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.

Delivers peer messages that arrive during a long-running subagent into the
parent context the moment the Task tool returns, instead of waiting until
the next user prompt. Reuses the existing `claude-mailbox check --hook` so
the mailbox identity stays consistent with UserPromptSubmit.
Plugin 1.2.0 → 1.3.0.

47822 collided with ClaudeDo.Worker.exe on at least one user's machine.
37849 is high, registered to nobody, and avoids the prior conflict.
Both the Node port and the .NET port move together (still
wire-compatible). Defaults change only — if a user has a custom port
in mailbox.json, that stays.
Two production-readiness fixes so colleagues can install cleanly:
1. Plugin's MCP server now spawns `claude-mailbox mcp-stdio`, a small
stdio MCP wrapper that proxies tool calls to the daemon's REST API.
Claude Code does not support env-var substitution in HTTP MCP `url`
fields (issue #46889), so the wrapper is the only way to make the
daemon URL configurable per machine via CLAUDE_MAILBOX_URL.
2. Windows `install-autostart` now falls back from `schtasks /Create`
to an HKCU\Software\Microsoft\Windows\CurrentVersion\Run entry
when Group Policy blocks the Scheduled Task path. Both modes are
per-user, no admin, persist across logoffs. The chosen mode is
recorded in ~/.claude-mailbox/autostart-mode so status/start/stop/
uninstall-autostart pick the right cleanup path.
Also bumps the npm version to 1.0.1 to align with the published 1.0.0
plus this patch.
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.
MCP tools (send/check_inbox/peek_inbox/list_mailboxes) now accept the
caller's mailbox name as an explicit argument (from/name), falling back
to the X-Mailbox header for legacy single-session HTTP setups. This
unblocks multi-session coordination through a shared .mcp.json — each
Claude session passes its own session-derived name on every call,
instead of relying on a single transport header that all sessions
would share.
The plugin now ships .mcp.json (no header), and the SessionStart
announcement spells out the exact args to pass to each mcp__mailbox__*
tool so Claude wires it up automatically.
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
The doctor command runs entirely inside Claude Code and walks through:
binary install via npm, daemon autostart, mailbox-name prompt with write
to per-project `.claude/settings.json` env, and a self → self smoke test.
Also adds `/claude-mailbox:mailbox-status` as a read-only health check.
Reduces the colleague onboarding to: add marketplace, install plugin,
run the doctor — no terminal context-switch required.
Adds a /plugin marketplace at the repo root and a `claude-mailbox` plugin under
plugin/ that wires the UserPromptSubmit hook without needing the per-user
`install-hook` step. The hook command (`claude-mailbox check --hook`) now reads
the mailbox name from $CLAUDE_MAILBOX_NAME when --name is omitted and emits a
one-line setup hint when the daemon is unreachable, so a missing daemon is loud
instead of invisible.
The plugin only contains the Claude Code glue — the daemon binary is still a
separate prerequisite (`npm i -g @kuns/claude-mailbox` + install-autostart),
and the plugin/README plus main README spell out the three-step setup.
