nano_agent_evo — Evolution Session Report

English | 中文版

Background

This repository was automatically created by evolve_session.sh from the nano_agent_team_selfevolve project — a multi-agent framework that features an unattended self-evolution workflow.

The self-evolution system works as follows:

1. An Evolution Architect agent analyzes the framework and proposes improvements
2. It spawns Researcher, Auditor, and Historian agents for multi-angle research
3. Developer agents implement changes, Tester agents verify, Reviewer agents review
4. Each round runs in an isolated git worktree; successful rounds accumulate into a chain of branches

This session repo captures the full output of one evolution run, including all branches, reports, and the final manually-debugged result.

Session Configuration

Setting	Value
Date	2026-03-06 22:58 ~ 2026-03-07 01:05
Model	deepseek/deepseek-reasoner
Rounds	3 (max)
Base branch	main (from upstream)
Script	evolve_session.sh 3 deepseek/deepseek-reasoner --approve

Evolution Results

Round 1 — FAIL

• Proposal: Add /export slash command for TUI conversation export
• Direction: FEATURE — new tool + TUI command
• Failure reason: The Developer agent accidentally modified evolve.sh, a protected file. The quality gate caught this and the round was rolled back.
• Research findings: Auditor identified conversation export as the top user-facing gap; Researcher found observability/debugging as a hot topic.

Round 2 — FAIL

• Failure reason: DeepSeek API returned 402 Insufficient Balance — the account ran out of credits.

Round 3 — FAIL

• Failure reason: Same as Round 2 — insufficient API balance.

Score: 0 PASS / 3 FAIL

Manual Debug & Feature Implementation

Since all 3 rounds failed (Round 1 had the right idea but violated a constraint, Rounds 2-3 had no API budget), the feature from Round 1 was manually implemented and debugged on the main branch.

New Feature: /export Conversation Export

What it does: Users can export their TUI conversation history to Markdown, JSON, or plain text files.

Usage (TUI slash command):

/export                      # Export as markdown to ~/conversation_<timestamp>.md
/export json                 # Export as JSON
/export text /tmp/chat.txt   # Export as plain text to specific path

Usage (Agent tool): Agents can also call export_conversation as a tool to save conversations programmatically.

Files Changed

File	Change
backend/tools/export_conversation.py	NEW — ExportConversationTool (supports md/json/txt)
src/tui/slash_commands.py	Added /export command + updated /help
main.py	Wired ExportConversationTool into CLI entry point
src/tui/agent_bridge.py	Wired ExportConversationTool into TUI entry point (both chat and swarm modes)

Issues Found & Fixed

1. Protected file violation (Round 1): The evolution agent modified evolve.sh which is on the protected list. This was the root cause of Round 1 failure. The manual implementation avoids this entirely.
2. API budget exhaustion (Rounds 2-3): DeepSeek account balance was insufficient. Not a code issue — operational constraint.
3. Branch name conflict (origin vs git remote origin): evolve_session.sh created a branch named origin which conflicted with the git remote of the same name, causing warning: refname 'origin' is ambiguous. Fixed upstream by renaming the branch to baseline.

Verification

All tests passed:

• ExportConversationTool: markdown, JSON, plain text export all produce correct output
• Empty conversation edge case returns appropriate message
• Tool schema generates valid OpenAI function calling format
• Import chain works for both entry points (main.py and agent_bridge.py)

nano_agent_evo — 演化会话报告

English | 中文版

项目背景

本仓库由 nano_agent_team_selfevolve 项目的 evolve_session.sh 脚本自动创建——这是一个多 Agent 协作框架，核心特色是无人值守的自进化工作流。

自进化系统的运作方式：

1. Evolution Architect Agent 分析框架现状并提出改进方案
2. 生成 Researcher、Auditor、Historian Agent 进行多角度调研
3. Developer Agent 实现代码、Tester Agent 验证、Reviewer Agent 审查
4. 每轮在隔离的 git worktree 中工作；通过的轮次累积形成分支链

本会话仓库记录了一次完整的演化运行输出，包括所有分支、报告以及最终人工 debug 的结果。

本次运行配置

配置项	值
日期	2026-03-06 22:58 ~ 2026-03-07 01:05
模型	deepseek/deepseek-reasoner
轮数	3（最大值）
基础分支	main（来自上游）
执行脚本	evolve_session.sh 3 deepseek/deepseek-reasoner --approve

演化结果

第 1 轮 — FAIL

• 提案：为 TUI 添加 /export 斜杠命令，支持对话导出
• 方向：FEATURE — 新工具 + TUI 命令
• 失败原因：Developer Agent 意外修改了受保护文件 evolve.sh，质量门控检测到后回滚了该轮次
• 调研发现：Auditor 认为对话导出是最大的用户功能缺口；Researcher 发现可观测性/调试是热门方向

第 2 轮 — FAIL

• 失败原因：DeepSeek API 返回 402 Insufficient Balance——账户余额不足

第 3 轮 — FAIL

• 失败原因：同第 2 轮——API 余额不足

得分：0 PASS / 3 FAIL

人工 Debug 与功能实现

由于 3 轮全部失败（第 1 轮方向正确但违反了约束，第 2-3 轮无 API 预算），第 1 轮提出的功能被手动实现并在 main 分支上完成 debug。

新功能：/export 对话导出

功能说明：用户可以将 TUI 对话历史导出为 Markdown、JSON 或纯文本文件。

用法（TUI 斜杠命令）：

/export                      # 导出为 markdown 到 ~/conversation_<timestamp>.md
/export json                 # 导出为 JSON
/export text /tmp/chat.txt   # 导出为纯文本到指定路径

用法（Agent 工具）：Agent 也可以调用 export_conversation 工具以编程方式保存对话。

修改的文件

文件	变更
backend/tools/export_conversation.py	新建 — ExportConversationTool（支持 md/json/txt）
src/tui/slash_commands.py	添加 /export 命令 + 更新 /help
main.py	将 ExportConversationTool 集成到 CLI 入口
src/tui/agent_bridge.py	将 ExportConversationTool 集成到 TUI 入口（chat 和 swarm 模式）

发现并修复的问题

1. 受保护文件违规（第 1 轮）：演化 Agent 修改了受保护列表中的 evolve.sh，导致第 1 轮失败。手动实现完全避免了此问题。
2. API 预算耗尽（第 2-3 轮）：DeepSeek 账户余额不足。非代码问题——运营层面的限制。
3. 分支名冲突（origin vs git remote origin）：evolve_session.sh 创建了名为 origin 的分支，与同名 git remote 冲突，导致 warning: refname 'origin' is ambiguous。已在上游修复，将分支重命名为 baseline。

验证结果

所有测试通过：

• ExportConversationTool：markdown、JSON、纯文本导出均产出正确结果
• 空对话边界情况返回适当消息
• 工具 schema 生成有效的 OpenAI 函数调用格式
• 两个入口点（main.py 和 agent_bridge.py）的导入链均正常工作
