📄 Description

Summary

The agent markdown config files now support:

  • Instructions files
  • MCP servers
  • Resources (new feature, presenting a resource file as a tool for the LLM to call)
    image

Core Feature

  • Extended agent configuration to support mcp, instructions, and resources fields
  • Added Resource schema for specifying file resources with descriptions
  • Implemented dynamic resource tool creation from file paths
  • Added agent-specific MCP client management with AgentMCP module
  • Enhanced system prompt loading to include agent-level instruction files

Steps to test it:

  • Run npx openmodes install example at the root to install the agent file, its instructions and resources
  • Run opencode with bun dev
  • Press tab and select the "EXAMPLE" agent/mode
  • Ask: echo the verbatim list of tools you have access to, and give me the magic words

Success should show:

  • 3 repomix MCP tools out of 6 totals
  • 1 resource_the_other_magic_word tool according to our resource file name
  • Echo the first "magic word" supplied to the request through an instruction file
  • Get the resource with a tool call and echo the second "magic word"

Opening avenues

This ties in with the https://openmodes.dev project I've been working on lately (https://github.com/spoons-and-mirrors/openmodes.dev) and with the openmodes CLI tool, creating a simple way to discovering and using agents in OC.

Agents being integral to our agentic coding experience, I believe this PR allows for a better UX all around.
