redmine_update_news

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

No annotations are provided, so the description carries full burden. It discloses two key behaviors: partial update (only supplied fields are sent) and honoring the REDMINE_MCP_READ_ONLY environment variable for read-only mode. This adds significant context beyond the schema.

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 concise at two sentences, front-loading the purpose. However, it omits essential details about parameters, making it under-specified. Conciseness is good but at the expense of completeness.

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 4 parameters, 0% schema coverage, and no annotations, the description is incomplete. It covers basic behavior but lacks parameter descriptions, prerequisites, or error handling. An output schema exists but is not referenced. The description does not fully compensate for missing structured information.

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 0%, meaning the description does not explain any parameter. It only notes that only supplied fields are sent, but fails to define the meaning of title, news_id, summary, or description. The description should compensate but does not.

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 clearly states the verb 'Update' and the resource 'a news entry'. It specifies partial update behavior, distinguishing it from create or delete operations. Sibling tools include redmine_create_news and redmine_delete_news, so the purpose is specific and well-differentiated.

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?

No explicit guidance on when to use this tool versus alternatives. It implies usage for modifying an existing news entry, but lacks when-not-to conditions, prerequisites, or comparisons with other update tools. The description does not leverage sibling context for differentiation.

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