debugger

debugger is a command for Claude Code from ruvnet/RuView. It costs 0 tokens per session (284 once invoked), scanned A, original, MIT.

A structured debugging command for finding and fixing software problems by reproducing them, tracing their causes, and checking the fix.

In plain words
What is it for?
Use it to investigate error logs, stack traces, memory leaks, slow code, variable values, call paths, and whether a fix resolves the issue.
Why use it?
It turns an unclear error into a tracked investigation, helping separate the underlying cause from its visible symptoms.

About the project

RuView is a WiFi sensing platform that uses disturbances in radio signals, captured by low-cost ESP32 sensors, to detect presence, movement, breathing, and heart rate without cameras or wearables. It is intended for spatial monitoring and smart-home integrations. The catalogue add-ons support workflows for operating and integrating RuView.

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

debugger 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 1mo 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.

What it actually says

SPARC Debugger Mode

Purpose

Systematic debugging with TodoWrite and Memory integration.

Activation

Option 1: Using MCP Tools (Preferred in Claude Code)

mcp__claude-flow__sparc_mode {
  mode: "debugger",
  task_description: "fix authentication issues",
  options: {
    verbose: true,
    trace: true
  }
}

Option 2: Using NPX CLI (Fallback when MCP not available)

# Use when running from terminal or MCP tools unavailable
npx claude-flow sparc run debugger "fix authentication issues"

# For alpha features
npx claude-flow@alpha sparc run debugger "fix authentication issues"

Option 3: Local Installation

# If claude-flow is installed locally
./claude-flow sparc run debugger "fix authentication issues"

Core Capabilities

  • Issue reproduction
  • Root cause analysis
  • Stack trace analysis
  • Memory leak detection
  • Performance bottleneck identification

Debugging Workflow

  1. Create debugging plan with TodoWrite
  2. Systematic issue investigation
  3. Store findings in Memory
  4. Track fix progress
  5. Verify resolution

Tools Integration

  • Error log analysis
  • Breakpoint simulation
  • Variable inspection
  • Call stack tracing
  • Memory profiling
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.

debugger is a command published in the GitHub repository ruvnet/RuView (98,212 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 284 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.
