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

Annotations already declare the mutation profile (readOnly=false, destructive=false, idempotent=false, openWorld=false), so the bar is lower. The description still adds genuinely useful behavior: default assignee is the current user, and the ticket lands in the project's backlog rather than an active state, which an agent would not know from the annotations alone.

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 with the core action and prerequisites front-loaded; no wasted preamble. The trailing clause 'as a ticket made in docket does' is slightly odd phrasing but conveys the backlog placement.

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?

There is no output schema, so the description should say what comes back from a create — presumably a ticket identifier or the created ticket object — and it does not. Aside from that missing return-value guidance, coverage of preconditions and defaults is adequate for a 7-parameter create tool.

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 86%, so parameters are largely self-documenting. The description restates the optional fields (description, start/end date, priority) without adding format or constraint detail, and only marginally clarifies assign_to_me ('assigned to the user unless asked otherwise'). Baseline 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 ('Creates a ticket') and adds scoping detail: the project must be one the user can open, and the ticket is assigned to the user by default. It does not name or differentiate against siblings like comment_on_ticket or my_tickets, but the create semantics are 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?

Implies when to use it via the precondition 'in a project the user can open' and the default-assignment rule, but never states when not to use it or which sibling to prefer (e.g. comment_on_ticket for discussion, search_tickets to find existing ones first). Usage is inferable rather than stated.

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