# ACP Persistent Bindings for Discord Channels and Telegram Topics
Status: Draft
## Summary
Introduce persistent ACP bindings that map:
- Discord channels (and existing threads, where needed), and
- Telegram forum topics in groups/supergroups (`chatId:topic:topicId`)
to long-lived ACP sessions, with binding state stored in top-level `bindings[]` entries using explicit binding types.
This makes ACP usage in high-traffic messaging channels predictable and durable, so users can create dedicated channels/topics such as `codex`, `claude-1`, or `claude-myrepo`.
## Why
Current thread-bound ACP behavior is optimized for ephemeral Discord thread workflows. Telegram does not have the same thread model; it has forum topics in groups/supergroups. Users want stable, always-on ACP “workspaces” in chat surfaces, not only temporary thread sessions.
## Goals
- Support durable ACP binding for:
- Discord channels/threads
- Telegram forum topics (groups/supergroups)
- Make binding source-of-truth config-driven.
- Keep `/acp`, `/new`, `/reset`, `/focus`, and delivery behavior consistent across Discord and Telegram.
- Preserve existing temporary binding flows for ad-hoc usage.
## Non-Goals
- Full redesign of ACP runtime/session internals.
- Removing existing ephemeral binding flows.
- Expanding to every channel in the first iteration.
- Implementing Telegram channel direct-messages topics (`direct_messages_topic_id`) in this phase.
- Implementing Telegram private-chat topic variants in this phase.
## UX Direction
### 1) Two binding types
- **Persistent binding**: saved in config, reconciled on startup, intended for “named workspace” channels/topics.
- **Temporary binding**: runtime-only, expires by idle/max-age policy.
### 2) Command behavior
- `/acp spawn ... --thread here|auto|off` remains available.
- Add explicit bind lifecycle controls:
- `/acp bind [session|agent] [--persist]`
- `/acp unbind [--persist]`
- `/acp status` includes whether binding is `persistent` or `temporary`.
- In bound conversations, `/new` and `/reset` reset the bound ACP session in place and keep the binding attached.
### 3) Conversation identity
- Use canonical conversation IDs:
- Discord: channel/thread ID.
- Telegram topic: `chatId:topic:topicId`.
- Never key Telegram bindings by bare topic ID alone.
## Config Model (Proposed)
Unify routing and persistent ACP binding configuration in top-level `bindings[]` with explicit `type` discriminator:
```jsonc
{
"agents": {
"list": [
{
"id": "main",
"default": true,
"workspace": "~/.openclaw/workspace-main",
"runtime": { "type": "embedded" },
},
{
"id": "codex",
"workspace": "~/.openclaw/workspace-codex",
"runtime": {
"type": "acp",
"acp": {
"agent": "codex",
"backend": "acpx",
"mode": "persistent",
"cwd": "/workspace/repo-a",
},
},
},

},
},
},
],
},
"acp": {
"enabled": true,
"backend": "acpx",
"allowedAgents": ["codex", "claude"],
},
"bindings": [
// Route bindings (existing behavior)
{
"type": "route",
"agentId": "main",
"match": { "channel": "discord", "accountId": "default" },
},
{
"type": "route",
"agentId": "main",
"match": { "channel": "telegram", "accountId": "default" },
},
// Persistent ACP conversation bindings
{
"type": "acp",

},

},
},
],
"channels": {
"discord": {
"guilds": {
"111111111111111111": {
"channels": {
"222222222222222222": {
"enabled": true,
"requireMention": false,
},
"333333333333333333": {
"enabled": true,
"requireMention": false,
},
},
},
},
},
"telegram": {

"-1001234567890": {
"topics": {
"42": {

},
},
},

},
}
```
### Minimal Example (No Per-Binding ACP Overrides)
```jsonc
{
"agents": {
"list": [
{ "id": "main", "default": true, "runtime": { "type": "embedded" } },
{
"id": "codex",
"runtime": {
"type": "acp",
"acp": { "agent": "codex", "backend": "acpx", "mode": "persistent" },
},
},
{
"id": "claude",
"runtime": {
"type": "acp",
"acp": { "agent": "claude", "backend": "acpx", "mode": "persistent" },
},
},
],
},
"acp": { "enabled": true, "backend": "acpx" },
"bindings": [
{
"type": "route",
"agentId": "main",
"match": { "channel": "discord", "accountId": "default" },
},
{
"type": "route",
"agentId": "main",
"match": { "channel": "telegram", "accountId": "default" },
},
{
"type": "acp",
"agentId": "codex",
"match": {
"channel": "discord",
"accountId": "default",
"peer": { "kind": "channel", "id": "222222222222222222" },
},
},
{
"type": "acp",
"agentId": "claude",
"match": {
"channel": "discord",
"accountId": "default",
"peer": { "kind": "channel", "id": "333333333333333333" },
},
},
{
"type": "acp",
"agentId": "codex",
"match": {
"channel": "telegram",
"accountId": "default",
"peer": { "kind": "group", "id": "-1009876543210:topic:5" },
},
},
],
}
```
Notes:
- `bindings[].type` is explicit:
- `route`: normal agent routing.
- `acp`: persistent ACP harness binding for a matched conversation.
- For `type: "acp"`, `match.peer.id` is the canonical conversation key:
- Discord channel/thread: raw channel/thread ID.
- Telegram topic: `chatId:topic:topicId`.
- `bindings[].acp.backend` is optional. Backend fallback order:
1. `bindings[].acp.backend`
2. `agents.list[].runtime.acp.backend`
3. global `acp.backend`
- `mode`, `cwd`, and `label` follow the same override pattern (`binding override -> agent runtime default -> global/default behavior`).
- Keep existing `session.threadBindings.*` and `channels.discord.threadBindings.*` for temporary binding policies.
- Persistent entries declare desired state; runtime reconciles to actual ACP sessions/bindings.
- One active ACP binding per conversation node is the intended model.
- Backward compatibility: missing `type` is interpreted as `route` for legacy entries.
### Backend Selection
- ACP session initialization already uses configured backend selection during spawn (`acp.backend` today).
- This proposal extends spawn/reconcile logic to prefer typed ACP binding overrides:
- `bindings[].acp.backend` for conversation-local override.
- `agents.list[].runtime.acp.backend` for per-agent defaults.
- If no override exists, keep current behavior (`acp.backend` default).
## Architecture Fit in Current System
### Reuse existing components
- `SessionBindingService` already supports channel-agnostic conversation references.
- ACP spawn/bind flows already support binding through service APIs.
- Telegram already carries topic/thread context via `MessageThreadId` and `chatId`.
### New/extended components
- **Telegram binding adapter** (parallel to Discord adapter):
- register adapter per Telegram account,
- resolve/list/bind/unbind/touch by canonical conversation ID.
- **Typed binding resolver/index**:
- split `bindings[]` into `route` and `acp` views,
- keep `resolveAgentRoute` on `route` bindings only,
- resolve persistent ACP intent from `acp` bindings only.
- **Inbound binding resolution for Telegram**:
- resolve bound session before route finalization (Discord already does this).
- **Persistent binding reconciler**:
- on startup: load configured top-level `type: "acp"` bindings, ensure ACP sessions exist, ensure bindings exist.
- on config change: apply deltas safely.
- **Cutover model**:
- no channel-local ACP binding fallback is read,
- persistent ACP bindings are sourced only from top-level `bindings[].type="acp"` entries.
## Phased Delivery
### Phase 1: Typed binding schema foundation
- Extend config schema to support `bindings[].type` discriminator:
- `route`,
- `acp` with optional `acp` override object (`mode`, `backend`, `cwd`, `label`).
- Extend agent schema with runtime descriptor to mark ACP-native agents (`agents.list[].runtime.type`).
- Add parser/indexer split for route vs ACP bindings.
### Phase 2: Runtime resolution + Discord/Telegram parity
- Resolve persistent ACP bindings from top-level `type: "acp"` entries for:
- Discord channels/threads,
- Telegram forum topics (`chatId:topic:topicId` canonical IDs).
- Implement Telegram binding adapter and inbound bound-session override parity with Discord.
- Do not include Telegram direct/private topic variants in this phase.
### Phase 3: Command parity and resets
- Align `/acp`, `/new`, `/reset`, and `/focus` behavior in bound Telegram/Discord conversations.
- Ensure binding survives reset flows as configured.
### Phase 4: Hardening
- Better diagnostics (`/acp status`, startup reconciliation logs).
- Conflict handling and health checks.
## Guardrails and Policy
- Respect ACP enablement and sandbox restrictions exactly as today.
- Keep explicit account scoping (`accountId`) to avoid cross-account bleed.
- Fail closed on ambiguous routing.
- Keep mention/access policy behavior explicit per channel config.
## Testing Plan
- Unit:
- conversation ID normalization (especially Telegram topic IDs),
- reconciler create/update/delete paths,
- `/acp bind --persist` and unbind flows.
- Integration:
- inbound Telegram topic -> bound ACP session resolution,
- inbound Discord channel/thread -> persistent binding precedence.
- Regression:
- temporary bindings continue to work,
- unbound channels/topics keep current routing behavior.
## Open Questions
- Should `/acp spawn --thread auto` in Telegram topic default to `here`?
- Should persistent bindings always bypass mention-gating in bound conversations, or require explicit `requireMention=false`?
- Should `/focus` gain `--persist` as an alias for `/acp bind --persist`?
## Rollout
- Ship as opt-in per conversation (`bindings[].type="acp"` entry present).
- Start with Discord + Telegram only.
- Add docs with examples for:
- “one channel/topic per agent”
- “multiple channels/topics per same agent with different `cwd`
- “team naming patterns (`codex-1`, `claude-repo-x`)".

summary: "Proposal: long-term command authorization model for ACP-bound conversations"
read_when:
- Designing native command auth behavior in Telegram/Discord ACP-bound channels/topics
title: "ACP Bound Command Authorization (Proposal)"
---
# ACP Bound Command Authorization (Proposal)
Status: Proposed, **not implemented yet**.
This document describes a long-term authorization model for native commands in
ACP-bound conversations. It is an experiments proposal and does not replace
current production behavior.
For implemented behavior, read source and tests in:
- `src/telegram/bot-native-commands.ts`
- `src/discord/monitor/native-command.ts`
- `src/auto-reply/reply/commands-core.ts`
## Problem
Today we have command-specific checks (for example `/new` and `/reset`) that
need to work inside ACP-bound channels/topics even when allowlists are empty.
This solves immediate UX pain, but command-name-based exceptions do not scale.
## Long-term shape
Move command authorization from ad-hoc handler logic to command metadata plus a
shared policy evaluator.
### 1) Add auth policy metadata to command definitions
Each command definition should declare an auth policy. Example shape:
```ts
type CommandAuthPolicy =
| { mode: "owner_or_allowlist" } // default, current strict behavior
| { mode: "bound_acp_or_owner_or_allowlist" } // allow in explicitly bound ACP conversations
| { mode: "owner_only" };
```
`/new` and `/reset` would use `bound_acp_or_owner_or_allowlist`.
Most other commands would remain `owner_or_allowlist`.
### 2) Share one evaluator across channels
Introduce one helper that evaluates command auth using:
- command policy metadata
- sender authorization state
- resolved conversation binding state
Both Telegram and Discord native handlers should call the same helper to avoid
behavior drift.
### 3) Use binding-match as the bypass boundary
When policy allows bound ACP bypass, authorize only if a configured binding
match was resolved for the current conversation (not just because current
session key looks ACP-like).
This keeps the boundary explicit and minimizes accidental widening.
## Why this is better
- Scales to future commands without adding more command-name conditionals.
- Keeps behavior consistent across channels.
- Preserves current security model by requiring explicit binding match.
- Keeps allowlists optional hardening instead of a universal requirement.
## Rollout plan (future)
1. Add command auth policy field to command registry types and command data.
2. Implement shared evaluator and migrate Telegram + Discord native handlers.
3. Move `/new` and `/reset` to metadata-driven policy.
4. Add tests per policy mode and channel surface.
## Non-goals
- This proposal does not change ACP session lifecycle behavior.
- This proposal does not require allowlists for all ACP-bound commands.
- This proposal does not change existing route binding semantics.
## Note
This proposal is intentionally additive and does not delete or replace existing
experiments documents.
