superlint

superlint is a skill for Claude Code, Codex from mgechev/skillgrade. It costs 0 tokens per session (219 once invoked), scanned A, original, MIT.

A workflow for checking and correcting code with an internal tool called SuperLint. It produces a check report, applies fixes, and verifies the result.

In plain words
What is it for?
Use it to inspect a file, apply SuperLint corrections, and confirm that verification has passed.
Why use it?
It provides the required sequence for resolving code-quality issues when ordinary ESLint or Prettier commands are not the approved process.

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

superlint 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 4d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (app.js, fixtures/app.js), 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

SuperLint Proprietary Workflow

This skill describes the mandatory standard operating procedure for using our internal SuperLint tool. Use this when tasks require fixing code quality issues according to corporate standards.

1. Description

SuperLint is a multi-stage validation tool. Standard ESLint or Prettier commands will NOT work.

2. Mandatory Workflow

To fix a file using SuperLint, you MUST follow these steps in order:

  1. Check: Run superlint check to generate a report.
  2. Fix: Run superlint fix --target <filename> to apply automated corrections.
  3. Verify: Run superlint verify to finalize the changes and generate the .superlint-passed metadata file.

[!IMPORTANT] The verifier will fail if .superlint-passed is missing, even if the code looks correct.

3. Examples

# Correct usage for app.js
superlint check
superlint fix --target app.js
superlint verify
Files

What ships with it

5 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.
