TDQS

B3.4/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds only the clarification that IID is the visible MR number; it says nothing about missing-project behavior, cross-namespace resolution, or what happens when the IID does not exist in the project.

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?

A single sentence, front-loaded with the verb and resource, with zero filler. Every word carries identifying information.

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?

With a fully described schema, annotations covering safety, and an output schema for return values, the description needs little more. It is adequate for calling the tool, though it never states prerequisites such as needing a resolvable project path or that namespace is optional when catalog-configured.

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%, so the schema already documents iid, project, namespace, and context_id; baseline 3 applies. The phrase "visible MR number" marginally clarifies the IID vs internal-ID distinction but adds no syntax or format detail beyond the schema.

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

Purpose4/5

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

Specific verb + resource ("Get merge request details") plus an identifying key ("by IID"), which distinguishes it from search/diff/changes siblings by implication. It stops short of explicitly naming which sibling to use when the IID is unknown.

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

Usage Guidelines2/5

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

No when-to-use or when-not-to-use guidance is given, and no alternative is named. An agent must infer that gl_mr_search is the discovery path and this tool is the lookup-by-IID path; nothing in the text states that.

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