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

Annotations declare readOnlyHint=true, but the description explicitly describes creating teams, saving entries and deleting entries — write operations that modify state. This is a direct contradiction of the structured metadata. The otherwise useful context (5,000 keys per team, $0.002 USDC per call, secret-code auth) cannot offset announcing the tool as read-only.

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 compact clauses that front-load the resource, then the flow, then quota and cost. Little waste, though the cost/x402 note could arguably be tighter.

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 multi-action tool with no output schema and near-zero schema coverage, the description supplies useful commercial and auth context (price, quota, code-based access) but leaves parameter-to-action mapping and return behavior unexplained, and the read-only annotation misrepresents its write capabilities.

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 only 14% (just the action enum), and 6 of 7 parameters are undocumented. The description names the action verbs but never maps parameters to them — which of key/value/query/name/code/team apply to save vs get vs search vs delete must be guessed.

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 resource and scope ('Team memory: shared notes for a group of agents') and enumerates the full action set the tool exposes. It is clearly distinguishable from generic siblings, though it doesn't explicitly contrast with the nearby 'memory' or 'kb' tools.

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?

It implies the operating flow ('Create a team to get a team id and secret code; any agent with the code can save, get, list, search and delete entries'), which tells an agent to create first and then pass the code. However, there is no explicit when-to-use guidance versus the sibling 'memory' tool, nor any stated exclusions.

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