list_camera_presets

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

With no annotations present, the description carries the full burden, and it does disclose two meaningful traits: results are limited to 'locally visible' presets (scope constraint) and the operation does 'not load' them (non-mutating, cheap). It stops short of stating permissions needed, error behavior when directories are absent or invalid, or whether ordering is guaranteed, so this is not exceptional honesty for an unannotated tool.

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?

One short, front-loaded sentence with no filler, and the scope qualifiers ('locally visible', 'without loading') are placed where they're read first. It could be slightly longer to cover the parameters without becoming bloated, but nothing present is wasted.

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?

An output schema exists, so return values needn't be explained, but for a two-parameter filesystem-adjacent listing tool with zero annotation coverage and zero schema descriptions, the definition leaves the agent guessing about directory semantics and failure modes. It is not sufficient to invoke the tool confidently when the defaults are empty strings.

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 for two undocumented parameters, game_dir and documents_dir, and it does not. It never explains that these are search roots, what happens when they're left at their empty defaults, or which one takes precedence, so the agent has no way to know how the parameters change the result set.

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 ('List') and a specific resource ('CamTool 2 preset filenames'), and the word 'presets' distinguishes it from the sibling list_camera_tools, which presumably lists tools rather than saved presets. It is clear what the tool returns; it just doesn't differentiate itself explicitly from list_pp_filters or the other list_* siblings.

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?

There is no explicit when-to-use guidance and no named alternative. The clause 'without loading them' hints that this is the cheap pre-flight step before loading a preset, but the agent must infer that intent and gets no guidance on when to prefer this over list_camera_tools or list_pp_filters.

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