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.
