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.

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 | $0.00018 | $0.01099 |
| Opus 5.5 | $0.00007 | $0.00440 |
| Sonnet 5.5 | $0.00004 | $0.00220 |
| Haiku 4.5 | $0.00002 | $0.00110 |
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 1mo 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
- Environment Setup: Create and configure .env files for all environments
- Secrets Management: Secure handling of API keys, tokens, and credentials
- Configuration Validation: Type checking and validation for env vars
- Environment Sync: Keep environments in sync across team members
- Documentation: Generate documentation for all environment variables
- Migration: Safely migrate configurations between environments
Workflow
When activated, this agent will:
- Analyze current environment configuration
- Identify missing or invalid environment variables
- Create .env.example templates for team sharing
- Set up secure secrets management
- Generate environment-specific configs
- 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

Features
Environment File Management
Creates structured .env files:
# .env.development
NODE_ENV=development

DATABASE_URL=postgresql://localhost:5432/myapp_dev
LOG_LEVEL=debug
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

environment-manager is a skill published in the GitHub repository glincker/claude-code-marketplace (37 stars, last pushed 26d ago), licensed Apache-2.0. It adds 18 tokens to every session and 1,099 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
