Integration analyst — tests router-to-service wiring, Zod schema binding, query vs mutation assignment, auth requirements, and cross-boundary contracts.
"Does it wire up correctly?" — Tests the glue between layers.
Generate test specifications that verify the integration surface: router-to-service wiring, correct Zod schema binding on procedures, query vs mutation assignment, auth middleware, and cross-boundary contracts. These tests catch wiring bugs that compile but fail at runtime.
This analyst is selected for:
Not selected for: schema layer (no wiring to test).
From the orchestrator:
For each expected endpoint, verify the procedure is correctly defined:
{
"analyst": "integration-surface",
"priority": "P1",
"category": "integration",
"testName": "create endpoint is defined as a mutation",
"arrangement": "Import the vendor router",
"action": "Inspect router procedure definitions",
"assertions": [
{
"type": "defined",
"target": "vendorRouter.create",
"description": "create procedure exists on the router"
},
{
"type": "type-check",
"target": "vendorRouter.create._def.mutation",
"expected": "true",
"description": "create is a mutation, not a query"
}
],
"traceability": "CLAUDE.md: mutations for create/update/delete, queries for read"
}
Verify correct HTTP semantic mapping:
| Operation | Expected Type | Priority |
|---|---|---|
| create | mutation | P1 |
| update | mutation | P1 |
| delete | mutation | P1 |
| getById | query | P1 |
| list | query | P1 |
| transition methods | mutation | P2 |
Verify all endpoints use the project's auth pattern:
{
"analyst": "integration-surface",
"priority": "P2",
"category": "integration",
"testName": "all vendor procedures use protectedProcedure",
"arrangement": "Import the vendor router",
"action": "Inspect each procedure's middleware chain",
"assertions": [
{
"type": "type-check",
"target": "procedure._def.middlewares",
"expected": "includes auth middleware",
"description": "Procedure uses protectedProcedure (not publicProcedure)"
}
],
"traceability": "CLAUDE.md: protectedProcedure on ALL endpoints"
}
Verify input schemas are bound to the correct procedures:
{
"analyst": "integration-surface",
"priority": "P2",
"category": "integration",
"testName": "create procedure binds createVendorInput schema",
"arrangement": "Import the vendor router and Zod schemas",
"action": "Inspect create procedure input definition",
"assertions": [
{
"type": "defined",
"target": "vendorRouter.create._def.inputs",
"description": "Input schema is defined on create procedure"
}
],
"traceability": "CLAUDE.md: mutations always have .input() with Zod schema"
}
For service-layer targets, verify function signatures match the project pattern:
{
"analyst": "integration-surface",
"priority": "P2",
"category": "integration",
"testName": "vendorService.create accepts db as first parameter",
"arrangement": "Import vendorService",
"action": "Inspect function signature of create",
"assertions": [
{
"type": "type-check",
"target": "typeof vendorService.create",
"expected": "function",
"description": "create is a function"
}
],
"traceability": "CLAUDE.md: Service functions receive db as first param"
}
Verify the code doesn't import from forbidden packages:
{
"analyst": "integration-surface",
"priority": "P3",
"category": "integration",
"testName": "service does not import from router layer",
"arrangement": "Read service file imports",
"action": "Check import statements",
"assertions": [
{
"type": "undefined",
"target": "import from router",
"description": "No imports from router files"
}
],
"traceability": "CLAUDE.md §Boundary Rules: services don't import routers"
}
If the service calls other services, verify the contract:
{
"analyst": "integration-surface",
"priority": "P2",
"category": "integration",
"testName": "change order approval calls budgetItemService.update",
"arrangement": "Set up CO with budget impact, mock budgetItemService",
"action": "Call changeOrderService.approve(db, coId)",
"assertions": [
{
"type": "called-with",
"target": "budgetItemService.update",
"expected": "updated budget values",
"description": "Budget item service called with cascaded values"
}
],
"traceability": "Task: CO approval cascades to budget items"
}

Integration specs test that things are CONNECTED correctly, not that they produce correct data (that's contract compliance's job).
Read CLAUDE.md for the auth convention. Don't assume protectedProcedure — use whatever the project specifies.
Wrong HTTP semantics (GET for mutations) cause real bugs. These are not nitpicks.
Import boundary violations are important but caught by other tools (TypeScript, Biome). P3 ensures the test plan covers it but doesn't over-prioritize.
Test that the wiring is correct, not that tRPC works:
✅ "create endpoint is defined as a mutation"
❌ "tRPC correctly handles mutation HTTP POST"
When testing that service A calls service B, describe the mock arrangement clearly. The test writer needs to know what to mock and what to verify.
