// AFK

Away From Keyboard building for owned projects with AI.

AFK (Away From Keyboard) is AlgoArena's early agentic builder lane. The demo should feel real enough to communicate the direction, while staying honest that the public surface is still being defined.

The near-term contract is ownership: real files, clear status, export paths, and eventually GitHub/deploy handoff.

AFK concept surface

Make the future product concrete without squeezing the interface.

The page should show one believable workspace, then explain the product contract around it: owned files, exportable output, and evidence from the assessment layer.

Workspace

Define the browser workspace contract.

Real project files, real environments, explicit status, and a clean path to owned code.

Owned artifacts

The output should be yours.

Repo ownership, export status, and deployment metadata are the product contract, not decoration.

Get early access

Assessments first

Reuse the evidence layer.

AFK can inherit files, AI modes, tests, prompt traces, and verification primitives from OA.

Assessment bridge

The builder gets stronger after OA is polished.

Candidate workspaces already need controlled files, AI-mode policy, tests, replayable evidence, and recruiter review. AFK should reuse that foundation instead of inventing a separate toy environment.

Product Card - Design to Spec

Candidates work in one controlled browser tab with tests, AI mode controls, and replayable evidence.

Same model access, visible prompts, and clear human ownership.

Learning bridge

Plain-English builders need a place to ship.

Vibecoding Courses can graduate learners from commands into real project creation once the AFK workspace is ready to own files, tests, and deploy handoff.

Concept lane

AFK is first-class, even before it is finished.

The page should make the ambition legible: a zero-config AI workspace that outputs owned projects, not screenshots or locked-in artifacts.
