artifact_get

Retrieve a single sprint artifact by ID to inspect its stored content and context. Use it when you need details from a specific artifact.

Instructions

Read one artifact by id.

TDQS

C2.6/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full behavioral burden. 'Read' implies a safe read-only operation, but the description does not disclose authentication needs, claim requirements, error behavior, or what happens when the artifact is missing.

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 single sentence is front-loaded and free of waste, but it is undersized for a tool with five parameters and no annotations. Brevity here reflects missing information rather than optimal concision.

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

Completeness2/5

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

Given five parameters, zero schema description coverage, no annotations, and no output schema, the description is too sparse. It establishes the basic read operation but leaves most calling context undocumented.

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%, and five parameters are present. The description clarifies only the required id parameter ('by id') and says nothing about agent_token, client_agent_id, claim_generation, or client_session_id.

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 states a specific verb and resource: 'Read one artifact by id.' This clearly distinguishes the tool from artifact_list and artifact_update, though it does not explicitly name those siblings or explain the distinction.

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 gives no explicit guidance on when to use this tool versus artifact_list, artifact_update, or artifact_add. The 'by id' phrasing implies retrieval when an identifier is known, but the agent must infer usage conditions.

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