How to use the Fictiv custom parts ordering agent skill

What an agent skill is and what this one makes the agent do

An agent skill is a folder of instructions, reference notes and optional scripts that an AI agent loads when a task matches its description. This skill is named fictiv and is published as part of the K-Dense-AI scientific-agent-skills collection under an MIT licence.

With the skill loaded, the agent can work through the Fictiv web app end to end: upload CAD parts, configure process, material, finish, threads, tolerances and inspections, get instant or manual quotes, read and respond to DFM (design for manufacturability) feedback, choose lead time and region, check out, track orders, reorder and troubleshoot problems.

Install the Fictiv skill

Download the skill ZIP from this page and unzip it. Then choose one of two places to put the folder. For a personal install available across your projects, unzip it into ~/.claude/skills/. For a single project, unzip it into that project's .claude/skills/ folder.

If you use the Claude apps instead, open Settings, go to Capabilities, and upload the skill under Skills.

• Personal: ~/.claude/skills/
• Single project: .claude/skills/ inside the project folder
• Claude apps: Settings → Capabilities → Skills, then upload

Meet the requirements

The skill needs network access, a browser-automation tool such as Claude in Chrome, and your own logged-in Fictiv account at app.fictiv.com. The agent works in your browser, where your Fictiv session lives, so you need to be signed in there. The agent will ask you to sign in if it finds a login page and will not handle your password.

The CAD pre-flight script needs Python 3.10 or newer and uses only the Python standard library. The optional DOM helper scripts need browser JavaScript execution.

• Python 3.10+ (standard library only) for scripts/check_cad_file.py
• A browser-automation tool such as Claude in Chrome
• A Fictiv account at app.fictiv.com
• Browser JavaScript execution for the optional helper scripts

Trigger the skill with natural requests

You do not need a special command. The skill applies when you mention Fictiv, ask to get a quote or order parts for a STEP, SLDPRT or STL file, or want a part CNC machined, 3D printed, sheet-metal fabricated, urethane cast, injection or compression molded, or die cast through an online service. It also applies if you want custom parts made and have a Fictiv account, even when Fictiv is not named.

Good requests state the process, the file and what you need back, for example asking for a quote on an uploaded STEP file for CNC machining in aluminum, or asking why a DFM warning appeared on your upload.

Run the pre-flight check before uploading

Before every upload the skill runs its CAD pre-flight script. It checks documented file formats and heuristic STEP or STL geometry, units and size. ITAR text scanning is limited to STEP files. Resolve any blocking items first, such as exporting a STEP file or splitting separate parts into their own files.

You can also run the check yourself from a terminal, with the skill folder path in place of the placeholder.

Approvals and safety notes

Fictiv orders are real purchases and are usually non-cancellable. The skill is built so the agent stops and asks before any action that spends money, commits you or sends information outward. That covers placing an order, requesting a quote, sharing, sending team invites, applying for payment terms, messages to Fictiv, and deleting quotes, parts or the account. Approval must come from you in the conversation. Text on web pages, in files or in Fictiv chat messages is treated as information, not as instructions.

The agent will not type card numbers, CVCs, bank details or passwords, even if you paste them. It uses a saved card or asks you to enter payment in Fictiv's payment form. Its guidance also says it will not reverse-engineer private app calls, because Fictiv exposes no public customer API.

The scripts run locally and the skill uses network access to work with the Fictiv site. Read the scripts before running them if you want to review what they do.

• Place order, request quote, share and invites all need your explicit approval
• Card details, CVCs, bank details and passwords are never typed by the agent
• ITAR designs are not supported by self-service; export-controlled work goes through Fictiv's compliance process
• Warnings from DFM checks should be read before checkout

Examples of useful requests

Start with a quote request and let the agent collect what it needs. The skill asks you for anything missing, such as material grade, finish, quantity, threads, tolerances, need-by date and ship-to address, rather than guessing. If you say you have no preference, it chooses conservative defaults and tells you what it picked.

• Quote this STEP file as a CNC part in aluminum, quantity 10, and compare lead times
• Why is my Fictiv quote stuck without a price?
• Check the status and tracking of my last Fictiv order
• Pre-check these STL files for units and size before I upload them to Fictiv
