- Atomic delivery: create the temp file inside the destination dir (dot-prefixed, invisible to the inbox glob) so the final rename never crosses filesystems and readers never see a half-written message. - Reject . and .. explicitly in the --reply-to and coord-done name guards instead of relying on downstream failure. - Add -h/--help to coord-inbox.sh (uniform across the three CLIs). - Close selftest gaps: default mailbox path via HOME fallback, malformed frontmatter on the read path, read-only destination dir. 48 -> 64 checks, all green.

# coord-inbox.sh - read this repo's PENDING inbox + unseen broadcasts from the
|
|
# local coordination mailbox (~/.claude/coord), print them formatted for
|
|
# injection with per-message reply/resolve hints.
|
|
#
|
|
# IDEMPOTENT by design: directed messages are NOT archived on read - they stay
|
|
# pending and are re-injected on every SessionStart (startup, /clear, resume)
|
|
# until marked handled with coord-done (so /clear never loses them, and this is
|
|
# safe to re-run manually mid-session). Broadcasts are delivered once per repo
|
|
# via a per-repo seen set. Prints nothing (exit 0) when nothing is pending.
|
|
# ASCII only, bash 3.2 safe.

# Usage: coord-inbox.sh [--repo <name>]
