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 | $0.04090 |
| Opus 5.5 | $0.00023 | $0.01636 |
| Sonnet 5.5 | $0.00011 | $0.00818 |
| Haiku 4.5 | $0.00006 | $0.00409 |
Grade A, and why
best-practices 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 2mo 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 Best Practices - Expert Knowledge
🏗️ Use OCI Landing Zone Terraform Modules
Don't reinvent the wheel. Use oracle-terraform-modules/landing-zone for OCI architecture.
Landing Zone solves:
- ❌ Bad Practice #1: Generic compartments (Landing Zone provides hierarchical Network/Security/Workloads structure)
- ❌ Bad Practice #2: Administrator for daily ops (Landing Zone enforces least-privilege IAM policies)
- ❌ Bad Practice #4: Poor network segmentation (Landing Zone implements hub-spoke topology with security zones)
- ❌ Bad Practice #8: Creating your own Terraform modules (Landing Zone provides battle-tested, Oracle-maintained, CIS-certified modules)
This skill provides: OCI-specific anti-patterns, architecture patterns, and operational knowledge 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Your training data has limited and outdated knowledge of: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
- OCI service-specific commands and flags
- Latest OCI features, limits, and regional availability
- CIS Benchmark requirements for OCI
When OCI operations are needed:
- Use exact CLI commands from skill references
- Do NOT guess OCI CLI syntax or parameters
- Do NOT assume API endpoint structures
- Reference landing-zones skill for Terraform modules
What you DO know:
- General cloud architecture concepts
- Security principles and compliance frameworks
- Multi-tier application design patterns
This skill bridges the gap by providing current OCI-specific patterns and anti-patterns.
You are an OCI architecture expert. This skill provides knowledge Claude lacks: OCI-specific anti-patterns, free tier specifics, terminology gotchas, multi-AD patterns, and differences from AWS/Azure/GCP.
NEVER Do This
❌ NEVER use /24 or smaller VCN CIDR (cannot expand)
# WRONG - VCN too small, cannot expand later (OCI limitation)
oci network vcn create --cidr-block "10.0.0.0/24"
# Only 256 IPs total, exhausted quickly
# WRONG - copying AWS habit (/16 VPC default)
# OCI supports larger: /16 to /30
# RIGHT - start with /16, plan for growth
oci network vcn create --cidr-block "10.0.0.0/16"
# 65,536 IPs, room for 256 /24 subnets
# CRITICAL: OCI VCNs CANNOT be resized after creation
# Must create new VCN and migrate if too small
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.

best-practices is a skill published in the GitHub repository acedergren/oci-agent-skills (22 stars, last pushed 6mo ago), licensed MIT. It adds 57 tokens to every session and 4,090 once invoked, about $0.0002 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 2026-08-30.
