close_ticket

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

Annotations already declare destructiveHint=true, idempotentHint=true and readOnlyHint=false, so the safety profile is covered structurally. The description adds one genuinely new fact — that closing flags an incomplete associated chain — but does not say whether that flag blocks the close, warns only, or is reversible, which matters for a destructive mutation.

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 short sentences, front-loaded with the action and followed by the advisory caveat. No filler, though it is arguably under-specified rather than optimally concise.

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, so return values need not be explained, and annotations carry the safety profile. Still missing for a destructive lifecycle tool: whether a chain-incomplete close is blocked or merely flagged, required ticket state, and permission requirements.

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 reported at 0% for the single required parameter, so the description is expected to compensate — and it says nothing about ticket_id, its format, or where it comes from. With only one simple parameter the impact is limited, but the gap is real.

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 description states a specific verb and resource ("Close ticket"), which is unambiguous on its own. However it offers no differentiation from the many sibling ticket tools (read_ticket, update_ticket, promote_ticket, etc.), so an agent gets no help distinguishing this specific lifecycle action.

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?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives such as promote_ticket or set_chain_status. The only context given is a behavioral note about the chain-incomplete flag, which is not usage routing.

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