João Salavisa f3daeaf416 feat(cli-mode): forward Preview chat input to PTY in passthrough sessions (#1042)
* feat(cli-mode): route Preview chat input through PTY stdin in passthrough sessions

Branch Executor.Prompt on lifecycle.Manager.IsPassthroughSession so that
follow-up prompts from any UI surface (the kanban Preview screen, mobile
session view, etc.) reach the running CLI agent via PTY stdin instead of
silently falling through to the ACP path. WritePassthroughStdin failures
propagate so Service.handlePromptError reverts session state and surfaces
the error; MarkPassthroughRunning failures are non-fatal because the data
is already in the PTY.

Closes the backend half of #989; the Preview-side UI compose box ships
in a follow-up commit.

* feat(cli-mode): add Preview-screen compose box for passthrough sessions (#989)

In the kanban Preview tab, render a small kandev-controlled composer below
the PassthroughTerminal when the session is is_passthrough. Submitting (Enter
or click) posts message.add over WS — the backend's Executor.Prompt routes
passthrough sessions to PTY stdin so the CLI agent actually receives it.
Shift+Enter inserts a newline; empty/whitespace input is disabled.

This closes #989 together with the previous backend commit.

* fix(cli-mode): warn when dropping attachments on passthrough prompts

Code review found that a passthrough prompt carrying non-empty text and
attachments silently dropped the attachments — surprising for any UI
surface (e.g. the full-page TaskChatPanel) that lets users attach images
to a passthrough task. The plan flagged this exact "silent drop" risk.
Pass attachments into promptPassthrough and log a warning with the
count when any are dropped; empty-text-with-attachments still errors
out as before. Adds a regression-guard test.

* test(cli-mode): cover passthrough composer routing end-to-end

QA pass added integration-level tests at the Service.PromptTask layer
that exercise the full wiring (real Service + real Executor, with a
mocked agent manager) for the three issue-#989 acceptance paths:
prompt-routes-to-PTY, empty-prompt-surfaces-error, and write-failure-
reverts-session. Also adds a unicode/multiline preservation guard at
the Executor.Prompt unit layer. Lives in a new file to avoid pushing
task_operations_test.go over the file-length-limit threshold.

* fix(cli-mode): preserve composer text on send failure + clarify dispatchOnly

Addresses two pieces of PR #1042 review feedback.

1. PassthroughComposer used to clear the textarea unconditionally after
   onSubmit resolved, but the WS handler swallowed transport errors and
   resolved normally — so a network blip silently wiped the user's typed
   message with no way to retry. Add a passthrough-specific send handler
   that rethrows after toasting, and gate the setValue("") in the composer
   on success. Preserves the ACP handler's swallow-and-resolve contract
   to avoid leaking unhandled rejections into the TaskChatPanel chain.
   New regression test: "preserves the typed text when onSubmit rejects".

2. Add a one-line comment at the passthrough branch in Executor.Prompt
   explaining why dispatchOnly is not forwarded — PTY writes are inherently
   fire-and-forget, so the flag has no analogue.

* fix(cli-mode): toast disconnect + auto-grow passthrough composer textarea

Two follow-ups from PR #1042 review on commit e403ca8e.

1. handleSendPassthroughMessage threw when getWebSocketClient() returned
   null without surfacing a toast first — Composer.submit's catch then
   preserved the typed text but the user had no idea why the send didn't
   land (greptile P1, cubic P2). Toast a "Not connected" error before
   re-throwing so the failure is visible.

2. PassthroughComposer textarea stayed 36px tall on Shift+Enter multiline
   input because rows={1} + resize-none + only a CSS-based field-sizing
   hint meant non-Chromium browsers never grew the box (Claude UX
   suggestion). Add a useLayoutEffect that resets and re-measures
   scrollHeight on every value change, capped at max-h-32 (128 px) with
   overflow-y-auto for content that exceeds the cap.

What

Organize work across kanban and pipeline views with opinionated workflows and execute multiple tasks in parallel. Assign agents from any provider, and review their output in an integrated workspace - file editor, file tree, terminal, browser preview, and git changes in one place. Terminal agent TUIs are great for running agents, but reviewing and iterating on changes there doesn't scale.

Run it locally or self-host it on your own infrastructure and access it from anywhere via Tailscale or any VPN.

Open source, multi-provider, no telemetry, not tied to any cloud.

Vision

Humans stay in control. Define tasks, build agentic workflows with gates, review every change, decide what ships.

  • Review-first - Humans support production systems. We need to understand (yet) and trust the code that gets deployed.
  • Your workflow - Every team is different, and not every developer uses AI the same way. Define workflows once, share them across the team, and give everyone a consistent process for working with agents - regardless of experience level.
  • Remote agents - Running multiple agents on a large codebase can quickly saturate a local machine. The goal is a single control plane: offload execution to servers, orchestrate from anywhere, including your phone.

Features

  • Multi-agent support - Claude Code, Codex, GitHub Copilot, Gemini CLI, Amp, Auggie, OpenCode, Cursor, Qwen, Factory Droid, iFlow, Kilocode, Pi, Kimi, AWS Kiro, Qoder, Trae
  • Parallel task execution – start and manage multiple tasks from different sources simultaneously, boosting productivity with AI agents
  • Integrated workspace - Built-in terminal, code editor with LSP, git changes panel, embedded vscode and chat in one IDE-like view
  • Kanban task management - Drag-and-drop boards, columns, and workflow automation
  • Agentic workflows - Multi-step pipelines that mix-and-match agents per step - for example, Claude Code Opus to design a plan, GitHub Copilot Sonnet to implement it, and Codex GPT 5.4 to review the changes. See docs/workflows.md
  • Sub-tasks - Agents can spawn sub-tasks that resume from the parent task's session. Useful for splitting a task that has grown too big, or producing several PRs from the same starting point.
  • CLI passthrough - Drop into raw agent CLI mode for direct terminal interaction with any supported agent, leverage the full power of their TUIs
  • Workspace isolation - Git worktrees prevent concurrent agents from conflicting
  • Multi-repository tasks - Span a single task across multiple repositories, with one worktree per repo, per-repo branches, per-repo PRs, and per-repo grouping in the Changes panel and review dialog
  • Flexible runtimes - Run agents as local processes, in isolated Docker containers or in remote executors like sprites.dev
  • Session management - Resume and review agent conversations
  • Stats - Track your productivity with stats on the completed tasks, agent turns, etc

Integrations

All agents communicate via ACP (Agent Client Protocol). Some agents support ACP natively, while others use ACP adapter packages that bridge their native protocols. CLI Passthrough mode is also available for direct terminal interaction with any agent CLI. If your agent isn't supported yet, open an issue or submit a PR with the integration. See Adding a New Agent CLI for a step-by-step guide.

Bring your own TUI agents

There is support for running any agent as TUI inside a terminal. Just add the cli command in the agent profile settings and the task will start the agent inside a PTY terminal instead of using ACP.

Supported Executors

Executor Description
Local Process Runs the agent as a local process on the host machine
Docker Runs the agent in an isolated Docker container
Sprites Runs the agent in a remote cloud environment via sprites.dev

Each executor uses git worktrees for workspace isolation, preventing concurrent agents from conflicting.

Quick Start

Homebrew (macOS, Linux)

brew install kdlbs/kandev/kandev
kandev

NPX

npx kandev@latest

Requires npm 7+. Installs the CLI plus a platform-matched runtime bundle in one step.

NPM (global)

npm install -g kandev@latest
kandev

Updates

  • brew upgrade kandev
  • npx kandev@latest (always uses the latest published version)
  • npm install -g kandev@latest

The worktrees and sqlite db live in ~/.kandev by default. Works on macOS, Linux, and Windows (WSL or native).

From Source

# Clone the repository
git clone git@github.com:kdlbs/kandev.git
cd kandev

# Start in production mode
make start

Prerequisites: Go 1.26+, Node.js 18+, pnpm, Docker (optional - needed for container runtimes)

High level architecture

    end

    subgraph W2[Docker Container]
        Agent2[Agent CLI] --- WT2[Worktree]
    end

We also want to add support for these remote runtimes:

  • Remote SSH - run agents on remote servers over SSH, using docker or local processes with workspace isolation
  • K8s operator - run agents in a Kubernetes cluster, with auto-scaling and resource management.

Comparison to Other Tools

There are a few similar tools in this space, and new ones appearing everyday. Here's what sets this one apart:

  • Server-first architecture - Not a desktop app. Runs as a server you can access from any device, including your phone. Start a task away from your computer and check in on it later.
  • Remote runtimes - Run agents on remote servers and Docker hosts, not just your local machine.
  • Multi-provider - Use Claude Code, Codex, Copilot, Gemini, Amp, Auggie, OpenCode, Cursor, Qwen, Droid, iFlow, Kilocode, Pi, Kimi, Kiro, Qoder, and Trae side by side. Not locked to one vendor.
  • CLI passthrough and chat - Interact with agents through structured chat messages or drop into raw CLI mode for full agent TUI capabilities.
  • Open source and self-hostable - No vendor lock-in, no telemetry, runs on your infrastructure.
