Browser-local submitted JSON

Provider request envelope production kit

Compose a complete OpenAI, Anthropic, or Gemini request packet from canonical messages, tools, and strict output constraints. Examples use placeholders only and remain ready-to-review but inert: no credential is accepted and no provider is called.

Explicit-submit workbench

Run submitted JSON locally

Parsing and transformation happen in this browser. Nothing runs when a sample loads, and no input is fetched, uploaded, stored, or retained.

Submitted JSONUse strict JSON matching the published tool schema.

Deterministic resultCopy and download unlock only for the current successful result.

Load the inert sample or enter JSON, then explicitly run.

Hosted API and MCP parity

The same tool ID is available through POST /api/run and the fixed MCP run_tool method. Hosted requests are response-only. This browser workbench does not call either endpoint.
