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

Adds substantial behavior beyond the annotations: the public page is enabled by default and controlled by publicPageEnabled, names must be unique per workspace (duplicate = validation error), Free-plan caps fail with plan_limit and details, and idempotencyKey replay semantics. These are non-obvious operational traits the annotations (readOnly=false, idempotent=true) cannot convey.

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?

Front-loaded with purpose and return values, then constraints and failure modes. It is dense and somewhat long, but each sentence carries distinct information (default public page, uniqueness, plan limit, idempotency, untrusted content), with little waste.

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 names the return fields (projectId, slug, name, appUrl, publicUrl) and explains key error conditions (duplicate name, plan_limit). Combined with the 100%-covered schema, an agent has everything needed to call and interpret it.

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 all three parameters are already documented. The description restates the idempotency replay behavior and name uniqueness rather than adding syntax or new meaning, so the baseline 3 for a fully-covered 3-param schema is appropriate.

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 (create) and resource (empty project) with its purpose (group documents, e.g. a data room). It is trivially distinguishable from siblings like lnkdrp_list_projects, lnkdrp_update_project, and lnkdrp_delete_project.

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?

Gives clear context for when this tool applies ('create an empty project to group documents, e.g. a data room for one deal') and notes the project starts empty, implying documents are added later via add_docs_to_project. There is no explicit comparison against an alternative creation path, but none of the sibling names suggest one.

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