list_commit_statuses

Retrieve commit statuses for a specific branch, tag, or SHA to monitor build results, test outcomes, and deployment states in GitHub repositories.

Instructions

List commit statuses for a reference (branch, tag, or SHA).

Behavior2/5

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

No annotations are provided, so the description carries full burden. It states it's a list operation, implying read-only behavior, but doesn't disclose pagination details (implied by parameters), rate limits, authentication needs, or what the output contains. For a tool with no annotations, this is a significant gap in behavioral context.

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?

The description is a single, efficient sentence that directly states the tool's purpose without unnecessary words. It's front-loaded with the core action and resource, making it easy to parse. Every part of the sentence contributes essential information.

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?

Given the tool's moderate complexity (5 parameters, 3 required), 100% schema coverage, and the presence of an output schema, the description is minimally adequate. However, with no annotations, it lacks behavioral details like pagination behavior or error handling, which could be helpful despite the output schema. It meets basic needs but has clear gaps.

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 parameters are well-documented in the schema. The description adds minimal value by clarifying that 'ref' includes 'branch, tag, or SHA', but this is already covered in the schema's description for 'ref'. No additional semantics beyond the schema are provided, meeting the baseline of 3.

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 action ('List') and resource ('commit statuses') with the target ('for a reference'). It distinguishes from siblings like 'list_commits' or 'list_check_runs' by specifying statuses rather than commits or checks. However, it doesn't explicitly differentiate from all possible similar tools, keeping it at 4 instead of 5.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention sibling tools like 'get_commit' or 'list_check_runs' that might overlap in functionality, nor does it specify prerequisites or exclusions. This leaves the agent without context for tool selection.

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