Records an anonymous mcp.tool.invoked event (tool name, calling driver kind) for every T3 MCP tool call, and an mcp.agent.delegated event for delegate_task, create_threads and t3_thread_launch that relates the calling driver/model to the target driver/model.

🟡 Medium telemetry/ProviderDimensions.ts:53
crossProvider is reported as true when either selection cannot be resolved, even if both selections refer to the same driver. A missing caller snapshot becomes "unknown", which differs from the target's driver label and biases delegation-pattern counts; only compare providers when both selections resolve.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This is a substantial production feature that adds always-on telemetry around MCP calls and a background delegated-task event stream, including thread/provider lookups and new outbound analytics data. Unresolved comments identify telemetry-dimension accuracy gaps and an architectural concern about where the instrumentation belongs. Not approved because:

Move launch analytics out of the transport handler.
recordLaunch loads providers and records analytics in the toolkit handler. Put this step in a domain service method for MCP thread launches, and let the handler call that method. As per coding guidelines, “A transport handler does three things: decode the request, call one service method, and map the service's typed errors to the transport's error. Nothing else.”

Use the explicit thread target for sequence-only handoffs.
When t3_queue_edit, t3_queue_promote_to_steer, or t3_pending_request_respond succeeds with a different threadId, its handler returns only { sequence }. The wrapper finds no target in the result, so agentToolProperties emits mcp.tool.invoked without the receiving thread’s provider/model or crossProvider dimensions. These tools are included in HANDOFF_TOOLS; use the explicit threadId as a fallback only for these tools, successful calls, and results without a target ID.

Effect 4.0.0-rc.115 unstable ai Tool MCP registerToolkit parameters schema validation handler payload
💡 Result:
`McpServer.registerToolkit` **publishes the tool’s parameter schema to MCP and forwards the incoming arguments as the handler payload**. In the current source, it builds the MCP `inputSchema` from `Tool.getJsonSchema(tool)`, then passes `payload` directly to `built.handle(tool.name, payload)`. ([github.com](https://github.com/Effect-TS/effect-smol/blob/main/packages/effect/src/unstable/ai/McpServer.ts))
For **schema validation**, the key distinction is the tool’s parameter definition: an Effect `Schema` gives typed, validated parameters; raw JSON Schema exposes the shape but does **not** validate the handler input. ([effect.website](https://effect.website/docs/v4/api/effect/ai/Tool)) The MCP registration code itself doesn’t visibly decode/validate the payload before forwarding it; validation is handled by the toolkit/tool path when using Effect Schemas.
**Version caveat:** I found current v4 docs/source, but not a source pinned specifically to `4.0.0-rc.115`, so I can’t confirm every detail was identical in that release. The closest sources are the current [`registerToolkit` implementation](https://github.com/Effect-TS/effect-smol/blob/main/packages/effect/src/unstable/ai/McpServer.ts) and [Tool API reference](https://effect.website/docs/v4/api/effect/ai/Tool).

Effect-TS effect-smol tag 4.0.0-rc.115 packages/effect/src/unstable/ai/Toolkit.ts handle schema decode parameters validation MCP
💡 Result:
For **`effect@4.0.0-rc.115`**, the exact versioned behavior of `Toolkit.ts` is **not verified by the sources I found**: the accessible `Toolkit.ts` is on the current `main` branch, not pinned to rc.115. The rc.115 release page is available, but doesn’t establish this implementation detail. ([github.com](https://github.com/Effect-TS/effect/blob/main/packages/effect/src/unstable/ai/Toolkit.ts))
What the nearby MCP source does establish: `McpServer.callTool` looks up the tool by name and passes `request.arguments` to its handler. `registerToolkit` builds the toolkit, then registers each tool with its JSON Schema. This shows schema publication and argument handoff, but **does not by itself establish where—or whether—runtime schema decoding/validation occurs**. ([github.com](https://github.com/Effect-TS/effect-smol/blob/main/packages/effect/src/unstable/ai/McpServer.ts?utm_source=openai))
So the key point is: **MCP receives a schema and forwards arguments; confirm parameter decoding in the tool handler path before assuming MCP validates them.** The current source is the closest relevant reference, but its version differs from the requested tag. ([github.com](https://github.com/Effect-TS/effect-smol/blob/main/packages/effect/src/unstable/ai/McpServer.ts?utm_source=openai))

Effect-TS effect 4.0.0-rc.115 McpServer.ts Tool.ts Toolkit.ts GitHub raw decodeUnknown Effect Schema handler
💡 Result:
For **Effect `4.0.0-rc.115`**, these are the exact-tag GitHub raw sources:
- [McpServer.ts](https://raw.githubusercontent.com/Effect-TS/effect/effect%404.0.0-rc.115/packages/effect/src/unstable/ai/McpServer.ts)
- [Tool.ts](https://raw.githubusercontent.com/Effect-TS/effect/effect%404.0.0-rc.115/packages/effect/src/unstable/ai/Tool.ts)
- [Toolkit.ts](https://raw.githubusercontent.com/Effect-TS/effect/effect%404.0.0-rc.115/packages/effect/src/unstable/ai/Toolkit.ts)
In `McpServer.ts`, `callTool` delegates to the internal tool registry, and registered tool handlers receive `call.arguments`. The MCP server maps invalid tool input to `InvalidParams`. ([raw.githubusercontent.com](https://raw.githubusercontent.com/Effect-TS/effect/effect%404.0.0-rc.115/packages/effect/src/unstable/ai/McpServer.ts))
The raw sources above are pinned to **rc.115**. The search excerpt showing `Schema.decodeUnknownEffect` was from a different, current source view, so it does **not** establish which exact decoding call rc.115 uses; inspect `Tool.ts` and `Toolkit.ts` at the pinned tag for that detail.

Whitelist delegate_task.mode and t3_thread_launch.workspaceStrategy.type in telemetry.
Rejected tool calls still emit settings. The telemetry wrapper records the original payload on every exit, and handoffSettings copies these two strings into mcp.tool.invoked. A rejected call can therefore place arbitrary text in the anonymous event.
t3_thread_send.delivery comes from the tool result, not its arguments. Its success schema restricts it to closed literals, so it does not need this guard.
Suggested fix

In handoffSettings, whitelist delegate_task’s mode to the supported values async
and wait, mapping any other supplied string to a safe fallback. Apply the same
allowlist approach to t3_thread_launch’s workspaceStrategy.type, permitting
root, existing_worktree, and worktree; preserve the existing defaults when
values are absent and leave t3_thread_send.delivery unchanged.
