Platform skills vs your own skills

TrainAR delivers skills to the on-glasses AI through three tiers: system skills that are always present, platform skills that come from Marketplace bundles, and account skills that you build yourself.

System skills

System skills are built into every TrainAR session. They require no configuration, can't be removed, and every seat on every account has access to them.

Skill	What it does
search_knowledge	Semantic search across all knowledge documents your account has uploaded. The AI calls this when the engineer asks something whose answer is likely in your manuals or procedures.
capture_camera	Grabs a single frame from the engineer's POV. Used by other skills that need a visual reference.

System skills don't appear in the Skills tab — they're under the hood.

Platform skills

Platform skills are delivered via Marketplace bundles. Subscribe to a bundle and the bundle's skills become available to your seats automatically. They show in the Skills tab in a read-only section — you can see them, see what they do, but you can't edit their fields (the bundle owns them).

The clearest example today is the Parts & Spares bundle, which adds five Parts Arena skills:

Skill	What it does
pa_identify_model	Identify a boiler from its GC number, model name, or photo
pa_get_parts_list_for_model	List the parts catalogue for a specific appliance
pa_search_parts	Free-text search across the parts catalogue
pa_show_manual_page	Surface a relevant page from a manufacturer's installation/servicing manual to the AR display
pa_show_exploded_view	Surface an exploded diagram to the AR display

Cancelling the bundle removes the platform skills from the AI's available set on the next session.

Account skills

Account skills are skills you author for your own account. They sit at the top of the Skills tab, fully editable. Typical examples:

• Customer lookup — hits your CRM/FSM to fetch customer details by phone, email, or job ID
• Warranty status — hits your warranty system or manufacturer API
• Parts pricing — hits your supplier's pricing API
• Stock check — hits your van-stock system
• Job completion writeback — POSTs a completion event back to your job-management system

Account skills are scoped to your account only — they're never visible to anyone else.

Assignment scope — org vs seat

Whether platform or account, every skill has an assignment scope:

• org — every seat in your account gets this skill (default for account skills)
• seat — only the seats you explicitly assign get it

Use seat-scoped assignment when a skill is only relevant for a particular role (e.g. a stock-check skill that only applies to van engineers, not office admins recording desk-procedures).

Manage assignment from the skill row → Assigned roles field, or per-skill from Skills & Knowledge → Skills → row → Edit → Assignment scope.

How the AI chooses between skills

When the engineer says something, the AI scans all skills available to that seat (system + platform + account), matches against each skill's description, and picks the best fit. If the AI can't find a strong match it just answers conversationally without calling a tool.

The description IS the matching signal — see Creating a custom skill for how to write effective descriptions.

Content for your region

Some platform skills, knowledge and forms are specific to a country. The library only shows you the content that applies to where your account is based, so a UK account sees UK gas, electrical and oil paperwork while an account in another country sees the content relevant to it. You don't need to do anything — you simply see what's right for your region, and content that applies everywhere shows for all accounts.
