twitch_clips

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

With no annotations, the description carries the burden. It does not state that data is public (no auth), limited to the last 7 days, and sorted most-viewed first. However, it does not disclose rate limits, error behavior, or what happens when no clips exist, leaving some gaps.

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?

Three sentences total, well front-loaded with the core action and resource. The second sentence redundantly says 'Twitch channel's clips' again, but overall the wording is compact and covers essential constraints and returns.

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 2-parameter tool with no output schema and full schema coverage, the description adds important context: time window, sorting order, return field list, and data source. This is enough that an agent can confidently invoke the tool without further documentation, though pagination behavior is not elaborated since limit is already described.

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%, so the input schema already fully documents both 'login' (with a concrete example) and 'limit' (default 20, max 100). The description adds no new parameter meaning beyond the schema, so the baseline of 3 for full schema coverage is appropriate.

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 and resource: 'Get a Twitch channel's clips' and adds constraining details (last 7 days, most-viewed first) with a clear list of returned fields (title, view count, duration, curator, game). This clearly distinguishes it from sibling Twitch tools like twitch_videos or twitch_streams.

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 guidance is given on when to use this tool versus the many Twitch-related alternatives (twitch_videos, twitch_streams, twitch_search, etc.). There is no mention of alternatives, exclusions, or selection criteria, so an agent must infer usage from the tool name alone.

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