fix(antigravity): correct base_dir + support .agents/ canonical paths#46
Merged
Conversation
Antigravity has two on-disk directories: ~/.antigravity/ (the VS Code-fork IDE shell, undocumented by Google) and ~/.gemini/antigravity/ (the AI agent runtime — every Antigravity-related path Google's docs and codelabs reference lives here). HK previously used the IDE shell as base_dir, which led to: - skill_dirs writing to ~/.antigravity/skills/ — a path Antigravity does not scan; installs landed in a directory the agent ignores - plugin_dirs scanning ~/.antigravity/plugins/ — fabricated; Antigravity has no file-based plugin system (its "plugin" surface is VS Code VSIX extensions in ~/.antigravity/extensions/, a different extension class) - hook_config_path pointing at ~/.antigravity/settings.json — a non-existent file (dead code since hook_format=None, but misleading) Switch base_dir to ~/.gemini/antigravity/ so skill_dirs/mcp_config_path/ global_settings_files all resolve to the documented agent paths via base_dir. Empty plugin_dirs (no plugin surface). Park hook_config_path on a clearly inert placeholder. Update the in-test setup path to match.

Antigravity 1.18.4+ migrated workspace config directories from `.agent/` (singular) to `.agents/` (plural). Per Google staff on the AI Developers Forum, `.agents/` is canonical going forward and `.agent/` is kept as backward-compat. The new "Getting Started with Google Antigravity" codelab uses `.agents/` throughout, while the older Skills codelab still references the singular form. - project_skill_dirs: list `.agents/skills` first so new installs land on the canonical path; keep `.agent/skills` as fallback for projects that haven't migrated. - project_markers: detect either form so HK recognizes both pre- and post-1.18.4 Antigravity projects. - project_rules_patterns: scan both; previous "backward compat" comment on the plural entry was inverted and is removed. - mod.rs upstream-conventions test: expected canonical workspace skill path updated to `.agents/skills`.

Summary
base_dircorrection: Antigravity has two on-disk directories —~/.antigravity/(VS Code-fork IDE shell, undocumented by Google) and~/.gemini/antigravity/(the AI agent runtime, where every Antigravity-related path Google's docs reference actually lives). HK previously used the IDE shell asbase_dir, causingskill_dirsto write to a directory Antigravity doesn't scan,plugin_dirsto point at a fabricated path, andhook_config_pathto point at a non-existent file. Switchbase_dirto~/.gemini/antigravity/; consolidate skill/MCP/settings paths viabase_dir().join(...). Emptyplugin_dirs(Antigravity has no file-based plugin system; its "plugin" surface is VS Code VSIX extensions). Parkhook_config_pathon an inert placeholder (dead code sincehook_format=None)..agents/canonical path support: Antigravity 1.18.4+ migrated workspace dirs from.agent/(singular) to.agents/(plural). Per Google staff on the AI Developers Forum, plural is canonical going forward; singular kept as backward-compat. Updateproject_skill_dirs,project_markers, andproject_rules_patternsto scan/install both forms, plural first.Why
Surfaced while triaging issue #22 item 5 (the user's question about whether HK differentiates Gemini CLI from Antigravity). Verification of the install pipeline against Antigravity's actual on-disk paths uncovered: (a)
~/.antigravity/skills/was never read by Antigravity (HK had been creating an empty orphan directory there during scans), and (b) HK still treated.agent/as the only canonical workspace path, missing the.agents/migration.Path facts cross-verified against:
Global rule: ~/.gemini/GEMINI.md,Workspace rules: your-workspace/.agents/rules/,Workspace workflows: your-workspace/.agents/workflows/,Global workflow: ~/.gemini/antigravity/global_workflows/~/.gemini/antigravity/skills/(global),.agent/skills/(workspace, older convention)antigravity.google/docs/mcp:~/.gemini/antigravity/mcp_config.json.agents/, but we do have backward support for.agentstill….agents(plural) should be used"product.json:dataFolderName: ".antigravity"(the IDE shell folder, never user-documented)What's NOT in this PR
