SkillMaxx #1: we installed 902 things so you don't have to

803 worked. The other 99 have stories. Test data from Oct 25, 2026.

Since this issue: MCP servers are now tested in all 5 agents (Codex, Grok Build and Pi too, not only Claude Code and Cursor), and "broken" now means failed two nights running. The newest numbers are always on last night's report. Deep dives: MCP servers in Claude Code vs Cursor and 809 of 900 installs.

ok so here's the deal 👋

We take every agent skill, plugin and MCP server we can find, install it in a fresh sandbox in Claude Code, Codex, Grok Build, Cursor and Pi, and write down what happened. No vibes. Just logs.

This is issue #1. Here's the scoreboard.

The scoreboard (tested Oct 25)

Agent	Passed	Rate
Codex	65 / 65	100% 🏆
Grok Build	314 / 331	95%
Claude Code	338 / 367	92%
Pi	57 / 87	66%
Cursor (MCP servers)	29 / 52	56%
All	803 / 902	89%

The directory now tracks 424 skills, plugins and MCP servers.

Codex: flawless. Didn't even break a sweat. Cursor: 29 of 52 MCP servers connected in our keyless sandbox. Most of the misses want an API key or an account, so don't panic, just bring your own keys. Full list: https://skillmaxx.gilventures.ai/guides/best-mcp-servers-cursor/

Plot twist: "which auth0 did you mean?"

Four plugins that installed fine on Oct 16 now fail in Grok Build: auth0, grafana-mcp, postman, pr-review-toolkit. The plugins didn't break. The same names now live in more than one marketplace, so Grok politely refuses and asks you to pin one, like auth0@<marketplace>.

Fix: add the @qualifier. What does install in Grok Build: https://skillmaxx.gilventures.ai/guides/what-installs-in-grok-build/

New kid: videogen

videogen (Grok Build) does text → video, image → video, script → MP4. Passed its install test on the first try. Not saying it's showing off. It's showing off.

Crowd favorites (GitHub stars)

superpowers: about 305k ★
mattpocock-skills: about 303k ★
The official MCP reference servers (fetch, filesystem, git, memory, sequential-thinking, time): about 92k ★ each, and still the backbone of half the setups out there

Things that ghosted us

cyanheads PubMed MCP and gdharness stopped connecting in Claude Code (both passed Oct 16). gdharness also wants a Godot editor running. Fair, it's a Godot harness.
One Claude Code test (postiz) timed out talking to GitHub. Flaky network, not the plugin. Retesting.

How we test (20 seconds)

Fresh sandbox, no API keys, real agent CLI. Pass means the agent itself lists it as installed or enabled (for MCP, connected). Every result links to its log: https://skillmaxx.gilventures.ai/how-it-works/
