Wire a fifth pull hook so peer messages also surface between todo
items, not only at user prompts and subagent stops. While here,
extend the manual `install-hook` CLI so it patches the full plugin
hook set (SessionStart/UserPromptSubmit/SubagentStop/TaskCompleted/
SessionEnd) instead of only UserPromptSubmit, mirroring what the
plugin's hooks.json registers. Mailbox name is auto-derived from
stdin, so --name is no longer required.
Also corrects stale docs that claimed SessionStart auto-bootstraps
the watcher — push delivery has been opt-in since the
mailbox-collaborate skill landed.
The SessionStart announce no longer forces a watch-loop bootstrap on every session — it now emits a short pointer instructing Claude to invoke the new mailbox-collaborate skill (or /collaborate slash command) when the user wants peers to wake them mid-task. Messages still surface on the next user prompt via the UserPromptSubmit hook even without the watcher, so nothing is lost; idle sessions just stop burning relaunch tokens.
The watch-loop protocol (exit codes, rename handling, mail handling) moves from the hook prose into the new skill body, where it only loads when actually needed.

Fold daemonError into SessionAnnounceOptions so the helper owns the
mutually-exclusive choice between peer list and daemon-down hint. Before
this fix, a session-announce against an unreachable daemon emitted both
"No other mailboxes seen within the last 60 minutes (0 total registered)."
(misleading — the daemon was never asked) AND the daemon-unreachable hint.
Now only the hint appears when the daemon is down.

Mailbox names are now built as <project>-<session-short>, where <project>
is the sanitized git-repo basename (or cwd basename) — no more env-var
prefix step. Sessions can re-tag themselves at runtime via the new
mcp__mailbox__rename tool (POST /v1/rename), which transfers all
pending messages to the new name in a single transaction. Peers using
the old name re-discover via list_mailboxes.
BREAKING: \$CLAUDE_MAILBOX_NAME is no longer read. Existing setups that
relied on the env-var prefix should remove it from .claude/settings.json;
the prefix now comes from the working directory automatically.

session-announce now calls /v1/list with the session's X-Mailbox header,
which both registers the session with the daemon and returns all known
mailboxes in one round-trip. The output appends an "Active peers" block
listing mailboxes seen within the last hour (configurable via
--peer-window-minutes), capped at 10 entries by default. Self is
filtered out; the list is sorted most-recent-first.
So when the user says "I started a second session, coordinate with it",
Claude already has the peer's mailbox name in context — no manual
list_mailboxes call needed.
The peer-formatting logic is extracted into formatActivePeerList for
unit testing; CLI tests now pin --url to an unreachable port to keep
assertions stable on machines that have a real daemon running.
The hook now derives a unique mailbox name from the session_id supplied
on hook stdin, so two parallel Claude Code sessions in the same project
get distinct mailboxes (e.g. `claude-a8b3c1d2`, `claude-d4e5f6a7`)
instead of colliding on a shared env value. An optional
CLAUDE_MAILBOX_NAME base prefix flavors the names as `<base>-<sid>`.
Adds:
- `claude-mailbox session-announce` subcommand for the new SessionStart
hook, which prints the current session's mailbox name to context
- `/claude-mailbox:mailbox-update` slash command for `npm update` +
daemon restart
- stdin parsing helpers (parseHookStdin, deriveSessionName) with unit
tests; the doctor no longer needs a mandatory name prompt
Adds `install-hook` / `uninstall-hook` subcommands that idempotently patch
~/.claude/settings.json (or .claude/settings.json with --project), plus a
`--hook` flag on `check` that emits human-readable output and stays silent
on empty inbox or unreachable daemon.
