member graph compile failed: {e}

Error message

member graph compile failed: {e}

What it means

Compiling the tinyagents member-execution graph failed at builder.compile() — a structural error in the graph definition itself (e.g. a node referenced by an edge was never added, entry/finish not marked, or command routing points at a nonexistent node). This is a programming/config error in the member graph topology, not a runtime failure of the member's work.

Solutions

1. Inspect the graph construction just above (add_node/add_edge/set_entry/set_finish/mark_command_routing) for inconsistencies with the compile error's detail
2. Ensure every edge target ('complete','fail','done') has a corresponding add_node
3. Add a unit test that compiles the member graph so topology regressions fail at build time

When it happens
