 In the CLI, cycle through these modes with `/verbose`. To use `/verbose` in messaging platforms (Telegram, Discord, Slack, etc.), set `tool_progress_command: true` in the `display` section above. The command will then cycle the mode and save to config.
 
+Tool progress requires a gateway adapter that can display progress updates safely. Platforms without message editing support, including Signal, suppress tool-progress bubbles even if `/verbose` saves a non-`off` mode.

 ### Runtime-metadata footer (gateway only)
 
 When `display.runtime_footer.enabled: true`, Hermes appends a small runtime-context footer to the **final** message of each gateway turn. The current footer can show the model, context-window percentage, and current working directory. Off by default; opt in per-gateway if your team wants every reply to include this provenance.

 ### Per-platform progress overrides
 
-Different platforms have different verbosity needs. For example, Signal can't edit messages, so each progress update becomes a separate message — noisy. Use `display.platforms` to set per-platform modes:

 Platforms without an override fall back to the global `tool_progress` value. Valid platform keys: `telegram`, `discord`, `slack`, `signal`, `whatsapp`, `matrix`, `mattermost`, `email`, `sms`, `homeassistant`, `dingtalk`, `feishu`, `wecom`, `weixin`, `bluebubbles`, `qqbot`. The legacy `display.tool_progress_overrides` key still loads for backward compatibility but is deprecated and migrated into `display.platforms` on first load.
 
+Signal is listed as a valid platform key because the setting can be saved per platform, but the current Signal adapter cannot edit sent messages and does not render tool-progress bubbles. Keep Signal `tool_progress` set to `off`; use the CLI or an editing-capable messaging platform if you need to watch each tool call live.

 `interim_assistant_messages` is gateway-only. When enabled, Hermes sends completed mid-turn assistant updates as separate chat messages. This is independent from `tool_progress` and does not require gateway streaming.

+### Tool Progress Display

+Signal does not support editing already-sent messages. Hermes therefore suppresses gateway tool-progress bubbles on Signal, even when `/verbose` is enabled and saves a non-`off` mode for the platform.

+You can still see tool activity in the CLI, and final Signal replies can include normal assistant output. If you need live per-tool progress in chat, use a messaging platform with message editing support.
