AlphaOne Harness
A workspace-aware AI coding workbench designed to understand projects, prepare implementation plans, edit source code, build and test, diagnose failures, repair and re-validate changes, review AI edits, and finish with an evidence-grounded work result.
From Workspace Understanding to Reviewed Results
AlphaOne Harness combines a familiar development workbench with a governed AI Agent workflow. The application owns the coding experience; AlphaOne HyperRouter owns model connectivity, provider routing, Local AI, quota handling, and Auto RollOver.
Core AlphaOne Harness Features
These capabilities are part of the completed AOH Release Candidate path. Future roadmap items are shown separately below.
Workspace & Project Intelligence
Discover project structure, resolve the relevant project or module, locate likely source files, and choose appropriate build/test targets without requiring the user to provide every exact path.
Implementation Plan & Progress
Present implementation plans for review, accept multiple feedback items, request revisions, authorize implementation, and surface structured progress during the Agent lifecycle.
Integrated Code Editing
Multi-document editor, workspace Explorer, file lifecycle, Find/Replace, save protection, source selections, and AI actions including Explain, Fix, Improve, and Ask.
Build / Test / Diagnose / Fix
Run project-aware build and test operations, inspect structured diagnostics and raw output, repair failures, rebuild, and re-test with bounded validation behavior.
AI Diff Review
Review tracked Agent changes in the workbench with file and hunk-level controls, including explicit Accept and safe Reject workflows before changes are considered approved.
Checkpoints, Undo & Redo
Agent checkpoints and restoration workflows let users undo an Agent run, restore earlier checkpoint state, and redo supported restored work while preserving review history.
Terminal, Output & Problems
Integrated interactive terminal plus Output channels, Problems aggregation, build/test diagnostics, logs, and developer-facing execution evidence.
Approval & Sandbox Controls
Govern Agent operations through centralized approval and permission policy while retaining sandbox and tool-execution boundaries as authoritative controls.
Dynamic Tool Exposure
Expose only the tool capability groups relevant to the current Agent step where safely possible, with conservative expansion and a full-capability fallback when needed.
Final Walkthrough
Produce a grounded work-result artifact that distinguishes what was implemented, validated, reviewed, inferred, skipped, or still unresolved.
Workspace Search & Replace
Search across the workspace, preview replacement plans, and apply controlled replacements while preserving editor and workspace safety boundaries.
Governed Web Search & Fetch
AOH-owned web search and bounded web fetch are available under Network & Send Data approval policy, separate from HyperRouter's model-routing responsibility.
A Complete Agentic Development Workflow
The Release Candidate gate validates an end-to-end workflow rather than isolated chat features.
One Workbench. Multi-Provider Intelligence.
AOH does not expose alternative direct model backends. HyperRouter is the fixed AI connectivity layer, while remaining a separate product that can also be used by compatible IDEs and coding clients.
Auto RollOver
When an eligible upstream attempt fails before downstream output is committed, HyperRouter can continue through its configured provider routing and fallback policy without requiring AOH to switch backend configuration.
Local & Cloud AI
HyperRouter can provide AOH with Local Device GGUF, user-owned Local Cloud, Direct BYOK cloud providers, and its configured fallback cascade through one stable AOH backend identity.
Agentic Continuity Backend
HyperRouter normalizes supported protocol and tool traffic and maintains portable canonical history so compatible Agent workflows can retain usable context across eligible provider changes.
Provider Configuration Stays in HyperRouter
API keys, physical provider/model selection, routing priority, Local AI configuration, quota handling, and provider-specific compatibility remain owned by HyperRouter rather than duplicated inside AOH.
Review AI Work Before You Accept It
AlphaOne Harness is designed around governed Agent execution rather than silent source mutation. Implementation plans can be reviewed, sensitive tool operations remain subject to policy, tracked Agent changes enter AI Diff Review, and the user retains explicit Accept/Reject authority.
What Comes After the Release Candidate
The following phases are planned post-RC capability expansions. They are not presented as current Release Candidate features.
Universal Content Reading & Document Intelligence
Extend bounded reading and provenance-aware extraction to common engineering and business document formats without expanding write authority.
POST-RC / PLANNEDWorkspace Knowledge / RAG
Add persistent, incremental workspace retrieval for large repositories and document-heavy workspaces while keeping current source and session evidence authoritative.
POST-RC / PLANNEDFull Source Control / Git
Expand the current Git foundation with richer changes/diff, stage/unstage, commit, branch, history, stash, pull/push, and AI-assisted source-control workflows.
POST-RC / PLANNEDLSP / Code Intelligence
Add Language Server Protocol intelligence including diagnostics, symbols, definitions, references, rename, completion, hover, and code actions.
POST-RC / PLANNEDAdvanced Agent Platform
Expand Agent Profiles, tool sets, permission profiles, Agent handoff, Skills management, and MCP management using the existing runtime where appropriate.
POST-RC / PLANNEDTasks, Test Explorer & Debugging
Add richer task/run workflows, Test Explorer, debugger foundation, breakpoints, watch, call-stack, and related execution tooling.
POST-RC / PLANNEDAOH Setup Handles the HyperRouter Prerequisite
AlphaOne Harness and HyperRouter remain separate installed products. AOH Setup checks the installed HyperRouter version and installs or upgrades the bundled compatible prerequisite when required, while preserving the same or newer compatible installation.
