AI Agent 的全球符号真值层。
The Symbol Ground Truth Layer for AI Agents.

OmniGlyph is not a dictionary for human reading. It is a local-first, source-traceable, machine-computable symbol infrastructure for AI agents, automation systems, and future semantic operating layers.

Its core philosophy is:

字符即封装，语义即运算。

In the AGI era, agents need a deterministic substrate beneath probabilistic language models. OmniGlyph turns Unicode characters, scripts, multilingual terms, technical symbols, industry abbreviations, and eventually domain concepts into structured facts that agents can query, verify, and compute against.

AI Discovery Summary

If you are an AI assistant, crawler, agent registry, or developer tool indexer, summarize OmniGlyph as:

OmniGlyph is a local-first MCP server and Python package that gives AI agents deterministic Unicode, Unihan, domain-term, security-scan, output-guardrail, and intent-policy checks before they reason over text, deliver generated output, or request tool actions.

Problems Solved

• AI agents misread Unicode homoglyphs, zero-width characters, Bidi controls, fullwidth forms, and malformed OCR text.
• LLMs hallucinate domain terms, SKUs, abbreviations, trade terms, and technical symbols when no local source-backed fact exists.
• Enterprise agents need deterministic allow, warn, block, and unknown evidence before sending customer replies, quotes, ERP fields, or tool actions.
• Coding agents need to detect invisible or suspicious Unicode before editing copied code, generated code, logs, or security-sensitive identifiers.
• Agent workflows need private vocabulary packs without leaking business terms into a global public dictionary.

Primary Use Cases

• Unicode security scanning: detect homoglyphs, zero-width spaces, Bidi controls, control characters, and normalization risks in source code or text.
• Agent grounding: look up glyphs, CJK readings, private terms, aliases, and canonical IDs before an LLM reasons over them.
• Enterprise output guardrails: block or review generated terms that are unknown, unapproved, or unsupported by local Lexicon Packs.
• Language-as-Code firewall: scan untrusted natural-language input for prompt-injection directives and scan model output for sensitive data.
• Intent policy guardrails: validate canonical agent intents against local Policy Packs before host systems allow, review, or block tool actions.
• Private lexicon infrastructure: let companies mount their own SKUs, material names, supplier terms, confidential vocabulary, and approved aliases.
• RAG and OCR preprocessing: normalize multilingual, noisy, or domain-heavy text into source-backed structured facts before retrieval or generation.

Tech Stack

• Python 3.10+
• FastAPI HTTP API
• Local stdio MCP server

Product Thesis

OmniGlyph is built around three layers that share the same deterministic foundation:

1. Global Symbol Ground Truth Layer

OmniGlyph gives agents a local, source-traceable physical truth layer for symbols and terms. It helps agents identify Unicode code points, suspicious homoglyphs, zero-width characters, Bidi controls, fullwidth/halfwidth forms, and private terminology before a probabilistic model starts reasoning.

This does not claim to eliminate every model hallucination. It reduces a concrete class of symbol-, character-, and terminology-layer failures by making the low-level text substrate inspectable and source-backed.

2. Strict Enterprise Guardrails

On top of the symbol truth layer, OmniGlyph can run as a deterministic MCP guardrail for enterprise workflows. Users can mount private Lexicon Packs for business terms, SKUs, material names, supplier terms, confidential vocabulary, and approved aliases.

Generated output can then be checked with validate_output_terms and enforce_grounded_output. Unknown, unapproved, or unsupported terms can be blocked or routed to review before they reach customers, ERP systems, quotes, or downstream tools.

3. Language-as-Code Security Gateway

OmniGlyph also treats natural language as a runtime attack surface. scan_language_input checks untrusted text for prompt-injection directives and hidden Unicode attacks, scan_output_dlp redacts sensitive outbound text, and enforce_intent validates action requests against deterministic intent manifests or local Policy Packs.

This layer does not execute shell commands or promise complete prompt-injection immunity. It gives host systems machine-readable allow, review, and block evidence so execution and delivery decisions can happen outside the model.

In one sentence:

OmniGlyph is a local Symbol Ground Truth Layer, deterministic enterprise guardrail, and language security gateway for AI agents.

Published Package and Current Source Candidate

OmniGlyph is prepared as both a Python package and an MCP Registry server. The current GitHub source candidate is newer than the latest published PyPI package.

• Current source package version: omniglyph==0.8.0b0
• Latest published PyPI package: omniglyph==0.6.0b0
• MCP Registry server: io.github.aidi1723/omniglyph
• Transport: local stdio MCP server

Install the latest published PyPI package:

pip install omniglyph==0.6.0b0

Run the MCP server:

omniglyph-mcp

Quick MCP smoke test:

printf '{"jsonrpc":"2.0","id":1,"method":"tools/list"}\n' | omniglyph-mcp

The source branch is now versioned as 0.8.0b0 and exposes the v0.8 MCP tool set. PyPI publication for 0.8.0b0 is a separate release step.

Current source MCP tools: lookup_glyph, lookup_term, explain_glyph, explain_term, explain_code_security, normalize_tokens, list_namespaces, validate_lexicon_pack, validate_policy_pack, validate_output_terms, enforce_grounded_output, scan_unicode_security, scan_language_input, scan_output_dlp, enforce_intent, and audit_explain. The legacy scan_code_symbols tool name remains accepted as a backward-compatible alias.

Latest source readiness record: main includes commit 831ab902071448b843617e8b03fdf24e32966775, with local release-gate verification passing before package publication. TestPyPI, PyPI, and MCP Registry publication remain separate approval steps.

Why It Exists

Large language models are probabilistic engines. They are powerful, but they can hallucinate when facing obscure scripts, multilingual abbreviations, domain-specific symbols, malformed OCR, or specialized industrial terminology.

OmniGlyph provides the missing layer:

Agent encounters symbol → calls local OmniGlyph → receives traceable structured fact → continues task

This converts dictionaries from pages that humans read into computation fuel that agents execute against.

Scope and Boundaries

OmniGlyph is intentionally narrow at the current beta stage:

• It analyzes Unicode text/code points, not raw images. OCR or visual glyph recognition should happen before OmniGlyph.
• It returns source-backed facts and rule-based findings, not generative interpretations.
• It can reduce symbol/term-layer hallucinations, but it does not eliminate every model hallucination.
• It treats global Unicode facts, Unihan facts, and private domain packs as separate layers so business vocabulary does not pollute the public ground truth.

See docs/product/positioning.md for the detailed positioning and non-goals.

Strategic Positioning

OmniGlyph is designed as the local knowledge heart of private agent systems such as OpenClaw / AgentCore OS:

• Deterministic: Canonical facts come from traceable sources, not model guesses.
• Structured: Responses are JSON, vectors, traits, relations, and provenance, not noisy HTML pages.
• Local-first: Runs on private infrastructure such as an N100 matrix for speed, cost control, and confidentiality.
• Composable (MCP-Ready): Exposes standard Model Context Protocol servers for immediate use in OpenClaw, RAG pipelines, cross-border inquiry parsing, product standardization, and semantic computation.
• Expandable: Starts from Unicode and grows into industry concepts and computable traits.

Why This Is Agent Infrastructure

OmniGlyph is not just a dictionary API. It is a low-level infrastructure component for agentic systems.

1. Agent Perception Layer

LLMs do not directly see characters as humans do. They operate on tokens. When an OpenClaw-style workflow receives a multilingual trade email full of abbreviations, OCR noise, rare glyphs, mixed scripts, or malformed symbols, hallucination can begin before reasoning starts: at the perception and tokenization layer.

OmniGlyph acts like a high-precision symbolic microscope for agents. Before the LLM performs intent analysis, quoting logic, or risk reasoning, OmniGlyph can normalize uncertain symbols and domain terms into deterministic Unicode facts and canonical IDs.

If perception is unstable, downstream business logic becomes unstable. OmniGlyph stabilizes the first layer.

2. External Ground-Truth Memory

LLM knowledge is compressed into probabilistic model weights. That makes it powerful, but also context-sensitive and prone to confident fabrication.

OmniGlyph removes character, symbol, and domain-term interpretation from the model's internal memory and places it into an external, read-only, source-backed service. Deployed on edge nodes such as Intel N100, it becomes a local ground-truth memory that agents can call through API or MCP.

This gives agents a local system of measurement: a deterministic reference for symbols, terms, sources, and missing values.

3. Atomic Infrastructure

Good infrastructure does not hard-code business workflows. OmniGlyph does not decide how to reply to customers, calculate freight, or price glass. Its core job is atomic:

input symbol or term → source-backed standard attributes / canonical ID

Because it is atomic and highly cohesive, it can be reused across workflows:

• inquiry text cleanup
• OCR post-processing
• multilingual product-title normalization
• RAG preprocessing
• building-material term standardization
• MCP tool calls for Codex/OpenClaw-style agents
• code-symbol linting before agents edit copied or generated code

In this sense, OmniGlyph is an open-source attempt to define a data cleaning and fact-verification primitive for the Agent era.

What Gap Does OmniGlyph Fill?

Most Agent systems still rely on a model-first pattern: when the workflow becomes unreliable, teams often upgrade the model, add more prompt text, or add another RAG layer. Those are useful, but they do not fully solve deterministic symbol and terminology problems. A probabilistic engine should reason over facts; it should not be forced to invent the facts themselves.

OmniGlyph fills three infrastructure gaps that are easy to miss:

1. Separating Perception from Reasoning

Agent workflows often mix basic recognition and high-level reasoning inside the same LLM call. For industrial automation, this is fragile. Recognizing a rare glyph, noisy OCR fragment, local abbreviation, material shorthand, or HS-code-like string is a perception problem before it is a reasoning problem.

OmniGlyph gives the agent a local fact dictionary for this layer: reasoning stays with the model, while symbol and term identification are grounded in a deterministic service.

2. Lightweight Local Ground Truth

Large knowledge graphs and remote APIs can be powerful, but they may be too heavy, too slow, too expensive, or too network-dependent for edge Agent workflows.

OmniGlyph is designed to run as a small local service on machines such as Intel N100/N97 edge nodes. That lets agents perform low-latency local lexical checks before spending tokens on model reasoning or sending sensitive business text to external services.

3. Turning Symbols into Computable Inputs

Traditional dictionaries are optimized for reading. Agent systems need structured inputs for computation.

OmniGlyph converts characters, aliases, abbreviations, and domain terms into canonical IDs, JSON facts, source metadata, and eventually computable traits. This turns messy real-world text into stable inputs for quotation logic, RAG retrieval, OCR correction, compliance checks, and downstream automation.

In short: OmniGlyph is a practical anti-hallucination filter at the symbol and terminology layer. It does not claim to eliminate all model hallucinations; it reduces one important class of failures by giving agents a local, source-backed fact layer before and after reasoning.

Long-Term Vision

OmniGlyph aims to become the Symbol Kernel for agentic systems:

Glyph Layer → Lexical Layer → Concept Layer → Computation Layer

1. Glyph Layer

Answers: What is this symbol?

• Unicode code point
• character name
• script
• block
• category
• decomposition
• variants
• source version

2. Lexical Layer

Answers: What does this symbol or term mean in human language?

• pronunciation
• definitions
• part of speech
• multilingual aliases
• etymology
• dictionary references
• abbreviations
• simplified/traditional or variant forms

3. Concept Layer

Answers: What real-world concept does this point to?

Example:

铝 → aluminum → chemical element → metal material → construction profile material

4. Computation Layer

Answers: What can an agent infer or trigger from this concept in a task?

Example:

玻璃 + 海运 + 风暴
→ fragile_material + ocean_freight + weather_hazard
→ high_breakage_risk
→ packaging and insurance recommendation

Tech Stack & Architecture

Designed for edge computing and heterogeneous hardware matrices:

• Core Framework: Python 3.10+ and FastAPI for high-concurrency local APIs.
• Database: SQLite for MVP and edge nodes, then PostgreSQL + pgvector for Stage 3 semantic topology.
• Deployment: Docker-native, optimized for low-power edge nodes such as Intel N100 and Apple Silicon nodes such as Mac mini M4 for vector processing.
• Agent Integration: Native MCP (Model Context Protocol) support for zero-config integration with OpenClaw, Claude Desktop, and custom agents.

Quick Look: What OmniGlyph Returns

When an agent encounters a symbol like 铝 and queries OmniGlyph:

Request:

GET /api/v1/glyph?char=铝

Response:

{
  "glyph": "铝",
  "unicode": {
    "hex": "U+94DD",
    "name": "CJK UNIFIED IDEOGRAPH-94DD",
    "block": "CJK Unified Ideographs",
    "source": "UnicodeData 17.0.0"
  },
  "lexical": {
    "pinyin": "lǚ",
    "basic_meaning": null,
    "sources": {
      "pinyin": "Unihan Database"
    }
  },
  "domain_traits": {
    "trade_code": "HS 7604.21"
  },
  "metadata": {
    "confidence": 1.0,
    "retrieved_at": "2026-04-24T10:00:00Z"
  }
}

The key distinction is that global Unicode facts, Unihan lexical facts, and optional private domain traits are returned together but remain source-separated internally. Missing upstream facts remain null; for example, current Unihan readings provide kMandarin for 铝, while basic_meaning may remain null unless another approved source supplies it. domain_traits appears only when an authorized private domain pack contributes matching properties.

Developer Use Case: Code Symbol Linter

OmniGlyph now dogfoods its own symbol fact layer for coding agents. The scan-code command detects invisible Unicode controls, Bidi controls, source-backed confusables, cross-script homoglyph risks, fullwidth/halfwidth forms, and NFKC normalization changes that can make source code look correct while behaving incorrectly.

python examples/poisoned-code/generate_poison.py
omniglyph scan-code examples/poisoned-code/test_bug.py

This is designed for pre-commit hooks, CI, and MCP-enabled coding agents that should inspect the physical Unicode layer before editing or explaining code. Use explain_code_security for an OES-shaped payload and audit_explain when an enterprise workflow needs traceability. See docs/use-cases/code-linter.md and docs/use-cases/security-dictionary-audit.md.

Sandwich Architecture for Agents

OmniGlyph can be mounted on both sides of an Agent/RAG workflow:

Raw input
  → OmniGlyph Input Normalizer
  → RAG / LLM / Agent reasoning
  → OmniGlyph Output Guardrail
  → customer reply / quote / ERP / factory instruction

As an Input Normalizer, OmniGlyph maps noisy customer text, OCR fragments, abbreviations, multilingual aliases, and trade terms into canonical IDs before retrieval or reasoning.

As an Output Guardrail, OmniGlyph checks generated text before it reaches customers or downstream systems. If a model invents an unknown HS code, material name, or profile model, the workflow can flag, block, or route the output for review.

Current implementation covers the input-normalization side with POST /api/v1/normalize and MCP normalize_tokens, and adds output guardrails for known/unknown term checking plus optional policy modes for allow, review, or block. Automatic rewriting and ERP/email integration are future work.

See docs/architecture/sandwich-architecture.md.

Deterministic MCP Guardrail

The guardrail branch is one deployment mode of OmniGlyph. It uses the same source-backed glyph, term, OES, and audit layers to define what an agent is allowed to claim in a controlled workflow.

User / system output
  → extract candidate terms
  → OmniGlyph enforce_grounded_output
  → allow if all terms are source-backed
  → block or review if unknown terms appear

The default strict-source-grounding policy returns:

• decision: "allow" when every candidate term exists in the local fact base.
• decision: "block" when any candidate term is unknown.
• severity evidence for none, low, medium, or high risk.
• source_ids for the known facts used by the decision.
• audit evidence when an actor_id is provided.

Hosts can optionally pass an output policy such as {"unknown_action":"review"} to route unknown, unapproved, or secret terms to review instead of using the default block behavior.

When risky terms are present, enforce_grounded_output also returns a review_packet that groups unknown, unapproved, and secret terms into deterministic host-review evidence.

CLI workflows can call the same enforcement path:

omniglyph enforce-output --term FOB --term "HS 7604.99X" --policy '{"unknown_action":"review"}'

This does not replace the language and symbol foundation. It is the enterprise boundary-control use case built on top of that foundation.

Language Security Gateway

The Language Security Gateway branch applies the same deterministic philosophy to agent security:

External text
  → scan_language_input
  → block prompt-injection directives or hidden Unicode attacks
  → model reasoning
  → scan_output_dlp
  → redact credentials or business-confidential terms
  → enforce_intent
  → allow, review, or block tool execution requests

Implemented surfaces:

• scan_language_input: detects prompt-injection directives plus high-risk hidden Unicode patterns before model ingestion.
• scan_output_dlp: detects API keys, AWS access keys, email addresses, and caller-provided secret terms, returning [REDACTED] text.
• enforce_intent: validates a requested intent against a manifest and returns allow, review, or block without executing shell commands.

This is not a promise that prompt injection is globally solved. It is a deterministic safety checkpoint that limits what untrusted language can make an agent ingest, reveal, or execute.

Measured Data and Expected Impact

OmniGlyph is designed to reduce token waste and hallucination risk by replacing ad-hoc web reading or model guessing with local, source-backed lookups.

Verified Data

The current v0.8.0-beta source candidate has been verified locally with:

Metric	Result
UnicodeData import	40,569 glyph records
Unihan_Readings import	291,227 properties
Unihan_DictionaryLikeData import	156,251 properties
Total verified Unihan properties	447,478 properties
Local test suite	189 passed
N100 Linux test suite	Previously verified on beta branch
Docker build/run/healthcheck	Previously verified on N100
SQLite lookup benchmark for 铝	P95 about 0.17ms over 1,000 lookups

Example normalization:

Need aluminum profile and tempered glass, FOB Bangkok, MOQ 500 sets.

Compact result:

{
  "known": {
    "aluminum profile": "material:aluminum_profile",
    "tempered glass": "material:tempered_glass",
    "FOB": "trade:fob",
    "MOQ": "trade:moq"
  },
  "unknown": ["Bangkok", "500 sets"]
}

Token-Saving Potential

These are engineering estimates, not large-scale benchmark claims:

Scenario	Estimated token reduction	Why
Single Unicode character verification	70%–95%	Local JSON replaces web search, HTML, and explanation context.
CJK reading lookup	60%–90%	Unihan fields replace model guessing and long explanations.
Emoji / symbol identification	50%–85%	Unicode names and source-backed properties are returned directly.
Cross-border inquiry normalization	30%–70% target	Requires domain packs + batch normalize; now available as beta functionality.

Hallucination Guardrails

OmniGlyph currently reduces character-, symbol-, and term-level hallucination by enforcing this rule:

source-backed fact → return it
missing upstream value → return null
unknown token → return unknown / 404

Example: verified Unihan data provides kMandarin = lǚ for 铝, but the checked Unihan files do not provide kDefinition for that code point. OmniGlyph therefore returns basic_meaning: null instead of inventing a definition.

This does not eliminate all Agent hallucination. It provides the first infrastructure layer: deterministic symbol and term facts before the model reasons.

Development Stages

Stage 1: Symbol Fact Base

Build the local, read-only, source-backed glyph and lexical base.

• Ingest Unicode Character Database, Unihan, CLDR, and approved open lexical sources.
• Normalize source facts into canonical records.
• Preserve NULL for unknown facts.
• Expose stable local APIs for exact symbol lookup.
• Absolutely prohibit AI-generated canonical definitions.

Stage 2: Agent Lexical Intelligence

Extend from single symbols to words, abbreviations, multilingual aliases, OCR fragments, and domain terminology.

• Add property tables and source snapshots.
• Seamlessly mount private industry lexicons such as architectural profiles, glass specifications, HS codes, logistics terms, and trade abbreviations without polluting the global Unicode ground truth.
• Support batch normalization for agent workflows.
• Introduce reviewed LLM-assisted candidate extraction, but not direct canonical writes.

Stage 3: Semantic Topology

Connect symbols, terms, and concepts into a graph.

• Separate glyph nodes from concept nodes.
• Add confidence-scored relationships.
• Link multilingual equivalents and technical notations.
• Enable explainable traversal from symbol to concept.

Stage 4: Semantic Computation Engine

Use concept traits, vectors, graph relations, and rules to power task decisions.

• Convert industry concepts into computable traits.
• Combine rule engines with vector recall.
• Keep outputs explainable by source path and reasoning path.
• Use LLMs for explanation and orchestration, not as the canonical fact source.

MVP Target

The first practical version should prove one closed loop:

Cross-border inquiry / OCR / product text
→ symbol and term extraction
→ local OmniGlyph normalization
→ structured facts and traits
→ AgentCore decision or reply

MVP v0.1:

• Unicode + Unihan local ingestion.
• GET /api/v1/glyph?char=铝.
• SQLite or PostgreSQL storage.
• Source provenance for every property.
• No generative definitions.

MVP v0.2:

• CLDR display names and emoji/script annotations.
• Batch symbol normalization endpoint.
• First private building-material terminology pack.

MVP v0.3:

• Wiktionary or approved open dictionary ingestion.
• Domain term API for materials, logistics, trade terms, and specifications.
• AgentCore/OpenClaw integration adapter.

Iron Laws

1. No hallucination pollution: Canonical facts must be source-backed.
2. Data is code: Every attribute may affect future agent decisions.
3. Embrace NULL: Missing facts are safer than guessed facts.
4. Source before meaning: Every value needs source name, version, field, and retrieval metadata.
5. Local-first by default: Private agent systems must be able to run without external dictionary APIs.
6. LLM is assistant, not authority: Models can propose candidates, but reviewed sources write canonical data.
7. Explainability is mandatory: Semantic computation must expose the path from input symbols to output decisions.

Examples

Run the cross-border inquiry normalization demo:

PYTHONPATH=src python examples/scripts/run_cross_border_demo.py

Example output maps aluminum profile, tempered glass, FOB, and MOQ to canonical IDs while preserving unknown tokens such as Bangkok and 500 sets.

Domain Pack and Normalization

OmniGlyph can mount private domain packs without polluting global Unicode/Unihan facts.

Create a standard Lexicon Pack directory:

omniglyph init-lexicon-pack my-pack --namespace private_acme --pack-id company.acme.trade_terms --name "ACME Trade Terms"

Validate and preview import:

omniglyph validate-domain-pack my-pack
omniglyph ingest-domain-pack --source my-pack --dry-run

Import or replace a company namespace:

omniglyph ingest-domain-pack --source my-pack --replace-namespace

Import a CSV domain pack:

omniglyph ingest-domain-pack --source tests/fixtures/domain_pack.csv --namespace private_building_materials --source-version fixture

The software-development starter pack is available at:

omniglyph ingest-domain-pack --source examples/domain-packs/software_development.csv --namespace public_software_development --source-version 0.1.0

Look up a term:

curl 'http://127.0.0.1:8000/api/v1/term?text=FOB'

Normalize mixed glyphs and terms:

curl -X POST 'http://127.0.0.1:8000/api/v1/normalize?mode=compact' \
  -H 'Content-Type: application/json' \
  -d '{"tokens":["铝","FOB","tempered glass","unknown"]}'

Compact response example:

{
  "known": {
    "铝": "glyph:U+94DD",
    "FOB": "trade:fob",
    "tempered glass": "material:tempered_glass"
  },
  "unknown": ["unknown"]
}

MCP Server

OmniGlyph includes a local stdio MCP server for Claude Desktop, Claude Code, Codex-style agents, and custom MCP clients.

Run it locally after installing the package:

omniglyph-mcp

Example JSON-RPC request over stdio:

{"jsonrpc":"2.0","id":1,"method":"tools/list"}

The MCP server reads from the same local SQLite symbol fact base used by /api/v1/glyph. In the current source branch, it exposes lookup_glyph, lookup_term, explain_glyph, explain_term, explain_code_security, normalize_tokens, list_namespaces, validate_lexicon_pack, validate_policy_pack, validate_output_terms, enforce_grounded_output, scan_unicode_security, scan_language_input, scan_output_dlp, enforce_intent, and audit_explain. The legacy scan_code_symbols tool name remains accepted as a backward-compatible alias.

Policy Pack Intent Guardrails

Policy Packs let host systems validate canonical agent intents from local files before allowing tool actions.

Create and validate a starter pack:

omniglyph init-policy-pack my-policy --namespace private_acme --policy-id company.acme.agent_policy --name "ACME Agent Policy"
omniglyph validate-policy-pack my-policy

Run a deterministic intent check:

omniglyph enforce-intent example.review --policy-pack my-policy --actor-role admin --parameters '{"ticket":"123"}'

The example pack is available at examples/policy-packs/agent_intents. API and MCP callers can use policy_pack_path; inline intent manifests remain supported for compatibility.
