knip

knip is a cursor rule for Cursor from louisbrulenaudet/monorepo-template. It costs 0 tokens per session (997 once invoked), scanned A, original, Apache-2.0.

A policy for Knip, a tool that finds unused files, exports, and dependencies in JavaScript and TypeScript projects. It explains why the repository has specific exceptions and how both normal and production checks must pass.

In plain words
What is it for?
Use it when changing Knip configuration, adding dependencies or exports, or investigating unused-code failures in workspace packages.
Why use it?
It catches dead code and stale configuration without incorrectly flagging development-only tools or test support files.

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

knip 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 5d 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.

Knip Configuration & Policy

Root knip.jsonc is intentionally comment-free; every override's rationale lives here. Official docs: configuration, production mode, configuring project files.

Root options

Option Why
includeEntryExports: true Every workspace is "private": true, so entry/barrel files (packages/*/src/index.ts) get full unused-export auditing
treatConfigHintsAsErrors: true Stale or redundant overrides (e.g. an entry a plugin now provides) fail the gate instead of rotting silently

Workspace overrides

apps/front-*

  • ignoreDependencies entries are suffixed ! = production mode only:
    • @tanstack/*-devtools - imported by AppDevtools.tsx, which is lazy-loaded behind import.meta.env.DEV; production builds never statically include them, but Knip's static graph cannot evaluate that conditional.
    • tailwindcss - build-time dependency consumed through @tailwindcss/vite + the @import "tailwindcss" in src/index.css.
  • project replicates the default glob plus production-only negations ("!tests/helpers/**!", "!vitest.setup.ts!") so test infrastructure - helpers like tests/helpers/session-storage-mock.ts and the setupFiles entry vitest.setup.ts - is never flagged as unused shipped code. Do not use ignore or ignoreFiles for this - ignoreFiles rejects the production-only ! suffix here.

apps/!(front-*)

  • Every app that is not the SPA - worker-* today, queue-* / webhook-* / mcp-* when they land. A negation rather than a list of prefixes because treatConfigHintsAsErrors: true makes a workspace key matching nothing a hard error, so unused prefixes cannot be declared ahead of time.
  • ignoreDependencies: ["cloudflare"] - import ... from "cloudflare:workers" in Workers-pool tests is a runtime protocol specifier resolving to no npm package.

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.
