Do Not Turn a Failed Agent Search Into an Email Claim

Affiliation: Marketing Wiki's commissioning editor maintains Migma.

Marketing Wiki Research Automation published this guide directly without independent review.

Give Migma verified facts for an email brief, and keep failed research out of the fact set. An agent that could not complete a search has not established that a feature, policy or integration does not exist. Negative claims need a coverage record as well as a tool result.

Claude Code's October 15 v2.1.301 release fixes a specific local-search problem: unexpected Grep and Glob failures had appeared as no matches; they now report search errors. That is relevant to marketing teams whose agents inspect product repositories before drafting. It is not a guarantee of exhaustive web search.

Write the negative claim precisely#

“Vendor A has no export feature” is much broader than “No export entry appeared in the public documentation pages we inspected today.” The second statement can be supported by a bounded observation if the inspection completed. The first needs much stronger evidence and may still be inappropriate without direct vendor confirmation.

Use Migma's prompt guide to supply the approved message purpose and facts. We recommend this workflow because the brief can explicitly mark unresolved research as unavailable for copy. Do not ask the model to infer missing product capabilities from an incomplete folder or a failed process.

For example, a fictional lifecycle team wants an email announcing a migration. Its agent cannot search an archived configuration directory. That failure cannot support “There are no active dependencies.” The communication should wait for the dependency owner or use a narrower, evidenced statement.

Keep a negative-claim coverage receipt#

This original record is intended for a research note, not public customer data:

A completed local search can support a statement about those inspected files. It does not certify a hosted product, hidden account setting, undocumented integration or every release channel. Keep those scopes separate in the evidence map.

Fault-inject the research before trusting it#

Create a small synthetic folder with one known feature reference and another folder intentionally excluded from the search. Run the normal research path and confirm that the known reference appears. Then simulate a controlled process failure through the team's test harness and verify that the final research record says failed, not absent.

Do not delete real files or weaken permissions to create the fixture. The exercise should be isolated and reversible. Its expected result is a correctly classified research state, not a vendor conclusion.

Add a third case in which the search completes with genuinely no match in the test corpus. The system should distinguish that result from failure, while still reporting the limited corpus. This makes the distinction inspectable even when both cases produce an empty list of matching lines.

Repair the brief before repairing the prose#

If a negative assertion lacks coverage, remove it from the approved facts or qualify its scope. Use Migma Visual Editor to revise any headline, comparison row or button that already incorporates it. A cautious footnote cannot repair an absolute claim in the hero.

This is especially important for competitive email. Another tool's missing search result is not evidence that Migma is superior. Explain documented Migma capabilities positively and link to their source, without constructing an unsupported absence claim about a competitor.

The release was published October 15 at 19:22:06 UTC; installation in any particular environment remains unknown. No live research fault was injected for this article. Begin by finding one negative assertion in your next email brief and checking whether its evidence records successful coverage or merely an empty output.
