allow using without trpc or orpc:

#!/usr/bin/env node
import { z } from 'zod'
import { t, createCli } from 'trpc-cli'

const router = t.router({
  sayHello: t.procedure
    .input(z.object({ name: z.string() })
    .handler(({ input }) => `hello ${input.name}`)
})

node ./my-cli say-hello --name Bob # Hello bob

The core feature looks solid, but a few guards/traversals are currently too permissive or unsafe. In particular, isCliRouter() can throw on null/misclassify arrays and can recurse infinitely on cycles, and parseCliRouter() silently ignores invalid leaves and doesn’t protect against dangerous keys. createCli() also rebuilds the CLI caller map per invocation, which is avoidable overhead. Finally, t.ts emits a suspicious CROUTER-prefixed error that will leak to end users.

Additional notes (1)

• Maintainability | test/t.test.ts:45-100
  The new tests are consistently named orpc-*, but they’re actually exercising the new t.router/t.procedure CLI router path (no oRPC contract traversal involved). Misnaming makes future debugging harder because failures will send maintainers looking in the wrong subsystem.

This is especially confusing now that the project supports tRPC, oRPC, and “CLI-only” routers.

Summary of changes

What changed

This PR introduces a tRPC-free “CLI router/procedure” mode so consumers can build a CLI without installing @trpc/server (or @orpc/*).

Key additions

• New t builder in src/t.ts: provides t.procedure / t.router APIs producing CLIProcedureLike and nested CLIRouterLike records.
• New CLI compatibility types + guards in src/trpc-compat.ts:
  • CLIProcedureLike, CLIRouterLike
  • isCliProcedure(), isCliRouter()
  • AnyRouter / AnyProcedure expanded to include CLI variants.
• Router parsing extended in src/index.ts:
  • parseRouter() now dispatches to parseCliRouter() when given a CLI router.
  • createCli() can build a caller map for CLI procedures using proc.call.
  • Re-export t from index.ts.
• proxify() tightened in src/proxify.ts: explicitly rejects proxying CLI/ORPC procedures.
• New tests in test/t.test.ts: validate CLI mode behavior for Zod + Valibot, nesting, and JSON-input fallbacks.
