Q: How do I install code-debugging?

Run npx skills add https://github.com/lingzhi227/agent-research-skills --skill code-debugging in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/code-debugging/ (personal) or .claude/skills/code-debugging/ (project).

by lingzhi227Code Quality & Workflow

Debug experiment code with structured error analysis. Categorize errors, apply targeted fixes with retry logic, and use reflection to prevent recurring issues. Use when experiment code fails or produces incorrect results.

Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/lingzhi227/agent-research-skills --skill code-debugging

01
Install
Run the command in your project. The CLI asks which agents to install for.
02
Describe the task
Ask your agent for something this skill covers. It loads code-debugging automatically when relevant.
03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

Code Debugging

Systematically debug experiment code with structured error categorization and fix strategies.

Input

$0 — Error message, stderr output, or code file with issues
$1 — Optional: the code that produced the error

References

Workflow

Step 1: Categorize the Error

Category	Examples	Severity
SyntaxError	Invalid syntax, indentation	Low
ImportError	Missing module, wrong name	Low
RuntimeError	Division by zero, shape mismatch	Medium
TimeoutError	Infinite loop, too slow	Medium
OutputError	Missing files, wrong format	Medium
LogicError	Wrong results, 0% accuracy	High

Step 2: Analyze Root Cause

Read the error traceback (last 1500 chars if truncated)
Identify the exact line and variable causing the error
Check for common patterns:
- Device mismatch (CPU vs GPU tensors)
- Shape mismatch in matrix operations
- Missing data normalization
- Off-by-one errors in indexing
- Incorrect loss function for task type

Step 3: Apply Fix Strategy

For syntax/import errors: Direct fix, single attempt For runtime errors: Fix and rerun, up to 4 retries For logic errors: Reflect on approach, consider alternative methods For timeout: Reduce dataset size, optimize bottleneck, add early stopping

Step 4: Reflect and Prevent

After fixing:

Explain why the error occurred
Identify which lines caused it
Describe the fix line-by-line
Note patterns to avoid in future code

Fix Strategy State Machine

Stage 0 (first attempt) → repost code as fresh
Stage 1 (second attempt) → repost or leave depending on severity
Stage 2 (third attempt) → regenerate from scratch if still failing

Rules

Prefer minimal targeted edits over full rewrites
Maximum 4-5 fix attempts before changing approach
Always truncate long error outputs to last 1500 characters
After fixing, verify the fix doesn't introduce new errors
Keep error history to avoid repeating the same mistakes
If 0% accuracy: check accuracy calculation first, then check data pipeline
