   Documentation Devourer

Devour scrapes, indexes, and serves documentation from multiple sources
(GitHub repos, OpenAPI specs, web docs, local files) to feed structured
context to AI models for generating accurate, fully working code.

Runs in two modes:
  - Local mode: OpenCode skill running entirely on your machine
  - Remote mode: MCP server for multi-user/team access`,
