 ### Changes
 - macOS: strip prerelease/build suffixes when parsing gateway semver patches. (#1110) — thanks @zerone0x.
 - macOS: keep CLI install pinned to the full build suffix. (#1111) — thanks @artuskg.
-- CLI: add `channels capabilities` to summarize channel support and provider probes.
+- CLI: add `channels capabilities` with provider probes (Discord intents, Slack scopes, Teams Graph).
 
 ### Fixes
 - Doctor: avoid re-adding WhatsApp ack reaction config when only legacy auth files exist. (#1087) — thanks @YuriNachos.

 Notes:
 - `--channel` is optional; omit it to list every channel (including extensions).
 - `--target` accepts `channel:<id>` or a raw numeric channel id and only applies to Discord.
-- This probes provider APIs where possible (Discord intents, Telegram webhook, Slack auth test, Signal daemon); channels without probes report `Probe: unavailable`.
+- Probes are provider-specific: Discord intents + optional channel permissions; Slack token scopes; Telegram bot flags + webhook; Signal daemon version; MS Teams app token + Graph roles/scopes when available. Channels without probes report `Probe: unavailable`.
