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

No annotations are provided, so the description carries the full burden. It discloses authentication requirements ('Uses the feed's publisher token or the admin token'), which is valuable behavioral context. However, it does not mention side effects, idempotency, or return behavior, leaving some transparency gaps.

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 two sentences with zero waste. It front-loads the core purpose, then adds the trigger condition and authentication note in a concise, structured manner.

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?

The description adequately covers purpose, trigger, and authentication for a simple reporting tool. However, with no output schema or annotations, it does not explain return values or error conditions, which is a minor gap. Overall, the essential context is present.

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 100%, so the baseline is 3. The description does not add parameter-level detail beyond what the schema already provides, but it does reinforce the semantic link between 'subscription' and 'action' through phrases like 'subscriber's agent completes one of your callable actions.'

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 tool reports an action outcome for a subscription, explicitly identifying it as the 'acted' signal for the analytics funnel. This specific verb+resource combination distinguishes it from sibling tools like hello_aigent_event_log.

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 gives an explicit trigger condition ('Call this after a subscriber's agent completes one of your callable actions'), providing clear context for when to use it. It does not mention alternatives or exclusions, but the trigger is specific enough to guide tool selection.

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