Included Skills4

agentic-sdlcskills/agentic-sdlc/SKILL.md

Use this skill when a user wants to run a contract-driven agentic SDLC in Codex or Claude Code, initialize or maintain a shared project knowledge base, create SDLC phase contracts, split work into story-scoped parallel tracks, validate gates, capture decisions/tests/traces, or use the Agentic SDLC plugin in a software project.

agentic-sdlc-assessmentskills/agentic-sdlc-assessment/SKILL.md

Contextualize an existing software project and deliver an initial technical, functional, architecture, or product assessment through a proposal-bound Agentic SDLC workflow. Use for natural requests in any language such as "contextualize this project", "contestualizza questo progetto e prepara un assessment", "assess the architecture and project health", or requests for a verified assessment artifact in Markdown, Word, Excel, PDF, PowerPoint, HTML, JSON, or CSV.

cavemanskills/caveman/SKILL.md

Ultra-compressed communication mode. Cuts output tokens 65% (measured) by speaking like caveman while keeping full technical accuracy. Supports intensity levels: lite, full (default), ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman. Also auto-triggers when token efficiency is requested.

change-observatoryskills/change-observatory/SKILL.md

Open the Change Observatory bundled with this Agentic SDLC plugin in Codex or Claude Code to inspect a project's recorded requests, decisions, contracts, changes, tests, gates, and lineage. Use when the user asks to open, launch, show, inspect, or explain the visual SDLC history or project change observatory.
