Official, Anthropic-managed directory of high quality Claude Code Plugins.
Runssource: GitHubPythonApache-2.0commit 58267944f921
Python, Apache-2.0 licensed. The project labels itself: claude code, mcp and skills.
claude-plugins-official runs. An Argusic agent installed it in 6 minutes and hit 3 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
Frontmatter validation passes on 102 files (0 errors), code-modernization plugin tests pass 143/143, fakechat MCP server answers HTTP 200 on port 8787, claude-code CLI 2.1.310 installed locally, 40/40 vendored plugins have valid Apache 2.0 LICENSE files, and marketplace.json lists 315 plugins (53 vendored, 262 external).
What the agent ended up with on a clean machine, in its own words. How this is measured
Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 60 of 100 (the mean of this project's run scores).

What was measured
From the run that decided this verdict. Every line is a recorded value, not an estimate.
What went wrong, in the agent's own words
The agent's own words, worst first, never rewritten into advice.
- 4 agent .md files had YAML frontmatter parse failures because validate-frontmatter.ts's quoteSpecialValues() treated `|` (a YAML block scalar indicator) as a special character needing quoting, producing invalid YAML3 minutes
- npm install -g failed with EACCES (no root permissions)1 minute
- bun not pre-installed in the container; required for MCP server TypeScript files1 minute
- Install time
- 6 minutes
- Cold machine to finish
- 6 minutes
- Errors hit and fixed
- 3 hit, 3 fixed with no human help
- How the result was proved
- npx bun .github/scripts/validate-frontmatter.ts exited 0 (102 files, 0 errors); npx claude plugin test in plugins/code-modernization gave 143 pass, 0 fail; curl localhost:8787 returned 200; /work/repo/node_modules/@anthropic-ai/claude-code/bin/claude.exe --version returned 2.1.310

What was not measured
The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.
- Peak GPU memory
- this ran on a CPU machine, so there was no GPU to sample
- Behaviour over a long run
- each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load
The end of the recording
The last lines of the terminal session that decided this verdict, exactly as they were recorded.

How it was tested
One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.
Strengths and limits
Measured facts, not opinions. How this is written.
What went well
- Reached a running state on a clean machine, with the session recorded.
- Recovered from all 3 errors without a human stepping in, which says the failures are documented well enough to solve.
- Ran without a GPU, so it does not need one to start.
- Licensed Apache-2.0, as reported by its host.
- Measured 2 times, so the result is not a one-off.
What did not, or is not known
- Took 6 minutes to install, slower than the median of the 13 comparable projects Argusic has measured.
Of the 14 claude-code projects Argusic has installed and timed, claude-plugins-official was the 8th fastest to reach a running state, and 13 of 14 reached one at all.
What it is a reasonable choice for
- Trying it on a laptop or a small server: it reached a running state without a GPU.
- A quick evaluation: it was running 6 minutes after the clone.
Also tested, in the same area
Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

- How did Argusic test claude-plugins-official?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 58267944f921. 2 attempts are recorded, and the full method is on the methodology page.
- What did it cost to test claude-plugins-official?
- The run that produced this verdict cost $0.06: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does claude-plugins-official take to install?
- 6 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
- Does claude-plugins-official need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing claude-plugins-official?
- 3 things broke in the recorded run, and 3 were fixed without human help. Each one, and the time it cost, is listed on this page.
- How does claude-plugins-official compare with the alternatives?
- Of the 14 claude-code projects Argusic has installed and timed, claude-plugins-official was the 8th fastest to reach a running state, and 13 of 14 reached one at all.
- Where is the evidence for claude-plugins-official?
- All 2 recorded runs are on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
