N) on load.
  • Find target rows via browser_evaluate over tbody tr; right-click with browser_click + button: "right"; the row actions menu is [role="menu"] with [role="menuitem"] children. The ⋯ overflow button is button[aria-label="Transaction actions"].
  • Toasts auto-dismiss quickly — query for them within ~1s of the action (a browser_evaluate that clicks and then polls in the same call works).

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.
