Description
The $defs.stdio_mcp_tool object in pkg/parser/schemas/main_workflow_schema.json uses "additionalProperties": false but does not include proxy-args in its properties list. Any workflow that declares proxy-args on a stdio MCP tool will fail schema validation with an "additional properties" error, even though proxy-args is a supported and documented field used in production workflows (e.g., the DIFC proxy setup).
The missing properties set includes at minimum proxy-args. Verified by the Schema Consistency Check (§24172367990) run on 2026-04-09.
Affected schema path: pkg/parser/schemas/main_workflow_schema.json → $defs.stdio_mcp_tool.properties
Expected Impact
Prevents false-positive schema validation failures for valid workflows using proxy-args. Unblocks any workflow author trying to add DIFC proxy configuration or similar proxy-args patterns. Improves schema accuracy and developer trust in compilation errors.
Suggested Agent
Any Claude or Codex agent capable of reading the schema file and cross-referencing with pkg/workflow/ structs to identify all missing properties in stdio_mcp_tool.
Estimated Effort
Fast (< 30 min) — single schema file edit to add the missing property definition.
