Cooking with Constraints: A Designer’s Framework for Better AI Prompts | Figma Blog

Design and cooking both depend on preparation: clear inputs and intentional constraints lead to better outcomes. The article argues that AI models do not need politeness or emotional framing; they need precise instructions that reduce ambiguity. For product designers, structured prompting bridges the gap between probabilistic AI outputs and the repeatable, purposeful results design requires. ## Prompting as Mise en Place - “Mise en place,” or “everything in its place,” means preparing ingredients before cooking—and serves as a useful model for preparing AI prompts. - Effective prompts should establish: - **Clarity** - **Context** - **Constraints** - The author’s framework is **TC-EBC**: - **Task:** What should be built or accomplished? - **Context:** Who is it for and why? - **Elements:** Which features or components are required? - **Behavior:** How should the system respond to user actions? - **Constraints:** What technical, platform, accessibility, or product limits apply? - This approach aligns with broader prompt-engineering guidance emphasizing defined intent, modular construction, and predictable results. ## Why Vague Prompts Underperform - A request such as “build an app that uses pantry photos to suggest recipes” leaves too many decisions to the model. - Polite language and conversational phrasing can bury the actual task without adding useful information. - The resulting prototype may include basic functionality but remain visually generic, uninteresting, and barely beyond a wireframe. ## Applying TC-EBC to a Design Prompt For a pantry-based meal suggestion app, the structured prompt specifies: - **Task:** Build an AI-powered meal suggestion app using pantry and refrigerator photos. - **Context:** Create a home-cooking assistant for households with dietary restrictions. - **Elements:** Include camera input, pantry scanning, dietary settings, meal suggestions, and recipe cards. - **Behavior:** Let users upload photos, scan inventory, apply dietary preferences, and receive recipes. - **Constraints:** Make the experience mobile-first, support iOS and Android, provide accessible UI, and allow multiple household profiles. This structure makes the request easier to scan and gives the model explicit guidance about the app’s purpose, interface, behavior, and limitations. ## Design Requires Structured Uncertainty - LLMs are stochastic, meaning their outputs are probabilistic and variable. - Design, by contrast, depends on precision, consistency, and intentional decisions. - Structured prompts help “collapse uncertainty into structure,” much as a design system provides reusable rules and guidance. - The article presents the TC-EBC prompt as producing a substantially more purposeful prototype than the original one-shot request. A practical recommendation is to treat prompting like preparation for a complex recipe: define the task, provide relevant context, list required parts and behaviors, and state constraints before asking the AI to generate a design.

Daangn's GenAI Platform (opens in new tab)

Daangn has scaled its Generative AI capabilities from a few initial experiments to hundreds of diverse use cases by building a robust, centralized internal infrastructure. By abstracting model complexity and empowering non-technical stakeholders, the company has optimized API management, cost tracking, and rapid product iteration. The resulting platform ecosystem allows the organization to focus on delivering product value while minimizing the operational overhead of managing fragmented AI services. ### Centralized API Management via LLM Router Initially, Daangn faced challenges with fragmented API keys, inconsistent rate limits across teams, and the inability to track total costs across multiple providers like OpenAI, Anthropic, and Google. The LLM Router was developed as an "AI Gateway" to consolidate these resources into a single point of access. * **Unified Authentication:** Service teams no longer manage individual API keys; they use a unique Service ID to access models through the router. * **Standardized Interface:** The router uses the OpenAI SDK as a standard interface, allowing developers to switch between models (e.g., from Claude to GPT) by simply changing the model name in the code without rewriting implementation logic. * **Observability and Cost Control:** Every request is tracked by service ID, enabling the infrastructure team to monitor usage limits and integrate costs directly into the company’s internal billing platform. ### Empowering Non-Engineers with Prompt Studio To remove the bottleneck of needing an engineer for every prompt adjustment, Daangn built Prompt Studio, a web-based platform for prompt engineering and testing. This tool enables PMs and other non-developers to iterate on AI features independently. * **No-Code Experimentation:** Users can write prompts, select models (including internally served vLLM models), and compare outputs side-by-side in a browser-based UI. * **Batch Evaluation:** The platform includes an Evaluation feature that allows users to upload thousands of test cases to quantitatively measure how prompt changes impact output quality across different scenarios. * **Direct Deployment:** Once a prompt is finalized, it can be deployed via API with a single click. Engineers only need to integrate the Prompt Studio API once, after which non-engineers can update the prompt or model version without further code changes. ### Ensuring Service Reliability and Stability Because third-party AI APIs can be unstable or subject to regional outages, the platform incorporates several safety mechanisms to ensure that user-facing features remain functional even during provider downtime. * **Automated Retries:** The system automatically identifies retry-able errors and re-executes requests to mitigate temporary API failures. * **Region Fallback:** To bypass localized outages or rate limits, the platform can automatically route requests to different geographic regions or alternative providers to maintain service continuity. ### Recommendation For organizations scaling AI adoption, the Daangn model suggests that investing early in a centralized gateway and a no-code prompt management environment is essential. This approach not only secures API management and controls costs but also democratizes AI development, allowing product teams to experiment at a pace that is impossible when tied to traditional software release cycles.

How AI Is Transforming the Adoption of Secure-by-Default Mobile Frameworks (opens in new tab)

Meta utilizes secure-by-default frameworks to wrap potentially unsafe operating system and third-party functions, ensuring security is integrated into the development process without sacrificing developer velocity. By leveraging generative AI and automation, the company scales the adoption of these frameworks across its massive codebase, effectively mitigating risks such as Android intent hijacking. This approach balances high-level security enforcement with the practical need for friction-free developer experiences. ## Design Principles for Secure-by-Default Frameworks To ensure high adoption and long-term viability, Meta follows specific architectural guidelines when building security wrappers: * **API Mirroring:** Secure framework APIs are designed to closely resemble the existing native APIs they replace (e.g., mirroring the Android Context API). This reduces the cognitive burden on developers and simplifies the use of automated tools for code conversion. * **Reliance on Public Interfaces:** Frameworks are built exclusively on public and stable APIs. Avoiding private or undocumented OS interfaces prevents maintenance "fire drills" and ensures the frameworks remain functional across various OS updates. * **Modularity and Reach:** Rather than creating a single monolithic tool, Meta develops small, modular libraries that target specific security issues while remaining usable across all apps and platform versions. * **Friction Reduction:** Frameworks must avoid introducing excessive complexity or noticeable performance overhead in terms of CPU and RAM, as high friction often leads developers to bypass security measures entirely. ## SecureLinkLauncher: Preventing Android Intent Hijacking SecureLinkLauncher (SLL) is a primary example of a secure-by-default framework designed to stop sensitive data from leaking via the Android intent system. * **Wrapped Execution:** SLL wraps native Android methods such as `startActivity()` and `startActivityForResult()`. Instead of calling `context.startActivity(intent)`, developers use `SecureLinkLauncher.launchInternalActivity(intent, context)`. * **Scope Verification:** The framework enforces scope verification before delegating to the native API. This ensures that intents are directed to intended "family" apps rather than being intercepted by malicious third-party applications. * **Mitigating Implicit Intents:** SLL addresses the risks of untargeted intents, which can be received by any app with a matching intent-filter. By enforcing a developer-specified scope, SLL ensures that data like `SECRET_INFO` is only accessible to authorized packages. ## Scaling Adoption through AI and Automation The transition from legacy, insecure patterns to secure frameworks is managed through a combination of automated tooling and artificial intelligence. * **Automated Migration:** Generative AI identifies insecure usage patterns across Meta’s vast codebase and suggests—or automatically applies—the appropriate secure framework replacements. * **Continuous Monitoring:** Automation tools continuously scan the codebase to ensure compliance with secure-by-default standards, preventing the reintroduction of vulnerable code. * **Scaling Consistency:** By reducing the manual effort required for refactoring, AI enables consistent security enforcement across different teams and applications without slowing down the shipping cycle. For organizations managing large-scale mobile codebases, the recommended approach is to build thin, developer-friendly wrappers around risky platform APIs and utilize automated refactoring tools to drive adoption. This ensures that security becomes an invisible, default component of the development lifecycle rather than a manual checklist.

Gemini provides automated feedback for theoretical computer scientists at STOC 2026 (opens in new tab)

Google Research launched an experimental program for the STOC 2026 conference using a specialized Gemini model to provide automated, rigorous feedback on theoretical computer science submissions. By identifying critical logical errors and proof gaps within a 24-hour window, the tool demonstrated that advanced AI can serve as a powerful pre-vetting collaborator for high-level mathematical research. The overwhelmingly positive reception from authors indicates that AI can effectively augment the human peer-review process by improving paper quality before formal submission. ## Advanced Reasoning via Inference Scaling - The tool utilized an advanced version of Gemini 2.5 Deep Think specifically optimized for mathematical rigor. - It employed inference scaling methods, allowing the model to explore and combine multiple possible solutions and reasoning traces simultaneously. - This non-linear approach to problem-solving helps the model focus on the most salient technical issues while significantly reducing the likelihood of hallucinations. ## Structured Technical Feedback - Feedback was delivered in a structured format that included a high-level summary of the paper's core contributions. - The model provided a detailed analysis of potential mistakes, specifically targeting errors within lemmas, theorems, and logical proofs. - Authors also received a categorized list of minor corrections, such as inconsistent variable naming and typographical errors. ## Identified Technical Issues and Impact - The pilot saw high engagement, with over 80% of STOC 2026 submitters opting in for the AI-generated review. - The tool successfully identified "critical bugs" and calculation errors that had previously evaded human authors for months. - Survey results showed that 97% of participants found the feedback helpful, and 81% reported that the tool improved the overall clarity and readability of their work. ## Expert Verification and Hallucinations - Because the users were domain experts, they were able to act as a filter, distinguishing between deep technical insights and occasional model hallucinations. - While the model sometimes struggled to parse complex notation or interpret figures, authors valued the "neutral tone" and the speed of the two-day turnaround. - The feedback was used as a starting point for human verification, allowing researchers to refine their arguments rather than blindly following the model's output. ## Future Outlook and Educational Potential - Beyond professional research, 75% of surveyed authors see significant educational value in using the tool to train students in mathematical rigor. - The experiment's success has led to 88% of participants expressing interest in having continuous access to such a tool throughout their entire research and drafting process. The success of the STOC 2026 pilot suggests that researchers should consider integrating specialized LLMs early in the drafting phase to catch "embarrassing" or logic-breaking errors. While the human expert remains the final arbiter of truth, these tools provide a necessary layer of automated verification that can accelerate the pace of scientific discovery.

The December 8, 2025, AWS Weekly Roundup recaps the major themes from AWS re:Invent, signaling a significant industry transition from AI assistants to autonomous AI agents. While technical innovation in infrastructure remains a priority, the event underscored that developers remain at the heart of the AWS mission, empowered by new tools to automate complex tasks using natural language. This shift represents a "renaissance" in cloud computing, where purpose-built infrastructure is now designed to support the non-deterministic nature of agentic workloads. ## Community Recognition and the Now Go Build Award * Raphael Francis Quisumbing (Rafi) from the Philippines was honored with the Now Go Build Award, presented by Werner Vogels. * A veteran of the ecosystem, Quisumbing has served as an AWS Hero since 2015 and has co-led the AWS User Group Philippines for over a decade. * The recognition emphasizes AWS's continued focus on community dedication and the role of individual builders in empowering regional developer ecosystems. ## The Evolution from AI Assistants to Agents * AWS CEO Matt Garman identified AI agents as the next major inflection point for the industry, moving beyond simple chat interfaces to systems that perform tasks and automate workflows. * Dr. Swami Sivasubramanian highlighted a paradigm shift where natural language serves as the primary interface for describing complex goals. * These agents are designed to autonomously generate plans, write necessary code, and call various tools to execute complete solutions without constant human intervention. * AWS is prioritizing the development of production-ready infrastructure that is secure and scalable specifically to handle the "non-deterministic" behavior of these AI agents. ## Core Infrastructure and the Developer Renaissance * Despite the focus on AI, AWS reaffirmed that its core mission remains the "freedom to invent," keeping developers central to its 20-year strategy. * Leaders Peter DeSantis and Dave Brown reinforced that foundational attributes—security, availability, and performance—remain the non-negotiable pillars of the AWS cloud. * The integration of AI agents is framed as a way to finally realize material business returns on AI investments by moving from experimental use cases to automated business logic. To maximize the value of these updates, organizations should begin evaluating how to transition from simple LLM implementations to agentic frameworks that can execute end-to-end business processes. Reviewing the on-demand keynote sessions from re:Invent 2025 is recommended for technical teams looking to implement the latest secure, agent-ready infrastructure.

On the (re)-prioritization of open-source AI

Pinterest argues that AI competition is shifting beyond ever-larger proprietary models. Open-source models now deliver comparable quality at a fraction of the cost, while compact models fine-tuned for specific tasks can outperform general-purpose systems. The company’s strategy is to combine open-source models with Pinterest-specific data, internal systems, and deep product integration. ## Open-Source Models and Cost Efficiency - Pinterest reports achieving performance comparable to leading proprietary AI models at less than 10% of the cost. - The company is shifting more investment toward fine-tuned open-source models, especially for visual and multimodal applications. - As core LLM architectures become increasingly commoditized, competitive advantage is moving toward: - Domain-specific data - Personalization - Product integration - End-to-end system optimization ## Choosing What to Build, Buy, or Adapt Pinterest evaluates foundation-model strategy by modality: - **User modeling and recommendation** - These systems are tightly coupled to a product’s behavior and are generally built internally. - Pinterest uses long-term user-action sequences and a graph containing hundreds of billions of user, board, and content nodes. - Examples include PinFM for representation learning and PinRec for generative recommendations. - **Visual models** - Pinterest largely trains visual encoders and diffusion models in-house. - Its visual-search data and image-board collections provide the weakly supervised datasets needed for large-scale training. - Internal models benefit from Pinterest’s specialized visual domain. - **Text models** - Pinterest has historically relied more on open-source and proprietary third-party LLMs. - Progress in reasoning and language modeling depends heavily on enormous datasets and compute resources, making external models practical. ## Domain-Specific Data as the Differentiator - Open-source multimodal architectures are narrowing the capability gap with proprietary models. - Pinterest’s experience reflects an older machine-learning pattern: model architectures become broadly available, while value comes from specialized data and fine-tuning. - Its visual encoders, including UVE and PinCLIP, improved retrieval by training on Pinterest image and visual-search data rather than using generic embeddings. - Pinterest Canvas similarly adapts an internally trained diffusion model for image editing and enhancement, outperforming larger general-purpose visual-generation models in those use cases. ## Pinterest Assistant and Specialized Tools - Pinterest Assistant combines: - Multimodal retrieval systems - Recommendation services - Specialized generative models - A core multimodal LLM - Most recommendation and agentic capabilities are handled by Pinterest-native tools built on its user and visual foundation models. - The central LLM acts primarily as an intelligent router, handling query understanding, planning, and tool calling rather than performing every task itself. - This architecture allows Pinterest to improve the overall product by optimizing smaller, specialized components instead of relying solely on a larger general-purpose model. Pinterest’s recommendation is to use open-source models as adaptable building blocks, then differentiate through proprietary data, specialized models, and tight integration with the product. The most effective AI systems may therefore be smaller, cheaper, and more purpose-built than frontier general-purpose models.

Amazon Bedrock adds reinforcement fine-tuning simplifying how developers build smarter, more accurate AI models (opens in new tab)

Amazon Bedrock has introduced reinforcement fine-tuning, a new model customization capability that allows developers to build more accurate and cost-effective AI models using feedback-driven training. By moving away from the requirement for massive labeled datasets in favor of reward signals, the platform enables average accuracy gains of 66% while automating the complex infrastructure typically associated with advanced machine learning. This approach allows organizations to optimize smaller, faster models for specific business needs without sacrificing performance or incurring the high costs of larger model variants. **Challenges of Traditional Model Customization** * Traditional fine-tuning often requires massive, high-quality labeled datasets and expensive human annotation, which can be a significant barrier for many organizations. * Developers previously had to choose between settle for generic "out-of-the-box" results or managing the high costs and complexity of large-scale infrastructure. * The high barrier to entry for advanced reinforcement learning techniques often required specialized ML expertise that many development teams lack. **Mechanics of Reinforcement Fine-Tuning** * The system uses an iterative feedback loop where models improve based on reward signals that judge the quality of responses against specific business requirements. * Reinforcement Learning with Verifiable Rewards (RLVR) utilizes rule-based graders to provide objective feedback for tasks such as mathematics or code generation. * Reinforcement Learning from AI Feedback (RLAIF) uses AI-driven evaluations to help models understand preference and quality without manual human intervention. * The workflow can be powered by existing API logs within Amazon Bedrock or by uploading training datasets, eliminating the need for complex infrastructure setup. **Performance and Security Advantages** * The technique achieves an average accuracy improvement of 66% over base models, enabling smaller models to perform at the level of much larger alternatives. * Current support includes the Amazon Nova 2 Lite model, which helps developers optimize for both speed and price-to-performance. * All training data and customization processes remain within the secure AWS environment, ensuring that proprietary data is protected and compliant with organizational security standards. Developers should consider reinforcement fine-tuning as a primary strategy for optimizing smaller models like Amazon Nova 2 Lite to achieve high-tier performance at a lower cost. This capability is particularly recommended for specialized tasks like reasoning and coding where objective reward functions can be used to rapidly iterate and improve model accuracy.
