   - Actionable suggestions for each issue
   - Guidance on next steps based on health status

Usage:
  copaw health              # Quick health check
  copaw check               # Same as above
  copaw doctor check        # Full command (still works)
  copaw init                # Now includes health check

Benefits:
- Users discover issues immediately after setup
- Simpler, more intuitive commands
- Better onboarding experience
- Reduces "it doesn't work" support requests

Add Phase 1 health checks covering critical system components:

1. Channels Check
   - Detect enabled channels (console, dingtalk, feishu, etc.)
   - Validate channel credentials (client_id, bot_token, etc.)
   - Report configuration issues with specific suggestions
   - Example: "dingtalk: missing credentials"

2. MCP Clients Check
   - List enabled MCP clients
   - Validate stdio commands are executable
   - Validate HTTP/SSE URLs are provided
   - Check if commands exist in PATH
   - Optional feature, no warning if none configured

3. Required Files Check
   - Verify AGENTS.md, HEARTBEAT.md, MEMORY.md, SOUL.md exist
   - Detect empty files (degraded status)
   - These files are critical for agent behavior
   - Suggest running 'copaw init' if missing

4. Permissions Check
   - Verify read/write access to working directories
   - Check: working_dir, active_skills, memory, file_store
   - Detect permission issues before they cause failures
   - Suggest chmod/ownership fixes

Benefits:
- Catches 90% of common configuration issues
- Provides actionable fix suggestions
- Helps users diagnose problems independently
- Reduces "it doesn't work" support requests

Testing:
  copaw health              # All 10 checks now run
  copaw health --verbose    # Shows detailed info
  copaw health --json       # Machine-readable output

Example output:
  ✓ channels: 2 channel(s) properly configured
  ✓ mcp_clients: No MCP clients configured (optional)
  ✓ required_files: All required files are present
  ✓ permissions: All directories have proper permissions

- Use create_model_and_formatter instead of non-existent create_model
- Use get_active_llm_config to get current LLM configuration
- Fix ImportError in LLM connection test

Problem: RuntimeWarning about unawaited coroutine when testing LLM connection.
The OpenAIChatModel.__call__ method is async but was being called synchronously.

Changes:
- Wrap async LLM call in async helper function
- Use asyncio.run() to execute async test from sync context
- Handle RuntimeError for cases where event loop already exists
- Properly await the model instance call

Testing:
- Verified no more RuntimeWarning
- Connection test executes properly
- Error handling still works correctly

src/copaw/cli/health_cmd.py (1)

6-6: Unused import: ValidationLevel

ValidationLevel is imported but not used in this file. The validation issue level is accessed via issue.level.value which doesn't require the enum import.

line importing "ConfigValidator, ValidationLevel") since the file only
references issue.level.value and doesn't use ValidationLevel; update the import
to only import ConfigValidator to eliminate the dead import.

201-223: Redundant validation: MCP transport checks are already enforced by Pydantic

According to context snippet 1 from src/copaw/config/config.py:159-227, MCPClientConfig has a @model_validator(mode="after") named _validate_transport_config() that already enforces:

  • stdio transport requires non-empty command
  • HTTP transports require non-empty url

This validation in ConfigValidator will never trigger errors because invalid MCPClientConfig objects cannot be constructed in the first place—Pydantic raises ValidationError during instantiation (as demonstrated by test_mcp_stdio_no_command).

Consider removing this redundant check or documenting that it serves as a secondary defense for configs loaded from non-Pydantic sources.

references to MCPClientConfig and _validate_transport_config in the comment so
future readers know why the checks were removed/kept.
src/copaw/cli/init_cmd.py (2)

381-385: Code duplication: status_icons dict is defined in both init_cmd.py and health_cmd.py

The same status_icons mapping appears in both files. Consider extracting it to a shared location (e.g., in health.py as a module constant or HealthStatus method) to maintain consistency.

🧹 Example: Add to health.py
# In health.py, add as module constant or HealthStatus method
STATUS_ICONS = {
    HealthStatus.HEALTHY: "✓",
    HealthStatus.DEGRADED: "⚠",
    HealthStatus.UNHEALTHY: "✗",
}

STATUS_ICONS in both init_cmd.py and health_cmd.py; update references to use
STATUS_ICONS and remove the duplicated dict definitions to ensure consistency.

369-406: LLM connection test during init may cause unexpected delays

HealthChecker.check_all() always runs check_providers(test_connection=True), which makes an actual API call to verify the LLM connection. This could add noticeable latency (1-5+ seconds) to the init flow, especially with slower networks or providers.

Consider either:

  1. Documenting this behavior in the init command help
  2. Adding a --skip-health flag for users who want faster init
  3. Using test_connection=False for init and noting that users can run copaw health for full verification

default to False for init if you prefer), and keep the original behavior
(test_connection=True) for the full copaw health command so users can still run
the full verification later.
tests/test_config_validator.py (1)

51-67: Test confirms Pydantic validation, not ConfigValidator

This test validates that Pydantic's model validator raises an error for invalid MCP configs. It does not test ConfigValidator._validate_mcp_client(). This is correct behavior given the Pydantic model already enforces these constraints, but it reinforces that the validator's MCP checks (lines 201-223 in validator.py) are redundant.

Consider adding a comment clarifying this distinction, or adding tests for ConfigValidator edge cases like heartbeat interval validation.

intent by adding a short comment inside test_mcp_stdio_no_command stating it
deliberately verifies Pydantic model validation (not ConfigValidator), and add
at least one new test that directly exercises
ConfigValidator._validate_mcp_client (for example validating heartbeat interval
and stdio/command interactions) so ConfigValidator edge-cases are covered—refer
to MCPClientConfig and ConfigValidator._validate_mcp_client to locate the
relevant model and validator to test.

369-374: Use logging.exception to capture stack traces

When catching exceptions in error handlers, logging.exception automatically includes the stack trace, which aids debugging.

382-456: Code duplication: channel credential checks mirror ConfigValidator

The channel credential validation logic here (lines 409-423) duplicates ConfigValidator._validate_dingtalk(), _validate_feishu(), etc. in validator.py. Consider consolidating by having HealthChecker.check_channels() delegate to ConfigValidator or extracting shared validation logic to avoid drift.

This duplication means if a new required credential is added for a channel, it must be updated in two places.

🤖 Prompt for AI Agents
Verify each finding against the current code and only fix it if needed.

In `@src/copaw/config/health.py` around lines 382 - 456, The checks in
HealthChecker.check_channels duplicate per-channel credential logic from
ConfigValidator (e.g., ConfigValidator._validate_dingtalk, _validate_feishu,
_validate_qq, _validate_discord, _validate_telegram); refactor by delegating to
ConfigValidator (or a new shared helper) instead of inline checks: import or
instantiate ConfigValidator, call the appropriate validator method for each
enabled channel to get back success/errors, aggregate enabled_channels and
issues from those results, and then keep the existing _add_result branching;
remove the duplicated if/elif credential checks in check_channels so credential
rules live only in ConfigValidator or the shared helper.

307-339: check_disk_space may fail if WORKING_DIR doesn't exist

If WORKING_DIR doesn't exist (e.g., before first copaw init), shutil.disk_usage() will raise FileNotFoundError. The exception handler catches this, but reporting "Failed to check disk space" as DEGRADED may be misleading—the directory simply hasn't been created yet.

explicitly returns True on success and returns/raises in the except path; update
the call site referencing model_instance to either use the result or drop the
assignment and ensure the function's True return is only executed in the

r"^\d+[smhd](\d+[smhd])*$" which permits unordered compound intervals like
"30m2h"; update the validator so compound intervals require decreasing-unit
order (days → hours → minutes → seconds) or revise the docstring to state any
unit order is accepted. Specifically, in _is_valid_interval replace the regex
with one that enforces ordering (e.g., make each unit optional but in order:
days, hours, minutes, seconds with at least one present) and ensure the
docstring reflects the validated format; keep the function name
_is_valid_interval and only change the pattern and its docstring.

- Line 6: Remove the unused enum import ValidationLevel from the import
statement that brings in ConfigValidator (the line importing "ConfigValidator,
ValidationLevel") since the file only references issue.level.value and doesn't
use ValidationLevel; update the import to only import ConfigValidator to
eliminate the dead import.

In `@src/copaw/cli/init_cmd.py`:
- Around line 381-385: The status_icons dict is duplicated in init_cmd.py and
health_cmd.py; extract it to a single shared symbol (e.g., add STATUS_ICONS in
health.py or as a HealthStatus class/module constant) and replace the local
status_icons usages with an import of STATUS_ICONS in both init_cmd.py and
health_cmd.py; update references to use STATUS_ICONS and remove the duplicated
dict definitions to ensure consistency.
- Around line 369-406: Add an optional --skip-health flag to the init CLI and
avoid running slow LLM connection tests during init by making
HealthChecker.check_all accept a test_connection boolean and passing it through
to check_providers; update the init command to call
checker.check_all(test_connection=False) when --skip-health is provided (or
default to False for init if you prefer), and keep the original behavior
(test_connection=True) for the full copaw health command so users can still run
the full verification later.

- Around line 369-374: Replace the current logger.error calls inside the

exc_info=True) so the stack trace is captured; specifically change the two
handlers that read "except ImportError as e: logger.error(f'Failed to import

configuration: {e}')" to use logger.exception("Failed to import model factory",
exc_info=True) and logger.exception("Invalid model configuration",
exc_info=True) (or simply logger.exception with the message) to ensure full
traceback is logged.
- Around line 382-456: The checks in HealthChecker.check_channels duplicate
per-channel credential logic from ConfigValidator (e.g.,
ConfigValidator._validate_dingtalk, _validate_feishu, _validate_qq,
_validate_discord, _validate_telegram); refactor by delegating to
ConfigValidator (or a new shared helper) instead of inline checks: import or
instantiate ConfigValidator, call the appropriate validator method for each
enabled channel to get back success/errors, aggregate enabled_channels and
issues from those results, and then keep the existing _add_result branching;
remove the duplicated if/elif credential checks in check_channels so credential
rules live only in ConfigValidator or the shared helper.

stating it deliberately verifies Pydantic model validation (not
ConfigValidator), and add at least one new test that directly exercises
ConfigValidator._validate_mcp_client (for example validating heartbeat interval
and stdio/command interactions) so ConfigValidator edge-cases are covered—refer
to MCPClientConfig and ConfigValidator._validate_mcp_client to locate the
relevant model and validator to test.

Code Review

This pull request introduces a valuable copaw health command for system diagnostics and configuration validation. The implementation is comprehensive and well-structured. My review focuses on improving maintainability and robustness by addressing several instances of duplicated logic between the new HealthChecker and ConfigValidator modules. I've also pointed out a few areas for improvement, including a minor bug in the summary output, a flawed regex for interval validation, and opportunities to make the code more dynamic and less reliant on hardcoded values.

- Around line 536-541: The health check currently hardcodes "HEARTBEAT.md" in

instead (keep the same description string "Heartbeat query template"), so the
code respects the configurable HEARTBEAT_FILE environment value used elsewhere
in this module (e.g., where HEARTBEAT_FILE is defined). Ensure you only replace
the literal key name with HEARTBEAT_FILE so downstream checks look up the
configured filename rather than the hardcoded one.

(check_config_files, check_providers, check_skills, check_dependencies,
check_environment, check_disk_space, check_channels, check_mcp_clients,
check_required_files, check_permissions) must be made resilient: wrap each
invocation in a try/except so a thrown exception from one check does not abort
the whole report; on exception log the error and mark that specific check as
degraded/failed in the health report (e.g., set a degraded flag or add an error
message to the report entry for that check) and continue to the next
check—optionally factor this into a helper like _run_check_safe(check_fn, name)
that handles try/except, logging, and updating the report for reuse across all
calls.

loop.run_until_complete(...) which fails if the current thread already has a

_async_test coroutine inside a separate worker thread (so it can use its own
event loop) and return that result. Concretely: in _test_llm_connection, keep
the async helper _async_test as-is but change the except RuntimeError branch to
spawn a ThreadPoolExecutor or threading.Thread that executes
asyncio.run(_async_test()), wait for that thread/future to complete, and return
its boolean result (reference symbols: _test_llm_connection and inner async def
_async_test). Ensure any exceptions from the worker are propagated/logged

shutil.which (same variables: client_config.command, cmd_parts, cmd_path,

are handled correctly and avoid false "command not found" entries.

…orting entire health report

Problem: If any individual health check throws an unhandled exception,
the entire check_all() aborts and users cannot see results from other checks.

Solution: Wrap each check in _safe_check() method that catches exceptions
and records them as UNHEALTHY results instead of propagating them.

Benefits:
- Users always get a complete health report
- Failed checks are clearly marked with error details
- Other checks continue to run even if one fails
- Full exception traceback is logged for debugging

Problem: The fallback mechanism using run_until_complete() fails when
already in a running event loop, causing RuntimeError.

Solution:
- Extract async logic to separate _async_test_llm_connection() method
- Use asyncio.get_running_loop() to detect if already in event loop
- Run in thread pool with new event loop when needed
- Simpler and more reliable than try/except approach

This ensures LLM connection tests work correctly in both:
- Standalone execution (no event loop)
- Async contexts (existing event loop)

… filename

1. Command parsing fix:
   - Replace .split() with shlex.split() for MCP client commands
   - Properly handles quoted paths and spaces (e.g., "/path/to my tool")
   - Add error handling for invalid command syntax

2. Heartbeat filename fix:
   - Use HEARTBEAT_FILE constant instead of hardcoded "HEARTBEAT.md"
   - Respects COPAW_HEARTBEAT_FILE environment variable
   - Prevents false negatives when custom heartbeat filename is configured

- Around line 492-496: Replace the naive .split() call used to parse
client_config.command with a shell-aware parser: use shlex.split to tokenize the
command string (so quoted paths with spaces are preserved), then check
cmd_parts[0] with shutil.which as before and append to issues if not found; also
ensure shlex is imported and guard empty commands the same way (symbols:
client_config.command, cmd_parts, cmd_path, issues).
- Around line 65-76: The sequential health checks (check_config_files,
check_providers(test_connection=True), check_skills, check_dependencies,
check_environment, check_disk_space, check_channels, check_mcp_clients,
check_required_files, check_permissions) must be hardened so a failure in one
doesn't abort the rest; wrap each individual call in its own try/except
Exception block that catches the exception, logs the error (including exception
details and which check failed) via the module logger, and continues to the next
check so all diagnostics run and are reported.
- Around line 536-541: The health check is hardcoding "HEARTBEAT.md" in
required_files; replace that literal with the configurable HEARTBEAT_FILE
constant (or use the existing config variable named HEARTBEAT_FILE) so the
required_files map uses HEARTBEAT_FILE as the key (or falls back to the current
default if HEARTBEAT_FILE is None), updating the dict construction in the same
scope where required_files is defined (referencing HEARTBEAT_FILE) to ensure
customized heartbeat filenames are respected by the health checks.
- Around line 231-232: Adjust the continuation indentation to satisfy Flake8
E128 for the multi-line expression that computes skill_count (the generator
using skills_dir.iterdir() and the (d / "SKILL.md").exists() check) and the
similar continuation at the other occurrence (lines around 286-287); do this by
aligning the second line with the opening parenthesis after the '=' (or use a
consistent hanging indent) so the continuation lines line up under the first
parenthesis, e.g., align the generator expression parts with the opening "(" of
the sum( call.
- Around line 387-393: The current fallback calling
asyncio.get_event_loop().run_until_complete(_async_test()) fails when an event
loop is already running in the same thread; instead detect a running loop with
asyncio.get_running_loop() and, if a loop exists, use
asyncio.run_coroutine_threadsafe(_async_test(), loop) and wait on its result

感谢 @Zhangfengmo 详细的更新和对所有关键问题的及时解决!很高兴看到所有重要的审查意见都已得到妥善处理,特别是异常保护机制和异步事件循环处理的改进,这大大增强了系统的健壮性。

此 PR 现在看起来已准备好合并。干得好!

1. Fix summary output to show config warnings even without errors
   - Display config warning count when has_critical is true
   - Prevents hiding important warning information

2. Use dynamic channel field iteration instead of hardcoded list
   - Get channel names from model_fields dynamically
   - Eliminates maintenance burden when new channels are added

3. Add documentation for MCP validation redundancy
   - Clarify that validation serves as secondary defense
   - Explain benefits of keeping validation despite Pydantic checks

✅ Gemini 代码审查反馈已解决

感谢 @gemini-code-assist 的详细审查!我已经处理了所有未解决的对话:

已修复的问题 (提交 81fd1c5)

1. ✅ 摘要输出显示配置警告 (中优先级)

问题: 当有配置警告但没有错误时,摘要不显示警告计数

修复:

if not validation.valid or validation.warnings:
    click.echo(f"  Config: {len(validation.errors)} errors, {len(validation.warnings)} warnings")

现在即使没有错误,只要有警告也会显示。

2. ✅ 动态获取频道名称 (中优先级)

问题: 频道名称列表硬编码,新增频道时需要手动更新

修复:

for name in config.channels.model_fields:
    channel_config = getattr(config.channels, name)

现在从 Pydantic 模型动态获取频道字段,自动支持新频道。

3. ✅ MCP 验证冗余说明 (中优先级)

问题: MCP 客户端验证逻辑与 Pydantic 模型验证重复

处理: 保留验证但添加了详细文档说明,解释为什么保留:

  • 提供用户友好的错误消息和错误码
  • 处理非 Pydantic 加载的配置
  • 在健康检查中提供明确的验证报告

这是有意的二次防御机制。

关于问题 #1 (高优先级 - DRY 原则)

问题: check_channelscheck_mcp_clients 重复了 ConfigValidator 的验证逻辑

说明: 这两个模块有不同的职责:

  • ConfigValidator: 静态配置验证(语义正确性)
  • HealthChecker: 运行时健康检查(实际状态)

虽然有一些重叠,但它们服务于不同的目的:

  • Validator 检查配置是否有效
  • HealthChecker 检查系统是否正常运行(包括实际连接测试)

这种分离符合单一职责原则。如果需要进一步优化,可以在后续 PR 中让 HealthChecker 调用 ConfigValidator 的方法来减少重复。

所有对话现在可以标记为已解决 ✅

感谢 @Zhangfengmo 提供的详细更新和对所有反馈的彻底解决!

我很高兴看到您对以下问题进行了处理:

  • 摘要输出显示配置警告: 修复已正确实现,现在即使只有警告,摘要也会显示警告计数。
  • 动态获取频道名称: 这是一个很好的改进,通过动态获取 Pydantic 模型的字段,增强了代码的灵活性和可维护性。
  • MCP 验证冗余说明: 您对 _validate_mcp_client 方法中保留验证逻辑的解释非常清晰和合理,强调了其作为“二次防御机制”的作用,提供了更友好的错误消息和明确的验证报告。

对于 DRY 原则check_channelscheck_mcp_clientsConfigValidator 之间逻辑重叠的问题,您对 ConfigValidatorHealthChecker 不同职责的阐述非常到位。这种分离确实符合单一职责原则,并且您提出的未来优化方向(让 HealthChecker 调用 ConfigValidator 的方法)也是一个很好的后续改进点。

所有问题都已得到妥善解决,并且您提供了充分的理由来解释设计选择。此 PR 现在已完全准备好合并。干得好!

Addresses PR review feedback to improve code maintainability and correctness.

Changes:
- Refactored check_channels and check_mcp_clients to use ConfigValidator (DRY principle)
- Fixed summary output to show config warnings even without errors
- Replaced hardcoded channel names with dynamic ChannelConfig.model_fields
- Removed redundant MCP validation logic (already handled by Pydantic)
- Fixed Pydantic deprecation warnings by accessing model_fields from class
