Host: Codex CLI — This skill was designed for Claude Code and adapted for Codex. Cross-reference commands use installed skill names in Codex rather than /octo:* slash commands. Use the active Codex shell and subagent tools. Do not claim a provider, model, or host subagent is available until the current session exposes it. For host tool equivalents, see skills/blocks/codex-host-adapter.md.

Systematic Debugging

MANDATORY COMPLIANCE — DO NOT SKIP

When this skill is invoked, you MUST follow the 4-phase debugging process below. You are PROHIBITED from:

• Jumping straight to a fix without completing Phase 1 (Root Cause Investigation)
• Skipping the hypothesis step and guessing at solutions
• Deciding the bug is "obvious" and bypassing the systematic process
• Attempting more than 3 fixes without stopping to ask the user

Systematic debugging finds root causes in 15-30 minutes. Random fixes waste 2-3 hours. Follow the process.
