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

Annotations already declare this is a non-read-only, non-destructive write. The description adds genuinely new behavioral context: validation happens before any write (atomicity), and supplied Ideas preserve their order with the first two feeding planning input. These are meaningful traits not present in the annotations.

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 tight sentences, front-loaded with the core action and immediately followed by the required-vs-optional constraint and validation guarantee. No filler, though the Ideas-ordering detail is somewhat dense.

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 7-parameter create tool with no output schema and only basic annotations, the description covers validation, optionality, nested-idea ordering and planning semantics. It does not describe what the call returns (e.g., the created project identifier), which is a minor gap given no output schema.

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 semantics the schema cannot: that Ideas retain order and that only the first two become planning input. It also reinforces that everything but name is optional, going beyond the raw field docs.

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?

States a specific verb and resource ("Create a project from its details") and clarifies that supplied Ideas are attached to the project, which distinguishes it from the sibling create_idea. It does not explicitly name alternatives, but the scope is clear.

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 noting only the name is required and that Ideas, Batches, Works, Deliveries, workflows, repo and live URL "can all be added later," which helps an agent choose a minimal create. However, it never states when to create a project here versus creating its child entities via their own tools.

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