From 7f8c3453e1488ddab22a4c470bd72c4faa7f49db Mon Sep 17 00:00:00 2001 From: chengyongru <2755839590@qq.com> Date: Sat, 11 Jul 2026 16:51:25 +0800 Subject: [PATCH] refactor(agent): gate sustained goals behind explicit /goal Replace the legacy long-goal skill contract with command-scoped goal tools and runtime guidance. Keep goal state durable across continuations while restricting create and replace mutations to explicit user /goal turns. --- AGENTS.md | 2 +- nanobot/agent/context.py | 66 ++- nanobot/agent/goal_permission.py | 29 ++ nanobot/agent/loop.py | 49 ++- nanobot/agent/tools/long_task.py | 350 +++++++++------ nanobot/command/builtin.py | 23 +- nanobot/command/router.py | 5 +- nanobot/providers/base.py | 3 +- nanobot/session/goal_state.py | 26 +- nanobot/session/turn_continuation.py | 15 +- nanobot/skills/README.md | 1 - nanobot/skills/long-goal/SKILL.md | 79 ---- nanobot/templates/agent/goal_runtime.md | 31 ++ nanobot/utils/runtime.py | 3 +- tests/agent/test_context_builder.py | 51 +++ tests/agent/test_loop_runner_integration.py | 143 ++++++ tests/agent/test_loop_save_turn.py | 80 +++- tests/agent/test_subagent_lifecycle.py | 6 +- tests/agent/tools/test_long_task.py | 463 +++++++++++++++----- tests/command/test_model_command.py | 41 +- tests/command/test_skill_command.py | 8 + tests/session/test_goal_state.py | 18 + tests/session/test_turn_continuation.py | 10 +- tests/tools/test_filesystem_tools.py | 4 +- 24 files changed, 1131 insertions(+), 375 deletions(-) create mode 100644 nanobot/agent/goal_permission.py delete mode 100644 nanobot/skills/long-goal/SKILL.md create mode 100644 nanobot/templates/agent/goal_runtime.md diff --git a/AGENTS.md b/AGENTS.md index 8cb9be98..1b531835 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -46,7 +46,7 @@ Messages flow through an async `MessageBus` (`nanobot/bus/queue.py`) that decoup - **Command Router** (`nanobot/command/`): Slash command routing and built-in command handlers. - **Heartbeat** (`nanobot/templates/HEARTBEAT.md`): Periodic task list checked via `cron` jobs (legacy dedicated service removed). - **Pairing** (`nanobot/pairing/`): DM sender approval store with persistent pairing codes per channel. -- **Skills** (`nanobot/skills/`): Built-in skill definitions (long-goal, cron, github, image-generation, etc.) loaded into agent context. +- **Skills** (`nanobot/skills/`): Built-in skill definitions (cron, github, image-generation, etc.) loaded into agent context. - **Security** (`nanobot/security/`): PTH file guard and other security measures activated at CLI entry. ### Entry Points diff --git a/nanobot/agent/context.py b/nanobot/agent/context.py index 59210d7b..ee87e4d8 100644 --- a/nanobot/agent/context.py +++ b/nanobot/agent/context.py @@ -12,7 +12,7 @@ from nanobot.agent.tools import mcp as mcp_tools from nanobot.agent.tools.registry import ToolRegistry from nanobot.apps.cli import utils as cli_app_utils from nanobot.bus.events import InboundMessage -from nanobot.session.goal_state import goal_state_runtime_lines +from nanobot.session.goal_state import goal_state_runtime_lines, sustained_goal_active from nanobot.utils.helpers import ( current_time_str, detect_image_mime, @@ -56,7 +56,11 @@ class ContextBuilder: """Builds the context (system prompt + messages) for the agent."""
