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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered elsewhere. The description adds workflow context missing from annotations — that MCP approval requirements are administrator-configurable while business workflow approvals always apply — which is useful for anticipating a possible approval gate, but it is org-wide boilerplate with no detail on what a blocked read looks like or what scoping applies to the connected organization.

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 actionable instruction ("Read a project by ID") is buried in the middle, behind a generic tool-selection preamble. The approval sentence is broadly applicable boilerplate that could sit on any tool in this server, diluting the definition of a simple one-parameter read.

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 single-parameter read with an output schema present, full annotations, and a closed-world scope, the description covers what is needed to call it correctly; return-value documentation is not required. The only real gap is the absence of any pointer to list_projects as the alternative for enumeration.

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 coverage is 0%, so the description is the only prose source, and "by ID" only conveys that the single parameter identifies the project. The schema itself supplies the UUID format and pattern, and the description adds nothing about whether the ID is a project UUID versus an external reference or what happens on an unknown ID.

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?

"Read a project by ID" states a specific verb and resource plus the access pattern (single lookup by identifier), which implicitly distinguishes it from list_projects and the various get_* siblings in other domains. The opening clause about "RetailHardHat projects records" is generic framing rather than added specificity, but the core sentence is unambiguous.

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?

"Use this when working with RetailHardHat projects records" implies the retrieval use case but never names an alternative such as list_projects or explains when a single fetch is preferred over a list. The conditions that select this tool must be inferred from the name and the single id parameter.

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