Update Profile

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

Annotations already signal a non-read-only, non-destructive, idempotent mutation; the description adds that it returns a confirmation and constrains allowed values. It does not explain whether omitted optional parameters are preserved or overwritten, which is a meaningful behavioral gap for a profile-update tool.

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 clearly organized with intro, Args, Returns, and Tips, and it front-loads the purpose. It is a bit longer than strictly necessary because the Args section duplicates schema constraints, but the structure keeps it scannable.

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 six-parameter mutation tool with no output schema, the description provides the essential inputs, return confirmation, and some usage tips. It misses the semantics of partial updates and prerequisites, so an agent may still be uncertain about the tool's full behavior.

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 the baseline applies; the description repeats the constraints (10-100 chars, 1-15 skills, 0-80 hours) but adds no conceptual meaning beyond the schema. It also doesn't explain cross-field relationships such as whether availability and hours_per_week must be consistent.

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 opens with the concrete action 'Update your Upwork freelancer profile' and enumerates the exact fields (title, overview, hourly rate, skills, availability). This makes it immediately distinguishable from sibling tools like upwork_get_profile or upwork_update_proposal.

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?

It implies the trigger condition by saying 'Modify your professional title, overview, hourly rate, skills, or availability,' so an agent can infer when to call it. However, it never explicitly names alternatives (e.g., use upwork_get_profile to read first) or states exclusions/prerequisites such as needing an existing profile.

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