notebook

A command that creates or refreshes and then runs the computational notebook paired with a textbook chapter. The notebook may use Python, R or Quarto, depending on the project setup.

In plain words
What is it for?
Reading the chapter plan, dispatching the notebook-writing agent, executing the notebook end to end, and reporting failures or mismatched numerical results.
Why use it?
It keeps notebook work separate from prose drafting while checking that the notebook executes successfully and meets the chapter's numerical targets.

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

notebook 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 2d 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

/bookwright:notebook

Dispatch the notebook-author agent to draft (or refresh) the paired notebook for a chapter. Separate command from /bookwright:draft so notebooks can be updated without re-drafting prose.

What it does

  1. Reads the chapter's plan file to find the notebook content checklist and numerical-sanity targets.
  2. Reads docs/superpowers/bookwright.config.yaml to determine notebook stack (Python+uv / R+renv / Quarto).
  3. Dispatches the notebook-author agent to draft or update the notebook.
  4. The agent executes the notebook end-to-end and reports execution exit code + observed numerical values.
  5. If execution fails or observed values miss the sanity targets, surfaces the discrepancy for the user to review.

Stack-specific execution commands

  • Python+uv+Jupyter: cd <project-dir>/notebooks && uv run jupyter nbconvert --to notebook --execute <name>.ipynb --output <name>.ipynb
  • R+renv+RMarkdown: cd <project-dir>/rmd && Rscript -e 'rmarkdown::render("<name>.Rmd")'
  • Quarto: cd <project-dir>/qmd && quarto render <name>.qmd

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.

notebook is a command published in the GitHub repository queelius/claude-anvil (2 stars, last pushed 1mo ago), licensed MIT. It adds 16 tokens to every session and 311 once invoked, about $0.0001 per session on Opus 5. 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 2026-08-31.
