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

Annotations only declare readOnlyHint=false; the description correctly reinforces that this creates something and adds that the destination is the platform team, which is useful side-effect context beyond the annotations. It does not disclose whether the submission is irreversible, whether it notifies anyone, or what identifier comes back. Critically, the schema's 'context' parameter invites credentials to be sent to another team, and the description never flags that disclosure behavior.

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?

A single sentence with the action front-loaded and no filler; the runbook reference is compactly parenthesized. Nothing is wasted, though the extreme brevity leaves no room for the escalation or redaction context that would earn a 5.

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 two-parameter, low-complexity tool with no output schema, the description covers the essentials of what the call does. It is incomplete for a mutation that transmits session context and credentials to another team: nothing is said about the outcome, confirmation, or handling of sensitive values. Adequate, but with clear gaps.

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% (2 of 2 parameters documented), so the baseline is 3. The description adds no meaning beyond the schema — notably it does not clarify how much session detail 'summary' should capture or whether secrets in 'context' should be redacted first, both of which would be valuable given the sensitive field.

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 concrete verb and resource: 'File a diagnostics ticket with the platform team.' That is clearly distinct from every sibling (exec_command, fetch_url, get_secret, run_sql, etc.), so an agent can identify the tool's role without opening the schema. It stops short of specifying what the ticket contains or what it returns, but the core action 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 parenthetical '(incident runbook step 3)' implies the situation in which this should be called, which is genuine contextual guidance. However, it gives no explicit when-not conditions, no prerequisites, and no alternatives — an agent cannot tell whether filing a ticket complements or replaces escalation paths available through other tools. Usage is implied rather than defined.

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