Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/l3wi/claude-eda --skill eda-drc- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads eda-drc automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

EDA DRC Skill
Design validation, rule checking, and pre-manufacturing review.
Auto-Activation Triggers
This skill activates when:
- User asks to "check design", "validate", "run DRC"
- User asks about design errors or warnings
- User mentions manufacturing readiness
- Project is approaching completion
- User asks "is this ready for fabrication?"
Context Requirements
Requires:
hardware/*.kicad_sch- Schematic fileshardware/*.kicad_pcb- PCB layoutdocs/design-constraints.json- Project constraintsdocs/component-selections.md- Selected components
Produces:
docs/validation-report.md- Comprehensive validation report
Validation Scopes
/eda-check schematic
- Run ERC (Electrical Rules Check)
- Verify power connections
- Check decoupling capacitors
- Validate against datasheet requirements
- Check component values
/eda-check pcb
- Run DRC (Design Rules Check)
- Verify placement guidelines
- Check routing rules
- Validate copper pours
- Review silkscreen
/eda-check components
- Verify stock availability on LCSC
- Check current pricing
- Identify lifecycle issues
- Suggest alternatives if needed
/eda-check manufacturing
- Generate and review Gerbers
- Verify BOM completeness
- Check position file accuracy
- Validate against manufacturer specs
/eda-check full
- Run all above checks
- Comprehensive pre-manufacturing validation
Workflow
1. Load Context
@docs/design-constraints.json
@docs/component-selections.md
@docs/schematic-status.md
@docs/pcb-status.md
2. Run Automated Checks
- Execute DRC/ERC via KiCad MCP
- Capture all violations and warnings
3. Manual Review Checklist
Use reference documents to verify:
- Common issues are addressed
- Manufacturer constraints are met
- Design guidelines followed
4. Component Verification
For each selected component:
- Check LCSC stock status
- Verify pricing
- Check for lifecycle warnings
5. Generate Report
Create comprehensive validation report documenting:
- Pass/fail status for each check
- List of issues found
- Recommended actions
- Sign-off status
