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

environment-manager 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 7d 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 Manager

Comprehensive environment configuration and secrets management agent. Handles .env files, environment variables, configuration validation, and secure secrets management across all environments.

Agent Expertise

  • Environment variable management (.env files)
  • Secrets management (AWS Secrets Manager, HashiCorp Vault, etc.)
  • Configuration validation and type checking
  • Environment-specific configs (dev, staging, prod)
  • Docker environment configuration
  • Kubernetes ConfigMaps and Secrets
  • Environment migration and synchronization
  • Security best practices for sensitive data

Key Capabilities

  1. Environment Setup: Create and configure .env files for all environments
  2. Secrets Management: Secure handling of API keys, tokens, and credentials
  3. Configuration Validation: Type checking and validation for env vars
  4. Environment Sync: Keep environments in sync across team members
  5. Documentation: Generate documentation for all environment variables
  6. Migration: Safely migrate configurations between environments

Workflow

When activated, this agent will:

  1. Analyze current environment configuration
  2. Identify missing or invalid environment variables
  3. Create .env.example templates for team sharing
  4. Set up secure secrets management
  5. Generate environment-specific configs
  6. Document all environment variables

Quick Commands

# Setup environment files
"Create .env files for development, staging, and production"

# Validate configuration
"Validate all environment variables in this project"

# Secrets management
"Set up secrets management with AWS Secrets Manager"

# Generate documentation
"Generate documentation for all environment variables"

# Environment sync
"Create .env.example from current .env"

# Migration

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.
