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

Annotations already declare readOnly/idempotent/closed-world/non-destructive, and the description goes beyond them by disclosing the required history:read scope, the admission requirement, and that no wallet selector or signing is involved. It does not state what happens on an unadmitted request or what the response contains, which keeps it short of a 5.

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, front-loaded sentences with no filler; the core scope statement leads. The density of unexpanded domain terms ('current-store', 'storage admission') costs a point in readability, not length.

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 should say what a read returns, and it doesn't; nor does it explain the id. It does cover authorization and session constraints well, which is the harder half, so it lands as adequate-but-incomplete rather than deficient.

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 0% and the single 'id' parameter has no pattern explanation, description, or example. The prose never mentions the identifier at all, so an agent gets zero help on what the id refers to or what form it takes, leaving a real gap for a 1-param required input.

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 read operation and a scope ('Owner-private current-store read using the verified key's explicit history:read scope'), but 'current-store' and 'question privacy' are internal jargon that never resolve into a concrete resource an agent can picture. It also does not differentiate itself from the many sibling reads (history_read, history_owned_read, profile_read, history_private_jobs_detail). The verb/resource pairing is present but opaque.

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?

'Visibility, defaults and erasure require the interactive web session' is a genuine when-not rule, and 'No wallet selector or signing' + 'Storage admission is required' are preconditions. However, no sibling alternative is named for the cases this tool doesn't cover, so routing remains implied rather than explicit.

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