I Keep Forgetting CLIs So Does My AI Agent - Simplifying CLI Usage for Human and AI Agents with Hints and Completion

The author built agtm (agent manager/marketplace), a CLI helper tool with hints and auto-completion that helps both humans and AI agents discover and run CLI commands without memorizing them. It uses a local RAG (trie) to match skill IDs and suggest relevant CLI commands, supporting both interactive and agent modes for tools like playwright-cli, claude, and codex.
