v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It does disclose one genuinely useful behavioral trait: the recipient's reply is remote data and should be treated as untrusted. However, it omits delivery semantics (synchronous vs queued), whether it blocks on a reply, and any rate-limit or auth context for what is effectively a write/transmit operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two tightly written sentences, front-loaded with the action and followed by the safety caveat. Nothing extraneous.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
An output schema exists, so return values need not be explained. But with zero annotations and zero parameter coverage, the description leaves delivery behavior and argument meaning undocumented, which is a meaningful gap for a transmit operation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate for the two undocumented parameters and does not. 'recipient' loosely maps to target_agent_id and 'message' to text, but no format, ID scheme, or length/type constraints are conveyed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
States a specific verb and resource ('Send a direct agent-to-agent message') plus the transport ('over the AGORA relay'). The word 'direct' hints at the distinction from agora_post_message, but it never names or contrasts that sibling explicitly.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No statement of when to use this versus agora_post_message, agora_forum message tools, or the a2a_registry/card siblings. The agent must infer usage from the tool name alone; there are no exclusions or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
