What it does
Dead Code Cleanup is an agent skill from calimero-network/core. Detects and removes dead code introduced by AI agents. Analyzes codebase for unused functions, variables, imports, and types; verifies no references (including indirect, dynamic, or runtime); reports with file paths and line numbers; optionally generates safe patches. Use when cleaning up after AI-generated code, removing unused code, or when the user asks for dead code detection, unused code removal, or code quality cleanup.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Code quality. The repository describes itself as: Calimero - Peer-to-peer application platform with local-first governance, CRDT state sync, and WASM execution.
When your agent uses it
- Cleaning up after AI-generated code
- Removing unused code
- The user asks for dead code detection
- Unused code removal
Example prompts
- “Use the dead-code-cleanup skill to detect and removes dead code introduced by AI agents. An agent skill from calimero-network/core”
- “/dead-code-cleanup”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Identifying dead code candidates
- Verification (required before removal)
- Exclusions (do not remove unless user confirms)
- Report format
- Safe removal and patches
What it can do on your machine
Read from SKILL.md and the folder at commit 379600b. 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:
cargorg
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Dead Code Cleanup loads about 1.5k tokens when it runs. Until then it costs about 112 tokens; SKILL.md has 598 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 598 words (~1,509 tokens).
“Remove unused code introduced during development while avoiding functional regressions. Always verify that code is truly unused before suggesting removal.”
