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

With no annotations, the description does carry useful weight: it declares this is a real provider-side write and that confirm=true is a mandatory gate, which tells the agent the mutation is externally visible. It omits what an agent still needs for a mutation — required permissions/account authorization, whether the effect is reversible, rate limits, and what a successful response looks like.

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, zero filler, with the core action front-loaded and the safety constraint immediately after. Nothing in it is redundant or padded.

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 write tool with no annotations, no output schema, and zero schema descriptions, the description covers the two things that most affect safe invocation (it's a real write; confirm is required). It leaves gaps on identifier formats, which account context is needed, and the effect/timeout semantics, so it is adequate rather than complete.

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% across 5 parameters, so the description must carry the load and largely doesn't. It conveys the meaning of is_paused (pause vs resume) and reiterates the confirm=true constraint, but ad_id (string or integer, format unstated), account_id, and timeout_ms get no explanation whatsoever.

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 gives a specific verb+resource ('Pause or resume one Telegram Ads ad') with an explicit scope of a single ad, which cleanly separates it from siblings like ads_telegram_ads_api_increase_ad_budget or ads_telegram_ads_api_create_ad. It does not name those siblings, so it stops short of a 5.

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?

Usage is only implied: an agent can infer it should call this when it wants to toggle an ad's active state. There is no statement of when not to use it, no mention of the sibling write tools (budget increase, submit for review), and no prerequisites beyond the confirm requirement.

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