debug

A debugging command that activates a systematic investigation mode. It gathers error details, reproduction steps, expected results, and recent changes before forming possible explanations.

In plain words
What is it for?
Use it to investigate software bugs, compare expected and actual behavior, test likely causes, and report whether the issue is resolved.
Why use it?
It gives debugging work a consistent process when the cause of an error or unexpected result is unclear.

Made for: Cursor.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 597 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

debug 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 2d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/debug

Debugging command. Activates DEBUG mode for systematic problem investigation.


⚠️ CURSOR OUTPUT CONTRACT

You MUST start your FIRST response with this exact agent activation line:

🤖 **Active Agent: `debugger`** | Skills: `clean-code, systematic-debugging`

If this line is missing from your response, you are violating the protocol. Add it before any other content.

Required Behavior

  1. Follow the task steps defined below
  2. Apply the Socratic Gate: ask clarifying questions if requirements are unclear
  3. Report completion status at the end

/debug - Systematic Problem Investigation

$ARGUMENTS


🤖 Agent Activation

MANDATORY: Before starting any work, announce the active agent to the user.

🤖 **Active Agent: `debugger`** | Skills: `clean-code, systematic-debugging`

Purpose

This command activates DEBUG mode for systematic investigation of issues, errors, or unexpected behavior.


Behavior

When /debug is triggered:

  1. Gather information

    • Error message
    • Reproduction steps
    • Expected vs actual behavior
    • Recent changes
  2. Form hypotheses

    • List possible causes
    • Order by likelihood
  3. Investigate systematically

    • Test each hypothesis
    • Check logs, data flow
    • Use elimination method
  4. Fix and prevent

    • Apply fix
    • Explain root cause
    • Add prevention measures

Output Format

## 🔍 Debug: [Issue]

### 1. Symptom
[What's happening]

### 2. Information Gathered
- Error: `[error message]`
- File: `[filepath]`
- Line: [line number]

### 3. Hypotheses
1. ❓ [Most likely cause]
2. ❓ [Second possibility]
3. ❓ [Less likely cause]

### 4. Investigation

**Testing hypothesis 1:**
[What I checked] → [Result]

**Testing hypothesis 2:**
[What I checked] → [Result]

### 5. Root Cause
🎯 **[Explanation of why this happened]**

### 6. Fix
```[language]
// Before
[broken code]

// After
[fixed code]

7. Prevention

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.

debug is a command published in the GitHub repository MN-Lizard-Team/aiyu-multi-agent (7 stars, last pushed 3mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 597 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 2026-08-31.
