What it does
Code Health is an agent skill from davepoon/buildwithclaude. Scans the codebase for dead code, tech debt, outdated dependencies, and code quality issues. Delegates to the Centinela (QA) agent.
Its SKILL.md is about 400 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, Dependency management and Technical debt. The repository describes itself as: A single hub to find Claude Skills, Agents, Commands, Hooks, Plugins, and Marketplace collections to extend Claude Code, Claude Desktop, Agent SDK and OpenClaw. The licence is MIT.
When your agent uses it
- Tasks that involve Code quality
- Tasks that involve Dependency management
- Tasks that involve Technical debt
Example prompts
- “Use the code-health skill to scan the codebase for dead code, tech debt, outdated dependencies, and code quality issues”
- “/code-health”
Workflow steps
8 steps, taken from the first numbered list in SKILL.md.
- Runs the SIGN IN checklist
- Scans for dead code (unused imports, variables, functions, commented-out blocks, unreachable code)
- Checks for outdated and vulnerable dependencies
- Detects code smells (long functions, deep nesting, duplication)
- Audits TODO/FIXME comments for issue references
- Runs the Scan Complete checklist (TIME OUT)
- Writes findings to docs/reviews/code-health-{date}.md
- Prepares findings handoff to Dev agent
What it can do on your machine
Read from SKILL.md and the folder at commit 10bfc43. 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
No scripts in the folder and no shell commands in SKILL.md.
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
Code Health loads about 398 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 184 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.

Code Health
Runs a comprehensive code health scan using the Centinela (QA) agent.
When to Use This Skill
- Periodic codebase hygiene check
- Before a release to ensure no dead code or unresolved debt
- After a large refactoring to verify cleanliness
- When onboarding to understand current code quality
What This Skill Does
- Runs the SIGN IN checklist
- Scans for dead code (unused imports, variables, functions, commented-out blocks, unreachable code)
- Checks for outdated and vulnerable dependencies
- Detects code smells (long functions, deep nesting, duplication)
- Audits TODO/FIXME comments for issue references
- Runs the Scan Complete checklist (TIME OUT)
- Writes findings to
docs/reviews/code-health-{date}.md - Prepares findings handoff to Dev agent
How to Use
Basic Usage
/code-healthExample
User: /code-health
Output: A code health report at docs/reviews/code-health-2026-02-23.md with:
- Dead code findings (verified, not false positives)
- Dependency status and vulnerabilities
- Code smell inventory
- TODO/FIXME audit
- Prioritized findings: Critical > Warning > Suggestion
Tips
- Scans all source directories, not just
src/— includestests/and config files - Previous scan findings are compared to track recurring issues
- Findings are verified to avoid false positives from dynamic imports or plugins
