Does the description explain when to use this tool, when not to, or what alternatives exist?
Usage is only implied: the mention of education and cross-company progression hints this is the synthesized narrative view rather than a raw list, but there is no explicit 'use this instead of get_experience/get_education when...' guidance and no exclusions. An agent facing four overlapping siblings (get_contact, get_education, get_experience, list_experience) gets no routing rule.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
