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 | $0.00057 | $0.04104 |
| Opus 5 | $0.00028 | $0.02052 |
| Sonnet 5 | $0.00011 | $0.00821 |
| Haiku 4.5 | $0.00006 | $0.00410 |
Grade A, and why
finops-cost-optimization 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 10d 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.

OCI FinOps - Expert Knowledge
🏗️ Use OCI Landing Zone Terraform Modules
Don't reinvent the wheel. Use oracle-terraform-modules/landing-zone for cost-optimized infrastructure.
Landing Zone solves:
- ❌ Bad Practice #3: Internet breakout from spoke networks (Egress cost waste $3k-5k/month; Landing Zone uses hub-spoke with centralized NAT/Firewall)
- ❌ Bad Practice #8: Creating your own Terraform modules (Maintenance cost; Landing Zone is Oracle-maintained, CIS-certified, no technical debt)
- ❌ Bad Practice #10: No monitoring (Blind spending; Landing Zone auto-configures budget alerts, usage notifications, and cost tracking)
This skill provides: Cost optimization strategies, hidden cost traps, and savings calculations for resources deployed WITHIN a Landing Zone.
⚠️ OCI CLI/API Knowledge Gap
You don't know OCI CLI commands or OCI API structure.
Your training data has limited and outdated knowledge of:
- OCI CLI syntax and parameters (updates monthly)
- OCI API endpoints and request/response formats
- Cost Management CLI operations (
oci usage-api) - Current OCI pricing (changes frequently)
- Universal Credits consumption rates and SKUs
When OCI operations are needed:
- Use exact CLI commands from skill references
- Do NOT guess OCI CLI syntax or parameters
- Do NOT assume current pricing - always verify
- Reference official Oracle pricing calculator
What you DO know:
- General cloud cost optimization principles
- FinOps frameworks and methodologies
- Resource right-sizing concepts
This skill bridges the gap by providing current OCI-specific cost traps and optimization patterns.
You are an OCI cost optimization expert. This skill provides knowledge Claude lacks: hidden cost traps, Universal Credits gotchas, exact savings calculations, free tier maximization, and OCI-specific billing nuances.
NEVER Do This
❌ NEVER ignore orphaned boot volumes (silent cost drain)
# Default OCI behavior: Boot volumes PRESERVED after instance termination
oci compute instance terminate --instance-id <ocid> --force
# Instance deleted, but boot volume remains (charges continue!)
Cost trap:
- Boot volume: 50 GB × $0.025/GB/mo = $1.25/month per instance
- 20 terminated test instances = $25/month wasted
- Over 1 year: $300 wasted on deleted instances
# RIGHT - explicitly delete boot volume
oci compute instance terminate \
--instance-id <ocid> \
--preserve-boot-volume false # Critical flag!
# Or in Terraform:
resource "oci_core_instance" "dev" {
preserve_boot_volume = false # Must set explicitly
}
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.

finops-cost-optimization is a skill published in the GitHub repository acedergren/oci-agent-skills (20 stars, last pushed 4mo ago), licensed MIT. It adds 57 tokens to every session and 4,104 once invoked, about $0.0003 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.
