api rate limit hit mid proposal answer regeneration causing failed run: how to fix it

Bulk answer regeneration fires many API calls fast and hits the limit. Throttle calls to a safe rate, checkpoint each regenerated answer, and resume from the checkpoint after a limit hit.

When to use this skill

• Bulk answer regeneration fails partway
• API 429s appear in the agent log

When not to use this skill

• Regeneration completes but answers are worse (a quality issue)
• Regeneration never starts (a configuration issue)

Tool compatibility

Before you start

• Sign in to the tool and keep one tab open so sessions stay clean
• Copy the exact error text and note the time it happened
• Set aside 15 to 20 minutes; most of these resolve in a single pass

Quick diagnosis

Make sure this is the right skill before you invest the 15 minutes.

• If you are dealing with bulk answer regeneration fails partway, start at step 1 below.
• If instead regeneration completes but answers are worse (a quality issue), stop here; you need a different skill.
• If neither quite matches, compare your screen against the verbatim error block at the top; that block is exactly what this skill covers.

Fix it in steps

1. Throttle the call rate

Limit regeneration to a fixed number of calls per minute.

Expected: Expected: call rate stays under the documented limit.

2. Checkpoint each answer

Save every regenerated answer as it completes.

Expected: Expected: progress survives a crash.

3. Back off on 429

On a rate limit response, wait and retry with increasing delays.

Expected: Expected: run pauses instead of dying.

4. Resume from the checkpoint

Restart after the last saved answer.

Expected: Expected: run completes without redoing work.

Confirm each step worked

Run through this checklist before moving on. If a check fails, redo that step instead of pushing ahead.

• Step 1 (throttle the call rate): Expected: expected: call rate stays under the documented limit.
• Step 2 (checkpoint each answer): Expected: expected: progress survives a crash.
• Step 3 (back off on 429): Expected: expected: run pauses instead of dying.
• Step 4 (resume from the checkpoint): Expected: expected: run completes without redoing work.

Quick recap

1. Throttle the call rate
2. Checkpoint each answer
3. Back off on 429
4. Resume from the checkpoint

Still stuck?

Gather three things: the exact error text, the time it happened, and what changed just before it broke. Check the vendor status page for an active incident. Then open a support ticket with those three things; it cuts the back-and-forth in half. For agent runs, attach the last 50 lines of the agent log too, since the loop or timeout signature in the log usually names the cause.

Variant phrasings

agent rate limit answer regeneration

Throttle plus checkpoints fix it. If this matches what you saw, the steps above apply as written.

proposal answer regeneration 429

Backoff and resume. If this matches what you saw, the steps above apply as written.

Why it happens

Regeneration is bursty by nature: the agent fires one call per answer as fast as possible. Without throttling, the burst trips the limit, and without checkpoints the retry redoes everything.

Edge cases

• Read the API rate limit docs; the real limit is often lower than assumed
• Regenerate overnight or off peak when limits are effectively higher
• A run that 429s on the first call needs a lower rate, not more retries
