+## [Unreleased]
+
+### Added
+
+- **OpenCode Agent Adapter** - Added `OpenCodeAdapter` to `agent-manager` so `ai-devkit agent` commands can discover, inspect, and control running OpenCode sessions (#82).
+- **HTML Artifact in `document-code` Skill** - The `document-code` skill now offers an HTML artifact alongside its markdown output (ff9d3bb).
+
+### Fixed
+
+- **Claude Code PID-File Live Status** - `agent-manager` now prefers the PID-file live status when resolving Claude Code agent state, improving accuracy of `agent list` output (f4e189d).
+- **Claude Code Lossy Project Dir Encoding** - `agent-manager` now matches Claude Code's lossy project directory encoding when resolving session paths, fixing session discovery for paths that Claude Code re-encodes (a98e7ac).
