Catalog
Every x402, MPP, MCP, and skill listing we've indexed, normalized, and enriched.
vault
Encrypted secrets vault for AI coding agents. Store API keys, passwords, and tokens with `age` (public-key encryption) and `sops` (encrypted YAML secrets files). Never plaintext.
trueskill-rank
Domain-agnostic TrueSkill batch ranking via LLM-as-judge. Ranks any list of text items using overlapping subsets dispatched to Codex Spark workers. Swappable rubrics. Use when you need to rank, score, curate, or sort a collection by quality.
summarize
Content extraction skill for AI coding agents. YouTube transcripts, podcasts, PDFs, images (OCR), audio/video via the summarize CLI.
peekaboo
Native macOS GUI automation via peekaboo 3.0+. AX-first hybrid with VLM fallback, FSM-based workflows with bug-specific transitions. Safari web automation, native app control, social media operations, system dialogs, cross-app workflows.
image-gen
Image generation, editing, and review via OpenRouter API. Five models from budget to premium. Style presets for series consistency, JSON structured prompts, reference image anchoring, system message support, prompt upsampling. Vision-based quality review loop. Zero dependencies b
gsd-coordinator
End-to-end task orchestration across AI coding engines. Coordinates Claude, Codex, Codex Spark (the faster Codex variant), and OpenCode workers using dispatch-verify-synthesize workflows. Requires the upstream agent-mux CLI for worker dispatch. Use when work spans multiple depend
google-workspace-ops
Google Workspace CLI automation via gogcli. Gmail, Calendar, Drive, Docs, Slides, Sheets, and 9 more services. JSON-first output, composable pipelines.
chatgpt-search
Search ChatGPT conversation exports using SQLite FTS5 (SQLite full-text search). BM25-ranked full-text search (relevance scoring) with TF-IDF keywords (term-weighted key phrases), date/role/model/language filtering, and conversation browsing. Use when agent needs to search past C
browser-ops
Browser automation skill for AI coding agents. 25 Playwright-based tools for navigation, interaction, observation, and session management.
arxivterminal
CLI tool (arxivterminal) for fetching, searching, and managing arXiv papers locally. Use when working with arXiv papers using the arxivterminal command - fetching new papers by category, searching the local database, viewing papers from specific dates, or managing the local paper
arxiv-lookup
Look up arXiv paper metadata via the arXiv API. Use when you need to get a journal DOI from an arXiv ID (for OpenAlex integration), or find an arXiv ID from a title/keyword search (for arxiv-doc-builder). Requires the `arxiv` Python package.
arxiv-doc-builder
Convert arXiv papers to Markdown documentation. Fetches available materials from arXiv (LaTeX source when available + PDF), converts LaTeX to Markdown via pandoc (happy path). PDF-only papers get a naive single-column fallback — use the specialized PDF scripts for better results.
philosophy
Suckless philosophy and manifest for building simple, minimal, maintainable software with a focus on clarity and frugality.
coding-style
Coding style guidelines for C and POSIX code, covering layout, formatting, declarations, headers, and consistency expectations.
bitreich-manifesto
Bitreich manifesto and principles for simple, reusable, maintainable software, command-line interfaces, patch-driven collaboration, and programmer-oriented tools.
refactoring-ui
Comprehensive UI design guidance based on Refactoring UI principles covering visual hierarchy, color theory, typography, spacing, and mobile-first responsive design. Use this skill whenever the user is creating new pages, building components, making design additions or changes, r
agent-canvas
Draw diagrams, flowcharts, and visualizations on an Excalidraw canvas. Use when the user asks to draw, visualize, create diagrams, or sketch ideas.
inngest-steps
Use when implementing delays that must survive process restarts (e.g., 24-hour cart abandonment, scheduled follow-ups), waiting for human approval or external events with timeouts (review gates, webhook callbacks, async API completion), polling external services without losing st
inngest-setup
Use when adding durable execution to a TypeScript project — building retry-safe webhook handlers, background jobs that survive crashes, scheduled tasks, or long-running workflows that outlive a single request. Covers Inngest SDK installation, client config, environment variables,
inngest-middleware
Use when adding cross-cutting concerns to durable functions — structured logging or tracing across all functions, error tracking with Sentry, payload encryption for sensitive data, dependency injection of clients (DB, Stripe, etc.) into function handlers, custom telemetry, or beh
inngest-flow-control
Use when handling external API rate limits (e.g., OpenAI 429s, HubSpot or Stripe rate limits), preventing duplicate work from rapid event bursts (debouncing user actions), spreading load over time, ensuring per-tenant fairness, processing events in batches, limiting concurrent ru
inngest-events
Use when designing event-driven workflows, decoupling services, implementing fan-out patterns (one trigger, many downstream handlers), implementing idempotent event handling with IDs (24-hour dedupe window), or handling at-least-once delivery from external sources like Stripe web
inngest-durable-functions
Use when building functions that must survive process crashes, retry automatically on failure, run on a schedule, react to events, or maintain state across infrastructure failures — e.g., webhook handlers that drop events, flaky cron jobs, background jobs that fail mid-execution,
nutmeg-wrangle
Transform, filter, reshape, join, and manipulate football data. Use when the user needs to clean data, merge datasets, convert between formats, handle missing values, work with large datasets, or do any data manipulation task on football data.
