env-audit

env-audit is a skill for Claude Code, Codex from greglas75/zuvo. It costs 99 tokens per session (5,092 once invoked), scanned A, original, MIT.

An audit of environment variables and application settings across development, staging, and production. Environment variables are configuration values supplied outside the source code, such as database URLs and secrets.

In plain words
What is it for?
Use it after adding configuration, before a production deployment, while investigating configuration incidents, or when checking a project or one package inside a monorepo, which is a repository containing multiple projects.
Why use it?
It reveals missing or unused settings, exposed secrets, inconsistent environments, unsafe defaults, and configuration that is not checked when the application starts.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

env-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 488 lines — stays where its author put it; the contents beside it link to each section on GitHub.

zuvo:env-audit

Audit environment variable management for completeness, safety, and consistency across development, staging, and production environments. Single-pass execution.

When to use: After adding new env vars, before production deploy, when debugging config-related incidents, onboarding new environments, periodic check. When NOT to use: Secret scanning in source code (/security-audit), CI pipeline config (zuvo:ci-audit), infrastructure (/security-audit).

Mandatory File Loading

Read every file below before starting. Print the checklist.

Argument Parsing

Safety Gates

GATE 1 -- Read-Only

This audit is read-only. The only write target is zuvo/audits/.

FORBIDDEN:

  • Modifying any .env, config, or source file
  • Creating or deleting environment variables
  • Accessing external secret managers (analyze config references only)

GATE 2 -- PII and Secret Censorship

When including env var values in the report:

  • Replace actual values with ***
  • Show only variable names, never values
  • Exception: .env.example placeholder values can be shown as-is

MANDATORY TOOL CALLS — Env Audit Validity Gate

INVALID if any tool below is skipped. "DEFERRED", "N/A", "--secrets-only" NOT valid reasons.

Tool Trigger Skip allowed?
scan_secrets Always NO — KEY: ENV4 secret exposure
search_text Always NO — process.env / os.environ / import.meta.env scan
search_patterns Always NO — ENV2/ENV3/ENV6 anti-patterns
find_references Always NO — ENV2 unused detection
audit_scan Always NO — compound check

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
