Your AI coding agent is choking on context bloat. Every time Claude Code, Cursor, or Aider reads a 500-line source file just to inspect a single helper function, your token bill spikes and response latency collapses. Naive file reads force large language models to re-parse noise, hallucinate call sites, and lose context across repository boundaries.

Gortex fundamentally changes this operational pattern. Built in Go (requiring Go 1.26+ and CGO for tree-sitter C bindings), Gortex is a single static binary code-intelligence engine. Instead of dumping raw disk files into prompt context, Gortex parses 257 languages and grammars into an on-disk SQLite knowledge graph. It exposes this graph via a background daemon, CLI, HTTP server (`/v1/*` endpoints), and MCP Server (Model Context Protocol). 

By replacing brute-force file reads with graph-native depth queries, agents retrieve only the exact nodes, references, and cross-repo API contracts they need. The result is a 50x reduction in tokens per response.

## The Structural Core: Go, SQLite, and Tree-Sitter Resolution

Gortex operates as a zero-dependency, long-living daemon that supervises filesystem updates via `fsnotify`. The engine uses a MultiIndexer pipeline backed by an on-disk SQLite graph store. 

Because compiler-grade accuracy requires deterministic syntax processing, Gortex relies on CGO to link tree-sitter C bindings directly in-process. It processes 257 grammars across three distinct resolution tiers:
1. **Bespoke Tree-Sitter AST Analysis**: Deep syntax parsing with compiler-grade resolution for Go, Python, TypeScript/JavaScript, C, C++, C#, Java, Kotlin, Swift, Zig, Rust, Ruby, Elixir, PHP, OCaml, and Haskell.
2. **Regex Patterns**: Fallback structural indexing for unparsed text formats.
3. **Forest-Backed Signatures**: Dynamic resolution across notebook formats like Jupyter and Databricks.

Parsing accounts for 65% to 80% of total wall-time during initial indexing. Reference resolution and search index creation scale sub-linearly.

### Precomputed Depth-3 Reach Index

To compute blast radius during code edits, traditional tooling recursively scans directory trees, executing dozens of tool calls. Gortex eliminates this bottleneck by precomputing a depth-3 reach index directly within SQLite. Asking "what breaks if I touch this signature?" converts a dynamic tree traversal into an $O(\text{seeds} \times \text{reach})$ map lookup.

```go
// Conceptual reach representation inside Gortex graph engine
type ReachIndex struct {
    SeedNodeID string
    Depth      int
    Targets    []GraphNode
}
```

For workspace search, Gortex embeds a lightweight 3.8 MB GloVe-50d model directly into the binary. It couples this with store-native FTS5/BM25 and vector search using adaptive alpha fusion, delivering hybrid semantic search without external network calls or local model downloads.

## Cross-Repo HTTP Contracts and Routing Resolution

In distributed architectures, services communicate over HTTP endpoints, message queues, and RPC stubs. Single-repo tools fail at service boundaries. Gortex links multiple repositories inside a unified graph, establishing evidence-gated resolution across repo boundaries.

It automatically extracts, matches, and surface API contracts through the `contracts` MCP tool and the Gortex Web UI.

| Contract Type | Detection Method | Provider (Source Node) | Consumer (Target Node) |
| :--- | :--- | :--- | :--- |
| **HTTP Routes** | Framework annotations (gin, Express, FastAPI, Spring) | Route Handler | HTTP client calls (`fetch`, `http.Get`) |
| **gRPC** | Proto service definitions | Service RPC | Client stub calls |
| **GraphQL** | Schema type/field definitions | Schema | Query/mutation strings |
| **Message Topics** | Kafka, RabbitMQ, NATS, Redis pub/sub | Publish calls | Subscribe calls |
| **WebSocket** | Event emit/listen patterns | `emit()` | `on()` |
| **Env Vars** | `.env` files, system calls | `Setenv` / `.env` | `os.Getenv` / `process.env` |
| **OpenAPI** | Swagger / OpenAPI spec files | Spec paths | Linked HTTP routes |
| **Temporal Workflows** | Go / Java SDK annotations | Activity / workflow function | `ExecuteActivity` / `ExecuteChildWorkflow` |

Gortex normalizes HTTP routes across framework boundaries into canonical string identifiers:

```http
http::GET::/api/users/{id}
```

When a Go backend built with `gin` defines a route handler, and a TypeScript frontend invokes `fetch('/api/users/123')`, Gortex pairs provider and consumer nodes. If an engineer changes an HTTP route signature in the Go service, Gortex immediately flags the orphaned consumer in the TypeScript repository before integration testing.

## Real-World Scale and Performance Benchmarks

Engineered for massive enterprise monorepos and multi-repo workspaces, Gortex processes multi-gigabyte AST graphs while maintaining low memory footprints.

The following benchmarks were measured on an Apple Silicon laptop using standard CGO release builds:

| Repository | Total Files | Graph Nodes | Graph Edges | Index Time | Parsing Throughput | Peak Heap Memory |
| :--- | :--- | :--- | :--- | :--- | :--- | :--- |
| **torvalds/linux** | 70,333 | 1,690,174 | 6,239,570 | ~3 minutes | 300 files/s | 5.07 GB |
| **microsoft/vscode** | 10,762 | 204,501 | 808,902 | ~1 minute | 143 files/s | 580 MB |
| **zzet/gortex** (self) | 430 | 5,583 | 53,830 | 3.4 seconds | 127 files/s | 52 MB |

### Token Payload Efficiency: GCX1 vs JSON

To optimize transport efficiency when streaming graph snapshots to LLM agents, Gortex uses GCX1, a published, fully round-trippable wire format. Compared to standard JSON formats containing identical AST metadata, GCX1 reduces wire payload size by an additional 27%.

Combined with graph-native symbol lookups, agents avoid loading full files entirely.

```
Standard File Read Workflow:
  Agent ---> Requests user_service.go (850 lines) ---> Parses 18,000 tokens ---> Extracts 1 function signature

Gortex Graph Lookup Workflow:
  Agent ---> Query Engine (GCX1 wire format) --------> Returns 360 tokens ------> Exact node + callers
```

Developers can track cumulative context optimization using the built-in savings command:

```bash
gortex savings --verbose
```

Output:
```text

```

## Agent Adapter Integration and MCP Workflows

Gortex automatically detects and configures up to 20 AI coding agents on a developer's machine using `gortex init`. It supports Claude Code, Cursor, Windsurf, VS Code / Copilot, Continue.dev, Cline, OpenCode, Antigravity, Codex CLI, Gemini CLI, Zed, Aider, Kilo Code, OpenClaw, Hermes, Oh My Pi, Pi, and Kimi.

The system exposes over 100 MCP tools, 16 resources, and 3 prompt patterns. Key tools include:

- `contracts`: Inspects provider and consumer call sites across microservices.
- `preview_edit` and `simulate_chain`: Executes speculative edits against a live editor overlay (shadow graph) without altering disk state.
- `verify_change` and `check_guards`: Validates static call contracts before staging code changes.
- `pr_risk` and `get_pr_impact`: Analyzes merge order conflicts and compute graph blast radius during pull request reviews.

### Speculative Execution with Shadow Graphs

When an agent proposes an edit, modifying files on disk to test correctness consumes I/O and risks corrupting git state. Gortex introduces speculative execution through shadow graphs. 

```
+-------------------------------------------------------------+
|                     SPECULATIVE ENGINE                      |
|                                                             |
|  Unsaved Buffer  ---> Live Editor Overlay (Shadow Graph)    |
|                               |                             |
|                               v                             |
|  MCP Tools       <--- Read-Through Layer (Base + Overlay)   |
+-------------------------------------------------------------+
```

Unsaved buffers are streamed to the daemon as a transient shadow layer. Tools like `preview_edit` query through this shadow graph, allowing AI agents to test refactoring impact, check broken callers, and verify contract stability before touching a single line of real disk storage.

## Developer Quick Start Setup

Gortex installs as a single static binary with no runtime dependencies.

### Installation

For macOS and Linux environments:
```bash
curl -fsSL https://get.gortex.dev | sh
```

For Windows (PowerShell):
```powershell
irm https://get.gortex.dev/install.ps1 | iex
```

### Initializing a Project

1. Perform machine-level integration:
```bash
gortex install
```

2. Start the background daemon:
```bash
gortex daemon start --detach
```

3. Register target repositories with the multi-repo engine:
```bash
gortex track ~/projects/backend-service
gortex track ~/projects/frontend-app
```

4. Initialize agent hooks and MCP routing inside your active working directory:
```bash
cd ~/projects/backend-service && gortex init
```

Once initialized, all detected local AI tools communicate directly with the daemon through standard stdio or the HTTP `/v1/*` endpoint (including MCP 2026 Streamable HTTP). 

Telemetry is strictly opt-in and turned off by default. It respects environment flags like `DO_NOT_TRACK` and never transmits source code, file paths, or symbol identifiers.

```bash
# Check or toggle telemetry status
gortex telemetry status
```

By substituting raw text file ingestion with SQLite-backed AST graph indexing, Gortex solves the context degradation bottleneck inherent in AI-assisted software engineering.
