An assistant message with an empty or whitespace-only text content block —
produced by context compression or certain tool-call flows — is rejected by
the Anthropic Messages API with HTTP 400 "text content blocks must contain
non-whitespace text". Because the blank block is stored in session history and
replayed verbatim every turn, the session is permanently wedged behind the same
400.
The Bedrock adapter already guards this via _safe_text() (#9486); the native
Anthropic path never got the same treatment. _sanitize_replay_block() rebuilt
text blocks with the raw stored text, and the _convert_assistant_message()
guard only caught a fully empty block list, not a list still containing a
whitespace-only text block.
Add a _safe_text() helper mirroring the Bedrock one and apply it at both points:
the ordered-blocks replay path and a final in-place walk of the converted
content list. Both are self-healing — sessions that stored blank blocks recover
on the next API call. Only text blocks are coerced; thinking/tool_use/image
blocks are untouched.
Fixes#69512
The renderer showed two assistant bubbles for one turn — a partial
streamed copy plus the clean final copy (#63679). A reload fixed it, so
the persisted transcript was correct; this was live reconciliation.
Root cause is in completeAssistantMessage (use-message-stream/index.ts).
message.interim fires for BOTH verify-on-stop candidates AND ordinary
tool-call turns (tui_gateway _load_interim_assistant_messages), and the
interim seal clears streamId + sets interimBoundaryPending. So at
message.complete the streamId fast-path is skipped and it enters the
fallback. There the settle-onto-interim branch was gated on
responsePreviewed — true ONLY for verify-on-stop. A normal tool-call
turn whose final text matched its sealed interim satisfied neither
settle branch and fell through to append a brand-new bubble. Two rows,
distinct ids, id-based dedup cannot collapse them → renders twice.
Fix: settle onto the sealed interim whenever the final CONTINUES it —
final == interim, final starts with interim (streamed + trailing delta),
or interim starts with final (streaming dropped characters). This is
gated on existing.interim so it only ever collapses a genuine sealed
interim, and a genuinely DIFFERENT final still appends as its own
bubble. responsePreviewed is retained as an OR so the verify-on-stop
continuation-budget case (final text rewritten, no shared prefix) still
settles as before.
The prior test that asserted a non-previewed identical interim+final
produced TWO bubbles was encoding the bug; rewritten to assert one.
Added coverage: prefix-extended non-previewed final collapses; a
genuinely different final still appends (no over-collapse).
Community analysis on the issue (seedSeenBubbleKeys / kind-guard) was
against a pre-refactor v0.7.0 bundle — those symbols no longer exist;
this is the current-code root cause.

Gateway tests construct GatewayRunner via object.__new__ without __init__;
the new #51899 guard accessed self.config directly and crashed those
runners (AttributeError). Use getattr with None default — the guard
no-ops without config, matching the documented object.__new__ pitfall.
Note: #51899's commit was authored as a placeholder identity
(hermes-agent@example.invalid); it was re-stamped to @byshubham's
numeric noreply on this branch, so no mapping file is needed. Other
salvaged commits use GitHub noreply addresses.
Two related Slack delivery fixes for send_message text sends:
- Route Slack text delivery through _send_via_adapter so the live
in-process gateway adapter (multi-workspace aware, channel→client
mapping, adapter-side gates) is preferred, with the plugin's
_standalone_send as the out-of-process fallback — matching how the
media path already behaves.
- _standalone_send: SLACK_BOT_TOKEN can be a comma-separated list in
multi-workspace installs and slack_tokens.json carries OAuth
per-workspace tokens; the standalone Web-API path used to send the
literal comma-joined string, which Slack rejects as invalid_auth.
Try each token individually, retrying on token-scoped errors
(invalid_auth / not_in_channel / channel_not_found …) and stopping on
terminal ones. User-DM resolution (U…/W… targets) also tries each
token.
Adapted from #47547 by @replygirl — the original patched the legacy
tools/send_message_tool.py::_send_slack helper, which moved to the
Slack plugin's _standalone_send in #41112.

Previously, Slack sessions and the channel directory stored raw channel
IDs (e.g. C0ATFHY907L) as chat_name, making it impossible for operators
to identify channels in send_message listings or session data.
Changes:
- Add _channel_name_cache and _resolve_channel_name() to SlackAdapter
that calls conversations.info (channels) or users.info (DMs) with
in-memory caching to avoid repeated API calls
- Use resolved names in _handle_slack_message() build_source() calls
- Use cached names in _seed_assistant_thread_session()
- Enrich session-sourced entries in channel_directory._build_slack()
by cross-referencing API results and falling back to conversations.info
+ users.info for DMs and private channels not in the bot's scope
Fixes: channel directory and session origins now show readable names
like 'general' or 'John Doe' instead of 'C0xxx' / 'D0xxx'.
Follow-up to the #51899 pick, folding in the config-bridge half of the
competing PR #46925 (@bhanusharma, earliest submitter for the
ignored-channel gate):
- _apply_yaml_config: translate config.yaml slack.ignored_channels into
SLACK_IGNORED_CHANNELS (list or CSV), env-var-wins like every other
bridged Slack key.
- SlackAdapter._slack_ignored_channels / gateway.run's
_slack_ignored_channels_from_gateway_config: fall back to the
SLACK_IGNORED_CHANNELS env var when PlatformConfig.extra carries no
value, so top-level slack: blocks (which flow through the env bridge,
not extra) are honored at both the adapter and runner gates.
- conftest: force-clear SLACK_ALLOWED_CHANNELS / SLACK_IGNORED_CHANNELS /
SLACK_DISABLE_DMS between tests (config-loader side-effect leak class).
- Tests: env-bridge translation + precedence in test_config.py, env
fallback + extra-wins in test_slack_runner_ignored_channels.py.
Credit: #46925 by @bhanusharma proposed the same gate with the YAML→env
bridge; #51899 (picked as the base) carries the wider outbound/runner
coverage. Closes#46925 as consolidated here with first-submitter credit.
Add --long-description / --long-description-file to `hermes slack
manifest` so the generated app manifest can carry Slack's
display_information.long_description (175–4,000 characters), with
validation of the length bounds, mutual-exclusion with --slashes-only,
and UTF-8 file input. Also propagate the manifest command's exit status
through cmd_slack so validation failures reach the shell.

PR #37303 added per-platform streaming defaults and the commit message
explicitly called out "Discord/Slack/etc. only have edit-based streaming
(repeated editMessage), which flickers and is noticeably jankier" — but
only discord.streaming=false was shipped. Slack uses the same edit-based
streaming mechanism and has the same flicker problem, yet it was left to
follow the global switch (default true when streaming is enabled).
Add "slack": {"streaming": False} to DEFAULT_CONFIG["display"]["platforms"]
alongside the Discord default. The same deep-merge semantics apply: a user
who explicitly sets display.platforms.slack.streaming: true keeps their
value unchanged. The dashboard schema gains a slack.streaming toggle
automatically since it is generated from DEFAULT_CONFIG.
Update test_per_platform_streaming_defaults.py to cover slack in all
existing assertions and rename the resolver test to reflect both platforms.
Hermes already identifies itself on outbound calls to model providers
and monitoring endpoints — see hermes_cli/models.py and
plugins/model-providers/gmi/__init__.py
("Attribution so GMI can identify traffic from Hermes Agent"). The
Slack adapter is the one outbound surface that doesn't carry the
same identifier, so HermesAgent-driven Slack traffic is
indistinguishable from any other Bolt-Python app at the Slack
platform layer.
This sets `user_agent_prefix=f"HermesAgent/{_HERMES_VERSION}"` on the
AsyncWebClient instances constructed in gateway/platforms/slack.py
and threads them through AsyncApp via its `client` kwarg. Both
kwargs are first-class in slack-sdk and slack-bolt; no new
dependencies. Resulting header looks like:
HermesAgent/<version> Python/3.x slackclient/3.x ...
No behavioral change for users — the Slack API ignores User-Agent
semantically; it lands in logs and analytics. Reversible.
Tests in tests/gateway/test_slack.py:
- TestSlackUserAgent pins the prefix shape and runs connect()
end-to-end (multi-token config) to assert every AsyncWebClient
carries the prefix and AsyncApp receives the pre-built client.
- TestSlackProxyBehavior fakes updated to tolerate the new kwargs
via **_kwargs so they don't break on future passthroughs.
.get("key", {}) only applies the default when the key is ABSENT.
When the key exists with value None (null in JSON), .get() returns
None and the subsequent .get() raises AttributeError.
Fix: replace .get("key", {}).get(...) with (.get("key") or {}).get(...)
which handles both missing keys AND None values.

Blank (or whitespace-only) answers to the home-channel prompt in the
interactive setup wizards previously left any previously saved
*_HOME_CHANNEL / *_HOME_ROOM env value in place, so operators could not
clear a stale home channel by re-running setup. Strip the prompt input
and call remove_env_value() on blank answers across the Discord, Slack,
Feishu, Matrix, Mattermost, WeCom and WhatsApp plugin setup wizards,
with per-adapter wizard tests covering set/clear/whitespace flows.

Salvaged from #58421
The C13 log-noise test (merged while this branch was in flight) builds a
bare SlackAdapter without __init__; the new _channel_teams ambiguity map
crashed it. getattr-guard, same pattern as the sibling defensive inits.
Five regression tests for _resolve_download_token and the download
helpers: explicit team wins, URL-embedded team id routes to the owning
workspace, unknown/no-match fall back to the primary token, and an
end-to-end _download_slack_file_bytes call asserts the Authorization
header carries the owning workspace's token.
A/B: all five fail with the fix commit reverted, pass with it applied.
Salvaged from #59742 (downloads half only). Main already resolves the
event-level team id from the channel→workspace cache before downloads
(the file-EVENT half was covered by #30456), but when neither the event
nor the cache knows the workspace, both download helpers silently fell
back to the PRIMARY workspace token — Slack then returns an HTML login
page instead of file bytes for any non-primary workspace file.
Slack private file URLs embed the owning workspace id
(files-pri/<TEAM_ID>-<FILE_ID>/...), so _resolve_download_token now
prefers: explicit team_id -> URL-embedded team id -> primary token.
Both _download_slack_file and _download_slack_file_bytes route through
it.
Deferred from #59742 (out of this correctness cluster's scope): the
channel→team disk persistence, the pre-send conversations.info probe
loop, and the thread-file ingestion feature.
Reapplied from #59742 by @benjamin2026-dot onto the current adapter
(original targeted the pre-#30456 download sites).
Conflict-resolution follow-up composing #68925 (Bob) with the already-
applied #20583/#66398 (jordanhubbard) recovery design:
- #68925's caller-level second _query_recoverable_session pass (via
lookup_session_key=) referenced a variable that no longer exists —
the legacy exact-key fallback now lives INSIDE
_query_recoverable_session, which also claims the legacy key once per
process and rewrites the peer row to the scoped key. Drop the dead
caller-level pass.
- Keep #68925's _recovered_row_matches_source_scope origin guard wired
into both recovery paths: a scoped channel lookup refuses rows whose
recorded origin names another workspace (or no workspace at all).
- Routing-index migration adoption policy documented at the site:
origin names a workspace -> exact match only; scope-less DM -> first
workspace claims once; scope-less channel -> refuse.
