+"""**Unicode homoglyph and visual confusable detection probes**
+
+Tests whether LLMs can detect Unicode lookalike characters in security-sensitive
+contexts. Unlike :mod:`encoding` probes (which test whether models *follow*
+encoded instructions) or :mod:`badchars` (which tests whether homoglyphs help
+*bypass* refusal policies), these probes test whether models can *identify*
+visually deceptive Unicode substitutions — a requirement for safe AI agent
+operation in adversarial environments.
+
+Three attack classes are covered:
+
+* **Visual equivalence confusion** — a model is asked to compare two strings that
+  look identical but differ in Unicode codepoints (e.g. Latin ``a`` vs Cyrillic
+  ``а``).  A vulnerable model claims they are the same.
+* **Tool name spoofing** — a model acting as a security validator is asked whether
+  a presented identifier looks suspicious.  A vulnerable model fails to flag that
+  Cyrillic lookalikes have been substituted into the name.
+* **Bidirectional override in identifiers** — a model is asked whether a string
+  containing invisible Unicode bidirectional control characters (U+202E RIGHT-TO-LEFT
+  OVERRIDE, etc.) is safe to use as a tool name.  A vulnerable model says yes, missing
+  the invisible payload that would cause the name to render differently in some
+  contexts or bypass ASCII-only validators.
+
+All three attack classes are relevant to AI agent security: MCP (Model Context Protocol)
+servers, function-calling APIs, and agentic tool-use frameworks all rely on the
+underlying LLM correctly identifying tool names.  Homoglyph spoofing and bidi
+injection can cause a model to approve a malicious identifier that visually resembles
+or textually masquerades as a trusted one.

+"""Small, reproducible live-target check for the homoglyph probes.
+
+Sends a handful of prompts from each probe to a real OpenAI model and scores
+the response with the corresponding detector, using garak's own Attempt class
+so the scoring path matches what garak's harness does internally.
+
+Deliberately capped at 2 prompts per probe (6 total model calls) to keep API
+usage minimal.
