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 | $0.00015 | $0.06672 |
| Opus 5 | $0.00008 | $0.03336 |
| Sonnet 5 | $0.00003 | $0.01334 |
| Haiku 4.5 | $0.00002 | $0.00667 |
Grade A, and why
book 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 6d 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 — 1,005 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/book
Create a Book note with reading tracking and knowledge compounding through spawned Concept/Pattern/Theme nodes. Works for both quick capture and comprehensive PDF processing.
Usage
/book <title>
/book <title> by <author>
/book <title> --status reading
/book <title> --spawn # Identify concepts/patterns/themes to spawn
/book <title> --spawn "Data Contracts" # Spawn single specific node
/book <title> --spawn --concepts-only # Only spawn Concepts
/book <title> --spawn --patterns-only # Only spawn Patterns
/book <title> --spawn --themes-only # Only spawn Themes
/book <title> --spawn --preview # Preview content before creating
/book <title> --spawn --force # Re-analyse, ignore existing spawned nodes
/book <title> --spawn --enrich # Use web search to enrich definitions
/book <title> --pdf <path> # Process PDF with knowledge extraction
Modes

Instructions
Mode 1: Quick Capture (Haiku)
For simple reading tracking without knowledge extraction.

- Extract book title (required)
- Extract author if provided with "by"
- Extract optional flags:
--status,--rating,--format
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.

book is a skill published in the GitHub repository DavidROliverBA/ArchitectKB (52 stars, last pushed 6mo ago), licensed MIT. It adds 15 tokens to every session and 6,672 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 2026-08-30.
