All you actually need is 50 lines and one tool.

If your agent can execute Bash commands, it can do anything, including reading files (with cat), writing them (with sed / patch / awk /perl), grepping, finding, and everything else you may possibly need. The specialized tools are just an optimization to make things easier for the agent. They do increase performance (in the "how much can this do", not the "how fast is this" sense), but they're not strictly required.

IMHO, this is one of the more significant LLM-related discoveries of 2025. You don't need a context-polluting Github MCP that takes 10+% of your precious context window, all you need is the gh cli, which the agent already knows how to use.
