mav-bp-environment-management

mav-bp-environment-management is a skill for Claude Code from thermiteau/maverick. It costs 45 tokens per session (849 once invoked), scanned A, original, Apache-2.0.

A set of rules for creating reproducible development environments and keeping local, staging, and production setups consistent. It covers pinned tool versions, environment variables, containers, onboarding, and local service dependencies.

In plain words
What is it for?
Use it when setting up or reviewing a project environment. It helps define one-command onboarding, pinned runtimes and container images, documented .env.example files, and matching local database or service versions.
Why use it?
It reduces setup problems and differences between a developer's machine and production. It also keeps secrets out of version control and discourages replacing production services with incompatible local substitutes.

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

mav-bp-environment-management 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 11d 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.

Environment Management Standards

Maverick's hard rules for reproducible local development environments and environment-specific configuration.

Maverick's Rules

  • Fresh clone to running app in under 30 minutes, via one setup command — onboarding friction is a defect. Setup instructions must not require asking a team member; test them in CI or on a clean machine.
  • Pin everything — language/tool versions (.node-version, .tool-versions, etc.) and container image versions (postgres:16.2, never latest).
  • No environment names in application codeif (env === "production") is a code smell; one code path, config injected via env vars. Sole exception: a single log-verbosity/error-reporting config check at initialisation.
  • Database parity is non-negotiable — same engine and major version locally (via Docker) as production. Never substitute SQLite for PostgreSQL in dev. Prefer real local service instances or emulators (LocalStack, Azurite); mock only as a last resort.
  • .env discipline.env.example is committed and lists every env var the application reads, each with a description; sensitive values blank, safe defaults provided. .env is gitignored. .env.production never exists locally — production config comes from the deployment platform. Validate required env vars at startup and fail fast.
  • Docker Compose — bind ports to localhost only (127.0.0.1:5432:5432); include health checks so dependents wait for readiness.

.env.example format:

DATABASE_URL=              # PostgreSQL connection string (e.g., postgres://user:pass@localhost:5432/mydb)
STRIPE_API_KEY=            # Stripe secret key (starts with sk_test_ or sk_live_)
LOG_LEVEL=error            # error | warn | debug
PORT=3000                  # HTTP server port

Project Implementation Lookup

Check for docs/maverick/skills/environment-management/SKILL.md. If present, read it — it wins on specifics (library, config, conventions). If missing, proceed with these standards and note the gap in your summary.

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.
