Commands and skills

In the BimSpeed AI chat box, type / to open a suggestion list of pane commands and skills. A skill is a ready-made workflow: the assistant follows it step by step, asks you for missing values and does not guess.

Feature in testing

BimSpeed AI is in testing. The list of commands and skills may change before the official release.

The suggestion list when you type /

The list is split into groups:

Group	Contains
Pane commands	Commands the BimSpeed AI pane handles itself (table below)
BimSpeed skills	Skills that ship with BimSpeed, with names starting bimspeed:
Your skills	Skills you wrote yourself in the second-brain folder

How to use it:

1. Type / and then a few letters to filter (for example /ki shows bimspeed:kiem-tra-model).
2. Use ↑ ↓ to move, Tab or Enter to choose, and Esc to close the list.
3. Add your request after the skill name if you like, for example /bimspeed:thep-dam beam 9129612.

Pane commands

Command	Description
/new	Start a new chat (reloads skills)
/resume	Reopen an earlier chat of this model
/model <name>	Change the AI model. With Antigravity it applies from your next message; with the other tools it applies to new chats (type /new). Type /model with no name to see the current model
/backend claude|codex|agy	Switch the AI tool for new chats. Type /new to start one now
/context	Attach the current selection and the active view from Revit. You can add a question after the command
/brain	Open the Brain folder. Change it: /brain set <path>; back to the default: /brain reset; open the settings: /brain config
/install [claude|codex|agy]	How to install and sign in to Claude Code, Codex and Antigravity
/help	Show the command list

Example: /backend agy then /new to use Antigravity for the new chat. You can also change it with the Tool box at the top of the pane.

BimSpeed skills

Four skills ship with BimSpeed. Their full names start with bimspeed:. All four read the project information and the values you agreed earlier from the second brain, and save new values when you confirm them.

/bimspeed:thep-dam: beam rebar

Place beam reinforcement with a safe workflow: filter beams, group them into runs, analyze spans, agree design values with you, preview, and only then create the rebar.

• Needs Edit model access for the create step. On Read only you can still preview.
• The assistant does not infer structural reinforcement: bar counts, diameters, stirrups, stirrup spacing and cover must come from you, the project's notes or a document in knowledge.
• The beams currently selected in Revit are used if you do not give IDs or a level.
• After creating, the assistant checks the result and reminds you to verify bar lengths, splice positions and anchorage.

Example: /bimspeed:thep-dam the selected beams

/bimspeed:ban-ve-dam: beam drawings

Create annotated beam drawings (elevation and sections) on a sheet, inspect the result visually and correct viewport placement.

• Needs Edit model access.
• The beams in the drawing must already have rebar. If not, the assistant suggests running /bimspeed:thep-dam first.
• The assistant asks for the sheet number and title block type if it does not have them.
• After creating, the assistant captures the sheet to review it and adjusts viewport positions if needed. Anything still wrong is reported so you can fix it by hand.

Example: /bimspeed:ban-ve-dam the selected beams, sheet A3

/bimspeed:kiem-tra-model: model overview check

Quick review of the open model: element counts by category and level, levels and grids, material quantities, anomalies.

• Read only, never changes the model.
• Writes a summary to the project's PROJECT.md (the Tổng quan section) and a longer report into the project's outputs folder.
• Only points out what the numbers it just read show; it does not draw conclusions about structural design.

Example: /bimspeed:kiem-tra-model

/bimspeed:thep-toan-model: bulk rebar

Place rebar in bulk for beams, columns or the whole model in the scope you pick: dry run, confirm the scope, run for real, then monitor progress.

• Needs Edit model access for the real run.
• You choose the element kind (beams, columns or both), the scope (whole project, active view or current selection) and the level.
• Each element is processed independently; rebar is not made continuous across several spans or levels. For continuous rebar along a beam run, use /bimspeed:thep-dam.
• Elements that already have rebar are skipped by default.
• "Created" only confirms that new rebar exists; it does not prove the layout is right. Check it in Revit, especially stepped beams and columns cut by slabs.

Example: /bimspeed:thep-toan-model beams on level 2

Your skills

You can write skills for your company's own workflows and call them with /<skill-name>. See Second brain: add your own skill.

An example, /vi-du, is provided in the Brain folder to show how one is written.

New skill not showing?

A new skill appears after you press New or type /new.
