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

Annotations already signal readOnlyHint=false and destructiveHint=false, so the mutation nature is covered. The description adds meaningful behavioral context beyond the schema by disclosing that the project is seeded with default statuses, which tells the agent what side effect to expect. It does not mention permission requirements or duplicate key behavior, but for a simple create tool this is sufficient.

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 two sentences with no filler. The core purpose is front-loaded, the unique seeded-status behavior is included, and the usage guidance is appended in a compact second sentence. Every word earns its place.

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 simple create tool with 100% schema coverage, no nested objects, and no output schema, the description provides everything needed to select and invoke it correctly: the action, the unique initialization behavior, and a clear usage boundary. A return-value format is not required for correct invocation here.

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%, so the input schema already documents all three parameters (key, name, description). The description does not add parameter-level detail, but it does not need to: the baseline of 3 applies because the schema carries the semantic load.

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 action ('Create a new standalone project') and a concrete resource, and adds a unique behavioral detail: it is seeded with default To Do/In Progress/Done statuses. This clearly distinguishes it from siblings like update_standalone_project, get_standalone_project, and delete_standalone_project, so an agent can confidently select it.

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 explicitly says when to use this tool ('work that has no external tracker') and when not to use it ('for work already in Jira or Trello, use that provider's own tools instead'). This is direct, actionable guidance that prevents misuse and names the alternative category.

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