artifact_search_binaries

Search Nexus or Artifactory for components and binaries by name, repo, version, or SHA256. Get download URLs, versions, timestamps, checksums to locate release artifacts or verify build presence.

Instructions

Search components and artifacts across Nexus or Artifactory.

Returns download URLs, exact versions, creation/modification timestamps, and SHA256/SHA1/MD5 checksums.

Purpose: Locate specific binaries or verify build component presence. When to Use: To locate release artifacts before deployment or check artifact metadata. Behavior: Read-Only search. Side Effects: None.

Args: name: Artifact or component name (supports wildcards/substrings, e.g. 'order-service') group_or_repo: Repository name or Maven groupId (e.g. 'libs-release-local' or 'com.myorg') version: Specific version string (e.g. '1.4.2' or '2.0.0-SNAPSHOT') sha256: Exact 64-character SHA256 checksum to look up session_name: Session to query (default: 'default')

A4.5/5.0
Behavior4/5

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

With no annotations provided, the description carries the full burden and does well: it declares 'Read-Only search' and 'Side Effects: None,' and lists returned metadata including URLs, versions, timestamps, and checksums. It does not mention permission requirements, session behavior, or rate limits, leaving minor gaps.

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 front-loaded and organized into Purpose, When to Use, Behavior, Side Effects, and Args. There is mild redundancy between Purpose/When to Use and between Behavior/Side Effects, but it remains efficient.

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

Completeness5/5

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

Given five parameters, 0% schema description coverage, and no annotations, the description provides the missing behavioral and parameter context. It also describes return values even though an output schema exists, making the tool callable without further inference.

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

Parameters5/5

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

Schema description coverage is 0%, but the description compensates fully. It explains each of the five parameters with examples and constraints: name supports wildcards/substrings, group_or_repo can be a repository or Maven groupId, version format is shown, sha256 is an exact 64-character checksum, and session_name has a default.

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 states a specific verb and resource: search components/artifacts across Nexus or Artifactory. It also names the returned data (URLs, versions, timestamps, checksums), which distinguishes it from sibling tools like artifact_list_repositories, artifact_verify_checksum_integrity, and artifact_get_docker_image_tags_and_digests.

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

Usage Guidelines4/5

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

It clearly says when to use the tool: locating release artifacts before deployment or checking artifact metadata. However, it does not explicitly state when not to use it or name a sibling alternative for overlapping tasks such as checksum verification.

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