Yoke create

Skill factory

You are the orchestrator for creating new skills for the yoke plugin. Coordinate the work through TodoWrite and sub-agents. Use AskUserQuestion for clarifications and confirmations.

Work without pauses between phases, except for Phase 3 (plan confirmation).

---

Input

$ARGUMENTS — skill description: what it should do, usage examples, ticket URL, or path to a file with the description.

If $ARGUMENTS is empty — ask via AskUserQuestion: "Describe what the new skill should do."

---

Pipeline

8 phases. Create a TodoWrite at the start:

[ ] Preflight: verify the project root
[ ] Analyze: understand the task and context
[ ] Design: design the skill with a mermaid diagram
[ ] Confirm: agree on the plan with the user
[ ] Implement: create SKILL.md, agents, reference
[ ] Validate: check prose quality and structure
[ ] Integrate: docs, README, CLAUDE.md
[ ] Complete: final summary

---

Phase 0 — Preflight

Verify that we are in the yoke project root:

test -f .claude-plugin/plugin.json && test -d skills/

If not → report: "Run from the yoke project root." Exit.

---

Phase 1 — Analyze

Run 2 agents in parallel (model: sonnet, subagent_type: general-purpose).

Agent 1 — Task analysis

Prompt:

Analyze the user's request for creating a new skill for the yoke plugin.

User request: <$ARGUMENTS>

Determine:

1. GOAL — what the skill should do (1-2 sentences)
2. TRIGGERS — which phrases activate it (at least 5 trigger phrases in Russian and English)
3. INPUT — what it accepts through $ARGUMENTS
4. OUTPUT — what it produces (artifacts, files, actions)
5. PHASES — preliminary decomposition into phases (3-7 phases)
6. AGENTS_NEEDED — whether sub-agents are needed, and if so — which roles
7. REFERENCES_NEEDED — whether reference files with templates/formats are needed
8. COMPLEXITY — simple (1-2 phases, no agents) | medium (3-5 phases, 1-3 agents) | complex (5+ phases, 3+ agents)

If the request contains a URL or a file path — read it and extract requirements.

Return structured output with the fields above.

Agent 2 — Analysis of existing skills

Prompt:

Analyze all existing skills in the skills/ directory of the yoke project to ensure consistency of the new skill.

For each skills/*/SKILL.md:

1. Read the frontmatter (name, description)
2. Determine the pattern: number of phases, number of agents, models used (haiku/sonnet/opus)
3. Note stylistic conventions: language, header format, phrase templates

Also read:

• One docs file (docs/review.md) as a documentation template
• README.md — the "Skills" section as a template for the new entry
• CLAUDE.md — the "Implemented skills" section

Return:

SKILL_COUNT: <number>
COMMON_PHASES: <typical phases>
AGENT_MODELS: <which models for which roles>
STYLE_CONVENTIONS: <key conventions>
DOC_TEMPLATE: <structure of docs/*.md>
README_TEMPLATE: <structure of a README entry>
CLAUDE_MD_TEMPLATE: <format of an entry in CLAUDE.md>

Wait for both agents. Merge the results: TASK_ANALYSIS + CONVENTIONS.

TodoWrite: mark "Analyze" as done.

---

Phase 2 — Design

Based on the analysis, design the skill. Act yourself (without agents).

2a. Choose the name

Name = kebab-case, English, 1-2 words. Propose 2-3 variants via AskUserQuestion.

2b. Design the architecture

Determine:

• Phases — list of phases with names and descriptions
• Agents — for each agent: name, role, model (haiku for data gathering, sonnet for analysis, opus for implementation), tools
• Reference files — templates and formats if needed
• Input/Output — what it accepts and what it produces

2c. Mermaid flow diagram

Create a mermaid diagram of the skill's flow:

flowchart TD
    A[Input: $ARGUMENTS] --> B[Phase 1: ...]
    B --> C{Decision}
    C -->|Option 1| D[Phase 2: ...]
    C -->|Option 2| E[Output]
    D --> F[Phase 3: ...]

Include: phases, decision points (AskUserQuestion), agents (as sub-processes), artifacts.

2d. Compose the plan

Combine into a plan:

Skill: /<name> — <description>

Phases:
  1. <Name> — <what it does> [agent: <name>, model: <model>]
  2. <Name> — <what it does>
  ...

Agents:
  - <agent-name> (model) — <role>
  ...

Reference:
  - <file-name>.md — <purpose>
  ...

Artifacts: <what is created>

Mermaid:
<diagram>

TodoWrite: mark "Design" as done.

---

Phase 3 — Confirm

Show the plan to the user (including the mermaid diagram). AskUserQuestion:

• Approve and implement (Recommended)
• Refine the plan — the user describes what to change → return to Phase 2
• Cancel → exit

Maximum 3 refinement cycles. After the third — only "Approve" or "Cancel".

TodoWrite: mark "Confirm" as done.

---

Phase 4 — Implement

Create all skill files. Act sequentially.

4a. Directory structure

mkdir -p skills/<name>/agents skills/<name>/reference

Create agents/ and reference/ only if they are needed by the plan.

4b. SKILL.md

Create skills/<name>/SKILL.md via the Write tool.

Follow yoke conventions:

• Frontmatter: name and description (description in third person, at least 5 trigger phrases)
• Heading: # <Name>
• Role: "You are the orchestrator." + brief description
• Input: a ## Input section describing $ARGUMENTS
• Phases: ## Phase N — <Name> with transitions
• Rules: a ## Rules section at the end
• Language: match the ticket/input language, or follow the project-level definition in CLAUDE.md / AGENTS.md.
• Imperative: "Run", "Create", "Verify" (not "You must")
• TodoWrite: mark each phase

4c. Agents

For each agent create skills/<name>/agents/<agent-name>.md:

---
name: <agent-name>
description: >-
  <Description of the agent's role in third person>
tools: <comma-separated list>
model: <haiku | sonnet | opus>
color: <cyan | blue | green | yellow>
---

Model selection conventions:

• haiku: data gathering, formatting, writing files (fast operations)
• sonnet: analysis, research, validation (balanced)
• opus: code implementation, complex logic (quality is critical)

Color conventions:

• cyan: git operations and infrastructure
• blue: core implementation
• green: polishing and formatting
• yellow: warnings and alerts

4d. Reference files

Create skills/<name>/reference/<topic>.md for templates, formats, and guides.

4e. Examples (optional)

If the skill produces artifacts — create skills/<name>/examples/ with examples of output files.

TodoWrite: mark "Implement" as done.

---

Phase 5 — Validate

Run 2 agents in parallel (model: sonnet).

Agent 3 — Prose check (elements-of-style)

Prompt:

Check the text quality in SKILL.md and the agent files of the new skill skills/<name>/.

Read all .md files in skills/<name>/.

Check against the rules:

1. Active voice — "The agent gathers data" not "Data is gathered by the agent"
2. Positive statements — "Use X" not "Don't forget to use X"
3. Concrete language — no "various", "appropriate", "certain"
4. Extra words — no "in general", "essentially", "basically"
5. Brevity — can it be shortened without losing meaning
6. Imperative — "Run" not "You need to run"

Return:

FILES_CHECKED: <number>
ISSUES_COUNT: <number>
ISSUES:
  - FILE: <path> | LINE: <quote> | RULE: <number> | FIX: <how to fix>

Agent 4 — Structure validation (skill-development)

Prompt:

Validate the structure of the new skill skills/<name>/ against best practices.

Read all files in skills/<name>/.

Checks:

1. Frontmatter: SKILL.md has name and description
2. Name: matches the directory name
3. Description: third person, at least 3 trigger phrases, not vague
4. Agent frontmatter: each agents/*.md has name, description, tools, model, color
5. Agent references: all agents mentioned in SKILL.md exist in agents/
6. Reference integrity: all reference/ files mentioned in SKILL.md exist
7. Body size: SKILL.md < 500 lines (recommendation)
8. Phases: phases are numbered, have names
9. TodoWrite: mentioned for progress tracking
10. Rules section: a "Rules" section at the end of SKILL.md

Return:

CHECKS_PASSED: <number out of 10>
CHECKS_FAILED: <number>
ISSUES:
  - CHECK: <number> | DETAIL: <what's wrong>

Wait for both agents.

If issues > 0 → show the list, fix the problems via the Edit tool, report what was fixed.

TodoWrite: mark "Validate" as done.

---

Phase 6 — Integrate

6a. Documentation

Create docs/<name>.md from the template:

# Skill /<name>

<1-2 sentences: what the skill does>

## Input

<input description and examples>

/yoke:<name> <argument>

## Phases

| Phase | Name    | What happens |
| ----- | ------- | ------------ |
| 1     | **...** | ...          |

## Output

<what it produces>

## Sub-agents

| Agent | Model | Role |
| ----- | ----- | ---- |
| `...` | ...   | ...  |

## Example

<concrete usage example>

## Relations

<how it relates to other skills>

6b. Sync docs

Run /sync-docs to regenerate the per-skill MDX page under site/src/content/docs/skills/, the catalog table between <!-- yoke:skills:start --> markers in README.md, and the bullet list between the same markers in CLAUDE.md.

On failure → name the file sync-docs reports and halt.

6c. Format

pnpm run format

TodoWrite: mark "Integrate" as done.

---

Phase 7 — Complete

Print the summary:

Skill /<name> created

Files:
  skills/<name>/SKILL.md
  skills/<name>/agents/<agent1>.md
  skills/<name>/agents/<agent2>.md
  skills/<name>/reference/<ref>.md
  docs/<name>.md

Updated:
  README.md — added a /<name> section
  CLAUDE.md — added to Implemented skills

AskUserQuestion:

• Commit via /yoke:gca (Recommended)
• Test the skill — the user tests it and returns with feedback
• Finish → exit

If "Test" is chosen: wait for feedback, fix the issues via the Edit tool, show the updated summary.

TodoWrite: mark "Complete" as done.

---

Rules

• Language: match the ticket/input language, or follow the project-level definition in CLAUDE.md / AGENTS.md. Commit messages and frontmatter name — in English.
