Data & Analytics

gulmezeren2-byte Skill

Query construction, N+1 detection and migration safety for Django: select_related vs prefetch_related, when a migration needs a separate data step, and how to read the SQL a queryset actually emits.

brandonburrus Bundle

This skill should be used when analyzing, aggregating, summarizing, or plotting tabular data from CSV, TSV, Excel, JSON, Parquet, or SQLite sources. It applies when the user says "analyze this data", "what's the total/average/trend", "group by", "how many rows", "plot this", "make a chart from this data", hands over a data file with a question, or wants an analysis notebook for the exploration. It should not be used for editing spreadsheet files as documents (use edit-excel-sheet), designing database schemas (use spec), architecture diagrams (use create-diagram), or building an interactive or custom data visualization as the deliverable (use visualize-data).

brandonburrus Bundle

This skill should be used after a feature or product ships, to turn usage and product data into a ship / iterate / roll-back decision with statistical honesty. It applies when the user says "did the launch work", "analyze the metrics", "read the A/B test", "is this experiment significant", "should we ship the variant", "funnel analysis", "retention / cohort analysis", "why did activation drop", "what's our north-star metric", "the feature is live, now what", or "are these numbers real". It should not be used for generic tabular data crunching with no product decision attached (use analyze-data), for pre-launch market sizing from desk research (use research-market), for pre-build demand validation before anything exists (use validate-idea), or for building a dashboard or custom visualization as the deliverable (use visualize-data).

brandonburrus Bundle

This skill should be used when creating, editing, or reading Excel spreadsheets (.xlsx, .xlsm) including cell values, formulas, formatting, multiple sheets, tables, and charts. It applies when the user says "create a spreadsheet", "update this Excel file", "read the xlsx", "add a column to the sheet", or references a .xlsx/.xlsm file. It should not be used for plain .csv files (edit them as text), for legacy .xls files without converting first, or for analyzing tabular data where the spreadsheet is only the container (load it and analyze directly).

amplitude Skill

Set up measurement and tracking for product launches, run post-launch retros with data, and build a launch analytics system. Use this skill whenever someone asks to track a launch, set up UTM parameters, measure launch performance, run a launch retro, analyze launch results, or build a dashboard for a product release. Also trigger for "how do we know if the launch worked," "what should we track for this launch," "set up UTMs for the announcement," or any request about measuring or evaluating a product launch. Covers pre-launch tracking setup, UTM conventions, per-tier KPIs, benchmark expectations, and retro frameworks.

amplitude Skill

Instruments a pull request with Amplitude analytics that conform to the project's existing taxonomy. Reads the tracking plan via the Amplitude MCP server (events, properties, naming conventions), analyzes the PR diff to find the few user actions genuinely worth tracking, detects the codebase's SDK and tracking patterns, and adds instrumentation that matches both. Optionally (opt-in) stages new events and properties on an Amplitude tracking-plan branch for data-governance review. Use when asked to "instrument this PR", "add analytics to this change", "add tracking", "add Amplitude events", "instrument this feature", or "what should I track here".

amplitude Skill

Analyze MCP server usage instrumented with Amplitude's MCP Analytics SDK: break usage and errors down by tool, read the rationales within each tool to see what callers are trying to do, and produce a prioritized write-up of actionable fixes. Use this skill whenever the user asks to understand how their MCP server is being used, what agents/users are trying to do with it, why tool calls are failing, what to fix or improve in their MCP server, or asks for an "MCP usage report", "tool error analysis", "intent analysis", "rationale clustering", or "MCP insights". Also trigger when the user mentions [MCP]-prefixed events, tool rationale, tool call errors, or just finished instrumenting their MCP server and wants to see what the data says. Requires the Amplitude MCP connector.
