+# Design: Fix RuntimeStatusStar Spec Compliance
+
+## Problem
+
+The RuntimeStatusStar implementation does not match its specification:
+
+1. `get_protocol_status` should return protocol name along with connected state
+2. `get_stats` should return `total_messages` and `last_activity` not just `uptime_seconds`
+
+## Solution
+
+### 1. Update `get_protocol_status`
+
+**Current implementation:**
+```python
+return {
+    "lsp": {"connected": getattr(self._orchestrator.lsp, "connected", False)},
+    "mcp": {"connected": getattr(self._orchestrator.mcp, "connected", False)},
+    ...
+}
+```
+
+**Fixed implementation:**
+```python
+return {
+    "lsp": {
+        "connected": getattr(self._orchestrator.lsp, "connected", False),
+        "name": "lsp-client"
+    },
+    "mcp": {
+        "connected": getattr(self._orchestrator.mcp, "connected", False),
+        "name": "mcp-client"
+    },
+    ...
+}
+```
+
+### 2. Update `get_stats` and add message tracking
+
+**Orchestrator changes:**
+```python
+def __init__(self) -> None:
+    ...
+    self._message_count = 0
+    self._last_activity_timestamp: float | None = None
+
+def record_activity(self) -> None:
+    """Record a message activity for stats tracking."""
+    self._message_count += 1
+    self._last_activity_timestamp = time.time()
+```
+
+**RuntimeStatusStar changes:**
+```python
+def _get_stats(self) -> dict[str, Any]:
+    last_activity = None
+    if self._orchestrator and self._orchestrator._last_activity_timestamp:
+        last_activity = datetime.fromtimestamp(
+            self._orchestrator._last_activity_timestamp
+        ).isoformat()
+    
+    return {
+        "total_messages": getattr(self._orchestrator, "_message_count", 0),
+        "last_activity": last_activity,
+        "uptime_seconds": time.time() - self._start_time,
+    }
+```
+
+## Files to Modify
+
+1. `astrbot/_internal/runtime/orchestrator.py`:
+   - Add `_message_count: int = 0`
+   - Add `_last_activity_timestamp: float | None = None`
+   - Add `record_activity()` method
+
+2. `astrbot/_internal/stars/runtime_status_star.py`:
+   - Update `_get_protocol_status()` to include `name` field
+   - Update `_get_stats()` to return `total_messages` and `last_activity`
+
+3. `tests/unit/test_runtime_status_star.py`:
+   - Update `test_get_protocol_status` to verify `name` field
+   - Update `test_get_stats` to verify `total_messages` and `last_activity`

+## Why
+
+The RuntimeStatusStar was implemented based on a spec, but the implementation does not match the specification:
+
+1. `get_protocol_status` spec requires a `name` field per protocol, but implementation only returns `connected`
+2. `get_stats` spec requires `total_messages` and `last_activity` fields, but implementation only returns `uptime_seconds`
+
+This spec-implementation mismatch means external consumers cannot rely on the documented interface.
+
+## What Changes
+
+- Update `get_protocol_status` to include `name` field for each protocol client (lsp, mcp, acp, abp)
+- Update `get_stats` to return `total_messages` and `last_activity` as specified
+- Add message tracking infrastructure to the orchestrator to support `total_messages` and `last_activity`
+- Update tests to verify spec compliance
+
+## Capabilities
+
+### Modified Capabilities
+- `RuntimeStatusStar.get_protocol_status`: Now returns `{"lsp": {"connected": bool, "name": "lsp-client"}, ...}`
+- `RuntimeStatusStar.get_stats`: Now returns `{"total_messages": int, "last_activity": str, "uptime_seconds": float}`
+
+### New Infrastructure
+- Orchestrator message tracking: `_message_count` and `_last_activity_timestamp`
+
+## Impact
+
+- Modifies: `astrbot/_internal/stars/runtime_status_star.py` - add name fields and message stats
+- Modifies: `astrbot/_internal/runtime/orchestrator.py` - add message tracking counters
+- Modifies: `tests/unit/test_runtime_status_star.py` - update tests to verify spec compliance

+# RuntimeStatusStar Specification (Corrected)
+
+## Overview
+
+RuntimeStatusStar is an internal ABP (AstrBot Protocol) star plugin that exposes runtime state information via callable tools. It provides diagnostic capabilities for monitoring the AstrBot core runtime health.
+
+## Tool Interface
+
+### Tools Exposed
+
+All tools follow the ABP tool calling convention via `call_tool(tool_name, arguments)`.
+
+#### 1. get_runtime_status
+
+Returns the current runtime state.
+
+**Arguments:** None
+
+**Returns:**
+```json
+{
+  "running": true,
+  "uptime_seconds": 12345.67
+}
+```
+
+#### 2. get_protocol_status
+
+Returns the connection state of each protocol client.
+
+**Arguments:** None
+
+**Returns:**
+```json
+{
+  "lsp": {"connected": true, "name": "lsp-client"},
+  "mcp": {"connected": false, "name": "mcp-client"},
+  "acp": {"connected": true, "name": "acp-client"},
+  "abp": {"connected": true, "name": "abp-client"}
+}
+```
+
+#### 3. get_star_registry
+
+Returns the list of registered star names.
+
+**Arguments:** None
+
+**Returns:**
+```json
+{
+  "stars": ["runtime-status-star", "star-1", "star-2"]
+}
+```
+
+#### 4. get_stats
+
+Returns runtime statistics and metrics.
+
+**Arguments:** None
+
+**Returns:**
+```json
+{
+  "total_messages": 100,
+  "last_activity": "2024-01-01T00:00:00Z",
+  "uptime_seconds": 12345.67
+}
+```
+
+## Architecture
+
+### Component Hierarchy
+
+```
+AstrbotOrchestrator
+  └── RuntimeStatusStar (auto-registered)
+        └── Tools: get_runtime_status, get_protocol_status, get_star_registry, get_stats
+```
+
+### Message Tracking
+
+The orchestrator tracks:
+- `_message_count`: Total number of messages processed
+- `_last_activity_timestamp`: ISO timestamp of last activity
+
+### Auto-Registration
+
+RuntimeStatusStar is instantiated and registered in `AstrbotOrchestrator.__init__()`:
+
+```python
+from astrbot._internal.stars.runtime_status_star import RuntimeStatusStar
+
+class AstrbotOrchestrator:
+    def __init__(self):
+        self._stars: dict[str, Star] = {}
+        self._message_count = 0
+        self._last_activity_timestamp: float | None = None
+        # Auto-register RuntimeStatusStar
+        self._runtime_status_star = RuntimeStatusStar()
+        self._runtime_status_star.set_orchestrator(self)
+        self._stars["runtime-status-star"] = self._runtime_status_star
+```
+
+### Orchestrator Reference
+
+RuntimeStatusStar holds a reference to the orchestrator to query state:
+
+```python
+class RuntimeStatusStar:
+    def __init__(self):
+        self._orchestrator = None
+        
+    def set_orchestrator(self, orchestrator):
+        self._orchestrator = orchestrator
+```
+
+## Implementation Notes
+
+1. **Thread Safety:** The orchestrator may be accessed from multiple contexts. All state queries should be read-only.
+
+2. **Latency:** Tool calls should return immediately without blocking. No polling or long-running operations.
+
+3. **Error Handling:** If any status query fails, return an error message rather than raising an exception.
+
+4. **Future Extensibility:** Additional stats can be added by extending the `get_stats` tool response structure.

+# Runtime Status Star Specification (Spec Compliance Fix)
+
+## MODIFIED Requirements
+
+### Requirement: RuntimeStatusStar provides diagnostic tools
+
+The RuntimeStatusStar SHALL provide callable tools that expose core runtime internal state for diagnostic purposes.
+
+#### Scenario: Get runtime status
+- **WHEN** ABP client calls `get_runtime_status` tool
+- **THEN** returns `{"running": bool, "uptime_seconds": float}`
+
+#### Scenario: Get protocol status
+- **WHEN** ABP client calls `get_protocol_status` tool
+- **THEN** returns status of each protocol client (lsp, mcp, acp, abp)
+- **AND** each protocol includes `connected: bool` AND `name: string` fields
+- **EXAMPLE**: `{"lsp": {"connected": true, "name": "lsp-client"}, ...}`
+
+#### Scenario: Get star registry
+- **WHEN** ABP client calls `get_star_registry` tool
+- **THEN** returns list of registered star names
+
+#### Scenario: Get stats
+- **WHEN** ABP client calls `get_stats` tool
+- **THEN** returns `{"total_messages": int, "last_activity": string, "uptime_seconds": float}`
+- **AND** `last_activity` is ISO8601 formatted timestamp string
+
+### Requirement: Auto-registration with orchestrator
+
+The RuntimeStatusStar SHALL be automatically registered with the orchestrator on initialization.
+
+#### Scenario: Orchestrator initialization
+- **WHEN** AstrbotOrchestrator is created
+- **THEN** RuntimeStatusStar instance is created and registered with name "runtime-status-star"
+
+### Requirement: Orchestrator message tracking
+
+The orchestrator SHALL track message counts and last activity timestamp for stats reporting.
+
+#### Scenario: Message tracking
+- **WHEN** orchestrator processes a message
+- **THEN** `_message_count` is incremented
+- **AND** `_last_activity_timestamp` is updated to current time
+
+#### Scenario: Stats retrieval
+- **WHEN** RuntimeStatusStar.get_stats is called
+- **THEN** returns `total_messages` from orchestrator's `_message_count`
+- **AND** returns `last_activity` as ISO8601 string from `_last_activity_timestamp`
+
+### Requirement: Error handling
+
+The RuntimeStatusStar tools SHALL handle errors gracefully without exposing internal exceptions.
+
+#### Scenario: Orchestrator unavailable
+- **WHEN** orchestrator reference is None
+- **THEN** returns appropriate error message instead of raising exception
