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

Annotations already declare readOnlyHint=true, idempotentHint=true and openWorldHint=false, so the safety profile is covered. The description adds nothing beyond that — no pagination behavior, no result limits, no statement of what the list contains or whether it is filtered/ordered.

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?

One short sentence that is front-loaded and free of padding, which is structurally clean. But the brevity reflects under-specification rather than disciplined conciseness, so it does not rise above a minimum-viable mark.

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 values need not be explained. Still, for a tool in a dense sibling set containing stories_get, stories_get_many and requirements_list, the description omits any routing or scoping context an agent needs to select it correctly.

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 the single project_id parameter is fully documented in the schema as a project UUID. The description's phrase 'for a project' merely restates the schema rather than adding format or constraint detail, so the baseline of 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 states a clear verb+resource ('List stories') and scopes it to a project, so the basic operation is unambiguous. However, it offers no differentiation from siblings such as stories_get_many, which also returns multiple stories, leaving the agent to guess which is appropriate.

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 when-to-use guidance, no mention of alternatives (e.g., stories_get_many for ID-based retrieval), and no prerequisites or exclusions. The only usage signal is the implicit project scoping carried by the required parameter.

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