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

The annotations already declare readOnlyHint=true and openWorldHint=false, so the description does not need to restate safety. It adds some context by naming the return categories, but it does not clarify default behavior, pagination, limits, or how filtering interacts with the 'all' value.

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?

One concise, front-loaded sentence states the action, resource, key returned content, and the optional filter. There is no filler or redundant phrasing.

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 one-parameter, read-only retrieval tool, the description covers what is returned and the filter option. A small gap remains: it does not explicitly state the default when 'filter' is omitted, though the 'all' enum value makes that reasonably inferable.

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 'filter' parameter already documents its enum values and meaning. The description's 'Optional filter by stack tag' essentially restates the schema without adding new semantic depth, so it earns the baseline but no more.

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 specific verb and resource: 'Get portfolio projects' with stack, highlights, and decision logs. It is clear and likely distinguishable from siblings like search_projects, though it does not explicitly name or contrast those alternatives.

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?

No guidance is provided about when to use get_projects versus search_projects or other sibling tools. There are no exclusions, prerequisites, or alternative-selection hints; the only usage hint is the optional stack-tag filter, which concerns parameter use rather than tool selection.

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