analyzeChat

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. It states the tool analyzes and summarizes, but lacks details on what 'recent' means (time window), how the analysis is performed, whether it requires specific permissions, rate limits, or what the output format looks like. This is inadequate for a tool with zero annotation coverage.

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 a single, well-structured sentence that efficiently conveys the core function without wasted words. It is front-loaded with the main action ('analyze') and resource ('recent Twitch chat messages'), making it easy to scan and understand quickly.

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?

Given the complexity of analysis/summarization, no annotations, and no output schema, the description is incomplete. It doesn't explain what 'topics and activity' entails, how results are formatted, or any behavioral constraints. For a tool that likely involves processing chat data, more context is needed to guide effective use.

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?

The input schema has 0 parameters with 100% coverage, so no parameter documentation is needed. The description appropriately doesn't discuss parameters, focusing instead on the tool's function. A baseline of 4 is applied since no parameters exist, and the description doesn't add unnecessary param details.

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 clearly states the tool's purpose with specific verbs ('analyze', 'provide') and resources ('recent Twitch chat messages', 'summary of topics and activity'). It distinguishes itself from siblings like 'getRecentChatLog' (which presumably retrieves raw logs) by emphasizing analysis and summarization rather than data retrieval. However, it doesn't explicitly contrast with all siblings, so it falls short of a perfect score.

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 implies usage when a summary of chat topics/activity is needed, but provides no explicit guidance on when to use this versus alternatives like 'getRecentChatLog' for raw data or other tools for chat management. There's no mention of prerequisites, timing considerations, or exclusions, leaving usage context somewhat vague.

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