From b07b41cd435991cd254957af79055080c85b346e Mon Sep 17 00:00:00 2001 From: tanaka takashi Date: Sun, 9 Aug 2026 21:08:20 +0900 Subject: feat: AI Agent Sandbox MCP Server v1を実装 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Specifications、Design、ImplementationPlanの優先順位を整理し、単一Task実行モデル、typed option優先、設定可能なresource上限、local Ollamaを必須とするRelease Gateを文書化。 .NET 10/C# 14の5 production project、3 test project、E2E Clientを構築。typed YAML、en/ja locale、fixed/user prompt、stdioおよびloopback限定Streamable HTTP、agent_run/agent_status、Session、Ollama text/tool/Vision、TaskGraphとtoken accountingを実装。 Windows sandboxとしてfixed AppContainer、canonical/reparse検査、能力別ACL、path+SHA-256 executable approval、child-process restriction、Job Object、task journal、atomic file transaction、crash recoveryを実装。WFPのIPv4/IPv6 default denyとexact allow、dynamic session、temporary loopback exemption、管理者/BFE診断を追加。 Security/Recovery test、MCP/Ollama integration test、stdio/HTTP Operational E2E、Release Bundle生成・checksum・manifest・fresh extraction検査を追加。Requirement TraceabilityとPhase 0〜11の進捗、初回セットアップ可能なREADMEを整備。 Debug/Release/publish/objをrepository rootのbuild/へ集約し、旧project-local bin/objへの依存を除去。artifacts/とbuild/をGit管理外に設定し、clean checkoutでもsolution buildからE2E Clientまで生成可能にした。 --- src/Agent.Core/Tools/InternalToolDispatcher.cs | 29 ++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 src/Agent.Core/Tools/InternalToolDispatcher.cs (limited to 'src/Agent.Core/Tools/InternalToolDispatcher.cs') diff --git a/src/Agent.Core/Tools/InternalToolDispatcher.cs b/src/Agent.Core/Tools/InternalToolDispatcher.cs new file mode 100644 index 0000000..7302c1f --- /dev/null +++ b/src/Agent.Core/Tools/InternalToolDispatcher.cs @@ -0,0 +1,29 @@ +using System.Text.Json; + +namespace Agent.Core.Tools; + +public sealed class InternalToolDispatcher(IToolPolicyEngine policy, IInternalToolBackend backend) +{ + public Task BeginTaskAsync(Guid taskId, CancellationToken cancellationToken) => backend.BeginTaskAsync(taskId, cancellationToken); + public Task EndTaskAsync(Guid taskId, bool success, CancellationToken cancellationToken) => backend.EndTaskAsync(taskId, success, cancellationToken); + + public async Task DispatchAsync(Guid taskId, string toolName, JsonElement arguments, CancellationToken cancellationToken) + { + InternalToolValidator.Validate(toolName, arguments); + ToolPolicyDecision decision = policy.Evaluate(toolName, arguments); + if (!decision.Allowed) return new(false, decision.Reason, false, $"policy:{toolName}:{decision.Reason}"); + return await backend.ExecuteAsync(taskId, toolName, arguments, cancellationToken).ConfigureAwait(false); + } +} + +public sealed class FakeInternalToolBackend : IInternalToolBackend +{ + private readonly List<(string Name, JsonElement Arguments)> _calls = []; + public IReadOnlyList<(string Name, JsonElement Arguments)> Calls => _calls; + public Task ExecuteAsync(Guid taskId, string toolName, JsonElement arguments, CancellationToken cancellationToken) + { + _calls.Add((toolName, arguments.Clone())); + bool effect = toolName is "file_edit" or "process_run"; + return Task.FromResult(new ToolExecutionResult(true, "fake-ok", effect)); + } +} -- cgit v1.2.3
