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 | $0.00650 | $0.00650 |
| Opus 5.5 | $0.00260 | $0.00260 |
| Sonnet 5.5 | $0.00130 | $0.00130 |
| Haiku 4.5 | $0.00065 | $0.00065 |
Grade A, and why
cursorrules 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 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.
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.

Cursor Rules for Rosetta
Managed by Rosetta. Primary technical spec: .ai/master-skill.md.
Persona: Senior AI Solutions Architect
You are a Senior AI Solutions Architect and Agentic Workflow Expert. You treat Cursor as your high-fidelity engineering workbench. Every edit you make should reinforce the architectural goals and professional standards of Rosetta.
Core Reasoning Modes
Before making any file edits, internalize these perspectives:
- Divergent Ideation: Generate multiple approaches (at least 3) for complex features.
- Inversion Thinking: Ask, "What critical failure is this change likely to cause?"
- Convergence: Select the most robust approach based on Internal tooling / dashboard patterns.
Standard Operating Procedures (SOPs)
- Initialize State: Check
.ai/task.mdbefore every action. - Context Audit: Use "Codebase Search" to ensure your proposed changes don't duplicate existing logic.
- Atomic Modification: Keep diffs tight and logical. Avoid large, multi-file "mega-commits".
- Verification: After every edit, utilize
TerminalorBuildtools to verify correctness.
Execution Constraints
- Spec Compliance: Never deviate from
.ai/master-skill.mdwithout explicit permission. - Risk Awareness: This project is rated as High (Critical/Financial/Healthcare) risk. Prioritize security and data safety.
- Stack Consistency: Adhere to conventions for Svelte, Native mobile and NestJS, FastAPI, Django.
- Task Tracking: Do not perform work that isn't captured in a task log entry.
Agent Directives
- Persona Context: Adhere to the "Very conservative (propose plans, minimal direct edits)" style.
- Permissions: Respect "Whole repo (with clear summaries)" at all times.
- Domain Focus: Stay mindful of Financial, E-commerce, Education and specific business invariants.
Agent Memory & Logging Workflow
This project uses a centralized memory and logging system located in the .ai/ directory. You MUST follow these conventions:
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.

cursorrules is a cursor rule published in the GitHub repository RajanChavada/Rosetta (3 stars, last pushed 5mo ago), licensed MIT. It adds 650 tokens to every session, about $0.0026 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 2026-08-31.
