name	woodworking-plan-generator
description	Generate practical woodworking project designs using standard lumber, actual dimensions, parametric sizing, and build-ready assemblies. Use when a user asks for woodworking plans, furniture/project design, dimensional build specs, or a buildable concept before rendering, cut-list generation, or SketchUp modeling.

Role

Turn a user request into a buildable woodworking design spec before any rendering or cut-list work starts.

References

Read these when helpful:

• references/lumber.md for actual lumber dimensions and stock defaults
• references/design-rules.md for design priorities, joinery defaults, and clarification triggers
• references/project-types.md for project-specific heuristics

Core rules

• Use actual dimensions, not nominal lumber sizes.
• Prefer the fewest lumber types practical.
• Allow ripped stock when useful.
• Break the project into load-bearing structure, secondary structure, trim/slats, and hardware.
• Design for buildability, not just appearance.
• Prefer simple joinery and repeatable parts unless the user asks for a more advanced build.
• State assumptions explicitly so later skills preserve them.

Stop-and-ask conditions

If any of these are missing or ambiguous, do not finalize the design without calling them out:

• overall target dimensions
• load or use assumptions
• indoor vs outdoor use
• hanging / mounting conditions
• material restrictions
• safety-critical context such as child use, elevated loads, or suspension

If needed, proceed with a provisional design, but label assumptions clearly.

Required process

1. Identify project type and use case.
2. Establish overall dimensions and fit clearances.
3. Identify missing constraints and safety-sensitive assumptions.
4. Select material strategy.
5. Define major assemblies.
6. Define joinery defaults.
7. Note assumptions that later skills must preserve.

Output

Produce these sections:

• Design Summary
• Overall / Parametric Dimensions
• Material Strategy
• Assembly Breakdown
• Joinery Defaults
• Assumptions
• Open Questions (if anything important is still missing)

Hand-off

Pass the design to:

• structural-validator-skill for safety review
• sketchup-mcp-bridge for modeling
• plan-renderer-skill for plan sheets
• cut-list-skill for lumber optimization
