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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: not whether it is read-only or mutating, not whether it generates a plan, calls an LLM, requires credentials, or has side effects. For a planner tool with zero annotation coverage this is a complete gap.

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?

It is short, but the brevity reflects under-specification rather than conciseness; the single sentence is a namespace label, not information. Nothing is front-loaded because nothing substantive is said.

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 annotations, no output schema, and only a one-line name restatement, the definition gives an agent nothing needed to decide whether or how to call it, especially against the dense set of sibling planning tools. It is inadequate for the tool's apparent planning role.

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 and schema description coverage is 100%, so the schema already explains 'widgetType' with examples ('click-to-call or meeting'). The description adds no further meaning, but the baseline for high coverage with no compensating need is 3.

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 is only a namespaced restatement of the tool name plus a parenthetical alias ('widget-planner'). It contains no verb describing what the tool actually does, and with ~90 sibling tools including several '*integration.plan' variants, an agent cannot tell it apart. This is a tautology rather than a purpose statement.

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 about when to use this tool, when not to, or which sibling to prefer (e.g. shared::integration.plan, shared::embedded.layout.plan, shared::headless.integration.plan). Nothing in the text routes the agent.

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