Ajay Krishnan 65ee701cae Add README + CHANGELOG for v0.0.1.alpha1
README (~140 LOC):
  - Why this gem exists (4 production needs opencode-ruby alone doesn't cover)
  - Install + quickstart (showing GenerateResponseJob wiring Session + Turn)
  - 12-constant API table with one-line role descriptions
  - Instrumentation + error-reporting adapter setup snippets
  - Position against opencode-ruby and Eric Guo's opencode_client

CHANGELOG documents what shipped, runtime deps, and known limitations
(apply_patch artifact drop, gem-side behavioral tests TBD, no Rails
generator yet). LICENSE was auto-generated by Gitea (MIT, 2026
ajaynomics) and is unchanged.

Changelog

0.0.1.alpha1 — 2026-05-20

Initial public alpha. Extracted from a production multi-product Rails app (ajent-rails) where these objects shipped under lib/opencode/rails/ before being carved out into a standalone gem.

Includes:

  • Opencode::Session — AR-coupled, row-level-locked session lifecycle (ensure!, recreate!, abort!)
  • Opencode::Turn — orchestrator covering send → stream → recover → finalize, with CAS-safe message terminal-state transitions
  • Opencode::Exchange — domain object over a turn's message array; emits opencode.apply_patch.artifacts_dropped when post-write file content is unavailable
  • Opencode::Artifact — value-object (filename + content + content_type + trust metadata), idempotent attach
  • Opencode::MessageArtifacts — ActiveStorage-aware artifact attachment pipeline with transform support
  • Opencode::Sandbox — disk-backed sandbox reader, returns Artifact list
  • Opencode::SandboxFile — single-file value object (pathname → bytes/content-type)
  • Opencode::Transform — base class for content-rewriting transforms
  • Opencode::Impostor — ActiveStorage download/upload round-trip helper
  • Opencode::UploadedFilesPrompt — user-prompt prefix builder listing uploaded files, sandbox-path inverted (injection-based, no Opencode::Permissions reference)
  • Opencode::ToolDisplay — view-model for tool-call hashes (Turbo Stream-friendly)
  • Opencode::ErrorReporter — pluggable adapter mirroring the Opencode::Instrumentation pattern

Runtime dependencies:

  • opencode-ruby ~> 0.0.1.alpha1 (wire client + Reply state machine)
  • activerecord >= 7.1, < 9.0
  • activestorage >= 7.1, < 9.0
  • activesupport >= 7.1, < 9.0

Known limitations (alpha):

  • Apply-patch tool's post-write file content is not extracted (wire-format limitation in OpenCode v1.15+); affected files surface via the opencode.apply_patch.artifacts_dropped instrumentation event. Future work: optional sandbox-read fallback path.
  • Smoke tests only inside the gem (14 tests). Behavioral coverage lives in the host app that originally produced this code (ajent-rails's test/lib/opencode/rails/). Standalone gem-side test suite using Combustion is open work.
  • No generator (rails g opencode:install) yet.
  • No Rails Engine integration — require "opencode-rails" is sufficient.
