The Problem with Vector Databases

Traditional RAG systems use vector databases (Pinecone, Weaviate, Chroma) that rely on:

β€’ Approximate similarity search (ANN algorithms) β€’ Single-dimensional embeddings (cosine similarity only) β€’ Heuristic selection (no optimization guarantees) β€’ Cloud dependencies (latency, privacy, cost)

ContextLite's Solution

Instead of approximations, ContextLite uses:

β€’ Mathematical optimization via SMT solvers β€’ 7-dimensional feature scoring (not just similarity) β€’ Provably optimal selection (within defined constraints) β€’ 100% local operation (embedded SQLite + Z3)

Key Benefits

β€’ 100x faster than vector databases (0.3ms vs 30-50ms) β€’ Mathematically optimal context selection β€’ Zero cloud dependencies (pure Go binary) β€’ 100% privacy (data never leaves your machine) β€’ Adaptive learning (workspace-specific weight optimization)

SMT Optimization Theory

What is SMT?

Satisfiability Modulo Theories (SMT) is a mathematical framework for solving constraint satisfaction problems with provable optimality guarantees. SMT solvers like Z3, CVC4, and Yices are used in:

β€’ Formal verification β€’ AI planning β€’ Theorem proving β€’ Resource allocation

ContextLite's SMT Formulation

Context selection is modeled as a multi-objective optimization problem:

; Variables: binary selection indicators
(declare-fun select_doc_i () Bool)

; Objective: maximize weighted utility sum
(maximize (+ (* alpha_1 relevance_1 select_doc_1)
             (* alpha_2 relevance_2 select_doc_2)
             (* alpha_N relevance_N select_doc_N)))

; Constraints
(assert (<= (+ (* tokens_1 select_doc_1)
               (* tokens_2 select_doc_2)
               (* tokens_N select_doc_N)) max_tokens))

(assert (<= (+ select_doc_1 select_doc_2 ... select_doc_N) max_documents))

; Diversity constraints (pairwise similarity penalties)
(assert (=> (and select_doc_i select_doc_j) 
            (<= similarity_ij diversity_threshold)))

Three Optimization Strategies

1. Weighted-Sum Scalarization (Default)

maximize: Ξ£(Ξ±α΅’ Γ— FeatureScore(docα΅’))
subject to: token_budget, max_documents, diversity_constraints

2. Lexicographic Optimization

Strict priority ordering:

  1. Relevance (primary)
  2. Recency (secondary)
  3. Authority (tertiary)
  4. etc.

3. Ξ΅-Constraint Method

Optimize primary objective with secondary objectives as constraints:

maximize: relevance_score
subject to: recency_score β‰₯ Ρ₁, authority_score β‰₯ Ξ΅β‚‚, ...

7-Dimensional Feature System

ContextLite evaluates documents across 7 independent dimensions. Each feature is set-independent to ensure mathematical correctness in SMT optimization.

1. Relevance (Query Matching)

Purpose: How well does the document match the user's query?

Formula: BM25-based relevance scoring

Relevance = Ξ£(term ∈ query) IDF(term) Γ— TF_norm(term, doc)

Where:
- IDF(term) = log((N - df + 0.5) / (df + 0.5))
- TF_norm = tf Γ— (k1 + 1) / (tf + k1 Γ— (1 - b + b Γ— |doc| / avg_doc_len))
- k1 = 1.5, b = 0.75 (BM25 parameters)

Range: [0, ∞) (typically 0-20)

Properties: β€’ Text similarity (TF-IDF, BM25) β€’ Semantic similarity (optional embedding integration) β€’ Query term coverage

2. Recency (Temporal Relevance)

Purpose: Favor recently modified documents (fresh code, current documentation).

Formula: Exponential decay with 7-day half-life

Recency = exp(-ln(2) Γ— days_since_modification / 7.0)

Range: [0, 1]

Properties: β€’ 50% score after 7 days β€’ 25% score after 14 days β€’ Encourages current information

3. Entanglement (Cross-Document Concept Density)

Purpose: Measure internal semantic coherence of the document.

Formula: Point-wise Mutual Information (PMI) over term pairs

Entanglement = (1/|T|) Γ— Ξ£(i,j ∈ TΓ—T, iβ‰ j) PMI(i,j)

Where:
- PMI(i,j) = log(P(i,j) / (P(i) Γ— P(j)))
- T = top 20% most frequent terms in document

Range: [-∞, ∞] (typically -2 to +2)

Properties: β€’ Higher scores = more coherent, focused documents β€’ Lower scores = scattered, unfocused content

4. Prior Knowledge (Historical Usage Patterns)

Purpose: Learn from user selection patterns over time.

Formula: Path frequency with file type bias

Prior = log(1 + workspace_selection_count[doc.path]) Γ— extension_bias[doc.ext]

Where extension_bias:
- .go, .py, .js, .ts: 1.2 (source code priority)
- .md, .txt: 1.0 (documentation baseline)
- .json, .yaml: 0.8 (config files)
- .test.*: 0.6 (test files)

Range: [0, ∞) (typically 0-5)

Properties: β€’ Adaptive learning from user behavior β€’ File type preferences β€’ Workspace-specific patterns

5. Authority (Document Importance)

Purpose: Identify authoritative, important documents in the codebase.

Formula: Combination of size, centrality, and update frequency

Authority = size_score Γ— centrality_score Γ— commit_frequency_score

Where:
- size_score = log(1 + file_size_bytes / 1000)
- centrality_score = import_count + reference_count
- commit_frequency = log(1 + commits_last_30_days)

Range: [0, ∞) (typically 0-10)

Properties: β€’ Main source files score higher β€’ README, documentation gets authority boost β€’ Test files score lower

6. Specificity (Information Density)

Purpose: Favor documents with high information density relevant to the query.

Formula: Query-document topic alignment

Specificity = query_term_coverage Γ— unique_information_ratio

Where:
- query_term_coverage = |query_terms ∩ doc_terms| / |query_terms|
- unique_information_ratio = unique_concepts / total_concepts

Range: [0, 1]

Properties: β€’ Dense, informative content scores higher β€’ Verbose, redundant content scores lower β€’ Query-specific relevance

7. Uncertainty (Confidence Quantification)

Purpose: Measure confidence in the relevance assessment (subtracted from total score).

Formula: Coefficient of variation across multiple estimators

Uncertainty = std_dev(estimators) / mean(estimators)

Where estimators = [BM25_score, TF_IDF_score, cosine_similarity]

Range: [0, ∞) (typically 0-2)

Properties: β€’ High uncertainty = less confident relevance β€’ Low uncertainty = consistent scoring across methods β€’ Subtracted from total utility

πŸ†• Integration Patterns

VS Code Extension Integration

// Extension communicates via HTTP API
const contextAPI = new ContextLiteAPI('http://localhost:8080');

async function getContext(query: string): Promise<ContextResult> {
    const response = await contextAPI.getContext(query);
    return response.data;
}

CLI Integration

# Direct CLI usage
contextlite "implement user authentication"

# With specific parameters
contextlite --max-tokens 4000 --strategy lexicographic "fix database connection"

# Pipeline integration
cat query.txt | contextlite --format json > context.json

API Integration

import requests

def get_optimal_context(query: str) -> dict:
    response = requests.get(
        'http://localhost:8080/context',
        params={'query': query, 'max_tokens': 4000}
    )
    return response.json()
