ACP Migration Research

This folder captures the v2 migration plan from the current in-house protocol to ACP-first architecture.

Files

  • research/acp/00-delete-first.md: delete/comment-out-first inventory for the rewrite kickoff.
  • research/acp/acp-notes.md: ACP protocol notes extracted from ~/misc/acp-docs.
  • research/acp/acp-over-http-findings.md: field research from ACP Zulip thread on real ACP-over-HTTP transport patterns and recommendations.
  • research/acp/spec.md: proposed v2 protocol/transport spec (ACP over HTTP).
  • research/acp/v1-schema-to-acp-mapping.md: exhaustive 1:1 mapping of all current v1 endpoints/events into ACP methods, notifications, responses, and _meta extensions.
  • research/acp/rfds-vs-extensions.md: simple list of which gaps should be raised as ACP RFDs vs remain product-specific extensions.
  • research/acp/migration-steps.md: concrete implementation phases and execution checklist.
  • research/acp/friction.md: ongoing friction/issues log for ACP migration decisions and blockers.

Important context

  • ACP stable transport is stdio; streamable HTTP is still draft in ACP docs.
  • v2 in this repo is intentionally breaking and ACP-native.
  • v1 is removed in v2 and returns HTTP 410 on /v1/*.
  • /opencode/* is disabled during ACP core phases and re-enabled in the dedicated bridge phase.
  • Keep research/acp/friction.md current as issues/ambiguities are discovered.
