testcases

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

With no annotations, the description carries the full behavioral burden. It does add real value beyond structured fields by disclosing that list returns total + has_more and defaults limit to 50. It is silent, however, on whether assign/update/add_note are idempotent, what permissions they require, or what side effects they have, leaving mutation behavior opaque.

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?

Purpose is front-loaded in one sentence, followed by a compact action table with endpoints and required params aligned for scanning. Every line carries actionable information with no filler.

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 six-parameter, five-action tool with no output schema and no annotations, the description is adequate on action routing and required params but thin on return values for mutations, error behavior, and the shape of the free-form fields object. It covers enough to invoke the tool but not enough to use it confidently across all actions.

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%, so the description must compensate, and it largely does: it maps project_id, testcase_id, note, fields, and limit to the actions that use them and notes the limit default and key fields (status, linked_vulnerabilities). It stops short of describing the fields object structure or allowed keys in full.

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 states a specific verb+resource ('Manage test cases assigned to AttackForge projects') and then enumerates five distinct actions with their HTTP endpoints, which cleanly separates this tool from siblings like testsuites and vulnerabilities. An agent can tell immediately that this operates on test cases within a project scope.

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?

Each action lists its required parameters (project_id, testcase_id, note, fields), which implies when each is applicable, so an agent can infer the correct action for a given intent. However, there is no explicit guidance on selecting this tool over siblings such as testsuites or remediation, and no exclusions.

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