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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety is covered. The description adds useful behavioral content by disclosing that returned records carry 'required auth' and MCP connection instructions, but says nothing about cost, truncation, or error behavior for invalid ids.

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 lead clause is well front-loaded, but the rest is one long run-on sentence stringing together roughly twenty return fields with commas, making it hard to scan. Nothing is truly wasted, but the absence of sentence breaks or grouping hurts readability.

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?

With no output schema, the description carries the burden of describing return values, and it does so thoroughly across materials, MCP servers, API providers and fonts. What is missing is routing context relative to the five sibling tools, but for a detail endpoint the coverage is close to sufficient.

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 coverage is 100% and already documents the id pattern, the 1-5 bounds, and the markdown/json response_format default. The description only restates the 1-5 id limit, so it adds no meaning beyond the schema — baseline 3 applies.

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?

Opens with a specific verb and resource ('Full details for 1-5 materials by id') and then enumerates the exact payload categories (license, install command, auth, prices). An agent can immediately tell this is the detail-fetch counterpart to codeitso_search and codeitso_browse, which return thinner results.

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?

Usage is only implied: the 'by id' phrasing signals it must be preceded by a lookup, and the 1-5 cap hints at batch hydration. There is no explicit statement of when to prefer this over codeitso_browse, codeitso_get_kits, or codeitso_find_models, and no guidance on what to do with an unknown id.

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