Behavior3/5

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

Annotations already indicate idempotentHint=true (idempotent), destructiveHint=false (non-destructive), and readOnlyHint=false (write operation). Description adds the daily limit and confirmation return, but does not elaborate on side effects or authorization needs. Adequate but not extensive.

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?

Concise with two brief paragraphs. Could be slightly more streamlined by removing the Args/Returns section, but overall efficient. Every sentence adds value.

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 a simple tool with one required parameter, no output schema, and existing annotations, the description covers the essential: purpose, limit, and return. Lacks context about prerequisites or error cases, but sufficient for agent use.

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?

Only one parameter (channel_id) with 100% schema coverage. The description re-iterates it is required but adds no new semantic meaning beyond the schema's description. Baseline 3 is appropriate.

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?

Description clearly states 'Subscribe to a channel' with a verb and resource. It distinguishes from sibling tools like neptime_unsubscribe and neptime_get_subscriptions. The purpose is unambiguous.

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

Usage Guidelines4/5

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

Provides a daily limit (50 subscriptions per day), offering practical guidance. Does not explicitly state when to use vs alternatives, but the sibling context implies it is for subscribing as opposed to unsubscribing or listing subscriptions.

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