    Repair Tekton Chains Attestation Predicate Drift

    Example session with this skill installed

    Case: A signed build attestation uses a stale predicate schema after the pipeline promotion.

    Provided: Tekton Chains signatures and provenance records (illustrative, partial). Potential exception: predicate schema mismatch across provenance signers. Request an evidence-limited review, identify missing sources and required sign-off; do not perform a live system change.

    Repair Tekton Chains Attestation Predicate Drift — SYNTHETIC EVIDENCE-LIMITED REVIEW

    Case received

    A signed build attestation uses a stale predicate schema after the pipeline promotion.

    Evidence register

    • S1: Tekton Chains signatures and provenance records — PARTIAL / UNVERIFIED.
    • S2: authorized baseline or procedure — NOT PROVIDED; REQUIRED TO VERIFY.
    • S3: timestamped event and change context — NOT PROVIDED; REQUIRED TO VERIFY.
    • S4: responsible reviewer / approval record — NOT PROVIDED; REQUIRED TO VERIFY.

    Four checks

    1. Normalize identifiers and timestamps in Tekton Chains signatures and provenance records; preserve original document revisions. — PENDING CORROBORATION.
    2. Locate predicate schema mismatch across provenance signers and link every finding to exact source rows or event IDs. — PENDING CORROBORATION.
    3. Test whether the stated scenario is supported by the baseline, sequence constraints and independent counter-evidence. — PENDING CORROBORATION.
    4. Define an owner-reviewed, reversible verification sequence for reviewed attestation verification plan before any field or production change. — PENDING CORROBORATION.

    Deliverables

    • Tekton Chains signatures and provenance records traceability crosswalk: DRAFT / INCOMPLETE until inputs are validated.
    • predicate schema mismatch across provenance signers exception ledger: DRAFT / INCOMPLETE until inputs are validated.
    • reviewed attestation verification plan approval and validation plan: DRAFT / INCOMPLETE until inputs are validated.

    Decision gate

    INCOMPLETE — HUMAN REVIEW REQUIRED. Source chronology, approvals, scope and independent evidence have not been verified. No execution or live certification claimed.

    About this skill

    Repair Tekton Chains Attestation Predicate Drift is a ToolForge Labs Cursor Skill workflow. Diagnose mismatched Tekton signed provenance predicates after pipeline upgrades.

    What this skill checks

    1. Normalize identifiers and timestamps in Tekton Chains signatures and provenance records; preserve original document revisions.
    2. Locate predicate schema mismatch across provenance signers and link every finding to exact source rows or event IDs.
    3. Test whether the stated scenario is supported by the baseline, sequence constraints and independent counter-evidence.
    4. Define an owner-reviewed, reversible verification sequence for reviewed attestation verification plan before any field or production change.

    What to provide

    • Tekton Chains signatures and provenance records
    • authorized baseline or procedure
    • timestamped event and change context
    • responsible reviewer / approval record

    Deliverables

    • Tekton Chains signatures and provenance records traceability crosswalk.
    • predicate schema mismatch across provenance signers exception ledger.
    • reviewed attestation verification plan approval and validation plan.

    Evidence policy The workflow uses only supplied, authorized evidence, separates source facts from inference and missing data, and does not claim live tests or certify external decisions. Owner approval is required for operational changes.

    Frequently Asked Questions

    This skill automates the diagnosis of SLSA provenance failures that occur when Tekton Chains upgrades change the JSON structure of your attestations, ensuring your CI/CD pipeline remains compliant without manual debugging.

    It is compatible with standard Tekton Chains signatures and in-toto provenance predicates (v0.1 and v1.0), and it integrates with any AI agent capable of processing structured JSON build records.

    No, this skill is designed for security and isolation; it requires you to provide the signature and provenance JSON files directly, ensuring it never needs direct access to your production Kubernetes clusters.

    You receive the specialized evidence analysis logic, the traceability crosswalk module for identifying drift, and a template for generating reversible verification plans for your security team.

    The skill generates an exception ledger that tags every mismatch with specific status labels (VERIFIED, CONTRADICTED, etc.), providing a clear audit trail that can be used for compliance reporting or manual remediation.
