A skill your agent uses when preparing a Formax code handoff: selecting files, generating repomix bundles, and writing a high-quality prompt for WebGPT or another coding agent with clear constraints…

yusifeng/formax

Set up, author, and navigate the dotagents standard — a slim AGENTS.md "router" at the repository root plus a hidden .agents/ directory (rules, context, memory, personas, skills, specs, logs, tasks)…

getknit/knit

Searches git repositories cloned locally under a sandbox folder to answer questions with cited links and complete code snippets.

Searches a codebase with hybrid semantic and lexical retrieval plus neural reranking through MCP tools, for finding implementations and grounded answers.

Fix drift in Home Assistant Homelab agent context (AGENTS.md, CLAUDE.md, .agents/context/, rules, skills, agents) against the repo.

Apocrathia/home-assistant-config

Chooses the right retrieval tool for code questions: compact context for unfamiliar repos, direct lookup for known symbols, call graphs for relationships and grep for exhaustive matches.

Verify which coding agent is running and that it loaded the shared Matterbridge instructions, rules and skills from AGENTS.md and .agents/.

Luligu/matterbridge

A skill your agent uses when a coding agent needs project knowledge from Terrain .terrain/ assets.
