search_photo_packs

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

No annotations are provided, so the description carries the full burden. It does not disclose whether results are ranked by relevance, whether there is a result limit or pagination, or whether the search is fuzzy or exact — all things an agent needs to interpret the response for a search tool.

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 front-loaded sentence with no filler. It is efficiently sized for the tool's simplicity, though it is arguably under-specified rather than optimally concise.

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 one-parameter, no-output-schema tool this covers the essentials of what the tool does. However, with no annotations and search semantics undocumented (ranking, limits, matching behavior), an agent lacks enough to interpret or trust results fully.

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 parameter is documented as "Search keywords." The description adds no syntax, matching behavior, or format detail beyond that, so the 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 uses a specific verb ("Search") and resource ("photo packs") with a qualifying condition ("matching a query string"), so the agent knows it is a keyword-driven lookup. It does not explicitly distinguish itself from the sibling list_photo_packs or recommend_photo_pack, which would be the natural confusion points.

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 guidance on when to use this instead of list_photo_packs (browse all) or recommend_photo_pack (get suggestions). The agent must infer that searching is for a known keyword and listing is for enumeration, with nothing stated.

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