update_profile_projects

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

No annotations are provided, so the description carries the full behavioral burden, yet it only says 'Update'. It does not disclose whether the projects array replaces the entire existing list or merges/appends, whether the operation is destructive, what permissions are required, or anything about the result. For a list-of-objects mutation, replacement semantics are critical and undisclosed.

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 short sentence is well-front-loaded and free of filler, but its brevity reflects under-specification rather than disciplined conciseness. There is no wasted text, yet also no useful payload.

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 annotations and no output schema, the description should at minimum explain replace-vs-merge behavior and any auth requirements. Neither is present, leaving a meaningful gap for an agent attempting a correct invocation.

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 100%, and the nested project object fields (url, name, description, technologies) are documented in the schema. The description adds no meaning beyond the schema and, importantly, does not clarify whether the array is a full replacement or a partial update. Baseline 3 applies when the schema does the heavy lifting.

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 states a verb (Update) and resource (user's projects), which is marginally more than the tool name itself. However, it is nearly a tautology of 'update_profile_projects' and offers no differentiation from the many sibling profile mutators (update_profile_skills, update_profile_education, update_profile_employment). An agent gets no more information than it could infer from the name.

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 update_full_profile or the other granular profile updaters, nor any prerequisite or context. The agent must infer usage purely from the name.

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