Execution Modes
Mode 1: Sequential (Fixed Order)
Traditional linear execution model, phases execute in numeric prefix order.
Phase 01 -> Phase 02 -> Phase 03 -> ... -> Phase N
Use Cases:
- Pipeline tasks (collect -> analyze -> generate)
- Strong dependencies between phases
- Fixed output structure
Examples: software-manual, copyright-docs
Mode 2: Autonomous (Stateless Auto-Select)
Intelligent routing model, dynamically selects execution path based on context.
---------------------------------------------------
Orchestrator Agent
(Read state -> Select Phase -> Execute -> Update)
---------------------------------------------------

---------+----------+----------

Phase A Phase B Phase C
(standalone) (standalone) (standalone)
Use Cases:
- Interactive tasks (chat, Q&A)
- No strong dependencies between phases
- Dynamic user intent response required
Examples: issue-manage, workflow-debug
Key Design Principles
- Mode Awareness: Automatically recommend execution mode based on task characteristics
- Skeleton Generation: Generate complete directory structure and file skeletons
- Standards Compliance: Strictly follow
_shared/SKILL-DESIGN-SPEC.md
- Extensibility: Generated Skills are easy to extend and modify
Required Prerequisites
IMPORTANT: Before any generation operation, read the following specification documents. Generating without understanding these standards will result in non-conforming output.
Core Specifications (Mandatory Read)
| Document | Purpose | Priority |
|---|
| ../_shared/SKILL-DESIGN-SPEC.md | Universal design spec - defines structure, naming, quality standards for all Skills | P0 - Critical |
| specs/reference-docs-spec.md | Reference document generation spec - ensures generated Skills have proper phase-based Reference Documents with usage timing guidance | P0 - Critical |
Template Files (Read Before Generation)
Specification Documents (Read as Needed)
Phase Execution Guides (Reference During Execution)
Execution Flow
Input Parsing:
└─ Convert user request to structured format (skill-name/purpose/mode)
Phase 0: Specification Study (MANDATORY - Must complete before proceeding)
- Read specification documents
- Load: ../_shared/SKILL-DESIGN-SPEC.md
- Load: All templates/*.md files
- Understand: Structure rules, naming conventions, quality standards
- Output: Internalized requirements (in-memory, no file output)
- Validation: MUST complete before Phase 1
Phase 1: Requirements Discovery
- Gather skill requirements via user interaction
- Tool: AskUserQuestion
- Collect: Skill name, purpose, execution mode
- Collect: Phase/Action definition
- Collect: Tool dependencies, output format
- Process: Generate configuration object
- Output: skill-config.json
- Contains: skill_name, execution_mode, phases/actions, allowed_tools
Phase 2: Structure Generation
- Create directory structure and entry file
- Input: skill-config.json (from Phase 1)
- Tool: Bash
- Execute: mkdir -p .claude/skills/{skill-name}/{phases,specs,templates,scripts}
- Tool: Write
- Generate: SKILL.md (entry point with architecture diagram)
- Output: Complete directory structure
Phase 3: Phase/Action Generation
- Decision (execution_mode check):
- IF execution_mode === "sequential": Generate Sequential Phases
- Read template: templates/sequential-phase.md
- Loop: For each phase in config.sequential_config.phases
- Generate: phases/{phase-id}.md
- Link: Previous phase output -> Current phase input
- Write: phases/_orchestrator.md
- Write: workflow.json
- Output: phases/01-{name}.md, phases/02-{name}.md, ...
- ELSE IF execution_mode === "autonomous": Generate Orchestrator + Actions
- Read template: templates/autonomous-orchestrator.md
- Write: phases/state-schema.md
- Write: phases/orchestrator.md
- Write: specs/action-catalog.md
- Loop: For each action in config.autonomous_config.actions
- Read template: templates/autonomous-action.md
- Generate: phases/actions/{action-id}.md
- Output: phases/orchestrator.md, phases/actions/*.md
Phase 4: Specs & Templates
- Generate domain specifications and templates
- Input: skill-config.json (domain context)
- Reference: [specs/reference-docs-spec.md](specs/reference-docs-spec.md) for document organization
- Tool: Write
- Generate: specs/{domain}-requirements.md
- Generate: specs/quality-standards.md
- Generate: templates/agent-base.md (if needed)
- Output: Domain-specific documentation
Phase 5: Validation & Documentation
- Verify completeness and generate usage guide
- Input: All generated files from previous phases
- Tool: Glob + Read
- Check: Required files exist and contain proper structure
- Tool: Write
- Generate: README.md (usage instructions)
- Generate: validation-report.json (completeness check)
- Output: Final documentation
Execution Protocol:
Read('.claude/skills/_shared/SKILL-DESIGN-SPEC.md');
Read('.claude/skills/skill-generator/templates/*.md');
const answers = AskUserQuestion({
questions: [
{ question: "Skill name?", header: "Name", options: [...] },
{ question: "Execution mode?", header: "Mode", options: ["Sequential", "Autonomous"] }
]
});
const config = generateConfig(answers);
const workDir = `.workflow/.scratchpad/skill-gen-${timestamp}`;
Write(`${workDir}/skill-config.json`, JSON.stringify(config));
const skillDir = `.claude/skills/${config.skill_name}`;
Bash(`mkdir -p "${skillDir}/phases" "${skillDir}/specs" "${skillDir}/templates"`);
Write(`${skillDir}/SKILL.md`, generateSkillEntry(config));
if (config.execution_mode === 'sequential') {
Write(`${skillDir}/phases/_orchestrator.md`, generateOrchestrator(config));
Write(`${skillDir}/workflow.json`, generateWorkflowDef(config));
config.sequential_config.phases.forEach(phase => {
Write(`${skillDir}/phases/${phase.id}.md`, generatePhase(phase, config));
});
} else {
Write(`${skillDir}/phases/orchestrator.md`, generateAutonomousOrchestrator(config));
Write(`${skillDir}/phases/state-schema.md`, generateStateSchema(config));
config.autonomous_config.actions.forEach(action => {
Write(`${skillDir}/phases/actions/${action.id}.md`, generateAction(action, config));
});
}
Write(`${skillDir}/specs/${config.skill_name}-requirements.md`, generateRequirements(config));
Write(`${skillDir}/specs/quality-standards.md`, generateQualityStandards(config));
const validation = validateStructure(skillDir);
Write(`${skillDir}/validation-report.json`, JSON.stringify(validation));
Write(`${skillDir}/README.md`, generateReadme(config, validation));
