get_current_page_info

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

No annotations are supplied, so the description carries the burden. It implicitly signals a safe, parameterless read and discloses the shape of the result at a high level, but says nothing about failure modes (no tab open, non-Twitter page), whether it works outside X, or the exact page-type set.

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 front-loaded sentence with no filler; the parenthetical efficiently enumerates the payload without padding.

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?

With no output schema and no annotations, the description is the only source of contract information. Listing 'URL, page type, etc.' helps but the 'etc.' leaves the return contract underspecified, and nothing covers error or edge-case behavior.

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?

Zero parameters, so there is nothing to disambiguate; the baseline of 4 applies. The description correctly implies no arguments are needed.

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?

States a specific verb ('Get information about') and resource ('the current page open in the Twitter/X tab'), plus example fields (URL, page type). It does not differentiate itself from the nearby sibling scrape_current_view, which reads as overlapping in intent, so it falls short of a 5.

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?

There is no statement of when to call this rather than scrape_current_view, get_extension_status, or any scrape_* sibling, and no preconditions (e.g. must a Twitter/X tab be active). Usage is only implied by the phrase 'current page'.

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