Diagnoses and fixes conflicts between Tailscale and proxy/VPN tools (Shadowrocket, Clash, Surge) on macOS. Covers five conflict layers - (1) route hijacking, (2) HTTP proxy env var interception, (3) system proxy bypass, (4) SSH ProxyCommand double tunneling, and (5) VM/container runtime proxy propagation (OrbStack/Docker). Includes SOP for remote development via SSH tunnels with proxy-safe Makefile patterns. Use when Tailscale ping works but SSH/HTTP times out, when browser returns 503 but curl works, when git push fails with "failed to begin relaying via HTTP", when Docker pull times out behind TUN/VPN, when setting up Tailscale SSH to WSL instances, or when bootstrapping remote dev environments over Tailscale.

Create PDF documents from markdown with proper Chinese font support using weasyprint. This skill should be used when converting markdown to PDF, generating formal documents (legal, trademark filings, reports), or when Chinese typography is required. Triggers include "convert to PDF", "generate PDF", "markdown to PDF", or any request for creating printable documents.

Comprehensive healthcare AI toolkit for developing, testing, and deploying machine learning models with clinical data. This skill should be used when working with electronic health records (EHR), clinical prediction tasks (mortality, readmission, drug recommendation), medical coding systems (ICD, NDC, ATC), physiological signals (EEG, ECG), healthcare datasets (MIMIC-III/IV, eICU, OMOP), or implementing deep learning models for healthcare applications (RETAIN, SafeDrug, Transformer, GNN).

Convert or migrate Azure ARM (Azure Resource Manager) templates, Bicep templates, or code to Pulumi, including importing existing Azure resources. This skill MUST be loaded whenever a user requests migration, conversion, or import of ARM templates, Bicep templates, ARM code, Bicep code, or Azure resources to Pulumi.

Configures and runs Depot remote container builds using `depot build` and `depot bake`. Use when building Docker images, creating Dockerfiles with Depot, pushing images to registries, building multi-platform/multi-arch images (linux/amd64, linux/arm64), debugging container build failures, optimizing Dockerfile layer caching, using docker-bake.hcl or docker-compose builds, or migrating from `docker build` / `docker buildx build` to Depot. Also use when the user mentions depot build, depot bake, container builds, image builds, or asks about Depot's build cache, build parallelism, or ephemeral registry.

Set up and manage Descope projects with Terraform. Use when configuring authentication infrastructure as code, managing environments, creating roles/permissions, setting up connectors, or deploying Descope project configurations.

librepl - Interactive REPL utilities. Repl class creates command-line interfaces with custom commands, state persistence, and terminal formatting. Supports dependency injection for testability. Use for building CLI tools, interactive debugging interfaces, and developer utilities.

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.
