Data & Analytics

amplitude Bundle

Guide an Amplitude user through building a custom agent by suggesting use cases grounded in their role and data, shaping the idea into a well-formed spec, and generating a ready-to-run Global Agent deeplink that creates it. Use to create, build, or set up a custom agent, automate a recurring analysis, or put a repeated report on a schedule.

amplitude Skill

Diagnoses product health by cross-referencing Amplitude analytics (dashboards, charts, funnels, feedback, AI agent analytics), optionally Datadog (errors, latency, stack traces), and optionally Slack (qualitative feedback, bug reports, feature requests). Identifies what's broken, what's working, and what to do about it — with root causes, not just symptoms. Use when asked to "diagnose my product", "what's going on", "product health check", "what's broken", "where are users struggling", "give me a product diagnosis", or "what should I focus on".

amplitude Skill

Instrument a Node/TypeScript MCP server with Amplitude's @amplitude/mcp-analytics SDK so tool calls, sessions, and rationale are tracked as Amplitude events. Use this skill whenever the user wants to add Amplitude analytics to their MCP server, mentions "MCP Analytics", "@amplitude/mcp-analytics", "instrument my MCP server", "track MCP tool calls", "add rationale to my MCP tools", or wants agent traffic (Claude, Cursor, ChatGPT) attributed back to Amplitude. Also use for adding UTM tagging to MCP-returned links, or for troubleshooting identity/user_id mismatches between MCP events and web/mobile Amplitude data.

amplitude Skill

Pull Intercom tickets and Slack support messages from the past 7 days, classify each signal, enrich with CRM data (ARR, plan, renewal), score by customer value and churn risk, and output a tiered priority report saved to Drive. Use when you need a fast, data-driven view of what support signals matter most.

cgyudistira Skill

Advanced pandas operations, performance optimization, and data wrangling.

hoanganhduc Bundle

Use when identifying a journal, conference, or proceedings series from a partial name, acronym, alias, ISSN, or source ID; preserving source-specific rank, quartile, metric, classification, membership, or coverage observations; or proving that the public ICORE detail page displayed one ICORE claim. Live bulk paths are ICORE (edition-verified) and DOAJ (public CSV, currentness-unconfirmed). Other built-ins accept authorized normalized imports only; Conference Ranks is legacy. Return every plausible match and never conflate index membership with ranking.

🗄️ Database Migration Master Skill

k-dense-ai Bundle

Applies the epidemiological reasoning and population-health frameworks of Albert Hofman (Harvard epidemiologist, Rotterdam Study). Trigger this skill whenever you are analyzing public health strategies, preventive medicine, cohort study design, cardiovascular or neurodegenerative disease risks, or healthy aging. Use it when evaluating whether to use population-wide interventions versus individual screening, assessing risk factors in elderly populations, or tracing adult chronic diseases back to early-life or fetal origins.

k-dense-ai Bundle

Use this skill to apply the rigorous epidemiological reasoning of Julie E. Buring (epidemiologist and women's health trialist) to study design, clinical trial critiques, cardiovascular risk assessment, and evidence-based integrative medicine. Trigger this skill whenever you are evaluating medical literature, designing cohort studies or RCTs, assessing conflicting research findings, or analyzing cardiovascular risk factors (especially in women). Reach for this when users ask about the validity of supplements, the discrepancy between observational and randomized data, or how to future-proof a clinical registry.

stephenrogan Skill

Takes raw usage data -- even a spreadsheet export or pasted metrics -- and identifies patterns, risks, and opportunities. Translates product analytics into account intelligence a CSM can act on. Use when asked to interpret usage data, analyse product metrics, make sense of a usage report, identify trends in customer behaviour, flag usage-based risks, or when a CSM has data but does not know what it means for the account. Also triggers for questions about usage analysis, product analytics interpretation, behavioural pattern detection, usage-based risk identification, or turning raw metrics into actionable insight.

Requirements for Outputs

uxcel-lab Skill

Design or critique an analytics or data dashboard — which metrics earn a place, how to organize and prioritize them, and which chart fits each one. Trigger when designing a dashboard, building an analytics or reporting screen, choosing chart types, or reviewing a dashboard for clarity and information overload.

uxcel-lab Skill

Run a product-analytics analysis that produces a decision, not a dashboard — start from the question, pick actionable over vanity metrics, separate signal from noise, segment (averages lie), pair quant with qual, and end in an insight→impact→action story. Catches the defaults Claude misses: vanity metrics, correlation-as-causation, reacting to small samples/short windows, survivorship/selection bias, unsegmented averages. Trigger when asked to analyze product data/metrics, plan what to measure, build a funnel/cohort/segment/retention analysis, read analytics, or turn data into a recommendation.

matejformanek Skill

Pick the right PostgreSQL test flavor for a core / contrib patch — covers pg_regress .sql / .out pairs, isolationtester specs and permutations for concurrency / deadlock races, TAP (PostgreSQL::Test::Cluster) for multi-node and pg_basebackup / replication / recovery scenarios, and src/test/modules for in-tree C test modules. Spans where test files live, how to wire them into the right schedule / meson.build, and how to run a single test fast (REGRESS_OPTS, --temp-instance, PROVE_FLAGS). Use whenever adding tests to a PG patch, reviewing a patch's test coverage, picking between regress / isolation / TAP for a new feature, debugging a regression diff, or asked "where should the test for X live". Skip for pytest / unittest / Jest / Vitest / Mocha / RSpec / JUnit / Go testing / Rust cargo-test app testing, pgbench / sysbench / HammerDB performance benchmarking, end-to-end / Selenium / Playwright web testing, and load / stress testing of production PG.

matejformanek Skill

Debug a running PostgreSQL backend with lldb / gdb — covers attaching to the right forked backend via pg_backend_pid, single-user mode for postmaster / InitPostgres startup paths, breakpoints in ExecInitNode / heap_update / LWLockAcquire, elog(LOG, ...) printf-debugging, macOS / Linux core-dump configuration, and SQL-level inspection via pg_buffercache / pageinspect / pg_visibility. Use whenever the user wants to step through backend C code, attach lldb / gdb to a specific dev-cluster backend, chase a SIGSEGV / hang / loop / assertion-failure in PG, instrument with elog, inspect shmem / buffer / lock state at runtime, or read a PG core dump. Skip for app-level debugging in Node.js / Python / Ruby / Go / Rust (use language-specific debuggers), JVM hprof / jstack, browser DevTools, Chrome Tracing, application performance profiling, and production PG tuning (autovacuum / shared_buffers — that's DBA work).

matejformanek Skill

Write a SQL-callable C function or call PostgreSQL fmgr / SPI from C — covers PG_FUNCTION_INFO_V1, PG_GETARG_* / PG_RETURN_*, PG_ARGISNULL, SRF_* set-returning function ValuePerCall and Materialize modes, composite / polymorphic returns, DirectFunctionCall* / OidFunctionCall* / FunctionCallInvoke fmgr entry points, plus SPI_connect / SPI_execute / SPI_prepare / SPI_finish, plan caching, SPI cursors, subxact rollback, and SPI return codes. Use whenever a PG patch or extension adds a `Datum foo(PG_FUNCTION_ARGS)` entry point, exposes a set-returning function, calls fmgr from backend C, or embeds SQL via SPI in a backend / trigger / PL handler. Skip for plpgsql / PL/Python / PL/Perl user-side function authoring, libpq / psycopg / JDBC / node-postgres client-side query execution, generic executor questions (use executor-and-planner), and non-PG embedded SQL (Oracle OCI, SQLite C API).

matejformanek Skill

PostgreSQL's Free Space Map (FSM) — the tree-of-pages that tracks per-heap-page free space so `INSERT` / `COPY` / `heap_multi_insert` can find a page with room without scanning the whole relation. Covers `src/backend/storage/freespace/` (`freespace.c` + `fsmpage.c` + `indexfsm.c`), the tree layout (leaf-page nodes + 2 upper levels), category encoding (bucketed free-byte counts), the FSM lock discipline, VACUUM's post-scan `FreeSpaceMapVacuum`, and index FSM's simpler use case. Skip when the ask is about visibility map (VM — sibling but different subsystem) or about `pg_freespacemap` contrib module (that's the SQL introspection wrapper).

matejformanek Skill

Add parallel-aware C code in a PostgreSQL backend patch or extension — covers ParallelContext lifecycle (EnterParallelMode / CreateParallelContext / InitializeParallelDSM / LaunchParallelWorkers / WaitForParallelWorkersToFinish / DestroyParallelContext / ExitParallelMode), shm_toc DSM allocation + key lookup, ExecXXXInitializeDSM / ExecXXXInitializeWorker / ExecXXXReInitializeDSM hooks on plan nodes, and parallel-safety markings (pg_proc.proparallel s/r/u; PARALLEL SAFE / RESTRICTED / UNSAFE). Use whenever a PG patch or extension adds parallel-aware code, picks PARALLEL SAFE/RESTRICTED/UNSAFE for a SQL-callable function, extends execParallel.c, plumbs a worker shmem state via shm_toc, or debugs a parallel worker DSM/TOC issue. Skip for DBA tuning of max_parallel_workers GUC, OpenMP / CUDA / pthread / Tokio / Go-goroutine parallelism, JavaScript Promise.all and async-iter parallel fetches, generic worker-pool questions, and ML data-parallel training.
