gadgets_read_events

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

With no annotations, the description must carry the behavioral burden, and it does disclose two non-obvious traits: results are bounded and ordered, and a null cursor signals explicit history loss. It still omits pagination semantics (how to advance the cursor), permission requirements, and what the returned events contain.

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 tight sentence with the core purpose front-loaded and no filler. It is arguably too terse for the domain, but nothing in it is wasted.

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 cursor-paginated read tool with three undocumented parameters, no annotations, and no output schema, the definition leaves too much unspecified. An agent cannot determine how to page, what device_id does, or what happens when the history-loss path triggers.

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 all three parameters (limit, cursor, device_id) are undocumented in the schema. The description partially compensates by explaining the null-cursor case and implying bounding via 'limit', but device_id and cursor advancement are never addressed.

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 specific verb and resource ('Read ... event history') with two qualifiers ('bounded', 'ordered'), which separates it reasonably well from siblings like gadgets_get_state and gadgets_diagnostics. It is not a tautology, but it never says what an 'event' is or how this differs concretely from reading state.

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?

There is no when-to-use guidance and no mention of alternatives among the five sibling tools. The only usage-adjacent statement is the cursor=null behavior, which is a mechanism rather than a selection rule.

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