The daemon's two wire parsers each accept peer-controlled input without a ceiling on what a single message can turn into. Binary frames: the parser reads a 32-bit declared payload length and waits for that many bytes. A peer that declares 4 GiB makes the parser buffer every byte it sends, unbounded, with no frame ever completing. FRAME_MAX_PAYLOAD existed but was only enforced on the send path. Reject from the header instead: a declared length over the cap is unsatisfiable, so there is nothing to wait for. NDJSON: a line under the 16 MiB cap can still expand into an object graph far larger than its wire size. 4 MiB of nested arrays parses into ~109 MiB of heap — 27x amplification, and the cap admits that per line, repeatedly. Scan the line's structure before JSON.parse and reject amplified input on token count and nesting depth, so the ceiling covers what the message costs in memory rather than only what it costs on the wire. The parser also accumulates into a byte buffer rather than a JS string, which lets it report the admitted byte count without re-serializing the parsed value. Verified: 1,123 daemon tests pass; 4,782 across shared + daemon + cli, three consecutive runs. Realistic daemon PTY traffic (20k messages, 40 MiB, 64 KiB socket reads) parses at 795 MiB/s, well above real load.

Features
Also in the box:
- Quick open — Search across worktrees, files, agents, commands, and repo context without leaving your flow.
- Account switcher & usage tracking — See Claude and Codex usage and rate-limit resets, and hot-swap accounts without re-logging in.
- Rich repo previews — Preview Markdown, images, PDFs, and repo docs in the workspace.
- Computer Use — Let agents operate desktop apps and visible UI when a workflow needs real interaction.
- Notifications and unread state — Know when an agent finishes or needs attention, then mark threads unread to come back later.
- And many, many more — we ship daily, so this list is perpetually behind. The changelog is the real feature list.
