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

No annotations are provided, so the description carries full burden. It mentions the export action but lacks behavioral details: it doesn't specify if this is read-only or destructive, what permissions are needed, how large exports might be, or what happens on failure. The description adds minimal context beyond the basic action.

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?

The description is front-loaded with the core purpose in the first sentence, followed by a concise parameter section. Both sentences earn their place by providing essential information without fluff. Minor improvement could be integrating param details more seamlessly.

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?

Given no annotations, no output schema, and low schema coverage, the description is adequate but incomplete. It covers the purpose and parameter well, but lacks behavioral context (e.g., side effects, error handling) and output details. For a tool that exports session state, more guidance on usage and results would enhance completeness.

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%, but the description compensates well: it explicitly documents the single parameter 'session_id' with a clear explanation ('The session ID'), adding meaning beyond the schema's bare title. Since there's only one parameter, this is sufficient for high clarity, though it could note format or source.

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 clearly states the specific action ('Export full session state') and the resource ('session state') with explicit details about what's included (memory, registers, breakpoints, symbols) and the output format (JSON). It effectively distinguishes from siblings like 'import_session' (reverse operation) and 'save_context' (different scope).

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?

No guidance is provided on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an active session), compare with similar tools like 'save_context' or 'save_trace', or indicate when exporting is appropriate (e.g., for backup, sharing). The agent must infer usage from context alone.

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