argus

Guides the design and structuring of AI agent skills for the Argus repository with multi-step phases, progressive disclosure, and dual-platform compatibility (GitHub Copilot and Claude Code / OpenCode). Use when creating new skills, reviewing existing skills, restructuring AI guidance into modular skill directories, editing SKILL.md files, or improving agent instructions.

Use when asked to generate an implementation plan, draft a plan, save a plan, or design a feature rollout for the Argus repository. Supports two formats: full 7-section plans for multi-phase work (1K+ LOC, tracked in MASTER.md) and lightweight mini-plans for single-PR changes (under 1K LOC, stored in docs/plans/mini-plans/). Routes automatically based on PR plans label, user input, or task size estimate.
