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

Annotations already declare readOnlyHint=true, destructiveHint=false, and a closed-world scope, so the safety profile is fully covered by structured data. The description adds the useful behavioral nuance that generation status is included in the response, but says nothing about pagination, freshness, or error behavior on a missing/invalid project.

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?

A single front-loaded sentence with no filler; the tool's action and the two things it returns are communicated immediately. Nothing here is redundant with the title.

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 one-parameter read tool this covers the essentials, and the mention of 'details and latest generation status' partially compensates for the absent output schema. It stops short of clarifying return shape or the relationship to sibling tools, so it is adequate but not complete.

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% and the description never mentions projectId, its format, or where it comes from. The parameter is reasonably self-evident by name, but the description contributes no semantics beyond the raw schema.

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 specific verb and resource ('Get a life-story project's details') and adds a scoping detail ('latest generation status') that tells the agent what subset of data matters. It does not explicitly distinguish itself from siblings like list_life_projects or get_story, but the singular 'project's details' makes the single-project scope inferable from the name.

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 or when-not-to-use guidance and no named alternative (e.g., list_life_projects for browsing, get_story for story content). Usage is only implied by the tool name and the required projectId, which is the minimum viable level.

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