At a glance
Runs a user-invoked, swarm-style audit of a whole codebase for SOLID and DRY violations, code smells, complexity, dead code and pattern consistency, with a prioritized report.

- Running a periodic health check across an entire codebase
- SKILL.md covers MCP Tools, Audit Workflow, Parallel Analysis Pattern and Audit Dimensions, plus 3 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
This skill launches parallel worker-reviewer agents, one per audit dimension, to review a codebase as a whole rather than one diff at a time. The dimensions are SOLID and DRY violations, checked against the project's own code-quality rules file and, for duplication, with AST-based tools like jscpd rather than plain grep patterns; code smells from Fowler's catalog such as long methods, large classes, feature envy, data clumps and primitive obsession; and pattern consistency across error handling, async usage, naming, imports and type versus interface usage.
It also covers cyclomatic complexity and function or class size, measured with language-appropriate tools such as radon for Python, gocyclo for Go or cargo-geiger for Rust, and dead code, found with tools like knip or depcheck for TypeScript, vulture for Python, or cargo-udeps for Rust, verified before deletion because dynamic imports can produce false positives.
A scope-adherence dimension reapplies a sibling skill's review lens, normally used per diff, across the whole codebase instead, watching for unrequested refactors, drive-by edits and orphaned dead code, deferring to that sibling skill for the full perspective rather than restating it; workers can also use a sequential-thinking MCP tool for complex trade-off analysis. The result is a prioritized findings report with remediation suggestions, assembled into a single Codebase Health Report.
When your agent uses it
- Running a periodic health check across an entire codebase
- Finding SOLID and DRY violations beyond what a single PR diff would show
- Locating dead code and unused exports safely, with false positives checked
- Auditing consistency of error handling, naming and async patterns project-wide
Example prompts
- “Run a full codebase health audit and give me a prioritized report.”
- “Check this codebase for DRY violations using an AST-based duplication tool, not just grep.”
- “Find dead code and unused exports, but verify before suggesting deletion.”
- “Audit naming and async pattern consistency across the whole project.”
Requirements
- Language-appropriate static analysis tools such as jscpd, radon, gocyclo or cargo-geiger
- A multi-agent runner able to launch parallel worker-reviewer agents
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Swarm — Launch parallel worker-reviewer agents for each audit dimension
- SOLID — Audit for principle violations
- DRY — Detect knowledge duplication
- Smells — Identify code smells from Fowler's catalog
- Consistency — Check pattern consistency across codebase
- Report — Generate prioritized findings with remediation
What it can do on your machine
Read from SKILL.md and the folder at commit 6436a20. 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 (its code samples are markdown).
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
Codebase Health Auditor loads about 980 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 358 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 358 words (~980 tokens).
“Regular codebase review for Clean Code, SOLID, DRY principles and consistency.”
