Routing preflight
Shows the destination selected for each sanitized lead before rules are translated into an automation.

Lead Routing Simulator
/ Overview
A dependency-free Python CLI that previews prioritized lead assignments and overlapping routing rules without repeating lead attribute values.
Lead-routing rules can overlap or send unmatched records to an unexpected fallback. Reviewing them directly inside an automation builder makes priority behavior harder to isolate, while logging full lead attributes creates unnecessary data exposure.
/ Provided servicesClear thinking.
Clear thinking.
Practical delivery.
Overlap review
Keeps the winning rule and lower-priority matches visible so broad conditions can be reviewed.
Data-minimized output
Reports identifiers and routing outcomes without copying lead attributes into logs.
/ Solution
Lead Routing Simulator validates one bounded local JSON plan, evaluates equals, one-of and exists conditions, orders matches by descending priority with stable source-order ties, and sends unmatched leads to an explicit default team. It reports lead IDs, destination teams, selected routes and lower-priority overlaps without repeating attribute values. It does not connect to n8n or a CRM, mutate leads, balance capacity, judge fairness or prove production readiness.
/ Impact
Three declarative condition types
Deterministic priority ordering
Stable tie handling
Explicit default destination
Overlapping-route detection
Value-free reports
100 routes and 1,000 leads
Eleven standard-library tests
Python standard library
Argparse, JSON and pathlib provide a dependency-free offline command-line tool.
Declarative rule evaluation
A small condition engine handles equality, membership and presence with explicit priority semantics.
Unittest
Eleven tests cover operators, priorities, ties, fallbacks, overlaps, duplicate keys and value-free output.
