imgui_save_snapshot

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

No annotations are provided, so the description carries the burden. It implies persistence of state but doesn't disclose whether this writes to disk, whether it clobbers an existing snapshot with the same name, or what happens on error. Basic intent is disclosed but consequences of the operation are under-specified for a state-mutation tool.

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?

Two sentences, zero waste. States the action, the resource, and points to the complementary restoration tool. Efficient and front-loaded.

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?

For a single-parameter tool with a self-documenting schema, the description is largely sufficient. However, it doesn't clarify overwrite semantics for duplicate names, whether snapshots are volatile or persisted, or any potential failure modes. Given the mutation nature and lack of annotations/output schema, a bit more behavioral context would improve 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 coverage is 100% — the only parameter 'name' is documented in the schema with its default 'snapshot_N.' The description adds context by explaining the name identifies a restorable snapshot. With full schema coverage and a single self-explanatory optional parameter, the baseline holds; marginal extra meaning is provided.

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?

Description states a clear verb+resource: 'Save the current layout state as a named snapshot.' It distinguishes from siblings by referencing the complementary imgui_load_snapshot, but doesn't compare against the closely related imgui_list_snapshots/delete_snapshot. Clear and functional purpose.

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 description notes snapshots 'can be restored later with imgui_load_snapshot,' conveying a save/restore workflow. However, it doesn't state when to use this vs delete_snapshot or list_snapshots, nor does it mention any constraints (e.g., naming rules, limit on snapshots, whether this persists across sessions). Adequate but not thorough.

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