Plugin runtimes (openclaw, hermes, paperclip) wrap external CLIs and may not
propagate JS customTools to the underlying agent, so fn_identity could be
unreachable on those runtimes. Embedding the agent's identity (role, soul,
instructions, memory previews) directly in every execution prompt guarantees
the agent always sees what loaded for the tick — fn_identity remains as an
optional richer read for runtimes that do support custom tools.
