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

No annotations exist, so the description carries the full disclosure burden, yet it says nothing about whether this is a read-only informational lookup, whether pricing figures are involved, or what kind of content comes back. For a zero-arg info tool this is a modest gap, but nothing beyond the topic is disclosed.

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 short sentence with no filler and the key topic front-loaded. It is appropriately sized for a zero-parameter tool, though the fragment form leaves it slightly under-specified rather than genuinely concise.

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, no annotations, and no output schema, the description is the only signal, and it establishes just the subject matter. An agent knows roughly what topic this returns but not the shape of the answer or how it differs from the five sibling info tools.

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 no parameters, so there is nothing for the description to disambiguate; baseline 4 applies. The description does not introduce spurious parameter-like concepts.

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 identifies the resource (Fugentic's plans) and adds scope (what each one includes), but it is a noun fragment with no verb indicating retrieval. It also fails to distinguish itself from siblings like about_fugentic or platform_modules, which cover overlapping informational territory.

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 guidance on when to call this instead of about_fugentic, get_started, or platform_modules, nor any statement of what questions it answers. The agent must infer usage purely from the word 'plans'.

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