Given a product description, category keywords, or competitor names (any combination), searches Reddit, Hacker News, GitHub Issues, G2, and Google Trends for the real pains your market experiences, then synthesizes everything into a positioning framework showing who your ICP is, what they say out loud, and exactly how to talk to them. Use when asked to understand a market, find ICP pain points, map competitors, build a positioning doc, find messaging angles, or answer who is my customer and what do they actually care about. Trigger when a user says map my market, who is my ICP, what pains does my market have, understand my market, find my target customer, what are the top complaints in X space, help me position my product, or who should I be selling to.
'Takes a startup product URL or description, detects the industry and funding stage, identifies 5 comparable funded companies, searches who invested in those companies (Track A), finds VCs who publish investment theses about this space (Track B), and returns a ranked sourced list of relevant investors with deep-dives and outreach hooks. Use when asked to find investors for a startup, identify which VCs fund products like mine, research who backs companies in my space, build a VC target list, or find investor-market fit.'

Use when writing concurrent Go code — goroutines, channels, mutexes, or thread-safety guarantees. Also use when parallelizing work, fixing data races, or protecting shared state, even if the user doesn't explicitly mention concurrency primitives. Does not cover context.Context patterns (see go-context).
Use when writing conditionals, loops, or switch statements in Go — including if with initialization, early returns, for loop forms, range, switch, type switches, and blank identifier patterns. Also use when writing a simple if/else or for loop, even if the user doesn't mention guard clauses or variable scoping. Does not cover error flow patterns (see go-error-handling).
Use when working with Go slices, maps, or arrays — choosing between new and make, using append, declaring empty slices (nil vs literal for JSON), implementing sets with maps, and copying data at boundaries. Also use when building or manipulating collections, even if the user doesn't ask about allocation idioms. Does not cover concurrent data structure safety (see go-concurrency).
Use when choosing a logging approach, configuring slog, writing structured log statements, or deciding log levels in Go. Also use when setting up production logging, adding request-scoped context to logs, or migrating from log to slog, even if the user doesn't explicitly mention logging. Does not cover error handling strategy (see go-error-handling).
Use when naming any Go identifier — packages, types, functions, methods, variables, constants, or receivers — to ensure idiomatic, clear names. Also use when a user is creating new types, packages, or exported APIs, even if they don't explicitly ask about naming conventions. Does not cover package organization (see go-packages).
