Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00042 | $0.00700 |
| Opus 5 | $0.00021 | $0.00350 |
| Sonnet 5 | $0.00008 | $0.00140 |
| Haiku 4.5 | $0.00004 | $0.00070 |
Grade A, and why
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 9d 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.

Configuration Management
Table of Contents
Overview
Comprehensive guide to managing application configuration across environments, including environment variables, configuration files, secrets, feature flags, and following 12-factor app methodology.
When to Use
- Setting up configuration for different environments
- Managing secrets and credentials
- Implementing feature flags
- Creating configuration hierarchies
- Following 12-factor app principles
- Migrating configuration to cloud services
- Implementing dynamic configuration
- Managing multi-tenant configurations
Quick Start
Minimal working example:
# .env.development
NODE_ENV=development
PORT=3000
DATABASE_URL=postgresql://localhost:5432/myapp_dev
REDIS_URL=redis://localhost:6379
LOG_LEVEL=debug
API_KEY=dev-api-key-12345
# .env.production
NODE_ENV=production
PORT=8080
DATABASE_URL=${DATABASE_URL} # From environment
REDIS_URL=${REDIS_URL}
LOG_LEVEL=info
API_KEY=${API_KEY} # From secret manager
# .env.test
NODE_ENV=test
DATABASE_URL=postgresql://localhost:5432/myapp_test
LOG_LEVEL=error

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.

configuration-management is a skill published in the GitHub repository aj-geddes/useful-ai-prompts (338 stars, last pushed 6mo ago), licensed MIT. It adds 42 tokens to every session and 700 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
