romaco_go_to_timestamp

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

No annotations are provided, so the description fully handles transparency. It mentions the difference in behavior between normal mode and replay mode (viewport vs cursor). However, it does not disclose potential side effects (e.g., data loading) or error conditions (e.g., out-of-range timestamp).

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 extremely concise with only two sentences. The first sentence states the core action and mode differentiation, and the second provides clear use cases. Every word serves a purpose.

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 simple tool with a single parameter and no output schema, the description fully explains what the tool does, when to use it, and the parameter's unit. Nothing essential is missing.

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 input schema has 100% description coverage, already stating the parameter 'timestamp' is in milliseconds. The description repeats this unit information, adding marginal value beyond the schema. No additional semantic details are provided.

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 action: moving the chart viewport or replay cursor to a specific timestamp. It uses a specific verb ('move') and resource ('viewport/replay cursor'), and the context of 'revisit historical setups' distinguishes it from sibling tools like zooming or loading candles.

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 provides clear usage context ('revisit historical setups or scrub through past patterns') but does not explicitly state when not to use it or mention alternative tools. It is adequate for guiding the agent.

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