+**Installing GSD into Antigravity now writes the `permissions.allow` rules its CLI documents** — so GSD's own reads and hooks aren't stuck on interactive prompts — and registers GSD's companion MCP server via a standalone `mcp_config.json` (best-effort: Antigravity's raw config schema isn't published, so this uses the Gemini-CLI-successor format). Antigravity's install is now driven by its negotiated capability descriptor instead of hardcoded runtime special-cases. (#2096)

+**Augment Code now installs through its capability descriptor, with a native MCP companion** — installing GSD into Augment registers the GSD companion server in Augment's `settings.json` `mcpServers` and drives command/skill/agent conversion from Augment's negotiated descriptor instead of hardcoded runtime special-cases.

+**CodeBuddy now wires GSD's full extended lifecycle hook set and is driven by its capability descriptor** — installing GSD into CodeBuddy now registers `SubagentStart`, `SubagentStop`, `Stop`, and `PreCompact` hooks in its `settings.json` (it previously had none of these), matching the coverage Qwen/Kimi already ship, and CodeBuddy's install is fully descriptor-driven instead of via residual hardcoded runtime branches.
