aica: Cursor rule for Cursor

.cursorrules

cursorrules is a cursor rule for Cursor from dotneet/aica. It costs 133 tokens per session, scanned A, original, Apache-2.0.

A set of Cursor rules describing this project's technology stack, runtime, and commands for running TypeScript files and tests.

In plain words
What is it for?
It is for telling Cursor how to run TypeScript files, run all tests, run one test file, and write tests with Bun's Jest-compatible API.
Why use it?
It gives Cursor project-specific instructions so it uses Bun and the correct test commands.

Cursor rule for Cursor

Written for Cursor: installed under .cursor/.

This is dotneet/aica's own configuration. It tells Cursor how to work on aica 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 aica 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 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.
