The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill provides instructions to install the CUE CLI using go install cuelang.org/go/cmd/cue@latest. This targets the official domain for the CUE project.
[COMMAND_EXECUTION]: The documentation includes several shell command examples for managing configuration, such as cue eval, cue export, and cue vet. Additionally, a Julia code snippet demonstrates executing the cue binary as a subprocess via backticks to capture output.
[INDIRECT_PROMPT_INJECTION]: The skill documents an attack surface for indirect prompt injection as it is designed to process external data files.
Ingestion points: Reads and validates data.yaml, schema.cue, and config.cue (SKILL.md).
Boundary markers: None present in the instructional examples.
Capability inventory: The skill uses the cue CLI for evaluation and export; the Julia bridge utilizes subprocess execution to read CUE data.
Sanitization: CUE is explicitly designed to be non-Turing complete, which provides inherent protection against termination issues and side effects during data evaluation.
