Automatic quality control, linting, and static analysis procedures.

  • Works in 3 steps: Lint/Fix: npm run lint or npx eslint… → Types: npx tsc --noEmit → Security: npm audit --audit-level=high
  • Static analysis
  • SKILL.md covers The Quality Loop, Error Handling and Scripts
  • Runs Python scripts from its folder; calls npm, npx and python

What it does

Lint And Validate is an agent skill from xenitV1/Antigravity-Workflows. Automatic quality control, linting, and static analysis procedures. Use after every code modification to ensure syntax correctness and project standards. Triggers onKeywords: lint, format, check, validate, types, static analysis.

Its SKILL.md is about 430 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `scripts/lint_runner.py` and `scripts/type_coverage.py`).

It sits in Development, covering Linting and formatting and Static analysis and SAST. It works with Python. The licence is MIT.

When your agent uses it

  • Static analysis
  • Tasks that involve Linting and formatting
  • Tasks that involve Static analysis and SAST

Example prompts

  • “/lint-and-validate”

Requirements

  • Python 3
  • Node.js
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, Bash

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

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

What it can do on your machine

Read from SKILL.md and the folder at commit f0a1fa7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob
    • Grep
    • Bash

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • npm
    • npx
    • python
    • ruff
    • mypy

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm and npx, which can reach the network depending on how they are called.

    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

Lint And Validate loads about 432 tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 176 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~432

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Glob, Grep, Bash

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); the scripts in this folder are not scanned.

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.
