Setup lidessen skills

Operational deployer for the lidessen skills collection. The lidessen methodology lives in the individual skills (harness, design-driven, goal-driven, reframe, evidence-driven, etc.); this skill does the wiring to land them in a target project — detect the host tool, write to the right harness file, and inject the cross-cutting principles that span multiple lidessen skills.

Position relative to harness

harness (and any general-purpose harness skill) teaches how to think about agent context — portable methodology, applies to any project regardless of skill collection. This skill is the lidessen-specific operational layer that applies harness-style structure to a project adopting the lidessen collection. Read harness for the why; run this skill to do the wiring.

Boundary — what this skill does and doesn't

Does:

• Detect host tool (Claude Code / Codex / Cursor / other) by config-file presence
• Create or update the project's harness config with a delimited "Lidessen" section
• Inject canonical cross-cutting principles from references/cross-cutting-principles.md
• Maintain a version marker so subsequent sync / audit runs can detect drift
