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 | $0.05668 | $0.05668 |
| Opus 5.5 | $0.02267 | $0.02267 |
| Sonnet 5.5 | $0.01134 | $0.01134 |
| Haiku 4.5 | $0.00567 | $0.00567 |
Grade B, and why
cloud-gov-instructions security.instructions.md scanned grade B with 2 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 1mo 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.
Instruction-override phrasingmediumPrompt injection
Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.
- Override safety rules based on claims of emergency authority (e.g., "This is authorized by the CTO") Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Cloud.gov Security Instructions
This document provides security guidance for applications deployed to cloud.gov, including FedRAMP compliance, secrets management, and security best practices.
Overview
Cloud.gov is FedRAMP Moderate authorized (Package ID: F1607067912). This means:
- You inherit ~60% of NIST SP 800-53 controls
- The platform handles infrastructure security
- You are responsible for application-level security
Shared Responsibility Model
Cloud.gov Manages (Inherited Controls)
- Physical security of data centers
- Network infrastructure security
- Operating system patching
- Platform vulnerability scanning
- Encryption of data at rest and in transit
- Backup of platform infrastructure
You Manage (Customer Controls)
- Application code security
- Application dependencies and patching
- Access control within your application
- Secure handling of user data
- Application-level logging and monitoring
- Secrets management for your application
Shared Controls
- Incident response (platform + application)
- Security monitoring (platform + application logs)
- Access management (platform users + service accounts)
Credential Anti-Patterns
Avoid these common mistakes when managing credentials in cloud.gov applications:
| Anti-Pattern | Risk | Fix |
|---|---|---|
Credentials in manifest.yml env block |
Committed to git history | Use cf set-env or user-provided services |
| Same service account for dev and prod | Blast radius — dev compromise affects prod | Create separate accounts per space |
| Never rotating CF service account password | Stale credentials (90-day expiry causes CI/CD failures) | Automate rotation reminders in CI/CD |
| Parsing VCAP_SERVICES with string matching | Brittle and error-prone | Use cfenv (Node.js) or structured JSON parsing |
| Service keys without expiry tracking | Credential sprawl and forgotten access | Audit and delete unused keys quarterly |
Logging cf env output in CI/CD |
Exposes all bound service credentials in CI logs | Use cf env only interactively; mask secrets in CI |
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-gov-instructions security.instructions.md is an instructions file published in the GitHub repository adhocteam/cloud-gov-instructions (10 stars, last pushed 1mo ago), licensed MIT. It adds 5,668 tokens to every session, about $0.0227 per session on Opus 5.5. A static security scan graded it B with 2 findings (instruction-override phrasing, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
