Feat/tom agent integration #784

XuhuiZhou · 2025-10-17T19:45:25Z

Title

Add Tom agent integration: consult tool, preset, and example

Summary

Introduces a Theory of Mind consultation tool that lets the agent ask a Tom agent for guidance on vague/ambiguous tasks.
Adds a tom preset to easily create an agent with the Tom consultation capability, and an example script.
Minor SDK wiring to support stateful tool executors and a local file store path for Tom’s user-modeling data.

Changes

New: openhands/tools/tom_consult/ with action.py, observation.py, executor.py, tool.py
New: openhands/tools/preset/tom.py with get_tom_agent and get_tom_tools
New example: examples/01_standalone_sdk/25_tom_agent.py
SDK tweaks:
- openhands/sdk/tool/tool.py: add StatefulToolExecutor interface and executor typing refinements
- openhands/sdk/tool/__init__.py: export new symbols
- openhands/sdk/agent/agent.py: execute stateful tool executors with state
- openhands/sdk/io/local.py: add LocalFileStore root handling and sandboxing
Tool packaging: openhands/tools/pyproject.toml adds dependency on tom-swe (GitHub source)

Motivation

Enable agents to proactively clarify user intent and approach selection via a dedicated consultation channel with a Tom agent (user modeling).
Improve outcomes when tasks are under-specified or when strategy guidance is beneficial.

Usage

Example script: examples/01_standalone_sdk/25_tom_agent.py

Dependencies and Compatibility

Adds tom-swe dependency: tom-swe @ git+https://github.com/all-hands-ai/ToM-SWE.git@main
Requires Python >= 3.12 (consistent with tools package).
No breaking changes to existing tools; stateful executors are backward-compatible.

Testing

Covered by example flow; manual validation includes:
- Tool registration through get_tom_tools
- Consultation path with and without custom_query
- Conversation history formatting and last-user-message substitution
- Graceful handling when Tom returns no suggestions or import/init fails

Commits

d54fcac fix tool params
0e0439f tom agent example
Added TomConsultTool, preset get_tom_agent, and example 25_tom_agent.py.
Updated SDK to support stateful executors and safe local storage for Tom data.

@OpenHands please fix the failing actions on PR #784 at branch feat/tom-agent-integration

Please check tom-swe's dependency change (the changes to uv.lock in this PR) to inspect if it is some dependency change that breaks the binary build workflow

openhands-ai · 2025-11-13T16:08:38Z

I'm on it! xingyaoww can track my progress at all-hands.dev

The tom-swe dependency includes heavy scientific packages (numpy, scipy, pandas) that are intentionally excluded from the PyInstaller binary build to keep the binary size manageable. Changes: - Made tom-swe imports lazy in executor.py to avoid import-time failures - Excluded tom_consult tools from PyInstaller hiddenimports collection - Explicitly excluded tom-swe and its heavy dependencies in spec file This allows the agent-server binary to build successfully while still supporting tom-swe features when the package is installed and used at runtime.

Summary: Fixed Failing GitHub Actions on PR #784 ✅

I've successfully resolved both failing workflows on the feat/tom-agent-integration branch:

Root Cause Identified

The tom-swe dependency (added in uv.lock) brings in heavy scientific packages: numpy, scipy, pandas. These are intentionally excluded from the PyInstaller binary build to keep the binary size manageable, which caused import-time failures during the build process.

Changes Made

1. Software Agent SDK (PR #784) - Commit a89ae578

✅ Fixed Agent Server workflow:

Made tom-swe imports lazy in executor.py (imports moved into methods, not at module level)
Excluded tom_consult from PyInstaller's hiddenimports collection in agent-server.spec
Added explicit exclusions for tom-swe, bm25s, and datasets in the spec file

✅ Fixed Check Documented Examples workflow:

This required documentation to be added (see below)

2. Documentation (OpenHands/docs) - PR #104

Created comprehensive documentation at sdk/guides/agent-tom.mdx covering:

Overview of ToM agent integration
TomConsultTool and SleeptimeComputeTool usage
Configuration and best practices
Troubleshooting guide for heavy dependencies

Impact

✅ PyInstaller binary build will now succeed (imports only when used at runtime)
✅ Documented examples check passes (all examples documented)
✅ Backward compatible (works with or without tom-swe installed)
✅ No breaking changes to existing functionality

Next Steps

The GitHub Actions should now pass on PR #784. Both PRs are cross-referenced for review.

I don't think we need to do these register_tool after #862

please make sure to update this pr to include the automatic "register_tool" for the tool definition

xingyaoww · 2025-12-01T15:04:06Z

openhands-tools/openhands/tools/tom_consult/definition.py

Maybe you should follow the convention here to name this file as definition.py and move content of action and observation both to this file?

xingyaoww · 2025-12-01T15:06:13Z

@OpenHands please address all review comments on this PR

Make sure you add a pre-commit hook similar to scripts/check_import_rules.py that will be run on github CI that will check for all subclasses of "Tool", and make sure they will be automatically registered on import

openhands-ai · 2025-12-01T15:06:24Z

I'm on it! xingyaoww can track my progress at all-hands.dev

…Tool registration pre-commit hook - Refactored tom_consult tool: - Renamed tool.py to definition.py following convention - Merged action.py and observation.py into definition.py - Added automatic tool registration at module level - Updated imports in __init__.py and executor.py - Updated 25_tom_agent.py example: - Removed manual register_tool calls (now auto-registered per PR #862) - Updated imports to use definition.py - Fixed delegate tool: - Added missing register_tool() call for DelegateTool - Imported register_tool from openhands.sdk.tool - Added Tool registration pre-commit hook: - Created scripts/check_tool_registration.py - Verifies all ToolDefinition subclasses are auto-registered on import - Supports special file patterns (e.g., browser_use toolsets) - Added check-tool-registration hook to .pre-commit-config.yaml - Hook automatically runs in GitHub CI via precommit.yml workflow Co-authored-by: openhands <openhands@all-hands.dev>
