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

The Markdown-to-native-formatting disclosure is genuinely useful behavioral context not present in the annotations. However, with destructiveHint=true set on a create operation, the agent gets no explanation of what that means (e.g. whether an existing note with a matching name is overwritten), nor any note about permissions or folder-creation side effects.

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?

Two short sentences, front-loaded with the action, and the second sentence carries real information. The Markdown clause duplicates the schema description, which is the only waste.

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?

An output schema exists, so return values need no explanation, and all four parameters are documented in the schema. Still, the description never addresses the destructiveHint=false implication for name collisions or folder fallback behavior, leaving a create-with-overwrite ambiguity unresolved.

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 coverage is 100%, so the Markdown detail in the description largely restates the body parameter's schema description verbatim. The description adds nothing about the folder parameter's default or the ignored confirm flag, so baseline 3 is appropriate.

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 ("Creates a new note in Apple Notes"), which cleanly separates it from read_note, update_note, list_notes, search_notes and delete_note. It stops short of naming any sibling explicitly, so it is clear but not maximally differentiating.

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 use this versus update_note (append to an existing note) or obsidian_write_note / notion equivalents, and no prerequisites or caveats. The agent must infer that this is the creation path purely from the name.

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