record_filament_colour

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

No annotations are provided, so the description carries the full behavioral burden. It does disclose the Kiln Pro entitlement requirement and hints that the record affects colour suggestions, but it says nothing about write-side effects, permissions, validation of observed values, reversibility, or response behavior.

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 useful purpose statement is front-loaded in one sentence, but the next two paragraphs are purely subscription promotion and do not help an agent decide how to invoke the tool. Roughly two-thirds of the description is noise.

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 an eight-parameter mutation-like tool with no annotations and no output schema, the description is far too thin. It conveys the basic intent and entitlement requirement but leaves key parameter semantics, usage context, and behavioral effects undocumented.

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 only 25% across eight parameters, so the description needed to compensate. It only vaguely gestures at the colour being recorded and explains nothing about brand, line, material, observed_hex format, observed_by, printer_id, or note.

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 first sentence clearly states a specific verb and resource: recording the actual printed colour of a filament so Kiln can improve its colour suggestions. It does not name or distinguish any sibling tools, and the remaining two paragraphs are promotional rather than clarifying purpose.

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 description implies that this is used after printing to feed back an observed colour, but it gives no explicit when-to-use guidance, prerequisites, or alternatives. There are many sibling tools related to recording outcomes and colour matching, yet none are referenced.

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