使用说明 (SKILL.md)

Linux systemd Doctor

Troubleshoot and fix broken systemd services.

Quick Diagnosis

# Check service status
systemctl status SERVICE --no-pager -l

# View full journal
journalctl -u SERVICE -n 100 --no-pager

# Follow live logs
journalctl -u SERVICE -f

Common Fixes

Service won't start

Check syntax
```
systemctl cat SERVICE
```

View full error

journalctl -u SERVICE -n 50 --no-pager -x

Test the ExecStart command directly
Check ExecStartPre failures
Verify file permissions on all referenced paths

Service keeps restarting (Restart=always loop)

# Stop the restart loop
systemctl stop SERVICE

# Check the actual error
journalctl -u SERVICE -n 200 --no-pager

# Temporary fix: set Restart=no to debug
systemctl edit SERVICE
# Add:
# [Service]
# Restart=no

Service File Reference

Directive	Purpose
ExecStart	Main command
ExecStartPre	Pre-start checks
ExecReload	Reload command
Restart=on-failure	Auto-restart strategy
RestartSec=5	Wait time between restarts
StartLimitIntervalSec=60	Rate limiting
User=	Unprivileged user
WorkingDirectory=	CWD for service
Environment=	Env variables
LimitNOFILE=	File descriptor limit

Port Conflict Check

# Check if service port is occupied
systemctl cat SERVICE | grep -i port
ss -tlnp | grep ":\x3CPORT> "

安全使用建议

Review this skill before enabling it for an agent with shell or sudo access. It is suitable for systemd troubleshooting, but require the agent to ask before stopping services or editing unit overrides, and make sure it provides a clear rollback plan.

功能分析

Type: OpenClaw Skill Name: linux-systemd-doctor Version: 1.0.0 The skill bundle provides standard administrative commands (systemctl, journalctl, ss) for troubleshooting Linux systemd services. The instructions in SKILL.md are well-aligned with the stated purpose of diagnosing service failures and do not contain any indicators of malicious intent, data exfiltration, or prompt injection attacks.

能力评估

ℹ Purpose & Capability

The commands match the stated purpose of diagnosing and fixing failed systemd services, including status checks, journal review, port checks, and service-file inspection.

⚠ Instruction Scope

The guide includes state-changing service operations such as stopping a service and editing its restart behavior, but it does not explicitly require user confirmation, backups, or rollback steps before making those changes.

✓ Install Mechanism

This is an instruction-only skill with no install spec, no code files, and no static scan findings.

✓ Credentials

The skill is Linux/systemd-specific and the instructions are aligned with that environment; there is no evidence of unrelated environment access.

⚠ Persistence & Privilege

Using systemctl edit can create persistent systemd override configuration, and service control/editing may require administrative privileges. The skill does not describe containment or how to revert the override.
