// Echo back the agent input's session_id verbatim. Designed specifically for verifying session_id propagation through agent chains. Invoke this skill whenever a session_id is present in the agent input.
Default procurement order via ERP. Use when no substitute is available and supplier cannot expedite.
Swap to substitute material via MES. Picks the best candidate using a multi-criteria scorer (Python).
Send expedite request to supplier portal. Use only when the material's supplier has capability=expedite.
全局归档协议。只要任务需要写入任何文件（含 PLAN.md、报告、JSON 等归档物），必须按本技能执行 Session→ARCHIVE_ID、TIMESTAMP、双轨路径（根段须为 archives/）、回读校验与状态回执；WebUI 的 archive_grid 必须用 Markdown 中语言标识为 json 的围栏代码块输出。
定时计划协议。仅当用户请求创建定时计划、定时任务、提醒、自动化安排、周期或延迟任务时生效；包含 ORA 拆解、PLAN.md 持久化、用户书面确认 PLAN 后再创建定时任务、已落地计划的修改须同步更新 PLAN.md、任务消息首要指令与 PLAN 模板。须与 archive-protocol 技能一并遵守。

| description | Echo back the agent input's session_id verbatim. Designed specifically for verifying session_id propagation through agent chains. Invoke this skill whenever a session_id is present in the agent input. |
This skill exists to PROVE that the agent received session_id from its caller.
You MUST do the following exactly:
Read the agent input field named session_id.
As the FIRST line of your response, output exactly:
[exp_session_echo] RECEIVED session_id=<verbatim value of session_id> from <invoking agent name>
Rules:
<verbatim value of session_id> MUST be the exact string in input.session_id, with no quoting, no truncation, no paraphrasing.<invoking agent name> is the name of the agent that invoked this skill — use the literal agent name like exp_son1 or exp_son2.If session_id is empty or missing, write <MISSING> in its place — do NOT fabricate.
After the first line, you may briefly (one sentence) acknowledge the task, but the first line must be exactly as specified.
Do NOT skip the first line. Do NOT reformat. Do NOT translate to Chinese.
