Cursor rule for Cursor

Written for Cursor: installed under .cursor/. Also seen: mentions AGENTS.md.

This is aporb/agentic-os's own configuration. It tells Cursor how to work on agentic-os itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agentic-os configures →

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 2mo 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

Read AGENTS.md first. It has the full developer-facing instructions for this Next.js codebase.

This repo is the open-source Agentic OS Console — a Next.js 15 web app that runs locally and talks to Hermes Agent. Audience for the product itself is solo founders; this file is for AI assistants helping develop the codebase.

Strict voice rules across all code, copy, comments, and skill files:

  • USE: leverage, own, compete, coordination overhead, second brain, pipeline, runway
  • AVOID: productivity, efficient, automate, seamless, AI workforce, AI company, founding cohort, em-dash abuse, hedging language

Don't:

  • Add a chat surface to the Next.js app (Hermes already has chat)
  • Use paid search APIs (Tavily, Perplexity, Bing) — use lib/search.ts (ddgr → gogcli → browser)
  • Add paid-tier feature flags or upsell prompts
  • Push to git remote without user consent
  • Anthropomorphize with named character agents (persona system is user-customizable)

See AGENTS.md for full conventions.

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.
