v3.1.0 — Hub-Skill Architecture & Team Consolidation

Highlights

• Hub-Skill Routing: 26 hub skills route to 167 sub-skills via routing decision trees, replacing flat-list skill matching
• Team Consolidation: /team-assemble reduced from 35 to 21 templates (40% reduction) with alias backward compatibility
• 28 new skills + 3 commands closing knowledge gaps across all 3 suites
• 24 agents optimized: 18 background-enabled for parallel dispatch, 9 promoted to opus tier
• Security hardening: auto-commit gated behind --auto-commit flag, package name validation, hook regex anchoring

By the Numbers

Team Consolidation Details

5 merged teams (from overlapping pairs):

• pr-review ← pr-review + full-pr-review
• quality-security ← quality-audit + security-harden + code-health
• sci-compute ← sci-pipeline + dl-research
• md-simulation ← md-campaign + ml-forcefield
• docs-publish ← docs-sprint + reproducible-research

Old team names work as aliases — no breaking changes.

Quality

• 60/60 tests pass
• 0 lint errors (ruff), 0 type errors (mypy)
• 193/193 skills within 2% context budget
• Zero orphaned skills
