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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, and the description usefully confirms this with 'opens nothing by itself'. It also discloses the return shape ('step by step screens, buttons, fields'), which annotations cannot convey. However, it never explains how the target ticket is identified given zero parameters, nor what happens when no ticket context is present.

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?

The core flow (returns instructions, does not act, use browser tools) is stated clearly, but it is padded with audience filler ('from ChatGPT, Claude or any AI agent') and a dated meta note about the Connect API and MCP server availability that does not help an agent invoke the tool.

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, and the description does cover what comes back (ordered screens/buttons/fields), which is the key missing piece. Still, for a zero-parameter tool it omits how a ticket is targeted, what the guidance looks like if the ticket is unspecified, and how it relates to the sibling ticket-modification tools.

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?

With zero parameters the baseline is 4, but the description leaves a real semantic gap: it never states that the ticket being updated comes from conversation context or is otherwise inferred. For a tool whose whole job is a specific ticket, the absence of any statement about target selection is a meaningful omission.

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 opening sentence says 'Update ticket in the user's own SysAid account', which reads like a write action, and only later does the text reveal that the tool actually returns step-by-step instructions rather than performing the update. The real purpose (guidance generation) is stated, but it is buried behind a misleading lead and no sibling is named for contrast.

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?

It gives a clear usage flow: call this to get the screen/button/field steps, then execute them with the cotlet_browser_* tools in the SysAid Cloud Browser. It also explains why this path is needed (no official SysAid MCP server). It does not say when to prefer a sibling such as cotlet_app_guide or sysaid_search_tickets instead.

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