v0.13.0

What's New

Tech Lead gets a three-tier orchestration model, a two-phase consultation protocol, and a unified routing system. Three new skills (/plan-implementation, /refine-story cohesion check, /audit-agent-memory) plus drift detection on onboarding.

Tech Lead Orchestration

• Three-tier engagement model with signals catalog for choosing when to consult specialists, plan implementations, or ship directly.
• /plan-implementation skill — two-phase consultation protocol that produces implementation plans with explicit specialist routing.
• Unified specialist routing — the Tech Lead's routing table now derives from agent descriptions, eliminating the duplication between the routing table and individual agent definitions.
• Routing target types — routing targets can now be agents, skills, or external commands, not only agents.
• Routing outcome capture — specialist consultations now record outcomes so the routing table learns which routes delivered value.
• Convention domain ownership — each convention gets a named domain owner responsible for drift checks and evolution.

Refinement

• Refinement cell skill — operationalizes the refinement loop between Product Owner, Agile Coach, and specialists for multi-pass story shaping.
• Story cohesion check added to /refine-story — scores whether acceptance criteria, scope, and outcomes hang together as a single unit of work.

Onboarding

• Agent model override — /onboard now supports per-agent model bias (e.g., assign Opus to the Chief Architect, Haiku to the Engineering Manager).
• Reonboarding drift detection — detects when project context has drifted from what onboarding captured and prompts a refresh.

Memory Hygiene

• /audit-agent-memory skill — advisory audit over agent memory directories, flagging stale, contradictory, or low-value entries.

Upgrade Notes

This release skips v0.12.x. Changes are additive. No breaking changes to existing agent contracts. Re-run /onboard to pick up the new model-override and drift-detection behavior.
