register_parameter

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

No annotations are provided, so the description carries the full behavioral burden. It says the registration is 'dynamic' but does not disclose what happens on name collision (overwrite vs error), whether required fields cause validation failure, whether changes persist, or whether the catalog is shared/mutated globally. For a mutation tool with zero annotation coverage, this is a real gap.

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?

A single front-loaded sentence with no redundancy. It is terse but every word counts; however it is arguably under-specified rather than optimally concise.

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?

With 10 parameters, 6 of them required, no annotations, and no output schema, the one-sentence description is inadequate. It omits collision behavior, permission/auth needs, and the effect on the live engine, which an agent needs before invoking a catalog-mutating tool.

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 90%, so the schema already documents nearly every field, and the required/enum structure is clear. The description adds no semantic detail about any parameter (e.g., the versionAdded format or category enum usage), so the baseline 3 applies.

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?

States a specific verb pair (registers/updates) and a specific resource (a parameter in the Anime.js v4 engine catalog). It is distinguishable from read-oriented siblings like list_engine_parameters and get_parameter_details, though it does not explicitly name them.

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 indication of when to use this tool versus add_custom_doc, get_parameter_details, or list_engine_parameters. No prerequisites or exclusions are given; the agent must infer that this is a write path from the verb alone.

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