## TL;DR
Fix this in the agent workflow for SOC alert enrichment by acting on the exact message first: run a preflight check before the agent starts to attach threat intel to a SOC incident (source reachable, inputs present, output location writable), then run with per-item error capture so one bad item is logged and skipped instead of ending the job. 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.

```text
agent failed to complete attach threat intel to a SOC incident
```

## Use this when
- The operation in the agent workflow for SOC alert enrichment fails with this exact message: agent failed to complete attach threat intel to a SOC incident.
- 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 agent workflow for SOC alert enrichment, and copy the full message plus the alert, incident or enrichment record 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: run a preflight check before the agent starts to attach threat intel to a SOC incident (source reachable, inputs present, output location writable), then run with per-item error capture so one bad item is logged and skipped instead of ending the job. Verify: the preflight passes, the rerun completes, and any skipped item is named in the run log with its reason.
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 agent workflow for SOC alert enrichment 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 agent workflow for SOC alert enrichment 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
the job had no preflight and no per-item isolation, so the first missing input or bad record failed the entire run instead of one item.

## Variant phrasings

### agent failed to complete attach threat intel to a SOC incident
The verbatim form searchers paste from the terminal or console. Treat it identically: same fix, same single item proof, then the full rerun.

### How to fix: agent failed to complete attach threat intel to a SOC incident error failure
The how-to phrasing for the same failure in the agent workflow for SOC alert enrichment. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

### the agent workflow for SOC alert enrichment troubleshooting for this failure
The symptom-first phrasing used when the console hides the full message. Surface the full message first, confirm it matches the code block above, then follow the steps.

Compatibility: the agent workflow for SOC alert enrichment at current versions, plus the platform API or console the query names; no extra tooling beyond a text editor and the source system access needed to verify counts.
