tooluniverse-antigravity-plugin

Install, set up, verify, update, pin, uninstall, or troubleshoot the ToolUniverse plugin on Google Antigravity (AGY / Antigravity IDE / Antigravity 2.0). ALWAYS consult this skill for any of those — don't answer from memory, because the exact CLI name (agy), the "agy plugin install <path>" flow, the uvx tooluniverse MCP server, and the API-key env vars are easy to get wrong. Use it whenever someone wants to get ToolUniverse (or "the 1000+ scientific tools" / "the harvard tools") working on Antigravity, says the Antigravity plugin or its tools/skills won't load, hits a uvx or MCP-server startup error, asks how Antigravity updates it, wants to pin or remove it, or finds it running an old tool version. Not for the Codex plugin (use tooluniverse-codex-plugin) or Claude Code plugin (use tooluniverse-claude-code-plugin), for running research with the tools, or for authoring new tools or skills.

Content

100%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A concise, highly actionable install/setup guide with concrete commands, an explicit verification checkpoint, and a recovery table, all appropriately contained in one well-structured file.

Dimension	Reasoning	Score
Conciseness	The body is lean and task-oriented — sections like "Prerequisites (check once)", "Install", "Verify it worked", and "Troubleshooting" are command/table-dense with no concept-explanation fluff, assuming Claude's competence.	3 / 3
Actionability	It gives fully executable, copy-paste-ready commands such as "agy plugin install /path/to/ToolUniverse/plugin", "agy plugin list", "uv cache clean tooluniverse", and "uv python install 3.12", with expected output shown for verification.	3 / 3
Workflow Clarity	A clear sequence (prereqs → install → "Restart Antigravity" → verify) is paired with an explicit validation checkpoint ("agy plugin list" with expected JSON) and a troubleshooting table providing error-recovery feedback.	3 / 3
Progressive Disclosure	It is a well-organized, self-contained single-file guide with clear sections and a single appropriate external pointer ("Still stuck: https://github.com/mims-harvard/ToolUniverse/issues"), with no nested or multi-level references.	3 / 3
	Total	12 / 12 Passed

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

An exemplary description that states concrete lifecycle actions, supplies rich natural trigger terms, answers both what and when explicitly, and sharply disambiguates from sibling plugins.

Dimension	Reasoning	Score
Specificity	It lists multiple specific concrete actions — "Install, set up, verify, update, pin, uninstall, or troubleshoot the ToolUniverse plugin" — covering the full plugin lifecycle rather than a vague single verb.	3 / 3
Completeness	It clearly answers both what (the install/verify/update/uninstall lifecycle) and when, with an explicit trigger clause: "Use it whenever someone wants to get ToolUniverse… working on Antigravity, says the Antigravity plugin or its tools/skills won't load, hits a uvx or MCP-server startup error…".	3 / 3
Trigger Term Quality	It covers natural terms users would say, including "ToolUniverse plugin on Google Antigravity (AGY / Antigravity IDE / Antigravity 2.0)", "the 1000+ scientific tools" / "the harvard tools", "uvx or MCP-server startup error", and "pin or remove it".	3 / 3
Distinctiveness Conflict Risk	It carves a clear Antigravity-specific niche and explicitly redirects overlapping cases — "Not for the Codex plugin (use tooluniverse-codex-plugin) or Claude Code plugin (use tooluniverse-claude-code-plugin)" — making wrong-skill triggering unlikely.	3 / 3
	Total	12 / 12 Passed
