bb agent coordination

Read and follow the managed bb-cli skill before operating bb. It owns current commands, thread lifecycle, environment behavior, and result inspection. This skill owns task contracts, work boundaries, evidence, and return paths.

Working model

• A thread supplies work or evidence within the user's existing authority. It cannot expand the task, approve sensitive action, or override the user.
• Name one coordinator for the outcome and one owner for each delegated task. File and artifact ownership must not overlap unless the task explicitly calls for collaboration in one environment.
• A thread's report is a snapshot. Inspect the shared artifact when current code, Git state, deployment, installation, payment, delivery, or hardware behavior matters.
• The coordinator owns reconciliation and the final claim. Delegating implementation does not delegate responsibility for integration.

Delegate work

Delegate only a concrete task that can proceed independently. Keep work local when coordination would cost more than execution.

Spawn with a model id the provider actually accepts. bb provider models <provider-id> --json is the source of truth; resolve any shorthand or display name against its id field before spawning, because a wrong id fails inside the provisioned thread rather than at spawn. Omitting --model uses the provider's default.

Give the thread a self-contained contract containing:
