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

No annotations are provided, so the description carries the full burden. It helpfully discloses the exact metric families returned (views, unlocks, revenue composition, protocol fees), which is real behavioral context, but says nothing about read-only nature, auth requirements, data freshness, or caching.

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?

One front-loaded sentence that leads with the resource and then enumerates fields. The list is long but each item is a distinct metric, so it earns its space; no filler or redundancy.

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 read-only, no-argument aggregate tool with no output schema, enumerating the returned metrics is the key information an agent needs, and it is present. Missing only secondary context like refresh cadence or auth, which is minor here.

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 tool takes zero parameters, so there is nothing to describe and the schema cannot be missing anything. Baseline for a 0-param tool.

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 ('Get') and resource ('platform-wide Nibgate totals') and enumerates the metric families returned, so an agent knows exactly what this surfaces. It does not explicitly contrast itself with siblings like get_leaderboards or get_ledger, but the 'platform-wide totals' framing is distinct enough to be usable.

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 never states when to reach for this tool versus the sibling stats/ledger/leaderboard tools, nor any prerequisites. Usage is only weakly implied by the name and the word 'totals'.

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