list_trackers

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

No annotations are provided, so the description carries the full burden. 'List all available' implies a complete, non-mutating read, but nothing states read-only safety, whether results are global vs project-scoped, or whether an authenticated Redmine session is required. The parenthetical examples are the only added context.

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?

A single, front-loaded sentence with no filler. The resource and scope lead, and the examples add value rather than padding.

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 trivial zero-parameter, read-only enumeration tool with no output schema, the description covers what it is and roughly what it returns (tracker names/types). Only scoping (global vs project-specific) is left unstated, a minor gap at this complexity level.

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?

The tool takes zero parameters, so the baseline is 4; there is nothing for the description to disambiguate, and it correctly signals that no filtering input is expected.

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?

Specific verb ('List') plus resource ('trackers in Redmine') with example values (Bug, Feature, Task), so the agent knows exactly what comes back. It is distinguishable from siblings like list_statuses and list_projects only by the resource noun; there is no explicit differentiation statement.

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 explicit when-to-use, prerequisites, or alternatives are stated. Usage is implied by the nature of the tool (fetching tracker IDs/labels before creating or filtering issues), which an agent can infer, but the description does none of that work.

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