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

Annotations already declare readOnlyHint=false, destructiveHint=true and idempotentHint=false, so the bar is to explain what is destroyed or made irreversible; the description instead frames the call as returning information and only says what it does NOT do. It adds some context (existing key connections can report a host-approved task and saved cadence; OAuth connections retain tokens), but the destructive and non-idempotent behavior flagged by annotations goes unexplained.

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 with no filler, but the lead sentence is opaque ("management information without a new key") and the closing negative clarification about schedulers is buried at the end rather than front-loading the actual effect of the call.

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 destructive, non-idempotent tool with a nested schedule object and no output schema, the description should explain what changes, what state is lost, and how schedule relates to the connection. It covers none of that, leaving an agent unable to predict the effect of calling it.

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 50%, and the undescribed half is the entire nested schedule object with six sub-properties (interval_minutes, timezone, times, task_id, task_name, execution_location). The description never mentions room_id or schedule; the phrases "saved cadence" and "host-approved task" gesture at the schedule fields but give no semantics for requiredness, interaction with task_id, or the local/cloud enum.

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 stated verb is "Returns ... information" about "private connection management information," which never says what the tool actually does to the connection — the name make_permanent and the title "Manage an existing private connection" imply a state change the description never names. It distinguishes key-based from OAuth connections, but that is scope detail rather than a clear action statement, and no sibling is named.

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 only guidance is the fragment "without a new key" and the caveat that "A report neither creates a scheduler nor verifies automatic return," which implies an exclusion without naming the alternative tool for those jobs (e.g., set_check_schedule). There is no explicit when-to-use or when-not-to-use statement.

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