The Agent Skills Directory

[COMMAND_EXECUTION]: The skill utilizes the vendor-provided a4 CLI and the standard Rust cargo toolchain to perform various tasks.
Evidence: Commands such as a4 idl summary, a4 idl relations, a4 config validate, cargo check, and cargo build are used to inspect data and compile artifacts.
[DYNAMIC_EXECUTION]: The skill involves generating and compiling code based on external definitions using Rust macros.
Evidence: The instructions specify that the "DSL is compiled by Rust macros" and that cargo build should be used to generate content-addressed artifacts under the .arete/ directory.
[INDIRECT_PROMPT_INJECTION]: The skill processes external Solana program Interface Definition Language (IDL) files, which serves as an ingestion point for untrusted data.
Ingestion points: idl/<program>.json files are consumed by the a4 CLI and the #[arete(idl = [...])] Rust macro.
Boundary markers: The skill encourages the use of machine-readable IDL analysis and local artifact validation (a4 config validate) before further use.
Capability inventory: The skill performs local file writes to .arete/ and executes local build commands (cargo build).
Sanitization: Users are instructed to verify instruction account names independently and document cross-account update routes against the IDL.
