get_latest_timeline

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

No annotations are provided, so the description carries full burden. It states the action 'Get tweets' but doesn't disclose behavioral traits such as rate limits, authentication needs, pagination, or response format. It mentions 'home timeline (Following)' which adds some context about scope, but lacks details on what 'Following' entails or any operational constraints.

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, efficient sentence that front-loads the core purpose without unnecessary words. It's appropriately sized for a simple tool, with zero waste or redundancy.

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 tool's low complexity (1 parameter) and the presence of an output schema (which handles return values), the description is minimally adequate. However, with no annotations and 0% schema coverage, it lacks details on behavior and parameters, making it incomplete for full understanding despite the output schema.

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 0%, but the description doesn't mention any parameters. The single parameter 'count' is undocumented in both schema and description, so the description adds no semantic value beyond the schema. With 1 parameter and low coverage, the baseline is 3 as it doesn't compensate for the gap.

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 verb 'Get' and the resource 'tweets from your home timeline (Following)', specifying it retrieves content from the user's following feed. It distinguishes from siblings like 'get_timeline' (which might be broader) by explicitly mentioning 'home timeline' and 'Following', though it doesn't explicitly contrast with other timeline-related tools.

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 provided on when to use this tool versus alternatives. It doesn't mention when to choose it over 'get_timeline' or other tweet-fetching tools like 'get_user_tweets', nor does it specify prerequisites or exclusions. The description implies usage for home timeline tweets but lacks explicit context for selection.

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