YAML loads a bare numeric value such as
discord:
free_response_channels: 1491973769726791812
as an int. _discord_free_response_channels() / _slack_free_response_channels()
checked `isinstance(raw, list)` and `isinstance(raw, str)` in that order and
then fell through to `return set()`, so a single-channel config that happened
to be unquoted was silently dropped with no log line — the bot kept demanding
@mentions even though the channel was configured to free-response.
A multi-channel value like `1234567890,9876543210` does not trip this because
the comma forces YAML to parse it as a string. Single-channel configs are
the only case that breaks, which is exactly the footgun that's hardest to
diagnose (the config "looks right" and the feature just doesn't activate).
Note that the old-schema env-var bridge at gateway/config.py:614+ already
runs `str(frc)` when forwarding to SLACK_/DISCORD_FREE_RESPONSE_CHANNELS,
so the env-var fallback worked. The bug only surfaces on the
`config.extra["free_response_channels"]` path populated by the `platforms:`
bridge at gateway/config.py:576, which passes the raw YAML value through
unchanged.
Fix at the reader: treat any non-list value as a scalar, coerce with str(),
then apply the same CSV split semantics. This keeps the public contract
stable (list or str-like continues to work identically) while accepting
the ints that the YAML loader is free to hand us.
Added tests for both Discord and Slack covering:
- bare int value in config.extra
- list of ints in config.extra
Extends the strict_mention feature so an @mention in strict mode no
longer persistently tags the thread as 'mentioned'. Without this, the
thread's first mention would permanently auto-trigger the bot on every
subsequent message — which is exactly what strict_mention is designed
to prevent. Closes the agent-to-agent ack loop hole hhhonzik identified
in #14117.

Adds a strict_mention config option that, when enabled, requires an
explicit @-mention on every message in channel threads. Disables the
'once mentioned, forever in the thread' and session-presence auto-triggers.
- New _slack_strict_mention() helper (config.extra + SLACK_STRICT_MENTION env)
- Bridged top-level slack.strict_mention yaml to SLACK_STRICT_MENTION env,
matching require_mention/allow_bots bridging
- Unit tests for the helper + config bridge
Top-level channel messages arrive at _resolve_thread_ts with
metadata.thread_id set to the message's own ts, because the inbound
handler in _handle_message_event uses 'event.ts' as a session-keying
fallback when event.thread_ts is absent. That made metadata alone
insufficient to distinguish a real thread reply from a top-level
message, so reply_in_thread=false only took effect in DMs.
Use reply_to (== incoming message_id == ts for top-level messages) as
the tiebreaker: when metadata.thread_id == reply_to the 'thread' is the
synthetic session-keying fallback, not a real parent, so we reply
directly in the channel. Real thread replies (reply_to != thread_id)
still resolve to the parent thread and preserve conversation context.
Closes#9268.
Port the mention gating pattern from Telegram, Discord, WhatsApp, and
Matrix adapters to the Slack platform adapter.
- Add _slack_require_mention() with explicit-false parsing and env var
fallback (SLACK_REQUIRE_MENTION)
- Add _slack_free_response_channels() with env var fallback
(SLACK_FREE_RESPONSE_CHANNELS)
- Replace hardcoded mention check with configurable gating logic
- Bridge slack config.yaml settings to env vars
- Bridge free_response_channels through the generic platform bridging loop
- Add 26 tests covering config parsing, env fallback, gating logic
Config usage:
slack:
require_mention: false
free_response_channels:
- "C0AQWDLHY9M"
Default behavior unchanged: channels require @mention (backward compatible).
