fix(task): bound the auto-approval retry loop in attemptApiRequest#1324jsboige wants to merge 1 commit into
Conversation
The autoApprovalEnabled path of attemptApiRequest recursed with no cap — only abort stopped it. On a persistent API error (e.g. HTTP 429 fair usage, a whole-account rate limit), each retry is charged against the account and worsens the condition; observed 17 retries (~2h50) and 48 (~8h) in production. Add MAX_AUTO_APPROVAL_RETRIES = 3 (same convention as MAX_CONTEXT_WINDOW_RETRIES) checked before backoffAndAnnounce so the refused request never sleeps on a backoff that cannot succeed, and stop loudly with an Error naming the cap and the last underlying error. The context-window and interactive retry paths are untouched. Add a mutation-checked spec: always-failing stream + autoApprovalEnabled must throw after MAX+1 total attempts; the in-mock guard fails fast if the cap is removed.

📝 WalkthroughWalkthroughAuto-approval now allows one initial request and up to three retries after persistent first-chunk API failures. The task then throws an error that includes the retry cap, issue reference, and underlying API error. Tests cover the retry and backoff counts. ChangesAuto-approval retry cap
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The retry limit can still be bypassed in the full task execution flow, allowing additional API requests after the configured cap and potentially prolonging persistent failures. Merge should wait until the capped error is terminal across that path. Sequence Diagram(s)sequenceDiagram

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
Stop the capped error before the generic stream retry handler.
When Line 4434 throws, recursivelyMakeClineRequests catches it as a stream failure at Line 3271. With auto-approval enabled, that handler calls backoffAndAnnounce and pushes another retry at Lines 3298-3323. The task therefore continues making API requests after the cap.
Use a distinct terminal error or result for the retry limit. Handle it before the generic stream-failure retry path. Add a test that runs the task-loop path and verifies that it performs four requests and three backoffs only.

As per coding guidelines, “Prefer the narrowest test layer that proves behavior: ... integration tests for internal cross-module contracts.”

Bounded auto-approval retry loop in
attemptApiRequestCloses a class of unbounded retry:
attemptApiRequestrecurses under theautoApprovalEnabledpath with no cap — onlythis.abortstops it. On apersistent API error (e.g. HTTP 429 fair-usage, a whole-account rate limit),
each retry is not only a failure but worsens the condition, and the only bound
was
MAX_EXPONENTIAL_BACKOFF_SECONDSon the delay, not the count.Observed impact (both on a persisted 429, far from theoretical):
