agent rate limit hit mid rfp amendment diff and failed to finish: how to fix it

Amendment diffs hammer the model with long document pairs and hit rate limits mid-run. Add exponential backoff with jitter, checkpoint each compared section, and resume from the last checkpoint instead of restarting.

When to use this skill

• Agent fails partway through an amendment diff
• Rate limit errors appear in the agent log mid-diff

When not to use this skill

• Diff completes but misses changes (an accuracy issue)
• Diff never starts (a startup failure)

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 agent fails partway through an amendment diff, start at step 1 below.
• If instead diff completes but misses changes (an accuracy 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. Add exponential backoff with jitter

Wrap the diff calls in retries that wait 2, 4, 8 seconds with random jitter.

Expected: Expected: transient 429s retry instead of killing the run.

2. Checkpoint each compared section

Save the diff result for each section as it completes.

Expected: Expected: progress survives a crash.

3. Resume from the last checkpoint

On restart, skip sections with saved diffs.

Expected: Expected: run continues where it stopped.

4. Batch smaller section pairs

Compare two or three sections per model call instead of the whole amendment.

Expected: Expected: fewer calls per minute, fewer 429s.

Confirm each step worked

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

• Step 1 (add exponential backoff with jitter): Expected: expected: transient 429s retry instead of killing the run.
• Step 2 (checkpoint each compared section): Expected: expected: progress survives a crash.
• Step 3 (resume from the last checkpoint): Expected: expected: run continues where it stopped.
• Step 4 (batch smaller section pairs): Expected: expected: fewer calls per minute, fewer 429s.

Quick recap

1. Add exponential backoff with jitter
2. Checkpoint each compared section
3. Resume from the last checkpoint
4. Batch smaller section pairs

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 amendment diff

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

rfp amendment diff agent 429

Smaller batches lower the rate. If this matches what you saw, the steps above apply as written.

Why it happens

Long amendment documents mean many large model calls in a burst, which trips per-minute limits. Without checkpoints, one 429 near the end discards all completed work and the retry starts over.

Edge cases

• Cap concurrent diff calls; sequential is slower but survives limits
• Log the section id with each checkpoint so resumes never duplicate work
• A diff that 429s three times on the same section needs a longer base delay, not more retries
