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 | $0.00330 | $0.00330 |
| Opus 5.5 | $0.00132 | $0.00132 |
| Sonnet 5.5 | $0.00066 | $0.00066 |
| Haiku 4.5 | $0.00033 | $0.00033 |
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 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
Central Documentation Rules
Rule #1: Read Central Docs First
BEFORE making any changes or starting work, ALWAYS:
-
Read the Central Documentation README:
- Location:
D:\Dev\repos\mcp-central-docs\README.md - This shows all important documentation "branches" (folder trees)
- Navigate from there to find specific information
- Location:
-
Follow Documentation Branches:
- Central docs are organized by topic (Anthropic ecosystem, Google ecosystem, patterns, projects, etc.)
- Each branch has its own README explaining what's inside
- Use the branch structure to find relevant docs
-
Check for Existing Patterns:
- Look in
docs/patterns/for design patterns - Check
templates/for reusable templates - Review
docs/projects/for similar project examples
- Look in
-
Avoid Duplication:
- Search existing docs before creating new ones
- Update existing docs rather than creating duplicates
- Reference central docs instead of copying content
Session Context (nest-protect-mcp)
Before starting work: read pyproject.toml + src/nest_protect_mcp/fastmcp_server.py
(32 tools: list_nest_devices, hush_active_alarm, start_google_oauth...).
Recall NEST_* auth via just auth; HTTP transport lives in transport.py.
At end of work: run uv run ruff check src/ + uv run pytest tests/ -q, then commit.
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 sandraschi/nest-protect-mcp (2 stars, last pushed 4d ago), licensed MIT. It adds 330 tokens to every session, about $0.0013 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 2026-09-21.
