Behavior2/5

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

With no annotations, the description carries full burden for behavioral disclosure. It states that URLs will be synced 'first or exclusively', but fails to detail whether this replaces or merges existing priorities, if the operation is reversible, or any side effects on other syncing behavior. The behavioral insight is minimal.

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

Conciseness5/5

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

The description is a single, well-structured sentence that conveys the essential information without extraneous words. It is appropriately sized and front-loaded with the key action and resource.

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's simplicity (1 parameter, no output schema, no annotations), the description adequately states the purpose and effect. However, it lacks details about whether the operation is additive or replaces existing settings, any maximum URL count, or how it interacts with other config tools. This leaves minor gaps for an agent.

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. It adds context that the URLs are used for daily summaries and priority syncing, but does not explain URL format constraints beyond the schema's 'uri' format, nor specify if multiple URLs are additive or exclusive. It provides some semantic value but is not comprehensive.

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

Purpose5/5

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

The description clearly states the tool's purpose: setting publication URLs to be synced first or exclusively for daily summaries. The verb 'Set' and specific resource 'publication URLs' make the action unambiguous. It effectively distinguishes from sibling tools like 'substack_config_set_defaults' by focusing on priority/exclusivity.

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?

The description provides no guidance on when to use this tool versus alternatives such as 'substack_config_set_defaults' or 'substack_discover_subscriptions'. It does not mention prerequisites, exclusions, or context for invocation. The usage is only implied through the tool's purpose.

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