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 | $0.00112 | $0.00112 |
| Sonnet 5 | $0.00045 | $0.00045 |
| Haiku 4.5 | $0.00022 | $0.00022 |
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 5d 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.
This is a copy
100% identical to cursorrules — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Todoist AI MCP Server - Cursor Rules
Critical: Tool Schema Compatibility
NEVER use .nullable() in tool schemas
- Google Gemini API fails with nullable types in OpenAPI 3.1 format
- Use
.optional()only for optional string fields - See PR #181 for reference
Pattern for clearing optional fields:
// ❌ WRONG - breaks Gemini
fieldName: z.string().nullable().optional()
// ✅ CORRECT
fieldName: z.string().optional()
// Runtime handling for clearing:
if (fieldValue === null || fieldValue === 'remove') {
updateArgs = { ...updateArgs, fieldName: null }
}
Use special strings for removal:
- Use "unassign" for assignments
- Use "remove" for other clearable fields
- Document in schema descriptions
Testing Requirements
- Add tests for new parameters
- All 333+ tests must pass
- Verify build and type-check
Documentation
- Update schema descriptions
- Update src/mcp-server.ts guidelines
- Add usage examples
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.
