| description | Generate or convert Claude Code prompt files — command orchestrators, skill files, agent role definitions, or style conversion of existing files. Follows GSD-style content separation with built-in quality gates. Triggers on "create command", "new command", "create skill", "new skill", "create agent", "new agent", "convert command", "convert skill", "convert agent", "prompt generator", "优化". |

Agent timeout: spawn_agent 异步执行且无内置超时 — 除明确短任务外一律 spawn_agent 后立即 wait_agent({ timeout_ms: 3600000 })(上限 1 小时)阻塞等待,绝不依赖 30000 默认值;timed_out: true 且 Agent 未完成时再次 wait_agent 续等,不丢弃。批量场景使用 spawn_agents_on_csv({ max_runtime_seconds: 3600, ... })。
Generate or convert Claude Code prompt files with concrete, domain-specific content. Four modes:
- Create command — new orchestration workflow at
.claude/commands/ or ~/.claude/commands/
- Create skill — new skill file at
.claude/skills/*/SKILL.md (progressive loading, no @ refs)
- Create agent — new role + expertise file at
.claude/agents/
- Convert — restyle existing command/skill/agent to GSD conventions with zero content loss
Content separation principle (from GSD): commands/skills own orchestration flow; agents own domain knowledge. Skills are loaded progressively inline; @ references are reserved for mandatory shared lifecycle contracts such as @~/.maestro/workflows/run-mode.md, while phase/domain material remains progressively loaded.
Invoked when user requests "create command", "new command", "create skill", "new skill", "create agent", "new agent", "convert command", "convert skill", "convert agent", "prompt generator", or "优化".

Pre-load (before execution)
- Codebase docs: If
.workflow/codebase/ARCHITECTURE.md exists, read for project context
- Specs:
maestro load --type spec --category coding — load coding conventions
- Wiki knowledge:
maestro search "skill design optimization" --json — top 5 entries as prior context
- All optional — proceed without if unavailable
1. Determine Artifact Type
Parse $ARGUMENTS to determine what to generate.
| Signal | Type |
|---|
| "command", "workflow", "orchestrator" in args | command |
"skill", "SKILL.md" in args, or path contains .claude/skills/ | skill |
| "agent", "role", "worker" in args | agent |
| "convert", "restyle", "refactor", "optimize", "优化" + file path in args | convert |
| Ambiguous or missing | Ask user |
Convert mode detection: If args contain a file path (.md extension) + conversion keywords, enter convert mode. Extract $SOURCE_PATH from args. Auto-detect source type from path:
.claude/commands/ → command
.claude/skills/*/SKILL.md → skill
.claude/agents/ → agent
Skill vs Command distinction: Skills (.claude/skills/*/SKILL.md) are loaded progressively inline. Stateful skills MUST read the canonical Run lifecycle through <required_reading>; phase/domain files continue to use progressive Read() calls. See @specs/command-design-spec.md → "Skill Variant" section.
If ambiguous:
request_user_input(
header: "Artifact Type",
question: "What type of prompt file do you want to generate?",
options: [
{ label: "Command", description: "New orchestration workflow — process steps, user interaction, agent spawning" },
{ label: "Skill", description: "New skill file — progressive loading, no @ refs, inline Read() for external files" },
{ label: "Agent", description: "New role definition — identity, domain expertise, behavioral rules" },
{ label: "Convert", description: "Restyle existing command/agent/skill to GSD conventions (zero content loss)" }
]
)
Store as $ARTIFACT_TYPE (command | skill | agent | convert).
2. Validate Parameters
If $ARTIFACT_TYPE is convert: Skip to Step 2c.
Extract from $ARGUMENTS or ask interactively:
Common parameters (create mode):
| Parameter | Required | Validation | Example |
|---|
$NAME | Yes | /^[a-z][a-z0-9-]*$/ | deploy, gsd-planner |
$DESCRIPTION | Yes | min 10 chars | "Deploy to production with rollback" |
Command-specific parameters:
| Parameter | Required | Validation | Example |
|---|
$LOCATION | Yes | "project" or "user" | project |
$GROUP | No | /^[a-z][a-z0-9-]*$/ | issue, workflow |
$ARGUMENT_HINT | No | any string | "<phase> [--skip-verify]" |
Agent-specific parameters:
| Parameter | Required | Validation | Example |
|---|
$TOOLS | No | comma-separated tool names | Read, Write, Bash, Glob |
$SPAWNED_BY | No | which command spawns this agent | /plan-phase orchestrator |
Normalize: trim + lowercase for $NAME, $LOCATION, $GROUP.
3. Resolve Target Path
Command:
| Location | Base |
|---|
project | .claude/commands |
user | ~/.claude/commands |
If $GROUP:
$TARGET_PATH = {base}/{$GROUP}/{$NAME}.md
Else:
$TARGET_PATH = {base}/{$NAME}.md
Skill:
$TARGET_PATH = .claude/skills/{$NAME}/SKILL.md
Agent:
$TARGET_PATH = .claude/agents/{$NAME}.md
Check if $TARGET_PATH exists → $FILE_EXISTS.
4. Gather Requirements
4a. Pattern discovery — Find 3+ similar files in the project for style reference:
ls .claude/commands/**/*.md 2>/dev/null | head -5
ls .claude/agents/*.md 2>/dev/null | head -5
Read 1-2 similar files to extract patterns: section structure, naming conventions, XML tag usage, prompt style.
4b. Domain inference from $NAME, $DESCRIPTION, and context:
| Signal | Extract |
|---|
$NAME | Action verb → step/section naming |
$DESCRIPTION | Domain keywords → content structure |
$ARGUMENT_HINT | Flags → parse_input logic (command only) |
$SPAWNED_BY | Upstream contract → role boundary (agent only) |
For commands — determine complexity:
| Complexity | Criteria | Steps |
|---|
| Simple | Single action, no flags | 3-5 numbered steps |
| Standard | 1-2 flags, clear workflow | 5-8 numbered steps |
| Complex | Multiple flags, agent spawning | 8-14 numbered steps |
For agents — determine expertise scope:
| Scope | Criteria | Sections |
|---|
| Focused | Single responsibility | <role> + 1-2 domain sections |
| Standard | Multi-aspect domain | <role> + 2-4 domain sections |
| Expert | Deep domain with rules | <role> + 4-6 domain sections |
If unclear, ask user with request_user_input.
5. Generate Content
Route to the appropriate generation logic based on $ARTIFACT_TYPE.
5a. Command Generation
Follow @specs/command-design-spec.md and @templates/command-md.md.
Generate a complete command file with:
<purpose> — 2-3 sentences: what + when + what it produces
<required_reading> — @ references to context files
<process> — numbered steps (GSD workflow style):
- Step 1: Initialize / parse arguments
- Steps 2-N: Domain-specific orchestration logic
- Each step: banner display, validation, agent spawning via
spawn_agent(), error handling
- Final step: status display +
<offer_next> with next actions
<success_criteria> — checkbox list of verifiable conditions
Command writing rules:
- Steps are numbered (
## 1., ## 2.) — follow plan-phase.md and new-project.md style
- Use banners for phase transitions:
━━━ SKILL ► ACTION ━━━
- Agent spawning uses
spawn_agent({ task_name: "<task_name>", message: "<message>" }) pattern
- Prompt to agents uses
<objective>, <files_to_read>, <output> blocks
- Include
<offer_next> block with formatted completion status
- Handle agent return markers:
## TASK COMPLETE, ## TASK BLOCKED, ## CHECKPOINT REACHED
- Shell blocks use heredoc for multi-line, quote all variables
- Include
<auto_mode> section if command supports --auto flag
5a-skill. Skill Generation (variant of command)
Follow @specs/command-design-spec.md → "Skill Variant" section.
Skills are command-like orchestrators loaded progressively inline. The canonical Run workflow is the allowed shared startup dependency; other large context remains progressive.
Generate a complete skill file with:
<purpose> — 2-3 sentences: what + when + what it produces
- Run dependency only — stateful skills include
@~/.maestro/workflows/run-mode.md; other external files are loaded via Read() within process steps.
<process> — numbered steps (GSD workflow style):
- Step 1: Initialize / parse arguments / set workflow preferences
- Steps 2-N: Domain-specific orchestration logic with inline
Read("phases/...") for phase files
- Each step: validation, agent spawning via
spawn_agent(), error handling
- Final step: completion status or handoff to next skill via
Skill()
<success_criteria> — checkbox list of verifiable conditions
Skill-specific writing rules:
- Canonical
<required_reading> only — stateful skills reference @~/.maestro/workflows/run-mode.md; do not eagerly include phase/domain files
- NO
@path references anywhere in the file — use Read("path") within <process> steps
- Phase files loaded on-demand:
Read("phases/01-xxx.md") within the step that needs it
- Frontmatter uses
allowed-tools: (not argument-hint:)
<offer_next> is optional — skills often chain via Skill() calls
<auto_mode> can be inline within <process> step 1 or as standalone section
5b. Agent Generation
Follow @specs/agent-design-spec.md and @templates/agent-md.md.
Generate a complete agent definition with:
- YAML frontmatter — name, description, tools, color (optional)
<role> — identity + spawned-by + core responsibilities + mandatory initial read
- Domain sections (2-6 based on scope):
<philosophy> — guiding principles, anti-patterns
<context_fidelity> — how to honor upstream decisions
<task_breakdown> / <output_format> — concrete output rules with examples
<quality_gate> — self-check criteria before returning
- Custom domain sections as needed
- Output contract — structured return markers to orchestrator
Agent writing rules:
<role> is ALWAYS first after frontmatter — defines identity
- Each section owns ONE concern — no cross-cutting
- Include concrete examples (good vs bad comparison tables) in every domain section
- Include decision/routing tables for conditional logic
- Quality gate uses checkbox format for self-verification
- Agent does NOT contain orchestration logic, user interaction, or argument parsing
5c. Convert Mode (Restyle Existing File)
CRITICAL: Zero content loss. Follow @specs/conversion-spec.md.
Step 5c.1: Read and inventory source file.
Read $SOURCE_PATH completely. Build content inventory:
$INVENTORY = {
frontmatter: { fields extracted },
sections: [ { name, tag, line_range, line_count, has_code_blocks, has_tables } ],
code_blocks: count,
tables: count,
total_lines: count
}
Step 5c.2: Classify source type.
| Signal | Type |
|---|
Path in .claude/skills/*/SKILL.md | skill |
allowed-tools: in frontmatter + path in .claude/skills/ | skill |
Contains <process>, <step>, numbered ## N. steps | command |
Contains <role>, tools: in frontmatter, domain sections | agent |
Flat markdown with ## Implementation, ## Phase N + in skills dir | skill (unstructured) |
Flat markdown with ## Implementation, ## Phase N + in commands dir | command (unstructured) |
| Flat prose with role description, no process steps | agent (unstructured) |
Skill-specific conversion rules:
- Minimal
<required_reading> — only shared lifecycle contracts are eager; phase/domain files remain progressive
- NO
@path references anywhere — replace with Read("path") within <process> steps
- If source has
@specs/... or @phases/... refs, convert to Read("specs/...") / Read("phases/...")
- Follow
@specs/conversion-spec.md → "Skill Conversion Rules" section
Step 5c.3: Build conversion map.
Map every source section to its target location. Follow @specs/conversion-spec.md transformation rules.
MANDATORY: Every line of source content must appear in the conversion map. If a source section has no clear target, keep it as a custom section.
Step 5c.4: Generate converted content.
Apply structural transformations while preserving ALL content verbatim:
- Rewrap into GSD XML tags
- Restructure sections to match target template ordering
- Add missing required sections (empty
<quality_gate>, <output_contract>) with TODO markers
- Preserve all code blocks, tables, examples, shell commands exactly as-is
Step 5c.5: Content loss verification (MANDATORY).
Compare source and output:
| Metric | Source | Output | Pass? |
|---|
| Total lines | $SRC_LINES | $OUT_LINES | output >= source × 0.95 |
| Code blocks | $SRC_BLOCKS | $OUT_BLOCKS | output >= source |
| Tables | $SRC_TABLES | $OUT_TABLES | output >= source |
| Sections | $SRC_SECTIONS | $OUT_SECTIONS | output >= source |
If ANY metric fails → STOP, display diff, ask user before proceeding.
Set $TARGET_PATH = $SOURCE_PATH (in-place conversion) unless user specifies output path.
Content quality rules (both types):
- NO bracket placeholders (
[Describe...]) — all content concrete
- NO generic instructions ("handle errors appropriately") — be specific
- Include domain-specific examples derived from
$DESCRIPTION
- Every shell block: heredoc for multi-line, quoted variables, error exits
6. Quality Gate
MANDATORY before writing. Read back the generated content and validate against type-specific checks.
6a. Structural Validation (both types)
| Check | Pass Condition |
|---|
| YAML frontmatter | Has name + description |
| No placeholders | Zero [...] or {...} bracket placeholders in prose |
| Concrete content | Every section has actionable content, not descriptions of what to write |
| Section count | Command: 3+ sections; Agent: 4+ sections |
6b. Command-Specific Checks
| Check | Pass Condition |
|---|
<purpose> | 2-3 sentences, no placeholders |
<process> with numbered steps | At least 3 ## N. headers |
| Step 1 is initialization | Parses args or loads context |
| Last step is status/report | Displays results or routes to <offer_next> |
| Agent spawning (if complex) | spawn_agent({ call with subagent_type |
| Agent prompt structure | <files_to_read> + <objective> or <output> blocks |
| Return handling | Routes on ## TASK COMPLETE / ## TASK BLOCKED markers |
<offer_next> | Banner + summary + next command suggestion |
<success_criteria> | 4+ checkbox items, all verifiable |
| Content separation | No domain expertise embedded — only orchestration |
6b-skill. Skill-Specific Checks
| Check | Pass Condition |
|---|
<purpose> | 2-3 sentences, no placeholders |
| Canonical Run reference | Stateful skills contain @~/.maestro/workflows/run-mode.md exactly once |
| No eager phase/domain references | Zero @specs/, @phases/, @./ patterns in prose |
<process> with numbered steps | At least 3 ## N. headers |
| Step 1 is initialization | Parses args, sets workflow preferences |
| Phase file loading | Uses Read("phases/...") within process steps (if has phases) |
<success_criteria> | 4+ checkbox items, all verifiable |
Frontmatter allowed-tools | Present and lists required tools |
| Content separation | No domain expertise embedded — only orchestration |
6c. Agent-Specific Checks
| Check | Pass Condition |
|---|
YAML tools field | Lists tools agent needs |
<role> is first section | Appears before any domain section |
<role> has spawned-by | States which command spawns it |
<role> has mandatory read | <files_to_read> instruction present |
<role> has responsibilities | 3+ bullet points with verb phrases |
| Domain sections named | After domain concepts, not generic (<rules>, <guidelines>) |
| Examples present | Each domain section has 1+ comparison table or decision table |
<output_contract> | Defines return markers (COMPLETE/BLOCKED/CHECKPOINT) |
<quality_gate> | 3+ checkbox self-check items |
| Content separation | No request_user_input, no banner display, no argument parsing |
6d. Quality Gate Result
Count errors and warnings:
| Gate | Condition | Action |
|---|
| PASS | 0 errors, 0-2 warnings | Proceed to write |
| REVIEW | 1-2 errors or 3+ warnings | Fix errors, display warnings |
| FAIL | 3+ errors | Re-generate from step 5 |
If FAIL and second attempt also fails:
request_user_input(
header: "Quality Gate Failed",
question: "Generated content failed quality checks twice. How to proceed?",
options: [
{ label: "Show issues and proceed", description: "Write as-is, fix manually" },
{ label: "Provide more context", description: "I'll give additional details" },
{ label: "Abort", description: "Cancel generation" }
]
)
7. Write and Verify
If $FILE_EXISTS: Warn user before overwriting.
mkdir -p "$(dirname "$TARGET_PATH")"
Write content to $TARGET_PATH using Write tool.
Post-write verification — Read back and confirm file integrity:
- File exists and is non-empty
- Content matches what was generated (no corruption)
- File size is reasonable (command: 50-500 lines; agent: 80-600 lines)
If verification fails: Fix in-place with Edit tool.
