sap_find_tools_by_category

Find on-chain tool descriptors by specifying a tool category name or numeric ID. Returns matching tools, with option to include full hydrated descriptors and set result limit.

Instructions

Find on-chain tool descriptors by SDK tool category name or numeric category.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
limitNoMaximum number of tools to return (default: 50)
hydrateNoWhether to include full hydrated tool descriptors in results (default: true)
categoryNoTool category name (e.g. "defi", "infrastructure") or numeric category ID
Behavior2/5

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

No annotations are provided, so the description must disclose behavioral traits. It only says 'Find' which suggests a read operation but does not mention side effects, error handling, or return structure. This is minimal transparency.

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?

The description is a single sentence of 10 words, front-loaded with the verb, and contains no superfluous information. Every word earns its place.

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

Completeness2/5

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

With no output schema and 3 parameters, the description does not explain the return value format, pagination, or how the limit and hydrate parameters affect results. It is incomplete for effective tool usage.

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%, so the schema already documents all three parameters. The description does not add any additional meaning beyond the schema, baseline score of 3 applies.

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 uses a specific verb 'Find' and resource 'on-chain tool descriptors' with a clear method 'by SDK tool category name or numeric category'. It distinguishes from sibling tools like sap_fetch_tool and sap_fetch_tool_category_index.

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?

The description implies when to use (when you need tools by category) and differentiates from siblings through context, but does not explicitly state when not to use or provide alternatives.

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