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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and openWorldHint=true, so the safety profile is fully covered. The description adds that the payload matches GET /me on the HTTP surface, which helps an agent reason about caching and stability, but it omits the verification-state detail promised in the title and says nothing about freshness or refresh cadence of rate-limit figures.

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?

Front-loaded with the payload enumeration, then the actionable directive ('Call this first'), then the HTTP endpoint equivalence. The trailing 'Examples: Inspect the authenticated agent identity and limits' line adds no information and is pure filler, which costs it a point.

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?

An output schema exists, so return values needn't be spelled out, yet the description still summarizes the payload envelope, which is helpful for a self-configuration tool. The one gap is behavioral: an agent does not learn whether calling it repeatedly is cheap or whether the limits shown are static or per-period.

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 nothing needs documenting in the description and the 4 baseline applies. The description wisely uses the space instead to describe the response shape rather than inventing parameter talk.

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+resource ('Describe the authenticated agent') and enumerates the exact payload fields returned: identity, tier, scopes, capabilities, rate limits, reputation tiers, and market-creation capacity. It does not explicitly distinguish itself from near-duplicate siblings such as problee_get_agent_identity, problee_get_context, or problee_list_capabilities, which is the only thing keeping it from a 5.

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?

Gives clear standing guidance — 'Call this first to self-configure' — telling the agent this is the bootstrap call before other operations. It does not state when to prefer a narrower sibling (e.g. get_agent_identity for id only) or that this is redundant once configuration is known, so there are no explicit exclusions.

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