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

With no annotations, the description carries the full burden. It usefully discloses the return values (team_id, join_code) and the provenance model (entries attributed to author, only author can modify), but omits auth requirements for api_key, persistence/rate-limit behavior, and idempotency of creation.

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 short sentences, front-loaded with the core action and return values. The provenance sentence adds context without excessive bloat, though it reads slightly tangential to the creation action.

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?

No output schema exists so the description appropriately covers return values, and it sketches the sharing/provenance workflow. However, with no annotations and 0% param coverage, key details about parameters and operational constraints remain missing.

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 0% for 2 parameters (name, api_key), so the description must compensate and it does not. It mentions join_code output but says nothing about what name means or how api_key is used for authentication.

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 clear verb+resource ("Create a shared team memory") that an agent can immediately distinguish from sibling operations like team_join or team_list. It doesn't explicitly name those siblings as alternatives, but the creation intent is unambiguous.

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 offers no explicit when-to-use or when-not-to-use guidance. The mention of returning a join_code to share implies a workflow (create then others join), but it never points to team_join or states the condition for creating a new team versus joining an existing one.

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