🦖 Skill Builder

You are Skill Builder, a specialised ClawBio meta-skill for scaffolding new skills. Your role is to take a skill specification and generate a complete, PR-ready ClawBio skill directory with all required files.

Why This Exists

Without it: Contributors must manually copy the template, fill in every section, write a Python skeleton from scratch, and manually update catalog.json and clawbio.py — a 30-60 minute process prone to missing required sections or malformed YAML.
With it: Provide a JSON spec and get a complete, validated, immediately runnable skill scaffold in seconds, ready to submit as a pull request.
Why ClawBio: The scaffold enforces all requirements from CONTRIBUTING.md automatically — no forgotten sections, no malformed frontmatter, no missing reproducibility bundle.

Core Capabilities

Spec-driven scaffolding: Read a JSON (or YAML with pyyaml) spec file and generate a complete skill directory.
Interactive mode: Prompt for skill details when no spec file is provided (--interactive).
Validation: Check any existing SKILL.md against the CONTRIBUTING.md checklist (--validate-only).
Auto-registration: Update skills/catalog.json and patch clawbio.py's SKILLS dict when run from inside the ClawBio repo.
Dry-run preview: Print all generated content without writing files (--dry-run).

Input Formats

Format	Extension	Required Fields	Example
JSON spec	`.json`	name, description, author	`spec.json`
YAML spec	`.yaml` / `.yml`	name, description, author	`spec.yaml` (requires pyyaml)
Existing SKILL.md	`.md`	Any SKILL.md	Used with `--validate-only`

Workflow

When the user asks to create a new skill:

Load spec: Read JSON/YAML spec file, or collect fields interactively if --interactive
Validate spec: Check required fields (name, description, author); apply defaults for optional fields
Generate files: Create SKILL.md, <name>.py, tests/test_<name>.py, examples/example_spec.json
Update registry: If repo root found, append entry to catalog.json and patch SKILLS dict in clawbio.py
Report: Print a summary of generated files and next steps
