What it does
Code Quality is an agent skill from WrongStack/WrongStack. Find and remove unused code, ghost dependencies, unnecessary coupling and bundle waste with source-confirmed reachability. Use when cleaning exports or packages, reviewing Knip output or reducing dead code; use security-scanner for security findings and preserve public/dynamic entrypoints.
Its SKILL.md is about 760 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 and Vulnerability scanning. The repository describes itself as: An AI coding agent that reads your code, edits files, runs commands, and reasons through bugs — across a terminal REPL, a full-screen TUI, and a browser UI, while you keep your… The licence is MIT.
When your agent uses it
- Cleaning exports
- Reviewing Knip output
- Reducing dead code
- Use security-scanner for security findings and preserve public/dynamic entrypoints
Example prompts
- “/code-quality”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Inspect scripts, package exports, plugin registries, framework conventions,
- Separate internal unused code from public API: external consumers may not
- Verify every removal through import/call sites, dynamic use and relevant
- Fix configuration false positives narrowly; broad ignores hide later defects.
- Keep behavior changes separate from cleanup and preserve dirty work.
- Measure bundle/runtime savings against matched builds; deleted lines are
What it can do on your machine
Read from SKILL.md and the folder at commit a744bdc. 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
Links to these hosts (documentation or services it may open):
knip.devbiomejs.dev
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 Quality loads about 763 tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 295 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 Quality
Selection card
- Task: Measure dead code, unused dependencies and bundle waste. / TR: Ölü kod, kullanılmayan bağımlılık ve bundle israfını ölç.
- Start: Identify the scope and obtain an executable before-proof or review evidence.
- Finish: apply the acceptance checks below; report observed results and unresolved constraints.
Overview
Latest checked targets on 2026-10-09: Knip 6.41.0 and Biome 2.5.15. Use the repo's configured tools and verify migration deltas before upgrading. Static reachability findings are candidates until real consumers are checked.
Rules
- Inspect scripts, package exports, plugin registries, framework conventions, generated entrypoints and test/build configuration before declaring code unused.
- Separate internal unused code from public API: external consumers may not exist in this repository. Do not remove a public export merely because local references are absent.
- Verify every removal through import/call sites, dynamic use and relevant build output. Explain the evidence rather than dumping scanner results.
- Fix configuration false positives narrowly; broad ignores hide later defects.
- Keep behavior changes separate from cleanup and preserve dirty work.
- Measure bundle/runtime savings against matched builds; deleted lines are not proof of a smaller shipped artifact or faster execution.
Workflow
- Run the current quality command and record its candidate list/baseline.
- Group findings by entrypoint/config/dependency/export and confirm reachability.
- Remove a coherent set of confirmed unused items. Regenerate lockfiles through the package manager when dependencies change.
- Run affected type/build/tests and verify package export/consumer behavior.
- Rerun the quality scan; report resolved candidates, justified exclusions, unknown external usage and measured artifact changes where relevant.
Sources
Acceptance checks
- Run the selected analyzer against the scoped source, confirm findings and verify behavioral checks after cleanup.
Skills in scope
- codebase-navigation — actual consumers.
- refactor-planner — coupling and staged structural changes.
- testing — behavior preservation.
- tech-stack — dependency justification.
