x_follow_profile

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

With no annotations, the description carries the full disclosure burden. It does add value by noting the tool verifies the resulting follow state and acts on the active account, but omits auth requirements, what happens if already following, rate-limit behavior, and failure semantics.

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?

A single tight sentence that front-loads the action and pairs it with the verification outcome. No padding or redundant restatement of the name.

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?

For a simple two-parameter action tool with no output schema, the description covers the core action and hint at verification. However, with zero annotation coverage it leaves mutation-side behavioral details (permissions, idempotency when already followed, error handling) undocumented.

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 100%, so tabId and username are already documented. The description adds no syntax or format detail beyond the schema, so the baseline of 3 is appropriate.

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 states a specific verb (follow) and resource (X profile), plus the added scope of verifying the resulting follow state from the active account. It is clear on its own, but does not distinguish itself from the confusing sibling x_follow_profile_task, leaving an agent to guess at the split between them.

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 explicit when-to-use guidance, prerequisites, or exclusions are given. The presence of the near-identically named sibling x_follow_profile_task makes routing ambiguous, yet the description offers no condition to pick one over the other.

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