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

Beyond the annotations (readOnly=false, destructive=false, openWorld=true) the description adds substantial context: nothing is sent to the client, no confirmation is requested, an unknown email silently creates a new client, and the status field determines lead vs. job. It also discloses the Cotlet API-key access requirement, which annotations do not cover.

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 content is front-loaded reasonably well, but it repeats itself: 'Nothing is sent to the client' appears in the second sentence and again as 'This call sends nothing to the client, so it asks no confirmation.' The trailing archive/delete and API-key remarks dilute the core message.

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?

With no output schema, the description should say what a successful call returns (e.g., the new project's id or fields), and it does not. It covers the input-side side effects and auth well, but leaves the return behavior unspecified for a mutation tool.

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 100%, so the baseline is 3, but the description adds real meaning for two parameters: client_name is only used when the email creates a new client, and status must match an existing project status and controls lead/job classification. It doesn't add much for title, tags, notes, or project_date.

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 specific verb and resource ('Creates a project from a title and a client email') and goes further to describe the client-creation side effect. It is very clear what the tool does, but it never explicitly distinguishes itself from siblings like dubsado_get_project or dubsado_update_project_status.

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?

Usage is implied rather than stated: 'New project for a new or existing client' tells the agent this is the entry point for project creation, but there is no explicit when-to-use/when-not or comparison to alternatives (e.g., the update or list tools).

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