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

With no annotations provided, the description carries full burden but offers minimal behavioral insight. It mentions 'deterministic conflict handling' which hints at behavior, but doesn't clarify if this is destructive (likely yes for source entity), what permissions are needed, or what the output contains. For a mutation tool with zero annotation coverage, this 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.

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

The description is a single, efficient sentence with zero wasted words. It front-loads the core action and includes essential qualifiers ('duplicate', 'deterministic conflict handling') without redundancy, making it easy to parse quickly.

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 the tool's complexity (merging entities with conflict resolution), no annotations, and an output schema (which reduces need to describe returns), the description is moderately complete. It covers the what and how at a high level but lacks details on behavior, side effects, and parameter usage that would be needed for confident invocation.

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 description coverage is 0%, so the description must compensate but adds little parameter detail. It implies 'source_entity_id' and 'target_entity_id' parameters through context, and mentions 'attribute_conflict' handling, but doesn't explain conflict types or the default 'target_wins' behavior. This provides some meaning beyond the bare schema but leaves key gaps.

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 action ('merge'), the resource ('duplicate source entity into a target entity'), and the method ('deterministic conflict handling'). It distinguishes from siblings like 'update_entity' or 'delete_entity' by specifying merging with conflict resolution, but doesn't explicitly differentiate from all potential alternatives like 'connect_entities'.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., entities must exist), when merging is appropriate (e.g., for duplicates), or what happens to the source entity post-merge. Without such context, the agent lacks clear usage direction.

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