Palette Blind Impl

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

No annotations are provided, so the description carries the full burden. It usefully discloses the three simulation modes and that it flags collision risk, but omits read-only status, required input format, and whether output is per-pair or aggregate — relevant gaps for a tool with zero annotation coverage.

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 compact clause with the primary action front-loaded and no filler. It is arguably too terse rather than bloated, which costs only slightly here.

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-value explanation is not required. However, with no annotations and an undocumented palette parameter, the definition is only minimally sufficient for an agent to call this correctly.

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 coverage is 0%: 'palette' is an undescribed string with no format, delimiter, or encoding guidance. The description never explains what syntax the palette string should take, so it fails to compensate for the schema's silence.

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 ('Simulate') and the exact resource (protanopia/deuteranopia/tritanopia simulation), plus a secondary output (collision risk flagging). It doesn't name the closest sibling (palette_contrast_impl) or otherwise distinguish itself within the large palette_* family, so an agent must still infer positioning.

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, when-not-to-use, or alternative-routing guidance. An agent could infer an accessibility-check context, but nothing in the text says when this should be chosen over palette_contrast_impl or palette_score_impl.

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