List Tools in a Tool Source

List the Tools discovered from one ToolSource as bounded summaries — name, description, schema hash, safety hints, transport binding, and enablement — through the standard data/next_page envelope. Complete input and output schemas require the targeted read.

Checkfu support posture: alpha; hosted. Required evidence journey: capability-catalog. Deployment-specific readiness and the latest proven release are available from GET /v1/support/capabilities.
