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

Annotations already disclose read-only and idempotent behavior. The description adds that results include before/after photos and locations, and that filtering by category or keyword is possible. It does not mention behavior like default pagination, ordering, or that only completed projects are returned (beyond the statement itself), but annotations cover the core safety profile.

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, dense sentence that front-loads the action and resource, then adds the two key usage notes (included data, filtering). Every word earns its place; no redundancy or filler.

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 simple read-only list tool with a documented schema, output schema, and safety annotations, the description is almost sufficient. The only gap is the lack of explicit routing to sibling tools for single projects or broader search, but all information needed to invoke this tool correctly is present in schema and description.

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 100%, so each parameter (limit, offset, search, category) is already described. The description's 'Filter by category or keyword' merely restates the schema's filter parameters without adding new semantics. Baseline 3 is appropriate.

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 uses a specific verb ('List') and resource ('completed remodeling projects'), adds content details (before/after photos, locations), and states the filtering capability. The 'completed' qualifier and the listing verb distinguish it from siblings like get_project and list_project_types.

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 description implies when to use it—when listing completed projects—but does not explicitly state when not to use it or name alternatives such as get_project for a single project or search_content for broader content search. There is no exclusion guidance, only implied context.

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