The deciding difference is operational: Prime Agent can run on infrastructure you control, Claude Code cannot. If that constraint is real for you, it settles the choice before anything else is considered.
Anthropic's coding agent — terminal, IDE and SDK, with hooks, skills and MCP built in.
Configure via .claude/settings.json; drop reusable procedures in .claude/skills/.
Prime Intellect's recursive-language-model harness — a persistent IPython kernel is the only tool, sub-agents are function calls.
Drops fixed tool schemas and context compaction: the agent writes programs over its own context, and can CRUD its own prompts, skills and sub-agents mid-run.
