The single entry point for ALL design and specification work. Use when designing, specifying, architecting, writing a spec, writing an RFC, writing a design doc, or drafting a design for any system, feature, product, protocol, game, or workflow. Trigger phrases include "design this", "design the system", "architect this", "draft a design", "design a feature", "design spec", "stress-test the design", "battle-test the design", "find flaws in this design", "design review", "harden the design", "pressure-test the design", "think through the design", "write a spec", "technical spec", "spec this out", "turn this into a spec", "write up the design", "RFC", "API design", "data model", "implementation spec". Default mode: adversarial stress-testing with parallel critics. Use --spec for lightweight single-session spec document generation (no critics).
EnglishRun harness gate checks at every development transition point. Enforces that all gates pass before the agent proceeds to the next phase.
EnglishBootstrap a Sisyphus-compatible engineering harness in any project. Generates HARNESS.md, FEATUREINTAKE.md, story template, HARNESSBACKLOG.md, optional OpenSpec config, GitHub issue tracking labels, and validation ladder customized to the project's stack via guided Q&A.
EnglishPersistent memory + code intelligence for AI coding agents. Hybrid search (BM25 + vector + RRF), cross-session recall, symbol graph analysis, impact checks, OpenCode/Claude Code session harvesting. Use when you need to recall prior decisions, search across sessions/codebase, trace symbol callers/callees, or persist long-term context.

Quick start
- Choose your skills. Select individual skills above, or choose the entire pack.
- Copy the install prompt. Use Copy install prompt above the list.
- Send it to your agent. Paste into your coding agent’s chat. Your agent reviews the source and guides the setup.
Try it with your agent
After installation, start with a request like:
Use the Deep Design skill to help with my task.
Ask me for the context you need before getting started.Requirements & license
- A coding agent that can access your project files and install skills.
- Your agent checks each skill’s instructions, dependencies, and permissions during setup.
- License details are not provided in these listings. Check the author’s terms before using the skills.
