List Curated Taste Palettes

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered. The description adds useful scope facts — a fixed corpus of 57 palettes drawn from two sources — but says nothing about ordering, truncation by limit, or what a result entry contains.

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 front-loaded sentence with no filler; the count, sources and palette categories all carry information. It is close to minimal for the amount covered.

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 zero-required-parameter, read-only list tool with full schema coverage and no output schema, the description supplies the corpus size and taxonomy an agent needs to judge relevance. Only the return shape and limit behavior remain unstated, which is a minor gap.

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%, so both parameters are already documented and the schema's tag_filter even enumerates the exact tag values. The description's parenthetical tag list largely repeats that, and it never mentions the limit parameter, so no meaning is added beyond the schema baseline.

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?

The description names a specific verb+resource ('Tra cứu danh sách 57 bảng màu') and adds the source ('taste-skill và Corporate Brand') plus the palette families covered. It is clearly distinct from the sibling tools (slide/deck/asset builders), though it never states that distinction 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?

There is no statement of when to call this versus alternatives, no prerequisites, and no indication of what to do with the returned palettes (e.g. feed into canva_add_tasteful_slide). Usage is only inferable from the resource name.

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