launch is a cursor rule for Cursor from YosefHayim/launch-store. It costs 300 tokens per session, scanned A, original, MIT.

A set of always-on working rules for the launch CLI codebase, a Node.js and TypeScript command-line application for app-store work. It explains where code belongs, how changes should be tested, and which checks must pass.

In plain words
What is it for?
Use it when modifying launch commands, core logic, store backends, documentation, tests, or build processes in that repository.
Why use it?
It keeps contributions consistent and prevents misplaced files, undocumented command changes, missing tests, and accidental exposure of secrets.

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

launch 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 12d 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

You are working on launch-store (the launch CLI), not using it. The canonical working rules live in AGENTS.md - read it first.

  • One Node ESM / TypeScript package. src/cli is thin Commander wiring, src/core is purpose-grouped domain code, src/providers are swappable backends, src/apple and src/google are store API mirrors, and src/testkit holds shared fakes/layers.
  • Do not create flat src/core/*.ts files. Put new core work under the owning purpose folder such as build/, config/, credentials/, release/, store/, services/, terminal/, or types/.
  • Before calling a change done, run pnpm typecheck && pnpm lint && pnpm lint:style && pnpm docs:check && pnpm test && pnpm build (the generated docs + these rules are gated).
  • Keep it KISS / YAGNI / DRY: extend the nearest sibling file rather than inventing a new file, util, or abstraction. Add a test (*.test.ts) beside any new logic.
  • Never log, write, or commit secrets; ~/.launch holds non-secret paths and ids only.
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.
