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 | $0.00034 | $0.00413 |
| Opus 5 | $0.00017 | $0.00206 |
| Sonnet 5 | $0.00007 | $0.00083 |
| Haiku 4.5 | $0.00003 | $0.00041 |
Grade A, and why
azure-cost-optimizer 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 5d 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
Azure Cost Optimizer
Quick Start
Analyze Azure costs and implement optimization strategies to reduce spending while maintaining performance.
Instructions
Step 1: Analyze current costs
# View cost analysis
az cost-management query \
--type Usage \
--dataset-aggregation name="PreTaxCost" function="Sum" \
--dataset-grouping name="ResourceGroup" type="Dimension"
# View costs by service
az cost-management query \
--type Usage \
--dataset-grouping name="ServiceName" type="Dimension"
Step 2: Identify optimization opportunities
Check for unused resources:
- Unattached disks
- Idle virtual machines
- Unused public IPs
- Orphaned network interfaces
Review resource utilization:
- VM CPU and memory usage
- Database DTU utilization
- Storage account access patterns
- Network bandwidth usage
Step 3: Implement cost-saving measures
Reserved Instances:
- 1-year or 3-year commitments
- Up to 72% savings vs pay-as-you-go
- Recommended for stable workloads
Azure Hybrid Benefit:
- Use existing Windows Server licenses
- Use existing SQL Server licenses
- Significant cost savings
Rightsizing:
- Downsize overprovisioned VMs
- Adjust database tiers
- Optimize storage tiers
Spot VMs:
- Up to 90% savings
- Suitable for interruptible workloads
- Batch processing, dev/test

What ships with it
3 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.

azure-cost-optimizer is a skill published in the GitHub repository armanzeroeight/fastagent-plugins (29 stars, last pushed 1mo ago), licensed MIT. It adds 34 tokens to every session and 413 once invoked, about $0.0002 per session on Opus 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.
