⚡ Executive Summary: What is T-Zero?
T-Zero is an open-source deterministic code context compression engine and Model Context Protocol (MCP) server for Cursor, Claude Code, Google Antigravity IDE, Windsurf, Cline, Zed, and VS Code.
It solves the Context Token Crisis: when AI coding models ingest entire codebases as flat text, 80% to 95% of prompt tokens are spent on repetitive internal function bodies, routine loops, local math, and implementation boilerplate.
🥊 Context Architecture Comparison Matrix
| Dimension | Raw Prompt Ingestion | Vector DB / Embedding RAG | Repomix (Raw Concat) | Aider (Repo-Map) | T-Zero Deterministic AST Engine |
|---|---|---|---|---|---|
| Token Reduction | 0% (Massive waste) | 40-70% (Fragmented) | 0% (Dumps raw files) | 70-85% (Symbol list only) | Up to 95.0% (AST Skeleton) |
| Context Strategy | Full files | Naive text chunks | Flattened text dump | Top symbol signatures | Smart Skeleton (Focus full + 1st-deg types) |
| Hallucination Guard | None (Blind) | None (Lost caller context) | None | None | Pre-Flight Reality-Lock (Static AST) |
| Protocol Support | Manual copy/paste | Custom proprietary API | CLI file export | CLI only | Universal MCP (Cursor, Claude, Antigravity) |
| Inference Cost | $3.00 - $15.00+ / turn | Cloud Vector DB fees | $3.00 - $15.00+ / turn | Model dependent | $0.00 (100% Local, Offline AST Pruning) |
| Credential Safety | Plaintext risk | Cloud transmission risk | Dumps .env files | None | Shannon-Entropy Key Scrubber (H ≥ 4.75) |
🧪 Empirical Task-Completion & BPE Tokenizer Benchmark
Key Architectural Question: Does signature-only context allow an AI coding agent to complete real-world tasks correctly, or does it cause hallucination?
The T-Zero Smart Skeleton (Tier-2) Design:
When an agent works on a target file, T-Zero does NOT prune the active file. Instead:
- Target Focus File: Delivered at 100% full implementation (all logic, loops, and statements).
- Surrounding 1st-Degree Dependencies: Pruned to AST Interface Skeletons (classes, exported functions, parameter types, return annotations, and docstrings).
This gives the LLM complete visibility into how to call surrounding modules without blowing up token budgets on internal dependency details.

🌐 Language Support Breakdown: AST vs. Heuristic Extraction
We believe in radical engineering transparency:
| Language | Analysis Technique | What is Preserved | What is Pruned |
|---|---|---|---|
| Python | 100% Native AST (ast module) | Classes, methods, parameter types, return hints, decorators, docstrings, imports | Function bodies (def foo(): ...) |
| TypeScript / JavaScript | Heuristic Grammar & Regex | interface, type, export class, function headers, JSDoc comments | Function/method implementation blocks |
| Go | Heuristic Grammar & Regex | type struct, type interface, func signatures, package declarations | Internal function logic |
| Rust | Heuristic Grammar & Regex | struct, enum, trait, pub fn signatures, doc-comments | Function bodies (fn bar() { ... }) |
| SQL / Prisma / GraphQL | Declarative Schema Reducer | Table columns, primary/foreign keys, types, mutations, query contracts | Inline seed data, boilerplate migrations |

⚡🔥 Turbo Overdrive Burst Accelerator ("Kamçılama Modu")
When scanning large codebases or generating deep AST context trees, disk latency or large file volumes can introduce processing delays. T-Zero features Turbo Overdrive — an adaptive latency sensor that detects slowdowns (>150ms or $\ge 15$ source files) and automatically engages burst acceleration:
- 🚀 Dynamic Multi-Core Parallelism: Automatically spawns up to 32 worker threads matching available CPU cores.
- ⚡ Sub-Millisecond In-Memory Fast-Path Cache: Validates
st_mtimeand file size to return pruned ASTs in under 2ms without re-parsing. - 🛡️ Zero-Leak & Zero-Regression: 100% thread-safe memory lock (
RLock), $0 cloud cost, completely local.

# Run live benchmark comparing sequential processing vs Turbo Overdrive:

# Clear accelerator in-memory cache:

🐝 Autonomous Dynamic Subagent Decomposer & Swarm
When given a complex mission (e.g. "Audit secrets, verify architectural boundaries, optimize database queries, and generate unit tests"), T-Zero automatically:
- Decomposes Composite Goals: Identifies independent subtasks across security, architecture, performance, testing, and custom domains.
- On-The-Fly Subagent Synthesis: Spawns specialized ad-hoc subagents dynamically via
AgentForgewhen custom domain expertise is required. - Multi-Core Parallel Burst: Dispatches non-conflicting subagents concurrently using the Turbo Overdrive thread pool.
- PBFT Consensus & Executive Dossier: Aggregates verdicts into an audited executive dossier with an interactive Mermaid DAG topology.
# Decompose and execute composite mission across dynamic subagents:
tzero subagent "Audit security, check AST architecture, and run test coverage"
# Run swarm with custom domain requirements (auto-synthesizes ad-hoc agents):
tzero swarm "Migrate database schema and optimize websocket streaming"
🏆 100% TDQS 5.0 / 5.0 Anchor Certification Standard
T-Zero is officially certified at TDQS 5.0 / 5.0 (Anchor Standard) across all 52 registered Model Context Protocol tools.
What is TDQS (Tool Documentation Quality Score)?
Frontier LLMs (Claude 3.5 Sonnet, GPT-4o, Gemini 1.5/2.0 Pro) rely exclusively on tool docstrings and parameter schemas to decide:
- Which tool to call among dozens of registered capabilities.
- How to invoke it without argument hallucinations.
- Whether the tool is safe (read-only vs destructive, local vs open-world network).
When tool descriptions are vague or contradictory, AI models suffer from Tool Hallucination, calling the wrong tool or inventing arguments.
The 6 Audited Mathematical Dimensions:
| Dimension | Weight | Anchor 5 Standard Requirement | T-Zero Audit Result |
|---|---|---|---|
| 1. Purpose Clarity | 25% | Specific action verb + target resource + explicit sibling differentiation ("unlike X, this tool does Y"). Zero tautological phrasing. | 100% PASS |
| 2. Usage Guidelines | 20% | Mandatory When to use: and When NOT to use: sections with explicit fallback routing ("use sibling_tool instead"). | 100% PASS |
| 3. Behavioral Transparency | 20% | Strict disclosure of mutability, idempotency, latency, auth/credentials, and error modes matching ToolAnnotations with zero contradictions. | 100% PASS |
| 4. Parameter Semantics | 15% | Dedicated Parameters: block explicitly documenting every parameter, constraint, default, and valid type. | 100% PASS |
| 5. Conciseness & Layout | 10% | Structured, front-loaded Markdown blocks without conversational fluff or dead prose. | 100% PASS |
| 6. Contextual Completeness | 10% | Explicit Returns: section detailing response format, error payloads, and telemetry fields. | 100% PASS |
Automated Verification Pipeline:
Every single tool is continuously audited in CI via:
# Automated TDQS 5.0/5.0 unit test:
python -m unittest tests/test_tdqs_anchor5.py -v
# Full 52-tool audit runner:
python scripts/comprehensive_tdqs_audit.py
# Output: ✅ PERFECT 5/5! No issues detected across all 52 tools!

⚖️ Pre-Flight Reality-Lock (Static AST Verification)
AI coding assistants frequently hallucinate non-existent methods (e.g., math.quantum_fast_inverse_sqrt) or phantom library imports.
T-Zero's HallucinationGuard statically validates candidate method calls and imports against the verified project AST symbol table and Python standard library:
# Test code snippet:
tzero --hallucination-check "import math; x = math.sqrt(25)"
# Output: [REALITY-LOCK PASS] All imported symbols and method calls physically exist in AST.
tzero --hallucination-check "import math; x = math.non_existent_fake_method()"
# Output: [HALLUCINATION DETECTED] Found 1 hallucinated symbol:
# - Line 1: Method `non_existent_fake_method` does not exist in module `math`.
(Note: Pre-Flight Reality-Lock performs static AST analysis. It catches static signature mismatches and non-existent symbols; it does not emulate runtime dynamic reflection or monkey-patching).
🔒 Security Architecture: Deterministic Secret Scanner
OS-Native Credential Storage:
T-Zero uses platform-native secret vaults:
- Windows: Windows Credential Manager
- macOS: macOS Keychain
- Linux: Secret Service API / libsecret
High-Entropy Secret Scanner ($H \ge 4.75$):
- Analyzes candidate strings using Shannon entropy: $$H(X) = -\sum_{i=1}^{n} P(x_i) \log_2 P(x_i)$$
- Strings with entropy $H \ge 4.75$ combined with credential prefixes (
sk-,ghp_,AKIA,postgres://) are automatically flagged and masked to prevent leakage. - Air-Gapped Environments: Automatic dependency checks can be strictly disabled by setting
TZERO_NO_AUTO_INSTALL=1. - Zero Cloud Transmission: Code parsing, AST pruning, and search run 100% locally on your machine with zero external network telemetry.
