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

The annotations already declare readOnlyHint=false and destructiveHint=false, so the agent knows this is a non-destructive mutation. The description adds that the file is a user-attached ChatGPT file and that the target may be an existing work package or wiki page, but it does not disclose permission requirements, overwrite behavior, or target-specific constraints.

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 front-loaded sentence with no wasted words. It efficiently communicates the source object and the three target categories.

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?

This is a six-parameter mutation tool with a nested file object and no schema parameter descriptions. Although an output schema exists, the description leaves key invocation details unexplained, such as when target_id is required and how project_id relates to each target type.

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 description coverage is 0%, so the description must carry the burden of explaining six parameters. It partially maps target_type by naming document, work package, and wiki page targets, but it does not explain project_id, target_id, title, description, or the nested file object fields.

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 gives a specific verb and resource: upload a user-attached ChatGPT file. It also clarifies the three possible targets, but it does not explicitly distinguish this tool from sibling creation tools such as openproject_create_work_package or openproject_create_wiki_page.

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 implies usage by listing the allowed target types: project document, existing work package, or wiki page. However, it does not state when to choose each target, what prerequisites are needed, or why an agent should use this tool instead of creating a document through another path.

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