## 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、`00001KVHR3WSN` は `00001KVHR3WRY` に `depends_on` している。MCP resources/prompts operations は initialized stdio lifecycle を前提にするため、`00001KVHR3WRY` が closed になるまで実装開始せず queued のまま保持する。 Next: - `00001KVHR3WRY` 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」。現在 inprogress は 0 件であり、依存 blocker も解消済みのため、この queued Ticket を開始する。 - 前回は `00001KVHR3WRY` stdio lifecycle が未完了だったため blocked/queued hold としたが、現在 `00001KVHR3WRY` は closed。 - Ticket body は resources/list, resources/read, prompts/list, prompts/get を explicit tool operations として exposeし、hidden context injection を禁止し、ordinary Tool result/history path・untrusted/bounded content handling・pagination/list bounds を明確にしている。 - Orchestrator worktree は clean、matching branch/worktree はなし。 - Risk domain は mcp / resources / prompts / prompt-context / history / untrusted-content だが、Ticket は explicit Tool operations、ordinary history、no hidden injection、bounded/rich content serialization 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 `00001KVHR3WSN` body / thread / relations / artifacts。 - `TicketRelationQuery(00001KVHR3WSN)`: outgoing `depends_on 00001KVHR3WRY` is now closed。 - `TicketOrchestrationPlanQuery(00001KVHR3WSN)`: previous `blocked_by 00001KVHR3WRY` is resolved; accepted plan recorded now。 - Workspace state: - Orchestrator worktree clean at `6ac916c7`。 - queued: `00001KVHR3WSN`, `00001KVHR3WSW`。 - inprogress: 0。 - spawned child implementation Pods: 0。 - no matching MCP resources/prompts branch/worktree。 IntentPacket: Intent: - Expose MCP resources/prompts as explicit namespaced Yoi tool operations: `resources/list`, `resources/read`, `prompts/list`, `prompts/get`。 - Returned resources/prompt templates are untrusted Tool result data and must be recorded through ordinary Tool result/history paths。 - Do not inject resource/prompt content directly into model context outside Tool history。 Binding decisions / invariants: - No hidden context injection path。 - All returned content/templates are untrusted data。 - Bound result sizes and rich/embedded content serialization。 - Handle pagination/list bounds where applicable。 - Diagnostics identify server/resource/prompt operation without leaking secrets。 - Do not implement MCP tool execution itself beyond existing completed support。 - Do not implement list_changed refresh, sampling, or elicitation in this Ticket。 - Preserve prior MCP lifecycle/tool-call redaction/bounds/ordinary Tool path behavior。 Requirements / acceptance criteria: - `resources/list` and `resources/read` can be invoked as explicit tools。 - `prompts/list` and `prompts/get` can be invoked as explicit tools。 - Results are ordinary Tool results and history records。 - No hidden context injection path is introduced。 - Oversize/rich content is bounded。 - Tests cover list/read/get happy paths, untrusted content, bounds, and no hidden injection。 Escalate if: - Existing ToolRegistry/provider path cannot represent resources/prompts operations without broad provider-substrate changes。 - MCP prompt message/content serialization requires product decision beyond safe bounded Tool result data。 - Hidden context injection would be needed to satisfy a feature expectation; that would violate Ticket intent and must stop。 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 lifecycle dependency, Orchestrator worktree state, visible Pods, existing branch/worktree, and bounded MCP resources/prompts context were checked. Dependency `00001KVHR3WRY` is closed, no inprogress/capacity blocker exists, no matching worktree/branch exists, and no missing planning decision was found. Accepting this queued Ticket for implementation before worktree/Pod side effects. --- ## Implementation report Implementation orchestration start: - Acceptance records were committed on Orchestrator branch: `b2b4764f ticket: accept mcp resources prompts tools`。 - Created implementation worktree `/home/hare/Projects/yoi/.worktree/00001KVHR3WSN-mcp-resources-prompts-tools` on branch `impl/00001KVHR3WSN-mcp-resources-prompts-tools` at `b2b4764f`。 - Spawned Coder Pod `yoi-coder-00001KVHR3WSN` 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, hidden context injection, list_changed/sampling/elicitation scope creep, merge, Ticket close, and cleanup。 Next action: - Wait for Coder implementation report, then inspect branch diff/validation evidence and route to Reviewer。 --- ## Implementation report Coder implementation report received from `yoi-coder-00001KVHR3WSN`. Implementation commit: - `3a22360a mcp: expose resources prompts tools` Changed areas reported: - `crates/mcp/src/stdio.rs`: - Added typed MCP protocol structs/helpers for `resources/list`, `resources/read`, `prompts/list`, and `prompts/get`。 - Added resource/prompt request/result models preserving untrusted server-owned fields as data。 - `crates/pod/src/feature/mcp.rs`: - Registers explicit namespaced MCP operation tools when server capabilities advertise resources/prompts: - `Mcp__resources_list` - `Mcp__resources_read` - `Mcp__prompts_list` - `Mcp__prompts_get` - Executes these through ordinary `Tool` path using `ToolOutput`。 - Serializes resource/prompt content as bounded untrusted JSON tool-result data。 - Bounds list items, resource contents, prompt messages, text fields, JSON depth/node count, rich embedded blobs/images/audio, and total output bytes。 - Preserves existing MCP `tools/call` behavior and redacted diagnostics。 - Does not add hidden context injection; prompt/resource data is not appended as user/system messages。 Tests reported: - Operation tool naming/origin/schema。 - Discovery registers resource/prompt operations without requiring `tools` capability。 - `resources/list` and `resources/read` happy paths through ordinary tool output。 - `prompts/list` and `prompts/get` happy paths through ordinary tool output。 - Untrusted prompt/resource content remains data。 - Rich/oversize resource/prompt content is bounded/omitted/truncated。 Coder validation reported: - `cargo test -p pod mcp::tests`: passed, 13 tests。 - `cargo check -p pod -p mcp`: passed。 - `cargo fmt --all --check`: passed。 - `git diff --check`: passed。 - `cargo test -p mcp`: passed, 12 stdio lifecycle tests。 - `nix build .#yoi --no-link`: passed; dirty-tree warning expected because validation ran before commit。 Known deferrals / notes: - `list_changed` refresh remains deferred。 - Sampling/elicitation not implemented。 - MCP resources/prompts tools are registered from advertised server capabilities; unsupported capabilities are not exposed as model-visible tools。 Orchestrator evidence checked before review dispatch: - Implementation worktree is clean。 - HEAD is `3a22360a`。 - Diff from acceptance `b2b4764f..HEAD` is one implementation commit touching 2 files, about 1225 insertions / 36 deletions。 - `git diff --check b2b4764f..HEAD` produced no diagnostics。 Next action: - Dispatch Reviewer for r1 review against Ticket requirements, with focus on explicit tool operations, ordinary Tool result/history path, no hidden context injection, untrusted/bounded content serialization, capability-gated registration, pagination/bounds, no list_changed/sampling/elicitation scope creep, and tests。 --- ## Plan Review dispatch: - Spawned Reviewer Pod `yoi-reviewer-00001KVHR3WSN-r1` against implementation branch `impl/00001KVHR3WSN-mcp-resources-prompts-tools`。 - Review target commit: `3a22360a mcp: expose resources prompts tools`。 - Review baseline: `b2b4764f`。 - Reviewer task focuses on explicit tool operations, ordinary Tool result/history path, no hidden context injection, untrusted/bounded resource/prompt content serialization, capability-gated registration, pagination/bounds, diagnostics redaction, no 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: `b2b4764f..3a22360a`。 - 変更 source files: - `crates/mcp/src/stdio.rs` - `crates/pod/src/feature/mcp.rs` - Focus: explicit tool exposure、capability-gated registration、ordinary `ToolOutput` execution、untrusted/bounded serialization、pagination behavior、diagnostics、hidden context injection / sampling / elicitation / `list_changed` scope creep absence。 Blocking issues: none。 Approval evidence: - `crates/mcp/src/stdio.rs` に resources/prompts protocol structs and request helpers が追加されている。 - `ListResourcesResult`, `ReadResourceRequest`, `ReadResourceResult` - `ListPromptsResult`, `GetPromptRequest`, `GetPromptResult` - `McpPromptMessage` and resource/prompt metadata fields。 - `McpStdioClient` exposes explicit request methods only: - `list_resources_page` -> `resources/list` - `read_resource` -> `resources/read` - `list_prompts_page` -> `prompts/list` - `get_prompt` -> `prompts/get` - Registration is capability-gated: - `resources` capability registers only `Mcp__resources_list` and `Mcp__resources_read`。 - `prompts` capability registers only `Mcp__prompts_list` and `Mcp__prompts_get`。 - Existing `tools/list` discovery is also gated by advertised `tools` capability。 - Resource/prompt operations are ordinary `Tool` implementations: - `McpStdioProviderOperationTool` implements `Tool::execute`。 - Results are returned as `ToolOutput { summary, content }`。 - No new `SystemItem`, hidden history append, hidden user/system message append, or direct context injection path found。 - Returned content is serialized as JSON-ish untrusted data with explicit marker fields: - `untrusted_mcp_resources_list_result` - `untrusted_mcp_resources_read_result` - `untrusted_mcp_prompts_list_result` - `untrusted_mcp_prompts_get_result` - Bounds are applied to list items, resource content count, prompt message count, text fields, `_meta`, extra/structured JSON depth/node count, rich image/audio blob omitted-data markers, and final rendered content bytes。 - Stdio reader remains fail-closed for unsupported server-to-client requests; no sampling, elicitation, or `list_changed` refresh was added。 - Tests cover operation namespacing, capability-gated registration without `tools`, resource list/read happy paths, prompt list/get happy paths, untrusted/bounded output, and existing MCP tool execution result serialization/bounds。 Non-blocking follow-ups: - “no context injection” は operation tool path / `ToolOutput` content unit testsで確認されており、E2E history inspection ではない。E2E 未設計の現状では許容だが、将来 MCP/history integration test があるとよい。 - Shutdown-warning text は result serialization 後に append される。`bounded_diagnostic` では bounded だが、厳密に post-append final content <= max result output bytes を要求するなら follow-up で final re-bound を追加してもよい。 Reviewer validation: - `git diff --check b2b4764f..HEAD`: passed。 - `cargo fmt --all --check`: passed。 - `cargo test -p pod mcp::tests`: passed, 13 tests。 - `cargo test -p mcp`: passed, 12 tests。 - `cargo check -p pod -p mcp`: passed。 - `nix build .#yoi --no-link`: passed。 Worktree status at review end: clean。 --- ## Implementation report Merge and final validation report: Merged implementation branch into Orchestrator branch: - Merge commit: `4a4590f8 merge: mcp resources prompts tools` - Implementation commit included: - `3a22360a mcp: expose resources prompts tools` Reviewer outcome: - r1 approved with no blocking issues。 - Reviewer confirmed explicit resources/prompts tool operations, capability-gated registration, ordinary `ToolOutput` execution, no hidden context injection path, untrusted/bounded serialization, no sampling/elicitation/list_changed scope creep, and focused tests。 Orchestrator validation after merge passed: - `cargo fmt --all --check` - `git diff --check HEAD^1..HEAD` - `cargo test -p pod mcp::tests` - `cargo test -p mcp` - `cargo check -p pod -p mcp` - `nix build .#yoi --no-link` - `nix path-info -S .#yoi`: `113403880` Validation log: - `/run/user/1000/yoi/yoi-orchestrator/bash-output/bash-4oVSE2.log` Final state: - Orchestrator worktree clean at `4a4590f8` after validation。 - Implementation worktree remains available for cleanup after Ticket completion records are committed。 --- ## State changed Implementation was merged into Orchestrator branch at `4a4590f8`, review approved, and final Orchestrator validation passed: `cargo fmt --all --check`, `git diff --check HEAD^1..HEAD`, `cargo test -p pod mcp::tests`, `cargo test -p mcp`, `cargo check -p pod -p mcp`, and `nix build .#yoi --no-link`. --- ## State changed Ticket を closed にしました。 --- ## 完了 ## Resolution `00001KVHR3WSN` を完了しました。 実装内容: - MCP `resources/list`, `resources/read`, `prompts/list`, `prompts/get` の typed protocol structs / helpers を追加しました。 - Server capabilities に応じて explicit namespaced Yoi tools を登録します。 - `Mcp__resources_list` - `Mcp__resources_read` - `Mcp__prompts_list` - `Mcp__prompts_get` - Resources/prompts operations は ordinary Tool path / `ToolOutput` を通って実行されます。 - Returned resources / prompt templates / prompt messages は untrusted Tool result data として serialization され、hidden context injection はありません。 - Result serialization は list items、resource contents、prompt messages、text fields、`_meta`、structured JSON depth/node count、rich blobs/images/audio、final output bytes を bounded に扱います。 - Capability が advertise されていない operation は model-visible tool として expose されません。 - `list_changed` refresh、sampling、elicitation は実装していません。 主な commit: - `3a22360a mcp: expose resources prompts tools` - `4a4590f8 merge: mcp resources prompts tools` Review: - r1 は `approve`。 - Reviewer は explicit Tool operations、ordinary `ToolOutput` path、no hidden context injection、untrusted/bounded serialization、capability-gated registration、no sampling/elicitation/list_changed scope creep を確認しました。 最終 validation: - `cargo fmt --all --check` - `git diff --check HEAD^1..HEAD` - `cargo test -p pod mcp::tests` - `cargo test -p mcp` - `cargo check -p pod -p mcp` - `nix build .#yoi --no-link` Package impact: - `nix path-info -S .#yoi`: `113403880` Validation log: - `/run/user/1000/yoi/yoi-orchestrator/bash-output/bash-4oVSE2.log` ---
