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 | $0.00215 | $0.09485 |
| Opus 5.5 | $0.00086 | $0.03794 |
| Sonnet 5.5 | $0.00043 | $0.01897 |
| Haiku 4.5 | $0.00021 | $0.00949 |
Grade A, and why
eos-cost-analysis 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 today.
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 — 517 lines — stays where its author put it; the contents beside it link to each section on GitHub.
EOS Cost Analysis
Discover AWS resources approaching End of Standard Support, calculate Extended Support charges, and generate an actionable cost-impact report.
When to Use This Skill
- User asks about End of Support cost exposure, Extended Support charges, or version-deprecation cost
- User wants to know which resources are incurring or will incur Extended Support charges
- User wants an EOS cost or inventory report / posture assessment across accounts
- User wants a cost-impact report for deprecated service versions
- Proactive scheduled checks for EOS posture across the organization
This skill scopes the EOS cost and inventory picture. It is not an upgrade-execution skill — for EKS pre-upgrade readiness and upgrade planning, use eks-upgrade-readiness; for OpenSearch domain health beyond version lifecycle, use analytics-opensearch-expertise.
Supported Services (Phase 1 — Extended Support Charges)
| Service | Billing Unit | Discovery API |
|---|---|---|
| Amazon EKS | Per cluster/hour | eks:ListClusters, eks:DescribeCluster |
| Amazon RDS/Aurora | Per vCPU/hour per billed instance; per ACU-hour for Aurora Serverless v2 | rds:DescribeDBInstances, rds:DescribeDBClusters |
| AWS Lambda | No direct ES charge (security risk only) | lambda:ListFunctions |
| Amazon ElastiCache | Per node/hour (Redis OSS v4–v6 only) | elasticache:DescribeCacheClusters, elasticache:DescribeReplicationGroups, elasticache:DescribeServerlessCaches |
| Amazon OpenSearch | Per Normalized Instance Hour, or equal to instance cost during an extension period | opensearch:ListDomainNames, opensearch:DescribeDomain |
Which resources are billed, in what unit and how many units are defined in references/billing-rules.md. Follow it for every classification and cost.
What ships with it
10 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.

eos-cost-analysis is a skill published in the GitHub repository aws/tools-for-devops-agent (137 stars, last pushed yesterday), licensed Apache-2.0. It adds 215 tokens to every session and 9,485 once invoked, about $0.0009 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 2026-11-06.
