Skillforge

SkillForge 4.0 - Intelligent Skill Router & Creator

Analyzes ANY input to find, improve, or create the right skill.

Quick Start

Any input works. SkillForge will intelligently route to the right action:

# These all work - SkillForge figures out what you need:

SkillForge: create a skill for automated code review
→ Creates new skill (after checking no duplicates exist)

help me debug this TypeError
→ Recommends ErrorExplainer skill (existing)

improve the testgen skill to handle React components better
→ Enters improvement mode for TestGen

do I have a skill for database migrations?
→ Recommends DBSchema, database-migration skills

TypeError: Cannot read property 'map' of undefined
→ Routes to debugging skills (error detected)

Triggers

Creation Triggers

• SkillForge: {goal} - Full autonomous skill creation
• create skill - Natural language activation
• design skill for {purpose} - Purpose-first creation
• ultimate skill - Emphasize maximum quality
• skillforge --plan-only - Generate specification without execution

Routing Triggers (NEW in v4.0)

• {any input} - Analyzes and routes automatically
• do I have a skill for - Searches existing skills
• which skill / what skill - Recommends matching skills
• improve {skill-name} skill - Enters improvement mode
• help me with / I need to - Detects task and routes

Production-Ready Agentic Skill

Key principles:

• Phase 0 prevents duplicates - Always checks existing skills first
• Evolution/timelessness is the core lens (score ≥ 7 required)
• Every decision includes WHY
• Zero tolerance for errors
• Autonomous execution at maximum depth
• Scripts enable self-verification and agentic operation

Commands

Phase 0: Skill Triage (NEW in v4.0)

Before creating anything, SkillForge intelligently analyzes your input to determine the best action.

Decision Actions

Triage Script

# Run triage on any input
python scripts/triage_skill_request.py "help me debug this error"

# JSON output for automation
python scripts/triage_skill_request.py "create a skill for payments" --json

# Examples:
python scripts/triage_skill_request.py "TypeError: Cannot read property 'map'"
# → USE_EXISTING: Recommends ErrorExplainer (92%)

python scripts/triage_skill_request.py "create a skill for code review"
# → CLARIFY: CodeReview skill exists (85%), create anyway?

python scripts/triage_skill_request.py "help me with API and auth and testing"
# → COMPOSE: Multi-domain, suggests APIDesign + AuthSystem + TestGen chain

Ecosystem Index

Phase 0 uses a pre-built index of all skills:

# Rebuild skill index (run periodically or after installing new skills)
python scripts/discover_skills.py

# Index location: ~/.cache/skillrecommender/skill_index.json
# Scans: ~/.claude/skills/, plugins/marketplaces/*, plugins/cache/*

Integration with Phases 1-4

• USE_EXISTING: Exits early, no creation needed
• IMPROVE_EXISTING: Loads existing skill → Phase 1 analyzes gaps → Phase 2-4 enhance
• CREATE_NEW: Full pipeline (Phase 1 → 2 → 3 → 4)
• COMPOSE: Suggests using SkillComposer instead
• CLARIFY: Pauses for user input before proceeding

Validation & Packaging

Before distribution, validate your skill:

# Quick validation (required for packaging)
python scripts/quick_validate.py ~/.claude/skills/my-skill/

# Full structural validation
python scripts/validate-skill.py ~/.claude/skills/my-skill/

# Package for distribution
python scripts/package_skill.py ~/.claude/skills/my-skill/ ./dist

Frontmatter Requirements

Skills must use only these allowed frontmatter properties:

---
name: my-skill
description: What this skill does
license: MIT
metadata:
  version: 1.0.0
  model: claude-opus-4-5-20251101

└─────────────────────────────────────────────────────────┘

Check for overlap with existing skills:

ls ~/.claude/skills/
# Grep for similar triggers in existing SKILL.md files

1B: Multi-Lens Analysis

Apply all 11 thinking models systematically:

Minimum requirement: All 11 lenses scanned, at least 5 applied in depth.

See: references/multi-lens-framework.md

1C: Regression Questioning

Iterative self-questioning until no new insights emerge:

ROUND N:
│
├── "What am I missing?"
├── "What would an expert in {domain} add?"
├── "What would make this fail?"
├── "What will this look like in 2 years?"
├── "What's the weakest part of this design?"
└── "Which thinking model haven't I applied?"
    │
    └── New insights > 0?
        │
        ├── YES → Incorporate and loop
        └── NO → Check termination criteria

Termination Criteria:

• Three consecutive rounds produce no new insights
• All 11 thinking models have been applied
• At least 3 simulated expert perspectives considered
• Evolution/timelessness explicitly evaluated
• Automation opportunities identified

See: references/regression-questions.md

1D: Automation Analysis

Identify opportunities for scripts that enable agentic operation:

FOR EACH operation in the skill:
│
├── Is this operation repeatable?
│   └── YES → Consider generation script
│
├── Does this produce verifiable output?
│   └── YES → Consider validation script
│
├── Does this need state across sessions?
│   └── YES → Consider state management script
│
├── Does this involve external tools?
│   └── YES → Consider integration script
│
└── Can Claude verify success autonomously?
    └── NO → Add self-verification script

Automation Lens Questions:

Decision: Script vs No Script

See: references/script-integration-framework.md

Specification Structure

The specification captures all analysis insights in XML format:

See: references/specification-template.md

Specification Validation

Before proceeding to Phase 3:

• All sections present with no placeholders
• Every decision includes WHY
• Timelessness score ≥ 7 with justification
• At least 2 extension points documented
• All requirements traceable to source
• Scripts section complete (if applicable)
• Agentic capabilities documented (if scripts present)

Context: Fresh, clean (no analysis artifacts polluting) Standard: Zero errors—every section verified before proceeding

Generation Order

1. Create directory structure
   mkdir -p ~/.claude/skills/{skill-name}/references
   mkdir -p ~/.claude/skills/{skill-name}/assets/templates
   mkdir -p ~/.claude/skills/{skill-name}/scripts  # if scripts needed

2. Write SKILL.md
   • Frontmatter (YAML - allowed properties only)
   • Title and brief intro
   • Quick Start section
   • Triggers (3-5 varied phrases)
   • Quick Reference table
   • How It Works overview
   • Commands
   • Scripts section (if applicable)
   • Validation section
   • Anti-Patterns
   • Verification criteria
   • Deep Dive sections (in <details> tags)

3. Generate reference documents (if needed)
   • Deep documentation for complex topics
   • Templates for generated artifacts
   • Checklists for validation

4. Create assets (if needed)
   • Templates for skill outputs

5. Create scripts (if needed)
   • Use script-template.py as base
   • Include Result dataclass pattern
   • Add self-verification
   • Document exit codes
   • Test before finalizing

Quality Checks During Generation

Panel: 3-4 Opus agents with distinct evaluative lenses Requirement: Unanimous approval (all agents) Fallback: Return to Phase 1 with feedback (max 5 iterations)

Panel Composition

Script Agent (Conditional)

The Script Agent is activated when the skill includes a scripts/ directory. Focus areas:

Script Agent Scoring:

Agent Evaluation

Each agent produces:

## [Agent] Review

### Verdict: APPROVED / CHANGES_REQUIRED

### Scores
| Criterion | Score (1-10) | Notes |
|-----------|--------------|-------|

### Strengths
1. [Specific with evidence]

### Issues (if CHANGES_REQUIRED)
| Issue | Severity | Required Change |
|-------|----------|-----------------|

### Recommendations
1. [Even if approved]

Consensus Protocol

IF all agents APPROVED (3/3 or 4/4):
    → Finalize skill
    → Run validate-skill.py
    → Update registry
    → Complete

ELSE:
    → Collect all issues (including script issues)
    → Return to Phase 1 with issues as input
    → Re-apply targeted questioning
    → Regenerate skill and scripts
    → Re-submit to panel

IF 5 iterations without consensus:
    → Flag for human review
    → Present all agent perspectives
    → User makes final decision

See: references/synthesis-protocol.md

Every skill is evaluated through the evolution lens:

Temporal Projection

Timelessness Scoring

Requirement: All skills must score ≥7.

Anti-Obsolescence Patterns

See: references/evolution-scoring.md
