request_approval

Approve a merge pull request for a specific resource. Enables testing whether agents request and bind approvals correctly in synthetic environments.

TDQS

C2.5/5.0
Behavior2/5

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

There are no annotations, so the description carries the full burden. It only says 'issue approval' without disclosing whether this triggers side effects, requires permissions, is reversible, or returns any result. The name 'request_approval' suggests a request while the description implies granting, adding to the opacity.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no wasted words, but it is too terse to convey necessary details. The structure is a simple phrase, acceptable for brevity but not optimal given the lack of other documentation.

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

Completeness1/5

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

With no annotations, no output schema, and 0% parameter coverage, the description must be more complete. It does not explain what the tool returns, error conditions, prerequisites, or how approval integrates with the workflow. It is essentially unusable for an agent to understand the tool's full context.

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

Parameters2/5

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

Schema description coverage is 0%, so the description must explain the parameters. It mentions 'action' and 'a resource' but does not specify that 'resource_id' is a pull request identifier or how it relates to the approval. This adds only minimal context beyond the schema field names.

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?

The description clearly states the tool issues approval for the merge_pull_request action and a resource, distinguishing it from the sibling merge_pull_request tool which actually performs the merge. It uses a specific verb 'issue approval' and names the target action, though the term 'canonical' adds slight ambiguity.

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?

The description does not mention when to use this tool versus alternatives, such as using it before merge_pull_request or when an approval workflow is required. It provides no explicit when/when-not guidance, leaving the context of use unclear.

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