Token count is estimated as `characters / 4`. +6. **Return** `AssembledPrompt` with `messages[]` ready to spread into the LLM call. + +--- + +## AssemblerOptions reference + +```typescript +interface AssemblerOptions { + scope?: ConversationScope; // filter by scope (default: all) + tokenBudget?: number; // max tokens for history (default: 3000) + addressedOnlyMode?: boolean; // filter to relevant turns (default: true) + rollingSummaryThreshold?: number; // compress when turns exceed this (default: 40) + timeWindowMinutes?: number; // ignore turns older than N minutes + maxTurnsToLoad?: number; // max turns to fetch from store (default: 100) + agentAliases?: string[]; // platform bot IDs (e.g. Slack botUserId) +} +``` + +### Agent aliases + +Slack and Telegram use platform-specific user IDs for bot mentions (e.g. `U123BOT`) which differ from the agent's `name` string. Set `agentAliases` (or let `BaseAgent` auto-populate from attached channels) so `assemblePrompt` recognises those mentions: + +```typescript +agent.assemblerOptions = { + agentAliases: ['U123BOT', 'telegram-bot-456'], +}; +``` + +`BaseAgent._resolveAssemblerOptions()` auto-collects `botUserId` from channels that expose it (SlackChannel, TelegramChannel) and merges them with any manually specified aliases. + +--- + +## Addressed-only mode + +When `addressedOnlyMode: true` (the default), the assembler keeps only history turns where the agent was directly involved. This: + +- Prevents loading irrelevant multi-party chatter into the context window +- Saves tokens in busy group channels +- Keeps the LLM focused on the relevant conversation thread + +Turn `addressedOnlyMode` off only when you need full channel history — for example, a monitoring agent that analyses all traffic: + +```typescript +agent.assemblerOptions = { addressedOnlyMode: false }; +``` + +--- + +## Rolling summarisation + +When history is long, the assembler can compress older turns into a summary rather than truncating them. Provide a `SummarizerAgent` to enable this: + +```typescript +import { SummarizerAgent } from '@toolpack-sdk/agents'; + +// Create a dedicated summarizer +const summarizer = new SummarizerAgent({ apiKey: process.env.ANTHROPIC_API_KEY! }); +await summarizer._ensureToolpack(); + +// Pass it to assemblePrompt (run() does not support this yet — call assemblePrompt manually) +const assembled = await assemblePrompt( + store, conversationId, agent.name, agent.name, + { rollingSummaryThreshold: 30, tokenBudget: 3000 }, + summarizer, +); +``` + +When `rollingSummaryThreshold` is exceeded, `SummarizerAgent` receives the oldest turns and returns a compact summary. The summary is inserted as a `system` message before the recent turns. + +See [capabilities.md](capabilities.md) for the full `SummarizerAgent` API. + +--- + +## conversation_search tool + +`run()` automatically exposes a `conversation_search` tool to the LLM when a `conversationId` is active. The LLM can invoke it to retrieve specific past turns beyond the assembled context window. + +The tool is defined as: + +``` +name: conversation_search +parameters: + query: string (keywords or phrases to search for) + limit: number (max results, default 5) +``` + +**Security note**: The tool uses a closure-captured `conversationId`.
