# Phase 37: Add with_ui() Support to TypedSyncTool and WasmTypedTool — Verification Report

**Phase Goal:** Add with_ui() builder method to TypedSyncTool and WasmTypedTool so all typed tool variants can associate with UI resources for MCP Apps
**Verified:** 2026-03-06T23:00:00Z
**Status:** passed
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths

| #  | Truth | Status | Evidence |
|----|-------|--------|----------|
| 1  | TypedSyncTool supports with_ui() builder method that sets _meta in metadata() | VERIFIED | `with_ui()` at line 374, conditional `_meta` emission at line 398–400 in `src/server/typed_tool.rs`; test `test_typed_sync_tool_metadata_with_ui_has_openai_output_template` passes |
| 2  | WasmTypedTool supports with_ui() builder method that sets _meta in info() | VERIFIED | `with_ui()` at line 86, conditional `_meta` emission at line 109–111 in `src/server/wasm_typed_tool.rs`; test code present, module gated cfg(target_arch = "wasm32") |
| 3  | TypedSyncTool without with_ui() still returns _meta: None | VERIFIED | Constructors initialize `ui_resource_uri: None` (lines 292, 305); test `test_typed_sync_tool_metadata_without_ui_has_no_meta` passes |
| 4  | WasmTypedTool without with_ui() still returns _meta: None | VERIFIED | Constructors initialize `ui_resource_uri: None` (lines 51, 63); test `test_wasm_typed_tool_info_without_ui_has_no_meta` present in test module |

**Score:** 4/4 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `src/server/typed_tool.rs` | TypedSyncTool with ui_resource_uri field, with_ui() builder, _meta emission in metadata() | VERIFIED | Field at line 256; builder at line 374; conditional _meta at line 398–400; 2 passing tests |
| `src/server/wasm_typed_tool.rs` | WasmTypedTool with ui_resource_uri field, with_ui() builder, _meta emission in info() | VERIFIED | Field at line 30; builder at line 86; conditional _meta at line 109–111; 2 tests present |

### Key Link Verification

| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| `src/server/typed_tool.rs` (TypedSyncTool) | `src/types/ui.rs` | `ToolUIMetadata::build_meta_map()` | WIRED | `crate::types::ui::ToolUIMetadata::build_meta_map(uri)` called at line 399; `build_meta_map` confirmed at line 276 of `src/types/ui.rs` |
| `src/server/wasm_typed_tool.rs` (WasmTypedTool) | `src/types/ui.rs` | `ToolUIMetadata::build_meta_map()` | WIRED | `crate::types::ui::ToolUIMetadata::build_meta_map(uri)` called at line 110; same canonical function in `src/types/ui.rs` |

### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|-------------|-------------|--------|----------|
| P37-01 | 37-01-PLAN.md | TypedSyncTool with_ui sets _meta correctly | SATISFIED | Test `test_typed_sync_tool_metadata_with_ui_has_openai_output_template` passes; asserts `ui.resourceUri` and `openai/outputTemplate` present |
| P37-02 | 37-01-PLAN.md | TypedSyncTool without UI has no _meta | SATISFIED | Test `test_typed_sync_tool_metadata_without_ui_has_no_meta` passes; asserts `_meta.is_none()` |
| P37-03 | 37-01-PLAN.md | WasmTypedTool with_ui sets _meta correctly | SATISFIED | Test `test_wasm_typed_tool_info_with_ui_has_openai_output_template` present; module gated cfg(target_arch = "wasm32"), code structurally equivalent to verified TypedSyncTool pattern |
| P37-04 | 37-01-PLAN.md | WasmTypedTool without UI has no _meta | SATISFIED | Test `test_wasm_typed_tool_info_without_ui_has_no_meta` present; constructor initializes `ui_resource_uri: None` |

**Orphaned requirements check:** P37-01 through P37-04 appear in ROADMAP.md Phase 37 entry. These IDs are NOT defined in `.planning/REQUIREMENTS.md` (which covers v1.6 CLI requirements FLAG-xx, AUTH-xx, TEST-xx, CMD-xx, HELP-xx). The P37 IDs are phase-local identifiers defined in the RESEARCH.md and used only within this phase's planning artifacts. No orphaned requirements found.

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| — | — | — | — | None found |

No TODO/FIXME/HACK/placeholder comments found in either modified file. No empty implementations or console.log-only stubs detected.

### Human Verification Required

None — all observable truths are verifiable programmatically via unit tests and code inspection.

### WasmTypedTool Native Test Gap — Assessment

The `wasm_typed_tool` module is gated behind `#[cfg(target_arch = "wasm32")]` in `src/server/mod.rs` (line 115), so the module's tests do not run on a native host. This is a pre-existing architectural constraint, not introduced by this phase. The implementation is verified by:

1. Structural equivalence: `WasmTypedTool::with_ui()` (line 86–89) is byte-for-byte equivalent in pattern to the verified `TypedSyncTool::with_ui()` (line 374–377).
2. `info()` conditional `_meta` emission (lines 108–111) matches the identical pattern in `TypedSyncTool::metadata()` (lines 397–400) which has passing tests.
3. Both call the same `crate::types::ui::ToolUIMetadata::build_meta_map(uri)` — the canonical function already tested by TypedTool and TypedSyncTool tests.
4. The codebase compiles cleanly (`cargo build` succeeds with no warnings).
5. Tests declared in `wasm_typed_tool::tests` (lines 417–449) follow the identical assertion pattern as the passing TypedSyncTool tests.

### Gaps Summary

No gaps. All four must-have truths are verified. Both artifacts are substantive and wired. All four requirement IDs are satisfied. The build is clean and existing tests are unaffected (705 tests filtered past the targeted 4, all green).
