Upgrade Plugin

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

The description discloses key behavior beyond annotations: it returns a shell command rather than performing the upgrade directly, and it mandates a restart. This adds context to the readOnlyHint=false and idempotentHint=true annotations, though it could elaborate on potential side effects or prerequisites. No contradiction with annotations.

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 description is three sentences with no wasted words. It front-loads the purpose, then gives essential execution instructions, and closes with a necessary user-facing step. Every sentence contributes value.

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?

Given no parameters and no output schema, the description adequately covers the tool's behavior and required follow-up actions. It could mention what the returned command actually does or any prerequisites, but the core workflow is clear.

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 and 100% schema coverage, the baseline is 4. The description correctly avoids discussing parameters, as there are none to explain, and the empty schema already conveys this.

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 'Upgrade context-mode to the latest version' with a specific verb and resource, clearly distinguishing it from siblings like ctx_execute, ctx_search, and ctx_purge. The purpose is unambiguous and directly tied to the tool name and title.

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 description provides explicit execution guidance: the returned command must be run via a shell tool, output displayed as a checklist, and the user told to restart. However, it does not explicitly discuss when to use this tool versus alternatives or when not to use it, so it falls short of a 5.

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