md2idx: Instructions file for Claude Code

CLAUDE.md

md2idx CLAUDE.md is an instructions file for Claude Code from oubakiou/md2idx. It costs 231 tokens per session, scanned A, a copy of mdxg-redline CLAUDE.md, MIT.

Project instructions for md2idx, a tool that turns Markdown documents into indexed JSON so large documents can be split and only relevant parts sent to a language model. They also specify checks for TypeScript changes.

In plain words
What is it for?
Use them when modifying, reviewing, or checking md2idx's TypeScript code, especially during file moves, import updates, or validation of editor and project diagnostics.
Why use it?
They explain the project's purpose and the required tools for finding definitions, references, and type errors. This helps an agent follow the repository's workflow when files or imports change.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: names the AskUserQuestion tool; mentions Claude Code; mentions AGENTS.md.

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

md2idx 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 1mo 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.

Origin

This is a copy

100% identical to mdxg-redline CLAUDE.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

@AGENTS.md @CLAUDE.local.md

  • ユーザーに確認する場合はAskUserQuestion toolを利用して選択肢を提示する
  • TypeScript のコード調査・変更検証には Claude Code の LSP deferred tool を活用する。初回利用時は ToolSearch query="select:LSP" で schema を読み込んでから呼び出す。シンボルの定義 / 参照解決(goToDefinition / findReferences 等)と、変更後の型エラー・未解決 import の単一ファイル確認(getDiagnostics)を組み合わせる。ただし getDiagnostics は指定ファイル中心で全走査ではないため、横断的な最終確認は vp check を併用する。ファイル移動に伴う import パスの自動書き換えは行われないので、書き換えは別途行い getDiagnostics / vp check で検証する
Changes

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.
