Antigravity Compatibility

Antigravity is a first-class Meta Harness target. The shared Agent Skills tree is canonical; native profiles are optional and remain runtime-specific.

Paths

• Portable project skill: .agents/skills/harness/
• Portable user skill: ~/.agents/skills/harness/
• Native profiles: Antigravity’s configured custom-agent location (generated, not assumed by the portable contract)
• Durable portable artifacts: docs/harness/ and _workspace/

Keep native profile files out of the portable skill. If your Antigravity setup uses a different discovery location, configure that location in the runtime rather than forking .agents/skills/harness/.

Capability profile

Antigravity can consume skills and may provide custom agents, subagents, background execution, tool restrictions, model selection, and workspace isolation. Exact availability depends on the installed Antigravity surface and project policy. Confirm a capability before making it a correctness requirement; supported recursion is not a reason to build deep hierarchies.

Degradation

Map portable roles to the strongest verified capabilities. When isolation or exclusive ownership is unavailable, assign explicit non-overlapping paths or serialize mutable work. When parent/peer messaging or retained context is unavailable, use parent summaries and _workspace/ handoffs. Report the lowered capability rather than silently weakening the workflow.

Rippability

Delete Antigravity-native profiles or configuration without deleting the canonical skills, team contracts, or durable handoffs. See the portable contract, runtime capabilities, and compatibility matrix.
