check

A code-checking command that reviews source files for oversized files, long functions, and high decision complexity.

In plain words
What is it for?
Use it after coding changes to inspect TypeScript, JavaScript, Python, Go, Java, Ruby, Rust, PHP, or Swift files and find areas worth simplifying.
Why use it?
It gives you concrete warnings about code that may be becoming difficult to understand or maintain. You can check a file or directory against project settings or default limits.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

check 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 yesterday.

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.

Code Standards Check

Analyze $ARGUMENTS against code standards thresholds.

If no argument provided, analyze the current directory.

Analysis Process

Step 1: Load Settings

Read .claude/code-standards.local.md if it exists to get configured thresholds. If not found, use default thresholds:

  • File LOC: 400 (warning), 800 (critical)
  • Function LOC: 50 (warning), 80 (critical)
  • Complexity: 15 (warning), 20 (critical)

Step 2: Validate Target Path

If $ARGUMENTS is provided, verify the path exists:

If path does not exist:

Error: Path not found: `[path]`

Please verify the path exists. Use `/code-standards:check .` to analyze current directory.

If path exists but no source files found in directory:

No analyzable source files found in `[path]`

Supported: *.ts, *.tsx, *.js, *.jsx, *.py, *.go, *.java, *.rb
Excluded: node_modules, vendor, .git, dist, build

Step 3: Identify Target Files

If $ARGUMENTS is a single file, analyze that file. If $ARGUMENTS is a directory, find all source files:

  • TypeScript/JavaScript: *.ts, *.tsx, *.js, *.jsx
  • Python: *.py
  • Go: *.go
  • Java: *.java
  • Ruby: *.rb
  • Rust: *.rs
  • PHP: *.php
  • Swift: *.swift
  • Kotlin: *.kt
  • C#: *.cs

Exclude common directories: node_modules, vendor, .git, dist, build, __pycache__

Step 4: Analyze Each File

For each file:

  1. Count lines of code (exclude blank lines and comments where possible)
  2. Identify functions/methods and their line counts
  3. Estimate cyclomatic complexity based on:
    • if, else, elif, else if statements
    • for, while, loop iterations
    • case, when, switch branches
    • &&, || logical operators
    • catch, except, rescue exception handlers
    • Ternary operators ? :

Step 5: Report Violations

Output a structured markdown table:

## Code Standards Report

**Target:** $ARGUMENTS
**Files analyzed:** [count]
**Violations found:** [count]

### Violations

| File | Issue | Severity | Line | Suggestion |
|------|-------|----------|------|------------|
| `src/service.ts` | File exceeds 600 LOC (742) | Warning | - | Split by domain responsibility |
| `src/service.ts:45` | Function `processOrder` exceeds 80 LOC (112) | Critical | 45-157 | Extract helper functions |
| `src/utils.ts:89` | Complexity >15 in `handleRequest` (18) | Warning | 89 | Simplify conditionals or extract |

### Summary

- **Critical:** [count] issues (must fix)
- **Warning:** [count] issues (should address)
- **Info:** [count] notes (consider)

### Recommendations

[Based on violations, provide 2-3 specific refactoring suggestions]

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.

check is a command published in the GitHub repository hculap/better-code (2 stars, last pushed 7mo ago), licensed MIT. It adds 6 tokens to every session and 1,186 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
