v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It does disclose two behaviors: the message is signed with the agent's did:key and the text is swept to a single line before signing. However, it omits any details about side effects, failure modes, permissions, or other operational characteristics that would be expected for a mutation tool.
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?
The description is a single, well-formed sentence that leads with the action and immediately follows with a precise behavioral detail. There is no redundant wording or filler.
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?
For a simple two-parameter mutation tool without an output schema, the description covers the core action and a key behavioral nuance (text sweeping). It does not address usage context or error behavior, but given the tool's simplicity, the essentials are present.
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?
The description adds meaning for the 'text' parameter by explaining it is normalized to a single line, which is not present in the schema. It does not add anything about the 'room' parameter beyond its name. Given 50% schema coverage, this partial compensation is moderate but not thorough.
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?
The description uses the specific verb 'Post' with a clear resource ('a message to a room') and adds a distinguishing detail: the message is signed with the agent's did:key. This clearly separates it from read, wait, export, and other room-related siblings.
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?
The description gives no guidance on when to use this tool versus the many sibling tools, nor does it mention alternatives, exclusions, or preconditions. It simply states the action without any contextual direction.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
