From e8b625e22f343d75e1b50d1634b4ab06899d060b Mon Sep 17 00:00:00 2001 From: tanaka takashi Date: Mon, 10 Aug 2026 19:38:55 +0900 Subject: feat(tools): add dir internal tool for directory operations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 新規Internal Tool `dir` を追加し、ディレクトリの作成・削除・一覧取得を 可能にした。file_editの拡張ではなく独立toolとして実装し、LLMが 「ディレクトリ操作はdir tool」と直感的に判断できるようにした。 追加した機能: - dir tool (6番目のInternal Tool、MCP非公開) - mkdir: Write capability要求、Directory.CreateDirectory()で親ディレクトリも含めて作成 - rmdir: Delete capability要求、空ディレクトリのみ削除(非空はToolValidationExceptionで拒否) - list: Read capability要求、直下エントリ一覧を返す 設計判断: - file_edit拡張ではなく新規toolとした理由: ツール名から機能が推測しやすく、 LLMが直感的に選択できるため - rmdirを空ディレクトリのみに制限した理由: rollback時の内容復元の複雑さを排除、 MemoryBackupLimit超過リスクなし、安全側 - mkdir/rmdirは既存のPathPolicy/ACL/Journal/Recovery枠組みを利用 - root継承ACE方式のため新規作成ディレクトリは自動的に親のACEを継承、追加ACL操作不要 変更対象: - InternalToolCatalog.cs: dir定義追加 (5→6 tool) - InternalToolDispatcher.cs: FakeInternalToolBackendの効果判定にdir追加 - InternalToolValidator.cs: dir用コメント追記 - WindowsToolBackend.cs: DirectoryOp()メソッド実装 - TransactionalFileEditor.cs: Mkdir()/Rmdir() transaction + DirectoryMkdirTransaction/DirectoryRmdirTransaction クラス追加 - RecoveryManager.cs: dir.mkdir/dir.rmdir crash recovery追加 - Specifications.md: FS-06追加 - Design.md: 6群表更新、§7.6 dir追加、5群→6群参照更新 テスト: - InternalToolTests.cs: dir単体テスト、catalog 6群検証、malformed args拒否 - SecurityPolicyTests.cs: mkdir/rmdir/list/許可外deny テスト追加 - PromptAndRuntimeTests.cs: tool count 5→6 - OllamaClientTests.cs: tool catalog配列長 5→6 検証結果: - Release build: 警告0、エラー0 - Planner tests: 10/10 PASS、skip 0 - Core tests: 56/56 PASS、skip 0 - MCP経由での動作確認: mkdir/list/rmdir/file_edit すべて正常 - Python実行確認: dir mkdir + file_edit + process_run でfib(1)〜fib(10)が正常出力 - Release Bundle publish済み 既知の運用上の知見: - uv venvのpyvenv.cfgのhomeがjunctionを指す場合、CanonicalPath.Resolveが reparse pointとして拒否する。実体パスへ書き換えるか、実体ディレクトリを agent.yamlのread/executeに追加する必要がある - venvのpython.exeはuv trampolineで子プロセスを生成するため、 sandboxのchild-process制限で拒否される。pyvenv.cfgが指す実体python.exeを 直接起動する必要がある --- doc/Design.md | 16 ++- doc/Specifications.md | 1 + src/Agent.Core/Tools/InternalToolCatalog.cs | 3 +- src/Agent.Core/Tools/InternalToolDispatcher.cs | 2 +- src/Agent.Core/Tools/InternalToolValidator.cs | 2 + src/Agent.Windows/Recovery/RecoveryManager.cs | 16 +++ .../Recovery/TransactionalFileEditor.cs | 51 ++++++++ src/Agent.Windows/Tools/WindowsToolBackend.cs | 34 ++++++ tests/Agent.Core.Tests/InternalToolTests.cs | 40 +++++- tests/Agent.Core.Tests/OllamaClientTests.cs | 2 +- tests/Agent.Core.Tests/PromptAndRuntimeTests.cs | 2 +- tests/Agent.Windows.Tests/SecurityPolicyTests.cs | 135 +++++++++++++++++++++ 12 files changed, 295 insertions(+), 9 deletions(-) diff --git a/doc/Design.md b/doc/Design.md index a908441..101a896 100644 --- a/doc/Design.md +++ b/doc/Design.md @@ -249,7 +249,7 @@ overrideはTask objectにcopyし、global configurationを変更しない。Sess - 既定上限は4画像、1画像10 MiB、request合計20 MiBとする。 - model capability確認でVision非対応と判定した場合はOllama呼出し前にlocalized error。能力確認不能時は呼出しを行い、Ollama errorを正規化して返す。 ### 6.5 Tool calling -Ollamaに公開するInternal Toolは次の5群に固定する。個々のOS command (`grep.exe`等) をtoolとして増殖させない。 +Ollamaに公開するInternal Toolは次の6群に固定する。個々のOS command (`grep.exe`等) をtoolとして増殖させない。 | Tool | 責務 | 主なoperation | | --- | --- | --- | | file_search | 検索 | glob / name / text / regex / tail相当 | @@ -257,6 +257,7 @@ Ollamaに公開するInternal Toolは次の5群に固定する。個々のOS com | file_edit | 編集 | overwrite / patch / atomic_replace / delete | | process_run | 承認済Process実行 | exe + args + cwd + timeout | | task_update | TaskGraph更新 | add / dependency / state / estimate | +| dir | ディレクトリ操作 | mkdir / rmdir / list | --- ## 7.
