Skill Codex
Diagnose reproducible failures and restore established behavior. Investigate missing facts; unresolved changes to user experience belong to product requirements.
Skill Codex
Turn visual goals, brand context and scenarios into a reasoned Design Brief. Use when visual or interaction rules change, not to restore established behavior.
Skill Codex
Create prototypes, wireframes and interaction states when a visual artifact will reduce uncertainty. Optional for new or changed designs; not required for routine maintenance.
Skill Codex
Implement a defined product or maintenance change, integrate results and verify relevant behavior. Use bug-fixer for unknown failure causes; independent review depends on concrete risk.
Skill Codex
Plan a clear outcome as a short task or dependent phases. Reuse active plans; use phases when requested or when deliverables need separate acceptance.
Skill Codex
Write a bounded, recoverable Goal with measurable acceptance only when the user explicitly requests a persistent or long-running goal. Never create unlimited retry loops.
Skill Codex
Turn an idea or product change into testable requirements. Use when intended user behavior or scope is unresolved; skip repeated interviews for already confirmed changes.
Skill Codex
Prepare builds, packages, smoke tests and release evidence for the actual project ecosystem. External publishing requires explicit authorization; a local build is not a release.
Skill Codex
Independently review R2 changes or an explicitly requested scope against effective contracts and behavior evidence. Do not revive retired obligations or repeat unchanged reviews.
Skill Codex
Merge demonstrated workflow failures and user corrections into evidence-backed rule improvements. Project preferences belong to project-knowledge, not global rule evolution.
Skill Codex
Create or refactor creator.skill capabilities when an existing skill cannot cover the required boundary. Maintain concise triggers, shared contracts and meaningful regression cases.
Skill Codex
A workflow initializer for creator.skill, a set of skills for gathering requirements, defining design rules, planning development, and building projects. It installs or upgrades the workflow in the current workspace from a release package or a local archive.
Skill Codex
Maintain current project knowledge, capture explicit design and release conventions during ordinary work, reconcile superseded decisions, and retire obsolete tasks without losing historical evidence. Use for scoped knowledge upkeep or authorized documentation cleanup, not for inventing product decisions or changing…
Skill Claude CodeCodex
A pragmatic working-rules skill for agents. It makes agents more direct, judgment-oriented, less repetitive, and more careful before executing complex tasks.
