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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered. The description adds genuinely useful detail beyond that: exactly what state is destroyed (color and color_size), what is preserved (icon, custom workspace color), and that the full tile-style state is returned. Auth requirements and rate limits are still unmentioned.

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 tight sentences: the action and target are front-loaded, followed by the exclusion clause and the return behavior. 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 destructive mutation tool with full annotation coverage and an output schema, the description supplies everything an agent needs: the exact field set affected, the preserved state, and confirmation that resulting state is returned. Nothing material is missing.

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%, with viewId documented including URL extraction and ID discovery, and tile_ids documented including its source (tile_id from xtiles_get_tile_styles). The description's mention of color/color_size clarifies the effect rather than the parameters themselves, so it does not go meaningfully beyond the schema.

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 (clear) plus the exact resource scope (palette color of listed tiles on a page/view) and names the affected fields. It also enumerates what is NOT touched (icon, custom workspace color), which cleanly separates it from xtiles_set_tile_styles and xtiles_get_tile_styles.

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 scope statement ('this manages only the palette color', icon and custom workspace color unchanged) gives clear context for when this tool is the right one rather than set_tile_styles. It stops short of explicitly naming the alternative tool or stating when-not-to-use, so it is clear but not fully routable.

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