    Example session with this skill installed

    Audit my .env.example file against the src/ directory and tell me if I've missed any variables or if any are no longer needed.

    • Read your context and instructions
    • Compiled the env example sync

    I have completed the audit comparing .env.example against the references found in your src/ directory and configuration files.

    .env.example Sync Report

    Summary
    .env.example variables: 8 | Referenced: 9 | Matched: 7 | Missing: 2 | Orphaned: 1 | Dynamic/unresolved: 1

    Missing Variables

    Variables found in source but missing from .env.example.

    VariableSourceContext
    STRIPE_WEBHOOK_SECRETsrc/api/webhooks.ts:12Missing in example
    REDIS_TLS_ENABLEDsrc/lib/redis.ts:4Missing in example

    Orphaned Variables

    Declared in .env.example but no references were found in the inspected source.

    VariableDeclared InNotes
    LEGACY_API_KEY.env.example:15Potentially deployment-managed or obsolete

    Dynamic / Unresolved

    Static analysis found environment access, but the variable names are determined at runtime.

    • process.env[prefix + "_TOKEN"] at src/auth/providers.ts:22

    Recommended Actions

    1. Add STRIPE_WEBHOOK_SECRET and REDIS_TLS_ENABLED to .env.example with placeholder values.
    2. Verify if LEGACY_API_KEY is used by CI/CD or external scripts before removal.
    3. Manually audit src/auth/providers.ts to ensure all dynamic token variants are documented.

    Next steps

    • Would you like me to append the missing variables to .env.example for you?
    • Should I check for these variables in docker-compose.yml or other config files?

    About this skill

    The problem

    Developers often forget to update .env.example when adding new environment variables to source code. This leads to broken onboarding experiences for new contributors and missing configuration in CI/CD pipelines.

    What it does

    • Scans source code for process.env, os.environ, and language-specific equivalents to identify required variables.
    • Parses .env.example to extract declared variable names while ignoring their values.
    • Identifies missing variables that are used in code but absent from the example file.
    • Flags orphaned variables present in the example file but not found in the codebase.
    • Detects dynamic environment access that cannot be statically analyzed for manual review.

    Frameworks & tools

    Works with Node.js, Python, Ruby, PHP, Go, Java, and Rust. Supports framework conventions for Next.js and Vite.

    Why this beats prompting it yourself

    Generic prompts often hallucinate environment variable names or fail to scan configuration files like docker-compose.yml. This skill follows strict security protocols to never leak or display actual secret values during the audit process.

    Use cases

    • Pre-commit audits to ensure .env.example stays in sync with feature branches.
    • Onboarding troubleshooting when a project fails to start due to missing config.
    • Cleaning up legacy repositories by identifying potentially obsolete environment declarations.

    Known limitations

    Static analysis cannot detect variables accessed via dynamic string concatenation or runtime reflection. It does not scan for actual secrets or validate credential correctness.
