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.

Quality

Content

82%Weight 40%Scale 1-5

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

The body is actionable and well-structured with concrete commands and a verification step, leaning efficient though slightly padded in the intro. The main gap is that the verify step is not explicitly linked to the troubleshooting recovery path.

Suggestions

Trim the promotional intro line and the "just ask naturally" example questions to tighten token usage.

Add an inline link from the Verify section to Troubleshooting (e.g., "If tooluniverse is missing, see Troubleshooting") to close the validation feedback loop.

Make the install sequence an explicit numbered checklist so the prerequisites → install → restart → verify order is unambiguous.

DimensionReasoningScore

Conciseness

Mostly lean with executable commands and tables, but the promotional intro ("an MCP server exposing 1000+ scientific tools plus 120+ research skills — all auto-configured") and the illustrative "just ask naturally" example questions are minor padding that could be trimmed.

4 / 5

Actionability

Fully executable, copy-paste-ready commands cover the common cases (uv/agy version checks, agy plugin install, agy plugin list, export of API keys, uv cache clean, uv python install), matching the top anchor.

5 / 5

Workflow Clarity

Clear sequence (Prerequisites → Install → Restart → Verify) with an explicit validation section showing expected output, but the verify-to-troubleshooting feedback loop is not wired inline, leaving a minor validation gap.

4 / 5

Progressive Disclosure

Well-organized into clear sections (Prerequisites, Install, Verify, What you get, API keys, Update, Troubleshooting) with content appropriately placed inline; no external references are needed, though the file exceeds the 50-line simple-skill threshold so the structure exception does not fully apply.

Description

100%Weight 40%Scale 1-5

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

The description is highly specific, complete, and distinctive, with concrete trigger phrases and explicit disambiguation from sibling skills. It is somewhat verbose with meta-commentary ("don't answer from memory..."), but this does not erode the measured dimensions.

DimensionReasoningScore

Specificity

Lists seven concrete actions — "Install, set up, verify, update, pin, uninstall, or troubleshoot" — giving comprehensive coverage of the plugin lifecycle, matching the anchor for multiple specific concrete actions.

5 / 5

Completeness

Explicitly states what (install/set up/verify/update/pin/uninstall/troubleshoot the ToolUniverse plugin on Antigravity) and when ("Use it whenever someone wants to get ToolUniverse... working on Antigravity") with concrete trigger phrases, satisfying the top anchor.

5 / 5

Trigger Term Quality

Covers natural phrasings users would say ("get ToolUniverse working on Antigravity", "won't load", "uvx or MCP-server startup error", "running an old tool version") plus synonyms ("the 1000+ scientific tools" / "the harvard tools"), matching comprehensive coverage with synonyms.

5 / 5

Distinctiveness Conflict Risk

Narrow niche (ToolUniverse plugin on Antigravity specifically) with explicit boundary guidance ("Not for the Codex plugin... or Claude Code plugin"), yielding minimal conflict risk.
