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

With no annotations provided, the description carries the full behavioral burden. It discloses the return value ('Returns the project ID') and implies a side effect (creating a resource), but does not address permissions, idempotency, duplicate-name handling, or failure behavior. The return-value disclosure adds genuine context beyond the name, though the safety profile remains underexplained for a mutation tool.

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?

Three short sentences deliver the purpose, the return value, and the next workflow step with zero wasted words. Each sentence earns its place and the core action is front-loaded.

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 3-parameter creation tool with full schema coverage and no output schema, the description covers the essentials: what it does, what it returns (project ID, which output schema would otherwise convey), and the logical next step. Minor gaps exist around error conditions and prerequisites, but nothing an agent needs to invoke it successfully is missing.

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%, with all three parameters (name, accent, client) already documented in the input schema. The description adds no parameter-level detail beyond what the schema provides, which matches the baseline of 3 for high coverage.

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 uses a specific verb ('Create') with a clear resource ('a new project'), and it differentiates from sibling tools by explicitly naming create_node as the follow-up step for adding nodes. The workflow relationship to bulk_create_nodes and create_node is evident, so an agent can tell this tool apart without opening schemas.

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 usage by stating 'Add nodes with create_node after,' which signals the correct sequencing (create project first, then nodes). However, it never explicitly states when to choose this tool over alternatives, nor excludes cases like bulk project creation or when get_project/list_projects would be more appropriate.

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