create_mindmap

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

With no annotations, the description carries the full burden and does meaningful work: it discloses layout behavior, per-branch coloring, default output path, and the returned absolute .excalidraw path. It does not mention overwrite behavior, but the file-creation side effect is transparent.

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 compact, front-loaded with purpose, and organized into behavior, Args, and Returns sections. Every sentence adds useful information; only a small amount of redundancy exists between the first and second sentences.

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?

The required root is explained as a nested tree and the schema provides MindmapNode label/children details, while output_path and return behavior are covered. The undocumented theme parameter and the absence of overwrite semantics are minor gaps, not blockers.

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?

Despite 0% top-level schema description coverage, the Args section gives real meaning to root, title, and output_path and adds the default output path. Theme is the one parameter left undocumented in both schema and description, preventing a 5.

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 opening sentence is explicit: 'Create a mind map diagram from a tree structure.' It names the exact verb, resource, and input shape, and the layout/coloring details make it easy to distinguish from siblings like create_flowchart and create_org_chart.

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?

The description implies when to use the tool via 'from a tree structure,' but it never states alternatives, exclusions, or how to choose between this and the many sibling diagram tools. Context for invocation is present, but routing guidance is not.

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