The Agent Skills Directory

[COMMAND_EXECUTION]: The skill uses the Bash tool to perform directory management (mkdir) and execute a local validation script (validate.sh). These operations are necessary for its primary purpose of creating and verifying new skill files within the standard ~/.claude/skills/ path. Variables are properly quoted in the provided shell script to mitigate command injection risks.
[DATA_EXPOSURE]: The skill interacts with the local filesystem to read and write markdown files. It does not access sensitive system directories (like .ssh or .aws) and does not contain any network-enabled tools or logic to exfiltrate data.
[PROMPT_INJECTION]: The skill documentation (AGENTS.md) contains safety-oriented guidelines that instruct the agent to avoid vague guidance and to implement pre-flight environment checks, which reduces the risk of creating malfunctioning or exploitable skills in the future.
[SAFE]: The skill structure uses a clear L1/L2/L3 information architecture, ensuring that heavy reference files are only loaded on demand, which optimizes the context window and minimizes the chance of instruction confusion.
