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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so the safety profile is covered without the description. The description adds that the output is role-specific and scoped to a sprint or area, but it does not explain whether the tool merely returns generated text, how it incorporates project_context, or any other behavioral nuance. This is acceptable but not rich.

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 description is a single front-loaded sentence with no filler or repetition. It is appropriately concise for a simple generator tool, although the brevity does leave semantic gaps in other dimensions.

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?

An output schema exists, so return-value details are not required, but the description still fails to explain parameter semantics, usage context relative to sibling tools, or how the inputs are used. With five optional parameters and zero schema descriptions, an agent has too little guidance to invoke the tool correctly in a nuanced scenario.

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 0%, so the description must compensate for the five undocumented parameters. It only hints at 'role' through 'role-specific' and 'sprint or area' through 'sprint', but it says nothing about resources, project_context, or project_description. The agent gains little parameter understanding beyond what the bare property names already imply.

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 a specific verb and resource: 'Create role-specific agent instructions for a project sprint or area.' It identifies a distinct deliverable and scope, which separates it from generic sibling tools like analyze_project or compare_mcps. However, it does not explicitly contrast itself with closely related tools like generate_config_bundle or plan_project_sprints, so it is clear but not maximally differentiated.

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 'for a project sprint or area' loosely implies the context in which the tool is used, but there is no explicit guidance about when to choose this tool over siblings such as plan_project_sprints or recommend_resources_for_sprint. No when-not-to-use conditions or alternative tool recommendations are provided.

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