Load Contract Artifact

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

The description adds that the tool returns base64 and file metadata, which is beyond the readOnly and idempotent annotations. However, it does not disclose file access restrictions, error handling, or security considerations that might be relevant for a local file read operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is front-loaded with the verb 'Load' and key objects. It contains no unnecessary words and efficiently conveys purpose and output.

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

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

For a simple read-only tool with one parameter and annotations covering safety, the description is mostly complete. It specifies the output (base64 and metadata), but lacks detail on metadata structure or potential error conditions (e.g., file not found). Still adequate for most agents.

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

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

Schema coverage is 100% and the parameter description already explains the contractPath input. The tool description does not add any new meaning beyond what the schema provides, so baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it loads a local contract artifact or bytecode file and returns base64 plus metadata, using a specific verb-resource pair. It distinguishes from on-chain contract tools like genlayer_get_contract_code or genlayer_call_contract.

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

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

The description mentions 'for downstream GenLayer workflows' implying use context but provides no explicit guidance on when to use this tool vs siblings (e.g., when to load local artifact vs fetch on-chain contract code). No exclusions or alternatives are given.

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