Activate a knowledge base to include it in full-text search results.

Instructions

Enable a knowledge base so it appears in search results

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
nameYesKnowledge base name
Behavior2/5

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

No annotations are provided, and the description does not disclose behavioral traits like idempotency, reversibility, permissions, or side effects. The burden falls on the description, which is insufficient.

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?

Single sentence that is front-loaded and efficient, conveying the core purpose without extraneous words.

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?

Covers the basic purpose but omits behavioral details such as what happens if the KB is already enabled, error conditions, or relationship to sibling tools like kb_disable. Adequate for a simple tool but has gaps.

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 parameter is already described. The description adds no additional meaning about the name format, validation, or constraints beyond 'Knowledge base name'.

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 clearly states the action (enable) and the resource (knowledge base) with a specific outcome (appears in search results). It distinguishes from siblings like kb_disable, kb_list, etc.

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

Usage Guidelines2/5

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

No explicit guidance on when to use this tool versus alternatives, such as prerequisites or conditions. The agent must infer from context that it's used for currently disabled KBs.

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