manage_codec_exclusion

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

With no annotations provided, the description carries the behavioral disclosure burden. It does state the three actions and the basic/non-plugin scope, but it does not mention side effects, persistence, idempotence, authorization requirements, or what happens when adding a codec that already exists.

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?

Two concise sentences, with the action and target front-loaded and the non-plugin clarification earning the second sentence. No filler or redundancy.

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 five-parameter mutation tool with fully documented enums and schema, the description plus input schema provides enough context for an agent to select and invoke it correctly. The lack of an output schema and absence of behavioral caveats keep it from a 5.

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 100%, so the baseline is 3. The description mostly restates the action semantics already present in the schema and adds no extra detail about status handling, accepted formats, or edge cases.

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 uses a specific verb phrase ('Add, remove or toggle'), a precise resource ('a codec in a library's basic transcoding include/exclude list'), and explicitly scopes it to basic non-plugin video/audio transcode settings. This clearly differentiates it from plugin-related tools such as manage_library_plugin.

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 explains that the tool applies only to the basic non-plugin transcode settings, which implicitly routes the agent away from plugin settings and related sibling tools. It does not explicitly name alternatives or state when not to use it, so it falls short of a 5.

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