[0.1.6] — 2026-05-28

🐛 Critical fix — Bash tool calls were always reporting "error"

The Rust output structs (ReadOk, EditOk, BashOk) returned fields in snake_case (exit_code, lines_total, diff_preview) while the TS wrappers read them in camelCase. Result: r.exitCode was always undefined, so undefined !== 0 made every Bash tool result render with a red ✕ error badge — even when the underlying command had exit code 0. Read + Edit silently dropped diff previews + line totals for the same reason.

Fixed by adding #[serde(rename_all = "camelCase")] on the three output structs. Glob and Grep were already single-word fields, no change needed.

Polish carry-over

  • Keyboard shortcuts: ⌘N starts a new session, ⌘, opens Settings, ⌘/ opens About. New src/lib/keyboard.ts helper.
  • Switching project now clears chat history so the next message runs against the fresh cwd (was: old conversation lingered with new project context).

[0.1.5] — 2026-05-28

Polish + dead-code removal

  • Composer + menu wired. Click + → popover with three actions: Attach file (opens native file picker, inserts @<absolute-path> into the textarea), Slash command (prepends /), Memory note (prepends #). Replaces the previously-disabled + button.
  • Plugins toggle works. Click the switch on any plugin → writes to settings.disabledPlugins[] so the change survives restart and the agent picks it up on the next turn. Optimistic UI with rollback on failure.
  • Dead code removed. Deleted unused screens (FilePanel.tsx — Monaco file panel not surfaced in new shell; legacy Chat.tsx stub; Nav.tsx — only the type was needed, moved to src/types/screens.ts; Terminal.tsx — xterm side-pane wasn't wired in). Trimmed deps: removed @monaco-editor/react, monaco-editor, @xterm/*, tailwindcss, postcss, autoprefixer — none referenced any more.
  • ScreenName type moved to src/types/screens.ts (single source of truth for App.tsx + InspectorRail).

[0.1.4] — 2026-05-28

Robustness + polish

  • React error boundary wraps the entire app. Uncaught render errors now show a recoverable error panel ("DeepCode crashed") with the stack trace + reload button, instead of leaving the user with a blank dark window.
  • Unhandled promise rejection logger added at app entry so devtools surfaces async errors that would otherwise vanish.
  • System messages redesigned — thin centered hint instead of a row with avatar + author label. Looks much less like an interruption.
  • Bundles release.yml Tauri rewrite + docs/RELEASING.md from 0.1.3.

[0.1.3] — 2026-05-28

Visual redesign — phase 2

  • All 7 utility screens (Sessions / Plugins / Skills / Permissions / MCP / Settings / About) redesigned to match docs/VISUAL_DESIGN.html. New shared Screen + Card + Row primitives.
  • About is now a proper hero card with brand mark + gradient text
    • status diagnostics + docs links (replacing the boxed table layout the user shared as visually off-spec).
  • Settings has a GUI/JSON segmented toggle: GUI shows a quick reference + filterable flat table; JSON shows a live-validated textarea. Save persists to ~/.deepcode/settings.json (was view-only).
  • Permissions Save now actually persists rules (was stubbed).
  • Sessions has search + click-to-resume with relative time.
  • Plugins surfaces trust badges + custom Toggle switches.
  • Skills has 2-column filter-list + SKILL.md preview.
  • MCP uses status badges + tool count + inline error tail.

Release pipeline (M9)

  • release.yml rewritten for Tauri (was Electron-era). Tag → CI → npm publish + signed/notarized DMG + GitHub Release with notes.
  • docs/RELEASING.md explains the 6 secrets needed and step-by-step.

[0.1.2] — 2026-05-28

Fixes — caught from user playtest of 0.1.1

  • Tool input field-name fix. tool_write (and read / edit / bash / glob / grep) were failing with missing required key filePath when DeepSeek emitted snake_case keys but the wrapper expected camelCase. All 6 Mac tool wrappers now accept either case via a tolerant pickStr / pickNum / pickBool helper.
  • Project folder picker. First launch now shows a "Pick a project folder" overlay before chat. The chosen path is persisted to ~/.deepcode/settings.json#projectPath and threaded into every agent turn as cwd. Sidebar shows the active project + a ⇄ switch button.
  • Session persistence. Each turn now writes a JSONL session under ~/.deepcode/sessions/<id>.jsonl. Sidebar refreshes after every turn so newly-started sessions appear in the Today bucket.
  • Mid-turn controls locked. Mode / model / effort dropdowns disable while the agent is responding or awaiting approval (was previously freely switchable mid-turn).
  • Inspector rail buttons work. All 6 rail icons now route to their respective screens (Plan → Permissions, Sessions, Plugins, Skills, MCP, About, Settings). Expand-chevron ‹ still deferred.

UX improvements

  • Proper dropdowns for mode / model / effort — click-popover with inline descriptions and meta annotations, replacing the brittle click-to-cycle pattern.
  • 5 official mode options surfaced (default / acceptEdits / plan / dontAsk / bypassPermissions) instead of 3.
  • ReplScreen carries projectPath through to the system prompt so the LLM knows where it's working.

[0.1.1] — 2026-05-28

Visual redesign — phase 1

Major UI overhaul aligning the desktop client to docs/VISUAL_DESIGN.html. Phase 1 covers the three highest-traffic surfaces: Onboarding, Sessions sidebar, and the main Chat / REPL view. Other six screens land in 0.1.2.

  • Design tokens. DeepSeek brand blue (#4D6BFE) + soft (#E8EDFF) + mint accent (#14E4A2) + dark-mode neutral palette baked into CSS vars
  • Brand mark. Elephant SVG logo (matches the design spec's gradient brand badge) replaces the previous emoji-free placeholder
  • 3-column desktop shell. 240 px sessions sidebar | 1 fr chat main | 48 px inspector rail (collapsed by default). Inspector rail shows Plan badge, context-usage dot, recent files, session info, settings.
  • Chat redesign. Tool calls are now bordered cards with action · target · status-badge head + tc-body for output/diff. Inline diff uses diff-add / diff-del colors. Approval buttons (Approve / Reject / Always allow) appear immediately under the relevant tool card — never at screen bottom.
  • Composer redesign. New rounded box with toolbar (+ menu / mic / mode badge / model picker / send) and a context-usage bar showing tokens used + estimated cost.
  • Onboarding redesign. Hero gradient + big brand mark + gradient text headline matching the design spec.

Conversation flow

  • Carries over the dangerouslyAllowBrowser: true fix from 0.1.0 so the OpenAI SDK's browser-environment guard doesn't trip in the Tauri webview
  • Surfaces full error stack traces in the chat stream when the agent loop throws — easier to diagnose API key / network issues from inside the app

[0.1.0] — 2026-05-28

Mac client + CLI baseline

  • CLI: agent loop, 30+ slash commands, MCP support, plugin system, sandbox, hooks, modes, skills, sub-agents, output styles, effort levels, headless -p mode
  • Desktop (Tauri): 9 screens (Onboarding / REPL / Sessions / Plugins / Skills / Permissions / MCP / Settings / About), real runAgent in renderer, Tauri auto-updater wired to GitHub Releases, xterm.js terminal, Monaco file panel with Source / Diff / History
  • M7/M8 polish: inline approval UI with Always-allow persistence, /rewind 5-op snapshot rollback, DEEPCODE_EFFORT_LEVEL env var, desktop effort selector, Vim-mode wiring in composer, cron daemon install/uninstall scripts
  • Apple notarization: signed + notarized + stapled DMG (4.2 MB Apple Silicon)
  • VS Code extension + LSP server calling the real runAgent
