Problem

watch_pull_request wakes its thread for every kind of change, so an agent watching a PR for review feedback still spends a turn on each passed check and conflict.

Change

watch_pull_request takes an optional events list: comment, review (inline review comments included), checks_failed (approval holds included), checks_passed, no_checks and conflict. The watch still records every change, but wakes and counts toward the comment-only limit only for the selected ones. A read made under an older selection is dropped and read again. Omitting events keeps today's behavior.

A close without merging, and 8 reads in a row that find the PR missing or inaccessible, still wake the agent; a merge still ends the watch silently. The tool description now says "unmerged close/unreadable", and the tool list stays at main's size (mcpToolListJsonBytes 48217).

Scope and approval

This configures the existing PR watch from #15057 by t3dotgg. The watcher already detects these six change kinds; events only chooses which of them wake the thread. Recording, ending and settlement are unchanged. There is no issue or prior maintainer approval, so two choices are for you to confirm: omitting events on an existing watch resets it to all changes (#24721 by nateEc proposes includeOwnRemarks, a separate option on the same watch, and takes the opposite approach), and inline review comments belong to review. #21628 by juliusmarminge narrows watched-thread reads and does not filter wakes.

Verification

Live run against a real GitHub PR, main d313b2a vs 674a7fb (docs-only since 6d3fec7; the head since changes only the tool text and an eval case), Linux. Two isolated servers; each thread called watch_pull_request through T3's MCP with the events in its name (a scripted ACP agent, no model turns). A GitHub Actions identity posted the comments and reviews. Events (UTC): checks passed at watch start, comment 15:16, review 15:23, inline review comment 15:27, check failed 15:31, checks passed 15:37, conflict 15:41, no checks after a [skip ci] push (16:01/16:03), closed 16:05. A comment from the PR author and the conflict resolution woke nobody on either build. Wakes read back from each server's database:

This PR's tests (pullRequestWatch.test.ts, runtimeLayer.test.ts, handlers.test.ts) run against main's source (0a9abdd) give 6 failed | 167 passed (173): the event filter, the four stale-selection races and the watch handler. On this head they give 173 passed (173).

mcp-tool-use ran free on our own CLIProxyAPI accounts, with GPT-6.1 Sol (xhigh) as the agent and GPT-6.1 Terra as the shell. The new filtered-watch-merge-no-wake case asks for cleanup after a merge under a comment-only watch, ending with a Cleanup trigger: line. Old text: "Cleanup trigger: T3’s existing PR watch wakes this thread when #124 closes, and I confirm it was merged." This text: "Cleanup trigger: Your message confirming #124 has merged." The strict grader also failed one correct new-text answer because it added a second clause. The other 26 Codex-runnable watch cases are shown with the 100% rows filtered out (grade at run time, then now):

$ pnpm mcp-tool-use:regrade runs/old-text-new-case/results.jsonl | grep '^| filtered'

vp run check:changed passes. The body runs past 2,500 characters because of the live-run setup and the two transcripts.

Not checked:

• A live merge ending a filtered watch, approval holds, the comment-only wake limit and a filter change during a read; focused tests cover them. The live run above used a scripted agent, not provider turns.
• mcp-tool-use on Claude models (needs a per-token key), and the full suite the evals README asks for before merge.
• Other forge deployments or deployed relay/tunnel environments. Filtering uses shared change kinds after host reads.
• Native clients, full builds and full test suites.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This adds opt-in PR-watch event filtering across shared contracts, orchestration, reactor caching, and wake evaluation, changing which existing changes trigger agent turns and adding concurrency coordination. Existing callers retain the all-events behavior, but the cross-component runtime scope is broader than a small self-contained option.

Walkthrough

Pull-request watches now accept optional event filters. The server carries selections through watch commands and synchronization, filters reported changes by selection, and continues updating watch state from detected changes.

Changes: Pull-request watch event filters

The only red check is Agent context budget, and it needs the agent-context-increase label to pass: the new events parameter grows the MCP tool list by 255 bytes against current main (mcpToolListJsonBytes 48116 to 48371), all on watch_pull_request.

Trimming can't remove it. 148 of those bytes are the parameter's schema: the six wake kinds and minItems: 1, which rejects an empty filter. The other 107 are its description, which tells agents the default is every change and that a closed PR or a watch T3 ends still wakes them. Getting to zero would mean cutting existing watch_pull_request guidance from main.

The branch's only conflict with main is agentContextBudget.json. Its value after a merge is 48371.

[only21mil]

Note

🤖 Opus 5.5 replying on behalf of Victor.

The agent-context-increase label is no longer needed, so please ignore my earlier request. The new events field no longer has its own description, since its enum names the six wake kinds, and the watch_pull_request description is 148 bytes shorter. Together that covers the 255 bytes the field added. The MCP tool list is back at main's size (mcpToolListJsonBytes 48116), and Agent context budget passes. Current main is merged in, which also cleared the budget-file conflict.

Verified in a real dev environment

verified as-is at 4f57754e45c6b4a7969c1db3ca9a239a71c9851d on a linux boat vm. no code changes or pushes.

ran main 2922e8fb59 in a separate worktree first, then the exact pr head, with dependency installs and only one dev server at a time. used isolated app state, real projects pointing at the git checkouts, real github reads of this pr, and codex gpt-6.1-sol turns. no mocks, fixtures, or fabricated host events. drove the web composer with the repo's playwright and google chrome.

• main has no events parameter. supplying a review-only selection through mcp still produced a real provider wake for passed checks and a merge conflict.
• on this head, a review-only watch recorded passed: true, conflicting: true, and the real head sha, while the thread stayed at one run. widening it by omitting events preserved startedAt and those observations, without replaying them.
• in the web client, asked codex to watch only conflicts. codex registered that filter; the reactor recorded passed checks silently and delivered only the conflict. codex replied conflict.
• an unfiltered neighboring thread still received passed-check and conflict notifications. an empty events list was rejected. the web Stop control removed the conflict watch; mcp unwatch removed the other watches.

short runtime transcript from persisted server state and real provider replies:

main / supplied events=[review]
  notification: #24981: checks passed, merge conflict
pr / events=[review]
  watch: passed=true conflicting=true wakes=0
  provider runCount: 1
pr / same watch widened to all
  provider runCount: 1; startedAt unchanged
pr / events omitted on a new watch
  notifications: #24981: checks passed; #24981: merge conflict
pr / events=[conflict], requested in web composer
  notification: #24981: merge conflict
  provider reply: conflict
pr / events=[]
  -32602: Expected a value with a length of at least 1 at [events]

some cli-created codex turns immediately unwatched because their injected instructions require it at handback. reactivated those watches through an authenticated mcp session to observe the reactor. the web-created conflict request stayed active through its notification.

blacksmith: 45 existing evaluator/handler tests passed, plus all four current-events-selection race cases. ci at this sha reports 22 successful checks, six skipped checks, and one cancelled native fingerprint job.

20-second recording of the web request and real codex watch registration:

later screenshot showing the selected conflict notification and codex reply:

Not verified

live review/comment delivery, failed-check and no-check events, terminal close/merge handling, and a live in-flight filter-change race. did not manufacture activity or mutate the pr to trigger them; the focused tests cover filtering and stale-read cases. native desktop/mobile, other providers, and relay/tunnel connections were not exercised on this linux vm. no merge-readiness claim: the app reports a merge conflict.

Note

🤖 Opus 5.5 replying on behalf of Victor.

Thanks, Maria, for running this end to end with real provider turns. That is the part our own verification could not check, since the reactor tests mock the host.

Your run matches the behavior the description claims:

• On main, a review-only selection still woke for passed checks and the conflict. On this head the same watch recorded both silently, and the thread stayed at one run.
• Widening by omitting events kept startedAt and the recorded state without replaying it.
• A conflict-only watch requested from the web composer delivered only the conflict. An unfiltered neighboring thread still got every wake, and events: [] was rejected.

On what you left unverified: live review and comment delivery, failed-check and no-check wakes, close and merge handling, and a live filter-change race are covered only by the focused tests (the four Deferred-controlled race cases cover the last one). The merge conflict comes from main moving after our last merge. If you want the branch updated, say so and we will merge main in one merge commit, with no rebase.

[only21mil]

Note

🤖 Opus 5.5 replying on behalf of Victor.

The branch now includes current main through one merge commit, 6d3fec7, with no rebase. This clears the conflict. Nothing was dropped, since main covers no part of this PR.

The conflict came from #24599, which reports checks waiting for a maintainer's approval as their own change instead of a failed check. The merge maps that change to checks_failed, so a checks_failed watch still wakes for it as before, and adds that case to the evaluator filter test. The paths in your run (review-only and conflict-only watches, passed checks, widening by omitting events, and the empty list) are unchanged by the merge.

On the merged head, vp run check:changed passes, the watch, runtime-layer, MCP and provider suites pass (1375 tests), and the tool list is still main's size. The description has the matching updates.

@maria-rcks thanks again for your run. The items it left unverified (live comment and review delivery, failed-check and no-check wakes, close) now have a live run against a real GitHub PR on main d313b2aff3 and this head 674a7fbde8: each filtered watch woke only for its own event kind plus the close, an inline review comment counted as review, and on main every watch woke for all nine events. The wake log is in the description; a live merge ending a filtered watch, approval holds and the comment-only wake limit are still unverified.

🤖 Opus 5.5 replying on behalf of Victor.

@maria-rcks Since your verification at 4f57754e45, the watch code changed only in the main merge 6d3fec7e6c (main's new awaiting-approval change maps to checks_failed, as described above); after it, 31be2ccb1a and 674a7fbde8 edit docs/user/source-control.md, and 20f9f8777f changes the watch_pull_request description's wake list from "close/T3 watch end" to "unmerged close/unreadable" and adds a filtered-watch-merge-no-wake eval case. That case fails on the old description and passes on the new one, and CI passes on this head.
