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

With no annotations provided, the description carries the full burden of behavioral disclosure, yet it only reveals cost (1 credit/call) and app lineage. It is silent on response shape, pagination semantics beyond the schema's own last_id note, ordering, filtering side-effects, or error/rate 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?

The description is two tight, front-loaded clauses with no filler words. Every element serves a purpose (identity, context, cost). It is brief to a fault, but for sheer economy of words it earns a high mark.

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 simple 3-optional-param list endpoint with full schema coverage, the minimalism is partly forgivable, but given the absence of annotations, output schema, and sibling differentiation, the description leans on the agent to infer too much. It's adequate, not helpful.

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% with decent per-parameter descriptions (e.g., the last_id cursor pattern and the 'don't send to get all' note for task_type_filters), so the baseline 3 holds. The description itself adds no parameter insight, but none is strictly needed.

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 name and title convey it retrieves the v1 home feed, and the description adds a mildly useful 'Old Sora App' contextual note. However, it never differentiates itself from its near-twin siblings get_v1_feed_top, get_v1_feed_images, and get_v1_feed_videos, so the agent must guess what makes 'home' distinct.

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 is given. The description never explains when to choose this over the other v1 feed variants or the get_v2_feed family. Only implicit signal is the 1-credit cost, which doesn't aid tool selection.

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