snapchat get segments

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description adds that results are paginated via next_cursor and that full native configuration is preserved, which is useful behavioral context, but it says nothing about rate limits or what a partial/empty result looks like beyond pagination.

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 short sentences, front-loaded with the core action, with zero filler. The only structural weakness is that the second sentence is a tangential clarification that adds ambiguity rather than value.

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 an output schema present and 100% schema coverage, the description needn't explain return values or parameters, and annotations cover safety. What is missing is the one thing only the description can supply: a precise definition of 'segments' and how this differs from snapchat_get_adsquads and snapchat_get_targeting.

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 all three parameters are documented inline, so the baseline is 3. The description only echoes pagination (next_cursor) and the account scoping; it adds no format, default, or range detail 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?

The first clause gives a clear verb+resource ('List Snapchat segments in the selected account'), but 'segments' is never defined, and the trailing sentence 'An ad squad is an ad group/ad set' actively muddies the purpose by implying segments are ad squads — which conflicts with the sibling snapchat_get_adsquads. An agent cannot confidently tell whether this lists audience segments or duplicates the adsquad lister.

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?

No when-to-use guidance and no alternatives named, despite a crowded sibling set (snapchat_get_adsquads, snapchat_get_targeting, snapchat_get_entity). The ad-squad remark reads more like a misplaced glossary note than routing guidance, so the agent gets no exclusions or prerequisites.

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