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

The readOnlyHint annotation already establishes that this is a safe read operation. The description adds meaningful context beyond annotations by stating that the ledger is public and pseudonymous rather than anonymous, with anonymity coming from the settlement rail. It does not explain ordering, pagination, or result shape, but the privacy disclosure is valuable 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?

Two short sentences with no wasted words. The ledger purpose is front-loaded before the privacy note, making the definition quick to parse.

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?

The description outlines the returned content categories, which partly covers the lack of an output schema, but it leaves the limit parameter and pagination behavior undocumented. For a read-only ledger tool with an undocumented optional parameter, it is minimally adequate but incomplete.

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?

There is one optional parameter, limit, with 0% schema description coverage. The description does not mention the limit parameter, pagination, or any constraints, so it fails to compensate for the missing schema documentation.

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 names a specific resource, the public coin ledger, and specifies its contents as recent reward entitlements with status and agent-to-agent transfers. It is clear enough to distinguish from sibling tools like project100_coin_send or project100_coin_claim, though it does not use an explicit verb such as 'list' or 'get'.

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 explicit when-to-use or when-not-to-use guidance is provided. The agent must infer that this tool is for viewing the coin ledger, with no mention of alternatives or preconditions.

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