setMyDefaultAdministratorRights

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

No annotations exist, so the description carries the disclosure burden. It does disclose the mutating effect, the timing (applies at admin-add time), and the return value ('Returns True on success'), which is valuable given there is no output schema. Notable gaps: it does not state that omitting 'rights' clears defaults (left to the schema) or that existing admin memberships are unaffected by the change.

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 short sentences with zero filler: the core action leads the description and the return value is stated separately. Every sentence earns its place.

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 a rich 100%-covered nested schema and no output schema, the description covers the high-level behavior plus the return value, which is mostly sufficient for correct invocation. Minor gap: it never routes the agent to getMyDefaultAdministratorRights or notes that this is a global bot-level setting distinct from per-chat promotion calls.

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% — both 'rights' (including the clear-when-omitted behavior) and 'for_channels' are fully documented in the schema. The tool description adds no parameter-level information beyond the schema, so the baseline of 3 applies.

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 uses a specific verb ('Change') and a precise resource ('default administrator rights requested when adding the bot as administrator to groups or channels'). This scope self-evidently distinguishes it from the sibling getter getMyDefaultAdministratorRights (set vs get) and from per-member admin tools like promoteChatMember or setChatAdministratorCustomTitle.

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 phrase 'requested when adding the bot as administrator to groups or channels' implies the scenario in which the setting applies (future admin additions, not per-chat moderation), giving the agent usable context. However, there is no explicit when-to-use/when-not-to-use guidance and no reference to the sibling getMyDefaultAdministratorRights for verifying current defaults.

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