Palette Score 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 does disclose the scoring rubric and flags that a non-zero exit signals an untrustworthy palette, which is genuine behavioral context, but it omits whether the tool is read-only, what auth it needs, or how failures are surfaced through the MCP interface rather than a CLI exit code.

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?

Compact and front-loaded: the scorecard output leads, dimensions follow, and the untrustworthy note closes. No wasted sentences, though 'CB-safety' is unexplained jargon that costs a little clarity.

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 need not be explained, and the description covers the scoring concept adequately. The gap is the input side – a required, undocumented 'palette' parameter – leaving the definition only just sufficient for invocation.

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 single 'palette' parameter has 0% schema description coverage, and the description says nothing about its expected format (hex list, file path, theme name, etc.). With the schema doing no work and the description silent, the agent cannot know what to pass.

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 output (a 5-dimension scorecard out of 20 with P0-P3 findings) and enumerates the dimensions scored, so the agent knows this is the evaluation/grading tool in the palette family. It does not explicitly contrast itself with close siblings like palette_slop_impl or palette_report_impl, so sibling differentiation is only partial.

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 statement of when to reach for this tool versus the twelve palette siblings, no prerequisites, and no mention of what a valid palette input looks like. Only the terse 'Exit non-zero = untrustworthy' note hints at usage.

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