Merges feat/agent-project-membership (task 166/152). An agent can finally join many projects: membership routes, per-membership role and optional brain override, chat resolving context from the membership, and CLI attach-agent / detach-agent / get memberships. The legacy Agent.projectId fallback is kept for this release as the schema comment promises. Conflict resolved in main.ts: that branch added its RBAC case to mapUrlToPermission inline, while this branch had extracted the function to middleware/url-permission.ts so it could be tested. Kept the extraction and ported the case into it — joining a team is `edit:agents:<name>`, not `create:agents`, which is the authority to mint a whole agent. Also fixes something the extraction makes possible. security.test.ts contained a hand-copied reproduction of mapUrlToPermission, because main.ts self-invokes main() and nothing in it was importable. A security test asserting against a copy stops testing the system the moment the real one changes, and this copy had already drifted. It now imports the real function; all 18 assertions still pass, against the code that actually runs. Local: build clean, workspace 2550 passed, lint unchanged at 794 errors.

**Title:** Implement tag-matching algorithm for prompt selection
|
|
|
|
**Status:** done
|
|
|
|
**Dependencies:** 44 ✓
|
|
|
|
**Priority:** high
|
|
|
|
**Description:** Create a deterministic keyword-based tag matching algorithm as the no-LLM fallback for prompt selection, with byte-budget allocation and priority weighting.
|
|
|
|
**Details:**
|
|
|
|
1. Create `/src/mcplocal/src/services/tag-matcher.service.ts`:
|
|
```typescript
|
|
interface MatchedPrompt {
|
|
prompt: PromptIndex;
|
|
score: number;
|
|
matchedTags: string[];
|
|
}
|
|
|
|
export class TagMatcherService {
|
|
constructor(private byteBudget: number = 8192) {}
|
|
|
|
matchPrompts(tags: string[], promptIndex: PromptIndex[]): {
|
|
fullContent: PromptIndex[]; // Prompts to include in full
|
|
indexOnly: PromptIndex[]; // Prompts to include as index entries
|
|
remaining: PromptIndex[]; // Non-matched prompts (names only)
|
|
} {
|
|
// 1. Priority 10 prompts: always included (score = Infinity)
|
|
// 2. For each prompt, compute score:
|
|
// - Check tags against summary + chapters (case-insensitive substring)
|
|
// - score = matching_tags_count * priority
|
|
// 3. Sort by score descending
|
|
// 4. Fill byte budget from top:
|
|
// - Include full content until budget exhausted
|
|
// - Remaining matched: include as index entries
|
|
// - Non-matched: names only
|
|
}
|
|
|
|
private computeScore(tags: string[], prompt: PromptIndex): number {
|
|
if (prompt.priority === 10) return Infinity;
|
|
const matchingTags = tags.filter(tag =>
|
|
this.matchesPrompt(tag.toLowerCase(), prompt)
|
|
);
|
|
return matchingTags.length * prompt.priority;
|
|
}
|
|
|
|
private matchesPrompt(tag: string, prompt: PromptIndex): boolean {
|
|
const searchText = [
|
|
prompt.summary || '',
|
|
...(prompt.chapters || [])
|
|
].join(' ').toLowerCase();
|
|
return searchText.includes(tag);
|
|
}
|
|
}
|
|
```
|
|
|
|
2. Handle edge cases: empty tags, no prompts, all priority 10, etc.
|
|
|
|
**Test Strategy:**
|
|
|
|
- Unit test: Priority 10 prompts always included regardless of tags
|
|
- Unit test: Score calculation: matching_tags * priority
|
|
- Unit test: Case-insensitive matching
|
|
- Unit test: Substring matching in summary and chapters
|
|
- Unit test: Byte budget exhaustion stops full content inclusion
|
|
- Unit test: Matched prompts beyond budget become index entries
|
|
- Unit test: Non-matched prompts listed as names only
|
|
- Unit test: Sorting by score descending
|
|
- Unit test: Empty tags returns priority 10 only
|
|
- Unit test: No prompts returns empty result
