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

Annotations already declare readOnlyHint=true and openWorldHint=false, yet the description adds real behavioral detail beyond them: one answer per fact, unconfirmed facts carry no answer ("never a limit, never a zero"), scope is limited to this project's own installs, browser/phone reads as a device family with no facts, and unrecognised hosts read unknown rather than production. This is meaningful disclosure of output semantics and failure modes, though nothing about caching, refresh cadence, or response shape.

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 first sentence is well front-loaded, but the middle sentence is a densely packed list stitched with em-dashes that is hard to parse on first read, and the caveats about phone/browser and unrecognised hosts could be tightened. Information is mostly load-bearing, but the structure is convoluted rather than crisp.

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 parameters and no output schema, the description must carry the meaning of the returned facts, and it largely does: it names the fact families and explains the source/confirmation semantics and the unconfirmed-fact rule. A reader still cannot know the exact field names or return shape, but for a zero-argument read tool this is close to 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?

The tool takes zero parameters, which is the baseline-4 case; there are no arguments whose semantics could be clarified. Schema coverage is moot at 0 params.

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 resource — what the project's hosting platform allows — and enumerates the facts returned (time and memory limits, countdown, processor clock, work-after-reply), each with source and confirmation time. It lacks a crisp leading verb and never contrasts itself against siblings like boosthis_connection_status or boosthis_crash_risk, which also sound environment-related, so an agent must infer differentiation from the text alone.

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?

Usage is only implied: read this when you need platform capability facts for this project. The description says "Read from this project's own installs" and explains how phone/browser and unrecognised hosts behave, but never states when to prefer this tool over alternatives or what other tool to use instead.

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