# travel agents

Use this skill when the user wants an AI Agent to "travel for me" and maintain a multi-day journey along a route.

This is a portable coding-agent skill for UI and CLI hosts. Work through local files and scripts.

## Capability Adapters

Different coding agents expose different capabilities: native image generation, weather/search, reminders/automation, browser tools, or local command execution. Select the available adapter at run time and keep trip state portable across hosts.

Supported adapter categories:

- Native image tool adapter: call the host agent's image-generation tool directly from the current turn when it is available, then update local state if the tool returns a local image path.
- API provider adapter: local scripts generate through configured API keys or command hooks.
- Automation adapter: create the daily run automation by default after a durable trip is initialized. Use host agent reminder/automation first when images require the host agent's native image tool. Use OS schedulers only when local scripts can complete image generation without the host agent through a configured local API provider or `TRAVEL_AGENTS_IMAGE_COMMAND`.
- Weather adapter: host weather/search tool first when available; otherwise use a user-provided weather summary or a configured weather command.

`detect_environment.py` cannot see host-platform automation tools. The coding agent must inspect its currently available tools before falling back to OS schedulers. In Codex, use the `automation_update` tool to create a real platform automation; do not simulate it with shell commands, cron text, or hand-written automation files.

## Image Capability Gate

This skill's core output is generated postcards. Before first-run setup, route planning, trip initialization, or daily prompt production, verify that at least one real image-generation path is available:

- A host-native image-generation tool exposed in the current agent turn.
- A configured local API provider or command hook reported by `python scripts/detect_environment.py --json` under `provider.selected_api_provider`.

If neither path is available, stop immediately and ask the user to provide one of them. Do not ask for origin, destination, Agent identity, day count, or start producing route data/prompts. This is blocking, not a degraded prompt-only mode.

Use this concise blocking response shape:

```text
我现在还不能开始这段旅程：当前 agent 没有可用的图像生成工具，本地也没有检测到可用的图片 API provider。
请先提供其中一种能力：
1. 换到带图像生成工具的 agent/环境；
2. 配置一个本地图片 provider（例如 OPENAI_API_KEY、GEMINI_API_KEY、SEEDREAM_API_KEY 或 TRAVEL_AGENTS_IMAGE_COMMAND）；
3. 直接给我一个可调用的图片生成命令。

准备好后我再开始问出发地、目的地和旅行者形象。
```

## Overview

`travel agents` turns a user's travel wish into a local, multi-day Agent journey. The agent acts as a small recurring traveler moving from an origin to a destination. For each day, the workflow chooses a waypoint, builds a scene prompt with recognizable local details, can optionally generate an image, and advances the trip state.

The route is a visually coherent, geographically plausible narrative arc for daily postcard-style scenes. The main deliverable is durable journey state, route data, daily scene prompts, and generated postcard images.

## Direct Postcard Image Requests

Use this fast path when the user explicitly asks to generate one or more postcards/images from given places, an existing route, or a supplied character reference, and does not ask to start or advance a durable trip.

This fast path is complete by itself when a host-native image-generation tool is available. Do not read `references/prompt_contract.md`, `references/route_planning.md`, `references
