fusion_rename_comp

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the action ('rename') with no details on side effects, error conditions, idempotency, or permissions. It does not contradict annotations, but it fails to add behavior context.

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, front-loaded sentence with no filler. Every word is necessary, and it effectively communicates the core action and resource.

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 simple rename operation with a fully-described 5-parameter schema and an output schema, the one-line description provides minimal but adequate context. It doesn't explain relationships between parameters or edge cases, but the schema covers parameter meanings. This is a minimum viable description.

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?

The input schema has 100% description coverage, with clear definitions for item_name, old_name, new_name, track_type, and track_index. The description adds no additional parameter semantics, but the baseline is 3 due to full schema 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?

The description clearly states a specific verb ('Rename'), a resource ('Fusion composition'), and context ('on a timeline item'). This differentiates it from sibling tools like fusion_add_comp, fusion_delete_comp, and fusion_get_comp, which perform other actions on comps.

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?

No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, such as the timeline item needing an existing Fusion composition, nor any exclusions or references to sibling fusion_* tools.

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