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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds real context about what the profile is and who consumes it (article editor, AI content tools), but says nothing about permissions, scoping, or what happens when no profile is configured.

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?

Front-loaded with the core action in the first sentence, followed by a definition and an Args block. All sentences earn their place; only the Args restatement of 'required' duplicates the schema slightly.

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 tool with no output schema, the description adequately sketches the profile's contents, so an agent knows roughly what comes back. However, the profile-vs-samples distinction is left unexplained and the user_intent analytics parameter is never mentioned, so the definition is not fully complete for a 3-parameter tool.

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 only 33%, so the description must carry weight. It does clarify brand_id ('the brand to inspect (required)') and enumerates view's values ('profile' or 'samples'), but it never explains what each view returns or how they differ, leaving the enum choice ambiguous. Partial compensation, not full.

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 ('Read the brand's writing-style profile') and then defines what the resource actually is (tone, vocabulary, do's/don'ts, sample sentences). No sibling tool retrieves writing style, so differentiation is implicitly fine. It stops short of 5 only because it never says how this relates to the many adjacent content/knowledge getters.

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?

It gives one usage context: 'Useful when generating brand-aligned copy outside Trakkr.' That is implied rather than explicit when-to-use guidance, and no alternative tool is named or excluded for the in-app case. Adequate but leaves the agent to infer when to prefer this over get_knowledge or list_brands.

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