The Shark Pattern — universal non-blocking execution for any AI coding agent. Spawn remoras for slow tools, keep the main agent swimming. Works with Claude Code, Codex, Gemini CLI, Cursor, Aider, OpenClaw.
Skill Claude CodeCodex
Use when: user wants to select architecture patterns, compile a spec, iterate on constraints/NFRs, audit why patterns were selected/rejected, or finalise an architecture for implementation. Not when: no repeatable decisions needed, or constraints/NFRs are not yet known (gather those first).

Use when creating or improving an agent Skill (writing or editing a SKILL.md) — selects and applies the skill-design patterns the skill's purpose calls for, so the author doesn't have to hand-pick them. Triggers on "create a skill", "write a SKILL.md", "improve this skill", "make a skill that…", "turn this into a…
