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

With no annotations, the description carries the full burden and does substantial work: it discloses polling intervals (5m/15m/30m/1h/4h/1d, plus 1m for positions), a sell-burst dump detector, three alert delivery paths, that alerts are free to read with the watch id, and an explicit price of $0.05 per call via x402/USDC. The payment/auth requirement and cost are exactly the kind of context annotations would otherwise supply. It stops short of stating watch lifetime/expiry or what happens on payment failure.

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?

Purpose is front-loaded in the opening phrase, and every clause contributes real information (intervals, delivery, price). However, it is a single dense run-on sentence stitched together with semicolons, which makes the mode split and pricing harder to extract than separate sentences would.

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?

For a 6-parameter tool with nested objects and no annotations or output schema, the description covers the operational picture (cadence, delivery, cost, two watch modes) reasonably well. What an agent still cannot determine is the valid value set for the required 'type' field and the structure of the strategy/position/notify objects, which are essential to a correct call.

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% across 6 parameters including two nested objects, so the description must compensate. It partially does — it implies the interval values, names webhook/Telegram/Discord channels (likely mapping to notify/webhook), and explains the strategy vs position mode split (likely the required 'type' field). But it never maps meaning onto parameter names or describes the notify/strategy/position object shapes, leaving most of the schema undocumented.

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 names a specific resource and behavior: a 24-hour memecoin watch that re-runs either a screen strategy or position exit rules on a schedule and alerts. That is distinguishable from siblings like memecoin_screen (one-shot screen) and memecoin_alerts (read alerts), though it never explicitly names those alternatives.

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?

Usage is only implied: you use this when you want continuous monitoring rather than a one-off check, and the two modes (strategy watch vs position exit watch) are described. There is no explicit when-not-to-use guidance and no reference to sibling tools like memecoin_exit_check or memecoin_alerts by name.

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