From f4179fbfb9624d0134a92e1481e2746a933a1462 Mon Sep 17 00:00:00 2001 From: EMRG Evolution Date: Wed, 21 Oct 2026 16:08:18 +0800 Subject: [PATCH 1/3] emrg: a feishu task type, with every message to a third party gated by its own approval Adds the task type `feishu`: a template that reads the host's Feishu messages, judges each one, does what needs no permission and asks where it does. A message to the host's own account needs no gate; a message to anybody else goes through `scripts/feishu-gate.py`, which holds the exact text, records the host's approval and refuses a second send on one approval. The gate is where the rule lives: the template describes how to use it, so the boundary is a mechanism rather than a prompt sentence. --- Agent.md | 8 +- emrg/server/feishu_prompt.md | 71 +++++ emrg/server/scheduler.py | 1 + scripts/check-rant-citations.py | 1 + scripts/feishu-gate.py | 447 ++++++++++++++++++++++++++++++++ tests/test_feishu_gate.py | 353 +++++++++++++++++++++++++ tests/test_prompt_templates.py | 1 + tests/test_scheduler.py | 39 +++ 8 files changed, 917 insertions(+), 4 deletions(-) create mode 100644 emrg/server/feishu_prompt.md create mode 100755 scripts/feishu-gate.py create mode 100644 tests/test_feishu_gate.py diff --git a/Agent.md b/Agent.md index 4569459c..dcba26f5 100644 --- a/Agent.md +++ b/Agent.md @@ -1,6 +1,6 @@ # EMRG — Agent.md -> **Principles and conventions only** — what to obey, and how to decide.
