Rush SR Lap Analyzer

Find where a lap loses time

find_time_loss

Read-only

Use this when asking where am I losing time: rank the five distance sectors where one lap loses most against the best valid lap. Upload an AiM RaceStudio CSV export or paste its CSV text. Do not use for corner speeds or braking point comparison.

A4/5.0

Behavior4/5

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

Annotations already establish readOnly/destructive=false, so the safety profile is covered. The description adds genuinely useful behavioral context the annotations do not: the accepted input source and format ('AiM RaceStudio CSV export or paste its CSV text'). Auth, rate limits, and result shape are not addressed, but the input constraint is the material one here.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, front-loaded with the usage trigger before mechanism and exclusions, with no filler. Minor awkwardness in 'when asking where am I losing time' but nothing that wastes space.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be explained. However, with three parameters at 0% schema coverage, none marked required, and an undocumented nested file object, the definition leaves the agent guessing about the lap parameter and which input path is expected.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate, and it only partially does: it clarifies that file upload and pasted CSV text are alternative input paths, but says nothing about the lap parameter or the nested file object's fields (file_id, download_url, mime_type). Two of three parameters remain semantically unexplained.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a concrete verb and resource: rank the five distance sectors where one lap loses most against the best valid lap. That is specific enough to distinguish it from compare_laps and compare_sessions without opening either schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives a clear triggering question ('where am I losing time') and an explicit exclusion ('do not use for corner speeds or braking point comparison'). It stops short of naming the sibling tool that handles those excluded cases, so the routing is implied rather than fully closed.

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