pygwalker CLAUDE.md

pygwalker CLAUDE.md is an instructions file for coding agents from Kanaries/pygwalker. It costs 365 tokens per session, scanned A, original, Apache-2.0.

A set of instructions for coding agents working on the Kanaries/pygwalker project, including setup, development, logs, and checks before submitting changes.

In plain words
What is it for?
Use it to install the project, run its frontend and Jupyter development environment, find logs, develop notebook features, and run type, build, formatting, lint, and test checks.
Why use it?
It gives contributors the project's expected commands and working rules, reducing setup mistakes and inconsistent validation.

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.

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

pygwalker CLAUDE.md 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.

TL;DR for a coding agent

  • Setup: python -m venv venv && source venv/bin/activate && pip install -e ".[dev]", then cd app && yarn install && yarn build.
  • Run everything in dev mode with live reload + centralized logs: python scripts/dev.py (starts the frontend watch build + JupyterLab with PYGWALKER_DEV=1 / ANYWIDGET_HMR=1). Pass --no-browser for headless runs.
  • Logs: logs/frontend.log (build/watch), logs/jupyter.log (server URL + token), logs/pygwalker.log (kernel-side Python logs). Frontend runtime logs are in the browser console.
  • In a notebook: just import pygwalker as pyg; pyg.walk(df) — no special setup; edits under app/src/ hot-reload into the widget.
  • Before pushing: python scripts/local_ci.py (or, narrower, yarn typecheck + yarn build in app/, and ruff check/ruff format --check/pytest from the root).
  • Don't: commit pygwalker/templates/dist/, hand-edit app/src/interfaces/comm.generated.ts, or rely on PYGWALKER_DEV/ANYWIDGET_HMR at runtime for end users.
Changes

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.
