Supply the source channel/event, Legacy Harness arguments, approved cwd, and a concise summary. +- A local jobs_start returns after durable acceptance; a remote request returns after signed publication with requested state. Never wait on Legacy Harness in the foreground. Use jobs_status or jobs_logs only for local facts from a later turn. Cancellation requires an authenticated controller or an authorized signed public cancel event; this model profile cannot cancel jobs. +- Never attempt a shell, Buzz CLI command, process launch, executable path, foreground lh invocation, file or git mutation, lifecycle shutdown, environment injection, or stdin payload. This profile intentionally provides none of those capabilities. +"#; diff --git a/crates/buzz-dev-mcp/src/managed_jobs.rs b/crates/buzz-dev-mcp/src/managed_jobs.rs new file mode 100644 index 00000000000..632a5f8e1fc --- /dev/null +++ b/crates/buzz-dev-mcp/src/managed_jobs.rs @@ -0,0 +1,343 @@ +use crate::collaboration::CollaborationClient; +use buzz_runtime::{ + protocol::{ + MAX_ARGV_ELEMENTS, MAX_ARG_BYTES, MAX_CWD_BYTES, MAX_JOB_ARGV_JSON_BYTES, + MAX_LOG_TAIL_LINES, MAX_SUMMARY_BYTES, + }, + ClientError, JobId, JobStartRequest, JobState, RuntimeClient, +}; +use rmcp::ErrorData; +use schemars::JsonSchema; +use serde::Deserialize; +use uuid::Uuid; + +#[derive(Debug, Deserialize, JsonSchema)] +#[serde(deny_unknown_fields)] +pub(crate) struct JobsStartParams { + /// Channel UUID that owns the durable job. + pub channel_id: String, + /// Triggering Buzz event ID, when the job was requested from a message. + #[serde(default)] + pub source_event_id: Option, + /// Optional target managed agent.
