1. What OpenSpec Is OpenSpec is an open-source Spec-Driven Development framework maintained by Fission-AI. It does not try to teach AI new coding tricks. Instead it adds a lightweight “agreement layer” between you and the AI — before any code is written, both sides settle on what to do, in writing.

1. What Agent Skills Is Agent Skills is a production-grade engineering skill pack for AI coding assistants. It encodes the way senior engineers work — their working methods, quality gates, and best practices across the full Define → Plan → Build → Verify → Review → Ship lifecycle — into Markdown workflows (Skills) that an agent can execute.

1. What Headroom Is Headroom is a context compression layer for AI agents. Before the LLM receives a request, it performs content-aware compression on tool output, logs, RAG chunks, file contents, and conversation history, cutting token usage to 5%–40% of the original while keeping answer quality as unchanged as possible.

1. What CodeGraph Is CodeGraph is a local-first code intelligence tool. It parses a codebase with tree-sitter, stores symbols, relationships, and files in a local SQLite database, and exposes them as a queryable knowledge graph through MCP, a CLI, and a TypeScript API. Put simply, it turns “grep, glob, and Read all over the code” into an index built ahead of time, so an AI assistant can answer structural questions with just a few queries.

1. What Superpowers Is Superpowers is a plugin that bolts “engineering discipline” onto a coding agent, maintained by Prime Radiant. It is not a library of prompt templates but a complete software engineering methodology built on top of Skills — at session startup a bootstrap mechanism makes the AI automatically
