A conversation message, discriminated on role. This is pi’s AgentMessage union plus the RPC-only bashExecution role.

Variants

User

Fields

content: Value

A plain string or an array of content blocks — both are legal.

timestamp: f64

attachments: Vec<Value>

extra: Map<String, Value>

Assistant

Fields

content: Vec<ContentBlock>

api: String

provider: String

model: String

usage: Option<Usage>

stop_reason: String

stop, length, toolUse, error, aborted, or (harness-v2) deferred. Left open for forward compat.

timestamp: f64

extra: Map<String, Value>

ToolResult

Fields

tool_call_id: String

tool_name: String

content: Value

usage: Option<Usage>

Nested LLM work performed by the tool; contributes to session totals when present.

is_error: bool

timestamp: f64

extra: Map<String, Value>

BashExecution

Created by the RPC bash command, never by LLM tool calls. On the next prompt it is rewritten into a user message for the model.

Fields

command: String

output: String

exit_code: Option<i64>

cancelled: bool

truncated: bool

full_output_path: Option<String>

timestamp: f64

extra: Map<String, Value>
