bale_mark_chat_read

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

No annotations are provided, so the description carries the full behavioral burden. It discloses the bulk nature ('all messages'), but says nothing about side effects such as read receipts being sent to other participants, whether unread counters are reset, or what happens if no unread messages exist.

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, well-formed sentence with the action and scope front-loaded and zero filler. It is efficient, though the terseness partly reflects the missing guidance rather than deliberate compression.

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?

An output schema exists so return values need not be explained, and the operation is simple, but with no annotations and 0% schema coverage the definition leaves an agent without the auth/session preconditions or the chat_type vocabulary needed to invoke it reliably.

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% for both parameters. The phrase 'chat or group' loosely hints that chat_type distinguishes private chats from groups, but chat_id format, valid chat_type values, and the default semantics ('private' when omitted) are documented nowhere.

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?

States a specific verb ('Mark ... as read') and resource ('all messages in a chat or group'), with the scope 'all' made explicit. No sibling tool performs read-marking, so differentiation is implicit, but the action and target are unambiguous.

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 guidance on when to call this versus alternatives, no prerequisite (e.g. requires an active authenticated session), and no note on whether it applies to a single dialog only. Usage must be inferred entirely from the name and description.

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