From fb7eb3105e1fbbdefdad9348f9132815b5bbe52d Mon Sep 17 00:00:00 2001 From: Adam Malczewski Date: Thu, 20 Aug 2026 19:36:12 +0900 Subject: feat(named-agents): sidebar view, synthetic provider, auto-save, snapshot semantics MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement the frontend of the Named Agents feature (plan §5-§9): - New features/named-agents module: pure logic (types re-exported from @dispatch/wire + transport-contract, validation, provider/model options, snapshot helpers, network normalizers, auto-save status model) + an injected auto-save controller (name debounce, immediate provider/model save, monotonic stale-response guard) + the collapsible sidebar card view. - Store: /named-agents CRUD + boot seed; selectModel(model, snapshot?) persists the raw model WITH the namedAgent snapshot; draft promotion carries it; refreshModel restores ModelResponse.namedAgent. - Chat store setNamedAgent (sends namedAgent on chat.send); Tab.snapshot + setSnapshot (retained across rename/remove, persisted with tabs). - Model selector: synthetic Named Agents provider ALWAYS first; selecting one resolves to the raw model + records a snapshot; a retained snapshot of a renamed/removed agent still displays as unavailable (plan §7). - Composition root wires the view (viewKinds + loaded-modules manifest) + feeds the selector. Tests: logic + controller + selector + app-store CRUD (1246 pass), typecheck 0, biome clean (only pre-existing config infos pending a future migrate), build OK. --- src/features/chat/index.ts | 7 + src/features/chat/model-select.test.ts | 49 ++++ src/features/chat/model-select.ts | 70 ++++++ src/features/chat/store.svelte.ts | 16 ++ src/features/chat/ui.test.ts | 141 ++++++++++- src/features/chat/ui/ModelSelector.svelte | 198 ++++++++++++---- src/features/named-agents/index.ts | 64 +++++ src/features/named-agents/logic/auto-save.test.ts | 157 +++++++++++++ src/features/named-agents/logic/auto-save.ts | 138 +++++++++++ src/features/named-agents/logic/normalize.test.ts | 78 +++++++ src/features/named-agents/logic/normalize.ts | 68 ++++++ src/features/named-agents/logic/options.test.ts | 72 ++++++ src/features/named-agents/logic/options.ts | 84 +++++++ src/features/named-agents/logic/snapshot.test.ts | 35 +++ src/features/named-agents/logic/snapshot.ts | 33 +++ src/features/named-agents/logic/types.ts | 57 +++++ src/features/named-agents/logic/validate.test.ts | 58 +++++ src/features/named-agents/logic/validate.ts | 47 ++++ src/features/named-agents/ui/NamedAgentCard.svelte | 120 ++++++++++ .../named-agents/ui/NamedAgentsView.svelte | 123 ++++++++++ src/features/named-agents/ui/controller.svelte.ts | 257 +++++++++++++++++++++ src/features/named-agents/ui/controller.test.ts | 237 +++++++++++++++++++ src/features/tabs/tabs-store.svelte.ts | 10 + src/features/tabs/tabs.ts | 40 +++- 24 files changed, 2102 insertions(+), 57 deletions(-) create mode 100644 src/features/named-agents/index.ts create mode 100644 src/features/named-agents/logic/auto-save.test.ts create mode 100644 src/features/named-agents/logic/auto-save.ts create mode 100644 src/features/named-agents/logic/normalize.test.ts create mode 100644 src/features/named-agents/logic/normalize.ts create mode 100644 src/features/named-agents/logic/options.test.ts create mode 100644 src/features/named-agents/logic/options.ts create mode 100644 src/features/named-agents/logic/snapshot.test.ts create mode 100644 src/features/named-agents/logic/snapshot.ts create mode 100644 src/features/named-agents/logic/types.ts create mode 100644 src/features/named-agents/logic/validate.test.ts create mode 100644 src/features/named-agents/logic/validate.ts create mode 100644 src/features/named-agents/ui/NamedAgentCard.svelte create mode 100644 src/features/named-agents/ui/NamedAgentsView.svelte create mode 100644 src/features/named-agents/ui/controller.svelte.ts create mode 100644 src/features/named-agents/ui/controller.test.ts (limited to 'src/features') diff --git a/src/features/chat/index.ts b/src/features/chat/index.ts index 8cf776b..6de8164 100644 --- a/src/features/chat/index.ts +++ b/src/features/chat/index.ts @@ -6,12 +6,19 @@ export type { } from "../../core/chunks";
