edb_compare_snapshot

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

The description states 'save' and 'for later comparison' but does not disclose storage details, side effects, or limitations. Annotations provide readOnlyHint=false and destructiveHint=false, but the description adds little beyond that. It fails to mention whether snapshots are stored in memory, disk, or temporary, or if there is a limit.

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 a single sentence of 9 words, efficiently stating the action and purpose. Every word contributes meaning without redundancy.

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 the presence of many sibling snapshot and state tools, the description lacks crucial details on how the snapshot is used for later comparison, what the output contains, and the role of the label parameter. Though simple, it omits expected context.

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 one parameter 'label' has a description in the schema ('Snapshot label (default: auto timestamp)'). The tool description does not mention the parameter, so schema coverage is effectively provided by the schema itself. The description adds no additional meaning, earning the baseline score of 3.

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 'Save a full debugger snapshot (registers + memory) for later comparison.' It specifies the verb, resource, and purpose. However, the tool name 'edb_compare_snapshot' could imply comparison, while the description says save, causing minor confusion.

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. Among many sibling tools for saving state (e.g., edb_export_state, edb_dump_state), there is no differentiation or context for choosing this snapshot save.

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