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

Annotations already declare readOnly, idempotent, open-world and non-destructive behavior, so the safety profile is covered. The description adds genuinely useful context beyond that: results include per-technology scan counts and last-seen timestamps, and output is paginated. It stops short of describing pagination limits or total-count behavior.

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 verb and scope, then appends result content and pagination. No wasted words, though the clause list is slightly crammed for one sentence.

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?

An output schema exists, so return values need not be spelled out, and the tool has no required parameters. The description covers the query axes and pagination adequately; the remaining gap is the semantics of page/limit, which is minor given the low-risk read-only profile.

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 0%, so the description must compensate. It does cover q (name search) and category, but page and limit are only gestured at by the word 'paginated', with no explanation of defaults (1 and 20) or their meaning. Partial compensation for a four-parameter tool.

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 (search) and resource (web technologies detected across the archive), plus the two search axes (name via q, or category) and what each result carries. This clearly separates it from get_technologies_by_scan and get_popular_technologies, which are scan- or popularity-oriented, though no sibling is named explicitly.

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 (browsing technologies by name or category), but offers no explicit when-to-use/when-not guidance or pointers to sibling tools like get_technology_stats or get_technology_combinations. Usage must be inferred from the sibling list.

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