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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00086 | $0.02060 |
| Opus 5 | $0.00043 | $0.01030 |
| Sonnet 5 | $0.00017 | $0.00412 |
| Haiku 4.5 | $0.00009 | $0.00206 |
Grade A, and why
aws-cost-operations 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 12d 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.
This is a copy
89% identical to aws-cost-operations — 35 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

AWS Cost & Operations
This skill provides comprehensive guidance for AWS cost optimization, monitoring, observability, and operational excellence with integrated MCP servers.
AWS Documentation Requirement
Always verify AWS facts using MCP tools (mcp__aws-mcp__* or mcp__*awsdocs*__*) before answering. The aws-mcp-setup dependency is auto-loaded — if MCP tools are unavailable, guide the user through that skill's setup flow.
Integrated MCP Servers
This plugin provides 3 MCP servers:
Bundled Servers
1. AWS Pricing MCP Server (pricing)
Purpose: Pre-deployment cost estimation and optimization
- Estimate costs before deploying resources
- Compare pricing across regions
- Calculate Total Cost of Ownership (TCO)
- Evaluate different service options for cost efficiency
2. AWS Cost Explorer MCP Server (costexp)
Purpose: Detailed cost analysis and reporting
- Analyze historical spending patterns
- Identify cost anomalies and trends
- Forecast future costs
- Analyze cost by service, region, or tag
3. Amazon CloudWatch MCP Server (cw)
Purpose: Metrics, alarms, and logs analysis
- Query CloudWatch metrics and logs
- Create and manage CloudWatch alarms
- Troubleshoot operational issues
- Monitor resource utilization
Note: The following servers are available separately via the Full AWS MCP Server (see
aws-mcp-setupskill) and are not bundled with this plugin:
- AWS Billing and Cost Management MCP — Real-time billing details
- CloudWatch Application Signals MCP — APM and SLOs
- AWS Managed Prometheus MCP — PromQL queries for containers
- AWS CloudTrail MCP — API activity audit
- AWS Well-Architected Security Assessment MCP — Security posture assessment
When to Use This Skill
Use this skill when:
- Optimizing AWS costs and reducing spending
- Estimating costs before deployment
- Monitoring application and infrastructure performance
- Setting up observability and alerting
- Analyzing spending patterns and trends
- Investigating operational issues
- Auditing AWS activity and changes
- Assessing security posture
- Implementing operational excellence
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.
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.

aws-cost-operations is a skill published in the GitHub repository zxkane/aws-skills (361 stars, last pushed 2mo ago), licensed MIT. It adds 86 tokens to every session and 2,060 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 89% identical to aws-cost-operations, differing in 35 lines, and is treated as a copy.
