The Agent Skills Directory

[COMMAND_EXECUTION]: The skill utilizes mkdir for directory management and git worktree for prototyping branches. These are standard development operations consistent with the skill's stated purpose.
[PROMPT_INJECTION]: The skill processes untrusted data from the codebase and user input, creating a surface for indirect prompt injection. Ingestion points: User feature descriptions and existing codebase analysis in SKILL.md. Boundary markers: Absent; the skill does not use specific delimiters to isolate untrusted data. Capability inventory: File system access and command execution via mkdir and git worktree in SKILL.md. Sanitization: Absent. Mitigation: The workflow includes mandatory human-approval checkpoints at every phase (Context, Prototyping, Requirements, Design, Plan, Implementation), which effectively mitigates the risk of the agent autonomously following malicious instructions embedded in the data it processes.
