Changelog

🚧 A full changelog is still being assembled. The list below is a feature snapshot of the current Luker release.

Current version

Orchestrator

• Custom tools — extend agents in any of the four orchestration modes with handwritten tools, tools from other Luker extensions, or bridged SillyTavern function tools.
• Handwritten custom tools travel with the profile; profile-scoped tools attached to a character override are exported with the card.
• Iteration Studio sees the visible custom tools and can toggle them on or off per profile.

Core features

• Memory Graph — Knowledge-graph long-term memory, 9-layer hybrid recall pipeline
• Multi-Agent Orchestrator — Three execution modes (Spec workflow, Single agent, Agenda planner)
• Card Editor Assistant — AI-driven conversational character-card editing with 7 tools
• Search Tools — Three-engine support: DuckDuckGo, SearXNG, Brave Search
• Preset Assistant — AI-assisted preset editing with IDE-style drift handling and per-message rollback; new fine-grained tools (str_replace / str_insert / list_insert / list_move) save tokens on long fields
• Edits library (public/scripts/lib/edits/) — shared op-typed structured-edit primitives with drift-aware apply + interactive conflict UI, exposed to third-party extensions (ESM / lukerContext / ctx). See docs/development/extension-api/edits-lib.md.
• CardApp — Interactive applications embedded in character cards

Architecture improvements

• Preset Decoupling — Connection parameters and presets managed independently
• Incremental Sync — RFC 6902 incremental data transfer
• Backend Storage — Data changes persisted in real time
• Function Call Runtime — Native + plain-text dual modes
• Unified Generation Layer — Single envelope for multiple backends
• Request Inspector — Full-lifecycle generation-request tracing
• Auth & Quotas — GitHub / Discord OAuth + storage quota management

User experience

• Card-bound presets and personas
• Prompt groups & preset groups
• Hook execution order
• World Info activation trace
• Chat-persona lock
• Undo-toast system
• Dynamic model lists
• Image generation enhancements
• Mobile UX refinements
• Startup performance optimization

Recent breaking changes

• CardApp Studio reverted to its standalone fullscreen UI (the iteration-studio shell version shipped in May 2026 was a brief detour that lost viewport ownership and noticeably degraded UX). The studio now takes over the viewport again via two position:fixed panels with mobile tab support, file tree, CodeMirror 6 editor, and inline approval cards — the pre-SP-2 UX users were used to. File operations still benefit from edits-lib's drift detection + per-op inverse — new capabilities the original standalone version didn't have. The brief-era session bucket (cardapp_studio_sessions_v2) is wiped on first open; CardApp files on disk are untouched.

• edits-lib now supports two integration patterns: wrapping it in the iteration-studio shell for popup-friendly surfaces, or using the library primitives directly for fullscreen / custom-UI. CardApp Studio is the in-tree reference for direct usage.

• CPA rebuilt on the iteration-studio shell (SP-4 of the adapter migration, closes Plan 2). The 309-line dialog-ui.js is deleted; CPA's existing IDE-style business helpers (handleApplyDraft, handleRollbackToMessage, handleMessageDiff) are unchanged and now run inside the shared shell. With SP-4 landed, all five AI-driven editing surfaces in Luker (orchestrator, memory-graph, CEA CardApp Studio, CEA Character Editor, CPA) share one shell, one storage model, one edits-lib, and one conflict-resolution UI.

• CEA CardApp Studio rebuilt on the iteration-studio shell (SP-2 of the adapter migration). The standalone session / popup / diff infrastructure has been replaced with the SP-1 v2 adapter contract: live() is the single authority, the 4 file-write tools route through normalizeToolCallToEdit, the 2 file-read tools through executeControlToolCall, and commit() diffs against the previous snapshot before fanning out to the existing saveFileContent / deleteFile helpers. The old cardapp_studio_sessions character-sidecar bucket is wiped once on first open after upgrade; CardApp files on disk are untouched.

• CEA Character Editor rebuilt on the iteration-studio shell (SP-3 of the adapter migration). The lorebook-sync analysis popup is replaced with a multi-turn iteration session. Edits a character card and its lorebook in one adapter; introduces 3 CEA-owned custom edits-lib ops (lorebook_entry_add / update / remove) keyed by entry uid. The shell now invokes adapter.registerCustomOps(registry) once per open. Old lorebookSyncHistory settings entry is wiped on first open; character cards + lorebooks on disk are untouched.

• Iteration Studio adapter contract v2 (IDE-style). The shell no longer carries a workingProfile snapshot; the adapter's live() is the single authority. In-tree orchestrator + memory-graph adapters migrated. Out-of-tree adapters require updates (see docs/development/extension-api/iteration-studio.md). Old iteration-studio session data is wiped once per adapter on first open after upgrade; live artifacts (preset files, character cards, settings) are untouched. CEA and CPA adapters arrive in subsequent releases.

• CPA conversation rollback resets on upgrade. The journal-based session model was replaced with IDE-style live=authority + per-message appliedEdits. Preset files themselves are unchanged; only CPA's conversation rollback history from prior sessions is lost. New conversations rollback normally via the new mechanism.
