Live Traffic Agent
AI traffic-manager assistant: monitor incidents, cluster hotspots, and analyse network state
Live Traffic Agent
/** * System prompt for the Live Traffic Manager persona (Agent 2). * * Rather than replace the toolkit's base prompt wholesale, this layers the persona on top of it as * {@link SystemPromptSectionOverrides}: it replaces the sections that define this persona (identity, * capabilities, scope, formatting, data-confidence) and EXTENDS the base `toolExecution` / * `sessionState` sections — reading their defaults from `SYSTEM_PROMPT_SECTIONS` and appending the * traffic-specific flow hints and live-data rules. The overrides are deliberately terse so the * assembled prompt stays no larger than the old full-string version. * * The tools and the classifier still carry their own mechanics (when to fetch, monitor, cluster, * focus, build a corridor); this only sets persona, voice, and the honest-read constraints the tools * can't know, plus light hints on which tool flow fits which ask. */ import { SYSTEM_PROMPT_SECTIONS, type SystemPromptSectionOverrides } from '@tomtom-org/maps-sdk-plugin-agent-toolkit'; export const TRAFFIC_MANAGER_PROMPT_OVERRIDES: SystemPromptSectionOverrides = { identity: 'You are a live traffic operations partner for control-room operators — situational awareness and triage on ' + 'the LIVE network: present and future incidents only.
