code-repair-generation-combo

code-repair-generation-combo is a skill for Claude Code, Codex from ArabelaTso/Skills-4-SE. It costs 119 tokens per session (1,169 once invoked), scanned A, original, Apache-2.0.

A coding workflow for diagnosing and repairing logic or runtime bugs in Python, Java, and C++ programs, then creating tests for the corrected behavior. It can use descriptions, failing tests, examples, error messages, and stack traces as the specification.

In plain words
What is it for?
Use it to inspect buggy code, find root causes such as incorrect conditions or crashes, repair the code, and generate tests for individual functions, modules, or cross-module behavior.
Why use it?
It connects the bug diagnosis with tests that check the fix and help prevent the same problem from returning. It also helps trace whether the issue is limited to one function or spreads across modules.

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

code-repair-generation-combo 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 10d 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.

Code Repair + Generation Combo

Automatically diagnose and repair buggy code while generating comprehensive tests to verify correctness and prevent regressions.

Workflow

Follow this systematic approach for bug fixing and test generation:

1. Understand the Bug

Read the buggy code - Use Read tool to examine the problematic code thoroughly.

Analyze the specification - Understand expected behavior from:

  • Natural language description from user
  • Existing failing test cases
  • Input/output examples provided
  • Error messages or stack traces

Identify the scope - Determine if the bug affects:

  • A single function
  • Multiple related functions
  • An entire module
  • Cross-module interactions

2. Diagnose the Root Cause

Trace the logic - Walk through the code execution mentally or with examples.

Identify the bug type:

  • Logic error: Code runs but produces wrong results (off-by-one, wrong operator, incorrect condition)
  • Runtime error: Code crashes or throws exceptions (null pointer, array out of bounds, type mismatch)

Pinpoint the exact location - Identify the specific lines causing the issue.

Understand side effects - Check if the bug affects other parts of the codebase.

3. Fix the Code

Apply minimal changes - Fix only what's broken, preserve existing functionality.

Use Edit tool - Make precise changes to the buggy code.

Verify the fix logic - Ensure the fix addresses the root cause, not just symptoms.

Preserve code style - Match existing formatting, naming conventions, and patterns.

4. Generate Comprehensive Tests

Load testing patterns - Read the appropriate reference file:

  • Python: references/python-testing.md
  • Java: references/java-testing.md
  • C++: references/cpp-testing.md

Create test cases covering:

  • Normal cases: Typical valid inputs
  • Edge cases: Boundary values, empty inputs, single elements
  • Error cases: Invalid inputs, null values, exceptions
  • Regression cases: Specific inputs that triggered the original bug

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.
