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

Annotations already mark this as readOnlyHint=true and openWorldHint=false, so the safety profile is known; the description goes further by disclosing that there is no installer binary, the engine arrives via `uv`, the UI is a local web panel on 127.0.0.1, and — critically — Claude must be closed and reopened after connector registration. That restart prerequisite is genuine operational context an agent could not get from the schema or 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?

The critical constraint ('NÃO EXISTE APLICATIVO PARA BAIXAR') and the restart caveat are front-loaded and emphatic, which helps scanning. However, the trailing [EN] sentence largely re-states the Portuguese content, and the bilingual duplication plus rhetorical framing ('o detalhe que quase todo mundo esquece') add length without new 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?

For a guidance-style tool with one optional parameter, no output schema and annotations covering the safety profile, the description supplies the essential operational caveats (no installer, uv-based engine, local panel, required Claude restart). It is complete enough to act on; only the routing relative to sibling tools remains unaddressed.

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?

There is a single optional parameter whose schema description coverage is 100% ('windows | mac | linux'). The description merely restates the same platform values ('Windows, Mac ou Linux') without adding syntax, defaults, or behavior for omitting it, so it does not exceed the schema baseline.

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 and resource — 'O passo a passo para instalar o MOTOR do AlgoMaker' — and explicitly rules out the common misconception of a downloadable app. It does not, however, differentiate itself from the sibling algomaker_comecar, which by name suggests a potentially overlapping 'getting started' purpose.

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 implied rather than stated: the agent is told the commands are 'comandos que o próprio agente roda' and that a Claude restart is required after registering the connector, which hints at when in the flow this is needed. But there is no explicit 'use this when X, use algomaker_comecar when Y' routing, so the agent must infer the boundary between install, licensing and onboarding siblings.

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