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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds one genuinely useful behavioral fact — the anonymous preview is restricted to agentanalytics-demo synthetic read-only data — but says nothing about size, caching, or how often the 'self-improving' context refreshes.

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?

Two sentences, no filler, and the payload list is front-loaded before the access caveat. The colon-separated inventory is dense but readable; nothing obviously wastes space.

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 single-parameter read tool with no output schema and annotations covering the safety profile, the description covers what is returned and who can call it. Return shape details are modestly under-described, but the conceptual contents (goals, glossary, date annotations) are listed.

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?

Only one parameter exists and schema coverage is 100% ('Project name or ID'), so the schema fully documents it. The description adds no format hints such as whether the project value is a slug, UUID, or display name, which would be the only meaningful contribution here.

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 names a specific verb and resource ('Get ... project context') and enumerates the payload — goals, activation events, event-name glossary, date annotations. It is clearly distinct from sibling mutators like set_project_context, though it never explicitly contrasts itself with list_projects or the analytics_* readers.

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?

Usage is only implied: the clause about interpreting analytics results hints you fetch this before running analytics queries, but no explicit when-to-use, when-not-to-use, or named alternative is given. The sign-in note is access guidance rather than selection guidance.

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