* fix(runner): surface dangling-symlink errors instead of misleading EEXIST

When a session's workspace path is a symbolic link to a directory that no
longer exists, the runner previously failed with a kernel-level error:

    Unable to create directory at '/path'. System error: EEXIST: file
    already exists, mkdir '/path'.

The cause: `fs.access` follows symlinks and throws ENOENT when the target
is missing, then the fallback `fs.mkdir(dir, { recursive: true })` cannot
tolerate the existing non-directory entry (the dangling symlink itself)
and surfaces EEXIST verbatim. Users had no way to tell that the symlink
target was the actual problem.

Replace the inline `fs.access` + `fs.mkdir` pair with a small
`validateWorkspaceDirectory` helper that uses `fs.lstat` so symlinks are
inspected without being followed, then explicitly handles:

- missing path -> approval flow / mkdir as before
- existing directory -> ok
- regular file at the workspace path -> "non-directory file" error
- symlink to existing directory -> ok
- symlink to a non-directory -> "not a directory" error
- dangling symlink -> diagnostic naming both the symlink path and the
  missing target, with recovery options (recreate the target, remove
  the symlink, archive the session)

The mkdir error switch is preserved (EACCES, ENOTDIR, ENOSPC, EROFS) and
extended with an EEXIST race-recheck that lstat's the path again so the
kernel error code never leaks to the user.

Adds focused unit tests for both the fs-touching paths (real tmpdir +
symlinks) and the pure errno-to-message mapper.

Closes #890

* fix(runner): drop copy-pasteable rm command from dangling-symlink hint

The dangling-symlink recovery message embedded the user-controlled
workspace path inside a literal `rm '...'` shell command shape. A path
containing a single quote would break the quoting and turn the
diagnostic into a shell-injection / accidental-delete vector when the
user copy-pasted the suggested command.

Describe the recovery action in prose instead ("remove the dangling
symlink at '<path>'") so the path is no longer presented as a
copy-pasteable command. Adds a regression test that exercises a path
containing a single quote and asserts the message never contains the
literal `rm ...` shape.

* fix(runner): preserve ENOTDIR diagnostic on lstat parent-path failure

When the workspace path sits under a regular-file parent, fs.lstat throws
ENOTDIR before mkdir runs. Route that through describeMkdirError so the
user still sees the historic "file already exists at this path" message
instead of the generic inspect-workspace-path text.

hapi CLI

Run Claude Code, Codex, Cursor Agent, Gemini, or OpenCode sessions from your terminal and control them remotely through the hapi hub.

What it does

  • Starts Claude Code sessions and registers them with hapi-hub.
  • Starts Codex mode for OpenAI-based sessions.
  • Starts Cursor Agent mode for Cursor CLI sessions.
  • Starts Gemini mode via ACP (Anthropic Code Plugins).
  • Starts OpenCode mode via ACP and its plugin hook system.
  • Provides an MCP stdio bridge for external tools.
  • Manages a background runner for long-running sessions.
  • Includes diagnostics and auth helpers.

Typical flow

  1. Start the hub and set env vars (see ../hub/README.md).
  2. Set the same CLI_API_TOKEN on this machine or run hapi auth login.
  3. Run hapi to start a session.
  4. Use the web app or Telegram Mini App to monitor and control.

Commands

Session commands

  • hapi - Start a Claude Code session (passes through Claude CLI flags). See src/index.ts.
  • hapi codex - Start Codex mode. See src/codex/runCodex.ts.
  • hapi codex resume <sessionId> - Resume existing Codex session.
  • hapi cursor - Start Cursor Agent mode. See src/cursor/runCursor.ts. Supports hapi cursor resume <chatId>, hapi cursor --continue, --mode plan|ask, --yolo, --model. Local and remote modes supported; remote uses agent -p with stream-json.
  • hapi gemini - Start Gemini mode via ACP. See src/agent/runners/runAgentSession.ts. Note: Gemini runs in remote mode only; it waits for messages from the hub UI/Telegram.
  • hapi opencode - Start OpenCode mode via ACP. See src/opencode/runOpencode.ts. Note: OpenCode supports local and remote modes; local mode streams via OpenCode plugins.
  • hapi resume [sessionId] - List resumable sessions for this machine or resume one locally.

Resume a remote session locally

hapi resume
hapi resume <session-id>

hapi resume lists resumable sessions for the current machine. hapi resume <session-id> hands off an active remote session and opens the same HAPI session in the local terminal.

Authentication

  • hapi auth status - Show authentication configuration and token source.
  • hapi auth login - Interactively enter and save CLI_API_TOKEN.
  • hapi auth logout - Clear saved credentials.

See src/commands/auth.ts.

Runner management

  • hapi runner start - Start runner as detached process.
  • hapi runner stop - Stop runner gracefully.
  • hapi runner status - Show runner diagnostics.
  • hapi runner list - List active sessions managed by runner.
  • hapi runner stop-session <sessionId> - Terminate specific session.
  • hapi runner logs - Print path to latest runner log file.

Both start and start-sync accept repeatable --workspace-root <path> (or --workspace-root=<path>). When set:

  • The web /browse page surfaces scoped file trees rooted at those paths.
  • The runner refuses list-directory and spawn-session requests for paths outside the configured roots.
  • ~ and ~/foo are expanded.

Omitting the flag keeps the legacy behavior: no scoping, no /browse feature.

See src/runner/run.ts.

Diagnostics

  • hapi doctor - Show full diagnostics (version, runner status, logs, processes).
  • hapi doctor clean - Kill runaway HAPI processes.

See src/ui/doctor.ts.

Other

  • hapi mcp - Start MCP stdio bridge. See src/codex/happyMcpStdioBridge.ts.
  • hapi hub - Start the bundled hub (single binary workflow).
  • hapi server - Alias for hapi hub.

Configuration

See src/configuration.ts for all options.

Required

  • CLI_API_TOKEN - Shared secret; must match the hub. Can be set via env or ~/.hapi/settings.json (env wins).
  • HAPI_API_URL - Hub base URL (default: http://localhost:3006).

Optional

  • HAPI_HOME - Config/data directory (default: ~/.hapi).
  • HAPI_EXPERIMENTAL - Enable experimental features (true/1/yes).
  • HAPI_EXTRA_HEADERS_JSON - JSON object of extra headers to send on CLI → hub requests, e.g. {"Cookie":"CF_Authorization=..."}.
  • HAPI_CLAUDE_PATH - Path to a specific claude executable.
  • HAPI_HTTP_MCP_URL - Default MCP target for hapi mcp.

Runner

  • HAPI_RUNNER_HEARTBEAT_INTERVAL - Heartbeat interval in ms (default: 60000).
  • HAPI_RUNNER_HTTP_TIMEOUT - HTTP timeout for runner control in ms (default: 10000).

Worktree (set by runner)

  • HAPI_WORKTREE_BASE_PATH - Base repository path.
  • HAPI_WORKTREE_BRANCH - Current branch name.
  • HAPI_WORKTREE_NAME - Worktree name.
  • HAPI_WORKTREE_PATH - Full worktree path.
  • HAPI_WORKTREE_CREATED_AT - Creation timestamp (ms).

Storage

Data is stored in ~/.hapi/ (or $HAPI_HOME):

  • settings.json - User settings (machineId, token, onboarding flag). See src/persistence.ts.
  • runner.state.json - Runner state (pid, port, version, heartbeat).
  • logs/ - Log files.

Requirements

  • Claude CLI installed and logged in (claude on PATH).
  • Cursor Agent CLI installed (agent on PATH) for hapi cursor. Install: curl https://cursor.com/install -fsS | bash (macOS/Linux), irm 'https://cursor.com/install?win32=true' | iex (Windows).

  • Bun for building from source.

Build from source

From the repo root:

bun install
