preview_snippet
Preview (test-run) a Code Glue snippet — Test-run a snippet (by snippet_id, or raw code) against a real captured payload WITHOUT dispatching anything.
Test-run a snippet (by snippet_id, or raw code) against a real captured payload WITHOUT dispatching anything. Pass webhook_id+trigger to use the captured example payload, or provide an explicit payload. Returns the transformed payload, any PHP error and printed output. Always preview before assigning. Registered as the WordPress Ability flowsystems-webhook-actions/preview_snippet, so external AI tools (Claude Code, Cursor) can call it over MCP or REST with a scoped API token.
/ Plan step shape
{ "ability": "preview_snippet", "input": { "snippet_id": …, "code": …, "webhook_id": …, "trigger": …, "payload": …, "mode": … } }
/ Scope & confirmation
Minimum API-token scope for external (MCP/REST) callers: full. Runs without a confirmation pause (the overall plan is still user-approved before execution starts).
