github_list_deployments

Read-onlyIdempotent

List deployments from a GitHub repository, optionally filtered by environment, providing release IDs, SHAs, and timestamps.

Instructions

Read one bounded page (30) of deployments for one exact GitHub repository, optionally for one environment, as release records: id, sha, ref, environment, task, and timestamps.

Args: owner (required): Repository owner login. repo (required): Repository name. environment: Optional deployment environment name. per_page (required): Page size; the governed contract requires 30. 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.

TDQS

A4.1/5.0
Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior. The description adds meaningful behavioral context: page size is contractually bounded to 30, the 'effect' parameter must be 'read' and is verified by Spring, and approval_ref applies when resuming a write. These details go beyond the annotations without contradicting them.

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 overview sentence is crisp and front-loaded with the essential behavior, followed by a structured argument list. Some boilerplate governance parameters add length but are each given a compact, useful gloss. No redundant prose.

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?

For a read-only list tool with an output schema, the description covers the operation, key constraints (page size, exact repo, optional environment), and all parameters. It does not detail pagination beyond 'one page' or error/rate-limit behavior, but those are not critical given the annotations and output schema.

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?

With schema description coverage at 0%, the description fully compensates by explaining each parameter's role, including governance fields like project_id, project_ref, and idempotency_key. However, there are minor inconsistencies: owner/repo/per_page are labeled 'required' while the schema only marks effect as required, and per_page has a default. Still, the descriptions add useful meaning beyond the raw schema.

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 description opens with a specific verb ('Read') and resource ('deployments'), and precisely scopes the operation: one bounded page (30) for one exact repository, optionally filtered by environment. It also lists the returned fields, making the tool's purpose unambiguous and distinct from other GitHub tools.

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

Usage Guidelines3/5

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

The description implies when to use the tool (reading deployment records for a specific repo, one page at a time, optional environment filter) but does not explicitly state alternatives or exclusions. An agent must infer that this is for bounded single-page reads and that other tools handle creation, statuses, or pagination.

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