LamindbA--> --- name: bio-lamindb description: This skill should be used when working with LaminDB, an open-source data framework for biology that makes data queryable, traceable, reproducible, and FAIR. Use when managing biological datasets (scRNA-seq, spatial, flow cytometry, etc.), tracking computational workflows, curating and validating data with biological ontologies, building data lakehouses, or ensuring data lineage and reproducibility in biological research. Covers data management, annotatio...databasespythongoVotes: 0GitHub stars: 32

Metabolomics Peak DetectionALoad when running per-sample peak picking on a feature × intensity table via `scipy.signal.find_peaks` — emits per-(sample, feature) detected peaks with prominence and width. Skip when working with mz / RT raw scans (use `metabolomics-xcms-preprocessing` upstream) or when only normalising / quantifying (use `metabolomics-quantification`).databasespythongoVotes: 0GitHub stars: 32

Mongodb ExpertADesigns MongoDB schemas, indexes, and aggregation pipelines that perform - embed-vs-reference decision rules, the 16MB document limit, ESR compound-index ordering, explain-plan verification, and operational settings for replica sets and sharding. Use when someone asks "should I embed or reference this", "why is my Mongo query slow", "design a MongoDB schema for X", "how do I structure this aggregation pipeline", or "what should my shard key be". Do NOT use for relational or SQL schema design ...databasesgosqlVotes: 0GitHub stars: 11
Migration Safety CheckerARewrite a schema migration into independently deployable, zero-downtime steps that never take a long-held blocking lock on a live table. Use when you are about to run an ALTER TABLE, CREATE INDEX, add a constraint, rename a column, or change a column type against a production database with live traffic. Do NOT use for greenfield table/column design with no rows yet - use database-schema instead; do NOT use for broad correctness/integrity review of a migration - use review-db instead.databasesgosqlVotes: 0GitHub stars: 11
Database SchemaADesigns normalized, constrained, migration-friendly relational schemas - entity modeling, key and type selection, indexes derived from real query patterns, and safe forward/rollback migrations. Use when someone asks "design a schema for X", "should I normalize or denormalize this", "what should my primary key be", "how do I add this column without downtime", or "why is my unique constraint broken with soft deletes". Do NOT use for tuning a slow query on an existing schema - use sql-query-opti...databasesgosqlVotes: 0GitHub stars: 11
Connection Pool TunerADiagnoses connection pool exhaustion from captured evidence and sets correct pool sizes and timeouts across app pools and PgBouncer. Use when someone says "we keep hitting database connection limit errors under load", "my API times out waiting for a connection from the pool", "the database shows hundreds of idle connections", or sees "too many clients", checkout/acquire timeouts, "idle in transaction" pile-up, or serverless functions storming the database on a traffic spike. Do NOT use when t...databasesgogitVotes: 0GitHub stars: 11
Strangler Fig PlannerAProduces an incremental migration plan that runs a legacy and a new system side by side behind a routing seam, slicing and sequencing whole capabilities so the old system stays live until its last route is cut. Use when planning to replace or rebuild a large, business-critical system that must keep serving traffic throughout. Do NOT use when extracting a single service from a still-living monolith - use monolith-decomposer instead; for generic non-migration implementation planning, use the pl...databasesgoapiVotes: 0GitHub stars: 2
Trading Strategy BacktesterAWhen the user wants to backtest a quantitative trading strategy based on specific signals, this skill implements strategy logic, executes simulated trades, calculates performance metrics, and generates comprehensive reports. It handles position sizing, transaction costs, holding periods, and computes key metrics like total return, annualized return, Sharpe ratio, win rate, and maximum drawdown. Triggers include backtesting requests, strategy evaluation, or trading performance analysis.databasespythontestingVotes: 0GitHub stars: 8
Zotero VectorizeABuild and maintain a cross-platform local Zotero semantic index using metadata embeddings and PDF full-text chunk embeddings. Use when the user asks to vectorize a Zotero library, create or refresh metadata_vectors.json or fulltext_vectors.json, check for new Zotero items missing from the vector store, incrementally update a Zotero semantic/RAG index, verify vector store counts and sizes, or reproduce this workflow on Windows, macOS, or Linux.databasespythonbashVotes: 0GitHub stars: 8
