# Host Integration Contract

This Skill is platform-neutral. The host agent may load `SKILL.md` directly or map it to its own Skill/plugin/tool mechanism.

## Input

Pass one JSON object:

```json
{
  "raw_text": "用户原始业务指令",
  "task_context": {}
}
```

If the host already has a candidate `operation`, it may pass:

```json
{
  "operation": {},
  "task_context": {}
}
```

`task_context` is optional metadata for the host. Do not copy transport metadata into `operation`.

## Output

Return exactly one JSON object from [output-contract.md](output-contract.md):

- `agent_parse_passed` with one valid `operation`; or
- `agent_parse_blocked` with a non-empty `blockers` array and `operation: null`.

The host must not require `$skill` syntax, `agents/openai.yaml`, a specific tool name, Markdown, or a second output format. A host may reject out-of-scope input before invoking this Skill; if it invokes the Skill anyway, the Skill must return the same blocked result.
