redmine_api_request

Call any Redmine REST API endpoint, including version-specific and plugin endpoints, using HTTP methods and paths.

Instructions

Call any Redmine REST API endpoint. This is the escape hatch for the complete Redmine API surface, version-specific endpoints, and plugin endpoints. Paths are resolved under REDMINE_URL.

Tool call template

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

Input Schema

Name	Required	Description
`body`	No	JSON request body for POST, PUT, PATCH, and DELETE requests.
`path`	Yes	REST path, for example /issues.json, /issues/123.json, /projects/my-project/wiki/index.json, or a plugin endpoint.
`query`	No	Query parameters. Array values are appended repeatedly.
`method`	Yes	HTTP method.
`headers`	No	Additional headers. Authentication and content headers are managed automatically unless explicitly overridden.

A3.7/5.0

Behavior2/5

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

With no annotations, the description carries the full burden of behavioral disclosure. It only mentions path resolution under REDMINE_URL and does not address error handling, authentication, rate limits, or response format, leaving significant gaps for a generic API caller.

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 two sentences, front-loaded with purpose, and contains no filler. Every word earns its place, making it highly efficient.

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

Completeness3/5

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

Given the tool's complexity (6 params, no output schema) and lack of annotations, the description is minimally adequate. It explains the role as an escape hatch but lacks details on usage context, error handling, and authentication, which are important for a fallback tool.

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 coverage is 100%, so baseline is 3. The description does not add any extra meaning to the parameters, which are already well-described in the schema. No improvement or degradation.

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 'Call any Redmine REST API endpoint' and positions it as the 'escape hatch' for endpoints not covered by sibling tools. It explicitly distinguishes from the specific sibling tools by indicating it covers version-specific and plugin endpoints.

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?

The description implies usage for cases not covered by sibling tools ('escape hatch'), providing clear context. However, it lacks explicit when-not-to-use or alternatives guidance, which would elevate it to a 5.

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