skillkit

name	skillkit
description	Toolkit for creating and validating skills and subagents. Use when: creating a new skill (fast or full mode), validating an existing skill, deciding Skills vs Subagents, migrating docs to skills, estimating token cost, or running a security scan. Triggers: "create skill", "build skill", "validate skill", "new subagent", "skills vs subagents", "estimate tokens", "security scan".
category	core

Section 1: Intent Detection & Routing

Detect user intent, route to appropriate workflow.

Intent	Keywords	Route To
Full skill creation	"create skill", "build skill", "new skill"	Section 2
Subagent creation	"create subagent", "build subagent", "new subagent"	Section 6
Validation	"validate", "check quality"	Section 3
Decision	"Skills vs Subagents", "decide", "which to use"	Section 4
Migration	"convert", "migrate doc"	Section 5
Single tool	"validate only", "estimate tokens", "scan"	Section 7

PROCEED to corresponding section after intent detection.

Stop Condition (Mandatory):

• If multiple routes match or intent is ambiguous: stop, ask user to choose one route.
• Do not proceed until user confirms the route.

Workflow Value: Research-driven approach validates design before building. Sequential steps with checkpoints produce 9.0/10+ quality vs ad-hoc creation.

Section 2: Creation Workflows (Dual Mode)

Prerequisites: Skill description provided, workspace available.

Mode Selection (Required at Start)

Detect or prompt for workflow mode before running the creation flow.

Stop Condition (Mandatory):

• If mode is not explicitly provided: stop and ask "Do you want fast or full mode?"
• Do not continue until user confirms the mode.

Mode	Steps	Validation	Quality Target	Time
fast	12	Structural only	>=9.0/10	<10 min
full	16	Structural + Behavioral	>=9.0/10 and behavioral >=7.0	<20 min

No implicit default mode is allowed when mode is not explicitly known.

Workflow A: Fast Mode (12 Steps)

Use when .skillkit-mode contains fast or marker does not exist.

→ READ references/section-2-fast-creation-workflow.md IN FULL before starting. Create a task for each step listed in that file, then follow them in order. The outline below is a summary only — the reference file is authoritative.

Phase 1: Decision & Research

• Step 0: Decide approach (decision_helper.py)
• Step 1: Research and proposals
• Step 2: User validation
• Stop Condition: Stop and request user approval before continuing to Step 3.

Phase 2: Creation

• Step 3: Initialize skill (init_skill.py --mode fast)
• Step 4: Create content

Phase 3: Structural Validation

• Step 5: Validate structure (validate_skill.py)
• Step 6: Security audit (security_scanner.py)
• Step 7: Token optimization (token_estimator.py)

Phase 4: Packaging

• Step 8: Progressive disclosure check
• Step 9: Generate tests (test_generator.py)
• Step 10: Quality assessment (quality_scorer.py)
• Step 11: Package (package_skill.py)

Workflow B: Full Mode (16 Steps)

Use when .skillkit-mode contains full.

→ READ references/section-2-full-creation-workflow.md IN FULL before starting. Create a task for each step listed in that file, then follow them in order. The outline below is a summary only — the reference file is authoritative.

Phase 1: Decision and Research

• Step 0: Decide approach (decision_helper.py)
• Step 1: Research and proposals
• Step 2: User validation
• Stop Condition: Stop and request user approval before continuing to Step 3.

Phase 2: Behavioral Baseline (extra vs fast)

• Step 3 (RED): Run pressure scenarios without skill → Load references/section-2-full-creation-workflow.md → section "Full Mode Behavioral Testing Protocol" (mandatory)
• Step 4: Document baseline failures

Phase 3: Creation

• Step 5: Initialize skill (init_skill.py --mode full)
• Step 6: Create content addressing baseline failures

Phase 4: Behavioral Verification (extra vs fast)

• Step 7 (GREEN): Run scenarios with skill → Load references/section-2-full-creation-workflow.md → section "Full Mode Behavioral Testing Protocol" (mandatory)
• Step 8: Fix gaps

Phase 5: Structural Validation

• Step 9: Validate structure
• Step 10: Security audit
• Step 11: Token optimization

Phase 6: Refinement (extra vs fast)

• Step 12 (REFACTOR): Combined pressure tests → Load references/section-2-full-creation-workflow.md → section "Full Mode Behavioral Testing Protocol" (mandatory)
• Step 13: Close loopholes

Phase 7: Packaging

• Step 14: Quality assessment (quality_scorer.py --format json) — behavioral score derived from Steps 3/7/12 subagent results, not from --behavioral flag
• Step 15: Package (package_skill.py)

Mode Detection

Priority order:

1. Explicit flag: --mode fast or --mode full
2. Skill marker: .skillkit-mode file content
3. If unknown: stop and ask user to choose fast or full

Section 3: Validation Workflow (Overview)

Use when: Validating existing skill

Steps: Execute validation subset (Steps 3-8)

1. Structure validation (validate_skill.py)
2. Security audit (security_scanner.py)
3. Token analysis (token_estimator.py)
4. Progressive disclosure check
5. Test generation (optional)
6. Quality assessment (quality_scorer.py)

For detailed workflow: See references/section-3-validation-workflow-existing-skill.md

---

Section 4: Decision Workflow (Overview)

Use when: Uncertain if Skills is right approach

CRITICAL: Agent MUST create a temp JSON file first. The decision_helper.py script does NOT accept inline JSON strings - it requires a file path to a JSON file.

Step-by-step invocation: See references/section-4-decision-workflow-skills-vs-subagents.md

Accuracy: Highest (90-95% confidence).

Process:

1. Run decision_helper.py with json file.
2. Answer interactive questions
3. Receive recommendation with confidence score
4. Proceed if Skills recommended (confidence >=75%)
5. If confidence <75% or recommendation is uncertain, stop and ask user whether to continue, switch route, or refine inputs.

For detailed workflow: See references/section-4-decision-workflow-skills-vs-subagents.md

---

Section 6: Subagent Creation Workflow (Overview)

Use when: Creating new subagent (user explicitly asks or decision workflow recommends)

Prerequisites: Role definition clear, workspace available Quality Target: Clear role, comprehensive workflow, testable examples Time: <15 min with template

8-Step Process:

STEP 0: Requirements & Role Definition

• Answer: Primary role? Trigger conditions? Tool requirements?
• Choose subagent_type from predefined list

STEP 1: Initialize Subagent File

• Tool: python scripts/init_subagent.py subagent-name --path ~/.claude/agents
• Creates: ~/.claude/agents/subagent-name.md with template
• Important: Subagents are individual .md files (not directories)
• Stop Condition: If target file already exists, stop and ask whether to overwrite, rename, or cancel.

STEP 2: Define Configuration

• Edit YAML frontmatter (name, description, type, tools, skills)
• Configure tool permissions (minimal but sufficient)

STEP 3: Define Role and Workflow

• Role definition section
• Trigger conditions (when to invoke)
• Multi-phase workflow

STEP 4: Define Response Format

• Output structure template
• Tone and style guidelines
• Error handling

STEP 5: Add Examples

• At least 1 complete example
• Input/Process/Output format

STEP 6: Validation

• YAML validity check
• Structure verification
• Completeness review

STEP 7: Testing

• Test invocation with Task tool
• Iterate based on results

STEP 8: Documentation & Deployment

• Create README.md
• Register in system
• Stop Condition: Ask for explicit user confirmation before register/deploy actions.

For detailed workflow: See references/section-6-subagent-creation-workflow.md

Section 5: Migration Workflow (Overview)

Use when: Converting document to skill

Process:

1. Decision check (Step 0)
2. Migration analysis (migration_helper.py)
3. Structure creation
4. Execute validation steps (3-8)
5. Package (Step 9)

Stop Condition (Mandatory):

• Before structure creation or any write/overwrite operation: ask user confirmation.
• Do not modify files until user confirms.

For detailed workflow: See references/section-5-migration-workflow-doc-to-skill.md

Guide: references/section-6-subagent-creation-workflow.md

Tool Output Standardization (v1.0.1+)

All 9 tools support --format json. Text mode still available via --format text (backward compatible). decision_helper defaults to JSON for automation.

JSON Output Structure:

{
  "status": "success" | "error",
  "tool": "tool_name",
  "timestamp": "ISO-8601",
  "data": { /* tool-specific results */ }
}

Quality Assurance Enhancements (v1.2+)

File & Reference Validation:

• validate_skill.py now comprehensively checks file references (markdown links, code refs, path patterns)
• package_skill.py validates references before packaging, detects orphaned files
• Prevents broken references and incomplete files in deployed skills

Content Budget Enforcement (v1.2+):

• Hard limits on file size: P0 ≤150 lines, P1 ≤100 lines, P2 ≤60 lines
• Real-time token counting with progress indicators
• Prevents file bloat that previously caused 4-9x target overruns

Execution Planning (v1.2+):

• P0/P1/P2 prioritization prevents over-scoping
• Token budget allocated per file to maintain efficiency
• Research phase respects Verbalized Sampling probability thresholds (p>0.10)

Quality Scorer Context:

• Scores calibrated for general skill quality heuristics
• Target: 70%+ is good, 80%+ is excellent
• Style scoring may not fit all skill types (educational vs technical)
• Use as guidance, supplement with manual review for edge cases

Section 8: Mode Selection Guide

Skill Type	Recommended Mode	Why
TDD or discipline skill	full	must resist rationalization under pressure
Code pattern skill	fast	structural checks are usually sufficient
API reference skill	fast	primarily retrieval accuracy
Workflow orchestration skill	full	complex flow benefits from pressure checks
Debugging technique skill	fast	concise technique with clear method

Full mode adds behavioral testing (pressure scenarios). Use it when discipline enforcement is core to the skill's purpose.
