schedule_tweet

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

No annotations provided. Description only hints at premium requirement but omits critical behaviors like error handling when scheduleTime is invalid, default behavior if omitted, or whether tweets can be posted immediately.

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?

Extremely concise two-sentence description with no unnecessary words. Key information is front-loaded.

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?

Adequate for a simple 2-param tool, but lacks details on default behavior, error states, or output (e.g., scheduled tweet ID). Could be more complete.

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%, and description adds context for scheduleTime by allowing 'next optimal window'. tweetText is straightforward. Description enriches parameters modestly.

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?

Clearly states the tool schedules tweets for optimal engagement, distinct from siblings like generate_tweet or search_tweets. The purpose is specific and informative, though 'optimal engagement' is vague.

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 versus alternatives. The 'PREMIUM feature' hint suggests access restrictions but does not elaborate on when scheduling is preferred over immediate posting or other tools.

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