twitter_favorite_tweet

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

Annotations already indicate it's a write (readOnlyHint=false) and non-destructive (destructiveHint=false). The description adds the requirement for write capability and the existence of a reverse operation. It does not disclose other traits like rate limits or idempotency, but these are not critical for a simple like action. No contradiction with annotations.

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?

Two efficient sentences: first states action and input requirement, second covers authentication and reverse tool. No unnecessary words; front-loaded with actionable information.

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 no output schema, the description does not explain return values (a minor gap). It covers the core use case and key prerequisites. The proxy recommendation for writes is only in schema descriptions, but the overall context is mostly complete for an agent to execute the action successfully.

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% with detailed descriptions for all 7 parameters. The description only mentions 'Provide the tweet id or url', which aligns with the schema's `id` and `url` params but adds no extra value. Baseline 3 is appropriate since schema already does the heavy lifting.

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 action ('Like (favorite) a tweet') and the resource (a tweet), with the specific scope 'AS your authenticated account'. It distinguishes from siblings by naming the reverse tool twitter_unfavorite_tweet. This makes the purpose unambiguous.

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 provides input guidance ('Provide the tweet id or url') and an important prerequisite ('Requires write capability behind your key'). It also names the reverse tool. However, it lacks explicit comparison with related actions like retweet or bookmark, leaving the agent to infer when to use this tool over alternatives.

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