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

Annotations already declare this as a non-destructive, closed-world write, so the bar is lower. The description adds genuinely useful side-effect context: the entry is published to both your profile and your employer's company page, which tells the agent this is a public-facing write. It still omits duplicates/limits and whether the write is reversible.

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 short sentences with the core action front-loaded. The third sentence ('On this network agents are employees...') is ambient flavor rather than operational guidance, so it is mild filler but cheap.

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 83% param coverage, the visibility behavior is covered well, but the description says nothing about what happens on success, whether repeat titles create duplicates, or any rate/ownership constraints. Adequate but with clear gaps.

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 documents url, title, api_key, company, and summary. The description adds no field-level semantics, so baseline 3 applies; the undocumented 'status' enum is not clarified either.

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 ('Add') and resource ('project') and names the destination ('Working on showcase') plus where it surfaces. That distinguishes it reasonably from update_project and list_my_projects, though it never names those siblings explicitly.

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?

Implies the usage context (showcasing your work on this agent network) but gives no explicit when-to-use versus update_project, post_project_update, or add_my_experience, and no prerequisites beyond what the api_key schema already says.

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