edit_milestone

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

No annotations are provided, so the description carries the full burden of behavioral disclosure for a mutating tool. It discloses nothing about partial-update semantics (all 7 params are optional), the side effects of state_event close/activate, whether the milestone must already exist, or error behavior. This is a significant transparency gap for a write operation.

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 seven-word sentence with zero filler, front-loaded with the action verb and resource. It is efficiently minimal, though arguably too sparse for a 7-parameter mutation tool; that under-specification is penalized under contextual completeness rather than conciseness.

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?

With 7 parameters, a state-transition enum (close/activate), no annotations, and no output schema, a single sentence leaves critical information undisclosed: whether omitted parameters are left unchanged, what state_event does, and what the response looks like on success or failure. The description is not sufficient for confident invocation by an agent.

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 100%, and each parameter already has a clear description in the schema, so the baseline of 3 applies. The tool description itself adds no parameter-level meaning beyond the generic 'edit' verb, but no compensation is needed because the schema fully documents all parameters.

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 uses a specific verb ('edit') with a clear resource ('milestone') and scope ('GitLab project'). The phrase 'existing milestone' implicitly contrasts with create_milestone, delete_milestone, and the read-only milestone siblings, but it never names them or explicitly differentiates behavior, leaving some inference to the agent.

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 guidance is given on when to use this tool versus create_milestone, delete_milestone, or get_milestone. With seven milestone-related siblings in the toolset, the description provides no context, exclusions, or alternative routing — the agent must infer the use case entirely from the word 'edit'.

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