Teaches an agent to compose a workflow with the `workflow_create` tool that LibreFang ships as a builtin: when a workflow beats a one-off `agent_send`, the four agent-binding shapes and why `{"type": …}` find-or-spawn makes a workflow portable, how `required_skills` fails a step before it bills an LLM call, and the creation-time validations an author is most likely to trip.
Written against the tool's implementation rather than its issue description, and the copy pinned in librefang/librefang's registry snapshot is loaded by `crates/librefang-runtime/tests/workflow_creator_skill.rs`, which checks the ceilings quoted here against the live tool schema.
