github_list_pull_requests

Read-onlyIdempotent

List pull requests in a GitHub repository, filtering by state or author to quickly assess review status and identify pending changes.

Instructions

List pull requests for a repo.

Args: repo (required): owner/repo format. state: One of: open, closed, all. author: Filter to PRs by this username. project_id: Authenticated Project UUID. project_ref: Exact project correlation reference. connector_account_ref: Project-bound connector account alias. idempotency_key: Stable business-action identity. effect: Required and must be read; Spring verifies it. approval_ref: Approved platform task UUID when resuming a write.

A3.6/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive behavior. The description adds platform context such as 'effect: Required and must be read; Spring verifies it' and approval_ref semantics, but the 'when resuming a write' language is confusing for a read-only tool. It does not contradict the annotations, but it also does not disclose meaningful behavior like pagination, ordering, or authentication needs.

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

Conciseness4/5

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

The description is brief and front-loaded with 'List pull requests for a repo.' The parameter list is compact and each field gets one line. Some platform boilerplate and the odd 'when resuming a write' note add minor noise, but overall the structure is clean and scannable.

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?

With an output schema present, return-value documentation is not needed, and all parameters are at least named. However, there is no usage guidance, no distinction from sibling GitHub tools, and the purpose of several authenticated platform fields is unclear. The description covers the mechanics but not enough surrounding context for confident invocation.

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

Parameters4/5

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

Schema description coverage is 0%, so the description carries the parameter-documentation burden. It adds meaning for all nine parameters, including state values, author filtering, and repo format. However, it marks repo as 'required' while the schema allows null/default, and several platform-level parameters like project_ref and connector_account_ref are described too vaguely and opaquely.

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 opening line 'List pull requests for a repo' uses a specific verb and resource, and the state/author filters further clarify the scope. This clearly differentiates it from sibling tools like github_list_issues, github_get_pull_request, and github_list_pull_request_files.

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 guidance is provided about when to use this tool versus alternatives. The description does not mention github_get_pull_request for a single PR, github_list_pull_request_files for changed files, or github_list_issues for issues, and it gives no exclusions or prerequisites.

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