remove_testers_from_beta_group

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

Goes well beyond the destructiveHint=true annotation by disclosing the entire confirmation protocol: a client confirmation prompt where supported, otherwise a two-phase preview-plus-confirmToken handshake governed by MCP_CONFIRM_MODE. It also clarifies the non-destructive scope of the removal. This is exactly the behavioral context an agent needs before invoking a destructive tool.

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 the core action and scope in the first clause, followed by the confirmation model. Two focused sentences with no filler, though the confirmation explanation is fairly dense and could be slightly 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 three-parameter destructive mutation with no output schema, the description adequately covers purpose, scope, and the confirmation workflow. Return/response shape is not described, but the creation of confirmToken in the fallback path is explained, which is the critical behavioral detail.

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 the schema already documents betaGroupId, betaTesterIds, and confirmToken in full detail. The description adds conceptual framing for the confirmation flow but no syntax or format meaning beyond the structured fields, so the baseline of 3 applies.

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 — 'Remove one or more beta testers from a beta group' — and immediately disambiguates from the delete_beta_tester sibling with '(does not delete the testers)'. An agent can tell exactly what this does without opening the schema.

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?

Usage is implied: it clearly concerns removing testers from a group rather than deleting them, but it never explicitly names when to prefer this over delete_beta_tester or add_testers_to_beta_group. No when-not conditions are given, leaving the agent to infer the group-vs-global scope distinction.

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