use-aws-mini-stack-emulator

use-aws-mini-stack-emulator is a skill for Claude Code, Codex from soulcodex/agentic. It costs 49 tokens per session (495 once invoked), scanned A, original, MIT.

A guide for using a lightweight local imitation of AWS services while developing Terraform, a tool for defining cloud infrastructure as code. It explains what can be checked locally and what still needs verification in real AWS.

In plain words
What is it for?
Use it for local Terraform syntax, interpolation, module wiring, dependencies, and selected resource checks before moving to real-AWS validation.
Why use it?
It gives faster feedback on suitable Terraform changes while making the limits of local imitation clear before real cloud operations are reviewed or run.

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

use-aws-mini-stack-emulator 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 3d 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.

What it actually says

Use AWS Mini Stack Emulator Skill

Use local AWS emulation to accelerate Terraform feedback loops where appropriate.

Always pair this skill with terraform-risk-playbook. That skill is authoritative for the response contract, failure-mode classification, version/runtime guards, validation chain, and rollback notes.

Step 1 - Select Emulator Scope

Use emulator-compatibility-matrix.md to decide what is safe to validate locally.

Classify each planned check as:

  • emulator-suitable
  • partial confidence only
  • requires real AWS

Step 2 - Configure Provider and Endpoints for Local Runs

Keep local endpoint wiring isolated from production configuration. Use explicit variables or per-environment override files for emulator endpoint settings. Use local state or terraform init -backend=false for emulator-first CI checks to avoid touching shared remote backends.

Step 3 - Validate Fast Feedback Cases

Good emulator targets:

  • syntax and interpolation mistakes
  • module wiring and basic dependencies
  • selected resource contract checks where behavior is reliably emulated

Step 4 - Document Gaps and Escalate

Always document unsupported services/behaviors and escalate those tests to real AWS validation before merge.

Step 5 - Keep Scope Boundary Explicit

This skill is for local acceleration only. It does not replace real AWS plan/apply verification for production-impacting infrastructure.

It cannot prove:

  • production backend locking or state migration behavior
  • IAM or service semantics that emulators do not model faithfully
  • reviewed plan artifact and approval parity in CI
  • final confidence for production-impacting provider/runtime upgrades

Avoid overlap with docker-compose-local-setup: this skill covers Terraform + AWS emulation behavior, not generic multi-service compose orchestration design.

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.
