nexus_create_milestone

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

With no annotations provided, the description carries full burden for behavioral disclosure. 'Create a new milestone' implies a write operation but reveals nothing about permissions required, whether creation is reversible, what happens on success/failure, rate limits, or system constraints. For a 10-parameter mutation tool with zero annotation coverage, this is critically inadequate.

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 maximally concise at three words with zero wasted language. It's front-loaded with the essential action and resource, though this brevity comes at the cost of completeness for other dimensions.

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 complex creation tool with 10 parameters, no annotations, and no output schema, the description is severely incomplete. It doesn't address behavioral aspects, usage context, or what the tool returns. While the schema handles parameters well, the description fails to provide the necessary context for safe and appropriate tool invocation.

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%, providing clear documentation for all 10 parameters including their types, descriptions, and constraints. The description adds no parameter information beyond what's in the schema, so it meets but doesn't exceed the baseline expectation when schema coverage is complete.

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 clearly states the action ('Create') and resource ('a new milestone'), making the purpose immediately understandable. It distinguishes from siblings like 'nexus_update_milestone' by specifying creation rather than modification. However, it doesn't explicitly differentiate from other creation tools like 'nexus_create_project' or 'nexus_create_concept' beyond the resource name.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, when to choose this over other creation tools, or contextual constraints. Given the sibling list includes multiple creation and update tools, this lack of differentiation is a significant gap.

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