Compiling Natural Language to Typed DAGs: Eliminating AI Agent Prompt Injection and 60% Token Waste in Python

The Fragility of Stochastic Tool Calling

Modern agent frameworks delegate tool selection and parameter generation entirely to the LLM. In production, this introduces severe vulnerabilities:

• Prompt Injection: Attackers hide malicious instructions in input text or zero-width unicode characters.
• Type Mismatches: The LLM produces parameters with missing keys or invalid types, failing mid-pipeline.
• Token Waste: Multi-turn conversations burn hundreds of tokens debating which tool to call.

The Solution: agent-intent-compiler

By compiling prompts prior to execution, agent-intent-compiler provides:

1. Sub-Millisecond Sanitizer: Traverses AST syntax and analyzes Shannon entropy to halt hidden payloads.
2. Typed Slot Compiler: Maps intent into strict Pydantic v2 schemas.
3. Kahn's Algorithm DAG Stager: Prevents cycle loops and groups independent tasks for parallel execution.
4. Cryptographic SHA-256 Merkle Root: Issues a tamper-proof verification seal for every execution plan.

Quickstart Implementation

pip install agent-intent-compiler

from agent_intent_compiler import IntentCompiler, MCPAdapter

compiler = IntentCompiler()
plan = compiler.compile("Migrate the production PostgreSQL database schema and verify table constraints")

print("Plan ID:", plan.plan_id)
print("Intent:", plan.intent_type)
print("Stages:", plan.execution_order)
print("Merkle Receipt:", plan.merkle_root)

# Convert directly to Model Context Protocol (MCP) tool requests
mcp_requests = MCPAdapter.to_mcp_requests(plan)
print(f"Generated {len(mcp_requests)} MCP JSON-RPC calls.")
