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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It says 'updates' but does not state whether operations are atomic, what permissions are required, how partial failures are handled, or what happens to content not touched by the replace operations.

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 front-loaded sentence with no wasted structure. The adverb 'surgically' is mild filler, but the description is otherwise tight and appropriately sized.

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 nested patch operations, no annotations, and no output schema, the description is too thin. It omits how operations are applied, whether they are ordered or all-or-nothing, and what the result of a successful patch looks like.

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 the schema already explains noteId and the ops structure. The description adds only the phrase 'replace operations,' which does not provide meaning beyond the schema's detailed op, path, range, and value fields.

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?

States a specific verb (updates) and resource (note in DevSpeak Notes Workspace) plus the mechanism (applying replace operations). It does not differentiate from any sibling note tool, but no such sibling exists in the provided list, so the description is adequately clear.

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 explicit when-to-use guidance, prerequisites, or alternatives are given. The description implies that it is for updating a note via replace operations, but an agent gets no help deciding between this tool and other possible note-editing approaches.

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