The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill recommends the installation of several well-known and reputable packages including @tsconfig/strictest, @total-typescript/ts-reset, zod, and type-fest. These are standard tools in the TypeScript ecosystem for enforcing strict typing and improving development workflows.
[INDIRECT_PROMPT_INJECTION]: As the skill is designed to process and review user-provided TypeScript code, it naturally possesses an indirect prompt injection surface.
Ingestion points: Triggered by user requests to "review", "check", or "write" TypeScript code, as well as modifications to .ts and .tsx files.
Boundary markers: The skill does not define specific delimiters for separating user-provided code from the agent's instructional context.
Capability inventory: The skill provides logic for code generation and review; it does not request specific shell execution or network capabilities beyond standard agent tools.
Sanitization: No specific input sanitization is defined within the skill instructions.
[NO_CODE]: The skill consists entirely of markdown-based instructions and configuration references. It does not include any executable scripts, binaries, or automation code that would run on the host system.
