Create architecture, UI design, system tests, and detail design for a feature. Self-sufficient — if research/requirements missing, does them first. Does not depend on any other LLM.

Skill Claude CodeCodex
Implement a feature end-to-end. Self-sufficient — if research, requirements, or design are missing, creates them first. Covers implementation, testing, duplication check, refactoring, and verification.
Skill Claude CodeCodex
Collaborate through canonical LLM Caret rooms, task routing, context bundles, profiles, receipts, and artifacts.
Skill Claude CodeCodex
Plan, implement, or verify Simple parallel code involving tasks, actors, threads, processes, GPU/device work, transfer, memory layout, task arenas, mailbox bounds, or deterministic parent-authoritative commit. Use when mutable state crosses execution domains or when AoS/SoA/AoSoA policy affects concurrency safety or…
Skill Claude CodeCodex
Lazy senior developer mode: YAGNI -> Simple stdlib -> native/platform -> installed dependency -> one line -> minimum code. Levels lite/full/ultra, persisted in .simple/ponytail.level. Use on ponytail, be lazy, simplest solution, yagni, do less, over-engineering complaints.
Skill Claude CodeCodex
Version bump and release. Accepts version argument (major/first, minor/second, patch/third, or exact X.Y.Z). Defaults to patch. Updates all version locations, CHANGELOG, commits, tags, asks before push.
Skill Claude CodeCodex
Run local + domain research for a feature. Search src/ and doc/ for related code, web search for external knowledge, generate requirement options, ask user to select. Self-sufficient — does not depend on any prior step.
Skill Claude CodeCodex
Select and implement Simple FFI boundaries while preferring in-tree pure-Simple counterparts, especially PureDatabase over C SQLite wrappers.
Skill Claude CodeCodex
General protected software-release rules for stable and prerelease channels, maintenance backports, immutable candidates, and promote-without-rebuild publication.
Skill Claude CodeCodex
Production readiness verification. Checks SPipe tests for stubs/dummies, implementation completeness, requirement coverage, NFR targets, and architecture/design doc freshness. Self-sufficient — any LLM can run independently.
