Create child ticket

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false and openWorldHint=true, so safety and world-interaction are covered. The description adds nothing beyond that — no mention of the parent link being required, permission requirements, or what happens if the parent is closed or missing.

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?

One short sentence with the scoping condition front-loaded. Efficiently written; the issue is under-specification rather than bloat.

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?

An output schema exists and every parameter is documented, which lightens the burden, but for an 11-parameter mutation tool the description says nothing about inheritance from the parent, required permissions, or post-creation effects. 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%, including enum-like value explanations for source, status, priority, so the baseline is 3. The description adds no meaning beyond the schema — for example it does not clarify when to use email vs requester_id, or how group_id/responder_id interact with the parent ticket's assignment.

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 (create) and resource (child ticket) and adds the key qualifier 'under an existing parent ticket', which distinguishes it from the sibling create_ticket. It stops short of explaining what a child ticket is in this system, 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?

No guidance on when to use this instead of create_ticket, no prerequisites about the parent ticket's existence/state, and no note on whether child tickets inherit parent fields. The agent must infer the selection criteria from the name alone.

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