ui-tokenize — agentic threat model
ui-tokenize acts as an inline code-mutation guardrail on the write trust boundary of Claude Code. Its ability to silently modify file writes introduces high integrity risks if the token-reviewer agent or hook logic is bypassed or exploited.

MAESTRO 7-layer threat model
Per-layer threats for this agent. Layers tagged “not certain from listing” are general, caveated commentary where the public description didn’t pin that layer.
Not certain from the listing — The plugin relies on Claude Code's underlying foundation model (and its own token-reviewer agent) which is susceptible to prompt injection or adversarial bypasses to slip hardcoded literals or malicious code past the hook.
Not certain from the listing — The plugin maps literals to design tokens, implying a dictionary or vector store of design tokens, which could be poisoned or misconfigured, leading to incorrect code rewrites.
Sits directly on the write trust boundary as a PreToolUse hook in Claude Code. Vulnerabilities in the hook implementation or the orchestration framework could allow bypasses or unauthorized file mutations.
Not certain from the listing — Runs locally as a Claude Code plugin; security depends entirely on the host developer machine's sandboxing and file system permissions.
Features strict/advisory enforcement modes and surfaces advisories in PostToolUse, providing some observability, but silent rewrites in PreToolUse could mask unintended code modifications from the developer.
Acts as a compliance/security guardrail itself by blocking hardcoded UI literals, but lacks its own access control or signature verification to prevent tampering with its rules.
Employs a 'token-reviewer agent' for semantic checks, introducing multi-agent trust risks where the reviewer agent could be manipulated or fail to flag malicious rewrites.
