What it does
Cloudformation Best Practices is an agent skill from aiskillstore/marketplace. CloudFormation template optimization, nested stacks, drift detection, and production-ready patterns. Use when writing or reviewing CF templates.
Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `skill-report.json`).
It sits in DevOps & Cloud, covering Infrastructure as code and GitOps. It works with AWS CloudFormation. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- Reviewing CF templates
- Tasks that involve Infrastructure as code
- Tasks that involve GitOps
Example prompts
- “/cloudformation-best-practices”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Use YAML over JSON for readability.
- Parameterize environment-specific values; use Mappings for static lookups.
- Apply DeletionPolicy: Retain on stateful resources (RDS, S3, DynamoDB).
- Use Conditions to support multi-environment templates.
- Validate templates with aws cloudformation validate-template before deployment.
- Prefer !Sub over !Join for string interpolation.
What it can do on your machine
Read from SKILL.md and the folder at commit 755bc35. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
aws
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use aws, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Cloudformation Best Practices loads about 617 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 190 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 190 words (~617 tokens).
“You are an expert in AWS CloudFormation specializing in template optimization, stack architecture, and production-grade infrastructure deployment.”
