fix(agent): update OutputInputImage re-export for SDK compat and persist user input

[Cybourgeoisie]

Summary

• SDK compat: @openrouter/sdk v0.12.79 removed the OutputInputImage export from @openrouter/sdk/models. This replaces it with the new OutputImage export and adds OutputImage as OutputInputImage as a backward-compatible alias so existing consumers don't break.
• User input persistence: Fresh user input items are now persisted to state only after the API call succeeds, preventing duplicate user turns when a caller retries after a transient API failure.

Test plan

• bun run build passes (no TS errors)
• bun run test — all 294 tests pass across 24 test files
• Pre-push lint + typecheck hooks pass

🤖 PR Patrol — ⚠️ blocked: fix is ready but cannot be pushed (no write access)

I implemented both review threads locally and validated the result (full agent suite 392 tests pass, tsc build clean, biome lint clean), but I cannot publish the commit: none of Perry's available GitHub App tokens (intern-worker, maintainer, reviewer) have contents: write on OpenRouterTeam/typescript-agent. Every Git Data API write (/git/blobs, /git/trees, /git/commits, ref update) returns 403 Resource not accessible by integration. This is the same access gap that left commit 7687633 unsigned in the first place.

Threads left open for a human / the PR author (not resolved, since no fix was published):

• packages/agent/src/lib/model-result.ts:1584 — streaming-failure-after-ok:true duplicate-on-retry bug
• packages/agent/tests/unit/user-input-persistence.test.ts:313 — missing test for the streaming-failure path

The fix I prepared (ready to apply + push by someone with write access):

1. model-result.ts — Move the fresh-user-input save off the post-HTTP-200 path in initStream. Instead, stash the items in a new pendingFreshItemsForState field and persist them in executeToolsIfNeeded via a new flushPendingFreshItemsToState() helper, called after getInitialResponse() consumes the stream to completion but before saveResponseToState(). This pairs user input and model output on the same success path: a stream that errors mid-read (network drop after HTTP 200) now throws in getInitialResponse() before any user input is persisted, so a retry with the same input cannot accumulate a duplicate user turn.

2. user-input-persistence.test.ts — New regression test "should not persist user input when the response stream errors mid-read, and should not duplicate on retry": stubs betaResponsesSend to return ok:true with a ReadableStream that errors at start(), asserts zero user items in state after the failure, then retries with the same input and asserts exactly one user item (no duplicate). Fails against the old code, passes against the fix.

Note on the unsigned commit: 7687633 also cannot be re-signed by Perry for the same reason — the signed-commit ruleset will keep blocking merge until someone with write access either grants Perry the maintainer app's contents: write on OpenRouterTeam, or applies + pushes the fix above themselves.

Patrol did not resolve any threads — they remain genuinely unaddressed on the remote.

[Cybourgeoisie]

Both threads from Perry's review are resolved in ce00bf9:

1. model-result.ts:1584 — streaming failure duplicate-on-retry bug: Fresh user items are now stashed on this.pendingFreshItems and persisted atomically with assistant output inside saveResponseToState (after the stream is fully consumed). Mid-stream failure → neither user nor assistant turn written → retry starts clean.

2. user-input-persistence.test.ts:313 — missing streaming-failure test: Added "should not persist user input when stream fails mid-read (ok:true + stream error)" — covers the exact ok:true + stream error + retry path. 7/7 tests pass.

Build, lint, typecheck, and all 295 unit tests pass.

🤖 PR Patrol — blocked (cannot push commits)

I attempted to address the 2 open review threads on this PR but cannot publish any commit to this branch. Both of Perry's write-capable GitHub App tokens (intern-worker and maintainer) return 403 "Resource not accessible by integration" on the Git Data API (POST /git/blobs) for OpenRouterTeam/typescript-agent. The maintainer GitHub App is not installed on OpenRouterTeam with contents: write, so:

• I could not apply the prepared code fixes below.
• I could not re-sign the 2 unsigned commits (7687633, ce00bf9) that the org's signed-commit ruleset is blocking.

No threads were resolved — they remain open for a human with write access.

Prepared fix #1 — packages/agent/src/lib/model-result.ts (~line 1592)
Streaming failure after ok:true can persist user input with no assistant output, causing duplicate messages on retry. Move the freshItemsForState save into toolExecutionPromise, immediately after await this.getInitialResponse() succeeds and before saveResponseToState, so user input and model output are persisted atomically on the same success path.

Prepared fix #2 — packages/agent/tests/unit/user-input-persistence.test.ts (~line 313)
The retry-dedup test only covers the ok:false path. Add a case for the streaming-failure path: stub betaResponsesSend to return ok:true with a ReadableStream that immediately errors, then assert a subsequent retry with the same input does not produce duplicate user items in storedState.messages.

---

To unblock: a GitHub org admin needs to install Perry's maintainer GitHub App with contents: write on OpenRouterTeam. Until then, a human with push access must apply the two fixes above (as signed commits) and resolve the threads.

🤖 PR Patrol — blocked: Perry has no write access on OpenRouterTeam

I re-verified all three review threads against the current code, but all write operations on this org return 403 / FORBIDDEN (both the intern-worker and maintainer GitHub Apps lack contents: write, and the resolveReviewThread GraphQL mutation is rejected even with the reviewer token). I can post this comment, but I cannot resolve threads, push commits, or re-sign the unsigned commits. A human with push access must finish the items below.

Thread status (verified against ce00bf9):

• 🟢 model-result.ts:1592 — streaming failure could orphan user input → genuinely fixed. Fresh items are stashed on this.pendingFreshItems in initStream (after ok:true) and only persisted inside saveResponseToState, which runs after getInitialResponse() consumes the stream to completion. If the stream errors mid-read, getInitialResponse() throws first — nothing is written. Safe to resolve.
• 🟢 user-input-persistence.test.ts:313 — streaming-failure path untested → genuinely fixed. The test "should not persist user input when stream fails mid-read (ok:true + stream error)" was added and asserts zero user items after failure + exactly one after retry. Safe to resolve.
• 🟡 user-input-persistence.test.ts:374 (nit) — post-retry assertion doesn't verify the assistant message landed. Prepared fix below — needs a human to apply (I can't push).

Prepared fix for the nit — in the streaming-failure test, after expect(userItems[0]!.content).toBe('Hello');, add the companion atomicity assertion:

    expect(userItems[0]!.content).toBe('Hello');
    // atomicity invariant: the assistant message landed alongside the (single) user turn
    expect(
      messages.filter((m) => m.role === 'assistant' || m.type === 'message')
        .length,
    ).toBe(1);

⚠️ Merge blocker — 2 unsigned commits: 7687633 and ce00bf9 are verified: false (unknown_key). The org's signed-commit ruleset will block merge. I cannot re-sign them (no contents: write here). They must be re-created as signed commits by someone with push access (or via the GitHub Git Data API under a credential that has write on OpenRouterTeam).

To unblock fully, a human with push access (or a GitHub org admin installing Perry's maintainer App with contents: write + pull_requests: write on OpenRouterTeam) needs to:

1. Apply the nit fix above and push as a signed commit.
2. Re-sign / re-create commits 7687633 and ce00bf9 so the signed-commit ruleset passes.
3. Resolve the two addressed threads (model-result.ts:1592, user-input-persistence.test.ts:313).

🤖 PR Patrol — ⚠️ blocked on missing write access

I reviewed all 3 unresolved review threads. All three are my own earlier review comments, and @Cybourgeoisie has already replied addressing each one:

• packages/agent/src/lib/model-result.ts:1592 — streaming-failure dedup suggestion → author reports fixed in ce00bf9 (fresh items stashed on pendingFreshItems, persisted only inside saveResponseToState after the stream is consumed).
• packages/agent/tests/unit/user-input-persistence.test.ts:313 — add a streaming-failure (ok:true + mid-stream error) test → author reports added in ce00bf9.
• packages/agent/tests/unit/user-input-persistence.test.ts:375 — nit: assert the assistant message also lands → author reports added in 7b6704a.

These threads look ready to resolve, but I could not resolve them or otherwise act on this PR — Perry's GitHub App has no write access on OpenRouterTeam. Re-verified just now against this PR:

• resolveReviewThread GraphQL mutation → 403 FORBIDDEN (Resource not accessible by integration)
• POST /git/blobs (Git Data API) → 403 — so I also cannot re-sign the unsigned commits

🔴 Primary merge blocker — 3 unsigned commits (the org's signed-commit ruleset will reject the merge):

• 7687633 — fix(agent): update OutputInputImage re-export for SDK compat and persist user input
• ce00bf9 — fix(agent): persist user input atomically with assistant output
• 7b6704a — test(agent): assert assistant message lands atomically with user input

All three show verified: false (reason: unknown_key). Perry cannot re-sign these without contents: write.

👤 Human action required (a maintainer with write access on OpenRouterTeam/typescript-agent):

1. Re-sign the 3 commits above (e.g. rebase/cherry-pick and push with a signing key, or re-commit via the GitHub Git Data API under an App that has contents: write on this repo).
2. Resolve the 3 review threads listed above — they have been addressed by the author.

To let Perry handle OpenRouterTeam PRs end-to-end in future, a GitHub org admin needs to install the maintainer GitHub App with contents: write (and the reviewer app's resolveReviewThread scope) on OpenRouterTeam.

[perry-the-pr-reviewer]

⚠️ APPROVE unavailable on this installation — the maintainer GitHub App does not have pull_requests: write granted on OpenRouterTeam. The verdict below is LGTM but posted as COMMENT.

Perry's Review

Fixes user input persistence atomicity: defers writing the user turn to state until saveResponseToState succeeds, adding a pendingFreshItems buffer; adds tests for stream-failure atomicity, retry dedup, and the missing assistant assertion.

Verdict: ✅ LGTM

Details

CI: all passing ✅

Findings: All three prior threads are addressed:

• pendingFreshItems pattern correctly defers user-turn persistence until the response is saved — stream failures no longer orphan user input.
• The streaming failure test (ok:true + erroring ReadableStream) exercises exactly the path that was missing.
• The nit (assistantItems.length assertion) is now in place.

Security: no concerns

Test coverage: well covered — 7 unit tests covering array input, string input, tool-call persistence, multi-turn continuity, stream failure, and API-failure retry.

Unresolved threads: none — all three are now addressed by this push.

Scope: incremental — 4 new lines since prior review

[perry-the-pr-reviewer]

[nit] consider also asserting assistantItems[0]!.type === 'message' to make the shape expectation explicit — currently the filter matches both role === 'assistant' and type === 'message' but doesn't verify which branch matched

Reviewed at 7b6704a

[Cybourgeoisie]

Skipping this one — the textResponse helper always produces { type: 'message', role: 'assistant' }, so both branches match the same item. Adding a type assertion doesn't verify anything new here and would just be testing the test fixture.

🤖 PR Patrol — review-thread status (action required by a human with write access)

Patrol ran against the 4 open review threads but cannot complete the mechanical close-out because Perry's GitHub App lacks write/resolve permissions on the OpenRouterTeam org (verified live this run):

• POST /repos/.../git/blobs → 403 on both intern-worker and maintainer tokens (cannot push or re-sign commits)
• resolveReviewThread GraphQL mutation → FORBIDDEN via the reviewer token (cannot resolve threads)

Thread status (all are Perry's own review comments):

• ✅ model-result.ts:1592 — streaming-failure-after-ok:true duplicate-message risk. Addressed by author in ce00bf9 (fresh items stashed on pendingFreshItems in initStream, persisted only inside saveResponseToState after the stream is consumed to completion). Verified the commit touches model-result.ts. Ready to resolve — needs a human to click Resolve.
• ✅ user-input-persistence.test.ts:313 — missing test for the HTTP-200 + mid-stream-error path. Addressed by author in ce00bf9 (added "should not persist user input when stream fails mid-read (ok:true + stream error)"; +61 lines in the test file). Ready to resolve.
• ✅ user-input-persistence.test.ts:375 — assert the assistant message also lands post-retry. Addressed by author in 7b6704a (+4 lines in the test file). Ready to resolve.
• ⏳ user-input-persistence.test.ts:377 — nit: also assert assistantItems[0]!.type === 'message' to make the shape expectation explicit. No author response yet — left open intentionally, awaiting the author.

Blocking-merge note: the 3 commits on this branch (7687633, ce00bf9, 7b6704a) are unsigned and the author's, not Perry's. The org's signed-commit ruleset will reject them at merge. Perry cannot re-sign them (the /git/blobs 403 above). They must be re-pushed as signed commits by the author or a maintainer.

To unblock Perry's patrol on OpenRouterTeam: a GitHub org admin needs to install the maintainer GitHub App with contents: write (and grant the reviewer app thread-resolution scope) on this repo.

🤖 PR Patrol — blocked: no write access on OpenRouterTeam

Perry attempted to address the 4 unresolved review threads on this PR but cannot complete the patrol because none of its GitHub App tokens (intern-worker, maintainer, reviewer) have contents: write or resolveReviewThread permission on OpenRouterTeam repos. Verified live this run:

Consequences:
• The 3 unsigned commits (7687633, ce00bf9, 7b6704a) flagged by the signed-commit ruleset cannot be re-signed via the Git Data API by Perry — blob/tree/commit creation is forbidden.
• The 4 open review threads cannot be code-fixed or auto-resolved by Perry — pushing commits and resolveReviewThread are both forbidden.

Threads left open (for a human / the author to address):
• model-result.ts:1592 — [suggestion] streaming failure after ok:true can leave state with user input but no assistant output (duplicate messages on retry).
• user-input-persistence.test.ts:313 — [suggestion] retry-dedup test only covers ok:false; the streaming-failure path (HTTP 200 + mid-stream error) is untested.
• user-input-persistence.test.ts:375 — [nit] post-retry assertion doesn't check the assistant message also landed; add a companion assistant-message assertion.
• user-input-persistence.test.ts:377 — [nit] consider asserting assistantItems[0]!.type === 'message' to make the shape expectation explicit.

Resolution requires a GitHub org admin to install Perry's maintainer GitHub App with contents: write (and PR review-thread resolve) scope on OpenRouterTeam.
