--context-variables can only send Text, so a boolean-gated route
(available when @variables.x == True) never opens: the runtime compares
the string "True" against boolean True. Add --context-variables-json,
which takes a JSON array of typed variables ({ name, type, value })
matching the preview API's Variable schema, so Boolean/Number/Object/
List/Json values reach the wire with the correct type.
The JSON flag has no comma delimiter, so List/Object values (and any
comma-bearing value) are safe, unlike --context-variables. Both flags can
be combined; on a duplicate name the JSON entry wins. Each entry is
validated at parse time: name required, type in the enum, and value shape
checked against type.
Requires @salesforce/agents with the typed ContextVariable union.

What
Adds a new
--context-variables-jsonflag tosf agent previewandsf agent preview startso callers can send typed context variables (Boolean, Number, Object, List, Json) to the preview API, not justText.Why
--context-variables(the existingName=Valueflag) hard-codes every value as typeText. A boolean-gated route (for exampleavailable when @variables.probeGate == True) never opens, because the runtime compares the string"True"against the booleanTrue. See W-24014400.The new flag matches the preview API's own
Variableschema (a discriminated union keyed ontype), so a value is sent with the correct JSON type on the wire.How
contextVariablesJsonFlaginsrc/flags.ts, plusparseContextVariablesJson(validates JSON shape and that eachvaluematches its declaredtype) andmergeContextVariables(merges the text-form and JSON-form variables; on a duplicate name the JSON entry wins, keeping the text entry's position).agent:previewandagent:preview:startaccept both flags together.delimiteron the JSON flag, so commas inside a List/Object/JSON value are safe (unlike--context-variables, which splits on,).Notes
ContextVariablediscriminated union in@salesforce/agents(PR Feat/eval state injection @W-21514105@ #356). This branch currently builds against a localyarn linkof that SDK; once Feat/eval state injection @W-21514105@ #356 releases, bump the@salesforce/agentsversion here to drop the link.Tests
