knip-deadcode

knip-deadcode is a skill for Claude Code, Codex from pproenca/dot-skills. It costs 61 tokens per session (1,829 once invoked), scanned A, original, MIT.

A best-practices guide for Knip, a tool that finds unused code and dependencies in JavaScript and TypeScript projects. It covers configuration, workspaces, exports, dependency analysis, CI checks, cleanup, and performance.

In plain words
What is it for?
Use it to configure Knip, inspect unused exports and dependencies, check monorepos—a repository containing multiple related projects—in CI, and plan cleanup work.
Why use it?
It helps identify code that can be removed while reducing false results caused by incorrect entry points or project configuration.

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-deadcode 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 3d 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.

Community Knip Dead Code Detection Best Practices

Comprehensive guide for detecting and removing dead code in JavaScript and TypeScript projects using Knip. Contains 43 rules across 8 categories, prioritized by impact to guide configuration, CI integration, and cleanup workflows.

When to Apply

Reference these guidelines when:

  • Configuring Knip for a new project or monorepo
  • Investigating false positives or false negatives
  • Setting up CI pipelines to prevent dead code regressions
  • Using auto-fix to clean up unused code
  • Optimizing Knip performance for large codebases

Rule Categories by Priority

Priority Category Impact Prefix
1 Configuration Foundations CRITICAL config-
2 Entry Point Strategy CRITICAL entry-
3 Workspace & Monorepo HIGH workspace-
4 Dependency Analysis HIGH deps-
5 Export Detection MEDIUM-HIGH exports-
6 CI Integration MEDIUM ci-
7 Auto-Fix Workflow MEDIUM fix-
8 Performance Optimization LOW-MEDIUM perf-

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.
