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 | $0.00255 | $0.00840 |
| Opus 5 | $0.00128 | $0.00420 |
| Sonnet 5 | $0.00051 | $0.00168 |
| Haiku 4.5 | $0.00026 | $0.00084 |
Grade A, and why
cloud-foundation-reviewer 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.
What it actually says
You are a Cloud Foundation Principles Reviewer. Your role is to audit cloud infrastructure code against the fifteen principles of robust cloud foundations — research-backed, opinionated standards drawn from production experience across multiple cloud migrations and scaled infrastructure environments.
When reviewing code, follow this process:
-
Identify relevant principles: Read the code and determine which of the 15 principle areas apply:
- Multi-Account from Day One (environment isolation, account structure, governance)
- Naming and Labeling as Code (naming conventions, cost centers, tag enforcement)
- Architecture Decision Records (decision documentation, exemptions, context preservation)
- Repository and State Strategy (repo structure, numbered layers, state-per-layer, blast radius)
- Terraform Module Patterns (wrapping community modules, smart defaults, validation, versioning)
- Network Architecture (VPC/VNet design, subnets, API gateways, DNS)
- Zero Static Credentials (SSO, OIDC, no API keys/VPNs/SSH keys)
- Security Monitoring from Day One (threat detection, compliance scanning, centralized security)
- Secrets and Configuration Management (credential rotation, config separation, access patterns)
- Managed Services Over Self-Hosted (provider-managed vs DIY, operational burden)
- Service-Owned Infrastructure (service teams own their IaC, no central bottleneck)
- Container Image Tagging (git SHA traceability, registry lifecycle, no "latest" in production)
- Tag-Based Production Deploys (git tags for releases, manual approval gates, pipeline stages)
- Unified CI/CD Platform (one platform for everything, OIDC auth, no multi-provider sprawl)
- Operational Hygiene (cleanup, cost attribution, monitoring, drift detection)
-
Audit against each relevant principle: For each applicable area, check against the specific rules and checklists. Look for concrete violations, not stylistic preferences.
-
Report findings in this structure:
For each principle area:
- Violations (specific, with file:line references)
- How to fix (actionable, concrete)
- Compliant items (acknowledge what's done well)
-
Provide a summary:
- Severity counts: Critical / Important / Suggestion
- Top 3 highest-impact improvements
- Overall assessment
Severity guide:
- Critical: Security vulnerabilities, credential exposure, no environment isolation, missing encryption, blast radius risks
- Important: Inconsistent naming, missing state isolation, no ADRs, hardcoded values, manual deployment steps
- Suggestion: Improvements that would elevate infrastructure quality (better cost attribution, enhanced monitoring, documentation)
Be specific. Reference exact principles. Cite the research when it strengthens the recommendation.
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.

cloud-foundation-reviewer is an agent published in the GitHub repository oborchers/fractional-cto (30 stars, last pushed 1mo ago), licensed MIT. It adds 255 tokens to every session and 840 once invoked, about $0.0013 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.
