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 | $0.00539 | $0.00539 |
| Opus 5 | $0.00269 | $0.00269 |
| Sonnet 5 | $0.00108 | $0.00108 |
| Haiku 4.5 | $0.00054 | $0.00054 |
Grade A, and why
00-model-router 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Model Router
You have access to a model configuration system. When responding to user requests, identify the task type and recommend the appropriate model from the active profile.
Active Profile Reference
The current model profile is defined in .cursor/model-profiles/current-profile.json. Read this file to determine which models are configured for each task type.
Task Type Detection
Analyze the user's request to identify the primary task type:
| Task Type | Trigger Keywords/Patterns |
|---|---|
| planning | "plan", "design", "architect", "structure", "how should I", "what's the best approach" |
| reasoning | "why", "explain", "analyze", "debug", "what's happening", "understand" |
| refactor | "refactor", "clean up", "improve", "optimize", "restructure", "rename" |
| summarize | "summarize", "overview", "what does this do", "explain this code", "tl;dr" |
| long_context | Large file operations, multiple files, entire codebase questions |
| compliance | "review", "check", "validate", "security", "best practices", "standards" |
| creative | "create", "build", "new feature", "implement", "write", "generate" |
| draft | "quick", "draft", "sketch", "rough", "prototype", "poc" |
Response Format
When you detect a task type, include a model recommendation at the start of your response:
📍 Task: [task_type] → Recommended model: [model_name]
If the user is already using the recommended model, you can omit this notice.
Profile Awareness
- If the user mentions "quota", "rate limit", or "too expensive", suggest switching to the
fallbackorcost_minimizedprofile - If the user needs deep analysis or multi-file work, suggest the
completenessprofile - For batch operations, suggest
cost_minimizedprofile
Model Selection Guidance
When recommending a model switch, explain why:
- Speed: Some models are faster for quick iterations
- Depth: Some models provide more thorough analysis
- Cost: Some models are more cost-effective
- Context: Some models handle larger contexts better
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.

00-model-router is a cursor rule published in the GitHub repository jonafrank/cursor-multi-model-config (5 stars, last pushed 8mo ago), licensed MIT. It adds 539 tokens to every session, about $0.0027 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 2026-08-31.
