Professional skill and subagent creation toolkit with dual-mode workflow (fast/full), behavioral validation, and quality gates for 9.0/10+ scores.
npx claudepluginhub rfxlamia/skillkitThe toolkit for creating reusable skills for AI coding agents.
SkillKit helps you build, validate, and share skills that extend how your AI agent works. Works with Claude Code, GitHub Copilot, OpenCode, and Codex.

SkillKit is a toolkit for creating and validating custom AI agent skills. It ships two core skills:
skillkit — meta-skill for creating new skills and subagents with dual-mode validationskillkit-help — pre-build orientation: understand what skills are, decide skills vs subagentsLooking for community skills & agents? Use:
npx @rfxlamia/sm→ SkillKit Marketplace
npx @rfxlamia/skillkit
Interactive CLI — pick your tool(s), choose user or project scope. Done.
| Skill | Trigger | What it does |
|---|---|---|
| skillkit | /skillkit | Create & validate skills/subagents — fast mode (12 steps) or full mode (15 steps) |
| skillkit-help | /skillkit-help | Answer "what are skills?", "should I make one?", "is my skill good enough?" |
npx @rfxlamia/skillkit/skillkit-help — guided path to your first skill in ~10 minutesThe skillkit skill drives the creation workflow:
| Trigger | Workflow | Steps |
|---|---|---|
create skill | Full skill creation | 12 steps with research + validation |
create subagent | Subagent creation | 8 steps with template-based workflow |
validate skill | Validation only | Structure, references, quality checks |
Skills vs Subagents | Decision helper | Recommends approach, then creates |
convert doc to skill | Migration | Transform existing docs into skills |
Quality target: 9.0+/10 via 5-layer validation and multi-proposal generation.
14 Python scripts in skills/skillkit/scripts/ — all support --format {text|json}.
| Script | Purpose |
|---|---|
init_skill.py | Initialize new skill directory structure |
init_subagent.py | Initialize new subagent with YAML template |
validate_skill.py | Structure and YAML validation |
token_estimator.py | Token consumption and cost estimation |
split_skill.py | Progressive disclosure auto-splitting |
pattern_detector.py | Workflow pattern recommendation |
pattern_detector_new.py | Enhanced pattern detection |
decision_helper.py | Skills vs Subagents decision tree |
security_scanner.py | Security vulnerability detection |
test_generator.py | Automated test generation |
quality_scorer.py | 5-category quality scoring (100 points) |
migration_helper.py | Document to skill conversion |
package_skill.py | Package skill for distribution |
quick_validate.py | Quick validation checks |

Professional skill and subagent creation with dual-mode workflow: 12-step fast mode and 15-step full mode with behavioral pressure testing and TDD integration.
Essential skills for everyday development: beginner-friendly explanations (baby-education), comprehensive README creation (readme-expert), LLM prompt optimization (prompt-engineering), AI-to-human doc transformation (humanize-docs), technical spec creation (quick-spec), pre-deployment QA checklisting (pre-deploy-checklist), and developer progress logging (been-there-done-that).
Agent capability frameworks: STAR framework for understanding implicit intent (framework-initiative), critical thinking architecture with reasoning selection (framework-critical-thinking), and adversarial review protocol with mandatory bug quota (adversarial-review). Build smarter, self-correcting agents and validate plans before execution.
Content creation powerhouse: viral thread generation (thread-pro), storytelling (storyteller), screenwriting (screenwriter), creative copywriting with databases (creative-copywriting), image prompt optimization (imagine), and high-diversity content generation (diverse-content-gen).
Specialized subagent collection: Creative copywriter with psychology triggers, SEO manager with proven formulas, decision-making agents (velocity-first Sam Altman, safety-first Dario Amodei), Kotlin expert, doc simplifier, and comprehensive red team security agent.
Professional skill creation with TDD workflow. Features dual-mode (fast/full), behavioral validation, and automated quality gates for 9.0/10+ scores.
