+# Create Capability
+
+@~/.claude/skills/capability-writing/SKILL.md
+
+Create new capabilities following latest Anthropic best practices (progressive disclosure, script bundling, Haiku-first).
+
+## Process
+
+1. **Understand the capability**: Analyze "$1" to understand what the user wants to build
+   - What domain or workflow does this cover?
+   - What user need does it address?
+   - What existing capabilities might overlap?
+
+2. **Determine components needed**: Based on the description, recommend which components:
+
+   | Pattern | When to Use |
+   |---------|-------------|
+   | Skill only (background) | Knowledge to apply automatically (reused across other skills) |
+   | Skill only (user-invocable) | User-invoked workflow |
+   | Skill + Agent | Workflow with isolated worker for complex subtasks |
+   | Full set | New domain expertise + workflow + isolated work |
+
+   Present recommendation with reasoning:
+   ```
+   ## Recommended Components for: $1
+
+   Based on your description, I recommend:
+   - **Skill**: `name` - [why this knowledge is needed]
+   - **Agent**: `name` - [why isolation/specialization is needed] (optional)
+
+   Reasoning: [explain why this combination fits the need]
+   ```
+
+3. **Analyze complexity** (NEW): For each skill, determine structure needed:
+
+   **Ask these questions:**
+
+   a) **Expected size**: Will this skill be >300 lines?
+      - If NO → Simple structure (just SKILL.md)
+      - If YES → Suggest progressive disclosure
+
+   b) **Error-prone operations**: Are there complex bash operations?
+      - Check for: PR creation, worktree management, complex git operations
+      - If YES → Suggest bundling scripts
+
+   c) **Degree of freedom**: What instruction style is appropriate?
+      - Multiple valid approaches → Text instructions (high freedom)
+      - Preferred pattern with variation → Templates (medium freedom)
+      - Fragile operations, exact sequence → Scripts (low freedom)
+
+   **Present structure recommendation:**
+   ```
+   ## Recommended Structure
+
+   Based on complexity analysis:
+   - **Size**: [Simple | Progressive disclosure]
+   - **Scripts**: [None | Bundle error-prone operations]
+   - **Degrees of freedom**: [High | Medium | Low]
+
+   Structure:
+   [Show folder structure diagram]
+   ```
+
+4. **Gather information**: For each recommended component, ask:
+
+   **For all components:**
+   - Name (kebab-case, descriptive)
+   - Description (one-line summary including trigger conditions)
+
+   **For Skills:**
+   - What domain/knowledge does this cover?
+   - What are the key concepts to teach?
+   - What patterns or templates should it include?
+   - Is it user-invocable (workflow) or background (reference)?
+
+   **For Agents:**
+   - What specialized role does this fill?
+   - What skills does it need?
+   - Should it be read-only (no Edit/Write)?
+
+5. **Select appropriate models** (UPDATED):
+
+   **Default to Haiku, upgrade only if needed:**
+
+   | Model | Use For | Cost vs Haiku |
+   |-------|---------|---------------|
+   | `claude-haiku-4-5` | Most skills and agents (DEFAULT) | Baseline |
+   | `claude-sonnet-4-5` | When Haiku would struggle (<80% success rate) | 12x more expensive |
+   | `claude-opus-4-5` | Deep reasoning, architectural analysis | 60x more expensive |
+
+   **Ask for justification if not Haiku:**
+   - "This looks like a simple workflow. Should we try Haiku first?"
+   - "Does this require complex reasoning that Haiku can't handle?"
+
+   For each component, recommend Haiku unless there's clear reasoning for Sonnet/Opus.
+
+6. **Generate files**: Create content using templates from capability-writing skill
+
+   **Structure options:**
+
+   a) **Simple skill** (most common):
+   ```
+   skills/skill-name/
+   └── SKILL.md
+   ```
+
+   b) **Progressive disclosure** (for large skills):
+   ```
+   skills/skill-name/
+   ├── SKILL.md (~200-300 lines)
+   ├── reference/
+   │   ├── detailed-guide.md
+   │   └── api-reference.md
+   └── examples/
+       └── usage-examples.md
+   ```
+
+   c) **With bundled scripts** (for error-prone operations):
+   ```
+   skills/skill-name/
+   ├── SKILL.md
+   ├── reference/
+   │   └── error-handling.md
+   └── scripts/
+       ├── validate.sh
+       └── process.sh
+   ```
+
+   **Ensure proper inter-references:**
+   - User-invocable skill references background skills via `@~/.claude/skills/name/SKILL.md`
+   - Agent lists skills in `skills:` frontmatter (names only, not paths)
+   - User-invocable skill spawns agent via Task tool if agent is part of the set
+   - Scripts are called with `./scripts/script-name.sh` in SKILL.md
+
+7. **Present for approval**: Show all generated files with their full content:
+   ```
+   ## Generated Files
+
+   ### skills/name/SKILL.md
+   [full content]
+
+   ### skills/name/scripts/helper.sh (if applicable)
+   [full content]
+
+   ### agents/name/AGENT.md (if applicable)
+   [full content]
+
+   Ready to create these files?
+   ```
+
+8. **Create files** in correct locations after approval:
+   - Create directories if needed
+   - `skills/<name>/SKILL.md`
+   - `skills/<name>/scripts/` (if scripts recommended)
+   - `skills/<name>/reference/` (if progressive disclosure)
+   - `agents/<name>/AGENT.md` (if agent recommended)
+
+9. **Report success**:
+   ```
+   ## Capability Created: name
+
+   Files created:
+   - skills/name/SKILL.md
+   - skills/name/scripts/helper.sh (if applicable)
+   - agents/name/AGENT.md (if applicable)
+
+## Guidelines (UPDATED)
+
+- Follow all conventions from capability-writing skill
+- **Default to Haiku** for all new skills/agents (12x cheaper, 2-5x faster)
+- **Bundle scripts** for error-prone bash operations
+- **Use progressive disclosure** for skills >500 lines
+- Reference existing skills rather than duplicating knowledge
+- Keep components focused - split if scope is too broad
+- User-invocable skills should have approval checkpoints
+- Skills should have descriptive `description` fields with trigger conditions
+- **Be concise** - assume Claude knows basics
+
+## Output Style
+
+Be concise and direct:
+- No preambles ("I'll help you...")
+- No sign-offs ("Let me know...")
+- Show structure diagrams clearly
+- Use tables for comparisons
+- One decision per section
