dead-code

A code-cleanup command that finds code the project no longer uses, including imports, exports, files, and dependencies. It can report findings or prepare removals for approval.

In plain words
What is it for?
Use it to inspect JavaScript, TypeScript, or Python projects for unused code. It can detect possible dead code without changes or help clean up confirmed findings.
Why use it?
Unused code makes projects harder to understand and maintain, and unused dependencies can add unnecessary maintenance and risk. Automated checks can also flag code that is actually used, so findings are verified first.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

dead-code 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.

Dead Code Detection

Analyze the project for dead code using automated tools with agent verification.

Mode

$ARGUMENTS

  • detect (default): Find and report dead code, no modifications
  • cleanup: Find dead code, then offer to remove after user approval

Tools Used

  • JavaScript/TypeScript: knip (npx knip)
  • Python: deadcode (pip install deadcode)

Project type is auto-detected from package.json, tsconfig.json, requirements.txt, or pyproject.toml.

IMPORTANT: False Positive Handling

Dead code tools return many false positives. The agent MUST verify each finding before reporting:

Verify Before Reporting

For each flagged item:

  1. Read the flagged code to understand its context
  2. Check for dynamic references: import(variable), require(variable), reflection
  3. Check framework patterns: React components, decorators, middleware
  4. Check re-exports: Is this in an index.ts barrel file for public API?
  5. Check entry points: CLI scripts, serverless handlers, workers

Common False Positives to Filter

  • Dynamic imports: import(modulePath), require(variableName)
  • React/Vue components used in JSX/templates
  • Decorated classes (Angular, NestJS, Python decorators)
  • Re-exports for public API in index files
  • Entry points configured outside standard patterns
  • Test utilities only used in test files
  • CLI scripts or serverless handlers

Workflow

  1. Invoke the dead-code-cleanup agent to run detection and verification:
    • The agent runs the detection tool via "${CLAUDE_PLUGIN_ROOT}"/scripts/dead-code-detect.sh
    • It parses findings into categories and verifies each item (reads code, filters false positives)
    • It returns a verified report plus a proposed cleanup plan grouped by confidence (safe / needs-review)
  2. Present the returned report and plan to the user
  3. If cleanup mode: use AskUserQuestion to ask which groups to remove
  4. Apply only the approved removals

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.

dead-code is a command published in the GitHub repository jeffrigby/somepulp-agents (7 stars, last pushed 1mo ago), licensed MIT. It adds 16 tokens to every session and 753 once invoked, about $0.0001 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.
