+# Dirigent — Feature List
+
+All implemented features across all versions.
+
+---
+
+## Core: Rule-Based No-Reply Gate
+- Deterministic logic in `before_model_resolve` hook decides whether to route to no-reply model
+- **human-list** mode: humanList senders bypass gate; others need end symbol to pass
+- **agent-list** mode: agentList senders need end symbol; others bypass
+- Non-Discord messages skip entirely
+- DM sessions (no metadata) always bypass
+- Per-channel policy overrides via JSON file (runtime-updateable)
+
+## Core: End-Symbol Enforcement
+- Injects prompt instruction: "Your response MUST end with 🔚"
+- Gateway keywords (NO_REPLY, HEARTBEAT_OK) exempt from end symbol
+- Group chats get additional rule: "If not relevant, reply NO_REPLY"
+- End symbols configurable per-channel via policy
+
+## Core: No-Reply API
+- OpenAI-compatible API (`/v1/chat/completions`, `/v1/responses`, `/v1/models`)
+- Always returns `NO_REPLY` — used as the override model target
+- Optional bearer auth (`AUTH_TOKEN`)
+- Auto-started/stopped with gateway lifecycle
+
+## Turn-Based Speaking (Multi-Bot)
+- Only the current speaker is allowed to respond; others forced to no-reply model
+- Turn order auto-populated from bot accounts seen in each channel
+- Turn advances on end-symbol (successful speech) or NO_REPLY
+- Successful speech resets NO_REPLY cycle counter
+- If all bots NO_REPLY in a cycle → channel goes **dormant**
+- Dormant reactivation: human message → first in order; bot message → next after sender
+- Turn timeout: auto-advance after 60s of inactivity
+- Manual control: `/dirigent turn-status`, `/dirigent turn-advance`, `/dirigent turn-reset`
+
+## Human @Mention Override *(v0.3.0)*
+- When a `humanList` user @mentions specific agents (`<@USER_ID>`):
+  - Extracts mentioned Discord user IDs from message content
+  - Maps userIds → accountIds via reverse bot token lookup
+  - Filters to agents in the current turn order
+  - Orders by their position in the current turn order
+  - Temporarily replaces speaking order with only those agents
+  - Cycle: a → b → c → (back to a) → restore original order, go dormant
+- Edge cases:
+  - All override agents NO_REPLY → restore + dormant
+  - `resetTurn` clears any active override
+  - Human message without mentions → restores override, normal flow
+  - Mentioned users not in turn order → ignored
+
+## Agent Identity Injection
+- Group chat prompts include: agent name, Discord accountId, Discord userId
+- userId resolved from bot token (base64 first segment)
+
+## Scheduling Identifier
+- Configurable identifier (default: `➡️`) used for moderator handoff
+- Handoff format: `<@TARGET_USER_ID>➡️` (non-semantic scheduling signal)
+- Agent prompt explains: identifier is meaningless — check chat history, decide whether to reply
+- If nothing to say → NO_REPLY
+
+## Moderator Bot Presence
+- Maintains Discord Gateway WebSocket connection for moderator bot
+- Shows "online" status with "Moderating" activity
+- Handles reconnect, resume, heartbeat, invalid session recovery
+- Singleton guard prevents duplicate connections
+- Sends handoff messages to trigger next speaker's turn
+
+## Individual Tools *(v0.3.0)*
+Nine standalone tools (split from former monolithic `dirigent_tools`):
+
+### Discord Control
+- **`dirigent_channel_create`** — Create private Discord channel with user/role permissions
+- **`dirigent_channel_update`** — Update permissions on existing private channel
+- **`dirigent_member_list`** — List guild members with pagination and field projection
+
+### Policy Management
+- **`dirigent_policy_get`** — Get all channel policies
+- **`dirigent_policy_set`** — Set/update a channel policy (listMode, humanList, agentList, endSymbols)
+- **`dirigent_policy_delete`** — Delete a channel policy
+
+### Turn Management
+- **`dirigent_turn_status`** — Show turn state (order, current speaker, dormant status, override info)
+- **`dirigent_turn_advance`** — Manually advance to next speaker
+- **`dirigent_turn_reset`** — Reset turn order (go dormant, clear overrides)
+
+## Slash Command: `/dirigent`
+- `status` — Show all channel policies
+- `turn-status` — Show turn state for current channel
+- `turn-advance` — Manually advance turn
+- `turn-reset` — Reset turn order
+
+## Project Rename (WhisperGate → Dirigent) *(v0.2.0)*
+- All plugin ids, tool names, config keys, file paths, docs updated
+- Legacy `whispergate` config key still supported as fallback
+
+## Installer Script
+- `scripts/install-dirigent-openclaw.mjs`
+- `--install` / `--uninstall` with delta-tracking
+- Auto-reinstall (uninstall + install) if already installed
+- Backup before changes, rollback on failure
+- Records stored in `~/.openclaw/dirigent-install-records/`
+
+## Discord Control API (Sidecar)
+- Private channel create/update with permission overwrites
+- Member list with pagination + field projection
+- Guardrails: action validation, id-list limits, response-size limit
+- Runs as optional companion service (`discord-control-api/`)

-1. 拆分 dirigent-tools：不再用一个主工具管理多个小工具。 ✅
-2. 人类@规则：当来自 humanList 的用户消息包含 <@USER_ID> 时，按被 @ 的 agent 顺序临时覆盖 speaking order 循环；回到首个 agent 后恢复原顺序。 ✅
