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

With no annotations, the description carries the full safety burden, and it does disclose the data sources (web console and MCP callers) and the decision vocabulary returned. However, it never states that the operation is read-only, how results are ordered/paginated beyond 'most recent', or whether the demo data is ephemeral, which matters for an agent deciding how much to trust the output.

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 sentences, zero filler, with the resource and its scope front-loaded before the use-case hint. Every clause earns its place.

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 one-optional-param list tool with no output schema, the description conveys the source and the nature of returned records well enough to call it correctly. It could go slightly further on ordering (newest-first?) and result shape, but nothing critical is missing.

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 coverage is 100% and the single 'limit' parameter is fully documented in the schema (default 10, max 20), so the schema does the heavy lifting. The description adds nothing about the limit or its bounds; baseline 3 applies.

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 verb+resource ('List the most recent payment authorization decisions') and scopes it to the public demo, which cleanly separates it from the single-lookup get_authorization and the write-side authorize_payment. It stops short of naming those siblings, so differentiation is implicit rather than explicit.

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?

'Useful to see recent ALLOW/DENY/REQUIRE_APPROVAL activity' hints at the use case but gives no explicit when-to-use vs. when-to-use-something-else guidance and names no alternative. Usage is implied rather than stated.

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