    Repair GitHub Codespaces Prebuild Feature Version Drift

    Example session with this skill installed

    Case: New codespace boots with older development tools than declared configuration.

    Provided: devcontainer feature lock metadata and Codespaces prebuild activity logs (illustrative, partial). Potential exception: prebuild cache uses a prior feature digest after repository ref update. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

    Repair GitHub Codespaces Prebuild Feature Version Drift — SYNTHETIC EVIDENCE-LIMITED REVIEW

    Case received

    New codespace boots with older development tools than declared configuration.

    Evidence register

    • S1: devcontainer feature lock metadata and Codespaces prebuild activity logs — 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 devcontainer feature lock metadata and Codespaces prebuild activity logs; document missing or contradictory records. — PENDING CORROBORATION.
    2. Reconstruct the event sequence surrounding prebuild cache uses a prior feature digest after repository ref update, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
    3. Compare the evidence with the approved baseline; test the competing explanations for: New codespace boots with older development tools than declared configuration. — PENDING CORROBORATION.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for developer platform owner environment parity fixture and prebuild invalidation. — PENDING CORROBORATION.

    Deliverables

    • time-aligned evidence index for devcontainer feature lock metadata and Codespaces prebuild activity logs: DRAFT / INCOMPLETE until inputs are validated.
    • exceptions and alternative hypotheses for prebuild cache uses a prior feature digest after repository ref update: DRAFT / INCOMPLETE until inputs are validated.
    • approval-gated developer platform owner environment parity fixture and prebuild invalidation 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 GitHub Codespaces Prebuild Feature Version Drift is a ToolForge Labs ChatGPT Skill evidence-review workflow. Trace reproducibility failures between Codespaces prebuild and runtime.

    What this skill checks

    1. Establish the identity, timestamp basis and revision lineage of devcontainer feature lock metadata and Codespaces prebuild activity logs; document missing or contradictory records.
    2. Reconstruct the event sequence surrounding prebuild cache uses a prior feature digest after repository ref update, citing exact record identifiers and independent checks.

    What to provide

    • devcontainer feature lock metadata and Codespaces prebuild activity logs
    • approved operating baseline / documented policy
    • timestamped revision or change record
    • accountable reviewer and approval evidence

    Deliverables

    • time-aligned evidence index for devcontainer feature lock metadata and Codespaces prebuild activity logs.
    • exceptions and alternative hypotheses for prebuild cache uses a prior feature digest after repository ref update.
    • approval-gated developer platform owner environment parity fixture and prebuild invalidation 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 Agents & Orchestration.

    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 the specific gap between your current devcontainer feature definitions and the stale cached versions being used by GitHub's prebuild runners, preventing environment inconsistency across your team.

    It is optimized for use with advanced LLMs (like GPT-4 or Claude 3.5) that support long-context reasoning for log analysis and is compatible with any AI agent platform that allows document uploads.

    You will receive the specialized agent framework, a structured evidence-labeling schema, and a step-by-step investigation protocol designed to process devcontainer metadata and prebuild logs.

    No, this skill operates as a diagnostic advisor; it analyzes your logs and metadata to provide a verification plan, but it does not require or request write-access to your GitHub repositories.

    You will need to provide your devcontainer.json file, the associated feature lock metadata, and the text output from your GitHub Codespaces prebuild activity logs.

    Standard prompting often ignores feature digest hashes; this skill uses a formal 'Evidence Labeling' framework to classify every log entry, ensuring the root cause is based on data rather than AI inference.
