    Example session with this skill installed

    Case: A transactional producer is fenced after a broker rolling upgrade.

    Provided: Kafka transaction coordinator state and producer epoch logs (illustrative, partial). Potential exception: coordinator epoch rollback rejects a valid producer generation. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

    Repair Apache Kafka Transaction Coordinator Epoch Regression — SYNTHETIC EVIDENCE-LIMITED REVIEW

    Case received

    A transactional producer is fenced after a broker rolling upgrade.

    Evidence register

    • S1: Kafka transaction coordinator state and producer epoch logs — PARTIAL / UNVERIFIED.
    • S2: approved operating baseline / documented policy — NOT PROVIDED; REQUIRED TO VERIFY.
    • S3: timestamped revision or change record — NOT PROVIDED; REQUIRED TO VERIFY.
    • S4: accountable reviewer and approval evidence — NOT PROVIDED; REQUIRED TO VERIFY.

    Investigation checks

    1. Establish the identity, timestamp basis and revision lineage of Kafka transaction coordinator state and producer epoch logs; document missing or contradictory records. — PENDING CORROBORATION.
    2. Reconstruct the event sequence surrounding coordinator epoch rollback rejects a valid producer generation, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
    3. Compare the evidence with the approved baseline; test the competing explanations for: A transactional producer is fenced after a broker rolling upgrade. — PENDING CORROBORATION.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for bounded transactional fencing recovery test matrix. — PENDING CORROBORATION.

    Deliverables

    • time-aligned evidence index for Kafka transaction coordinator state and producer epoch logs: DRAFT / INCOMPLETE until inputs are validated.
    • exceptions and alternative hypotheses for coordinator epoch rollback rejects a valid producer generation: DRAFT / INCOMPLETE until inputs are validated.
    • approval-gated bounded transactional fencing recovery test matrix and verification criteria: DRAFT / INCOMPLETE until inputs are validated.

    What this skill checks

    1. Establish the identity, timestamp basis and revision lineage of Kafka transaction coordinator state and producer epoch logs; document missing or contradictory records.
    2. Reconstruct the event sequence surrounding coordinator epoch rollback rejects a valid producer generation, citing exact record identifiers and independent checks.

    What to provide

    • Kafka transaction coordinator state and producer epoch logs
    • approved operating baseline / documented policy
    • timestamped revision or change record
    • accountable reviewer and approval evidence

    Deliverables

    • time-aligned evidence index for Kafka transaction coordinator state and producer epoch logs.
    • exceptions and alternative hypotheses for coordinator epoch rollback rejects a valid producer generation.
    • approval-gated bounded transactional fencing recovery test matrix and verification criteria.

    Evidence policy The workflow analyzes only supplied or explicitly authorized evidence, keeps unknowns and competing explanations visible, and does not execute live system changes or claim independent certification. An authorized owner must approve operational decisions.

    Requires manual provision of Kafka state logs and producer telemetry. Does not perform live system modifications or automated remediation.

    Frequently Asked Questions

    This skill analyzes transaction coordinator logs and producer telemetry to identify why producers are being 'fenced' or rejected, specifically following broker upgrades or leader migrations.

    The skill is compatible with any LLM-based agent capable of processing structured log files and text-based telemetry from Apache Kafka environments.

    No, this skill is strictly a diagnostic and planning tool; it analyzes provided data and generates recovery matrices without making direct API calls or configuration changes to your brokers.

    You will receive the structured diagnostic logic, a framework for evidence mapping, and a template for generating non-executing recovery test matrices.

    This skill is optimized for Apache Kafka versions that support idempotent and transactional producers (v0.11+), with specific logic for handling epoch management introduced in later versions.

    Connect your AI agent to Agensi through MCP, then ask it to use Repair Apache Kafka Transaction Coordinator Epoch Regression on your task. Your agent loads the latest approved version each time.
