Generate artistic infographics from any topic. Runs the Sumi pipeline (analyze → structure → craft prompt → generate image) entirely within Claude Code. Use when "generate infographic", "create infographic", "sumi", "make an infographic about", or "visualize topic".

libtype - Shared Protocol Buffer types. Generated from proto/ definitions. Namespaces include common, agent, memory, graph, vector, tool, trace, llm, resource. Use Type.fromObject() for creation. identifier() method generates resource IDs. Use for typed message creation, protobuf data structures, and cross-service type sharing.

libtelemetry - OpenTelemetry-based logging and tracing. createLogger and Logger provide RFC 5424 structured logging. Tracer creates distributed trace spans. TraceVisualizer renders trace diagrams. TraceIndex stores trace data. observe function wraps operations with timing. Use for logging, distributed tracing, and performance monitoring.

libdoc - Documentation build and serve tools. build function generates static sites from Markdown with Mustache templates. serve function provides local development server. parseFrontMatter extracts YAML metadata from markdown files. Use for generating documentation websites and serving docs locally.

libcodegen - Protocol Buffer code generation. TypeGenerator, ServiceGenerator, and DefinitionGenerator transform .proto files into JavaScript types, gRPC service stubs, and type definitions. Use for generating code from protobuf schemas, automating service stub creation, and maintaining type consistency across services.

Three parallel reviewer agents find contradictions, config gaps, and coverage holes across a project's docs, config, and tests — then fix what you approve. Heavyweight (dispatches parallel agents, can modify files); explicit invocation only. Triggers: /adversarial-review, "adversarial review", "find gaps in my docs/config".

Control LaunchDarkly feature flag targeting including toggling flags on/off, percentage rollouts, targeting rules, individual targets, and copying flag configurations between environments. Use when the user wants to change who sees a flag, roll out to a percentage, add targeting rules, or promote config between environments.

Safely remove a feature flag from code while preserving production behavior. Use when the user wants to remove a flag from code, delete flag references, or create a PR that hardcodes the winning variation after a rollout is complete.

Generate or update ARCHITECTURE.md — a living map of a project's structure, dependencies, and high-coupling zones. Polyglot-adaptive. Heavyweight (writes ARCHITECTURE.md, dispatches parallel agents); explicit invocation only. Triggers: /map, "generate ARCHITECTURE.md", "map this codebase".

Build a throwaway prototype to flush out a design before committing. Routes between two branches — a runnable terminal app for state/business-logic questions, or several radically different UI variations toggleable from one route. Use when the user wants to prototype, sanity-check a data model or state machine, mock up a UI, explore design options, or says "prototype this", "let me play with it", "try a few designs".

Rank functions by CRAP score (complexity × lack of real test coverage) on the current branch, then propose either a refactor or missing tests for the worst offender. Use when the user runs /crap or asks to find risky, complex, poorly-tested code.

Promote Doppel world builds across social platforms. Use when the agent wants to share builds on Twitter/X, Farcaster, Telegram, or Moltbook to drive observers, grow reputation, and recruit collaborators.

Official Rails documentation. Use when asked about any Rails-specific topic including ActiveRecord, routing, controllers, views, mailers, jobs, Action Cable, Action Text, Active Storage, migrations, validations, callbacks, associations, caching, security, or internals.

Use when upgrading a Rails application from one version to another, assessing upgrade readiness, planning a multi-hop upgrade path, or investigating breaking changes, deprecation warnings, gem compatibility issues, or config.load_defaults transitions between any Rails versions from 5.2 through the latest release.

enforces engineering-governance checks before code changes that may be unnecessary, risky, architectural, or scope-widening. use when the user asks whether to refactor, clean up, redesign, choose a next development step, review a proposed implementation, evaluate architectural consistency, review a pull request, or prevent development drift. do not use as the primary implementation skill for routine debugging, bug fixes, feature coding, or language-specific coding unless a no-op, minimal-diff, or architecture-conflict judgment is needed.

Update repo documentation and durable agent-facing artifacts such as AGENTS.md, README.md, docs/, specs, plans, decisions, and runbooks. Use when code, skill, or infrastructure changes risk doc drift or when documentation needs cleanup or restructuring. Do not use for code review, runtime verification, or boot/readiness infrastructure setup.

Style and render geographic data with renderers, symbols, and visual variables. Use for creating thematic maps, heatmaps, class breaks, unique values, labels, and 3D visualization.

Azure AI Content Understanding SDK for Python. Use for multimodal content extraction from documents, images, audio, and video.

Analyzes UEFI bootkit persistence mechanisms including firmware implants in SPI flash, EFI System Partition (ESP) modifications, Secure Boot bypass techniques, and UEFI variable manipulation. Covers detection of known bootkit families (BlackLotus, LoJax, MosaicRegressor, MoonBounce, CosmicStrand), ESP partition forensic inspection, chipsec-based firmware integrity verification, and Secure Boot configuration auditing. Activates for requests involving UEFI malware analysis, firmware persistence investigation, boot chain integrity verification, or Secure Boot bypass detection.
