watchdeck shows every Claude Code session on your machine as a live map: every tool call, who decided it (your deny rules, Claude Code's auto check, you, the OS sandbox), and what was stopped. A denial becomes a rule in one click, written into Claude Code's own settings, so the next session never asks again. Local, private, one binary; nothing leaves your machine.

Why I built it: Claude Code's own controls are good, but each decision lives inside one session and disappears with it. I wanted one place that keeps every decision across sessions and projects, shows me what needs a rule, and writes that rule where Claude Code reads it. Where Claude Code has no control at all, scripts that skills run, MCP servers, named commands, watchdeck runs them in an OS sandbox (Seatbelt on macOS, bubblewrap on Linux) with no network and no access to credential paths unless you grant it.

What it does, concretely:

- A dashboard (`watchdeck` opens it): Home says whether you are protected and what needs you; Sessions is the map of every session, live, with a timeline per session; Rules is everything that limits an agent on this machine, strongest first, with an add sheet that previews the file it will write. - A hook on Bash and the file tools that adds a few milliseconds per call (median 6.2 ms on my M-series Mac in the runs before the v0.1.0 tag, measured before every release and checked in CI). - Leak watch: if a secret-shaped string shows up in a tool result or a reply, Home tells you where, never the secret itself. - `watchdeck doctor --prove` runs the hook you installed against a built-in canary in a throwaway HOME and reports five checks, so "it is enforced" is something you can see.

What it does not do, up front: it cannot stop prose. A `SKILL.md` can still talk the model into misusing Read or WebFetch; only scripts are sandboxed. Network is on or off per subject; no hostname filtering yet. In my own headless study (18 sessions, three models, three scenarios), no planted marker leaked, but three WebFetch calls went around a refused `curl` untouched, so I added rules that cover every route to a host or a path with one intent. macOS is verified end to end; Linux passes CI but has not run on a developer machine. No Windows.

Releases are reproducible, signed (keyless cosign bundle), attested (GitHub build provenance), with an SBOM per archive, and the installer can verify all of that before it installs anything. Apache-2.0.

Install: `curl -fsSL https://raw.githubusercontent.com/Panda-Taps-LLC/watchdeck/m... | sh` or `brew install Panda-Taps-LLC/tap/watchdeck`, then `watchdeck setup`. Remove it with `watchdeck uninstall`.

The ask: tell me what you see on your machine that it should have caught, and what rule you wanted that it could not write. I will answer every issue.

Windows

Each story opens in a window holding its article above its discussion; drag the bar between them to share the room differently. A window can be moved by its title bar, resized from any edge, snapped to a half or a corner by dragging it there, maximised, or minimised to the bar at the foot of the page. Use Window > New reader window to open an empty reader, or Story > Open in new reader window to open another reader for the current article. Docked readers keep their articles when you select another story from the sidebar. Minimized readers can be restored and reused for their site. A window's Previous and Next buttons read up and down the list in the same window.

A link in a comment or an article to another Hacker News or Lobsters thread opens that thread in a window too. A link to a single HN comment opens the comment above its replies.

While a story's window is in front, the Story and Discussion menus in the menu bar hold its commands: pinning, Previous and Next story, sorting, collapsing every thread, jumping to the first new comment. Each window also remembers where you were in its article and discussion, so a reload, or Back to a story that Next took you past, finds your place again. Closing a window forgets it.

The whole arrangement lives in the address, so a bookmark or a shared link brings it back, and Back undoes the last change. Moving between Hacker News, Lobsters, their lists, Pinned and Find changes only the list, and leaves the windows open.

The list

The pin at the start of a row keeps the story in Pinned, and the cross at its end hides it. Pinned can be narrowed by words in the title, site or author, by source, and to the stories you haven't opened yet, and ordered by when you pinned them, by points or by comments; the filters are part of the address, so a filtered view can be bookmarked. Scroll past the end of the list to load more. Domain filters, in the View menu, hide every story from a site.

Collections are named lists of stories. Story > Add to collection files the story in front into one or more of them, and the Collections feed shows them all or one at a time; the menu that chooses collections also creates, renames, and deletes them. A note is your own text on a story. Choose Add note in a story's toolbar to write one; it saves as you type. Rows with a note carry the note mark, and the Notes feed lists every noted story and searches the text of your notes.

Browsing view

View > Windowed and View > Classic select the browsing view and save your default in this browser. Window view reuses a reader for each feed. Classic view opens stories and applets as pages. Open as a page is a one-off action that does not change your saved default. Use the Windowed selector to return an article to a window. Direct page links always open as pages.

Applets

The Applets menu in the menu bar holds three tools, each a window of its own. Replies to me takes your Hacker News user name and lists the replies to your last thirty comments and stories, checking again every three minutes while it is open, and marking what is new since you last marked them read. Look up a user opens a profile on Hacker News or Lobsters, with their submissions and recent comments, as a commenter's name in any discussion does; the bar at the top of a profile looks up someone else in the same window, and Back returns to the one before. Who is hiring? filters the posts of HN's monthly hiring threads by the words you type.

They read only what the sites publish to everyone, so none of them asks for a login, and your user name stays in this browser anonymously and is included in retained applet state when signed in.

Find

Find takes any link and lists every time it was submitted to Hacker News and Lobsters, so you can read each discussion of it.

About

YAVCHN never sees your Hacker News or Lobsters login. The discussion is fetched from each site's public API; to vote or reply, follow the link above the discussion, or the arrow beside a comment, to the source's own site. Without a YAVCHN account, your data stays in this browser. When signed in, pins, collections, notes, blocked domains, and retained reading state are stored with your account and synchronized across devices. Hidden stories and layout stay in this browser. The privacy policy has the details.
