session_status

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

With no annotations provided, the description carries the full behavioral burden. 'Check' implies a read-only probe, but it never confirms side-effect-free behavior, permissions/auth needs, or cost, and gives no hint about what 'loaded' versus 'not loaded' states mean in practice.

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?

A single short sentence with the scope qualifier front-loaded at the end of the clause; nothing is wasted. It is perhaps too terse rather than verbose, but structurally clean.

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 need not be explained, but for a tool whose only argument is ambiguous against its own 'this session only' framing, the description does not resolve the tension. The semantics of the loaded/unloaded state and the role of session_id are both left for the agent to infer.

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%, so nothing documents the single session_id parameter, which has a default of '' and is not required. The description's 'this session only' actively muddies this: it is unclear whether session_id selects another session or whether an empty value means the current one.

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 concrete verb ('Check') and a concrete target ('the memory-loaded state of this session'), which is more specific than a restatement of the name. The phrase 'this session only' begins to differentiate it from siblings such as get_session_handoff or list_recent_sessions, though what 'memory-loaded state' actually means is left implicit.

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?

The word 'only' hints at a scope restriction, but no sibling is named as the alternative for checking other sessions, and no when-to-use/when-not-to-use conditions are stated. An agent must guess whether get_session_handoff, list_recent_sessions, or query_memory is the right call for a non-current session.

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