What CLI Discovery does

CLI Discovery checks the host system to identify installed command-line tools, their versions, and authentication status for common CLIs like gh, aws, and gcloud. Use it when you need to know what's available before scripting or agent tasks.

CLI Discovery is cataloged under DevOps on DirSkills. CLI Discovery comes from a repository tagged agent, agentic-ai, ai-assistant, anthropic and autonomous-agents.

Excerpt

CLI Discovery

When you need to discover what CLI tools are available on the system, use host_bash to check directly. Do not use sandboxed bash for discovery - it may not see host-installed CLIs or auth state, leading to false negatives.

Checking if a CLI exists

which <name>        # returns path if found, exits non-zero if missing
command -v <name>   # alternative, works in all POSIX shells

This is the opening of the README. Read the full README on GitHub.
