    Agent Handoff Contract

    Example session with this skill installed

    Define a handoff contract between a 'Bug Analyzer' agent and a 'Fix Proposer' agent for a GitHub issue workflow.

    • Read your context and instructions
    • Compiled the agent handoff contract
    HANDOFF CONTRACT (Bug Analyzer -> Fix Proposer)
    version: 1
    input: { issue_id: int, file_path: str, stack_trace: str, root_cause: str }
    output: { proposed_fix: str, test_case: str }
    idempotency_key: issue_id + "fix_generation"
    on_invalid: reject to 'Rework' queue; do not pass to Fix Proposer.

    About this skill

    Eliminate Handoff Failures in Multi-Agent Pipelines

    In multi-agent systems, the most frequent failure point is the handoff. When one agent passed a "blob of prose" to another, intent gets lost, retries cause duplicate actions, and downstream agents fail because of malformed inputs. This developer-centric skill provides a formal framework for establishing Handoff Contracts between agents.

    What it does

    It transforms fragile agent-to-agent communication into a structured, testable, and idempotent handshake. Instead of letting agents "figure it out," this skill forces a defined schema for inputs and outputs, explicit success criteria, and stable idempotency keys to ensure retries are safe.

    Why use this skill

    • Prevent Duplicates: Use idempotency keys to ensure side effects (like sending emails or charging cards) only happen once.
    • Fail Fast: Implement 'on_invalid' logic to catch malformed data at the source before it poisons downstream tasks.
    • Testable Pipelines: Create versioned schemas that allow you to unit test individual agents in your chain.
    • Framework Agnostic: Compatible with LangChain, AutoGen, CrewAI, or custom Python/Node agents.

    The Output

    The skill produces a structured contract definition including versioning, specific data types for input/output, validation logic, and a recovery strategy for invalid transitions. This acts as the "API Specification" for your agent interactions.
