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

kairan 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 21d 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 it actually says

kairan

agent が生成した markdown / HTML を tool call ひとつでブラウザに表示し、人間からのフィードバックを agent へ戻すローカル MCP サーバー。全体像・tool・設定は README.md を参照。

構成

ディレクトリ 役割
src/mcp/ stdio MCP ランチャー(agent が起動するプロセス)。tool 定義とデーモンへの操作窓口
src/daemon/ 表示サーバー(全 agent で 1 プロセス・1 port)。HTTP / SSE / SQLite / レンダリング / 通知
src/web/ ブラウザ側のクライアント。src/daemon/bundle.ts が実行時にバンドルする
src/shared/ ランチャー・デーモン・クライアントで共有する型と定数

品質チェック

コミット前に実行する。

bun run lint        # biome check .
bun run typecheck   # tsc --noEmit
bun test
bun run lint:fix    # 自動修正

コード変更の反映

  • デーモン側(src/daemon/ / src/web/): kairan restart
  • stdio ランチャー側(src/mcp/ / src/cli.ts): agent の MCP 再接続が必要(Claude Code は /mcp → Reconnect)

worktree のコードを試すときは、元 repo のデーモンを壊さないよう port とデータディレクトリを分ける。

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.
