Extend CliPluginCommand with inputSchema/outputSchema/mcpHandler

Add three optional fields to the CliPluginCommand interface so plugin commands can declare structured input/output schemas and an MCP-friendly handler that bypasses argv parsing. Existing plugins keep working unchanged — the fields are purely additive.

    plan(v0.11.0): scaffold milestone and 17 work items

Acceptance Criteria

  • CliPluginCommand in @refrakt-md/types gains inputSchema?: JSONSchema7, outputSchema?: JSONSchema7, and mcpHandler?: (input: unknown) => Promise<unknown> fields
  • All three fields are optional; existing plugins compile and run without modification
  • JSDoc on each field documents its role: inputSchema for MCP tool input validation, outputSchema for structured output declaration, mcpHandler for direct structured invocation that bypasses argv parsing
  • Type-level test asserts that a plugin without these fields still satisfies the interface
  • JSONSchema7 type imported from @types/json-schema (already a likely transitive dep; add directly if not)

Approach

  1. Locate the current CliPluginCommand declaration. Today it lives inline in packages/cli/src/bin.ts; promote it to a shared type in @refrakt-md/types and re-export from there.

  2. Add the three optional fields with JSDoc.

  3. Update packages/cli/src/bin.ts to import the shared type instead of declaring its own.

  4. Update runes/plan/src/cli-plugin.ts to import the shared type for type-checking purposes (no runtime change in this work item).

Dependencies

  • None. Pure type additions.
