With vs without

With it loadedNot tested yet

No with-skill pass count is on file.

Without itNot tested yet

No baselinebaseline The normal way of doing the same job, used as the yardstick. Rocky compares every claim against a baseline on the same machine. Glossary pass count is on file.

Usefulness is a separate question from “does the repo exist.” It needs the same task run twice. Until that A/B is published, both cells stay blank.

What the test plan says

Smoke first: clone, install, import the server and count the MCP tools it registers (claims 101 tools, or a 21-tool core). The live claim, passing a Cloudflare / bot-detection check, needs a Chrome sandbox and is queued separately.

Four verdicts

One stamp is not the whole story. Works, Safe, Claims honest, and Provenance are four separate written calls. A missing call stays “not tested yet.”

WorksNOT TESTED YETDid it do the thing when Rocky ran it?

No written call is on file. This is not a pass.

SafeNOT TESTED YETSafe to install and run?

No written call is on file. This is not a pass.

Claims honestNOT TESTED YETDoes the pitch match what Rocky measured?

No written call is on file. This is not a pass.

ProvenanceNOT TESTED YETDoes the repo's history check out?

No written call is on file. This is not a pass.

Safety is a hard cap. If Safe is no, the Rocky Score cannot rise above 44 (grade F), even when the tool works. A blank Safe card means not tested yet, not safe. How the four verdicts roll up →

What it is: An MCP server that drives a real Chrome browser (via nodriver + CDP) to get past Cloudflare and bot checks, with a claimed 101 tools. Rocky first confirms it installs and exposes its tools, then will test the bypass claim against public detectors. Claim source →

Results coming. Here’s what Rocky will measure

  • Does it install and expose its MCP tools
  • How many tools are really there vs the claimed 101/21
  • Does it pass public bot-detection checks (claim run, queued)

Smoke first: clone, install, import the server and count the MCP tools it registers (claims 101 tools, or a 21-tool core). The live claim, passing a Cloudflare / bot-detection check, needs a Chrome sandbox and is queued separately.

Sneak peek

Claim ledger

Every distinct claim in the pitch gets a row: what was said, what the command said back. 1 claim on the ledger: 1 not measured. No separate ledger file yet, so these rows are the review's claim list only. “Not tested” means that claim has no measurement.

🔍 Coverage: Not stated yet. Rocky only lists the parts a run actually checked.

⚗️ Unproven usefulness. Counting and parsing can settle what the repo claims. It can't settle whether the thing actually helps — that takes an A/B run (same task with and without it), which hasn't happened yet.

Rocky's take

Not written yet.

Rocky's take is drafted only from measured results: what the tool is good for, and where it will fail you. Until those results exist, this stays blank. Nothing here is guessed.

Where this repo comes from

Not checked yet.

Provenance is age, authors, commitcommit One saved version of a repo's code. Rocky pins the exact commit so anyone can rerun the same code. Glossary · Learn more bursts, and where the README sends you. It is published only from commands Rocky ran. Nothing is guessed, so this section stays blank until that file exists.
