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 | $0.00376 | $0.00376 |
| Opus 5.5 | $0.00150 | $0.00150 |
| Sonnet 5.5 | $0.00075 | $0.00075 |
| Haiku 4.5 | $0.00038 | $0.00038 |
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.
What it actually says
Project Rules & Context
MUST follow the rules in SCALA_SEMANTIC_RULES.md for working with Scala code. Mandatory, not optional.
Project Description & Startup Context
For detailed instructions, architecture, build/test commands, and conventions, please read CLAUDE.md on startup.
Quick Reference (from CLAUDE.md):
- Project: ScalaSemantic — MCP server for deep semantic analysis on Scala projects via SemanticDB.
- Stack: Scala 3.8.4, sbt 2.0.0, Scalameta 4.13.9, upickle 4.2.1, munit 1.2.3.
- Layout:
core/: Loads and indexes SemanticDB (SemanticIndex).analysis/: Result models and analyzer engine (depends oncore).mcp/: JSON-RPC server and stdio entrypoint (depends onanalysis).
- Core Commands:
- Compile:
sbt compile(regenerates SemanticDB) - Test:
sbt test(unforked tests run with cwd = repo root) - Pre-push check:
sbt prePush(clean, format, fix, test) - Run MCP server:
sbt "mcp/runMain com.github.mercurievv.scalasemantic.mcpServer <root>"
- Compile:
- Conventions:
- Follow Scala Code Rules in SCALA_SEMANTIC_RULES.md.
- Use Conventional Commit titles for squash merging PRs (
feat:,fix:,perf:).
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 MercurieVV/ScalaSemantic (22 stars, last pushed 8d ago), licensed MIT. It adds 376 tokens to every session, about $0.0015 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 2026-08-30.
