kronos_preflight

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

No annotations are present, so the description carries the transparency burden. It does disclose a key behavioral trait: the tool costs $0.001 USDC via x402, implying a payment step. However, it does not explain what action the payment triggers, what data is involved, or what the tool returns.

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 very short and front-loaded, but it contains redundant 'kronos preflight' text and a vague 'Market Intel tool' phrase. It is concise in length but not optimally structured since the first half restates the name rather than adding functional value.

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 tool with a generic schema, no output schema, and a family of closely related Kronos sibling tools, the description is insufficient. It fails to explain what a 'preflight' does, what output to expect, or how it relates to kronos_signals, kronos_decision, etc. The only concrete detail is the cost.

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?

The schema has only a generic 'params' object with 100% description coverage, but that description ('Tool parameters as JSON object') adds no real semantics. The tool description adds no parameter information either, so it meets the baseline of 3 for high schema coverage but does not exceed it.

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 reads 'kronos preflight — Kronos Market Intel tool,' which largely restates the tool name and gives only a broad category ('Market Intel tool') without specifying what the preflight operation actually does. It neither names a verb action nor distinguishes itself from sibling Kronos tools like kronos_signals or kronos_risk.

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?

No guidance is provided on when to use this tool versus alternatives. It only mentions a cost of $0.001 USDC via x402, which is a pricing detail, not a use-case or selection criterion. The presence of many sibling tools makes this absence especially problematic.

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