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

With no annotations, the description carries the full burden. It usefully discloses that removal is not a hard delete because the note 'stays in history with who removed it and why,' and it names permitted roles. However, it does not clarify irreversibility, what happens if the note is already removed, or any error behavior.

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 description is short and front-loaded with the core action. The fragmentary sentence 'The writer, owner or office can' is slightly terse, but overall there is little wasted text.

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 two-parameter mutation tool with no annotations and 0% schema coverage, the description covers purpose, permissions, and history retention. It is still incomplete because it omits parameter guidance and does not explain edge cases or when to use it instead of update/add operations.

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 0%, so the description must compensate for both parameters. It only hints at the optional 'reason' parameter via 'why,' and says nothing about the required note_id parameter or its UUID semantics.

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 gives a specific verb and resource: 'Take a note off its record.' It is clear this is a removal/detachment action for a note, not an update or retrieval, though it does not explicitly contrast that with notes_update or notes_get.

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?

It states who is allowed to remove a note ('The writer, owner or office can') but gives no guidance on when to use this tool versus alternatives such as notes_update or notes_add. There are no exclusions, prerequisites, or alternative-routing instructions.

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