Running services and background processes in Flox environments. Use for service configuration, network services, logging, database setup, and service debugging.

Containerizing Flox environments with Docker/Podman. Use for creating container images, OCI exports, multi-stage builds, and deployment workflows.

Performs authorized security scanning using static, dynamic, and vulnerability-focused methods. Use when mapping exposed services, profiling application behavior, and identifying known weaknesses for validation.

Create Obsidian Canvas files from text content, supporting both MindMap and freeform layouts. Use this skill when users want to visualize content as an interactive canvas, create mind maps, or organize information spatially in Obsidian format.

Infer gene regulatory networks (GRNs) from gene expression data using scalable algorithms (GRNBoost2, GENIE3). Use when analyzing transcriptomics data (bulk RNA-seq, single-cell RNA-seq) to identify transcription factor-target gene relationships and regulatory interactions. Supports distributed computation for large-scale datasets.

libsupervision - Process supervision system. Supervisor manages process tree inspired by s6-svscan. LongRunner handles persistent processes with restart. OneShot handles single-execution tasks. ProcessState tracks process lifecycle. LogWriter manages process logging. Use for service management, process control, and graceful shutdown handling.

libconfig - Configuration management library. serviceConfig, extensionConfig, and scriptConfig load settings from files and environment variables. Configuration class provides advanced features like namespacing and storage backend loading. Use for service initialization, environment-specific settings, and runtime configuration.

Synthesizes all pipeline handoffs into a single human-readable project brief. Use when user says "generate docs", "create documentation", "document the project", or after validation passes. Do NOT use for deployment (use fabric-deploy) or architecture design (use fabric-design).

Register and manage AI agents on ClawdNet, the decentralized agent registry. Use when you need to register an agent, send heartbeats, update agent status, invoke other agents, or discover agents on the network.

Use when the user gives a short, rough, or one-line idea for an app, tool, script, or feature and wants it built end-to-end without being asked clarifying questions. Triggers - "build me...", "create an app that...", "I want a tool for...", "quick app for...", minimal specs, seed ideas.

Build high-quality collaborative worlds in Doppel. Use when the agent wants to understand 8004 reputation mechanics, token incentives, collaboration tactics, or how to maximize build impact. Covers streaks, theme adherence, and the rep-to-token pipeline.

Frontend development guidelines for React/TypeScript applications. Modern patterns including Suspense, lazy loading, useSuspenseQuery, file organization with features directory, MUI v7 styling, TanStack Router, performance optimization, and TypeScript best practices. Use when creating components, pages, features, fetching data, styling, routing, or working with frontend code.

Root cause analysis and debugging protocols. Use when encountering errors, test failures, unexpected behavior, stack traces, or when code behaves differently than expected.

Use this skill to get documentation for third-party APIs, SDKs or libraries before writing code that uses them to ensure you have the latest, most accurate documentation. This is a better way to find documentation than doing web search. This includes when a user asks for tasks like "use the OpenAI API", "call the Stripe API", "use the Anthropic SDK", "query Pinecone", or any other time the user asks you to write code against an external service and you need current API reference. Fetch the docs with chub before answering, rather than relying on your pre-trained knowledge, which may be outdated because of recent changes to these APIs. Be sure to use this skill when the user asks for the latest docs, latest API behavior, or explicitly mentions chub or Context Hub. Ensure `chub` is available, run `chub --help`, then follow the instructions there.

When the user needs to create SOPs, playbooks, runbooks, or other operational documentation that defines how a recurring process should be executed.

When a founder needs to write cold emails or LinkedIn messages to prospects, partners, or investors. Activate when the user mentions cold email, outbound, prospecting, LinkedIn outreach, or needs help getting replies from people who don't know them.

When the user wants to create, review, or restructure a fundraising pitch deck for seed or Series A. Also activates when the user mentions "deck", "pitch", "investor presentation", or "slide structure".
