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

Annotations only declare destructiveHint=false and openWorldHint=false; the description adds the non-obvious side effect that a project is created alongside the org, which materially changes what the agent should expect after the call. It still omits permission/ownership requirements and whether the caller becomes a member, but the key mutation side effect is disclosed.

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?

Two short sentences with zero padding; the side effect is front-loaded and the return shape follows. Every clause 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?

With a full output schema and 100% parameter coverage, the description only needs to cover behavior, and it does so for the compound creation. Remaining gaps are minor: org name uniqueness and whether the returned projectId is null when firstProjectName is not supplied.

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 both parameters are already documented, making 3 the baseline. The description adds marginal meaning by tying firstProjectName to the "seeded first project" concept, but does not say what happens to the returned projectId when that optional parameter is omitted.

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 team organization") plus the compound side effect of seeding a first project, which distinguishes it from a plain org creation. It does not explicitly differentiate itself from the sibling create_project, which also exists in this namespace.

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?

There is no guidance on when to use this versus create_project, list_orgs, or get_org, and no prerequisites or exclusions are stated. The agent must infer that this is the "org plus starter project" path purely from the single word "seed".

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