save_project

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

With no annotations, the description carries the full burden and does well: it discloses that a backup is created before in-place saving and that overwriting the original requires an explicit confirmation flag, signaling the destructive path. It does not mention failure modes, return values, or prerequisites such as a currently open project, leaving some behavioral gaps.

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?

Three sentences, zero filler, front-loaded with the core action and then the mode-specific requirements in priority order.

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 3-parameter, no-output-schema tool with no annotations, the description covers the operation modes and the safety gate adequately. Minor omissions remain around error behavior and whether the project must already be open.

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%, so 3 is the baseline, but the description adds the inter-parameter relationship the schema only states per-field: confirm_overwrite is required specifically when saving in-place without save_as_path. That is meaningful semantics beyond the individual field docs.

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?

States a specific verb and resource ('save the current Premiere Pro 2019 project') and immediately enumerates the three distinct modes of operation. No sibling tool in the list performs saving, so the agent can place it unambiguously.

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 states the conditions that select each mode: save_as_path for saving a copy, create_backup for a timestamped backup, confirm_overwrite=true for in-place overwrite. There is no explicit when-not-to-use guidance, but for an isolated save operation the routing conditions are clear.

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