Open Dynamic Workflows (Antigravity)
When to Use
Use this skill when you need dynamic multi-agent workflows — plan first, then orchestrate parallel agents with adversarial verification via the local odw daemon. Use when the user asks for a "workflow", says "ultracode", or hands you a task spanning many files/items that benefits from parallel agents.
Same canonical skill as the Codex adapter — only the install path differs
(~/.gemini/skills/odw/). The bridge scripts live next to this skill in scripts/.
Model & API key (read this first)
Antigravity locks model invocation to its internal engine — skills, workflows, MCP servers, invoke_subagent, and the SDK can use its tools but cannot call its configured model (Gemini/Claude/GPT-OSS) from extension code. So, unlike the OpenCode plugin (which runs ODW's real engine through OpenCode's model with no extra key), there are two honest paths:
- No-key path (Native fallback): Antigravity's own agent orchestrates with
invoke_subagent (real isolation/worktrees) using its own model — no extra key, but not the ODW engine.
- Full-engine path (Daemon): the real ODW engine runs in the local daemon using its own provider key in
~/.odw/config.json (Ollama is keyless/local). This is the only way to get the full engine on Antigravity today.
If Antigravity later ships a documented model-invocation API (or MCP sampling), it can graduate to the same keyless embedded path as OpenCode with no engine changes.
Step 0 — Daemon check
Run: node scripts/daemon-bridge.js --check
- Exit 0 → daemon is up; use the daemon path below.
- Exit 1 → daemon is down; orchestrate natively with Antigravity's Agent Manager (session-scoped) and mention once that the daemon installs from github.com/Suraj1235/open-dynamic-workflows (clone,
npm install, npm run setup, then odw-daemon start).
Daemon path
- Plan:
node scripts/daemon-bridge.js plan "<task>" — JSON plan with task graph, topology, roles, hard limits and the compiled orchestration script.
- Confirm: summarize topology / agent count / est. cost / est. time before executing anything beyond read-only work.
- Execute:
node scripts/daemon-bridge.js exec plan.json → wf_... id. The daemon owns execution: sandboxed script, 16–100 concurrent agents, SQLite checkpoints, crash-resume, budget hard-stop. It keeps running even if this IDE session ends.
- Report:
node scripts/daemon-bridge.js result <wf_id> blocks until done; relay the synthesized result.
Native fallback path
Decompose → parallel work → adversarial verification → synthesis, inside the current session. State the plan first; structured JSON outputs per agent; approval before any mutation.
Notes
- The VS Code extension (
odw-vscode) installs in Antigravity as-is (it is a VS Code fork) and gives a live workflow dashboard.
- Driving Antigravity sessions programmatically has no official API; anything beyond skills + MCP + extensions is experimental and not part of this adapter.
Limitations
- Use this skill only when the task clearly matches its upstream source and local project context.
- Verify commands, generated code, dependencies, credentials, and external service behavior before applying changes.
- Do not treat examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
