Change Description

Implements four Claude Code skills (reusable task patterns) to provide structured guidance for common Hyrax development workflows. Addresses feedback from PRs #656 and #635 that robots were getting "bogged down with the amount of dev tooling" and that "many of these sections feel like they should be claude skills."

Solution Description

Claude Skills Created

Four Markdown skills in .github/skills/:

  • hyrax-development-workflow.md (142 lines) - Setup → code → test → commit workflow, timeout expectations, network retry strategies
  • hyrax-testing-strategy.md (303 lines) - pytest markers (slow/fast), parallel execution, fixtures, debugging patterns, hardware warnings
  • adding-hyrax-components.md (495 lines) - Model/dataset/verb addition with decorators, registration patterns, simplified tabular dataset examples, optional metadata interface
  • hyrax-configuration-system.md (179 lines) - Configuration invariants, default requirements, key=false convention (correctly explained), immutability rules

Each skill provides:

  • YAML frontmatter with metadata (name, description, version, tags)
  • Concise, focused markdown instructions emphasizing key patterns and invariants
  • Simple, general code examples (tabular datasets, config-driven verbs)
  • Cross-references to related skills and documentation
  • Actionable guidance for discrete tasks

Skills follow standard practice from Claude Code and GitHub Copilot documentation using Markdown format with YAML frontmatter.

Key Design Decisions

Simplicity and Accuracy:

  • Dataset examples use simple tabular data (not image-specific) for broader applicability
  • Dataset example shows optional metadata interface using Astropy Table for visualization support
  • Verb examples emphasize configuration over CLI parameters
  • Configuration skill correctly explains key=false convention as Hyrax project pattern (TOML has no None syntax)
  • Configuration skill documents common codebase pattern: config['foo'] if config['foo'] != False else None
  • Removed out-of-scope sections (registration issues, external plugins)

Hardware Awareness:

  • Testing skill includes warnings about slow tests requiring beefy hardware
  • Clarifies GitHub Action runners will timeout on slow tests

Integration

  • Updated CLAUDE.md with skills section linking to all four skills
  • Created .github/skills/README.md explaining skill usage and structure
  • Skills are standard .md files that work with both Claude Code and GitHub Copilot

Rationale

Skills address specific pain points identified in feedback:

  • Prevent premature command cancellation (Development Workflow timeouts)
  • Reduce testing confusion (Testing Strategy markers, parallel execution, hardware requirements)
  • Ensure correct component patterns (Adding Components with simple, general examples and metadata interface)
  • Prevent config errors (Configuration System invariants, defaults, and correct key=false convention)

Code Quality

  • I have read the Contribution Guide and agree to the Code of Conduct
  • My code follows the code style of this project
  • My code builds (or compiles) cleanly without any errors or warnings
  • My code contains relevant comments and necessary documentation

Implement four Claude skills as requested:
1. Hyrax Development Workflow - setup, validation, timeouts
2. Hyrax Testing Strategy - pytest markers, fixtures, parallel execution
3. Adding Hyrax Components - models, datasets, verbs with decorators
4. Hyrax Configuration System - ConfigDict, defaults, immutability

Skills are JSON files in .github/skills/ with structured guidance.
Updated CLAUDE.md to reference the new skills.

The four JSON skill files were initially blocked by .gitignore's *.json pattern.
Force-adding them as they are configuration/documentation files, not data files.

Add exception to .gitignore's *.json pattern to allow tracking
.github/skills/*.json files, which are configuration/documentation

Please take these same skills and put them into .md files, removing the .json files.

Follow the standard practice in https://code.claude.com/docs/en/skills and https://docs.github.com/en/copilot/concepts/agents/about-agent-skills where all the skills are .md files

Following standard practice from Claude Code and GitHub Copilot documentation,
convert all skill files from .json to .md format with YAML frontmatter.

Changes:
- Convert 4 JSON skills to Markdown with YAML frontmatter
- Remove .json files
- Update CLAUDE.md links to reference .md files
- Update .github/skills/README.md to reflect Markdown format
- Revert .gitignore exception (no longer needed for .md files)

ConfigDict is internal to the config system, so it shouldn't really get created outside of there, which means this example and a lot of the others are wrong.

Overall make this much shorter emphasizing the invariants of the config system over precise usage

## The `key = false` Convention

**Convention**: `key = false` in TOML means the key is optional and evaluates to `None` in Python.
Copy link
Collaborator

Choose a reason for hiding this comment

The reason will be displayed to describe this comment to others. Learn more.

It doesn't evaluate to None in Python. We in the Hyrax project commonly use key=false in toml to mean key=None, because toml has no way to assign None to a key syntactically.

The common codebase pattern that creates this social convention is
foo_value = config['foo'] if config['foo'] != False else None

key=false in default TOML means the key is either:

  1. Required to run, and the user must supply it
  2. Optional, but the none value means something sensible (e.g. feature disabled)

## Best Practices

1. **Always provide defaults**: Every key must be in `hyrax_default_config.toml`
2. **Use `key = false` for optional features**: This clearly indicates optional parameters

Use key=false convention in situations where the config is required to be specified by the user, or where lacking the config overall has behavior that would make sense to the user.

@copilot Please edit these skills to address all unresolved comments

Configuration system (hyrax-configuration-system.md):
- Corrected key=false convention explanation - it represents None in Python
- Added common codebase pattern: config['foo'] != False check
- Clarified when to use key=false (required input or optional with None behavior)
- Updated best practices to reflect correct usage

Adding components (adding-hyrax-components.md):
- Removed optional sample_data() and is_map() methods from example
- Removed label handling from __getitem__ (not in minimal example)
- Added section on optional metadata interface with Astropy Table
- Shows how to pass metadata_table to super().__init__() for visualization
