sync_telegram

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

Description discloses core behavior: uses getUpdates, syncs since last sync, requires token, and filters by chat_id. However, it lacks details on side effects (e.g., memory updates, deduplication), idempotency, error handling, or rate limits. Without annotations, the description carries the burden but covers only essential mechanics.

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?

Description is structured with a clear purpose line, technical details, and an argument section. It is reasonably concise but could tighten the arg description into fewer sentences. No wasted words.

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 no output schema and no annotations, the description explains the tool's operation and parameter adequately but misses output behavior or return value. It does not mention what the tool returns (e.g., count of synced messages) or error scenarios. Sibling tools might have similar gaps, but for a mutating sync tool, more completeness would help.

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?

The description adds significant meaning beyond the schema: explains chat_id sign convention (positive DM, negative group), default behavior (syncs all chats if omitted), and environment variable fallback (TELEGRAM_CHAT_ID). Schema coverage is 0%, so this full explanation compensates completely.

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?

Description clearly states 'Sync new Telegram messages received by the bot into memory,' providing a specific verb (sync), resource (Telegram messages), and scope (new messages received by bot). It distinguishes from siblings like sync_discord by explicitly naming Telegram and the bot-specific nature.

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?

No explicit guidance on when to use this tool vs alternatives (e.g., import_telegram, other sync tools). It mentions a prerequisite (TELEGRAM_BOT_TOKEN) but does not specify exclusion criteria or recommend alternatives for different use cases.

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