ariffazil Agent-to-Agent (A2A) Task Delegator Skill (a2a-task-delegator)
Establishes standardized task delegation RPC schemas, precondition locks, and output attestation contracts for multi-agent swarms (Claude Code, Antigravity, OpenCode, Kimi, Codex).

Best Practices for Federation Agents
- State Locking: Acquire state lock before starting a task to prevent race conditions across parallel agent runs.
- Attestation Receipt: Output completed task receipt with execution hash and status (
SEAL,HOLD,FAIL).
