Agent readability score

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

Agent readability score

Tools are well-documented but have ambiguous parameter types and overlapping functions.based on measured tool list

Strengths

Detailed descriptions explain usage scenarios and constraints clearly.
Clear separation of tools for SMS, voice, contact management, and reporting.

Weaknesses

Some parameter types are unclear (e.g., 'null' type for 'to' in send_sms).
Ambiguous tool names like 'list_blacklist' lack explicit intent clarity.
Overlapping functions between list_messages and get_message may confuse agents.

send_sms — Parameter 'to' has type 'null' with no clarification on expected format.
list_blacklist — Tool name does not explicitly indicate its purpose for blocking numbers.
list_messages — Overlaps with get_message, risking confusion in message retrieval workflows.

Verdict

The toolset is comprehensive with clear documentation, but parameter ambiguity and functional overlaps reduce usability for agents. Strengthening type definitions and clarifying tool intent would improve the score.

2026-09-12T15:21:42.024Z — era changed from 'auth-gated' to 'legacy' · indicates configuration rollback or policy shift
2026-09-14T14:41:53.703Z — complianceScore rose from null to 100 · suggests successful policy implementation or automated check completion

Advice

Monitor complianceScore trends for consistency. Verify if 'legacy' era configuration aligns with current security requirements.
