cursor-rules CLAUDE.md

A set of written rules for the Cursor Rules mirror project, covering its design principles, communication style, coding standards, security practices, and response formats.

In plain words
What is it for?
Developing the project with its required Python and FastAPI conventions, testing expectations, secure handling of inputs, and output formats.
Why use it?
It helps an agent produce work that matches the project’s technical and privacy requirements.

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade B, and why

cursor-rules CLAUDE.md scanned grade B with 1 finding 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 2d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- May run bash/python snippets directly (no sudo without explicit permission)

AI Assistant Rules for The Mirror Project

Core Philosophy

You are assisting with The Mirror Project - a local-first, privacy-respecting AI workspace that unifies LLMs, personal health & context streams, and autonomous agents. Always prioritize:

  • Information density and engineering precision
  • Privacy and local-first architecture
  • Practical, working solutions over theoretical discussions

Communication Style

  • Be information-dense and engineering-precise; avoid fluff
  • Default to "you can do this" coaching tone
  • Ask clarifying questions ONLY when ambiguity blocks action
  • Prefer primary sources and official documentation; always cite links

Code Standards

  • Language: Python 3.11+ with type hints
  • Framework: FastAPI with Pydantic v2 for APIs
  • Style: Well-commented, runnable code with minimal external dependencies
  • Testing: Maintain 80%+ coverage with descriptive test names
  • Security: Never commit secrets, validate all inputs, use secure defaults

Output Formats

  • Code: Properly formatted with comments, ready to run
  • Tasks: Numbered checklists or YAML/JSON specs ready for agents
  • Documentation: Markdown with clear heading hierarchy and links
  • Diagrams: Mermaid for architecture, tables for comparisons

Technology Stack

Core

  • Python 3.11, FastAPI, Pydantic v2, Poetry/venv
  • PostgreSQL + TimescaleDB, Redis, Docker
  • GitHub Actions for CI/CD

ML/LLM

  • HuggingFace (transformers, accelerate)
  • Diffusion-based LLaDA-8B
  • Vector stores (Chroma), RAG implementations

Infrastructure

  • Kubernetes-lite (k3d), Prometheus + Grafana
  • Pulumi (TypeScript) for IaC
  • Git-secrets pre-commit hooks

Project-Specific Context

  • Building local-first health data integration (WHOOP, Oura, Tomorrow.io)
  • Implementing FastAPI/OpenAI-style endpoints
  • Creating Grafana dashboards for visualization
  • Ensuring GitHub Actions CI/CD with act-local parity

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.

cursor-rules CLAUDE.md is an instructions file published in the GitHub repository hamzaamjad/cursor-rules (2 stars, last pushed 1y ago), licensed MIT. It adds 688 tokens to every session, about $0.0034 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
