A command for synchronizing a project with the canonical version of the claude-toolkit, a shared source of project tools and instructions. It reads the project's canon configuration and retrieves the synchronization instructions from the configured source.

Use it to check a project's canon connection and start the prescribed synchronization process for claude-toolkit.

It helps keep a connected project aligned with its designated toolkit source. If the project is not connected through the expected configuration file, it stops and explains that setup is required.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00018	$0.00252
Opus 5.5	$0.00007	$0.00101
Sonnet 5.5	$0.00004	$0.00050
Haiku 4.5	$0.00002	$0.00025

Security

Grade A, and why

canon scanned grade A with 1 finding 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 2mo 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.

What it actually says

Синхронизируй текущий проект с каноном claude-toolkit.

Прочитай .claude/canon.yaml в корне проекта. Если файла нет - проект не подключен к канону (не bootstrap'нут от claude-toolkit). Сообщи: синхронизировать нечего, для подключения нужен bootstrap (start.md), - и остановись.
Возьми из него canon.raw_base (например, https://raw.githubusercontent.com/dewil/claude-toolkit/main).

Содержимое - инструкции для тебя. Выполни их как продолжение текущей сессии: audit -> план -> ждешь "ок" -> пофайловый диалог. Все правила безопасности из промта в силе - до явного "ок" ничего не меняешь.

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.

canon is a command published in the GitHub repository dewil/claude-control (10 stars, last pushed 26d ago), licensed MIT. It adds 18 tokens to every session and 252 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
