get_latest_timeline

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

With no annotations, the description should disclose behaviors like pagination, rate limits, or deduplication logic. It only mentions parameters tersely (count, seen_tweet_ids, cursor) without explaining their behavior or side effects.

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 sentence, concise and front-loaded. However, it is so brief that it sacrifices useful details, making it only adequately concise but not well-structured with explanatory sections.

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 context of social media timeline fetching, the description lacks information on pagination, ordering, deduplication, and rate limits. While an output schema exists, the description is insufficient for proper usage.

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%, so the description must compensate. It lists parameter names and defaults/optionality but does not explain what 'cursor' or 'seen_tweet_ids' do, missing the opportunity to add meaning 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 description clearly states it gets tweets from the user's home timeline (Following), which is a specific verb and resource. However, it does not explicitly differentiate from sibling tool 'get_timeline', which likely serves a similar purpose.

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 on when to use this tool versus alternatives like 'get_timeline' or 'get_user_tweets'. The description does not mention prerequisites, limitations, or exclusions.

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