What it does
Remove Dead Code is an agent skill from qdhenry/Claude-Command-Suite. Safely identifies and removes dead code in TypeScript/JavaScript projects using multi-agent analysis with automatic backup branches. Use when cleaning up unused exports, orphaned files, dead imports, unreachable functions, or unused dependencies.
Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `references/agent-coordination.md`, `references/detection-patterns.md` and `workflows/remove-dead-code.md`).
It sits in Agent Workflows, covering Code simplification. It works with JavaScript and TypeScript. The repository describes itself as: Professional slash commands for Claude Code that provide structured workflows for software development tasks including code review, feature creation, security auditing, and…
When your agent uses it
- Cleaning up unused exports
- Unreachable functions
- Unused dependencies
Example prompts
- “/remove-dead-code”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Scan - Analyze codebase for dead code (read-only, produces report)
- Remove - Remove confirmed dead code (requires prior scan report)
- Validate - Verify removal didn't break anything (post-removal checks)
What it can do on your machine
Read from SKILL.md and the folder at commit e89b2f0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
tscnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Remove Dead Code loads about 986 tokens when it runs, and up to ~3.6k if it reads all its reference files. Until then it costs about 66 tokens; SKILL.md has 453 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 453 words (~986 tokens).
“Safety-first dead code removal. Every removal is protected by an automatic backup branch. Multi-agent analysis reduces false positives. No code is deleted without cross-validation.”
