get_index_status	Get indexing status and statistics for a codebase
clear_index	Delete all indexed data for a codebase

Search Parameters

rerank — Result Reranking

Reorder search results based on git metadata signals.

For semantic_search / hybrid_search (analytics):

Preset	Use Case	Signals
relevance	Default semantic similarity	similarity only
techDebt	Find legacy problematic code	age + churn + bugFix + volatility
hotspots	Bug hunting	chunkChurn + chunkRelativeChurn + burstActivity + bugFix + volatility
codeReview	Review recent changes	recency + burstActivity + density + chunkChurn
onboarding	Entry points for new devs	documentation + stability
securityAudit	Old code in critical paths	age + pathRisk + bugFix + ownership + volatility
refactoring	Refactoring candidates	chunkChurn + relativeChurnNorm + chunkSize + volatility + bugFix + age
ownership	Knowledge transfer	ownership + knowledgeSilo (flags single-author code)
impactAnalysis	Dependency analysis	imports count

For search_code (practical development):

Preset	Use Case	Boost
relevance	Default semantic similarity	—
recent	Find recently modified code	low ageDays
stable	Find stable implementation examples	low commitCount

Custom weights:

{ "custom": { "similarity": 0.7, "recency": 0.3 } }

Available weight keys: similarity, recency, stability, churn, age, ownership, chunkSize, documentation, imports, bugFix, volatility, density, chunkChurn, relativeChurnNorm, burstActivity, pathRisk, knowledgeSilo, chunkRelativeChurn

metaOnly — Metadata Only Response

For semantic_search / hybrid_search only. Returns metadata without content:

{
  "score": 0.87,
  "relativePath": "src/auth/login.ts",
  "startLine": 45,
  "endLine": 89,
  "language": "typescript",
  "chunkType": "function",
  "name": "handleLogin",
  "imports": ["express", "jsonwebtoken", "./utils"],
  "git": { "ageDays": 5, "commitCount": 12, "dominantAuthor": "alice" }
}

imports contains file-level imports (inherited by all chunks from that file). Used by impactAnalysis reranking to boost files with many dependencies.

Use for file discovery, analytics, or reducing response size.
