fix(server): analytics record the thread binding a scheduled task actually got by only21mil · Pull Request #28761 · pingdotgg/t3code

only21mil · 2026-11-01T16:56:17Z

Problem

The mcp.tool.invoked analytics event for schedule_task reports bindToCurrentThread: true whenever the agent leaves that argument out, so unbound tasks were counted as bound. Rejected and failed calls also reported true, even though nothing was saved.

Change

handoffSettings now reads the binding from the saved task the tool returns (boundThreadId set or null), for both create and update. A failed call, or one with no result, records no binding instead of a guessed one. Only a boolean is recorded, and scheduling behavior is unchanged.

Scope

A bug fix for wrong data in an existing metric. It is a small, focused fix for an obvious bug, so it needs no issue. It adds no feature and no new field; it corrects the value of the bindToCurrentThread setting that #15913 introduced.

Verification

To see it on Linux (server):

Run a T3 server with T3CODE_POSTHOG_HOST pointed at a local recorder and a fake key.
Have an agent call schedule_task for another project without bindToCurrentThread; the task saves unbound.
The recorded event says bindToCurrentThread: true on main and false on this branch.

Real server runs on main at e63d80a (before), this branch at ccca0ca (after), and their local merge at cf2953fc26 (clean merge, not pushed), with a real Codex thread (codex-cli 0.167.1, gpt-6-luna) making four schedule_task calls and an outside MCP client a fifth. Recorded bindToCurrentThread, main vs branch and merge:

create in app-b, argument omitted, saved unbound: true vs false
update of that task, argument omitted, still unbound: true vs false
create in app-b with true, rejected: true vs no binding
create in app-a, argument omitted, saved bound: true vs true
client call with no thread, rejected: true vs no binding

All three runs saved the same tasks with the same bindings. No screen shows this value, so the evidence is text.

Re-checked against main f419698 on 2026-11-12: ProviderDimensions.test.ts fails with that main's ProviderDimensions.ts (bindToCurrentThread true where false is expected) and passes with this change, the branch merges cleanly with that main, and the same five calls on that main still record true for all five.

Not checked: the real PostHog ingest. The recorder accepts every batch, so this shows what the server sends, not how PostHog stores it.

Unedited run output: main, branch, merge. Each "recorded" line keeps the event's tool, caller, outcome and binding fields; platform and version fields are left out.

The mcp.tool.invoked analytics event for schedule_task reports bindToCurrentThread: true whenever the agent leaves that argument out. The server does not work that way. With the argument omitted, a new task binds only when the caller is a thread in the same project, and an update keeps the task's existing binding. So unbound tasks were counted as bound. Rejected and failed calls also reported true, even though nothing was saved.

handoffSettings now reads the binding from the saved task the tool returns (boundThreadId set or null), for both create and update. A failed call, or one with no result, records no binding instead of a guessed one. Only a boolean is recorded. The thread id never reaches analytics. Scheduling behavior is unchanged; only the telemetry helper changed.

This is a small, focused fix for an obvious bug in an existing metric, which fits the obvious-bug exception in CONTRIBUTING. It adds no feature and no new field. It corrects the value of the bindToCurrentThread setting that #15913 introduced.

I ran the same steps through the real server on main at e63d80a (before), this branch at ccca0ca (after), and their local merge at cf2953fc26 (clean merge, not pushed).

Each revision ran its own T3 server from source in a sandbox ("Test machine"), with its own home and synthetic projects app-a and app-b. Telemetry was on, with T3CODE_POSTHOG_HOST pointed at a local recorder and a fake key, so the server's real /batch/ requests were captured and went nowhere else.
A real Codex thread (codex-cli 0.167.1, gpt-6-luna) in app-a made four schedule_task calls through the server's MCP endpoint. An outside MCP client with no thread made a fifth.
Recorded bindToCurrentThread, main vs branch and merge:
- create in app-b, argument omitted, saved unbound: true vs false
- update of that task, argument omitted, still unbound: true vs false
- create in app-b with true, rejected: true vs no binding
- create in app-a, argument omitted, saved bound: true vs true
- client call with no thread, rejected: true vs no binding
All three runs saved the same two task titles with the same thread bindings, so scheduling did not change.
The case added to ProviderDimensions.test.ts failed on main and passes with the fix (regression cover). vp run check:changed passed on ccca0ca.

Approvability

Verdict: Approved at ccca0ca

Macroscope's review found this PR approvable — Scheduled-task analytics now report the binding actually saved, omitting the field when no binding result is available. Scheduling behavior is unchanged, and only a boolean—not the thread ID—reaches analytics.

Walkthrough

The schedule_task telemetry setting now uses the saved result’s boundThreadId instead of the tool input. Tests cover a null binding and an orchestrator failure.

Changes: Schedule task telemetry

Layer / File(s)	Summary
Derive binding telemetry from saved result `apps/server/src/telemetry/ProviderDimensions.ts`, `apps/server/src/telemetry/ProviderDimensions.test.ts`	The setting is `false` when the saved `boundThreadId` is null and `true` when it is a string. Other values produce no setting. Tests cover a null binding and an orchestrator failure.

Estimated code review effort: 2 (Simple) | ~5 minutes

Full details: Description check

Explanation

The description follows the template's main sections: Problem, Change, Scope, and Verification. It states the bug (schedule_task reports bindToCurrentThread true when the argument is omitted, and rejected or failed calls also report true), the fix (the binding is read from the saved task's boundThreadId, and failed or no-result calls record no binding), and the scope (a small bug fix that needs no issue, and it corrects the setting from #15913). Verification is detailed: it gives before/after runs on main, the branch, and the merge, a regression test that fails on main and passes with the fix, and the vp run check:changed result. It also states what was not checked (the real PostHog ingest and the end-to-end MCP call through a running server with analytics capture). The template asks for focused tests and observed results, which are present. The description is long and repeats some content between the top sections and the details block, and it does not use a conventional commit title, which the template's header asks for. These are minor gaps, so the check passes.

Cover the bound scheduled-task case in the telemetry test.

The new test checks only a null boundThreadId and a failed result. No case passes a string boundThreadId on a successful schedule_task result. The implementation maps a string value to bindToCurrentThread: true. A regression that returns false for bound tasks, or omits the setting for them, would still pass this test. Add the bound case to the same it block.

Note

🤖 Opus 5.5 replying on behalf of Victor.

The CodeRabbit nitpick on ProviderDimensions.test.ts (add a bound schedule_task case) does not point at a defect. The bound case already records true through the real server: in the run in the description, a create in the calling thread's own project with bindToCurrentThread omitted saved the task bound to that thread and recorded bindToCurrentThread: true on ccca0ca and on its local merge with main e63d80a (agent call 4 in the run output). I'm leaving the test as it is so the head does not change.

Verified in a real dev environment

verified as-is at ccca0cac2a1e37b51b69d03dbed8064f905c0f87 on a linux boat vm. reproduced the bug first on github/main at 9c7f6ebf315883fdd7f76fad45ca623c15caaefc in a separate worktree. installed dependencies with vp i on both revisions and ran one background dev server at a time.

i used repo playwright with /usr/bin/google-chrome, added two real git projects through the web ui, selected codex gpt-6.1-sol, and submitted the same five-case prompt on both revisions. real provider MCP calls created/updated paused tasks. captured the server's actual /batch/ telemetry requests with a local receiver and compared them with tool results and read-only saved task rows.

bindToCurrentThread in captured mcp.tool.invoked events, main -> pr:

cross-project create, argument omitted, saved unbound: true -> false.
update that unbound task, argument omitted: true -> false.
cross-project explicit binding rejected: true -> absent.
same-project default binding: true -> true; saved binding still points to the calling thread.
explicit false: false -> false; task stays unbound.

both revisions saved the same three task titles and binding states. every saved task remained disabled with no next run. the bound thread id did not appear in analytics properties.

command and captured-event transcript

these app captures show unchanged scheduling results; the transcript proves the telemetry correction.

vp test run apps/server/src/telemetry/ProviderDimensions.test.ts passed through blacksmith-check: 1 file, 3 tests. the pr reported 31 successful checks, zero failing or pending. no code changes or pushes were needed.

Not verified

real posthog ingestion/storage, native desktop/mobile clients, scheduled execution (tasks were deliberately paused), and a handler throwing without a result were not exercised. this is a server telemetry change with no visible ui change, so the runtime transcript is the before/after proof.

an initial pr launch selected the default shared home. i stopped it and repeated the complete pr verification with an explicit isolated home; those initial events are excluded from the evidence.

Note

🤖 Opus 5.5 replying on behalf of Victor.

@maria-rcks thanks for running the five cases through a real Codex thread on main and this head; your results match mine.

"A handler throwing without a result" is a case this PR changes. When the handler fails, the server passes no result to the telemetry helper. On main that event records bindToCurrentThread: true when the argument is omitted; on this branch it records no binding. The direct-call output in the description's details block shows it ("handler threw (no result)": before {"bindToCurrentThread":true}, after {}), and I ran the helper at ccca0ca again for each argument value:

handler threw, bindToCurrentThread omitted -> recorded settings: {}
handler threw, bindToCurrentThread=true -> recorded settings: {}
handler threw, bindToCurrentThread=false -> recorded settings: {}

The other three items are outside this diff, which changes only the server's telemetry helper and its test.
