SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? AI coding sessions often skip established workflows, jumping straight into ad-hoc answers or edits. This Skill establishes a mandatory discipline: check for and invoke relevant skills before any response, and delegate all implementation work to Codex GPT-5.6 models while Claude handles orchestration. ## Core Features & Use Cases - Skill-First Rule: Requires invoking any applicable skill before responding, asking clarifying questions, or exploring the codebase, with a red-flags table that counters common rationalizations for skipping skills. - Delegation-First Rule: Routes all implementation work (writing or changing product code) to Codex GPT-5.6 via the codex-delegation skill, while Claude retains brainstorming, planning, review, verification, and git operations. - Skill Priority Ordering: Defines precedence when multiple skills apply — process skills (brainstorming, systematic-debugging) run first, then implementation skills carry out the work. - Use Case: When a user says "fix this bug", the session invokes systematic-debugging before touching code, then delegates the resulting fix implementation to Codex and reviews the diff. ## Quick Start Start a new conversation and ask Claude to fix a bug or build a feature, and it will invoke the appropriate supercodex skill before responding.

Frequently Asked Questions about using-supercodex

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I make Claude Code always use skills before responding?▼

Install the supercodex plugin, whose using-supercodex skill mandates invoking any applicable skill before responses, clarifying questions, or codebase exploration. It includes a red-flags table that blocks common rationalizations for skipping skills.

How does Claude delegate implementation work to Codex?▼

The delegation-first rule routes all product code changes to Codex GPT-5.6 models via the codex-delegation skill. Claude keeps orchestration duties: brainstorming, planning, reviewing Codex diffs, verification, and git operations.

Which skill runs first when multiple skills apply?▼

Process skills run first because they set the approach, then implementation skills carry it out. For example, "fix this bug" triggers systematic-debugging before any domain-specific implementation skill.

Does this skill apply to subagents executing specific tasks?▼

No. The skill contains an explicit SUBAGENT-STOP directive: if the AI was dispatched as a subagent to execute a specific task, it must ignore this skill entirely and proceed with its assigned work.

Can user instructions override the skill-first rule?▼

Yes. User instructions from CLAUDE.md, AGENTS.md, or direct requests take precedence over skills, which in turn override default behavior. Skill workflows are only skipped when the user explicitly says so.
