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

There are no annotations, so the description carries the transparency burden. It discloses pricing, payment methods (x402 or API key), proprietary computation, educational disclaimer, and connection to a live table. This is substantial behavioral context beyond the schema, though it doesn't state potential side effects (unlikely for a read-only listing tool).

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 a single dense paragraph but front-loaded with purpose and key fields. Payment details and disclaimers are essential but could be shorter. Still, all content serves a purpose for an API tool with authentication nuances.

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 tool is relatively simple (2 optional params, no output schema). The description covers purpose, fields, ordering, filters, limits, payment, and disclaimers. Missing explicit return format (envelope vs bare array) but output schema is absent, so the description could have clarified that, a minor gap.

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 coverage is 0%, so description must compensate. It does: explains limit default and cap (50) and asset_class filter purpose. It adds an ordering note (composite_score DESC) and mention of optional query parameters, helping the agent construct calls. Slight gap: no explicit value format for asset_class.

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 explicitly states it returns per-symbol ATR%/volume squeeze scoring with fields (symbol, atr_pct, volume_usd, galaxy_score, composite_score, asset_class, rank) and ordering (composite_score DESC). It names the underlying table and clearly distinguishes itself from siblings by product and fields.

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?

It mentions optional filters (asset_class, limit) and default/cap, but does not explicitly say when to use this tool over others. However, given sibling names like get_anomalies, get_signals, get_market_regime, the description's focus on volatility squeeze makes use-case inferable, though direct alternatives are not named.

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