set_palette

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

No annotations provided, so description carries full burden. It only says 'set', which implies mutation, but does not disclose side effects: does it affect existing colors on the sprite? Does it require specific permissions? No mention of reversibility or impact.

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?

The description is concise at one sentence, but it sacrifices necessary details. It could be structured to include parameter explanations or usage hints.

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?

Given no output schema and no annotations, the description is incomplete. It fails to explain the relationship between filename and colors, or the resulting state of the palette. For a mutation tool, more context is needed.

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 0%. The description only explains the 'colors' parameter (hex strings). The 'filename' parameter is not explained at all—ambiguous whether it is a sprite filename or palette file name. This is insufficient for a tool with two required params.

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 clearly states it sets the active sprite palette using hex colors. Verb 'set' and resource 'active sprite palette' are specific. It distinguishes from related tools like 'extract_palette' and 'get_palette' but could be more explicit about replacing the entire palette or adding to it.

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?

No guidance on when to use this tool versus alternatives like 'apply_palette_preset' or 'remap_colors_in_cel_range'. The description implies general usage but lacks when-not-to-use or prerequisites.

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