v1.8.0 — Leaner, Smarter, Tested

This release was battle-tested with full SDD flows on both Claude Code and OpenCode before going stable. Every phase ran, every artifact persisted, every sub-agent loaded the right skills.

The Numbers

Metric Before (v1.7.x) After (v1.8.0)
SDD prompt tokens per session ~20,650 ~7,700
Lines in SDD skills 1,825 1,421
Orchestrator template variants 2 (97% duplicated) 1 unified
Sub-agent skill discovery Orchestrator-dependent Self-sufficient

63% fewer tokens means more of your context window goes to actual work, not instructions.

What Changed

Token Optimization — All shared patterns (skill loading, engram retrieval, artifact persistence, return envelopes) extracted to sdd-phase-common.md. Phase skills now contain only what's unique to each phase. Net: -340 lines across 11 files.

Self-Sufficient Sub-Agents — Phase sub-agents (sdd-explore, sdd-spec, sdd-apply, etc.) no longer wait for the orchestrator to provide skill paths. They discover the skill registry themselves via engram search or .atl/skill-registry.md fallback, then load project-relevant skills automatically. A sdd-apply on React loads React 19 patterns; on Go it loads Go testing conventions.

Per-Agent Model Routing (OpenCode) — resolveAgentModel() reads each agent's model from config and passes it through session.prompt(). Configure Opus for spec/design, Sonnet for everything else — each phase actually uses its assigned model now.

Upgrade Progress — gentle-ai upgrade shows real-time status instead of a blank screen while brew/binary upgrades run.

Unified Orchestrators — Claude Code and Generic orchestrator templates are now identical and agent-agnostic. One source of truth.

Validated With Real SDD Flows

Claude Code — Feature: add-dashboard-view on a Bun + React 19 + Tailwind 4 project
