libgraph - RDF graph index using N3 library. GraphIndex stores and queries linked data triples. PREFIXES provides standard namespaces (schema, rdf, rdfs, foaf). parseTripleQuery parses subject-predicate-object patterns. serializeShacl generates SHACL constraints. Use for knowledge graphs, semantic queries, and linked data processing.

Golang performance optimization patterns and methodology - if X bottleneck, then apply Y. Covers allocation reduction, CPU efficiency, memory layout, GC tuning, pooling, caching, and hot-path optimization. Use when profiling or benchmarks have identified a bottleneck and you need the right optimization pattern to fix it. Also use when performing performance code review to suggest improvements or benchmarks that could help identify quick performance gains. Not for measurement methodology (see golang-benchmark skill) or debugging workflow (see golang-troubleshooting skill).

Comprehensive documentation guide for Golang projects, covering godoc comments, README, CONTRIBUTING, CHANGELOG, Go Playground, Example tests, API docs, and llms.txt. Use when writing or reviewing doc comments, documentation, adding code examples, setting up doc sites, or discussing documentation best practices. Triggers for both libraries and applications/CLIs.

Structured error handling in Golang with samber/oops — error builders, stack traces, error codes, error context, error wrapping, error attributes, user-facing vs developer messages, panic recovery, and logger integration. Apply when using or adopting samber/oops, or when the codebase already imports github.com/samber/oops.

OpenClaw integration for 1ly payments. Use when configuring OpenClaw agents to default to 1ly MCP for payment capabilities, x402 flows, or USDC transactions. Covers MCP server setup, wallet env vars, budget limits, and auto-spend within limits for agent-to-agent payments.

Joel's writing voice and style guide for joelclaw.com content. Use when writing, editing, or reviewing any blog post, essay, book chapter, or prose content for joelclaw.com. Also use when asked to 'write like Joel,' 'match Joel's voice,' 'draft a post,' 'write content for the blog,' or 'review this for voice.' This skill captures Joel's specific writing patterns derived from ~90,000 words of published content spanning 2012–2026. Cross-reference with copy-editing and copywriting skills for marketing-specific copy.

Deploy Dojo worlds to local Katana, testnet, or mainnet. Configure Katana sequencer and manage deployments with sozo. Use when deploying your game or starting local development environment.

Integrate Dojo with game clients for JavaScript, Unity, Unreal, Rust, and other platforms. Generate typed bindings and connection code. Use when connecting frontends or game engines to your Dojo world.

Configure ViewModel state emission with StateFlow, sealed UiState classes, and lifecycle-safe collection in Android. Use when working with ViewModels, UiState patterns, or exposing state to Compose UI.

Generates 3-4 strategic talk angles with strength/weakness analysis, title options, CFP descriptions, and a peer feedback draft, then enforces a mandatory CHECKPOINT for user confirmation before scripting. Use when deciding how to frame a talk, preparing a CFP submission, or choosing between multiple narrative angles.

Builds a numbered, categorized concept catalogue from the talk summary and timeline, scoring each concept HIGH / MEDIUM / LOW for talk potential with optional repo enrichment. Use when you need a structured inventory of concepts before choosing a talk angle, or when assessing which ideas have the strongest presentation potential.

Azure AI Voice Live SDK for .NET. Build real-time voice AI applications with bidirectional WebSocket communication.

Sets up and configures Hookdeck Outpost for outbound event delivery to customer endpoints. Use when sending webhooks to customers, building webhook delivery infrastructure, managing tenants and destinations with supported types (webhooks, Hookdeck Event Gateway, AWS SQS/Kinesis/S3, Azure Service Bus, GCP Pub/Sub, RabbitMQ, Kafka), or aligning topics and publishes. EventBridge support is tracked in GitHub issues.

Find similar vulnerabilities and bugs across codebases using pattern-based analysis. Use when hunting bug variants, building CodeQL/Semgrep queries, analyzing security vulnerabilities, or performing systematic code audits after finding an initial issue.

Interprets Culture Index (CI) surveys, behavioral profiles, and personality assessment data. Supports individual profile interpretation, team composition analysis (gas/brake/glue), burnout detection, profile comparison, hiring profiles, manager coaching, interview transcript analysis for trait prediction, candidate debrief, onboarding planning, and conflict mediation. Accepts extracted JSON or PDF input via OpenCV extraction script.

Best practices for webhook handlers. Use when implementing the handler sequence (verify first, parse second, handle idempotently), idempotency, error handling, retry logic, or framework-specific issues with Express, Next.js, or FastAPI.

Create a minimal working Firecrawl example that scrapes a page to markdown. Use when starting a new Firecrawl integration, testing your setup, or learning the scrape/crawl/map/extract API surface. Trigger with phrases like "firecrawl hello world", "firecrawl example", "firecrawl quick start", "simple firecrawl code".

Implement Exa reliability patterns: query fallback chains, circuit breakers, and graceful degradation. Use when building fault-tolerant Exa integrations, implementing fallback strategies, or adding resilience to production search services. Trigger with phrases like "exa reliability", "exa circuit breaker", "exa fallback", "exa resilience", "exa graceful degradation".
