The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill provides instructions for the agent to install the d2 diagramming tool from well-known sources such as nix shell nixpkgs#d2 or go install oss.terrastruct.com/d2@latest if the command is missing.
[COMMAND_EXECUTION]: The skill uses shell commands to carry out its primary purpose, specifically executing the d2 binary to render diagrams, using date for filename generation, and command -v for tool discovery.
[INDIRECT_PROMPT_INJECTION]: The skill's functionality involves researching the codebase and interpreting its structure, which represents a surface for indirect prompt injection from untrusted source data.
Ingestion points: Codebase research and dependency identification (SKILL.md, Process Step 1).
Boundary markers: None identified.
Capability inventory: Execution of d2 and date binaries via shell commands, and file writing capabilities within the docs/ directory tree.
Sanitization: The skill does not explicitly describe any sanitization of codebase data before it is incorporated into visual diagrams.
