addSection

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

No annotations provided, so the description must disclose behavior. It only states 'creates', but doesn't mention side effects, permissions, idempotency, or error conditions. For a creation tool, this is insufficient.

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 a single sentence (bilingual) which is too terse for a tool with 5 parameters. It lacks structure and additional context, making it underspecified. Conciseness should not sacrifice completeness.

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?

No output schema, no description of return values, error cases, or pagination. For a tool with multiple parameters and no annotations, the description is incomplete. It fails to provide enough context for correct invocation.

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 the schema already documents parameters. However, the description adds no extra meaning beyond the schema. For example, it doesn't explain that parentId makes a subsection or that suiteId is required for multi-suite projects. Baseline 3 is appropriate.

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 explicitly states 'Creates a new section in a TestRail project', which clearly identifies the verb and resource. The sibling tools (e.g., addCase, addSuite) are distinct, so no confusion. However, it doesn't elaborate on the context or preconditions.

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 moveSection or updateSection. No mention of prerequisites (e.g., project must exist) or when not to use it. The description lacks any contextual usage advice.

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