mesh_balance

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description implies a read-only operation by mentioning 'balance' and 'activity', but it does not explicitly state that no data is modified, nor does it mention authentication or rate limits. In the absence of annotations, the description carries the full burden, but it provides minimal behavioral context.

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 extremely concise, consisting of a single sentence with no unnecessary words. It is front-loaded and efficient, earning its place without fluff.

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?

Given no output schema, the description should explain return values more thoroughly. It mentions 'balance and recent activity' but provides no detail about format, fields, or pagination. For a simple read tool, it is minimally adequate but could be improved.

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?

With zero parameters, schema coverage is 100% vacuously. The description adds no parameter information because there are none, so the baseline score of 4 is appropriate.

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 clearly identifies the resource (MESH credit balance) and the action (viewing recent activity). It distinguishes well from sibling tools like mesh_signup or mesh_publish, which have different purposes. However, 'recent activity' is somewhat vague, leaving room for interpretation about what exactly is returned.

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 guidance is provided on when to use this tool versus alternatives. For example, it does not mention checking balance before making a transaction or how it relates to other mesh tools. The description simply states what it does, without context or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
