Use after the readiness verdict is Go and before Monday begins. Produces a two-page artifact the team and Decider sign off on as the contract for the next five days.04 Tool Design Sprint Decide And Storyboardproduct-on-purpose/pm-skillsDay 3 (Wednesday) move of a Design Sprint that runs the art museum layout, heat map, speed critique, straw poll, Decider supervote, rumble-vs-all-in-one decision, and the storyboard that drives Thursday's prototype build. The most decision-heavy day of the sprint. Use Wednesday morning and afternoon after Tuesday's sketches are collected and attribution-stripped. Produces the canonical 5-15 step storyboard that becomes the build spec.04 Tool Design Sprint Map And Targetproduct-on-purpose/pm-skillsDay 1 (Monday) move of a Design Sprint that produces the bundled Monday artifact containing long-term goal, sprint questions (3-7 testable risks), customer or system map (5-15 step flow), expert interview notes, HMW (How Might We) cluster board, and the Decider's chosen target moment. Use Day 1 morning and afternoon after the sprint brief is locked. Sets the design target for Tuesday's sketches and Wednesday's storyboard.04 Tool Design Sprint Prototype Planproduct-on-purpose/pm-skillsDay 4 (Thursday) move of a Design Sprint that produces the planning artifact for the day. Output covers the prototype role plan (Maker, Stitcher, Writer, Asset Collector, Interviewer), prototype brief (what to build, fidelity bar, time allocation per role), canonical Five-Act Interview script (Welcome, Context, Intro, Tasks, Debrief), trial-run checklist, and Friday participant confirmation tracker. The actual prototype build is craft work outside the skill's AI invocation surface. Use Thursday morning after Wednesday's storyboard is signed off.04 Tool Design Sprint Readinessproduct-on-purpose/pm-skillsPre-sprint diagnostic that determines whether a team should run a Design Sprint now, postpone it, or do prerequisite work first. Produces a Go / Conditional Go / Wait verdict with diagnosis, recommended preconditions, attendee list, customer recruiting plan, and pre-sprint activities. Use when a team is considering starting a Design Sprint and wants a fast yes/no diagnosis before committing five days of team time and customer recruiting cost.04 Tool Design Sprint Sketchproduct-on-purpose/pm-skillsDay 2 (Tuesday) move of a Design Sprint that structures lightning demos and the four-step independent solution sketch protocol (Notes, Ideas, Crazy 8s, Solution Sketch). Each team member produces one solution sketch individually; the skill orchestrates the day but does not author the sketches themselves. Use Tuesday morning after Monday's target moment is locked. Output is the lightning demo board, sketch assignments, and the cohort of independent sketches that become Wednesday's heat-map material.04 Tool Design Sprint Test And Scoreproduct-on-purpose/pm-skillsDay 5 (Friday) sprint-closing move of a Design Sprint that produces the bundled Friday artifact covering per-customer interview observations, best quotes, scorecard grid (sprint questions by customers), observed patterns, hot takes from each team member, and the Decider summary (build, iterate, pivot, or stop, plus highest-confidence learning, most important revision, and next artifact). Use Friday after Thursday's prototype passes trial run and during/after the 5 customer interviews. The sprint's payoff artifact.04 Tool Foundation Sprint Approach Optionsproduct-on-purpose/pm-skillsDay 2 morning move of a Foundation Sprint. Forces generation of 3 to 7 candidate approaches as one-page summaries before the team converges on a top bet. Use after Day 1 is signed and before Magic Lenses on Day 2 afternoon. Enforces a minimum of 3 approaches to prevent first-idea anchoring. Each approach summary names what it is, why it serves the differentiators, and includes a simple visual.04 Tool Foundation Sprint Basicsproduct-on-purpose/pm-skillsDay 1 morning move of a Foundation Sprint. Forces explicit team choices on target customer, important problem, team advantage, and competitors and alternatives. Produces a single coherent strategic frame that becomes the input to Day 1 afternoon Differentiation. Use after the sprint brief is signed and Day 1 morning is scheduled. Bundled artifact, not four separate decisions.04 Tool Foundation Sprint Briefproduct-on-purpose/pm-skillsPre-sprint brief that locks scope, the decision the sprint must unlock, team and role assignments, logistics, inputs to bring, and success criteria before Day 1 of a Foundation Sprint. Use after the readiness verdict is Go and before the sprint begins. Produces a one-page artifact the team and Decider sign off on as the contract for the next two days.04 Tool Foundation Sprint Differentiationproduct-on-purpose/pm-skillsDay 1 afternoon move of a Foundation Sprint. Converts the morning's Basics frame into a defensible strategic position by scoring differentiator candidates against customer-perceived value, choosing two committed differentiators, plotting alternatives on a 2x2 chart, writing decision principles, and producing a one-page Mini Manifesto. Use after Basics is signed; before Approach Options the next morning.04 Tool Foundation Sprint Founding Hypothesisproduct-on-purpose/pm-skillsDay 2 end capstone move of a Foundation Sprint. Compresses the sprint's full strategic frame into a single canonical sentence (the Founding Hypothesis) plus an assumption scorecard, why-we-believe, what-could-prove-us-wrong, and recommended next validation step. Use after Magic Lenses is signed. Strict canonical template; paraphrase is not accepted in v0.1.0. The Founding Hypothesis is the spine artifact the sprint exists to produce.04 Tool Foundation Sprint Magic Lensesproduct-on-purpose/pm-skillsDay 2 afternoon move of a Foundation Sprint. Evaluates the candidate approach set through multiple lenses (4 classic plus at least 1 custom) to surface trade-offs, identify consistent winners and contradictions, and produce a top bet plus a backup plan. Use after Approach Options is signed. Lens scoring is a sense-making tool, not mathematical truth; arbitrary precision is a smell.04 Tool Foundation Sprint Readinessproduct-on-purpose/pm-skillsPre-sprint diagnostic that determines whether a team should run a Foundation Sprint now, postpone it, or do prerequisite work first. Produces a Go / Conditional Go / Wait verdict with diagnosis, recommended preconditions, attendee list, and pre-sprint activities. Use when a team is considering starting a Foundation Sprint and wants a fast yes/no diagnosis before committing two days of facilitated work.04 Tool Note And Voteproduct-on-purpose/pm-skillsStructured group-decision mechanic that captures silent ideation, voting summaries, and Decider sign-off in a single bundled artifact. Use when a small team needs to make a fast decision with diverse input, when groupthink is a risk, or when a workshop moment demands silent contribution before discussion. Applicable to Foundation Sprint, Design Sprint, and any participatory decision context.04 Tool UIassistant-ui/tool-uiFind, install, configure, and integrate Tool UI components in React apps using shadcn registry entries, compatibility checks, scaffolded runtime wiring, toolkit setup with assistant-ui, and troubleshooting workflows. Use when developers ask to add one or more Tool UI components, choose components for a use case, verify compatibility, wire a toolkit in a codebase, or integrate Tool UI payloads into assistant-ui or an existing chat/runtime stack.01 Toolsassistant-ui/skillsDefines model-callable tools and renders their calls in assistant-ui. The authoring model: a \"use generative\" file whose default export is defineToolkit({...}), compiled by withAui from @assistant-ui/next, aui() from @assistant-ui/vite, or withAui from @assistant-ui/metro, mounted with AuiConfig({ tools: Tools({ toolkit }) }), and exposed to the model with new AISDKToolkit({ toolkit }).tools({ frontend }). Covers the tool kinds (backend, \"use client\" frontend, humanTool(), providerTool(), externalTool(), stubTool(), defineMcpToolkit()), render and display, ToolCallMessagePartProps, approval gates, MCP servers, MCP Apps, WebMCP, and sub-agent messages. Reach for it when a tool is never called, a tool UI does not render, a frontend result never reaches the model, humanTool() throws at runtime, or an approval gate cannot be answered. For model-composed UI use generative-ui, for MCP servers users add in the browser use react-mcp, and for the styled ToolFallback and ToolGroup use elements.09 Toolslaunchdarkly/ai-toolingGive your agents capabilities through tools (function calling). Helps you identify what your agent needs to do, create tool definitions, and attach them to config variations.02 Tools Page Generatorkostja94/marketing-skillsWhen the user wants to create, optimize, or audit free tools pages. Also use when the user mentions "free tools," "tools page," "toolkit," "free [X] tool," "free [X] calculator," "free [X] checker," "lead magnet tool," "programmatic tools," or "tools hub." For content strategy, use content-strategy.01 Tools UIinference-sh/skillsTool lifecycle UI components for React/Next.js from ui.inference.sh. Display tool calls: pending, progress, approval required, results. Capabilities: tool status, progress indicators, approval flows, results display.

Triggers: tool ui, tool calls, tool status, tool approval, tool results, agent tools, mcp tools ui, function calling ui, tool lifecycle, tool pending01 Tooluniversemims-harvard/tooluniverseToolUniverse plugin router. STEP 1 BEFORE ANY ANALYSIS: if the data folder contains `*_executed.ipynb`, run `tu run read_executed_notebook '{\"data_folder\":\"<path>\",\"search\":\"<keyword>\"}'` to extract its cell outputs and apply EVERY filter/sample-exclusion the notebook used — even when the question says 'Using DESeq2/Run X/Compute Y' (this describes the METHOD the notebook used, not a request to rerun). The notebook's cell outputs are the only published authoritative answers; reimplementing or reading stale pre-computed CSVs in the data folder produces different numbers because of outlier-sample removal, library version, and filter steps you don't see by skimming. STEP 2 routing — pick a sub-skill name from this exact list (never invent): tooluniverse-rnaseq-deseq2 (RNA/miRNA-seq DE, correlation, PCA, clustering, dispersion), tooluniverse-gene-enrichment (GO/KEGG/Reactome/GSEA/pathway enrichment), tooluniverse-statistical-modeling (regression, ANOVA, ordinal/logistic, chi-square, correlation, power), tooluniverse-image-analysis (microscopy, colony, fluorescence, dose-response, .tif — including ANOVA / Dunnett / power-analysis on image-derived measurements), tooluniverse-epigenomics (DNA methylation, CpG, m6A, MeRIP-seq, bisulfite, ChIP-seq, chromatin), tooluniverse-sequence-analysis (FASTQ, Trimmomatic, BWA, samtools, coverage), tooluniverse-variant-analysis (VCF, VAF, SNP, mutation), tooluniverse-phylogenetics (treeness, PhyKIT, parsimony), tooluniverse-single-cell (scRNA, h5ad, scanpy), tooluniverse-crispr-screen-analysis (MAGeCK, sgRNA), tooluniverse-proteomics-analysis (mass spec, TMT).
