cursorrules

Project instructions for working with Noetix Bumi humanoid specifications, open-source references, virtual twins, and an optional robot bridge. A virtual twin is a software model of a physical robot.

In plain words
What is it for?
Reviewing Bumi specifications and open-source links, checking a connected robot bridge, and handling read-only project queries safely.
Why use it?
It gives the agent required preparation and cleanup guidance before and after work on this robot-related project.

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 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 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.

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

Session Context (Bumi-MCP)

You have access to Noetix Bumi humanoid specs, OSS links, virtual-twin guidance, and optional robot bridge.

Before starting work:

  1. Check Bumi specs
  2. Review OSS links and references
  3. Check bridge status if robot is connected

At end of work:

  • No cleanup needed (read-only queries are safe)
Changes

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.
