v5.0.9

Changed

• design SKILL.md optimized: Single-vs-batch spec handling moved to a dedicated section, eliminating repetition across workflow steps. Workflow condensed. T1–T3 refactoring framework consolidated into a reference table. Scale awareness and design self-challenge retained as key behavioral content.
• spec SKILL.md optimized: Behavioral quality checklist merged into the pre-delivery verification step. Workflow tightened with less repetition. Removed broken internal references.
• discuss SKILL.md optimized: Clarified requirement summaries, which replace functional module design. PROPOSAL.md template section 5 updated from "Functional Module Design" to "Requirement Summary" with a simpler bullet format.
• fix SKILL.md simplified: Condensed from a verbose multi-section coordinator prompt to an essential 4-step workflow. Removed boilerplate that duplicated PROMPT.md content.
• implement SKILL.md simplified: Same treatment as fix — condensed to an essential 4-step coordinator workflow.

Removed

• fix auxiliary files: skills/fix/CHANGELOG.md, skills/fix/README.md, and skills/fix/assets/templates/fix-summary.md removed as outdated.
• implement references: skills/implement/references/branch-naming.md removed.
• spec references: skills/spec/references/spec-quality-checklist.md removed — behavioral content merged into SKILL.md pre-delivery verification.
