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

Annotations already establish readOnly, idempotent and non-destructive; the description adds real value by stating what each option exposes (status, evidence still needed) and drawing explicit outcome boundaries (no eligibility verification, no payable price, no savings, no refund approval, no filing authorization). This is exactly the behavioral context annotations cannot express, though return shape is not described.

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 are front-loaded with the browse purpose, and the disclaimer is compact and purposeful rather than filler. The disclaimer list is somewhat long but each item earns its place by fencing off non-capabilities.

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 no-param, no-output-schema read-only browse tool, the description adequately covers both what the catalog shows and what it guarantees not to do. Nothing essential to calling it correctly is missing, though the absence of an output schema means a sentence on result structure would have completed it.

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 the baseline of 4 applies; there is nothing for the description to clarify semantically.

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?

'Browse' gives a concrete verb and the resource is spelled out as property-tax research options plus the connection's available tools. It is clearly a discovery/catalog tool rather than an executor, though the name ('microtransactions_catalog') is slightly misaligned with the 'property-tax research options' phrasing and no sibling is explicitly contrasted.

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 closing disclaimer implicitly tells the agent this is informational only and that actual verification/pricing/filing belongs to other tools, which is genuine routing guidance. However, it never names an alternative sibling (e.g., audit_microtransaction, start_tax_sandbox) or states a positive 'use this when' condition, leaving usage largely inferred.

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