## 作成 LocalTicketBackend によって作成されました。 --- ## State changed Ticket を `workspace-panel` が queued にしました。 --- ## Decision Routing decision: blocked_pending_dependency Panel Queue により routing 対象として確認したが、`00001KVHR3WSD` は `00001KVHR3WS6` に `depends_on` している。MCP `tools/call` execution は registered MCP tools を前提にするため、`00001KVHR3WS6` が closed になるまで実装開始せず queued のまま保持する。 Next: - `00001KVHR3WS6` が closed になった後、改めて reroute する。 --- ## Decision Routing decision: implementation_ready_parallel Reason: - User directive: 「blocker無いなら並列にやっちゃえよ」。この指示により、未解決 blocker がない Ticket は並列実装対象として扱う。 - 前回は `00001KVHR3WS6` tool registration が未完了だったため blocked/queued hold としたが、現在 `00001KVHR3WS6` は closed。 - Ticket body は MCP `tools/call` execution、permission-before-call、ordinary Tool result/history path、normal result / MCP `isError` / JSON-RPC protocol error の区別、bounded result serialization を実装可能な粒度で定義している。 - 現在 inprogress は Dashboard/Console TUI refactor `00001KVHX0WBE` のみで、作業領域は TUI/CLI naming/module boundary。MCP `tools/call` 実装とは直接 conflict しないため、別 worktree / sibling Coder Pod で並列化できる。 - Orchestrator worktree は clean、matching branch/worktree はなし。 - Risk domain は mcp / tools-call / permission / history / bounded-output だが、Ticket は permission denied before server request、ordinary Tool result/history path、bounded output、untrusted content treatment を明示している。bounded context check 後も implementation 前に必要な追加 human decision は見つからなかった。 Evidence checked: - Ticket `00001KVHR3WSD` body / thread / relations / artifacts。 - `TicketRelationQuery(00001KVHR3WSD)`: outgoing `depends_on 00001KVHR3WS6` is now closed。 - `TicketOrchestrationPlanQuery(00001KVHR3WSD)`: previous `blocked_by 00001KVHR3WS6` is resolved; accepted plan recorded now。 - Workspace state: - Orchestrator worktree clean at `381db88e`。 - inprogress: `00001KVHX0WBE` only。 - visible spawned child: Dashboard/Console Coder only。 - no matching MCP tools-call branch/worktree。 IntentPacket: Intent: - Route invocation of registered MCP-backed Yoi tools to MCP `tools/call` through ordinary Yoi Tool execution/result/history paths。 - Enforce existing PreToolCall / Tool permission policy before any MCP server request is sent。 Binding decisions / invariants: - Permission denial must occur before sending `tools/call` to the MCP server。 - MCP result content is untrusted and must not become hidden context injection。 - Results must be recorded through ordinary Tool call/result history path。 - Distinguish normal result, MCP `isError: true`, and JSON-RPC protocol error。 - Serialize content blocks / structuredContent / `_meta` boundedly; oversize/rich results must be truncated or rejected by explicit policy。 - Preserve lifecycle/registration redaction and bounds from previous MCP Tickets。 - Do not implement resources/read, prompts/get, list_changed, sampling, or elicitation in this Ticket。 Requirements / acceptance criteria: - MCP mock tool returns normal result through ordinary Yoi Tool result。 - MCP `isError: true` is represented distinctly from JSON-RPC protocol failure。 - Permission denied call is not sent to MCP server。 - Oversize/rich results are bounded/truncated or rejected according to explicit policy。 - Tool history shows ordinary tool call/result, not hidden context injection。 - Tests cover normal result, `isError`, protocol error, permission denial, and output bounds。 Escalate if: - Existing ToolRegistry contribution path cannot route invocation without broad provider-substrate redesign。 - Permission-before-call cannot be represented without changing Tool policy architecture。 - Result serialization requires product decisions beyond a safe bounded subset。 Next action: - Record `queued -> inprogress` and commit Ticket records before creating implementation worktree and spawning Coder。 --- ## State changed User explicitly authorized parallel implementation when no blocker exists. Ticket body/thread, relation metadata, closed MCP tool-registration dependency, Orchestrator worktree state, visible Pods, existing branch/worktree, and bounded MCP tools/call context were checked. Dependency `00001KVHR3WS6` is closed, no matching worktree/branch exists, and no missing planning decision was found. Accepting this queued Ticket for parallel implementation before worktree/Pod side effects. --- ## Implementation report Implementation orchestration start: - User explicitly authorized parallel work for Tickets without blockers。 - Acceptance records were committed on Orchestrator branch: `92432ad7 ticket: accept mcp tools call`。 - Created implementation worktree `/home/hare/Projects/yoi/.worktree/00001KVHR3WSD-mcp-tools-call` on branch `impl/00001KVHR3WSD-mcp-tools-call` at `92432ad7`。 - Spawned Coder Pod `yoi-coder-00001KVHR3WSD` with write scope limited to the implementation worktree and read-only root scope only for runtime workspace identity。 - Coder task explicitly forbids root/original workspace implementation, resources/prompts/list_changed scope creep, merge, Ticket close, and cleanup。 Next action: - Let MCP tools/call Coder proceed in parallel with Dashboard/Console Coder. Inspect implementation reports and route each to Reviewer when ready。 --- ## Implementation report Coder implementation report received from `yoi-coder-00001KVHR3WSD`. Implementation commit: - `9a245403 mcp: execute stdio tool calls` Changed areas reported: - `crates/mcp/src/stdio.rs`: - Added typed `CallToolRequest`, `CallToolResult`, and `McpContentBlock`。 - Added `McpStdioClient::call_tool(...)` for MCP `tools/call`。 - `crates/pod/src/feature/mcp.rs`: - Replaced discovery-only MCP tool stub with executable `McpStdioTool`。 - Execution spawns/initializes the configured stdio MCP server, sends `tools/call`, then shuts down。 - Result serialization is deterministic/model-visible/untrusted and bounded: content block cap, text/string truncation, JSON depth/node caps, binary/rich image/audio data omitted with size metadata, final output byte cap。 - MCP `isError: true` is represented as an MCP tool-level result distinct from JSON-RPC protocol errors。 - `crates/mcp/tests/fixtures/mock_server.rs`: - Added mock modes for normal `tools/call`, MCP `isError`, JSON-RPC protocol error, and no-call assertion。 - `crates/mcp/tests/stdio_lifecycle.rs`: - Added focused lifecycle/client tests for normal result, `isError`, protocol error, and permission-denial-style no-call。 Coder validation reported: - `cargo test -p mcp --test stdio_lifecycle`: passed, 12 tests。 - `cargo test -p pod feature::mcp`: passed, 9 tests。 - `cargo check -p mcp -p pod`: passed。 - `cargo fmt --check`: passed。 - `git diff --check`: passed。 - `nix build .#yoi --no-link`: passed。 Known deferrals: - MCP resources/read, prompts/get, list_changed, sampling, and elicitation remain unimplemented as requested。 - MCP `isError: true` is returned through ordinary `ToolOutput` with explicit `status: "mcp_is_error"` / `isError: true`; JSON-RPC failures remain `ToolError`s。 Orchestrator evidence checked before review dispatch: - Implementation worktree is clean。 - HEAD is `9a245403`。 - Diff from acceptance `92432ad7..HEAD` is one implementation commit touching 4 files, about 688 insertions / 11 deletions。 - `git diff --check 92432ad7..HEAD` produced no diagnostics。 Next action: - Dispatch Reviewer for r1 review against Ticket requirements, with focus on permission-before-call, ordinary Tool result/history path, `isError` vs protocol error distinction, output bounds/untrusted content, no resources/prompts/list_changed scope creep, and test coverage。 --- ## Plan Review dispatch: - Spawned Reviewer Pod `yoi-reviewer-00001KVHR3WSD-r1` against implementation branch `impl/00001KVHR3WSD-mcp-tools-call`。 - Review target commit: `9a245403 mcp: execute stdio tool calls`。 - Review baseline: `92432ad7`。 - Reviewer task focuses on permission-before-call, ordinary Tool result/history path, `isError` vs protocol error semantics, output bounds/untrusted content, lifecycle redaction/shutdown preservation, no resources/prompts/list_changed/sampling/elicitation scope creep, tests, and package validation。 - Reviewer is instructed not to edit source, commit, merge, close the Ticket, or use TicketReview directly; it will report verdict/evidence back to Orchestrator。 --- ## Review: approve Verdict: `approve` 確認範囲: - Ticket contract / Orchestrator IntentPacket。 - Implementation diff: `92432ad7..9a245403`。 - 主な対象: `crates/pod/src/feature/mcp.rs`, `crates/mcp/src/stdio.rs`, `crates/mcp/tests/stdio_lifecycle.rs`, `crates/mcp/tests/fixtures/mock_server.rs`。 - Ordinary Worker/permission path: `crates/llm-worker/src/worker.rs`, `crates/pod/src/permission.rs`, `crates/pod/src/feature.rs`。 - Out-of-scope MCP surfaces (`resources/read`, `prompts/get`, `list_changed`, sampling/elicitation) の追加有無。 Blocking issues: none。 Critical risk checks: - Permission denial occurs before `tools/call` can be sent: - MCP-discovered tools are ordinary `ToolDefinition`s wrapping `McpStdioTool`。 - Protocol-provider contributions install through `register_tool_contribution`, not a private bypass。 - Worker executes `pre_tool_call` first and only executes approved tools afterward。 - Pod manifest permissions are `PreToolCall` hooks returning deny as synthetic results。 - Result flow uses ordinary Tool result/history path: - `McpStdioTool::execute` returns `ToolOutput`。 - Worker converts to `ToolResult` and commits through existing history append path。 - No hidden context injection or out-of-band model context path found。 - Normal MCP result / MCP `isError: true` / JSON-RPC protocol error are distinct: - `CallToolResult` carries `is_error` separately from JSON-RPC error。 - MCP `isError: true` renders as model-visible untrusted data with `"status": "mcp_is_error"`。 - JSON-RPC error becomes `ToolError::ExecutionFailed` with protocol error wording。 - Output bounding/untrusted handling exists for content blocks, text/string caps, JSON depth/node caps, rich image/audio data omission, and final byte cap。 - Result root is marked `untrusted_mcp_tools_call_result` and preserves server payload as data。 - Existing lifecycle/redaction/shutdown behavior is preserved。 - No resources/prompts/list_changed/sampling/elicitation scope creep found。 Non-blocking concerns / follow-ups: - MCP-specific permission-denial test is lifecycle no-call style, while actual Worker deny/no-execute behavior is covered by generic Worker synthetic-result test path. Code inspection confirms MCP tools use ordinary Worker path, so this is not blocking. Future MCP-specific Worker-level regression would make the invariant more direct。 - Minor wording nit: successful `tools/call` with shutdown failure says “shutdown after tools/call failed”; functionally non-blocking。 Reviewer validation: - `git diff --check 92432ad7..HEAD`: passed。 - `cargo fmt --check`: passed。 - `cargo test -p mcp --test stdio_lifecycle`: passed, 12 tests。 - `cargo test -p pod feature::mcp`: passed, 9 tests。 - `cargo check -p mcp -p pod`: passed。 - `nix build .#yoi --no-link` not run by Reviewer because diff has no Cargo/Nix/source-filter changes and focused Rust checks passed。 Worktree status at review end: clean。 --- ## Implementation report Merge and final validation report: Merged implementation branch into Orchestrator branch: - Merge commit: `399a9d43 merge: mcp tools call` - Implementation commit included: - `9a245403 mcp: execute stdio tool calls` Reviewer outcome: - r1 approved with no blocking issues。 - Reviewer confirmed permission-before-call through ordinary Worker PreToolCall path, ordinary Tool result/history path, distinct MCP `isError` vs JSON-RPC protocol error, bounded/untrusted result serialization, and no resources/prompts/list_changed/sampling/elicitation scope creep。 Orchestrator validation after merge passed: - `cargo fmt --check` - `git diff --check HEAD^1..HEAD` - `cargo test -p mcp --test stdio_lifecycle` - `cargo test -p pod feature::mcp` - `cargo check -p mcp -p pod` - `nix build .#yoi --no-link` - `nix path-info -S .#yoi`: `113196368` Validation log: - `/run/user/1000/yoi/yoi-orchestrator/bash-output/bash-lkjYsX.log` Final state: - Orchestrator worktree clean at `399a9d43` after validation。 - Implementation worktree remains available for cleanup after Ticket completion records are committed。 - Dashboard/Console review remains active in parallel and is unaffected by this merge。 --- ## State changed Implementation was merged into Orchestrator branch at `399a9d43`, review approved, and final Orchestrator validation passed: `cargo fmt --check`, `git diff --check HEAD^1..HEAD`, `cargo test -p mcp --test stdio_lifecycle`, `cargo test -p pod feature::mcp`, `cargo check -p mcp -p pod`, and `nix build .#yoi --no-link`. --- ## State changed Ticket を closed にしました。 --- ## 完了 ## Resolution `00001KVHR3WSD` を完了しました。 実装内容: - MCP `tools/call` typed request/result/content types を追加しました。 - `McpStdioClient::call_tool(...)` を追加しました。 - MCP discovered tool の discovery-only stub を executable `McpStdioTool` に置き換えました。 - Execution は configured stdio MCP server を spawn/initialize し、`tools/call` を送信して shutdown します。 - Permission denial は ordinary Worker `PreToolCall` path により Tool execution 前に適用されるため、denied call は MCP server に送信されません。 - Results は ordinary Tool result/history path を通ります。Hidden context injection はありません。 - Normal MCP result、MCP `isError: true`、JSON-RPC protocol error を区別しました。 - MCP content / structuredContent / `_meta` / rich output は untrusted data として bounded に serialization されます。 - Image/audio data は raw payload を落とし、size metadata のみ残します。 - Resources/read、prompts/get、list_changed、sampling、elicitation は実装していません。 主な commit: - `9a245403 mcp: execute stdio tool calls` - `399a9d43 merge: mcp tools call` Review: - r1 は `approve`。 - Reviewer は permission-before-call、ordinary Tool result/history path、`isError` と protocol error の区別、bounded/untrusted result handling、out-of-scope surface が無いことを確認しました。 最終 validation: - `cargo fmt --check` - `git diff --check HEAD^1..HEAD` - `cargo test -p mcp --test stdio_lifecycle` - `cargo test -p pod feature::mcp` - `cargo check -p mcp -p pod` - `nix build .#yoi --no-link` Package impact: - `nix path-info -S .#yoi`: `113196368` Validation log: - `/run/user/1000/yoi/yoi-orchestrator/bash-output/bash-lkjYsX.log` ---
