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 | $0.00012 | $0.00903 |
| Opus 5.5 | $0.00005 | $0.00361 |
| Sonnet 5.5 | $0.00002 | $0.00181 |
| Haiku 4.5 | $0.00001 | $0.00090 |
Grade A, and why
validate-template 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Validate CloudFormation Template
Context
- Current directory: !
pwd - Available CloudFormation templates: !
find . -name "*.yaml" -o -name "*.yml" -o -name "*.json" | grep -E "(template|stack|cfn)" | head -20 - AWS CLI version: !
aws --version 2>&1 || echo "AWS CLI not installed" - cfn-lint installed: !
cfn-lint --version 2>&1 || echo "cfn-lint not installed"
Your Task
Validate the specified CloudFormation template for syntax errors, security issues, and best practices violations.
Arguments
$1: Path to CloudFormation template file (required)
Steps
-
Verify template file exists
- Check if the specified file exists
- If not provided, list available templates and ask user to specify
-
Run AWS CloudFormation validation
aws cloudformation validate-template --template-body file://$1- Check for syntax errors
- Verify template structure
- Report any AWS validation errors
-
Run cfn-lint validation (if available)
cfn-lint $1- Check for best practices violations
- Identify resource property issues
- Report warnings and errors
- If cfn-lint not installed, suggest:
pip install cfn-lint
-
Run cfn-nag security scan (if available)
cfn_nag_scan --input-path $1- Check for security issues
- Identify overly permissive IAM policies
- Check for unencrypted resources
- Report security warnings and failures
- If cfn-nag not installed, suggest:
gem install cfn-nag
-
Analyze and summarize results
- Categorize issues by severity (errors, warnings, info)
- Highlight critical security issues
- Provide specific recommendations for fixes
- Show line numbers for issues when available
-
Provide actionable recommendations
- For each issue, explain what's wrong
- Suggest specific fixes with code examples
- Prioritize by impact (high/medium/low)
- Reference best practices documentation
Output Format
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.
- 2mo ago First seen · 147 lines · 12 tokens per session scan A 6211843d0a58
validate-template is a command published in the GitHub repository armanzeroeight/fastagent-plugins (29 stars, last pushed 3mo ago), licensed MIT. It adds 12 tokens to every session and 903 once invoked, about $0.0000 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.
