OpenCode + GNO

OpenCode with retrieval that does not bloat the prompt

Install the GNO skill for OpenCode and the agent gains a retrieval command it can call when it needs context, instead of carrying a knowledge base in every request. MCP is available too when you want Capsules, Knowledge Delta, and verified Ask exposed as structured tools.

Install

Connect OpenCode in one command.

gno skill install --target opencode
gno mcp install --target opencode
gno skill install --target all

What it unlocks

  • On-demand retrieval with no persistent prompt cost
  • Bundled recipes for lookup, capture, and citation
  • The same local index as your CLI and web UI

Prove it actually works

A written config file is not a working integration. GNO distinguishes the two, and so should you.

  • Run gno skill paths to see exactly where the skill was written.
  • Ask the agent to search your notes for a phrase only your corpus contains.
  • GNO cannot prove a client loaded an installed skill, so the retrieval answer is the proof. The install step reports what it wrote, not what the client did with it.
