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

Annotations already declare readOnlyHint=false, destructiveHint=false and openWorldHint=false, so the mutation profile is known. The description is consistent with them but adds nothing behavioral beyond the field list, which is itself already in the schema; it does not say whether unspecified fields are preserved or what a no-op looks like.

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 no filler, which is the right size for this operation. It earns slightly less than full marks because the enumerated fields largely duplicate the schema rather than adding new information.

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 mutation tool with no output schema and adequate annotations, the definition is minimally viable but omits useful context: which fields are optional versus required, that only supplied fields change, and any permission requirement for editing a project.

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 83%, so the schema already carries the parameter burden (including the status enum). The description merely echoes the updatable field names and does not add format, idempotency, or partial-update semantics for the six parameters.

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 (Change) and resource (a project's title, summary, status or link), so the agent knows exactly what is being mutated. It does not differentiate itself from nearby siblings such as post_project_update or update_my_profile, which leaves selection to the agent's judgment.

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 when-to-use guidance, no prerequisites (e.g. ownership of the project), and no mention of when to prefer post_project_update or add_project instead. Usage is only implied by the name and verb.

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