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

Annotations already declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false, and the description's 'Read-only' merely restates that. It does add useful value by disclosing the shape of the returned data (ranked Opportunity Map buckets, monthly value in org currency, recommended Blueprint, status, and estimated vs measured values), which matters since no output schema exists.

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 main sentence is dense but front-loads the two headline outputs (readiness score, Opportunity Map) and stays compact. The trailing 'Read-only' is redundant with the annotations and is the only sentence that fails to earn 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?

With no output schema, the description carries the burden of describing return content and it does so adequately: readiness score, ranked buckets, monthly value, blueprint, status, and estimated vs measured. Minor gaps remain (what status values exist, whether the map is org-wide or filtered), but nothing blocks correct invocation.

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 for the description to disambiguate. Baseline 4 applies for a no-argument 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?

The description states the specific resource being retrieved (the organization's readiness score and ranked Opportunity Map) and enumerates its contents, so an agent knows this is a strategy-summary read rather than an agent/blueprint/catalog read. It stops short of naming sibling tools, but the resource is distinctive enough to be recognizable.

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?

There is no explicit when-to-use guidance, no prerequisites, and no reference to alternatives such as get_performance, list_goals, or get_blueprint. The 'Read-only' tag implies it is a safe inspection call, but nothing tells the agent when this is the right tool versus its siblings.

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