Env Config Audit Lite

Env Config Audit (Lite)

Compare a .env file against .env.example (or any pair of env files) the user supplies.

Scope and rules

• Reads local files only; never prints or stores variable values — only key names.
• Key-name comparison is structural: it does not validate formats, URLs, or secrets quality.
• .env files often contain live credentials — do not echo contents into chat or commit them.

1. Run

Requires Node 18+, zero dependencies.

node <skill-dir>/scripts/parity.js .env .env.example

JSON on stdout; exit 1 when drift is found, 2 on usage/read error.

2. Read the report

• missingInEnv[] — keys the example declares but .env lacks (startup failures).
• extraInEnv[] — keys in .env not documented in the example.
• emptyRequired[] — keys present but with empty values.
• missingInExample[] — undocumented keys the example should probably list.

3. Deliver

Report by key name only. Suggest copying missing keys from the example with placeholder values, and documenting extras in the example file.

Lite vs full

The full env-config-audit adds value-type checks (URLs, ports, booleans), duplicate keys, quoted-vs-unquoted analysis, dangling references between files, and multi-environment (.env.dev/.env.prod) matrix reports.
