This skill should be used when the user asks to "release my game", "ship it", "publish to itch.io", "prepare for launch", "is my game ready to release", "make a store page", "release checklist", "version my game", "what do I need before launching", "post-launch", "my game is live and I need to update it", or is preparing a Phaser game for players rather than for testing.
Use when writing modern PHP 8.x code — enums, fibers, readonly properties, PSR standards, Composer, static analysis, SOLID patterns. Trigger conditions: PHP code authoring, enum design, readonly DTO creation, PSR-4 autoloading setup, PHPStan or Psalm configuration, PHP CS Fixer or Pint setup, Composer dependency management, SOLID principle application, type safety improvements, custom exception hierarchies, interface-driven design.
Build with and use Pi, the minimal terminal coding harness. Use for installing Pi, configuring providers/models/settings/environment variables, creating Pi skills/extensions/packages/themes/prompt templates, embedding Pi through the SDK, integrating over RPC or JSON event streams, parsing sessions, running local models through the llama.cpp router, developing custom Pi providers and TUI components, or using ecosystem packages such as pi-subagents (delegation/orchestration), pi-mcp-adapter (MCP servers), pi-interview (interactive forms), and pi-web-access (web search, fetching, video understanding).
Use when starting any implementation task, feature request, bug fix, or refactoring work. Triggers on /plan command, before any code is written, when requirements need structured analysis, or when transitioning from brainstorming to implementation. Forces question-asking, approach comparison, and explicit approval before any code.
Use when: you need creative ideas, product direction exploration, divergent thinking, or root-cause problem analysis; the user says "I want to build an XX", "help me plan an XX product", or "help me design the requirements"; the user gives a new product direction but has not yet completed this round of interactive brainstorm confirmation; or it is the first step of a new product from 0 to 1. Do NOT use when: the user explicitly says "skip brainstorm / go straight to requirements research / brainstorm is already done", or the requirements are already clear and the user explicitly asks to directly run a specific follow-up skill
Use when: you need to produce PRD/BRD/MRD product documents, solution documents, or business plan documents, or you need document templates. Do NOT auto-select when: the user makes a new product request in natural language such as "write a requirements document", "write a PRD", or "help me design the requirements" → these must first be routed to start-super-pm. Direct slash-command use is allowed: when the user explicitly types /pm-docs they can enter directly, but the prerequisite gate of this skill must still be passed. Do NOT use when: the document is already complete and needs no generation, or only verbal discussion is needed with no written output
Creates strategic portfolio roadmaps that size and sequence initiative bets across time horizons (H1/H2/H3), balance risk profiles (core/adjacent/transformational), and set clear exit/scale criteria for disciplined resource allocation. Use when managing multiple initiatives across time horizons, balancing risk vs return across portfolio, sizing and sequencing bets with dependencies, setting exit/scale criteria for experiments, allocating resources across innovation types, or when user mentions portfolio planning, roadmap horizons, betting framework, initiative prioritization, innovation portfolio, or resource allocation across horizons.
Guides PostgreSQL development including table design, indexing, constraints, PL/pgSQL, JSONB, full-text search, window functions, CTEs, EXPLAIN ANALYZE tuning, backup/restore, replication, and extensions like pgvector. Use when the user needs to write or optimize PostgreSQL queries, design schemas, or manage PostgreSQL databases.
Every Google Trends workflow pytrends offered, plus the local history and rate-limit resilience that archived, frozen wrapper never had. Trigger phrases: `check google trends for`, `interest over time for`, `what's trending right now`, `compare search interest`, `related queries for`, `search interest by region`, `use google-trends`, `run google-trends-pp-cli`.
Discover and apply curated prompts from the prompts.chat collection to optimize AI interactions. Use when refining prompt engineering, finding domain-specific prompt templates, improving response quality, or building prompt-based workflows. Triggers on: prompt optimization, prompt templates, prompt engineering, prompt library, curated prompts, prompt discovery, and AI prompt patterns.
Creates Pulumi infrastructure-as-code projects in Go, configures OIDC authentication, integrates with Pulumi ESC for centralized secrets and configuration management, and builds multi-language component resources. Use when setting up Pulumi Go projects, writing infrastructure code with Go, configuring OIDC for Pulumi, using Pulumi ESC with Go, automating cloud infrastructure with Golang, creating reusable Pulumi components in Go, or working with pulumi-go-provider. Also use when the user mentions Pulumi with Go/Golang, AWS/Azure/GCP infrastructure in Go, or Go-based ComponentResource patterns.
Interactive QA session where user reports bugs or issues conversationally, and the agent files GitHub issues. Explores the codebase in the background for context and domain language. Use when user wants to report bugs, do QA, file issues conversationally, or mentions "QA session".
James Bach's HTSM Product Factors (SFDIPOT) analysis for comprehensive test strategy generation. Use when analyzing requirements, epics, or user stories to generate prioritized test ideas across Structure, Function, Data, Interfaces, Platform, Operations, and Time dimensions.
Evidence-based investigative code review using deductive reasoning to determine what actually happened versus what was claimed. Use when verifying implementation claims, investigating bugs, validating fixes, or conducting root cause analysis. Elementary approach to finding truth through systematic observation.
Advanced visual regression testing with pixel-perfect comparison, AI-powered diff analysis, responsive design validation, and cross-browser visual consistency. Use when detecting UI regressions, validating designs, or ensuring visual consistency
Expert quantitative analyst specializing in financial modeling, algorithmic trading, and risk analytics. Masters statistical methods, derivatives pricing, and high-frequency trading with focus on mathematical rigor, performance optimization, and profitable strategy development.
Execute small, well-understood changes directly in the current session with minimal ceremony and ponytail taste. Use when explicitly requested, or automatically for localized fixes, mechanical edits, config tweaks, and short scripts with clear behavior and a known verification path. No plan documents or grilling; do not add tests by default. Prefer steady-do when design, compatibility, or acceptance decisions remain; prefer plan-brief when planning and execution need a separate-session handoff.
Reverse engineering binaries using radare2 (r2). Analyze executables, disassemble code, find functions, extract strings, patch binaries, debug programs, and explore firmware. Supports persistent sessions for large binaries to avoid re-analysis. Use when the user wants to reverse engineer, disassemble, analyze, debug, or patch any binary file including ELF, PE, Mach-O, firmware, or shellcode.

Single-file horizontal-swipe HTML deck in the style of Replit Slides's landing-page template gallery. Eight distinct themes (helix, holm, vance, bevel, world-dark, world-mint, atlas, bluehouse) — each a complete visual system (palette + type + accent) captured from replit.com/slides. Pick one theme, do not mix. For pitch decks, board reports, brand memos, campaign reveals — when the user explicitly wants "Replit Slides style".
End-to-end paper reproduction from arxiv URL through smoke runs to replication experiments. Handles missing or partial official code, missing training scripts, missing hyperparameters, and private datasets via similar-public-dataset substitution. Use when the user asks to reproduce, implement, replicate, or re-run a paper from scratch, or pastes an arxiv URL with reproduction intent.
Create, revise, and quality-check source-grounded research presentations from papers, research notes, data, or manuscripts.
