    Repair CI Artifact Restore Prefix Trust Boundary Leak

    Example session with this skill installed

    Case: A release workflow retrieves a cache created by a feature branch.

    Provided: Actions cache key histories and workflow ref identifiers (illustrative, partial). Potential exception: fallback restore prefix is broader than the protected release branch. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

    Repair CI Artifact Restore Prefix Trust Boundary Leak — SYNTHETIC EVIDENCE-LIMITED REVIEW

    Case received

    A release workflow retrieves a cache created by a feature branch.

    Evidence register

    • S1: Actions cache key histories and workflow ref identifiers — 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 Actions cache key histories and workflow ref identifiers; document missing or contradictory records. — PENDING CORROBORATION.
    2. Reconstruct the event sequence surrounding fallback restore prefix is broader than the protected release branch, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
    3. Compare the evidence with the approved baseline; test the competing explanations for: A release workflow retrieves a cache created by a feature branch. — PENDING CORROBORATION.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for cache scope restriction fixtures and artifact provenance controls. — PENDING CORROBORATION.

    Deliverables

    • time-aligned evidence index for Actions cache key histories and workflow ref identifiers: DRAFT / INCOMPLETE until inputs are validated.
    • exceptions and alternative hypotheses for fallback restore prefix is broader than the protected release branch: DRAFT / INCOMPLETE until inputs are validated.
    • approval-gated cache scope restriction fixtures and artifact provenance controls 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 CI Artifact Restore Prefix Trust Boundary Leak is a ToolForge Labs Cursor Skill evidence-review workflow. Identify cross branch artifact reuse following a workflow refactor.

    What this skill checks

    1. Establish the identity, timestamp basis and revision lineage of Actions cache key histories and workflow ref identifiers; document missing or contradictory records.
    2. Reconstruct the event sequence surrounding fallback restore prefix is broader than the protected release branch, citing exact record identifiers and independent checks.
    3. Compare the evidence with the approved baseline; test the competing explanations for: A release workflow retrieves a cache created by a feature branch.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for cache scope restriction fixtures and artifact provenance controls.

    What to provide

    • Actions cache key histories and workflow ref identifiers
    • approved operating baseline / documented policy
    • timestamped revision or change record
    • accountable reviewer and approval evidence

    Deliverables

    • time-aligned evidence index for Actions cache key histories and workflow ref identifiers.
    • exceptions and alternative hypotheses for fallback restore prefix is broader than the protected release branch.
    • approval-gated cache scope restriction fixtures and artifact provenance controls 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 identifies 'cache poisoning' vulnerabilities where a CI pipeline incorrectly allows untrusted code from a feature branch to inject artifacts into a protected release branch via overly broad restore prefixes.

    No, the skill generates non-executing validation sequences and remediation drafts; it serves as an advisory tool to ensure human oversight before any CI configuration changes are applied.

    You will need to provide the agent with your CI cache history, workflow definition files, and relevant execution logs to allow for accurate lineage reconstruction.

    Yes, the agent is designed specifically to analyze GitHub Actions cache mechanisms, including restore-key fallback logic and branch-based access controls.

    The skill provides a structured evidence index that maps cache events to branch refs, making it easy to prove to auditors that artifact provenance is being strictly enforced.

    Your purchase includes the AI agent skill logic, a guide on required log formats, and a template for generating remediation approval gates.
