Palette Report Impl

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

With no annotations, the description carries the full behavioral burden. It usefully discloses the aggregation behavior, the PASS/FAIL JSON shape, and that an exit code encodes the verdict — a non-obvious trait. It says nothing about permissions, side effects, idempotency, or whether it writes anything to disk, which for a "report artifact" tool 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?

Two compact sentences with the purpose front-loaded and zero filler; "Exit code = verdict" is an efficient way to convey a behavioral detail. Slightly jargon-dense ("AI-slop") but no sentence 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 spelled out, and the description still usefully summarizes them. However, with an undocumented input parameter and a crowded 13-tool sibling set, it omits the palette input format and any explicit guidance on choosing this aggregate over the individual gate tools.

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 sole parameter `palette` has 0% schema description coverage and the description never explains what it accepts (hex list, file path, palette name?). The gate names hint that the input is a color palette, but the format is left entirely to inference, so the description fails to compensate for the coverage gap.

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 concrete verb (aggregate) and a concrete resource (a single PASS/FAIL JSON report), and names the four gates it rolls up (contrast, color-blind, AI-slop, scorecard) — which map directly onto sibling tools like palette_contrast_impl, palette_blind_impl and palette_slop_impl. That implicitly differentiates it as the umbrella tool, though it never says so explicitly.

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?

"One-shot acceptance artifact" implies the context (a final go/no-go check rather than incremental inspection), which hints at when to reach for it over the individual gate tools. But there is no explicit when/when-not statement or named alternative, so the agent must infer the routing.

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