The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill documents the installation of official development tools such as wac-cli and wasmtime-cli via cargo install, and the retrieval of WIT interfaces using the wkg tool. These tools are maintained by well-known organizations within the WebAssembly community.
[COMMAND_EXECUTION]: The documentation describes the use of the wash CLI tool for building WebAssembly components. It explains that wash build can trigger custom build sequences (e.g., make build) as defined in the project's .wash/config.yaml file, which is the standard expected behavior for this developer tool.
[INDIRECT_PROMPT_INJECTION]: The skill provides architectural patterns and code examples for components that process data from network sockets (wasi:sockets), HTTP requests (wasi:http), and the file system (wasi:filesystem).
Ingestion points: Technical implementation for reading from files (e.g., /data/file.bin) and handling incoming HTTP/TCP data is documented in testing-debugging-performance.md and async.md.
Boundary markers: The code snippets focus on system-level implementation and do not include high-level prompt boundary markers.
Capability inventory: The documented component capabilities include network access, file system interaction, and build-time command execution.
Sanitization: The guide emphasizes correct data type mapping and UTF-8 handling but does not specifically detail sanitization for data intended for LLM consumption.
