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 | $0.00223 | $0.00223 |
| Opus 5.5 | $0.00089 | $0.00089 |
| Sonnet 5.5 | $0.00045 | $0.00045 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
windsurfrules 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 17d 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
Windsurf & Cascade Directives - Generated by AgentForge
Project: agentforge
Global Instructions
- Write minimal, concise, and robust code. Avoid over-engineering (YAGNI).
- Follow language idioms and leverage the standard library before third-party abstractions.
- Never compromise on security, input validation, error handling, or accessibility.
- Maintain existing style, patterns, and architectural conventions across edits.
Stack Details
- Languages: TypeScript, JavaScript
- Frameworks: Express
- Test Runner: node test/test.js
Architecture Rules
- Keep modules focused, decoupled, and single-responsibility.
- Colocate tests, types, and documentation with the corresponding modules.
Security & Input Sanitization
- Never hardcode API keys, secrets, credentials, or private tokens in source code or rules.
- Sanitize and validate all external inputs, request payloads, and query parameters.
Quality & Testing
- Ensure all new features, edge cases, and bug fixes have automated test coverage.
- Keep tests deterministic, isolated, and fast.
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.

windsurfrules is a cursor rule published in the GitHub repository mrzroot/agentforge (3 stars, last pushed 2d ago), licensed MIT. It adds 223 tokens to every session, about $0.0009 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 2026-10-09.
