mesh_create

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

With no annotations, the description must carry the behavioral burden, and it does disclose one non-obvious side effect: a mesh sequence may be auto-created (auto_create defaults to True), plus it returns a generation status. It omits whether the operation is safe/idempotent, whether meshing is long-running or blocking, and what happens to existing sequences.

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?

Front-loaded one-line summary followed by a compact Args block and a return note; nothing is padded. The Args list largely restates schema keys, but each line adds a default or behavioral nuance, so it earns its space.

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?

Five parameters with zero schema coverage are all explained, and the return is at least named, so an agent can call this. Gaps remain: 'Mesh generation status' is never defined despite there being no output schema, blocking/latency behavior is unstated, and the relationship to mesh_create_sequence is unclear.

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, and it documents all five parameters with their default semantics (mesh_name defaults to all or 'mesh1' on creation, component_name defaults to the first component, model_name defaults to the current model). This meaningfully exceeds the schema, which supplies only titles and null defaults.

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 concrete verb and resource: 'Run one or all mesh sequences, creating a default sequence when needed.' That is clearer than the bare name mesh_create and conveys the both-broad-and-narrow scope. It does not, however, distinguish itself from the sibling mesh_create_sequence, leaving the agent to infer the difference.

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 explicit when-to-use or when-not-to-use guidance, and no alternative tool is named even though mesh_create_sequence and mesh_info sit right next to it. The defaults imply casual usage but the agent gets no routing signal for choosing this over its siblings.

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