debugging-standards

A code-checking rule for debugging and error handling in PHP, JavaScript, TypeScript, Vue, JSX, TSX, and Python projects.

In plain words
What is it for?
Use it to find statements such as console.log, print_r, and var_dump, and to review catch blocks for proper handling and useful logs.
Why use it?
It helps remove temporary debug output and catches empty error handlers that can hide failures.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 239 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

debugging-standards 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.

Ensures proper debugging practices and error handling.

Rule Details

  • Name: debugging_standards

  • Description: Enforce standards for debugging and error handling

Filters

  • file extension pattern: \\.(php|js|ts|vue|jsx|tsx|py)$

Enforcement Checks

  • Conditions:
    • pattern console\\.log\\(|print_r\\(|var_dump\\( – Replace debug statements with proper logging
    • pattern catch\\s*\\([^)]*\\)\\s*\\{\\s*\\} – Implement proper error handling in catch blocks

Suggestions

  • Guidance: Debugging Best Practices:
  • Address root causes, not symptoms
  • Add descriptive logging messages
  • Create isolated test functions
  • Implement comprehensive error handling
  • Use appropriate logging levels
  • Add context to error messages
  • Consider debugging tools integration

Metadata

  • Priority: high
  • Version: 1.1

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.

It costs nothing until one of its globs matches a file; then it loads 239 tokens. 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 2026-08-30.
