kindle

kindle is a command for coding agents from masterleopold/book-capture. It costs 13 tokens per session (214 once invoked), scanned A, original, MIT.

A command for capturing a book from the Amazon Kindle app on a Mac, extracting its page text with OCR, and producing structured Markdown. OCR means converting text visible in images into editable text.

In plain words
What is it for?
Use it to capture a Kindle book, navigate its pages, recognize the text, and create structured Markdown notes from the result.
Why use it?
It removes the need to copy pages manually and prepares the captured content for further organization. The Kindle app must be open to the book’s first page and have Accessibility permission.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Install

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.

agentmods
npx agentmods add commands/masterleopold/book-capture/kindle
Clone the repo
git clone --depth 1 https://github.com/masterleopold/book-capture

Or install book-capture, the plugin that ships this one along with the rest of its 1 skill, 8 commands, 2 agents.

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

kindle 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.

Mac Kindle Book Capture

Source is pre-selected: kindle (Mac Kindle app).

Follow the full pipeline in ${CLAUDE_PLUGIN_ROOT}/commands/capture.md with source = kindle. Skip the platform selection step.

Kindle-specific notes:

  • App name is Amazon Kindle (not Kindle)
  • Uses Page Down key for navigation (arrow keys don't work)
  • Script sends Escape to dismiss startup dialogs
  • Remind user: open the book in Amazon Kindle app to the first page, ensure Accessibility permission

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.
