claude-code-mastery CLAUDE.md

claude-code-mastery CLAUDE.md is an instructions file for coding agents from ShipWithAI/claude-code-mastery. It costs 3,996 tokens per session, scanned A, original, MIT.

Project instructions for a bilingual course that teaches developers how to use Claude Code, a command-line coding agent. The course is organized into phases, modules, and topics in English and Vietnamese.

In plain words
What is it for?
Use them when writing or revising course lessons, keeping the English and Vietnamese versions aligned, updating the table of contents, or preparing material for websites, books, notebooks, or workshops.
Why use it?
They help an agent keep the course structure, both languages, and its teaching approach consistent while the material is edited or expanded.

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

claude-code-mastery 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.

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.
