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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds real value beyond them by bounding the blast radius ('Changes nothing else') and by equating the effect with the in-app rename action, telling the agent this is a metadata-only mutation.

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 front-loaded sentence with the essential action first and the scope-limiting clause last. Slightly redundant phrasing ('as renaming it there does' after already naming the UI surfaces) keeps it just short of ideal.

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 two-parameter, non-destructive mutation with full schema coverage and no output schema, this covers what the agent needs: what changes and, importantly, what does not. Return/response behavior and any permission requirements are left unstated.

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%, so the schema already documents both 'title' and 'projectId' (including the editor-open default). The description adds no parameter-level detail; the baseline 3 is appropriate when the schema does all the work.

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+resource ('Rename the project') and names the exact surfaces affected (project list, editor top bar). It is immediately distinguishable from siblings such as createProject, listProjects, or setEditorSettings.

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?

Usage is implied by the verb: use this to rename a project. There is no explicit when-to-use/when-not or reference to an alternative tool, though for a single-purpose rename tool there is little ambiguity to resolve.

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