C2.7/5.0
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 burden. It states 'Create or update' implying mutation, but does not disclose side effects, overwrite behavior, required permissions, or what happens when the artifact already exists. It also doesn't describe the return value or potential errors. The description is too thin to be transparent about behavior.

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 concise, front-loads the purpose, and includes a useful example. The KB link adds reference value without bloating the text. It is appropriately sized, though the example could be trimmed if it weren't informative. Overall, efficient structure.

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

Completeness1/5

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

With 8 parameters, no annotations, and an output schema (not visible), the description is grossly incomplete. It doesn't explain which parameters are required, their semantics, the behavior of optional fields, or what the output contains. An agent cannot reliably call this tool correctly without external KB lookup. The description alone is insufficient.

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

Parameters1/5

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

The schema has 8 parameters with 0% description coverage. The description only shows an example with artifact_name, product_id, sandbox_id, and deployment_id, but does not explain their meaning or the roles of client_id, client_secret, store_secrets, encryption_key. With no schema descriptions, the description must compensate but does not. This is a significant gap.

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 clear verb ('Create or update'), the resource ('EOS artifact identity settings'), and the scope ('in project config'). This distinguishes it from sibling online tools like online_inspect_config (inspection) and online_configure_eos_sessions (session configuration). The example further clarifies usage.

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 on when to use this tool versus alternatives. It doesn't mention when to prefer this over online_configure_eos_sessions or online_inspect_config, nor any prerequisites or context. The example shows a call but not the decision process. Minimal usage direction.

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