    Example session with this skill installed

    Case: Change data capture stream unexpectedly stops returning new rows.

    Provided: Snowflake stream offsets and ALTER TABLE SWAP event history (illustrative, partial). Potential exception: stream binding references retired table object identity after swap. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

    Repair Snowflake Stream Staleness After Schema Swap — SYNTHETIC EVIDENCE-LIMITED REVIEW

    Case received

    Change data capture stream unexpectedly stops returning new rows.

    Evidence register

    • S1: Snowflake stream offsets and ALTER TABLE SWAP event history — 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 Snowflake stream offsets and ALTER TABLE SWAP event history; document missing or contradictory records. — PENDING CORROBORATION.
    2. Reconstruct the event sequence surrounding stream binding references retired table object identity after swap, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
    3. Compare the evidence with the approved baseline; test the competing explanations for: Change data capture stream unexpectedly stops returning new rows. — PENDING CORROBORATION.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for stream continuity fixture and data engineering replay approval. — PENDING CORROBORATION.

    Deliverables

    • time-aligned evidence index for Snowflake stream offsets and ALTER TABLE SWAP event history: DRAFT / INCOMPLETE until inputs are validated.
    • exceptions and alternative hypotheses for stream binding references retired table object identity after swap: DRAFT / INCOMPLETE until inputs are validated.
    • approval-gated stream continuity fixture and data engineering replay approval and verification criteria: DRAFT / INCOMPLETE until inputs are validated.

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

    About this skill

    Repair Snowflake Stream Staleness After Schema Swap is a ToolForge Labs Cursor Skill evidence-review workflow. Trace stream consumption failures after table swap migration.

    What this skill checks

    1. Establish the identity, timestamp basis and revision lineage of Snowflake stream offsets and ALTER TABLE SWAP event history; document missing or contradictory records.
    2. Reconstruct the event sequence surrounding stream binding references retired table object identity after swap, citing exact record identifiers and independent checks.
    3. Compare the evidence with the approved baseline; test the competing explanations for: Change data capture stream unexpectedly stops returning new rows.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for stream continuity fixture and data engineering replay approval.

    What to provide

    • Snowflake stream offsets and ALTER TABLE SWAP event history
    • approved operating baseline / documented policy
    • timestamped revision or change record
    • accountable reviewer and approval evidence

    Deliverables

    • time-aligned evidence index for Snowflake stream offsets and ALTER TABLE SWAP event history.
    • exceptions and alternative hypotheses for stream binding references retired table object identity after swap.
    • approval-gated stream continuity fixture and data engineering replay approval 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.

    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 automates the investigation of "broken" streams that occur when a table swap causes a stream to point to a retired object ID, helping you identify exactly where and why data capture stopped.

    The skill requires metadata exports from your Snowflake environment, specifically stream offset details, ALTER TABLE event history, and table ID telemetry.

    No, this skill is designed for audit and planning; it generates a validated replay strategy and evidence report without directly executing DDL or DML commands on your live production data.

    It is ideal for data engineers using Blue-Green deployment patterns or those performing schema migrations who notice downstream consumers are missing data despite the stream appearing 'active.'

    You receive the specialized diagnostic framework, a structured evidence-labeling system, and a guided workflow for generating data replay sequences for your engineering team.

    This skill is compatible with any AI agent that supports text-based reasoning and file uploads, allowing you to feed in your SQL query results for analysis.
