Add load_public_skills() to load skills from public registry

[xingyaoww]

Overview

This PR adds a new load_public_skills() function that fetches and loads skills from the OpenHands/skills public repository. This allows users to get the latest community skills without waiting for SDK updates.

Related to:

• Skills repository PR: Add public skills from OpenHands repository skills#1
• Issue: Migrate skill library to SDK and enable automatic loading #1219

Changes

Core Functionality

• New load_public_skills() function in skill.py:
  • Fetches skill files from GitHub using the GitHub API
  • Downloads and loads skills dynamically
  • Handles errors gracefully (HTTP errors, network errors, invalid skills)
  • Supports custom repository URLs and branches for flexibility

AgentContext Integration

• Add load_public_skills boolean field to AgentContext
• Add _load_public_skills validator to automatically load public skills when enabled
• Merge public skills with explicit skills, avoiding duplicates
• Explicit skills take precedence over public skills

API Export

• Export load_public_skills from skills.__init__ module for easy access

Testing

• Comprehensive test coverage in test_load_public_skills.py:
  • Test successful loading from repository
  • Test HTTP and network error handling
  • Test custom repositories and branches
  • Test invalid skill handling
  • Test AgentContext integration
  • Test skill precedence and merging
  • All 11 new tests passing

Usage Examples

Loading public skills directly

from openhands.sdk.context.skills import load_public_skills

# Load skills from the official repository
public_skills = load_public_skills()

# Or from a custom repository
custom_skills = load_public_skills(
    repo_url="https://github.com/my-org/my-skills",
    branch="develop"
)

Using with AgentContext

from openhands.sdk.context import AgentContext

# Automatically load public skills
context = AgentContext(load_public_skills=True)

# Or combine with user skills
context = AgentContext(
    load_user_skills=True,
    load_public_skills=True
)

Benefits

1. Latest Skills: Users get the latest community skills without SDK updates
2. Flexibility: Serves skills independently from SDK releases
3. Community: Easier for the community to contribute and use shared skills
4. Backward Compatible: All existing functionality remains unchanged

Testing

All tests pass:

uv run pytest tests/sdk/context/skill/test_load_public_skills.py -v

All skill-related tests pass:

uv run pytest tests/sdk/context/skill/ -v

With the current implementation, skill data is fetched remotely from GitHub every time the application starts. As the skill library grows larger, this will incur considerable overhead. I'm wondering if we could add a local cache directory to address this. WDYT

[xingyaoww]

@OpenHands please review diff against main for this PR, and implement this: #1248 (comment)

We should maintain a git repo locally and try to pull it to make sure it stays up-to-date everytime we launch it

Perfect! The changes have been pushed. Let me provide a final summary:

Summary

I've successfully implemented the requested change from PR #1248 comment. The implementation now uses git-based caching instead of fetching individual files via HTTP on every launch.

Changes Made

1. Core Implementation (skill.py):

• Added _get_skills_cache_dir() - Creates/returns cache directory at ~/.openhands/skills-cache/
• Added _update_skills_repository() - Clones or updates the local git repository:
  • First run: Clones repository with --depth 1 for efficiency
  • Subsequent runs: Fetches and resets to latest changes using git fetch + git reset --hard
  • Network failures: Gracefully falls back to existing cached version
• Modified load_public_skills() - Loads skills from local git clone instead of HTTP

2. Test Suite (test_load_public_skills.py):

• Completely rewrote all 14 tests to mock git operations instead of HTTP calls
• Added tests for:
  • Repository cloning and updating
  • Timeout handling
  • Fallback to cache when updates fail
  • All AgentContext integration scenarios

Benefits

✅ More Efficient: Only fetches changed files (git is optimized for incremental updates)
✅ Scales Better: As skill library grows, git pull is much faster than fetching individual files
✅ Offline Support: Works offline after initial clone
✅ Reliable: Automatic fallback to cache if network issues occur
✅ Follows Best Practices: Standard approach for dependency management

Test Results

All 51 skill-related tests pass successfully. The implementation is backward compatible and doesn't break any existing functionality.

The changes have been committed and pushed to the add-load-public-skills branch, updating PR #1248.

Summary

I've successfully completed your request to review the updated example and update the documentation for the load_public_skills feature.

Work Completed

1. Reviewed the Updated Example

Examined examples/01_standalone_sdk/03_activate_skill.py in PR #1248, which now includes:

• load_public_skills=True in AgentContext
• A test case demonstrating the 'github' public skill
• Comprehensive comments explaining AgentContext capabilities

2. Created Documentation PR

Repository: OpenHands/docs
Branch: add-load-public-skills
PR: OpenHands/docs#133 (draft)
File Updated: sdk/guides/skill.mdx

3. Documentation Changes

Updated the skill guide with:

Synced Example Code

• Updated to match the latest version from the SDK repository
• Fixed model name and added all new comments and features

New Section: "Loading Public Skills"

Added comprehensive documentation with four subsections:

1. Automatic Loading via AgentContext - How to enable load_public_skills=True and what happens automatically
2. Programmatic Loading - Manual loading with load_public_skills() function for more control
3. Custom Skills Repository - Support for loading from custom repositories with custom branches
4. How It Works - Detailed explanation of the git-based caching mechanism (~/.openhands/cache/skills/)

Also documented:

• Skill precedence rules (explicit skills override public skills)
• Link to explore the public skills repository
• Offline mode fallback behavior

PRs Cross-Referenced

• SDK PR: Add load_public_skills() to load skills from public registry #1248
• Docs PR: Document load_public_skills feature docs#133

Both PRs are on the same branch name (add-load-public-skills) for easy tracking. The documentation PR should be reviewed and merged after the SDK PR is merged to maintain consistency.

I've successfully fixed the failing tests! Here's a summary of the changes:

Summary

Problem: Two tests were failing in test_load_public_skills.py:

• test_update_skills_repository_update_existing
• test_update_skills_repository_update_fails_uses_cache

Root Cause: The tests were creating a directory named "openhands-skills" but the implementation in skill.py uses "public-skills" as the repository directory name (line 404). This mismatch caused assertion failures where the expected path didn't match the actual returned path.

Solution: Updated both tests to use "public-skills" instead of "openhands-skills" to match the implementation.

Changes Made:

• Line 206: Changed repo_path = cache_dir / "openhands-skills" → repo_path = cache_dir / "public-skills"
• Line 258: Changed repo_path = cache_dir / "openhands-skills" → repo_path = cache_dir / "public-skills"

Verification:
✅ Both previously failing tests now pass
✅ All 14 tests in test_load_public_skills.py pass
✅ Pre-commit hooks pass (Ruff format, Ruff lint, pycodestyle, pyright, import checks)
✅ Changes committed and pushed to branch add-load-public-skills

The fix is minimal and focused—only the directory names in the test assertions were changed to match the implementation's behavior.
