Chat & Build

Korras Agents uses one conversation model with two modes. Modes change what the session is allowed to do — they are not separate products.

Chat mode

Use Chat mode to:

Brainstorm workflows and agent designs
Ask questions with platform tools
Explore data and documents safely

Mention tools with @. Korras ships 12 platform tools, including:

@web_search — search the public web
@web_fetch / @page_scrape — pull readable page content
@pdf_extract — extract text from a PDF
@json_query / @csv_query — query structured data
@youtube_transcript — pull a video transcript
@docs_crawl, @arxiv_lookup, @calculate, @get_current_time, and more

See the full list in Tools & integrations.

If a request is outside what Chat mode can do, the platform records a clear capability boundary instead of inventing an action.

Build mode

Use Build mode to scaffold product artifacts:

Agents (mission, role, backstory)
Recipes and task packs
Tools and skills

Build mode is where the Agent Builder and Tool Builder pipelines run. Prefer Build when you want something created or changed in your workspace — not just discussed.

Switching modes

You can switch between Chat and Build on the same session. History stays with the session; only the capability policy changes.

Tips

Start in Chat to clarify the problem, then switch to Build to create the agent
Use @ tool mentions when you need grounded research
Keep secrets out of chat — credentials are collected through the platform registry when tools need them
