## 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、`00001KVHR3WS6` は `00001KVHR3WRY` に `depends_on` している。MCP tools/list registration 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 Reason: - Panel Queue により、この Ticket は Orchestrator routing 対象として明示許可された。 - 前回は `00001KVHR3WRY` stdio JSON-RPC 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 `tools/list` による registration scope、metadata/schema normalization、ToolRegistry integration、no `tools/call` execution、no resources/prompts を明確に分離している。 - 現在 inprogress は 0 件、child implementation Pods はなし、matching branch/worktree はなし、Orchestrator worktree は clean。 - Risk domain は mcp / tools-list / ToolRegistry / schema / untrusted metadata だが、Ticket は server metadata を untrusted data として扱い、invalid schema / duplicate / collision を fail-closed、normal ToolRegistry pathを使い、no private MCP bypass / no `tools/call` during registration などの invariants 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 `00001KVHR3WS6` body / thread / relations / artifacts。 - `TicketRelationQuery(00001KVHR3WS6)`: outgoing `depends_on 00001KVHR3WRY` is now closed。Incoming `00001KVHR3WSD` / `00001KVHR3WSW` are downstream and not blockers。 - `TicketOrchestrationPlanQuery(00001KVHR3WS6)`: previous `blocked_by 00001KVHR3WRY` is resolved; accepted plan recorded now。 - Workspace state: - Orchestrator worktree clean at `68a8fc97`。 - queued: `00001KVHR3WS6`, `00001KVHR3WSD`, `00001KVHR3WSN`, `00001KVHR3WSW`。 - inprogress: 0。 - visible Pods: self + peers only; spawned children 0。 - no matching MCP tool-registration branch/worktree。 IntentPacket: Intent: - Use the stdio MCP lifecycle client to call `tools/list` and register discovered MCP tools as ordinary Yoi model-visible tools through existing `pod::feature` / ToolRegistry contribution paths。 - This Ticket implements registration/discovery only. It must not send `tools/call`, execute MCP tools, or expose resources/prompts。 Binding decisions / invariants: - Server-provided tool names, descriptions, schemas, annotations, and metadata are untrusted data。 - Normalize MCP tool names into stable namespaced Yoi tool names that include server namespace and avoid collisions。 - Validate/normalize descriptions and JSON schemas before ToolRegistry registration; invalid schemas/duplicates/collisions fail closed with bounded diagnostics。 - No server metadata may weaken Yoi instructions, scope, permissions, tool permissions, or system/developer instructions。 - Registration must go through normal ToolRegistry / `pod::feature` dynamic contribution path; no private MCP bypass。 - Do not send `tools/call` during registration。 - Do not register resources/prompts in this Ticket。 - Preserve lifecycle safety/redaction from `00001KVHR3WRY`。 Requirements / acceptance criteria: - MCP mock server tool appears as model-visible Yoi tool with stable namespaced name。 - Invalid schema is rejected with bounded diagnostic。 - Duplicate/colliding names are rejected fail-closed。 - Server metadata cannot weaken Yoi instructions/scope/permissions。 - No `tools/call` request is sent during registration。 - Tests cover valid registration, pagination/bounds, invalid schema, duplicate/collision, and untrusted metadata normalization。 Escalate if: - Existing `pod::feature` dynamic contribution API cannot register MCP tools without broader provider-substrate changes。 - Schema normalization requires product decisions beyond safe JSON schema subset / bounded diagnostics。 - ToolRegistry registration would force `tools/call` execution into this Ticket。 Next action: - Record `queued -> inprogress` and commit Ticket records before creating the implementation worktree and spawning Coder。 --- ## State changed Ticket body/thread, relation metadata, closed MCP lifecycle dependency, Orchestrator worktree state, visible Pods, existing branch/worktree, and bounded ToolRegistry/schema context were checked. Dependency `00001KVHR3WRY` is closed, no inprogress/capacity blocker 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: `a59e5c1e ticket: accept mcp tool registration`。 - Created implementation worktree `/home/hare/Projects/yoi/.worktree/00001KVHR3WS6-mcp-tool-registration` on branch `impl/00001KVHR3WS6-mcp-tool-registration` at `a59e5c1e`。 - Spawned Coder Pod `yoi-coder-00001KVHR3WS6` 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, `tools/call`, resources/prompts exposure, 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-00001KVHR3WS6`. Implementation commit: - `66fa9d55 mcp: register stdio server tools` Changed areas reported: - `crates/mcp`: - Added MCP `tools/list` protocol result/tool types。 - Added `list_tools_page` and bounded paginated `list_tools_bounded`。 - Added mock-server coverage for paginated `tools/list` and assertion that `tools/call` is not sent。 - `crates/pod`: - Added MCP stdio discovery feature module。 - Resolves configured stdio servers, initializes them, calls bounded `tools/list`, normalizes discovered tools, and registers them through existing protocol-provider / ToolRegistry contribution paths。 - Namespaces tools as stable names like `Mcp__`。 - Rejects invalid schemas and duplicate normalized names with bounded diagnostics。 - Ignores untrusted MCP metadata/annotations/instructions for authority purposes。 - Registered tools are discovery-only and return explicit not-implemented error if invoked; no MCP `tools/call` execution is implemented in this Ticket。 - `package.nix` / `Cargo.lock`: updated for new `pod -> mcp` dependency and refreshed `cargoHash`。 Coder validation reported: - `cargo test -p mcp list_tools --test stdio_lifecycle` - `cargo test -p pod feature::mcp --lib` - `cargo test -p mcp` - `cargo fmt --check` - `cargo check -p pod -p mcp` - `git diff --check` - `nix build .#yoi --no-link` after refreshing stale `cargoHash`。 Known risks / deferrals reported: - MCP tool execution remains intentionally unimplemented; registered discovery-only stubs never send `tools/call`。 - Resources/prompts and `list_changed` handling are deferred。 - Secret-backed MCP stdio env resolution currently passes no Pod secret store from this integration path; non-secret stdio configs are supported by this Ticket。 Orchestrator evidence checked before review dispatch: - Implementation worktree is clean。 - HEAD is `66fa9d55`。 - Diff from acceptance `a59e5c1e..HEAD` is one implementation commit touching 9 files, about 852 insertions / 4 deletions。 - `git diff --check a59e5c1e..HEAD` produced no diagnostics。 Next action: - Dispatch Reviewer for r1 review against Ticket requirements, with focus on ToolRegistry contribution path, schema/name normalization, no `tools/call`, discovery-only invocation behavior, metadata authority boundaries, secret-store deferral, and tests。 --- ## Plan Review dispatch: - Spawned Reviewer Pod `yoi-reviewer-00001KVHR3WS6-r1` against implementation branch `impl/00001KVHR3WS6-mcp-tool-registration`。 - Review target commit: `66fa9d55 mcp: register stdio server tools`。 - Review baseline: `a59e5c1e`。 - Reviewer task focuses on normal ToolRegistry contribution path, untrusted metadata/schema/name normalization, no `tools/call`, discovery-only invocation behavior, no resources/prompts/list_changed registration, diagnostics bounds, secret-store deferral, and tests。 - 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: request changes Verdict: `request_changes` 確認範囲: - Ticket contract / Orchestrator IntentPacket。 - Diff: `a59e5c1e..66fa9d55`。 - 主な対象: `crates/pod/src/feature/mcp.rs`, `crates/pod/src/controller.rs`, `crates/pod/src/feature.rs`, `crates/mcp/src/stdio.rs`, `crates/mcp/tests/stdio_lifecycle.rs`, `crates/mcp/tests/fixtures/mock_server.rs`, `crates/pod/Cargo.toml`, `Cargo.lock`, `package.nix`。 - `tools/call`, resources/prompts registration, `list_changed`/`listChanged` handlingを確認。 Blocking issue: 1. Duplicate/colliding MCP tool names が fail-closed で reject されていない。 - Path: `crates/pod/src/feature/mcp.rs` - `normalize_listed_tools` は最初の normalized name を登録し、後続 duplicate は diagnostic を出して skip するだけ。 - Test `duplicate_names_after_normalization_are_diagnostic_only` はこの挙動を期待している。 - Ticket / IntentPacket は invalid schemas / duplicates / collisions を fail-closed with bounded diagnostics と要求している。 - Server-controlled ordering で衝突する片方が model-visible tool として勝つため、normalized tool identity に対して fail-closed ではない。 Required fix: - Duplicate/colliding normalized names は、少なくとも該当 normalized identity の tool を model-visible にしないこと。 - より安全には、その server contribution/tool set 全体を reject/diagnostic-only にすること。 - Test を更新し、colliding normalized name が model-visible tool として登録されないことを確認する。 Non-blocking concerns / follow-ups: - Acceptance criteria の run-stable schema behavior について、active-run refresh/list_changed mutation は見当たらないが、明示テストはない。可能なら追加するとよい。 - Secret-backed stdio env は integration path が `resolve_stdio_server(..., None)` のため bounded diagnostic で fail し、silent support claim はしていない。これは今回の deferral と整合。 Positive findings: - `tools/list` は initialize 後に `McpStdioClient::list_tools_bounded` 経由で呼ばれる。 - Pagination / tool-count bounds がある。 - `tools/call` execution path は追加されていない。model-visible stub は not-implemented error を返す。 - Resources/prompts は登録されていない。 - Registration は既存 `pod::feature` protocol-provider contribution path を通って Worker/ToolRegistry に入る。 - Server `instructions`, annotations, `_meta`, output schema は authority として使われていない。 - Lifecycle redaction/shutdown behavior は保持されている。 - Nix/Cargo dependency updates は minimal/consistent。 Reviewer validation: - `cargo fmt --check`: passed。 - `git diff --check a59e5c1e..HEAD`: passed。 - `cargo test -p mcp list_tools --test stdio_lifecycle`: passed。 - `cargo test -p pod feature::mcp --lib`: passed。 - `cargo test -p mcp`: passed。 - `cargo check -p pod -p mcp`: passed。 - `nix build .#yoi --no-link`: passed。 Worktree status at review end: clean。 --- ## Implementation report Coder r1-fix report received from `yoi-coder-00001KVHR3WS6`. New fix commit: - `0080c5b3 mcp: reject colliding tool names` Branch commits now: - `0080c5b3 mcp: reject colliding tool names` - `66fa9d55 mcp: register stdio server tools` Fix summary: - Changed duplicate/collision handling in `crates/pod/src/feature/mcp.rs` to fail closed for the normalized tool identity。 - Implementation now normalizes all valid candidate tools first, counts namespaced normalized names, emits bounded duplicate diagnostics, and registers only candidates whose normalized name appears exactly once。 - Server-controlled ordering can no longer cause the first colliding definition to become model-visible。 - Updated test to prove `Mcp_demo_search_files` is not model-visible when produced by two colliding MCP tool names, while unrelated valid `Mcp_demo_unique` still registers。 Coder validation reported as passing: - `cargo fmt --check` - `git diff --check a59e5c1e..HEAD` - `cargo test -p mcp list_tools --test stdio_lifecycle` - `cargo test -p pod feature::mcp --lib` - `cargo test -p mcp` - `cargo check -p pod -p mcp` - `nix build .#yoi --no-link` Remaining deferrals unchanged: - MCP `tools/call` execution remains intentionally unimplemented。 - Resources/prompts and `list_changed` handling remain out of scope。 Orchestrator evidence checked before r2 review: - Implementation worktree is clean。 - HEAD is `0080c5b3`。 - Fix diff from `66fa9d55..HEAD` touches only `crates/pod/src/feature/mcp.rs`, about 43 insertions / 17 deletions。 - Overall `git diff --check a59e5c1e..HEAD` produced no diagnostics。 Next action: - Route back to Reviewer for r2 verification of duplicate/collision fail-closed behavior and final acceptance criteria。 --- ## Review: approve Verdict: `approve` 確認範囲: - Ticket contract / Orchestrator IntentPacket。 - Fix diff: `66fa9d55..0080c5b3`。 - Overall diff: `a59e5c1e..0080c5b3`。 - 主な対象: `crates/pod/src/feature/mcp.rs`、MCP registration boundaries、ToolRegistry contribution path、no `tools/call` / no resources/prompts、bounded `tools/list` pagination、metadata/schema/name normalization、discovery-only stub behavior、Cargo/Nix changes。 Previous blocker verification: - `normalize_listed_tools` は valid candidates を先に構築し、normalized namespaced name を count するようになった。 - count > 1 の names には bounded duplicate diagnostic を出す。 - 登録されるのは normalized name が exactly once の candidate のみ。 - Updated test `duplicate_names_after_normalization_are_not_model_visible` は、`search-files` / `search files` の collision が `Mcp_demo_search_files` を model-visible にしないこと、および unrelated valid `Mcp_demo_unique` は register されることを確認している。 - これにより duplicate/colliding MCP tool names が fail-closed になるという Ticket requirement を満たしている。 Blocking issues: none。 Non-blocking follow-up: - 複数 configured MCP servers 間の sanitized server namespace collision について、将来 explicit coverage を追加してもよいが、この Ticket の discovered-tool name collision acceptance path では blocker ではない。 Reviewer validation: - `cargo fmt --check`: passed。 - `git diff --check a59e5c1e..HEAD`: passed。 - `cargo test -p mcp list_tools --test stdio_lifecycle`: passed, 3 tests。 - `cargo test -p pod feature::mcp --lib`: passed, 5 tests。 - `cargo test -p mcp`: passed, 8 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: `a1f904b8 merge: mcp tool registration` - Implementation commits included: - `66fa9d55 mcp: register stdio server tools` - `0080c5b3 mcp: reject colliding tool names` Reviewer outcome: - r1 requested changes because duplicate/colliding normalized MCP tool names were diagnostic-only and allowed the first colliding definition to become model-visible。 - Coder changed normalization to count all valid names first and register only identities that occur exactly once, plus updated tests。 - r2 approved with no blocking issues。 Orchestrator validation after merge passed: - `cargo fmt --check` - `git diff --check HEAD^1..HEAD` - `cargo test -p mcp list_tools --test stdio_lifecycle` - `cargo test -p pod feature::mcp --lib` - `cargo test -p mcp` - `cargo check -p pod -p mcp` - `nix build .#yoi --no-link` - `nix path-info -S .#yoi`: `113089912` Validation log: - `/run/user/1000/yoi/yoi-orchestrator/bash-output/bash-SnBew4.log` Final state: - Orchestrator worktree clean at `a1f904b8` after validation。 - Implementation worktree remains available for cleanup after Ticket completion records are committed。 - Dashboard/Console refactor is now running in parallel in separate child worktree and is unaffected by this merge。 --- ## State changed Implementation was merged into Orchestrator branch at `a1f904b8`, r2 review approved, and final Orchestrator validation passed: `cargo fmt --check`, `git diff --check HEAD^1..HEAD`, focused `mcp` and `pod feature::mcp` tests, `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 `00001KVHR3WS6` を完了しました。 実装内容: - MCP `tools/list` protocol result/tool types と bounded pagination helper を `crates/mcp` に追加しました。 - MCP stdio discovery feature module を `crates/pod` に追加しました。 - Configured stdio server を initialize し、bounded `tools/list` を呼び、server-provided tool metadata を untrusted data として検証・正規化して ToolRegistry contribution path に登録します。 - Tool names は server namespace を含む stable namespaced name（例: `Mcp__`）に正規化されます。 - Invalid schema、duplicate/colliding normalized names は bounded diagnostics で fail-closed になります。Collision 時は該当 normalized identity は model-visible tool になりません。 - Server metadata / annotations / instructions は Yoi instructions, scope, permissions, system/developer instructions を弱める authority として扱いません。 - Registration は existing protocol-provider / ToolRegistry contribution path を通ります。 - This Ticket は `tools/call` execution を実装していません。Registered discovery-only stub は explicit not-implemented error を返し、MCP `tools/call` は送信しません。 - Resources/prompts/list_changed は実装していません。 主な commit: - `66fa9d55 mcp: register stdio server tools` - `0080c5b3 mcp: reject colliding tool names` - `a1f904b8 merge: mcp tool registration` Review: - r1 は duplicate/colliding normalized MCP tool names が diagnostic-only で fail-closed でないため `request_changes`。 - Coder が collision handling を修正し、該当 identity が model-visible にならない test を追加。 - r2 は `approve`。 最終 validation: - `cargo fmt --check` - `git diff --check HEAD^1..HEAD` - `cargo test -p mcp list_tools --test stdio_lifecycle` - `cargo test -p pod feature::mcp --lib` - `cargo test -p mcp` - `cargo check -p pod -p mcp` - `nix build .#yoi --no-link` Package impact: - `nix path-info -S .#yoi`: `113089912` Validation log: - `/run/user/1000/yoi/yoi-orchestrator/bash-output/bash-SnBew4.log` ---
