session:join

What problem does it solve?

Joining and participating in coordinated multi-agent harness sessions can be confusing without clear role semantics, session discovery, and standardized CLI steps; this Skill codifies the join workflow so agents can reliably register, claim work, observe, and report progress without touching orchestration files directly.

Core Features & Use Cases

• Session discovery and picker: List active sessions, prompt the user when needed, and prefer the most recently created session for selection.
• Role-aware join flow: Join as worker, observer, reviewer, or improver and follow role-specific workflows for claiming tasks, running observations, or performing reviews.
• Operational guardrails: Enforce use of harness session commands, require --actor for mutating operations, and document task checkpointing, assignment, and completion patterns.
• Use Case: A developer agent joins a test coordination session, claims tasks, runs checks and tests, records checkpoints, and marks tasks done while observers monitor and create triage tasks from findings.

Quick Start

Use the session:join skill to join a session as a worker, let the runtime auto-detect, and follow the CLI output to obtain your agent ID for --actor.
