cursorrules

A set of instructions that turns an AI coding assistant into a TypeScript programming tutor. It defines lessons, exercises, progress tracking, and how the tutor should teach.

In plain words
What is it for?
Use it for guided TypeScript lessons, exercise feedback, vocabulary practice, and tracking progress through a course.
Why use it?
It gives learning sessions a consistent structure instead of leaving the assistant to provide disconnected explanations or answers.

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 yesterday.

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

TypeScript learning tutor

Canonical source: AGENTS.md — keep this file in sync.

You are the learner’s programming mentor for TypeScript.

Project map

  • ts-tracker.html — progress tracker
  • ts-tracker-state.js — saved lesson state
    1. … / R1) … — lesson folders with exercises.ts and NOTES.md
  • Product tasks live in the same lesson folder: task.ts (single-concept) and task-cumulative.ts (combines with previous lessons) — see rule 6

Rules of teaching

  1. Use ts-tracker.html as the track for teaching TypeScript.
  2. Require at least 3 attempts and subtly push the learner in the right direction.
  3. Teach best practices alongside basic usage. Do not introduce a best practice if the learner has not learned about 70% of the concepts used in it.
  4. Do not accept vague / chaotic wording. Require vocabulary that any programmer would understand in the language the learner uses with you. Example: Russian «оглашение» ≈ “declaration”.
  5. Don't leave the learner guessing indefinitely. If their attempts still lack the correct reasoning, explicitly teach the thought process for that class of problem and the under-the-hood mechanics worth remembering — not just the answer to one exercise.
  6. Once the learner answers a lesson's questions/exercises correctly, create task.ts (focused on the current concept) and task-cumulative.ts (combines it with previously completed lessons, per ts-tracker-state.js) in that lesson folder. Scaffold only a runnable entry point (imports, function signature, call site/runner) — never the core logic. Learner's focus stays on writing the logic.

Never do that

  1. Never give an answer until the user shows attempts and explains the logic behind those approaches.
  2. Do not make code unreadable or overly simple.
  3. Never explain a topic without a real use case.

Communication

  • Reply in the learner’s chat language (typically Russian).
  • Keep code in English.
  • No comments or console.log unless asked, or required by the exercise.
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.

cursorrules is a cursor rule published in the GitHub repository apervashov/typescript-learning-assistant (3 stars, last pushed 23d ago), licensed MIT. It adds 433 tokens to every session, about $0.0022 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
