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

Annotations already declare readOnlyHint=false, destructiveHint=false and openWorldHint=false, so the mutation/safety profile is covered. The description adds nothing beyond the safety hints — no mention of required formId scope, ordering effects, or interaction with logic rules (e.g. isHidden being a show-rule target).

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 is front-loaded and wastes no words. But it is under-specified rather than genuinely concise — there is almost no information to compress, so brevity here is thinness, not efficiency.

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 mutation tool with six parameters and rich insertion-position semantics (after vs position vs parentId), the description is too thin. No output schema exists, and the description does not compensate by explaining placement behavior, chaining, or what a paragraph element represents in the form.

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?

Schema description coverage is 100%, so all six parameters (after, formId, content, isHidden, parentId, position) are already documented with useful detail, including the $prev chaining and HTML-entity warning. The description adds no parameter meaning, which is the expected baseline when the schema carries the load.

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 clear verb+resource ('Insert a paragraph element') and adds a hint of purpose ('for descriptive text'). However, among ~35 insert_* siblings it makes no attempt to distinguish itself from near-neighbors like editor_insertHeader or editor_insertList beyond the generic 'descriptive text' phrase.

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?

No guidance on when to use this versus the many other insert tools, nor when not to. The schema notes that omitting `after` 'appends to end (usually wrong)', but that caveat lives in the schema, not the description, and no alternative routing is offered.

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