- Harden _connect_mcp to require enabled=True and command to be a non-empty str - Ignore malformed args instead of passing them to MCPClient - Prevents MagicMock config from triggering Pydantic validation errors
- Remove trailing blank/whitespace lines after stripping config hunks - Ensure patch always ends with exactly one newline - Config patterns: pyproject.toml, setup.cfg, setup.py, tox.ini, Makefile, .github/, .circleci/, .travis.yml, conftest.py Co-Authored-By: Claude <noreply@anthropic.com>
Stripping config hunks from unified diffs breaks the context line count, leading to 'patch does not apply cleanly' errors. The pyproject.toml pollution does not affect SWE-bench evaluation (test env uses Docker images with its own build deps). Kept _strip_config_changes function for potential future use with a more robust implementation. Co-Authored-By: Claude <noreply@anthropic.com>
- coder.yaml: detailed 5-phase workflow, tool cheat sheet, explicit DON'Ts - str_replace_file.py: descriptive tool hint (recommended over execute_shell+sed) - execute_shell.py: explicit warning not to use for file reading/editing Co-Authored-By: Claude <noreply@anthropic.com>
Extracted from Claude Code's prompts.ts (914-line prompt engineering): - CRITICAL tool usage rules: dedicated tools over execute_shell, with table - Code modification principles: no extra features, no speculative abstractions, no error handling for impossible scenarios, don't edit unread code - Comment policy: default to no comments, explain WHY not WHAT - Error handling: diagnose before switching, don't blindly retry, no --force - Reporting: honest outcomes, verify before claiming complete - Task management: break down with set_todo, mark done immediately Co-Authored-By: Claude <noreply@anthropic.com>
Add DirectAgent that skips the supervisor/worker/IPC pipeline entirely. LLM calls tools directly in-process — same architecture as Claude Code. - agent/direct_agent.py: in-process LLM loop with direct tool calls - runner.py: _run_task_direct mode (no subprocess, no IPC serialization) - cli.py: --mode direct option Co-Authored-By: Claude <noreply@anthropic.com>
- build_tools_payload is in agent.llm.parser, not agent.tools - ToolContext takes 'workspace' kwarg, not 'workspace_path' Co-Authored-By: Claude <noreply@anthropic.com>
In direct mode, there is no user to confirm dangerous shell commands.
execute_shell calls (pytest, git diff, cd) were all being blocked by
the safety classifier ('requires user confirmation'). Use execute_forced
to auto-approve, matching supervisor's confirm_callback=lambda: True.
Also added detailed tool call logging for debugging.

v4-pro at temperature=0.7 tends to get distracted by test failures and wanders into environment debugging loops. Temperature=0 makes it more focused on the source code fix. Co-Authored-By: Claude <noreply@anthropic.com>
…use analysis Documents every experiment: git mirror, tool reduction, prompt alignment, supervisor removal, config stripping attempt, temperature tuning. Explains why v4-pro converges at 20% regardless of architecture: model attention drift in multi-turn conversations, triggered by test failure output in tool results.

- direct_agent: 编辑前强制重读文件（_ensure_file_read_before_edit），模仿 Claude Code file-state 跟踪，防止基于过期记忆编辑；上下文压缩 _compact_messages； trace 事件日志 _log_event - safety: python -m pytest/py_compile/compileall 归类 HARMLESS（SWE-bench 验证 命令需执行）；放宽 python -c harmless 判定 - coder 角色: 改用 str_replace_file 做最小改动，write_file 移入 forbidden - 测试同步: test_role_loader 断言 str_replace_file/write_file forbidden； test_e2e 用 python3 -m pytest（python 不在 PATH，且 sys.executable 路径含 /bin 触发 FORBIDDEN） 全部 321 测试通过 Co-Authored-By: Claude <noreply@anthropic.com>
合规修复：_build_goal_description 此前把 FAIL_TO_PASS 测试名喂给 agent， 相当于给出验收标准，违反 SWE-bench 盲改标准。改为只给 issue 描述，验收测试 由评估 harness 在 agent 不可见情况下运行。 - runner._build_goal_description: 移除 fail_test_list 泄露，验证步骤改为 对照 problem statement 推理 + 仓库已有测试自检，禁止猜测隐藏测试 - evaluator._run_pytest_cases: pytest 二进制不在 PATH 时回退 sys.executable -m pytest，避免 "pytest not found in PATH" - README: 标注旧 16/20 结果含泄露已失效待重跑，更新关键优化描述 Co-Authored-By: Claude <noreply@anthropic.com>
- scripts/compare_three_systems.py: direct/Claude Code/SWE-agent 三系统全量 对比，支持 --rerun-failed - swe_agent_local_runner.py + swe_agent_local_config/: SWE-agent v0.7.0 本地 persistent bash 环境配置与运行器 Co-Authored-By: Claude <noreply@anthropic.com>
- 明确历史数值已失效待合规重跑（含 fail_to_pass 泄露） - 澄清 SWE-agent 7/20 是更早旧值，最近一次运行 0/20 全 exit code 1 （numpy/pandas 版本冲突导致启动崩），已修复 - 评估器说明：direct/Claude 用 SWEBenchEvaluator，SWE-agent 用 DockerEvaluator Co-Authored-By: Claude <noreply@anthropic.com>
SWE-agent 0/20 全 exit code 1 根因：swe_agent_py311 环境的 numpy(1.24) 与 pandas(3.0) 冲突，import sweagent 直接崩。numpy 已升级到 >=1.26 修复， swe-agent 现可正常启动并跑 LLM（冒烟验证：进程持续 20min+ 有 deepseek API TCP 活动）。 - SWE_BENCH_DOCKER_SETUP.md 新增第 5 节：swe_agent_py311 环境搭建步骤、 numpy 依赖修复、API key 注入说明 Co-Authored-By: Claude <noreply@anthropic.com>
冒烟验证：swe-agent 环境修复后能启动并产出正确 patch（pytest-5103）， 但交互式 bash 模式极慢（275+ API 调用/任务），1200s 超时内常未跑完验证 就被 kill，patch 未收集判为未解决。完整 20 任务需调大 timeout（6h+）。 Co-Authored-By: Claude <noreply@anthropic.com>
When the agent tries to submit, run its pass_to_pass tests (test names from the SWE-bench spec — officially allowed, no test patch content used). If any previously-passing test now fails, reject the submission and feed the failed test names back to the agent so it can fix the regression, up to 2 attempts. This mirrors what a human engineer does before committing: run the test suite, and if something broke, fix it instead of committing a broken change. Motivated by pytest-11148 failing with only 1 pass_to_pass regression (130 passed, 1 failed) — the agent had the right fix but introduced a regression by also editing test_pathlib.py.
…back Three infrastructure fixes that caused 9/24 empty patches in the last batch: 1. DockerShell now holds client+container_id (not just container) and retries exec_run 3 times on connection errors, refreshing the container handle. Colima's socket drops intermittently during long runs, killing 3/24 cases with 'Connection aborted'. 2. Base-commit checkout now does 'git fetch --depth 1 origin <sha>' first, so a shallow-cloned cache can still check out old commits. This fixes the 2/24 sphinx cases that failed with 'git checkout -f <commit>'. 3. When both the official image pull and local env-image build fail (e.g. scikit-learn C-extension compile timeout), fall back to a bare python:3.10-slim image with the workspace mounted + git installed. The agent can still read/edit source and produce a patch, even without the project's compiled deps. Better than failing with an empty patch.
Address the docker instability that caused 6/24 RemoteDisconnected errors and 3/24 ImageNotFound errors in the v3 batch: 1. DockerShell._reconnect(): on connection error, fully rebuild the docker client (docker.from_env()) and re-fetch the container, not just clear the cached container object. A stale TCP connection to Colima's daemon can't be fixed without a new client. 2. Container create/start now retries 3 times with fresh clients, so a transient daemon drop at task start doesn't fail the whole task. 3. Per-task fresh docker client: each task creates a new client instead of reusing one across the entire batch (4-hour runs accumulate stale state). 4. evaluate_in_container(): docker-bash mode now evaluates in the *same* container the agent already ran in, instead of creating a second container. This eliminates an entire container lifecycle (create/start/ stop/remove) and its associated connection-error surface. 5. _ensure_bare_image(): pre-pull python:3.10-slim with retry, so the bare image fallback doesn't fail with ImageNotFound when Colima hasn't cached it.
Colima accumulates connection leaks over 2-3 hour batch runs, causing RemoteDisconnected errors. Now run_dataset restarts Colima every 6 tasks (configurable via docker_restart_interval), clearing stale connections before they manifest as failures. The restart is safe: it stops/starts Colima, waits for the daemon to come back, and verifies with a ping. If Colima isn't the runtime (e.g. Docker Desktop), it's a no-op.
…r is down get_diff() was not checking return codes, so when the container was stopped (e.g. after Colima restart), the error output from git status/diff was treated as patch content. This produced fake 'patches' containing docker error messages instead of code changes, which 6/24 cases suffered from. Now get_diff returns empty string if git status or git diff fails, so the case is correctly reported as 'empty patch' instead of 'patch with garbage'.
