iac

iac is a skill for Claude Code, Codex from adonai-labs/agent-runway. It costs 90 tokens per session (1,416 once invoked), scanned A, original, MIT.

A guide for defining and managing cloud infrastructure with code, focused on .NET applications running on Microsoft Azure. It covers Bicep and Terraform, which are tools for describing cloud resources in files.

In plain words
What is it for?
Use it to create or review Azure resources, set up environments, configure services such as App Service and SQL Database, or manage secrets with Key Vault.
Why use it?
It provides a structured way to review infrastructure changes and account for risk, reversibility, uncertainty, and rollback.

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

iac 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 10d 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

Invoke Command

/iac <what you need>

Examples:

  • /iac new App Service + SQL Database for the orders service
  • /iac review infra/main.bicep
  • /iac add Key Vault and update app settings references
  • /iac create dev and prod parameter files

Workflow

Follow these steps in order.

Step 0 - Risk Classification and Routing Gate

Before any IaC change, classify:

  • Impact: low/medium/high
  • Reversibility: reversible/hard-to-reverse/irreversible
  • Uncertainty: low/medium/high
  • Cost of error: low/medium/high

Contrarian trigger (any true):

  • impact is high and reversibility is hard-to-reverse or irreversible
  • uncertainty is high
  • migration/cutover with ambiguous rollback
  • architecture decision with multiple viable infrastructure patterns

Execution mode:

  • Execution-only: low risk + reversible + low uncertainty
  • Execution+validation: medium risk or multi-resource change
  • Execution+contrarian: contrarian trigger active

Policy:

  • Execution-only: continue with minimal questions and minimal process overhead.
  • Execution+validation: continue with normal IaC workflow.
  • Execution+contrarian: run mandatory contrarian review before writing IaC.

Decision action table:

Profile Action
High impact + irreversible + high uncertainty Block - stop and escalate before changes
Medium risk profile Warn - continue only with explicit risk notes and validation checks
Low risk + reversible + low uncertainty Execute - use short path

Step 0.5 - Contrarian Review (Required when triggered)

When triggered, document:

  • recommended infrastructure approach
  • strongest counter-argument
  • at least one viable alternative
  • top operational/security risks and invalidation signals
  • verdict: Go, Go with conditions, or Stop

If verdict is Stop, halt and escalate. If verdict is Go with conditions, convert conditions to explicit validation checks.

What ships with it

2 files 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.

Changes

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.
