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 | $0.00171 | $0.01174 |
| Opus 5 | $0.00086 | $0.00587 |
| Sonnet 5 | $0.00034 | $0.00235 |
| Haiku 4.5 | $0.00017 | $0.00117 |
Grade A, and why
oracle-cloud 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.

Oracle Cloud Infrastructure (OCI)
Core Capabilities
Provides expert guidance for Oracle Cloud Infrastructure across all major services:
- Compute Services - VM instances, bare metal, autoscaling, instance pools
- Networking - Virtual Cloud Networks (VCN), subnets, security lists, route tables, load balancers, VPN
- Storage - Block volumes, object storage, file storage, archive storage
- Database Services - Autonomous Database, MySQL, PostgreSQL, NoSQL, MongoDB
- Container & Kubernetes - Oracle Kubernetes Engine (OKE), container instances, registries
- Identity & Access Management - Users, groups, policies, federation, MFA
- Infrastructure as Code - Terraform OCI provider, Resource Manager, stacks
- Cost Management - Budgets, cost analysis, resource tagging, rightsizing
Best Practices
Compute
- Use flexible shapes for cost optimization
- Enable boot volume backups and configure lifecycle policies
- Use instance pools with autoscaling for dynamic workloads
- Implement proper tagging for resource management
- Leverage availability domains for high availability
Networking
- Design VCN with proper CIDR blocks (avoid overlaps)
- Use security lists and network security groups together
- Implement private subnets for databases and application tiers
- Enable DRG (Dynamic Routing Gateway) for hybrid connectivity
- Configure load balancer health checks with appropriate intervals
Storage
- Use block volumes with appropriate performance tiers
- Implement lifecycle policies for object storage cost savings
- Enable encryption at rest for all storage services
- Configure regular backups with retention policies
- Use file storage for shared application data
Database
- Use Autonomous Database for automatic management and tuning
- Enable automatic backups with point-in-time recovery
- Configure connection pooling and TLS encryption
- Implement proper IAM policies for database access
- Monitor database metrics and set up alerts
What ships with it
6 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.

oracle-cloud is a skill published in the GitHub repository DauQuangThanh/hanoi-rainbow (17 stars, last pushed 7mo ago), licensed MIT. It adds 171 tokens to every session and 1,174 once invoked, about $0.0009 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 2026-08-31.
