In plain words
What is it for?
Use it after code changes in Node.js, TypeScript, or Python projects to run the available checks and fix reported problems.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

lint-and-validate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/lint_runner.py, scripts/type_coverage.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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
  1. Lint/Fix: npm run lint or npx eslint "path" --fix
  2. Types: npx tsc --noEmit
  3. Security: npm audit --audit-level=high
Python
  1. Linter (Ruff): ruff check "path" --fix (Fast & Modern)
  2. Security (Bandit): bandit -r "path" -ll
  3. Types (MyPy): mypy "path"

The Quality Loop

  1. Write/Edit Code
  2. Run Audit: npm run lint && npx tsc --noEmit
  3. Analyze Report: Check the "FINAL AUDIT REPORT" section.
  4. 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.


Scripts

Script Purpose Command
scripts/lint_runner.py Unified lint check python scripts/lint_runner.py <project_path>
scripts/type_coverage.py Type coverage analysis python scripts/type_coverage.py <project_path>

When to Use

This skill is applicable to execute the workflow or actions described in the overview.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
