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

Annotations already declare destructiveHint=true, readOnlyHint=false, and openWorldHint=false, so the safety profile is covered without the description. The description adds nothing beyond that baseline: no statement about irreversibility, cascade effects on graph completeness, or whether confirmation is needed. With annotations present the bar is lower, but zero added context still merits a 2.

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

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

The single sentence is front-loaded and free of waste, but the brevity is under-specification rather than discipline for a destructive operation. There is no structure beyond one clause.

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

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

For a destructive graph mutation with no output schema, the definition leaves important questions unanswered: what happens to dependent work items or concepts, whether the deletion is reversible, and what errors occur for an invalid ID. The annotations cover the destructive flag but not these operational details.

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

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

There is a single required parameter, relation_id, with 100% schema description coverage, so the schema already carries the semantics. The description adds no meaning about ID format or provenance, which the baseline-3 rule permits given high coverage.

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

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

"Delete a relation" is a verbatim restatement of the tool name delete_relation, so it conveys no information an agent couldn't derive from the identifier itself. It does not distinguish this from sibling deletion tools like delete_concept or explain what a "relation" is in this graph model.

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

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

There is no when-to-use guidance, no prerequisites, and no mention of alternatives such as delete_concept or whether a relation must be detached from work items first. The agent must infer entirely from the name that this is the removal counterpart to create_relation.

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