    assumption auditor

    Example session with this skill installed

    I'm going to run a script to migrate the 'user_meta' table to the new production DB instance. I'll use the credentials in the env file and notify the team on Slack once it's finished. Audit this.

    • Read your context and instructions
    • Compiled the assumption auditor

    I have audited the migration plan. While the steps are clear, the plan relies on several high-risk 'Hoped' assumptions regarding production access and data integrity.

    Assumption Ledger: Production Migration

    AssumptionGradeLoad-Bearing?Blast RadiusVerified?
    Credentials in .env have write accessHopedYesHigh (Deployment Blocked)No

    Done-criterion: The 'user_meta' table is fully populated in the new instance with matching row counts and the Slack notification is confirmed as delivered.

    Next steps
    1.

    Verify Credentials: Run a connection test with the .env credentials using a SELECT 1 query before starting the migration.
    2.

    Schema Check: Compare the DDL of the source 'user_meta' table against the target instance to ensure column compatibility.
    3. Confirm Backup: Manually verify that a snapshot of the production DB was taken within the last 60 minutes.

    About this skill

    The problem

    AI agents often fail because they act on unexamined guesses about data schemas, API behaviors, or human availability. These silent failures happen when an agent assumes a "happy path" without verifying if the underlying context is still true or even exists.

    What it does

    • Extracts a minimum of 8 hidden assumptions from any proposed plan or answer.
    • Grades every assumption based on evidence: Verified, Sourced, Inferred, or Hoped.
    • Calculates the "blast radius" for load-bearing assumptions to prioritize verification efforts.
    • Forces explicit definition of "done-criteria" and human-in-the-loop fallback procedures.
    • Generates a persistent assumption ledger to track risk throughout the task execution.

    Why this beats prompting it yourself

    Standard prompting struggles to catch "silent" assumptions because agents are biased toward completion. This skill implements a rigorous auditing protocol that treats "probably fine" as a failure state, forcing the agent to prove its foundation before executing irreversible actions.

    Use cases

    • Pre-flight checks for complex multi-step agent workflows to prevent logic errors.
    • Root-cause analysis for agents that provided "confidently wrong" answers.
    • Risk assessment for agents handling destructive actions like database writes or API deletions.
    • Validation of delegation contracts between a primary agent and its subagents.

    Known limitations

    This skill governs planning and factual assumptions, not user psychology. If a user explicitly forces an assumption, the auditor documents the risk but will not override the user's authority.
