A seed agent: the smallest starting point from which an agent can grow. There is no framework here. The entire frozen layer is seed.py — a small loop that connects a language model to exactly one tool ( exec , which runs bash) and loads its system prompt from a file the agent itself owns and may rewrite. Everything an agent normally gets from a framework — tools, memory, skills, conventions — must instead be grown by the agent, session by session, into its self/ directory. Plant one mkdir my-agent && cd my-agent uvx --from git+https://github.com/vivekhaldar/seed.git seed First run copies seed.py and run_seed.sh into this directory (never overwriting a file that already exists), germinates self/SELF.md , and commits those files together in a fresh git repo here — the loop is part of this individual's history, not only self/ . Then it drops you into a REPL. Start talking. Everything the agent wants to keep must be written into self/ — sessions are ephemeral and nothing else survives.…
