Agents Auto-Discover the MCP Tools

0.4.0

Installing the MCP server gave agents the tools, but not a reason to reach for them. Archcore now writes a short “use Archcore” hint into each detected agent’s instruction file, so agents discover and call the document tools instead of leaving them idle.

Improvements

  • New archcore instructions install — writes the “use Archcore” hint into detected agents’ instruction files (AGENTS.md, GEMINI.md, .claude/rules/) so agents actually call the MCP tools.
  • New archcore instructions remove — strips the hint, even after the project has been de-initialized.
  • archcore init now offers to add the hint after agent setup (opt-in, default yes); non-interactive runs skip it and point to archcore instructions install.
  • New --agent <id> flag on both subcommands targets a single host instead of all detected ones.
  • Shared files (AGENTS.md, GEMINI.md) are edited non-destructively inside a managed <!-- archcore:start --> marker block, so the hint can be updated or removed without touching your own content.
