Run rigorous alignment sessions that raise the quality bar and accelerate decision-making.
Help the user with effective product reviews using insights from 12 guests and posts across Lenny's Podcast and Newsletter.
From "How Figma builds product": "One thing I encourage for both is to first present the “option space”—it’s really powerful to have a framework that maps all possible solutions or problems and use that as a device to discuss high-level tradeoffs or philosophical differences."
High-quality decisions come from mapping the entire field of possible solutions rather than debating a single proposal in isolation.
From "How Duolingo builds product": "Product review meetings happen every Tuesday and Thursday for a total of two hours. These two hours are divided into 20-minute slots that product teams sign up to present. The agenda of these meetings is product teams presenting their proposed product changes for the first 5 to 10 minutes and then reviewers asking questions and giving feedback for the rest of the time."
Recurring, short review slots prevent feedback bottlenecks and create a shared understanding of what constitutes quality across the organization.
From "How Miro builds product": "Product reviews can focus on different stages of the product development lifecycle: P-Strat: long-term strategy and vision; P0: the opportunity and problem that we want to pursue; P1: the proposed solution; P2: what we launched and how it’s performing."
Structure reviews into distinct stages to ensure leadership agrees on the problem and the strategic direction before teams commit to high-fidelity design work.
From "How Miro builds product": "One of the product leaders came up with the 'Mona Lisa principle'—simply put, everything we ship should be like a Mona Lisa painting, something we’d be proud of putting our name on. . . Every month, they review everything that was shipped and say what is high-quality or not."
Use simple metaphors or principles to build intuition across the team, helping everyone understand the bar for excellence without constant oversight.
From "How Snowflake builds product": "The goal of a product review isn’t to “sell” the leadership team on a new investment but to detail customer requirements, align on relative business priorities, and provide a clear direction of how to address these challenges."
Format reviews as collaborative sessions focused on consistent decision-making rather than internal marketing or selling an idea to leadership.
Tomer Cohen: "I push a lot for what is actually your opinion, what is your potentially controversial opinion and the best principles have teeth. So saying that we should build a simple product for me is useless. Who doesn't want to build a simple product?"
Reviews should be deep-dives into specific problems and principled opinions, avoiding the trap of high-level status updates that provide no strategic value.

Integration with protocols.io API for managing scientific protocols. This skill should be used when working with protocols.io to search, create, update, or publish protocols; manage protocol steps and materials; handle discussions and comments; organize workspaces; upload and manage files; or integrate protocols.io functionality into workflows. Applicable for protocol discovery, collaborative protocol development, experiment tracking, lab protocol management, and scientific documentation.
Analyzes job descriptions and generates tailored resumes that highlight relevant experience, skills, and achievements to maximize interview chances
Generate Excalidraw diagrams from natural language descriptions. Use when asked to "create a diagram", "make a flowchart", "visualize a process", "draw a system architecture", "create a mind map", or "generate an Excalidraw file". Supports flowcharts, relationship diagrams, mind maps, and system architecture diagrams. Outputs .excalidraw JSON files that can be opened directly in Excalidraw.
Build and distribute Expo development clients locally or via TestFlight
Use when you have a written implementation plan to execute in a separate session with review checkpoints
Data structure for annotated matrices in single-cell analysis. Use when working with .h5ad files or integrating with the scverse ecosystem. This is the data format skill—for analysis workflows use scanpy; for probabilistic models use scvi-tools; for population-scale queries use cellxgene-census.
Benchling R&D platform integration. Access registry (DNA, proteins), inventory, ELN entries, workflows via API, build Benchling Apps, query Data Warehouse, for lab data management automation.
Comprehensive molecular biology toolkit. Use for sequence manipulation, file parsing (FASTA/GenBank/PDB), phylogenetics, and programmatic NCBI/PubMed access (Bio.Entrez). Best for batch processing, custom bioinformatics pipelines, BLAST automation. For quick lookups use gget; for multi-service integration use bioservices.
