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

No annotations are provided, so the description carries the full burden. It implies a mutation but does not say whether updates are partial (only supplied fields changed), whether tags are replaced or merged, whether completed applies to non-task nodes, what permissions are needed, or whether changes are reversible.

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?

One front-loaded sentence with zero wasted words. It is efficiently written, though its brevity is part of why key mutation semantics are absent.

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 eight parameters, no annotations, no output schema, and low schema coverage, this is under-specified. An agent cannot tell from the description whether omitted fields are preserved or how tags/color are handled.

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 25% (only nodeId and projectId documented). The description names five updatable fields (text, note, tags, color, completion status), but adds no semantics for them—no tag merge/replace behavior, no color format, and isTask is entirely omitted, leaving a three-parameter gap.

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?

It states a specific verb (Update) and resource (node) and lists the editable fields, so the intent is immediately clear. It does not explicitly distinguish itself from siblings like move_nodes, which is also a node mutation, so it falls short of a 5.

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 tool versus move_nodes, delete_nodes, or add_nodes, nor any prerequisites such as requiring a projectId and nodeId. Usage for editing fields is only implied by the field list.

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