impl Attributable for RpcApprovalChannel

fn role(&self) -> Role

fn alias(&self) -> &str

impl Channel for RpcApprovalChannel

fn supports_free_form_ask(&self) -> bool

Free-form text elicitation is Phase 2 of the elicitation rollout — the same answer as AcpChannel. Until that lands, tools like ask_user (with no choices) and escalate_to_human (with wait_for_response) fail fast on the Code tab.

fn name(&self) -> &str

Human-readable channel name

fn send<'life0, 'life1, 'async_trait>( &'life0 self, _message: &'life1 SendMessage, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

fn listen<'life0, 'async_trait>( &'life0 self, _tx: Sender<ChannelMessage>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Start listening for incoming messages (long-running)

fn request_approval<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, recipient: &'life1 str, request: &'life2 ChannelApprovalRequest, ) -> Pin<Box<dyn Future<Output = Result<Option<ChannelApprovalResponse>>> + Send + 'async_trait>>

fn request_choice<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, question: &'life1 str, choices: &'life2 [String], timeout: Duration, ) -> Pin<Box<dyn Future<Output = Result<Option<String>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

where 'life0: 'async_trait, Self: 'async_trait,

Check if channel is healthy

fn send_choice<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, recipient: &'life1 str, prompt: &'life2 str, options: &'life3 [(String, String)], ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

fn stop_typing<'life0, 'life1, 'async_trait>( &'life0 self, _recipient: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Stop any active typing indicator.

fn supports_draft_updates(&self) -> bool

Whether this channel supports progressive message updates via draft edits.

fn supports_outbound_send(&self) -> bool

Whether send actually delivers a message OUTBOUND on this channel. Default true. An INBOUND-ONLY transport (e.g. an AMQP trigger source whose send is a deliberate no-op that returns Ok) overrides this to false, so a surface that must genuinely deliver - such as the SOP approval route adapter - can refuse to route to it (and report the misconfiguration) instead of silently succeeding without sending anything.

fn self_handle(&self) -> Option<String>

Self-loop guard for multi-agent runs: the bot’s own handle/identity on this channel, so the orchestrator can drop inbound events whose sender matches. A bot must never respond to its own messages, even if a misconfigured peer group lists the bot’s handle as an external peer.

fn self_addressed_mention(&self) -> Option<String>

The exact form the bot expects when addressed by users on this channel (e.g. Discord <@snowflake>, Telegram @bot_username). Returned verbatim into the per-channel system prompt. Default None for channels with no inbound mention concept. Channels that override self_handle should usually override this too.

fn drop_self_messages(&self, msg: &ChannelMessage) -> bool

Whether the orchestrator should drop an inbound message as self-authored (multi-agent self-loop guard). Default compares msg.sender against Self::self_handle case-insensitively after stripping a leading @ from each side. Override only for platforms whose identity comparison is non-string.

fn forge_request<'life0, 'async_trait>( &'life0 self, _request: ForgeApiRequest, ) -> Pin<Box<dyn Future<Output = Result<ForgeApiResponse, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

fn is_direct_message(&self, _msg: &ChannelMessage) -> bool

Whether an inbound message is a direct one-to-one conversation with the bot. A DM is definitionally addressed to the bot, so the orchestrator skips the reply-intent classifier and goes straight to the tool-capable agent turn. Default false: channels that cannot prove a one-to-one context keep the classifier precheck.

fn supports_multi_message_streaming(&self) -> bool

Whether this channel supports multi-message streaming delivery.

fn multi_message_delay_ms(&self) -> u64

Minimum delay (ms) between sending each paragraph in multi-message mode.

fn send_draft<'life0, 'life1, 'async_trait>( &'life0 self, _message: &'life1 SendMessage, ) -> Pin<Box<dyn Future<Output = Result<Option<String>, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Send an initial draft message. Returns a platform-specific message ID for later edits.

fn update_draft<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, _recipient: &'life1 str, _message_id: &'life2 str, _text: &'life3 str, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait, Self: 'async_trait,

Update a previously sent draft message with new accumulated content.

fn update_draft_progress<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, _recipient: &'life1 str, _message_id: &'life2 str, _text: &'life3 str, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait, Self: 'async_trait,

Show a progress/status update (e.g. tool execution status).

fn finalize_draft<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, _recipient: &'life1 str, _message_id: &'life2 str, _text: &'life3 str, _suppress_voice: bool, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait, Self: 'async_trait,

Finalize a draft with the complete response (e.g. apply Markdown formatting). suppress_voice forces text delivery even on voice-only peers.

fn cancel_draft<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _recipient: &'life1 str, _message_id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Cancel and remove a previously sent draft message if the channel supports it.

fn add_reaction<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, _channel_id: &'life1 str, _message_id: &'life2 str, _emoji: &'life3 str, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait, Self: 'async_trait,

Add a reaction (emoji) to a message.

fn remove_reaction<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, _channel_id: &'life1 str, _message_id: &'life2 str, _emoji: &'life3 str, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait, Self: 'async_trait,

Remove a reaction (emoji) from a message previously added by this bot.

fn pin_message<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _channel_id: &'life1 str, _message_id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Pin a message in the channel.

fn unpin_message<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _channel_id: &'life1 str, _message_id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Redact (delete) a message from the channel.

fn create_room<'life0, 'life1, 'async_trait>( &'life0 self, _options: &'life1 RoomCreationOptions, ) -> Pin<Box<dyn Future<Output = Result<String, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Create a new platform room/conversation when the channel supports it.

fn invite_user<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _room_id: &'life1 str, _user_id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Invite a user to an existing platform room/conversation.

fn request_approval_attributed<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, recipient: &'life1 str, request: &'life2 ChannelApprovalRequest, ) -> Pin<Box<dyn Future<Output = Result<Option<AttributedApprovalResponse>, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Like Channel::request_approval, but also reports which back-channel produced the decision when this channel fans the request out. Default delegates to Channel::request_approval with decided_by: None; only a fan-out bridge needs to override.

fn send_gate_prompt<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _recipient: &'life1 str, _prompt: &'life2 ChannelGatePrompt, ) -> Pin<Box<dyn Future<Output = Result<bool, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Present a long-lived, out-of-band gate prompt (e.g. a parked SOP approval) on this channel, rendered natively — an embed with one button per choice on Discord, an inline keyboard on Telegram, and so on.

fn finalize_gate_prompt<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _reference: &'life1 str, _outcome: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<bool, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Mark a previously sent gate prompt as resolved: strip its interactive controls and replace the body with outcome (e.g. “Approved by @user — run resumed”), so a decided gate cannot be clicked again and the decision is visible in place. reference is the same correlation key the prompt was sent with. Best-effort: Ok(false) when this channel has nothing to finalize (no native prompt, or the mapping was lost to a restart) — the gate state itself is never affected.
