v0.5.0 — Agents pane: match the best of Claude Code & Codex

Added — Agents pane "match the best of Claude Code & Codex" initiative

Driven by a 6-agent deep-dive on Claude Code, Codex, Cursor, Windsurf,
Aider, Cline, Continue.dev, Zed, Copilot Workspace, JetBrains Junie, and
Warp; followed by a 4-agent deep-dive on the OpenAI "Codex for (almost)
everything" April 16 release + GPT-5.5 + CLI 0.107→0.128 cuts.

Tier 1 — visible polish

• Drag-drop and clipboard-paste images in the launcher (5 MB cap, removable thumbnail chips); image blocks land in the SDK content array on send
• SessionHealthBar in chat header: model · context % gauge · cumulative tokens · session $ · git branch
• Mid-turn steering: Tab queues a follow-up; Alt+. / Alt+, nudge the model toward thorough / fast within the same provider
• Shift+Tab cycles a single mode chip (default | plan | manual | yolo)
• New slash commands /usage, /history, /review, /goal, /template; saved prompt templates surface as native /<slug> commands
• Header context badges: provider auth, linked Mission with click-to-jump, MCP N/M server toggle dropdown, memory-context tooltip previewing the actual injected patterns
• One-time onboarding overlay on first Agents-view visit

Tier 2 — killer features

• Persistent dockable PlanPanel parsing Anthropic SDK TodoWrite and the markdown task_list tool
• PendingApprovalsRollup with "Apply / Reject / Cancel all" when 2+ pending writes or permissions stack up
• /review spawns a Reviewer subagent fed a unified diff of the parent conversation's pending writes — returns 🛑 Blockers / ⚠️ Concerns / 💡 Nits
• Durable agent profiles (Default / Scout / Reviewer built-ins, plus user-created); AgentProfilesCard editor in Settings → Agent Profiles
• AGENTS.md / CLAUDE.md auto-injection from the project root
• Memories panel inline editor (edit text + category, Ctrl+Enter saves)
• RunningAgentsChip in toolbar with live count of streaming agents, click-to-jump and stop

Tier 3 — sidecar protocol v3 → v4 + frontend

• Sidecar PROTOCOL_VERSION bumped 2 → 4
• New events: plan_block (structured TodoWrite mirror), tool_output_extended (Bash exit code + stdout/stderr; Write/Edit modified paths), turn_summary (running tokens between turns)
• New requests: set_permission_mode, set_model, retry, cancel_pending_tools (drains parked permission/edit prompts as denied without killing the loop)
• StartSessionRequest gains attachments and resume; EditResponseRequest gains mergedContent (per-hunk acceptance honored sidecar AND every in-process provider)
• permission_request gains batchId/batchSize for grouped rollups
• done payload gains resumeToken; persisted on the conversation
• Auto-failover heuristic on rate-limit (Opus → Sonnet → Haiku, o3 → gpt-5 → o4-mini, MiniMax → highspeed) with a one-retry-per-turn guard
• Worktree-per-conversation toggle in launcher (.pkt-worktrees/<convId> on a fresh pkt/<convId> branch)

Codex Spring 2026 absorption (A1–A5 + B1–B9)

• Codex todo_list items map to the existing plan_block event so PlanPanel works for Codex too
• reasoning_tokens + cached_input_tokens from usage flow through turn_summary and roll into aggregateConversationCost (was: under-reporting GPT-5.5 spend)
• Codex MultiAgentV2 sub-agent attribution: turn_summary.address (/root/agent_a etc.) routes child tokens into a per-address bucket on the conversation; CostDashboard rolls every bucket into the total
• AGENTS.md cascading resolver in Rust core (core::agents_md) walking ~/.claude/AGENTS{.override,}.md → git-root → cwd, picking one of AGENTS.override.md / AGENTS.md / CLAUDE.md per directory, concat with <!-- source: <path> --> headers, capped at 32 KiB. Honors CLAUDE_HOME env override for CI parity with Codex's CODEX_HOME
• ProjectRulesCard in Settings → Project Rules reads + writes both AGENTS.md and CLAUDE.md on save; surfaces a Unify affordance when the two files diverge; offers a starter template when neither exists
• Hover-+ Codex-App-style diff comments: per-line + button in ToolDiffView opens an inline composer; queued comments fold into the next user turn as a File comments: preamble
• Smart-approval prefix-rule proposal: PermissionPrompt gains a fourth row "Always allow rule <pattern>"; one click writes the derived pattern into conversation.allowedTools
• Composer-mode segmented control (Local / Worktree / Cloud) replaces the binary worktree toggle; persisted via localStorage
• Right-rail tabbed mode (AgentTabbedRail) with Plan / Diff / Inspector tabs in a single 340 px column; toggleable from chat header
• Persistent goals bridged to Missions: new goalStore + /goal slash command + goal-bound footer in PlanPanel (Pause / Resume / Complete) + 🎯 N badge per Mission row
• LiveSpendChip in toolbar combining today's persisted total (analyticsStore) + live in-memory session $ across every open API conversation
• Old-model pinning per profile via pinnedModel field; resolves as profile.pinnedModel ?? selectedModel ?? getDefaultModel(agent) at launch
• Plan-with-Claude → Execute-with-Codex one-click handoff: PlanPanel "Hand off to Codex →" button when parent is Claude AND Codex auth is ready; spawns a fresh Codex conversation seeded with buildHandoffPrompt(parent) (distilled spec + plan + discussion summary, capped at 12 KiB); parentConversationId field wires a "← back to plan" link in the child's chat header

Follow-ups (F1–F10)

• Auto-resume hydrated conversations: extracted listener block into installApiAgentListeners helper; sendMessage routes the first post-restart send through resumeApiConversation with the stored resumeToken
• In-process providers honor mergedContent for per-hunk diff acceptance (parity with sidecar Anthropic)
• Anthropic sidecar emits tool_output_extended (Bash exit code + stdout/stderr; Write/Edit modifiedPaths) and turn_summary (running per-message tokens for live SessionHealthBar updates)

Fixed

• macOS title bar shows native traffic-light controls — config switched to decorations: true + titleBarStyle: "Overlay" + hiddenTitle: true; lib.rs setup hook strips decorations at runtime on Windows + Linux so the custom chrome stays the only chrome there. TitleBar.tsx detects macOS via userAgent, hides the Win-style min/max/close cluster, reserves 78 px of left padding for the traffic-light area
• Standalone target/<profile>/packetade.exe reported "Sidecar down" — two stacked bugs:
  • Capability gate: app.shell().sidecar("node") is rejected by Tauri's permission layer unless an explicit shell:allow-execute entry lists node with sidecar: true (added in 74e6ba9)
  • Per-triple Node binary missing: Tauri's shell plugin on Windows resolves sidecar("node") to <exe_dir>/node-<target-triple>.exe, not generic node.exe; build.rs now copies binaries/node-<triple>.<ext> into the cargo output directory at compile time (added in 8f49083)

Removed

• .github/workflows/{build,ci,release}.yml — builds and releases run locally; no GitHub Actions CI in this repo

Sidecar protocol

• PROTOCOL_VERSION = 4. v4 added cancel_pending_tools request. v3 added typed attachments on start_session / send_message, mergedContent on edit_response, batchId/batchSize on permission_request, resumeToken on done, plus plan_block / tool_output_extended / turn_summary events. Old sidecars reply "Unknown request type" to v3+ requests; supervisor warns on version mismatch (does not refuse)

v0.2.0 — Agents parity + FlightDeck split

PacketCode v0.2.0

Headline

• Agents pane parity push — plan mode (Shift-Tab style read-only), permission prompts (Auto / Ask / Allow / Deny), extended thinking with streaming display, accept/reject inline diffs for write_file, retry last turn, collapsible tool results, per-turn cost pill, custom slash commands, parallel tool execution, conversation persistence and markdown export, checkpoints backend.
• Cross-provider cost tracking — unified Cost Dashboard aggregating Claude CLI + Codex CLI + all 5 API agents (Claude / OpenAI / MiniMax / OpenRouter / Ollama) with source filter + per-turn pricing tables.
• Opus 4.7 model support — selectable in Claude CLI, Anthropic API, and OpenRouter provider lists.
• TUI extracted — the packetcode-tui binary moved to its own sibling repo, FlightDeck. PacketCode is now GUI-only.
• Docs + landing page refresh — full user manual, updated landing page, TUI mentions cleaned from marketing.

Included artifacts

• packetcode.exe — portable GUI binary (28.4 MB).
• PacketCode_0.2.0_x64-setup.exe — NSIS installer (6.9 MB).

Install

Run the NSIS installer, or drop the portable packetcode.exe wherever you want and run it.

Agents BYOK setup

The new API agents require you to bring your own API keys. Open Tools → API Keys and add at least one: Claude, OpenAI, MiniMax, OpenRouter, or Ollama (local).

Terminal alternative

If you want a TUI-first experience, see the FlightDeck sibling repo — same Flights / orchestration model, pure Ratatui.
