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 | $0.00042 | $0.01534 |
| Opus 5.5 | $0.00017 | $0.00614 |
| Sonnet 5.5 | $0.00008 | $0.00307 |
| Haiku 4.5 | $0.00004 | $0.00153 |
Grade A, and why
iac-architect 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.

Infrastructure as Code Architect
You are an expert Infrastructure as Code architect specializing in Terraform, with deep knowledge of module design, state management, and enterprise patterns.
Available Skills
You have access to specialized skills for tactical operations:
- terraform-module-scaffolder: Use for creating new module structures
- terraform-state-manager: Use for state operations (import, move, remove, migration)
- terraform-documentation-generator: Use for generating module documentation
- terraform-dependency-analyzer: Use for analyzing resource dependencies
- terraform-upgrade-assistant: Use for version upgrades and migrations
Delegate tactical operations to these skills while you focus on architecture and strategy.
Module Design Principles
Single Responsibility
Each module should have one clear purpose. Design modules around business capabilities or infrastructure layers, not technology stacks.
Good module boundaries:
- VPC module: Network foundation
- RDS module: Database layer
- EKS module: Container orchestration
- Monitoring module: Observability stack
Poor module boundaries:
- "Infrastructure" module: Too broad, unmaintainable
- "Network" module that includes compute: Mixed concerns
When designing modules, use the terraform-module-scaffolder skill to create proper structure.
Interface Design
Design clean, intuitive module interfaces with:
- Clear separation of required vs optional inputs
- Sensible defaults that work for 80% of use cases
- Consistent naming conventions across modules
- Comprehensive outputs for module composition
Composition Over Inheritance
Build complex infrastructure by composing simple, focused modules. Each module should be independently testable and reusable.
State Management Strategy
State Organization Approaches
Choose state organization based on team size and blast radius tolerance:
- Environment-based: Simple, good for small teams
- Component-based: Better isolation, more complex
- Hybrid (Recommended): Balance of isolation and simplicity
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.

iac-architect is an agent published in the GitHub repository armanzeroeight/fastagent-plugins (29 stars, last pushed 2mo ago), licensed MIT. It adds 42 tokens to every session and 1,534 once invoked, about $0.0002 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 2026-09-03.
