Zero syntax corruption guarantee for coding agents
Eliminate broken JSON, missing delimiters, and truncated tool schemas in production AI agent pipelines.
Tested across millions of automated tool invocations.
Eliminates wasted retry tokens caused by broken syntax.
Works seamlessly with Claude Code, Cursor, Windsurf, and LangChain.
The production engineering challenge
Coding agents and autonomous tools rely on deterministic JSON schemas and executable code. A single missing quotation mark or corrupted parameter causes entire tool execution chains to crash, creating expensive retry loops.
Technical architecture & mechanics
Pre-flight AST syntax verification
Validates code syntax and JSON schema parseability before and after payload transformation.
Automated fallback safeguard
Instantly rolls back to the original unmodified payload if any AST degradation or parse anomaly is detected.
Deterministic token boundaries
Prevents token cutting across multi-byte characters, escape sequences, or regex string literals.
Tool Call Schema Verification
Architecture comparison
| Evaluation metric | Curtly.dev gateway | Traditional / naive approach |
|---|---|---|
| Agent Tool Calling | Zero failures, 100% parseable tool JSON | Frequent parse errors requiring retry loops |
| Safety Fallback | Automated instant rollback to raw prompt | Throws runtime exception to client |
| Code Compilation | Passes AST linter and compiler checks | Syntax errors in truncated code blocks |
