Conversation
Edge is Chromium and already spoke the same protocol, so the only Chrome-specific code was the default-profile lookup. Add a --browser flag (chrome|edge, env CHROME_BROWSER) that selects the vendor path table, and make the DevToolsActivePort error name the right browser and inspect URL instead of always saying Chrome. Channel aliases stay vendor-scoped (--channel chrome only for Chrome, edge only for Edge), and Edge Canary on Linux is rejected outright rather than resolved to a directory that cannot exist. Supporting a second browser exposed a pre-existing correctness bug: the daemon was keyed only to the uid and bound to whichever endpoint the first command resolved, so every later --browser/--user-data-dir flag was silently ignored. A Chrome-bound daemon would happily answer --browser edge commands and return Chrome's results. Key each daemon by a hash of its resolved ws URL instead. Chrome, Edge, each channel and each headless instance now get their own daemon and can be driven concurrently. The URL's browser GUID changes per launch, so a restarted browser gets a fresh daemon rather than inheriting a dead connection; the orphan exits on its existing idle timeout. Two notes on the implementation: - The lock file is deliberately NOT keyed. It only serializes the brief write-pid-then-bind window, and lock files are never removed, so a per-instance lock would accumulate a file per browser session forever. - The new info sidecar is another predictable name in shared /tmp, so write_pid_file_checked is generalized to write_private_file_checked (O_NOFOLLOW, O_NONBLOCK, mode 0600, deferred truncate) rather than using fs::write, which follows symlinks. kill-daemon is now target-scoped, so `--browser edge kill-daemon` cannot stop the Chrome daemon. --all stops every daemon for the user and is the only way to clear one whose browser has already exited, since a scoped kill has no endpoint left to resolve. --all also sweeps the pre-key chrome-devtools-daemon-<uid>.pid name so an upgrade does not strand an unreachable daemon. Add list-daemons (PID, browser, endpoint, uptime, state; --json supported). It reads only on-disk state, so it works when every browser has exited, and flags rows whose PID is dead as stale. Docs: the skill's "one daemon per user, bound to one Chrome" warning was backwards after this change, and the headless recipe's bare kill-daemon calls would have killed the user's daemon rather than the throwaway one — both corrected, and the recipe now warns that a temp profile is not automatically isolated in Edge, whose first-run import pulls open tabs and extensions from the default browser. Also documented that remote debugging is enabled by the persistent chrome://inspect/#remote-debugging toggle (edge://inspect for Edge), stored as devtools.remote_debugging.user-enabled, not only by a launch flag. Verified against a live Chrome and Edge at once: each command reached its own browser, scoped kill left the other daemon serving, --all cleared everything including stale and legacy files, and one lock file remained.

Review follow-ups on the per-endpoint daemon change. list-daemons special-cased Json and let --toon fall through to the text table. Route both structured formats through the existing format_structured helper instead, which already encodes TOON. The empty list stays structural in both (`[]` / `[0]:`); the "No daemons running." sentence remains text-only. kill-daemon's --all summary counted failures across keyed instances plus the legacy daemon but sized the total from keys.len(), so a legacy-only failure could report "1 of 0". Count the legacy stop as an attempt — and only when a legacy PID file was actually there, so the total does not inflate on the common path. stop_legacy_unkeyed_daemon now reports whether it found anything. Accept browser and channel names case-insensitively, trimmed, so --browser Edge and CHROME_BROWSER=EDGE work; error messages still quote the name as typed. Unknown values behave as before. That made the raw spelling visible in list-daemons, since the info file records what was passed, so the daemon label is canonicalized (--browser EDGE and --browser msedge both list as "edge"). Docs: - The kill-daemon description implied it signals and cleans up on every platform. The signal and file removal are Unix-only; Windows prints that it is unsupported and touches nothing. - Windows daemon filenames are keyed like every other platform's, so document chrome-devtools-daemon-<key>.addr rather than the pre-key name, and point the taskkill instructions at list-daemons, since there can now be several PIDs to choose between. - The skill said --channel selects stable/beta/dev/canary for Edge without noting that Edge ships no Canary for Linux, which browser.rs rejects outright. - Both scoped kill-daemon calls in the headless recipe could abort the script: a scoped kill must resolve its profile's endpoint, and there is none on a fresh profile (step 1) or after a browser that died before writing its port file (the EXIT trap). Both are now best-effort with `|| true`, still profile-scoped rather than reaching for --all, which would stop the user's own daemons. Verified: --toon and --json render structurally including when empty, alias and mixed-case spellings resolve and scope kills correctly, and the daemon table labels canonically.

Second round of review follow-ups. print_daemon_list parsed the PID file with a bare trim().parse::<u32>(), which accepts 0. daemon_pid_alive(0) then calls kill(0, 0), and signal 0 to PID 0 probes the caller's own process group rather than a daemon — it succeeds, so a PID file containing 0 listed as "running". Route the read through parse_pid_file_contents, the same validation kill-daemon applies before signalling, so 0 and values outside pid_t are rejected and the row reports an unknown PID instead. This also closes a gap between code and comment: a test already asserted that PID 0 is never probed, but nothing on this path enforced it. Docs, all three cases where a Unix-only behavior was stated as general: - The architecture diagram still showed the pre-key chrome-devtools-daemon-<uid>.sock, missed when the other daemon filenames were keyed. - list-daemons can only mark a row stale on Unix; Windows never probes liveness, so every row's state is "?" and stale never appears. - kill-daemon --all "clears every daemon" is false on Windows, where kill-daemon prints that it is unsupported and stops nothing. Scoped to Unix, with taskkill guidance for Windows. Also expand resolve_ws_url's doc comment to say why an explicit --ws-endpoint takes precedence: it names the browser directly, so it must not be second-guessed by local profile discovery, and it short-circuits --browser/--channel, which exist only to locate a profile directory. Verified: PID files containing 0, 4294967295 and non-numeric text all render as unknown rather than running, and a live daemon still lists normally.

Third round of review follow-ups. kill-daemon signalled whatever PID it read from the PID file. A daemon killed with SIGKILL leaves that file behind — cleanup is skipped by design — the OS is then free to reuse the PID for another process of the same user, and SIGTERM would land on that process instead. The --all sweep widened the exposure by walking every PID file rather than one. Verify against the live process instead of the recorded metadata. Cross- checking the PID file against the info sidecar would prove nothing: both are written by the same daemon at the same moment and go stale together. Only the daemon binds its keyed socket, and it does so under the same startup lock that wrote the PID file, so a live listener at that path is proof the recorded PID is still ours, and ECONNREFUSED is proof it is not. stop_daemon_at now probes the socket and, when nothing answers, removes the files without signalling. The probe sends nothing and drops the connection; the daemon treats that as a read error and keeps serving. A daemon wedged inside a CDP call still passes, since the kernel completes the connect from the listen backlog without the daemon accepting. Deliberate trade-off: if the socket file is deleted while the daemon is alive, kill-daemon now declines to signal and the orphan exits on its 5-minute idle timeout. Leaving an orphan that self-heals is the better failure of the two. Also: - short_endpoint stripped only ws://, so a wss:// endpoint — which --ws-endpoint accepts verbatim — rendered in list-daemons as the bare scheme "wss:". Strip either scheme. - The README described list-daemons as showing running daemons; it also shows stale entries. - Add anyhow context to the daemon connect paths (Unix socket, Windows address-file read, Windows TCP connect) and to the Windows address-file write. These surface in the user-visible "daemon unavailable" warning from run_direct_fallback. - The four path helpers in protocol.rs restated their signatures; their comments now explain what the instance key is for. Verified: a live non-daemon process recorded in a daemon PID file is no longer signalled (it was, before this), and a real listening daemon is still stopped normally.

The socket probe added in 564e746 closed the stale-PID case but not a startup race, correctly spotted in review. stop_daemon_at read the PID, probed the socket and signalled without holding any lock. A daemon can start for the same key between the read and the probe, so the read could return a stale PID the OS has since recycled while the probe sees the newcomer's listener. The listener then proves only that some daemon holds the key — not that it owns the PID already in hand — and SIGTERM lands on an unrelated process. Take daemon::lock_daemon_files() for the whole sequence, the same lock that covers PID-file creation and socket binding. The two observations become one atomic step: no daemon can have appeared since the read, so a live listener proves the PID read is that listener's. On timeout the stop fails closed, signalling nothing, and says to retry. This cannot be blocked by the case kill-daemon exists for: the daemon drops the startup lock before entering its accept loop, so a daemon wedged inside a CDP call does not hold it, and only a concurrent startup or cleanup contends. It also composes with the daemon's own exit path, where cleanup_at try_locks and backs off when contended — the dying daemon skips its file removal and the caller does it instead. The guarantee depends on run_daemon writing the PID file before binding the endpoint, both under that lock, which was an implicit coupling. Noted at that site so a reorder does not silently break kill-daemon. The race is a cross-process TOCTOU and is not reproducible from a single process, so the new test covers the enforceable half: with the lock held via a second file descriptor, stop_daemon_at must refuse, signal nothing, and leave the PID and info files in place for the retry. Verified both directions after the change: a process holding the keyed socket with its PID recorded is signalled and stopped, while a live process recorded without a listener is spared and only its files removed.

Included review availability: Your plan provides up to 2 included reviews per hour; 1 remains after this review.
Fourth round of review follow-ups. The daemon reported every CDP connection failure as "Failed to connect to Chrome" regardless of --browser. Fixing only that prefix would have made the message contradict itself, because the inner error from CdpClient::connect also hardcoded Chrome: Failed to connect to Microsoft Edge: Failed to connect to Chrome at ws://… So the label is threaded one level deeper, into CdpClient::connect — two call sites, the daemon and the direct fallback — and the now-redundant outer prefix is dropped. Adds browser::display_name for the human-readable form, which falls back to the input so a diagnostic never silently claims the wrong browser. That also corrects the message users actually read, which the review did not mention: the connect timeout said "Chrome may be waiting for a human to approve the remote-debugging connection dialog … ask the human to check Chrome". Under --browser edge that sent people to the wrong window. Five doc and help sites match "Failed to connect to Chrome" as a literal lookup key. Chrome's text still contains that exact substring, verified, so they keep working; the skill's failure-handling heading and the --force help text now say the browser name varies, so an Edge user recognises their own error. Also: - The skill described list-daemons as showing what is running; it also shows stale entries on Unix. - Remove a doc sentence duplicated onto one line in lib.rs, introduced when the startup-lock test was inserted ahead of that anchor in 8a04c9a. Verified at runtime on the daemon path, the direct path and via the msedge alias: Edge failures name Microsoft Edge, Chrome failures still contain the documented substring, and neither message repeats itself.

@coderabbitai Fourth round addressed in dd48c04 (pushed). Replies are on both threads; the nitpick wasn't inline, so it's here. Nitpick — duplicated doc sentence in On the daemon error message. The fix went a level deeper than suggested, for a reason worth noting: labelling only It also fixed a message neither of us flagged, which is the one that actually reaches users: the connect timeout told Edge users to go and check Chrome. That is the text you see when a connection stalls on a pending consent dialog, and it was pointing at the wrong window for anyone using Validation. All tests pass, One note on browser-backed verification for this PR generally: Edge on my machine is currently sitting on a remote-debugging consent dialog, a side effect of the repeated |

Tip For best results, initiate chat on the files or code changes.
The The timeout guidance now directs Edge users to Edge. This fixes the user-visible failure path during a remote-debugging consent dialog. The deterministic socket stand-in and unreachable-endpoint checks are appropriate for these daemon and connection-error paths. ✏️ Learnings added

Edge is Chromium and already spoke the same protocol, so the only Chrome-specific code was the default-profile lookup. Add a --browser flag (chrome|edge, env CHROME_BROWSER) that selects the vendor path table, and make the DevToolsActivePort error name the right browser and inspect URL instead of always saying Chrome.
Channel aliases stay vendor-scoped (--channel chrome only for Chrome, edge only for Edge), and Edge Canary on Linux is rejected outright rather than resolved to a directory that cannot exist.
Supporting a second browser exposed a pre-existing correctness bug: the daemon was keyed only to the uid and bound to whichever endpoint the first command resolved, so every later --browser/--user-data-dir flag was silently ignored. A Chrome-bound daemon would happily answer --browser edge commands and return Chrome's results.
Key each daemon by a hash of its resolved ws URL instead. Chrome, Edge, each channel and each headless instance now get their own daemon and can be driven concurrently. The URL's browser GUID changes per launch, so a restarted browser gets a fresh daemon rather than inheriting a dead connection; the orphan exits on its existing idle timeout.
Two notes on the implementation:
kill-daemon is now target-scoped, so
--browser edge kill-daemoncannot stop the Chrome daemon. --all stops every daemon for the user and is the only way to clear one whose browser has already exited, since a scoped kill has no endpoint left to resolve. --all also sweeps the pre-key chrome-devtools-daemon-.pid name so an upgrade does not strand an unreachable daemon.Add list-daemons (PID, browser, endpoint, uptime, state; --json supported). It reads only on-disk state, so it works when every browser has exited, and flags rows whose PID is dead as stale.
Docs: the skill's "one daemon per user, bound to one Chrome" warning was backwards after this change, and the headless recipe's bare kill-daemon calls would have killed the user's daemon rather than the throwaway one — both corrected, and the recipe now warns that a temp profile is not automatically isolated in Edge, whose first-run import pulls open tabs and extensions from the default browser. Also documented that remote debugging is enabled by the persistent chrome://inspect/#remote-debugging toggle (edge://inspect for Edge), stored as
devtools.remote_debugging.user-enabled, not only by a launch flag.
Verified against a live Chrome and Edge at once: each command reached its own browser, scoped kill left the other daemon serving, --all cleared everything including stale and legacy files, and one lock file remained.
