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

Annotations are all false, so the description carries full burden. It discloses that operations are add/remove/set and that 'denormalized names + team counters stay in sync automatically,' providing valuable behavioral context beyond the schema. No contradictory statements.

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 description is long due to many examples, which are helpful but could be more structured or condensed. It front-loads the core purpose but then lists many relationships in a dense paragraph, making it somewhat verbose.

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?

Given 6 required parameters, no output schema, and empty annotations, the description provides a comprehensive overview of the linking functionality and possible relationships. It lacks details on error handling or return values, but is sufficient for an agent to understand the tool's core behavior.

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?

Schema coverage is 0%, but the description lists required parameters (event_id, entity, item_id, relation, target_ids) and mentions op as add/remove/set. The examples clarify how entity and relation combine, adding meaning beyond the raw schema enums. However, it does not describe each parameter's format or constraints individually.

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?

The description clearly states the tool's purpose: 'Interconnect production items on a live event — link an item to others across the graph.' It provides numerous specific examples of relationships (e.g., task→project, vendor→projects), making it distinct from sibling tools like create, update, delete, and list production items.

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?

The description implies usage through extensive examples of valid relations and entity types. It does not explicitly state when not to use or contrast with alternatives, but the examples strongly guide appropriate use cases. A clear context is given, but no explicit exclusions.

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