Prune stale .claude/skills/: rpi-design survived its absorption into /rad-research + /rad-design

[seanrreid]

Problem

b0d5d0a absorbed rpi-design into RAD as /rad-research + /rad-design, but .claude/skills/rpi-design/ is still present on main and develop:

.claude/skills/rpi-design/SKILL.md
.claude/skills/rpi-design/phases/01-research.md
.claude/skills/rpi-design/phases/02-plan.md
.claude/skills/rpi-design/phases/03-implement.md
.claude/skills/rpi-design/templates/compaction-template.md
.claude/skills/rpi-design/templates/diagram-template.md
.claude/skills/rpi-design/templates/readme-template.md

A live skill whose description matches "design an agent architecture / scaffold a multi-agent workflow" competes with /rad-design for invocation, and its 03-implement.md phase describes an execution path that does not go through RAD's Gate 2. That is a correctness risk, not just clutter: a skill that can be auto-invoked and that describes implementing without an approved plan is exactly what the deliver gate exists to prevent.

.claude/skills/kickoff/ and .claude/skills/wrap/ should be audited in the same pass — confirm they are still live and still consistent with the current command set, or remove them.

Evidence / framing

HumanLayer's Skill Issue: Harness Engineering for Coding Agents names this failure mode directly: installing skills and servers speculatively and never paring them back, so every session pays context for capability nobody uses. Their "what did work" list is the inverse — carefully paring down exposed capabilities once needs are identified.

RAD is shipping this failure mode in its own tree, and every install inherits it.

Scope

• Remove .claude/skills/rpi-design/ (salvage anything from templates/ that /rad-design should own before deleting).
• Audit kickoff and wrap; keep, fix, or remove.
• Check install.sh and INSTALL.md do not reference the removed paths.
• Check docs for stale rpi-design references.
