TaskRail

get_fastest_completion_path

Find the fastest official way to complete a practical task. Use for requests like “how do I cancel,” “return an item,” “get a refund,” “file a warranty claim,” or “find the official form.” It returns ordered, source-backed steps and exact official links; it does not log in or submit the action.

A4.2/5.0

Behavior4/5

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

Description adds behavioral details beyond annotations: returns ordered steps, exact official links, and does not log in or submit. Annotations indicate readOnlyHint=false and openWorldHint=true, which are consistent. No contradictions.

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

Conciseness5/5

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

Two sentences, front-loaded with the core purpose, and examples immediately follow. No wasted words; every sentence adds value.

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

Completeness4/5

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

Description covers essential behavior, and since the tool has an output schema, return values need not be detailed here. One minor gap: no mention of error handling or rate limits, but acceptable given the tool's simplicity.

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 coverage is 100% with clear descriptions for all three parameters. Description reinforces that 'task' should be in ordinary language and 'state' is optional US code, but adds no significant new meaning beyond schema.

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?

Description clearly states it finds the fastest official way to complete a practical task, with examples like 'how do I cancel' or 'return an item'. It distinguishes from sibling tools (e.g., check_products_compatibility) by focusing on task completion rather than product comparison.

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?

Description explicitly lists example use cases and notes what the tool does not do (log in or submit action). However, it does not specify when alternatives like find_best_total_deal should be used, leaving some ambiguity.

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

A4.3/5.0

Disambiguation5/5

Each tool covers a distinct purpose: compatibility checking, new product deals, used alternatives, and task procedures. No overlap in functionality, and descriptions clearly differentiate them.

Naming Consistency4/5

All names use snake_case with a verb-noun pattern, e.g., check_products_compatibility, find_best_total_deal. Minor variance in noun phrase length (e.g., find_used_or_refurbished_alternatives is longer) but overall consistent.

Tool Count4/5

With only 4 tools, the set is compact but focused. It covers the core actions for product shopping and task guidance without unnecessary bloat. Could benefit from a broader scope, but count is reasonable for the niche.

Completeness4/5

The tools cover key product lifecycle phases: compatibility, new and used purchasing, and after-sales tasks. Missing general product search or reviews, but the core workflow (compare, buy, complete task) is well-served.
