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

Annotations already declare read-only, idempotent, non-destructive, and open-world behavior. The description adds useful behavioral context beyond annotations: technology categories and ordering, separate social-profile links, default 40 per brand, max 200, and that omitted counts are reported.

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 description is front-loaded with the core purpose and follows with output composition and limits. The long category enumeration is dense but earns its place by clarifying coverage; minor repetition around 'per brand' keeps it from a 5.

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?

With no output schema, the description carries the burden of explaining return structure, and it does so by listing categories, separating social links, and stating per-brand caps and omitted counts. It is nearly complete for an agent to call the tool correctly, though it could say more about domain scoping behavior.

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 parameter documentation is already strong. The description adds meaning to max_per_brand by stating the default 40, maximum 200, and that excess technologies are counted rather than listed, though it does not elaborate on the domains parameter beyond the schema.

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: it retrieves the technology stack each brand runs, with category ordering and social links separated. It is clear what the tool returns, though it does not explicitly differentiate itself from sibling tools such as get_full_brand_snapshot or get_homepage_analysis.

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 explains output shape and limits but gives no explicit guidance on when to use this tool versus alternatives. The schema notes that domains can be omitted for all tracked brands, but the description itself does not route the agent among siblings.

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