Lint and Validate Skill

MANDATORY: Run appropriate validation tools after EVERY code change. Do not finish a task until the code is error-free.

Procedures by Ecosystem

Node.js / TypeScript

Lint/Fix:
```
npm run lint
```
or
```
npx eslint "path" --fix
```
Types:
```
npx tsc --noEmit
```
Security:
```
npm audit --audit-level=high
```

Python

Linter (Ruff):
```
ruff check "path" --fix
```
(Fast & Modern)
Security (Bandit):
```
bandit -r "path" -ll
```
Types (MyPy):
```
mypy "path"
```

The Quality Loop

Write/Edit Code
Run Audit:
```
npm run lint && npx tsc --noEmit
```
Analyze Report: Check the "FINAL AUDIT REPORT" section.
Fix & Repeat: Submitting code with "FINAL AUDIT" failures is NOT allowed.

Error Handling

If
```
lint
```
fails: Fix the style or syntax issues immediately.
If
```
tsc
```
fails: Correct type mismatches before proceeding.
If no tool is configured: Check the project root for
```
.eslintrc
```
,
```
tsconfig.json
```
,
```
pyproject.toml
```
and suggest creating one.

Strict Rule: No code should be committed or reported as "done" without passing these checks.
