+
+### OpenCode Bridge: Full Lifecycle Integration
+
+Complete bridge adapter for [OpenCode](https://opencode.ai) with first-run onboarding, session capture, and note validation.
+
+- **First-run onboarding** — plugin detects blank `identity.md` and injects onboarding prompt via `client.session.prompt()`
+- **Session capture** — `session.idle` hook fetches conversation messages via SDK `client.session.messages()` and saves via `ori add --content`
+- **Note validation** — `ori validate` runs silently when writing to vault notes
+- **Multi-vault support** — resolves vault path from `opencode.json` MCP config, works with any named MCP entry
+- **One-command install** — `ori bridge opencode --scope project --activation auto --vault /path/to/vault`
+- **Added `--content` flag to `ori add`** — allows programmatic note creation with real content (replaces template placeholder)
+
+The OpenCode plugin uses `spawnSync` for silent command execution (matching Claude Code's hook behavior) and `client.session.prompt()` for reliable onboarding injection.

-Claude Code and Hermes Agent are fully automated adapters with lifecycle hooks. Claude Code uses hook scripts; Hermes uses a native Python plugin installed at `~/.hermes/plugins/ori/`. Both auto-orient at session start and capture insights at session end. Cursor and Codex have native MCP config install support. Codex writes to `~/.codex/config.toml` and uses a single global config surface; "project" scope there means project-like runtime vault discovery, not a separate project config file. Other MCP-capable clients can use `ori bridge generic` now and wire the emitted config into their own client surface.
