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

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:

// Phase 0: Read specifications (in-memory)
Read('.claude/skills/_shared/SKILL-DESIGN-SPEC.md');
Read('.claude/skills/skill-generator/templates/*.md'); // All templates

// Phase 1: Gather requirements
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));

// Phase 2: Create structure
const skillDir = `.claude/skills/${config.skill_name}`;
Bash(`mkdir -p "${skillDir}/phases" "${skillDir}/specs" "${skillDir}/templates"`);
Write(`${skillDir}/SKILL.md`, generateSkillEntry(config));

// Phase 3: Generate phases (mode-dependent)
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));
  });
}

// Phase 4: Generate specs
Write(`${skillDir}/specs/${config.skill_name}-requirements.md`, generateRequirements(config));
Write(`${skillDir}/specs/quality-standards.md`, generateQualityStandards(config));


// Phase 5: Validate & Document
const validation = validateStructure(skillDir);
Write(`${skillDir}/validation-report.json`, JSON.stringify(validation));
Write(`${skillDir}/README.md`, generateReadme(config, validation));
