Windows-native MCP agent sandbox for Ollama with LPAC, NTFS ACL, Job Objects, and WFP. https://git.takashi-2521.com/winagent-sandbox-mcp.git/atom?h=main 2026-08-13T13:48:24+00:00 2026-08-13T13:48:24+00:00 tanaka takashi isazaka@gmail.com 2026-08-13T13:48:24+00:00 urn:sha1:9337ac3e5edd42bb17f5e2ade6c2de02c7ef576d Run agent-mcp with an explicit asInvoker manifest and move WFP and loopback mutations into a fixed requireAdministrator helper under the release admin directory. Add the Agent.Admin client and host projects with task-scoped runas launch, a logon-SID and Administrators-only local named pipe, remote-client rejection, mutual PID validation, strict versioned JSON framing, fixed network-only operations, and bounded messages. Delay ACL and network Task Resource application until the first process_run. Verify executable identity, managed entry points, DNS snapshots, and normal-token WRITE_DAC access before elevation; reuse the helper only within the Task and keep elevation failures terminal without policy replanning. Keep LPAC creation, executable approval, Job confinement, and ACL leases in the normal process. Make startup platform checks read-only, create the fixed Application Profile during apply, preserve dynamic WFP lifetime in the helper, and route persistent loopback recovery through the same elevated boundary. Update recovery journaling, localized elevation and IPC errors, audit events, release publishing, manifests, README guidance, Specifications, Design, implementation records, and requirement traceability for the on-demand elevation model. Add administrative-boundary, file-only no-elevation, elevation-terminal, lazy-resource, crash-recovery, manifest, IPC schema, and operational verification coverage. Verified Release build with zero warnings, Core 105/105, Planner 10/10, administrative boundary 4/4, elevated Windows suite 79/79, and published stdio/HTTP MCP E2E. 2026-08-11T20:44:54+00:00 tanaka takashi isazaka@gmail.com 2026-08-11T20:44:54+00:00 urn:sha1:b56614c814b904c224315a11f9686f0d47abd3d3 Rewrite the specification and design vocabulary around User Sandbox Configuration, Environment Resolution, Executable Approval, Effective Sandbox Policy, and Windows Enforcement. Move the Internal Tool catalog to the design without treating its count as a requirement, and update README, implementation planning, traceability, audit history, prompts, and the Python skill. Introduce schema_version 1 profiles, workspaces, mounts, executable aliases, network modes, and resource presets. Add local override merging, resolution and approval stores with atomic user-only persistence, fail-closed fingerprints, localized diagnostics, and executable/sandbox management CLI commands. Change Windows execution to LPAC entry approval with inherited descendant confinement. Separate read and execute ACLs, preserve protected OS DACLs, apply Job process/memory/timeout limits to the tree, enforce WFP network modes, prevent credential environment inheritance, disable out-of-tree MSBuild reuse, and harden transactional ACL/recovery cleanup. Isolate planning prompts from execution instructions, reject split coding plans that cannot satisfy task-scoped evidence, preserve configured thinking, and prevent optional task_update failures from corrupting completion checks. Add and update configuration, resolution, approval, LPAC, descendant, readonly/development, Registry/COM, WFP, recovery, .NET/Python/PowerShell process-tree, and Operational E2E coverage. Publish reproducible bundles while preserving deployment-local configuration, prompts, skills, logs, state, approvals, and resolutions. 2026-08-11T15:21:23+00:00 tanaka takashi isazaka@gmail.com 2026-08-11T15:21:23+00:00 urn:sha1:98b6a2aeedd591058c1d81e401d24f3ded162926 Model Ollama chat thinking separately from final content, preserve it only across assistant tool-call continuation, and keep private reasoning out of user results, session context, and logs. Accept native boolean and low/medium/high/max think values, normalize YAML booleans, and serialize explicit overrides using the native top-level chat field. Stop forcing think=false for structured planning, skill selection, and context summaries; corrected retries now retain the configured thinking mode. Update the specification, design, audit report, and requirement traceability for OLL-14. Add request/response, configuration, observability, retry, and tool-continuation coverage. Verified with 92 passing Agent.Core tests and a deepseek-v4-flash:cloud think:true MCP operational run. 2026-08-11T15:02:23+00:00 tanaka takashi isazaka@gmail.com 2026-08-11T15:02:23+00:00 urn:sha1:ce550a127b7dc972651bd15b9f09979a2c38688f Replace the uv-specific skill with a portable Python skill and rewrite the default user system prompt as a concise, structured Markdown execution policy. Normalize a single fenced structured-JSON response, retry invalid skill selection with think disabled, validate selected skill output, and make coding plans keep editing and verification in one task. Document the file_edit patch payload, expose that contract in the tool catalog, and convert malformed patch input into a retryable tool failure instead of terminating the agent task. Update configuration and runtime tests for the Python skill, exact tool catalog, structured-output retry, and implementation-and-verification planning guidance. Verified with 82 Agent.Core tests and an agent-mcp Python scheduling scenario with 49 passing unittest cases. 2026-08-11T13:40:46+00:00 tanaka takashi isazaka@gmail.com 2026-08-11T13:40:46+00:00 urn:sha1:37386b89b6272f4cef34ab3bf131f11ed3afa13f 2026-08-11T13:36:21+00:00 tanaka takashi isazaka@gmail.com 2026-08-11T13:36:21+00:00 urn:sha1:8f8e82e00e5d0e9347feef10111faac788ad7d88 2026-08-11T13:23:27+00:00 tanaka takashi isazaka@gmail.com 2026-08-11T13:23:27+00:00 urn:sha1:ab69aaa72903b0ac5a35c4823ee97a629b3984fb 2026-08-11T13:20:25+00:00 tanaka takashi isazaka@gmail.com 2026-08-11T13:20:25+00:00 urn:sha1:842e55654db060c84448f3a0deddb24f77fad5a7 2026-08-11T13:10:55+00:00 tanaka takashi isazaka@gmail.com 2026-08-11T13:10:55+00:00 urn:sha1:d8cf8947ff93230ae5282fc5058b0e49ddae42aa 2026-08-11T13:07:37+00:00 tanaka takashi isazaka@gmail.com 2026-08-11T13:07:37+00:00 urn:sha1:24d8db0064d92e7ac783d2a3d23d49f314037600
