Design a Collaborative Prompt Playground

Design a collaborative prompt playground where users work on prompts together, preserve versions, and execute selected prompt versions against a model. ### Constraints & Assumptions - The source names a collaborative prompt playground and its collaboration, versioning, and execution flow. It is a third-party compilation, not a supplied company architecture. - **Practice scope:** authenticated project members can edit a shared draft, create immutable versions, launch model runs, and inspect results linked to their exact inputs and configuration. - No required collaboration algorithm, provider, model, scale target, or pricing policy is supplied. - Concurrent editing, retries of run requests, and disconnecting clients must have defined behavior. ### Clarifying Questions to Ask - Is real-time character-level co-editing required, or is conflict-aware document saving sufficient? - What belongs to a version: prompt text, templates, tools, model configuration, or input variables? - Who may edit, execute, share results, or access provider credentials? - Can model runs be canceled or queried after a lost response, and how should uncertain outcomes be shown? ### Part 1 — Collaboration and Versioning Define the draft, revision, and immutable-version model. Explain concurrent edits, reconnection, and the boundary between transient presence and durable document content. #### What This Part Should Cover - An explicit conflict strategy and authorization on edits. - Stable version identity and immutable content/configuration bindings. - No accidental mutation of the version already used by a running experiment. ### Part 2 — Execute and Inspect a Version Describe run creation, model execution, output delivery, and retry behavior. Explain how users compare results without losing their provenance. #### What This Part Should Cover - A run bound to a specific version, inputs, model configuration, and operation identity. - Durable execution state and clear failed or uncertain outcomes. - Separation of collaboration traffic from expensive model work and access to credentials. ```hint Freeze before running Two collaborators can change the draft while a model request is in progress. Decide which exact prompt the resulting output should claim to have executed. ``` ### What a Strong Answer Covers - A coherent collaboration contract and immutable version history. - Reproducible input/configuration provenance without claiming deterministic model outputs. - Safe asynchronous execution, result access, and retry semantics. ### Follow-up Questions - How would you add live co-editing to an initial compare-and-swap save design? - What should happen when a user loses project access while a model run is active? - How can two outputs be compared meaningfully if their prompt or model configurations differ?
