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 | $0.02089 | $0.02089 |
| Opus 5 | $0.01045 | $0.01045 |
| Sonnet 5 | $0.00418 | $0.00418 |
| Haiku 4.5 | $0.00209 | $0.00209 |
Grade A, and why
mcp-ts-morph 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 9d 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.

概要
MCP ts-morph Refactoring Tools - ts-morphを利用したTypeScript/JavaScriptのリファクタリングツールを提供するMCPサーバー。
開発コマンド
ビルド
pnpm build # TypeScriptをコンパイル(dist/に出力)
pnpm clean # distディレクトリをクリーン
テスト
pnpm test # テスト実行(単一スレッドで実行)
pnpm test:watch # ウォッチモードでテスト実行
pnpm test -- path/to/test.ts # 特定のテストファイルを実行
pnpm test:e2e # 実リポジトリ E2E(hono/zustand を clone して全ツール適用)
E2E テスト(pnpm test:e2e)
e2e/ は、バージョン固定の実 OSS(hono / zustand)を clone し、各 MCP ツールを
実プロジェクトに適用して「差分緑」(baseline と比較し新規型エラー・新規失敗テスト
が無いこと)を検証する。ユニットテストでは拾えない実世界の AST 不整合を掘り当てる
(例: move_symbol_to_file の逆向き import バグ)。
- デフォルトの
pnpm testからは除外(vitest.config.tsの exclude)。CI には 未組み込み(nightly + 手動 dispatch を予定)。 - 初回は clone + 依存インストールが走る(
bun/pnpmが必要。無ければ baseline 未取得で各ケース skip)。2 回目以降はe2e/.cache/*.readyマーカで再利用。 - 実行時間の目安: キャッシュ有りで 2〜3 分。
Claude への指示: src/ts-morph/** のリファクタロジック(特に
move-symbol-to-file / rename-* / remove-path-alias / change-signature)に
触れた変更は、仕上げ段階(コミット前 / PR 化前)で pnpm test:e2e を実行して
実リポジトリで退行が無いことを確認すること。時間がかかるので開発の各イテレーション
ではなく、まとまった作業の最後に回す。ネットワークや bun 不在で skip された場合は
その旨をユーザーに伝える。
型チェック・リント・フォーマット
pnpm check-types # TypeScriptの型チェック(コンパイルなし)
pnpm lint # Biomeでリントチェック
pnpm lint:fix # Biomeでリント修正
pnpm format # Biomeでコードフォーマット
デバッグ
pnpm inspector # MCP Inspectorでデバッグ実行
リリース(バージョン bump)
Git タグが単一の真実の source。手で bump しない。
package.jsonのversionとsrc/version.tsのVERSIONはどちらも0.0.0-developmentに固定。- リリースは
git tag vX.Y.Z && git push origin vX.Y.Zのみ。 .github/workflows/release.ymlが tag から値を抽出して両ファイルを書き換え、pnpm build→pnpm test→distの整合性確認 →pnpm publishを実行する。- 詳細手順は
.claude/skills/release/SKILL.mdおよび README の「リリース」セクション参照。 - ユーザーから「リリース」「タグを打って」等を言われたら release skill を使うこと。

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.
- 9d ago First seen · 163 lines · 2,089 tokens per session scan A 1577d6729e98
mcp-ts-morph CLAUDE.md is an instructions file published in the GitHub repository SiroSuzume/mcp-ts-morph (16 stars, last pushed 2mo ago), licensed MIT. It adds 2,089 tokens to every session, about $0.0104 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.
