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.

Doesn't this throw land in the streaming_failed catch in recursivelyMakeClineRequests (line 3271), which re-pushes the stack item with retryAttempt + 1 and continues (3316-3323)? Line 2798 reads retryAttempt back off the stack item, so the next generator call starts from 0 — production still loops without bound after these four attempts. Would the cap need to live at the consumer re-push (or a shared counter) to actually bound the loop?

This drives attemptApiRequest directly, but production consumes it through recursivelyMakeClineRequests, whose catch re-pushes with a fresh retryAttempt. Could we assert the cap through that boundary too, so a consumer-side regression can't ship green?

On the consumer side, the streaming_failed handler also calls backoffAndAnnounce (Task.ts:3301) before re-pushing, so the final refused request sleeps on the full backoff before being re-queued. Is that the intended ordering?

When MAX_CONTEXT_WINDOW_RETRIES is exhausted, the truncation branch above falls through to this check with retryAttempt already >= 3 — the message blames the auto-approval cap for an exhaustion failure. Worth a distinct message for that case?

Does the bound hold for mid-stream failures? A stream that yields a first chunk and then errors exits through the consumer loop without reaching this check, so the comment may overclaim.

…temptApiRequest
The internal cap did not bound production: the streaming_failed handler in
recursivelyMakeClineRequests caught the capped error and re-pushed the stack
item, and since attemptApiRequest only checks the cap after an error occurs,
every re-push issued another full API request — the loop never ended.
- ApiRetryCapExceededError (exported): distinct terminal signal from the
first-chunk cap; the consumer honors it before the generic retry path —
loud say("error"), abortReason=streaming_failed, abortTask, re-throw into
the outer catch so the parent sees didEndLoop=true (a bare break reported
"completed normally").
- Consumer-side cap for mid-stream failures: retryAttempt at
MAX_AUTO_APPROVAL_RETRIES with auto-approval on stops instead of
re-pushing.
- Context-window exhaustion falling through the cap now names its own cause
instead of blaming the auto-approval cap.
- Constant comment scoped to what it actually bounds (first-chunk +
mid-stream re-push; not mid-stream without auto-approval).
- Tests: cap asserted through the recursivelyMakeClineRequests boundary
(4 requests / 3 backoffs, mutation-hardened), marker terminal (1 attempt /
0 backoffs), context-window message, instanceof on the existing test.
Mutation-verified: disabling the consumer guard reddens both consumer
tests; disabling the context-window cause reddens the message test.

All five points from the 08-29 review are addressed — you were right that the cap as written did not bound production. New commits rework the fix so the loop is bounded at the consumer boundary. 1. The re-push loop is now terminal at the consumer (

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Assert the terminal outcome in the stateForBackoff undefined test.
The second createMessage call throws ApiRetryCapExceededError mid-stream, so the terminal handler in Task.ts runs: it calls say("error", capMessage), sets abortReason = "streaming_failed", and calls abortTask(). The test registers spies for say (Line 1468) and abortTask (Line 1469) but asserts neither. The say spy is currently dead code.
expect(attempts).toBe(2) proves the re-push stopped, but it does not prove the stop was the terminal cap path. A regression that ends the loop for another reason (for example, the outer catch swallowing an error before the terminal handler) still satisfies the count and result === true.
Bind the spies to assertions so the terminal contract is covered.
As per path instructions, "For tests that assert only mock call counts, confirm a corresponding return-value assertion exists" and "Require regression coverage at the lowest valid harness with behavior-focused assertions, including relevant negative, error, false/unset, and boundary cases."
