case_file_create

Create a new case file as the top-level container for related operations like evidence, notifications, dossiers, and chats. Required before any subsequent actions.

Instructions

Creates a new case file — the top-level container for all related operations (evidence, notifications, dossiers, chats). Call this first before any other operation. Generate a UUID v4 for id. For useCaseId, use the general GoCertius use case: 063a016a-1d62-4b7b-a24f-7cf4d1d289bf unless a specific use case is required. Returns caseFileId needed for all subsequent calls.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A4.1/5.0

Behavior4/5

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

Description confirms the tool is a creation operation (non-read-only) and that it returns a caseFileId for subsequent calls. Annotations already set readOnlyHint=false, so description adds value by explaining the return behavior and giving specific parameter instructions (UUID generation). No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise with 4 sentences, each adding distinct value. It is front-loaded with the main purpose, then provides ordering guidance, parameter instructions, and return value. No wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool complexity (5 params, no output schema), the description explains the tool's role as a prerequisite for other operations and states the return value (caseFileId). However, it omits details on non-required parameters and does not describe error cases or side effects, which are minor gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description bears full responsibility for explaining parameters. It covers 'id' (UUID v4 generation) and 'useCaseId' (default value), but does not explain 'name', 'reference', or 'description'. With 5 parameters and 0% schema coverage, this gap leaves the AI agent without necessary semantic information for those parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Creates a new case file' and specifies it as the 'top-level container for all related operations', distinguishing it from siblings by instructing 'Call this first before any other operation'. It provides specific verb and resource identification.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly states when to call this tool ('first before any other operation') and provides instructions for generating id and default useCaseId. Does not include when-not-to-use scenarios, but the guidance is clear and actionable.

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