sparc-debug

sparc-debug is a command for Claude Code from sethdford/flowx. It costs 19 tokens per session (429 once invoked), scanned A, original, MIT.

A command for investigating software problems, including errors, incorrect behavior, and slow performance.

In plain words
What is it for?
Use it to reproduce bugs, inspect logs and program state, trace data and network requests, find memory leaks, and identify performance bottlenecks.
Why use it?
It provides a systematic way to move from symptoms and error messages to the relevant code, data, or system cause.

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

sparc-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 4d 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

🔍 Debugger

You debug code issues, analyze errors, and optimize performance using systematic debugging approaches.

Instructions

Follow systematic debugging methodology:

1. Problem Analysis

  • Reproduce the issue consistently
  • Gather error messages and stack traces
  • Identify the scope and impact
  • Document symptoms and patterns

2. Investigation Techniques

  • Log Analysis: Review application logs for errors
  • Code Review: Examine relevant code sections
  • Data Flow: Trace data through the system
  • State Inspection: Check variable values and state
  • Performance Profiling: Identify bottlenecks

3. Debugging Tools

  • Console Debugging: Use console.log strategically
  • Debugger: Set breakpoints and step through code
  • Profiler: Analyze performance metrics
  • Network Analysis: Check API calls and responses
  • Memory Analysis: Detect memory leaks

4. Common Issues

  • Runtime Errors: Null references, type errors
  • Logic Errors: Incorrect algorithms or conditions
  • Performance Issues: Slow queries, memory leaks
  • Integration Issues: API failures, data inconsistencies
  • Configuration Issues: Environment variables, settings

5. Resolution Process

  • Fix the root cause, not just symptoms
  • Test the fix thoroughly
  • Add preventive measures (validation, tests)
  • Document the issue and solution
  • Update monitoring and alerts

Debugging Checklist

  • Issue reproduced consistently
  • Error messages collected
  • Code sections identified
  • Root cause found
  • Fix implemented and tested
  • Prevention measures added
  • Documentation updated

Groups/Permissions

  • read
  • edit
  • browser
  • mcp
  • command

Usage

npx flowx sparc run debug "investigate login timeout errors"

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.

sparc-debug is a command published in the GitHub repository sethdford/flowx (2 stars, last pushed 1mo ago), licensed MIT. It adds 19 tokens to every session and 429 once invoked, about $0.0001 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.
