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

Annotations only declare destructiveHint=false, so the description carries most of the burden. It adds real behavioral context beyond annotations: the new team inherits 'the primary team's numbers and whispers,' and duplicate copies reps and hours. It does not restate auth (deferred to the schema) or note confirmation/irreversibility semantics.

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 sentences, no filler, with the create-vs-duplicate split front-loaded and the ID-source caveat trailing. 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?

For a 6-param mutation tool with no output schema and only a destructiveHint annotation, the description covers the two actions, inheritance behavior, and ID provenance. It leaves permissions (owners/admins only, present in the schema) and any response/return expectations unaddressed, but is close to sufficient.

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 meaning the schema lacks: it tells the agent where sequence_id and team_id originate (get_settings), which affects how the tool will be invoked in practice. No format/syntax detail beyond that is added.

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 specific verbs and resource: 'Create a new team (ring group)... or duplicate an existing team with its reps and hours.' It distinguishes the two modes of operation and names the relevant configuration artifacts (follow-up sequence, ring mode, reps), so an agent can immediately separate it from delete_team and update_team_members.

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 provides a prerequisite pointer ('sequence_id and team_id come from get_settings'), which is useful, but gives no explicit when-to-use / when-not-to-use guidance against siblings such as delete_team or update_team_members. Usage is implied by the tool name and action enum rather than stated.

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