lithium-kb: Cursor rule for Cursor

.cursorrules

cursorrules is a cursor rule for Cursor from liulinnuha/lithium-kb. It costs 147 tokens per session, scanned A, original, MIT.

A set of rules for a lightweight project knowledge base stored in an .agent-kb folder, with a visual graph and MCP support for coding agents.

In plain words
What is it for?
Use it to guide repository navigation, record task and bug notes, and maintain project memory for tools such as Claude, Codex, Cursor, or Windsurf.
Why use it?
It gives agents a fixed way to read project knowledge, track tasks and bugs, and keep that knowledge synchronized.

Cursor rule for Cursor

Written for Cursor: installed under .cursor/.

This is liulinnuha/lithium-kb's own configuration. It tells Cursor how to work on lithium-kb 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 lithium-kb 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 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

Agent Navigation & Memory Directives

  1. Zero Blind Crawling: Before crawling files across the repository, read .agent-kb/ or PROJECT_KB.md.
  2. Mandatory Task & Bug Tracking:
    • For every task, UI refactor, or feature assigned, create/update .agent-kb/tasks/.md.
    • For every resolved bug or diagnostic fix, document root cause and solution in .agent-kb/debug/.md.
  3. Keep Memory Synced: Run 'npx @liulinnuha/lithium-kb' after updating .agent-kb/ docs.
  4. Deterministic Output: Do not emit dynamic timestamps or session headers in knowledge markdown files.

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.
