setChatPermissions

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

With no annotations provided, the description carries the full behavioral burden. It discloses that the operation modifies default chat permissions for all members, requires administrator rights, and returns True on success. It does not cover failure modes or potential side effects, but the key behavioral traits are present.

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 two concise sentences with no filler. The primary action and scope are front-loaded, followed by prerequisites and return value.

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 rich nested schema and simple boolean return, the description covers the essential operational context: what the method does, what rights are needed, and what success returns. It could mention failure behavior or warn about replacing all default permissions, but it is largely complete for an API method.

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 100%, so all parameters are already documented in the schema. The description adds no additional param-level meaning beyond restating that permissions are default chat permissions, which is also evident from the tool name.

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 states a specific action, resource, and scope: setting default chat permissions for all members. This clearly distinguishes it from sibling tools like restrictChatMember, which target individual members rather than defaults.

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 gives a clear context for use: setting default permissions for all members. It also states a necessary precondition (administrator with can_restrict_members rights). It does not explicitly name alternatives or state when not to use the tool, but the scope is clear enough.

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