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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false and destructiveHint=false, so the safety profile is covered. The description adds only that the output is a prioritize/plan/deprioritize verdict; it says nothing about scoring mechanics, tie-breaking, or the score shape despite there being no output schema.

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 functional sentence is front-loaded and dense, but the trailing promotional URL ('See the full version at https://...') does not help an agent decide or invoke anything and dilutes the definition.

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?

With five required enum parameters fully documented in the schema, the main remaining burden is the missing output schema, and the description at least communicates the verdict categories the score maps to. That covers most of what an agent needs, though the numeric score range and any thresholds remain unspecified.

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 description coverage is 100% and each parameter carries an enum plus an explicit weight (30/20/20/15/15), so the schema does the heavy lifting. The description lists the same five dimensions but adds no interpretation beyond the schema, which is the baseline case.

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 clear verb ('Score') and resource ('a candidate international market') and enumerates the five scoring dimensions, so the agent knows exactly what the tool computes. It does not differentiate itself from near-neighbors like growth_strategy_prioritization_tool or total_addressable_market_estimator, which keeps it short of a 5.

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 phrase 'to decide whether to prioritize, plan, or deprioritize it' implies the decision context in which the tool is useful, which is better than nothing. However, there is no explicit when-to-use vs. when-not guidance and no named alternative for adjacent market/strategy scoring tasks.

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