Music on; nonsense off.

My other skills (result-not-throw, vertical-slices, node-native-tests, single-tool-per-job) assume the repo has a few things wired up: pnpm via corepack, a Biome config, a posture on the test runner, a CONTEXT.md glossary, and a docs/adr/ directory. This skill scaffolds those once.

Run me before the others. After I'm done, the other skills have something to point at.

Phase 1 — Detect

Read the repo first. Don't assume.

• package.json exists? Check packageManager field.
• Is there an existing pnpm-workspace.yaml, pnpm-lock.yaml, or lerna.json?
• Is there an existing biome.json or biome.jsonc? Capture its $schema version (1.9.x = legacy, 2.x = new).
• Is there an existing test setup? Look for jest.config.*, vitest.config.*, node:test imports, borp in dependencies.
• Does CONTEXT.md exist at the root? Does docs/adr/ exist?
• What package manager is in the lockfile (pnpm-lock.yaml, package-lock.json, yarn.lock)?
