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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds the useful content disclosure (what facts are included) but nothing about response shape, size, or whether sections are conditionally present. With annotations carrying the safety burden, this is adequate but thin.

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 no filler; every listed item helps an agent judge relevance. The long enumeration is dense but each clause earns its place, though a short lead-in naming the tool as the general entry point would improve structure.

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 read-only, single-optional-parameter info tool with no output schema and full annotation coverage, the description is nearly sufficient: it tells the agent what domains of information exist. What remains unstated is whether all sections are always returned and how large the response is.

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 locale parameter is fully documented in the schema with an enum and default. The description adds nothing about the locale (e.g., that Portuguese answers draw on the same underlying data), so baseline 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 names a specific resource (the Developh studio profile) and enumerates the facts it contains: address, team, services, sectors with case studies, pricing, contact. It is clear what the tool returns. However, it does not differentiate itself from siblings like list_case_studies or request_contact, whose subject matter it explicitly overlaps with.

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 routing to alternatives. An agent could infer this is the general-purpose profile call versus the more targeted siblings, but the description never says so, leaving the choice between studio_info, list_case_studies, and request_contact to guesswork.

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