    Example session with this skill installed

    Case: A durable consumer replays acknowledged messages only after changing deliver policy.

    Provided: consumer config diff and stream ACK telemetry (illustrative, partial). Potential exception: replayed sequence numbers across durable restart. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

    Repair NATS JetStream Consumer Deliver Policy Regression — SYNTHETIC EVIDENCE-LIMITED REVIEW

    Case received

    A durable consumer replays acknowledged messages only after changing deliver policy.

    Evidence register

    • S1: consumer config diff and stream ACK telemetry — 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 consumer config diff and stream ACK telemetry; document missing or contradictory records. — PENDING CORROBORATION.
    2. Reconstruct the event sequence surrounding replayed sequence numbers across durable restart, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
    3. Compare the evidence with the approved baseline; test the competing explanations for: A durable consumer replays acknowledged messages only after changing deliver policy. — PENDING CORROBORATION.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for consumer recovery acceptance checklist. — PENDING CORROBORATION.

    Deliverables

    • time-aligned evidence index for consumer config diff and stream ACK telemetry: DRAFT / INCOMPLETE until inputs are validated.
    • exceptions and alternative hypotheses for replayed sequence numbers across durable restart: DRAFT / INCOMPLETE until inputs are validated.
    • approval-gated consumer recovery acceptance checklist and verification criteria: DRAFT / INCOMPLETE until inputs are validated.

    Decision gate

    INCOMPLETE — HUMAN REVIEW REQUIRED. Sources, scope, time basis and sign-off remain unverified. No live change or approval has occurred.

    About this skill

    Repair NATS JetStream Consumer Deliver Policy Regression is a ToolForge Labs Cursor Skill evidence-review workflow. Trace consumer replay divergence after deployment.

    What this skill checks

    1. Establish the identity, timestamp basis and revision lineage of consumer config diff and stream ACK telemetry; document missing or contradictory records.
    2. Reconstruct the event sequence surrounding replayed sequence numbers across durable restart, citing exact record identifiers and independent checks.
    3. Compare the evidence with the approved baseline; test the competing explanations for: A durable consumer replays acknowledged messages only after changing deliver policy.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for consumer recovery acceptance checklist.

    What to provide

    • consumer config diff and stream ACK telemetry
    • approved operating baseline / documented policy
    • timestamped revision or change record
    • accountable reviewer and approval evidence

    Deliverables

    • time-aligned evidence index for consumer config diff and stream ACK telemetry.
    • exceptions and alternative hypotheses for replayed sequence numbers across durable restart.
    • approval-gated consumer recovery acceptance checklist 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.

    Find more skills like this on the Claude Skills Marketplace, the Codex Skills Marketplace and the Gemini Skills Marketplace, or browse Claude Skills for APIs & Backend.

    No live validation or direct platform access is asserted. Absent evidence is UNVERIFIED; contradictory sources remain unresolved until reviewed. Only authorized owners may approve real-world actions.

    Frequently Asked Questions

    This skill analyzes configuration diffs and telemetry logs to pinpoint exactly why a durable consumer is replaying messages, distinguishing between policy-driven behavior and state divergence.

    The skill requires consumer configuration JSON, stream telemetry logs, and relevant change records to perform its sequence reconstruction and lineage mapping.

    No, this is a diagnostic and advisory tool that provides an evidence-based recovery checklist; it does not execute live commands or directly modify your NATS cluster for safety reasons.

    This skill is optimized for LLMs capable of complex logical reasoning and large context windows, as it must process and compare multi-point telemetry data and configuration files.

    You receive the specialized diagnostic framework, the sequence reconstruction logic, and the templates for generating human-in-the-loop recovery checklists.

    Unlike generic troubleshooting prompts, this skill uses a specialized methodology specifically for NATS sequence tracking, ensuring that observations are verified against established JetStream baselines before suggesting a fix.
