project_set_title

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

With no annotations, the description carries the full burden. It usefully discloses the side effect that the export filename changes, but omits whether the rename persists automatically, whether project_save_local is required, and whether it is undoable. Some behavioral value, but significant gaps remain.

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?

A single front-loaded sentence with zero waste. The effect of the operation is stated immediately with no filler.

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 single-parameter setter with no output schema and no annotations, the description covers the visible effect adequately but leaves open whether the change is persisted and how it relates to save/undo tools. Complete enough to invoke, not complete enough to predict state.

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 single 'title' parameter is already documented with an example in the schema. The description adds the fact that it becomes the navbar/export name, which is marginal value beyond the structured field. Baseline 3.

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 ('Renames') and resource ('active project title'), and even identifies the visible effects (top navbar, export filename). It does not explicitly distinguish itself from siblings, but no sibling competes for the same rename-title role, so an agent can identify it correctly.

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?

There is no guidance on when to use this tool versus related ones (e.g., project_save_local, history_undo). Usage is only implied by the phrase 'Renames the active project title'; no prerequisites, exclusions, or alternatives are stated.

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