🦖 Skill Builder
[!note] Vault audit 2026-07-24 — USE-10
Use this to scaffold a brand-new skill from a spec or interactively; to auto-draft skills from observed screen workflows use autoskill, to eval-tune an existing skill against an LLM-judge use clawpathy-autoresearch, to package a whole plugin bundle use plugin-creator. Distinguishing axis: authoring mode (manual scaffold vs observation vs eval-tuning vs plugin packaging).
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
CLI Reference
python skills/skill-builder/skill_builder.py --input spec.json --output skills/my-skill/
python skills/skill-builder/skill_builder.py --interactive
python skills/skill-builder/skill_builder.py --demo --output /tmp/skill_builder_demo
python skills/skill-builder/skill_builder.py --validate-only --input skills/my-skill/SKILL.md
python skills/skill-builder/skill_builder.py --input spec.json --dry-run
python clawbio.py run skill-builder --demo
python clawbio.py run skill-builder --input spec.json
Demo
python clawbio.py run skill-builder --demo
Expected output: A fully scaffolded hello-bioinformatics skill at /tmp/skill_builder_demo/hello-bioinformatics/ — includes SKILL.md, hello_bioinformatics.py, tests/test_hello_bioinformatics.py, and a result.json + report.md in the skill-builder output directory documenting what was created.
Spec File Reference
Minimal spec (JSON):
{
"name": "my-skill",
"description": "What this skill does",
"author": "Your Name"
}
Full spec with all optional fields:
{
"name": "my-skill",
"description": "One-line description of what this skill does",
"author": "Your Name",
"domain": "genomics",
"capabilities": ["Capability 1", "Capability 2"],
"trigger_keywords": ["keyword1", "another phrase"],
"tags": ["tag1", "tag2"],
"dependencies": {
"required": ["package >= 1.0"],
"optional": ["package2"]
},

Algorithm / Methodology
- Parse spec: Load JSON (stdlib) or YAML (pyyaml if available); fall back to interactive prompts
- Normalise name: Enforce lowercase-hyphen naming (
vcf-annotator, not VCF_Annotator)
- Fill defaults: domain → "bioinformatics", version → "0.1.0", capabilities/triggers → generic placeholders
- Render SKILL.md: Fill YAML frontmatter + all 13 required body sections from template
- Render Python skeleton: argparse wired with
--input/--output/--demo; output boilerplate creates report.md, result.json, reproducibility bundle
- Render test skeleton: pytest fixture + 3 standard tests (demo runs, report generated, result.json valid)
- Validate: Run the 13-item CONTRIBUTING checklist against the generated SKILL.md before writing
- Register: Append catalog entry; patch
clawbio.py SKILLS dict via targeted string replacement
Example Queries
- "Create a new skill called vcf-annotator that annotates VCF files with ClinVar"
- "Scaffold a skill for running PLINK GWAS pipelines"
- "Build a skill template for GO enrichment analysis"
- "Validate my SKILL.md before I submit a PR"
Output Structure
output_directory/
├── report.md # Summary of what was generated
├── result.json # Machine-readable scaffold manifest
└── reproducibility/
└── commands.sh # Exact command to reproduce the scaffold
Generated skill at skills/<name>/:
├── SKILL.md # Complete skill definition
├── <name>.py # Python skeleton with --input/--output/--demo
├── tests/
│ └── test_<name>.py # pytest skeleton with 3 standard tests
└── examples/
└── example_spec.json # The spec that generated this skill
Dependencies
Required (stdlib only — zero install):
- Python 3.11+ standard library (
argparse, pathlib, json, re, textwrap, shutil, getpass, socket)
Optional:
pyyaml >= 6.0 — enables YAML spec files in addition to JSON; graceful fallback to JSON-only mode if absent
Safety
- Local-first: No network calls; all generation is offline
- Non-destructive: Never overwrites existing files without
--force; prompts or errors if destination exists
- No hallucinated science: All generated SKILL.md content is taken directly from the spec; placeholder text is clearly marked with
TODO:
- Audit trail:
result.json and commands.sh record exactly what was generated and when
Integration with Bio Orchestrator
Trigger conditions — the orchestrator routes here when:
- User says "create a skill", "scaffold a skill", "new skill", "build a skill", "add a skill"
- User provides a JSON/YAML file with
name, description, author fields and asks to build a skill
Chaining partners:
bio-orchestrator: Skill builder output feeds back into the orchestrator once registered
