agent rate limited by Vanta mid evidence pull questionnaire packet incomplete at send

TL;DR

Fix this in the Vanta evidence pull by acting on the exact message first: pace the Vanta evidence calls with backoff, pull the packet in control batches with a checkpoint per batch, and hold the send until every batch confirms so an incomplete packet is never sent. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

Use this when

• The operation in the Vanta evidence pull fails with this exact message: agent rate limited by Vanta mid evidence pull questionnaire packet incomplete at send.
• The same failure repeats on retry with unchanged inputs.
• A review, export or check is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in the Vanta evidence pull, and copy the full message plus the questionnaire, answer or evidence item involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: pace the Vanta evidence calls with backoff, pull the packet in control batches with a checkpoint per batch, and hold the send until every batch confirms so an incomplete packet is never sent. Verify: the packet is complete with evidence for every control before it is sent.
3. Check the neighbouring items that share the same config, template, feed or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Compare the result counts, decisions or alerts against the source in the Vanta evidence pull so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation in the Vanta evidence pull on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

evidence pulls burst against the Vanta limit and the packet was assembled from whatever arrived before throttling, leaving it incomplete at send time.
