Agent readability score

Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.

Agent readability score

Fable 5 Agent tools provide clear async task management with some parameter ambiguity.based on measured tool list

Strengths

Clear tool naming for task lifecycle management
Describes usage order between create/run and status/result
Includes cost constraints and cancellation capabilities

Weaknesses

Parameter requirements are not explicitly documented
Some descriptions could clarify usage scenarios

agentfarm_create_run — Missing parameter specificity
agentfarm_agent_info — Could clarify usage context

Verdict

Tools offer robust async task management with clear naming. The main improvement needed is documenting parameter requirements for precise usage.
