Request: Core Skill Inheritance and Missing Skills

Request Summary

Extract shared task workflow into a common base, then let specialized skills add only their unique context.

Scope

• Add shared task-core-loop skill.
• Refactor existing skills to inherit from task-core-loop.
• Add missing user-visible skills:
• task-delivery-sprint-loop
• runtime-parity-audit
• wiki-hygiene-audit

Status

Implemented

Evidence

• Added .github/skills/task-core-loop/SKILL.md.
• Added .github/skills/task-delivery-sprint-loop/SKILL.md.
• Added .github/skills/runtime-parity-audit/SKILL.md.
• Added .github/skills/wiki-hygiene-audit/SKILL.md.
• Updated existing skills to reference inheritance model.

Rename note (2026-05-31): canonical names were later simplified from prompt-runtime-parity-audit and wiki-memory-hygiene-audit to runtime-parity-audit and wiki-hygiene-audit for clearer skill identity.

Follow-Up

• Consider adding a lightweight test/check that every implementation-focused skill references task-core-loop.
