Behavior2/5

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

No annotations are provided, so the description carries full burden for behavioral disclosure. It reveals this is a read/listing operation focused on the Update Center but does not explain what the result set looks like, whether it requires network access, or any details about pagination/limits. For a read-only search tool with zero annotation coverage, more is needed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is efficiently structured with a one-line purpose statement plus an Args list. No wasted words, and the Args section improves scannability. It's appropriately concise for a simple two-parameter tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool is straightforward (list available plugins with optional filter), the description covers the core purpose and both parameters. However, with no annotations and no clarity on the output format or return semantics for a search operation, the completeness is adequate but not thorough.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. The Args section explains query (filter, empty=all) and session_name (session to use), adding meaning to both parameters. However, it doesn't clarify the format of the query (fuzzy vs exact, wildcards) or what 'session' means. It provides basic but not rich parameter semantics.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool searches available plugins for installation from the Jenkins Update Center, distinguishing it from jenkins_list_plugins (which likely lists installed plugins). The verb 'search' plus 'available plugins from Jenkins Update Center' provides good specificity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no explicit guidance on when to use this tool vs alternatives. While the sibling name jenkins_list_plugins suggests a contrast (installed vs available), the description does not name or clarify this distinction or mention any exclusions. The description implies usage context ('for installation') but doesn't provide alternatives.

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