Curated by Skill Harbor — a part-discovery skill for CAD assemblies: search the hosted step.parts catalog (API-first, not scraping) for named off-the-shelf components — actuators, servos, motors, electronics boards, connectors, screws, bolts, nuts, washers, bearings, standoffs — resolve fuzzy model names and vendor aliases (e.g. STS3215/ST3215/Waveshare Feetech), pick the exact match, then download the canonical STEP file and verify its checksum via the bundled downloader script, falling back to a documented simplified envelope only when the API was reachable and returned no match. By @earthtojake, listed here with credit to its creator. Honest caveats: uses the external step.parts API (canonical origin api.step.parts) — no local catalog, so searches need network access; results are limited to what the catalog carries; the CAD viewer handoff at the end only works if the companion $cad-viewer skill is installed. Skill Harbor never reviews the code, review it yourself before use. Discovered via skills.sh.

Install
Prerequisites: Python 3 for the bundled downloader script, outbound network access to api.step.parts; the $cad-viewer skill if you want automatic handoff of downloaded STEP files Install "STEP Parts: purchasable CAD parts finder" for me. Give my agent the step-parts contract from earthtojake's text-to-cad repo: interpret a part request into search terms and facets, query the step.parts /v1/parts API (trying model aliases and vendor spellings before giving up), present the best matches with id, name, standard and key attributes, download the chosen record's canonical STEP file and verify its sha256 with the bundled scripts/download_step_part.py — and only use a documented simplified placeholder when the API was reachable and returned no relevant candidates Repository: https://github.com/earthtojake/text-to-cad/blob/main/skills/step-parts/SKILL.md 1. Fetch the SKILL.md file (and any helper files) from the repository path into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "earthtojake-text-to-cad-step-parts". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. confirm the api.step.parts origin is reachable from my sandbox and install the companion $cad-viewer skill for automatic handoff). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
