secrets-and-configuration-management

secrets-and-configuration-management is a skill for Claude Code from oborchers/fractional-cto. It costs 83 tokens per session (2,264 once invoked), scanned A, original, MIT.

A guide for storing application credentials and settings, such as passwords, API keys, endpoints, and feature flags, in a secrets manager.

In plain words
What is it for?
Use it when naming secrets, creating database users, rotating credentials, or deciding how applications read configuration at startup.
Why use it?
It reduces the number of places and access patterns developers must maintain when applications need environment-specific configuration.

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

secrets-and-configuration-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 12d 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.

One Secret Per Service, One Path Everywhere

The most common infrastructure mistake with credentials is over-engineering the separation. Splitting database passwords into a secrets manager, endpoints into a parameter store, and feature flags into environment variables creates three access patterns, three IAM policies, and a Terraform apply every time you change a connection string.

Put everything in one secret per service. One JSON blob containing every environment variable the service needs -- credentials, endpoints, flags, all of it. Store it in a secrets manager with customer-managed encryption. The application reads and parses the secret at startup. Done.

Core Principles

  1. One secret per service. Each service has exactly one secret: /{service}/env. It contains a JSON object with every env var the service needs -- database passwords next to database hosts, API keys next to feature flags. No separation between "secrets" and "configuration."

  2. Account = environment. The secret path is /{service}/env in every account. Dev account, prod account, staging account -- same path. The AWS account provides the isolation (see multi-account-from-day-one skill). Application code never needs to know which environment it runs in. This mirrors the internal DNS pattern (see network-architecture skill) where db.internal resolves to the right database per VPC -- same hostname everywhere, different values per environment.

  3. Change without Terraform. Update the secret value in the console or CLI, force a container redeploy. No plan/apply cycle for config changes. Terraform creates the secret resource and sets the initial value; the team manages the value thereafter.

  4. Customer-managed encryption. Every secret is encrypted with a KMS key you control, not the provider default. This enables key rotation, cross-account access policies, and decryption audit trails.

  5. Rotation is a spectrum. Database credentials can auto-rotate if you invest in the rotation Lambda. Third-party API keys (Stripe, SendGrid) rarely rotate in practice. Don't let perfect rotation block shipping. Start with KMS encryption and proper access scoping; add rotation when it matters.

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.
