Remove unwanted connections from your knowledge graph by specifying the source, target, and type of each relation to delete.

Instructions

Delete multiple relations from your Memento MCP knowledge graph memory

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
relationsYesAn array of relations to delete
Behavior2/5

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

No annotations provided. The description does not disclose any side effects, error states, or constraints beyond the action of deletion. For a delete operation, more detail on idempotency or cascade effects would be expected.

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

Conciseness3/5

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

The description is very concise (11 words), but it sacrifices necessary context. It is minimally adequate but not an example of efficient depth.

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 no annotations, the description lacks details on return values, error handling, or behavioral context. It is incomplete for a tool with a single, complex parameter.

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 describes all parameters. The description adds no additional meaning beyond the schema, earning a baseline score of 3.

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

Purpose4/5

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

The description clearly states the tool deletes multiple relations, with a specific verb and resource. It distinguishes from siblings like create_relations and get_relation, though the scope is implied rather than explicit.

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 guidance on when to use this tool vs alternatives (e.g., no mention of deleting single relations vs batch, or when to prefer this over update_relation). The context is missing entirely.

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