## Evidence and limits

Ticker changes, exchange moves, de-SPAC closings, and split-related actions add context to issuer history. They do not by themselves establish dilution, current eligibility, or a causal explanation for a security's return. Preserve effective date and source reference alongside the related event or share-count analysis. See [API conventions](/api-conventions).

## Give this prompt to your agent

<Prompt>
  Use SEC API GET /v1/dilution/corporate-actions to find capital-structure context from ticker, exchange, de-SPAC, and split actions. For the standard response, preserve `data`, `hasMore`, `nextCursor`, `per-row: effectiveDate, actionType, oldSymbol, newSymbol, verification.confidence`, `requestId`. When requesting the compact agent view, keep its returned fields and requestId. Retain traceparent only from standard-response body or HTTP-header context when present; the compact agent view does not include it. Return a concise markdown summary and the structured fields needed for the next step without filling in missing disclosure data.
</Prompt>

## Failure posture

* keep action type, effective date, and source provenance
* use corporate actions as context rather than a dilution conclusion
* reconcile ticker changes before joining historical issuer records
