discord_get_current_channel

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

With no annotations at all, the description carries the full disclosure burden. It implies a read-only lookup via 'Get' but says nothing about what happens when no channel is selected, whether DMs/threads are included, or what the response contains — all material for a zero-argument tool whose entire input is client state.

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 front-loaded sentence with no filler; the scoping qualifier ('currently open / selected in your Discord client') arrives before anything else could be needed.

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?

The minimal schema is fully covered, but with no output schema and no annotations, the description would need to define what 'details' includes and what an empty/no-selection result looks like. As written it is callable but leaves the agent guessing about the return shape.

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 tool takes zero parameters, so there is nothing for the description to disambiguate and the baseline applies. The description appropriately spends its words on scope rather than inventing parameter detail.

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?

Specific verb ('Get') and resource ('the channel currently open / selected in your Discord client'), which cleanly separates it from ID-based siblings like discord_get_channel_info and from discord_get_current_guild. It stops short of 5 because 'details' is left unspecified and no sibling is named explicitly.

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 'currently open / selected' framing implies the use case (acting on the user's active context rather than an arbitrary channel), but there is no explicit when-to-use, no exclusion, and no pointer to the alternative tool for fetching an arbitrary channel by ID.

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