**Title:** Implement tool call intercept with briefing injection
|
||
|
|
|
||
|
|
**Status:** done
|
||
|
|
|
||
|
|
**Dependencies:** 50 ✓, 51 ✓
|
||
|
|
|
||
|
|
**Priority:** high
|
||
|
|
|
||
|
|
**Description:** When a gated session calls a tool without first calling begin_session, intercept the call, extract keywords, match prompts, and inject the briefing alongside the real tool result.
|
||
|
|
|
||
|
|
**Details:**
|
||
|
|
|
||
|
|
1. Implement handleInterceptedCall in `/src/mcplocal/src/router.ts`:
|
||
|
|
```typescript
|
||
|
|
async handleInterceptedCall(
|
||
|
|
sessionId: string,
|
||
|
|
toolName: string,
|
||
|
|
args: any
|
||
|
|
): Promise<ToolResult> {
|
||
|
|
// 1. Extract keywords from tool call
|
||
|
|
const keywords = this.keywordExtractor.extractKeywords(toolName, args);
|
||
|
|
|
||
|
|
// 2. Match prompts using keywords
|
||
|
|
const { fullContent, indexOnly, remaining } =
|
||
|
|
await this.promptSelector.selectPrompts(keywords, this.promptIndex);
|
||
|
|
|
||
|
|
// 3. Execute the actual tool call
|
||
|
|
const actualResult = await this.routeToolCall(toolName, args);
|
||
|
|
|
||
|
|
// 4. Build briefing with intercept preamble
|
||
|
|
const briefing = this.buildBriefing(fullContent, indexOnly, remaining, 'intercept');
|
||
|
|
|
||
|
|
// 5. Ungate session
|
||
|
|
this.ungateSession(sessionId);
|
||
|
|
|
||
|
|
// 6. Send notifications/tools/list_changed
|
||
|
|
await this.sendToolsListChanged();
|
||
|
|
|
||
|
|
// 7. Return combined result
|
||
|
|
return {
|
||
|
|
content: [{
|
||
|
|
type: 'text',
|
||
|
|
text: `${briefing}\n\n---\n\n${actualResult.content[0].text}`
|
||
|
|
}]
|
||
|
|
};
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
2. Use gate-intercept-preamble system prompt for the briefing prefix
|
||
|
|
|
||
|
|
**Test Strategy:**
|
||
|
|
|
||
|
|
- Unit test: Tool call while gated triggers intercept
|
||
|
|
- Unit test: Keywords extracted from tool name and args
|
||
|
|
- Unit test: Prompts matched using extracted keywords
|
||
|
|
- Unit test: Actual tool still executes and returns result
|
||
|
|
- Unit test: Briefing prepended to tool result
|
||
|
|
- Unit test: Session ungated after intercept
|
||
|
|
- Unit test: notifications/tools/list_changed sent
|
||
|
|
- Unit test: Intercept preamble included in briefing
|
||
|
|
- Integration test: End-to-end intercept flow
