    Example session with this skill installed

    Case: A reproducible image build rejects a previously permitted plugin binary.

    Provided: Packer lockfile and plugin artifact checksum trail (illustrative, partial). Potential exception: declared plugin source digest differs from pinned download. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

    Repair Packer Plugin Checksum Lockfile Mismatch — SYNTHETIC EVIDENCE-LIMITED REVIEW

    Case received

    A reproducible image build rejects a previously permitted plugin binary.

    Evidence register

    • S1: Packer lockfile and plugin artifact checksum trail — 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 Packer lockfile and plugin artifact checksum trail; document missing or contradictory records. — PENDING CORROBORATION.
    2. Reconstruct the event sequence surrounding declared plugin source digest differs from pinned download, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
    3. Compare the evidence with the approved baseline; test the competing explanations for: A reproducible image build rejects a previously permitted plugin binary. — PENDING CORROBORATION.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for reproducible plugin provenance verification plan. — PENDING CORROBORATION.

    Deliverables

    • time-aligned evidence index for Packer lockfile and plugin artifact checksum trail: DRAFT / INCOMPLETE until inputs are validated.
    • exceptions and alternative hypotheses for declared plugin source digest differs from pinned download: DRAFT / INCOMPLETE until inputs are validated.
    • approval-gated reproducible plugin provenance verification plan 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 Packer Plugin Checksum Lockfile Mismatch is a ToolForge Labs ChatGPT Skill evidence-review workflow. Trace build failures after HashiCorp Packer plugin source migration.

    What this skill checks

    1. Establish the identity, timestamp basis and revision lineage of Packer lockfile and plugin artifact checksum trail; document missing or contradictory records.
    2. Reconstruct the event sequence surrounding declared plugin source digest differs from pinned download, citing exact record identifiers and independent checks.
    3. Compare the evidence with the approved baseline; test the competing explanations for: A reproducible image build rejects a previously permitted plugin binary.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for reproducible plugin provenance verification plan.

    What to provide

    • Packer lockfile and plugin artifact checksum trail
    • approved operating baseline / documented policy
    • timestamped revision or change record
    • accountable reviewer and approval evidence

    Deliverables

    • time-aligned evidence index for Packer lockfile and plugin artifact checksum trail.
    • exceptions and alternative hypotheses for declared plugin source digest differs from pinned download.
    • approval-gated reproducible plugin provenance verification plan 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 DevOps & Cloud.

    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 provides a structured auditing framework to determine if a checksum failure is due to a routine plugin registry migration or a legitimate security risk, saving hours of manual investigation.

    The skill supports all standard HashiCorp Packer environments that utilize `.packer.lock.hcl` files, including custom plugin mirrors and private registries.

    No, this skill operates as a non-executable investigation layer; it analyzes your provided logs and lockfiles to generate a verification report without making any changes to your production code or CI/CD pipelines.

    You receive the full investigation logic, the evidence-based auditing framework, and a structured template for generating verification reports ready for security review.

    You will need to provide the affected `.packer.lock.hcl` file, the specific error logs from your build failure, and any internal documentation regarding approved plugin sources.

    Unlike generic AI prompts, this skill enforces a strict evidence-based labeling system (VERIFIED vs. CONTRADICTED) to ensure audit-grade accuracy and prevent the AI from 'hallucinating' security resolutions.
