Patch Release

v6.1.1

2026-05-07

🐛Fixed

  • Stale "Manual merge recommended" advisory no longer appears when migrate-v5-to-v6.sh runs as a subprocess of install.sh --upgrade
  • Standalone migrate-v5-to-v6.sh now points users at install.sh --upgrade as the recommended automatic path
Minor Release

v6.1.0

2026-05-07

✨Added

  • install.sh --upgrade flag — single-command v5 to v6 migration with full rollback
  • install.sh --dry-run — preview the migration plan without making changes
  • install.sh --non-interactive — bulk-mode contract for CI and multi-repo scripts
  • Settings.json surgical merge — your values win on conflict; user customisations preserved through upgrade
  • restore-pre-upgrade.sh — first-class rollback with --list, --latest, --backup, --settings modes
  • docs/UPGRADE.md — focused upgrade guide for v5.x users
  • Five end-to-end test fixtures (43/43 checks) covering clean v5, custom settings, malformed JSON, partial migration, and already-v6 cases

🔄Changed

  • migrate-v5-to-v6.sh distinguishes three previously-ambiguous cases (already-v6, completed-previously, in-progress) with itemised actions
  • Post-install summary no longer claims tool deferring is enabled when settings.json was not actually merged
Major Release

v6.0.0

2026-05-03

✨Added

  • Karpathy operating constitution — seven behavioural principles (PAUSE-AND-PLAN, state assumptions, prefer minimal diffs, verify by running) replace prompt-based "always do X" rules
  • Universal Router (/coord [mission]) — deterministic mission-based routing across 13 missions in three modes (greenfield, surgical, maintenance). No more NLP intent inference
  • Native MCP tool deferring via ENABLE_TOOL_SEARCH=auto — roughly 80% context reduction on MCP-heavy sessions
  • Quality-gate hooks in .claude/settings.json — advisory PostToolUse for tsc/ruff/rubocop, PreToolUse confirmation for destructive Bash
  • Phase Handoff blocks — structured 5-field schema (Findings / Decisions / Warnings / Open Items / Evidence) appended to agent-context.md
  • 3-tier skills model aligned with Anthropic's Agent Skills open standard
  • Routines for Mode C operational work (PR review, nightly QA, backlog triage)
  • migrate-v5-to-v6.sh — one-command migration script for v5.x users

🔄Changed

  • library/CLAUDE.md shrunk from 575 lines to 78 lines (-86%)
  • project/commands/coord.md shrunk from 549 lines to 134 lines
  • Active context tracking reduced from 5 files to 3
  • progress.md demoted to write-only by default (read only on staleness checks)

🗑️Removed

  • MCP profile system (.mcp-profiles/, /mcp-switch command) — replaced by native tool deferring
  • Static handoff-notes.md workflow — folded into agent-context.md as Phase Handoff blocks
  • NLP-based mission intent inference in /coord — replaced by deterministic dispatch
Major Release

v5.0.0

2025-12-31

✨Added

  • Plan-Driven Development System — /foundations init, /bootstrap [template], /plan status, /coord continue, /skills
  • 7 production-ready SaaS skills with auto-loading by task keywords (auth, payments, multitenancy, billing, email, onboarding, analytics)
  • Quality Gates System — Python gate runner with build/test/lint/security/review/deploy gates and 3 severity levels
  • Stack Profiles for multi-framework support (nextjs-supabase, remix-railway, sveltekit-supabase)
  • Smart Delegation Routing — 10-path routing table with skill injection
  • Vision Integrity Verification (ALIGNED, MINOR_DRIFT, MAJOR_DRIFT, OUT_OF_SCOPE)
Major Release

v4.1.0

2025-11-28

✨Added

  • MCP Context Optimization with 60-90% token reduction
  • 13 mission-specific MCP profiles (minimal-core, research-only, frontend-deploy, etc.)

🔄Changed
