manage-secrets-env

manage-secrets-env is a skill for Claude Code from subinium/vibesubin. It costs 95 tokens per session (6,574 once invoked), scanned A, original, MIT.

A project-management skill for deciding where secrets and environment-specific settings should live, such as in a constant, a .env file, a CI secret, or an environment variable. It also covers files such as .env.example and .gitignore.

In plain words
What is it for?
It is for adding, changing, rotating, removing, moving, and auditing secrets and environment variables, while setting up the files that help keep them out of Git.
Why use it?
It reduces the risk of exposing passwords, tokens, or other private settings in source control or the wrong deployment environment.

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

manage-secrets-env 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 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/check-env-drift.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 339 lines — stays where its author put it; the contents beside it link to each section on GitHub.

manage-secrets-env

Every project has two kinds of structural decisions. Some are low-stakes — which branch naming, which directory layout — and a mistake costs a little friction. Some are high-stakes — where a database password lives, whether .env is tracked, whether a production token is in a build-time variable — and a mistake costs an incident.

This skill owns the high-stakes slice: secrets, environment variables, and the gitignore that protects them. The low-stakes conventions (branches, directories, dep pinning, path portability) live in project-conventions. Splitting them this way means the operator can trigger the right depth of care for the right question.

The principle: the safest default is the one the operator doesn't have to invent. When they ask "where does my DB password go?", answer immediately, explain in one sentence, and offer to scaffold.

State assumptions — before acting

Before starting the procedure, write an explicit Assumptions block. Don't pick silently between interpretations; surface the choice. If any assumption is wrong or ambiguous, pause and ask — do not proceed on a guess.

Required block:

Assumptions:
- Environment tier:  <dev | staging | prod — affects which bucket rules apply>
- .env.example:      <present | missing (drift check cannot run yet, operator must scaffold first)>
- Tracked secrets:   <none detected | FOUND — this is an incident; hand off to audit-security immediately, do not proceed with lifecycle workflows>
- Lifecycle action:  <audit only | add | update | rotate | remove | migrate | provision new env>

Typical items for this skill:

  • Current environment tier (dev / staging / prod) — affects which bucket rules apply
  • Whether .env.example exists — affects drift-check baseline
  • Whether any secret-shaped value is tracked in git or git history (this is always an incident if true)

Stop-and-ask triggers:

  • A tracked secret is detected — immediate hand-off to audit-security incident mode, do NOT proceed with normal lifecycle workflows
  • Operator asks to "rotate" without naming which secret — list the candidates and ask

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.
