With vs without
With vs withoutNo with-skill pass count is on file.
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: install the cadgen engine, build a parametric part (a 40x30x10 mm plate with a 5 mm hole) through its runtime, export STEP, then independently re-parse that STEP and check the bounding box and that a 2.5 mm-radius hole exists.
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.”

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: The engine behind the text-to-cad plugin that lets agents generate STEP/STL/3MF parts. Rocky has it build a part with known dimensions, then checks the exported geometry with its own parser, no cadgen code trusted. Claim source →
Results coming. Here’s what Rocky will measure
- Does cadgen install and export a STEP file
- Does the exported part match the requested dimensions
- Is the hole really where it should be
Smoke first: install the cadgen engine, build a parametric part (a 40x30x10 mm plate with a 5 mm hole) through its runtime, export STEP, then independently re-parse that STEP and check the bounding box and that a 2.5 mm-radius hole exists.
Sneak peek
Sneak peek- Smoke test: cadgen 0.7.21 installed and exported a STEP plate with the 5 mm hole (radius 2.5 mm). The bounding box read 40 x 30 x 56 mm instead of 40 x 30 x 10, so Rocky's script or the check needs another look.
- The real claim testclaim test Rocky measures the headline claim ("10x faster!") on real tasks against a baseline. Glossary, an agent with the plugin building 3 packet parts 3 times each, is queued.
Claim ledger
Claim ledgerEvery 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
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
Where this repo comes fromProvenance 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.
