Claude Code’s 32k-token prompt is why some developers prefer a 1k-token harness

- The author is frustrated that Claude Code’s system prompt has grown to 32k tokens, which hurts cost, latency, and performance.
- They prefer a bare-bones coding-agent harness like Pi: just four tools (read, write, edit, bash) plus the agent loop.
- The argument is that features such as permissions, MCP clients, and subagents should not keep bloating the core prompt; instead, extra functionality should be added through plugins.
- The post notes that Claude Code and Codex have both recently reduced their system prompts by roughly 60%, but argues the broader architectural problem remains.
- Overall, it’s a practical discussion of how to keep agent setups controllable as feature sets expand.
