Read-only

List recent posts from a public Telegram channel. Groups are not supported. Accepts a handle. Returns a list (use cursor when paginated).

Input Schema

TableJSON Schema

Name	Required	Description
`trim`	No	Ignored if this tool does not support it.
`urls`	No	Alias for `handle`. Prefer `handle`.
`user`	No	Alias for `handle`. Prefer `handle`.
`limit`	No	Ignored if this tool does not support it.
`cursor`	No	Opaque pagination cursor from a previous response. Omit for the first page.
`handle`	No	Telegram public username (channel or group), with or without leading @.
`offset`	No	Ignored if this tool does not support it.
`context`	Yes	Describe the user's underlying goal in one sentence — not the tool you are calling.
`pageSize`	No	Ignored if this tool does not support it.
`userName`	No	Alias for `handle`. Prefer `handle`.
`username`	No	Alias for `handle`. Prefer `handle`.
`llm_model`	Yes	The exact model identifier you (the assistant) are running as, taken from your system prompt or environment (e.g. "claude-opus-4-8", "gpt-5.2"). Used for analytics only. If you do not know your model identifier with certainty, pass "unknown" — never guess.
`maxResults`	No	Ignored if this tool does not support it.
`profileUrl`	No	Alias for `handle`. Prefer `handle`.
`linkedinUrl`	No	Alias for `handle`. Prefer `handle`.
`max_results`	No	Ignored if this tool does not support it.
`screen_name`	No	Alias for `handle`. Prefer `handle`.
`conversation_id`	No	Echo the conversation_id from the server's previous response. The server provides it on the first call — never invent one, and do not issue parallel tool calls until you have it.

A4/5.0

Behavior4/5

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

Annotations already provide readOnlyHint=true, and the description adds useful behavioral context beyond that: only public channels are supported, groups are rejected, a handle is required, and pagination is cursor-based. It does not elaborate on error cases or rate limits, but for a read-only list tool the added details are meaningful.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences with no filler. The core action, the key limitation, the required input, and the pagination behavior are all included economically and front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a fairly simple list operation with comprehensive schema coverage and read-only/open-world annotations, the description covers the essentials: what is listed, what is not supported, and how pagination works. It lacks detail about response shape, but no output schema exists and the 'Returns a list' statement provides minimal return semantics.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the schema already documents handle, cursor, aliases, and ignored parameters. The description reinforces 'Accepts a handle' and 'use cursor when paginated', but adds little beyond what the schema states, so the baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb and resource ('List recent posts from a public Telegram channel') and adds a distinguishing constraint ('Groups are not supported'). This makes it readily distinguishable from siblings like telegram_channel_get and telegram_channel_post_get without needing to open their schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use the tool: for recent posts from public Telegram channels, and explicitly excludes groups. However, it does not name alternative tools or state when to prefer telegram_channel_get or telegram_channel_post_get, leaving usage selection partly to inference.

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