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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the description's real contribution is the returned shape (price in USD, photo, page link). However, it says nothing about pagination, result caps, or sort order, and the closing line about handmade Tel Aviv florists is pure marketing with no behavioral content.

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?

Two sentences, front-loaded with the operation and return fields. The final sentence about handmade bouquets earns no place in a tool definition and could be cut without loss.

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 zero-required-parameter read-only search, the definition covers what it returns, what can be filtered, and currency. The remaining gap is result-set behavior (how many bouquets come back, pagination), which an agent would want before calling.

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 75% and the enums are self-describing, so the schema already carries the parameter burden. The description adds a useful mapping ('budget' → max_price_usd) and confirms the four filter axes (occasion, colour, budget, words), but nothing about whether filters combine AND-style or what text matches beyond the schema note.

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 and resource ('List the bouquets for sale') and even names the returned fields (price, photo, link). Distinguishing it from the sibling get_bouquet is only implied through the plural 'list' framing, not stated.

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 gives the filter dimensions available, which implies when to use it (browsing/filtering a catalogue), but it never explicitly contrasts with get_bouquet or create_order, nor states any exclusions or prerequisites.

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