getGlobalFieldsMetadata

Read-only

Returns field metadata for a resource type and optional target type across all Polarion projects, enabling global field discovery without a project filter.

Instructions

Returns fields for the resource type and its target type in the Global context. Scope: spans every project (no project filter). To act on a single project, use getProjectFieldsMetadata instead.

Input Schema

Name	Required	Description	Default
`targetType`	No	The configured subtype for this enumeration or custom field (e.g. `requirement` for a Work Item type). Use `~` (without quotes) when the configuration applies to every subtype.
`resourceType`	Yes	The Resource Type.
`response_format`	No	Response detail level. concise removes redundant HTML and JSON:API metadata and may use a small default fieldset on large lists; detailed preserves the complete response. Defaults to detailed.	detailed

Output Schema

Name	Required	Description	Default
`data`	No
`links`	No

A4.5/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered; the description adds the meaningful behavioral constraint that results are global and unfiltered by project. It stops short of noting anything about result volume or how the two types are merged in the response, so it is strong but not fully rich.

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?

Three short sentences: purpose, scope constraint, and sibling alternative, in that priority order. Nothing is redundant and the routing information is front-loaded.

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

Completeness5/5

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

With an output schema covering return values, full annotations, and 100% parameter documentation, the only thing the description must add is scope disambiguation against the many other getFieldsMetadataFor* siblings, which it does directly.

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

Parameters3/5

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

Schema description coverage is 100%, including the `~` wildcard convention for targetType, so the schema already carries parameter meaning. The description only restates that a resource type and target type are involved, adding no syntax or format detail beyond the schema; baseline 3 applies.

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?

States a specific verb (returns), resource (fields metadata), and scope (Global context, resource type plus target type). It also implicitly distinguishes itself from the project-scoped sibling by naming that sibling explicitly, so an agent can pick between them without reading the schema.

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

Usage Guidelines5/5

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

Explicitly states the selection rule: this tool spans every project with no project filter, and directs the agent to `getProjectFieldsMetadata` for single-project work. Both the when and the when-not with the named alternative are present.

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