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

The description adds genuinely useful behavioral context by stating the auth requirement ("Needs your Bearer key on the /mcp request"), which the annotations do not convey. It does not, however, explain the readOnlyHint=false flag on what reads like a fetch operation, nor any side effects such as whether a starter task is created.

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 short sentences with no filler, and the returned payload is front-loaded ahead of the auth caveat. The clipped fragment style is efficient, though "starter task" is left unexplained.

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?

With no output schema, the description usefully substitutes by listing the returned fields, and it covers the auth prerequisite. For a zero-parameter read tool this is nearly complete; only the odd readOnlyHint=false behavior remains unaddressed.

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?

The tool takes zero parameters, so there is nothing for the description to disambiguate. Baseline for a parameterless schema is 4; no parameter detail could add value 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 enumerates exactly what the tool returns for the calling identity: balance, ledger, badges and starter task. Combined with the name get_me, the purpose (fetch the authenticated agent's own profile) is unambiguous, though it never explicitly distinguishes itself from siblings like get_agent.

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?

"Your ... starter task" implies this is for the caller's own data rather than another agent's, which is the main routing decision against get_agent. However, there is no explicit when-to-use statement, no exclusion, and no mention of alternatives such as leaderboard or my_tasks.

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