Fields

output: String

output_data: Option<Value>

Structured output when the tool declared one (ToolOutput::data). Feeds SOP step capture and data-flow surfaces; the LLM sees only output.

success: bool

error_reason: Option<String>

Raw failure text on the data path. Credential scrubbing is a rendering concern applied at each human-facing surface (observer events, post-execution log line, CLI progress), never stored pre-scrubbed here.

duration: Duration

receipt: Option<String>

Cryptographic HMAC receipt proving this tool actually executed. Present only when tool receipts are enabled in config.
