Description
快速识别并立即中断当前执行任务，清理所有相关资源，节省 token 和时间，准备执行新任务。
Usage Guidance
This skill is coherent with its stated purpose, but it needs broad runtime privileges (process/subagent termination and filesystem writes). Before installing: 1) Confirm what the platform-provided 'subagents' and 'process' tools can access — are they limited to the agent's own children or can they affect system/global processes? 2) Ensure kills are scoped to resources owned by the current task/session and that confirmation behavior (confirm vs. immediate kill) matches your safety needs. 3) Consider enabling a confirmation prompt and restricting tempDir to a dedicated sandbox. 4) Test in a safe/sandbox environment to observe which processes/files it actually terminates. If you cannot verify tool scoping, avoid granting this skill process-level permissions.
Capability Analysis
Type: OpenClaw Skill
Name: task-killer
Version: 1.0.0
The 'task-killer' skill is a legitimate utility designed to interrupt ongoing agent tasks, terminate subagents, and kill background processes to save tokens and time. The implementation in index.js and the instructions in SKILL.md are transparent and align perfectly with the stated purpose, using the subagents, process, and filesystem tools for resource management and logging without any evidence of malicious intent, data exfiltration, or unauthorized access.
Capability Assessment
Purpose & Capability
Name/description align with requested capabilities: the skill declares and uses tools for subagents, process management, and filesystem cleanup — these are expected for a task-killer.
Instruction Scope
SKILL.md and index.js instruct the agent to list and kill subagents and processes and to delete temp files, but they do not require or enforce scoping to only those resources owned by the current task/session. This could allow killing unrelated agents/processes or removing files outside a safe workspace. There are also minor contradictions about immediate no-tool-calls vs. performing cleanup actions.
Install Mechanism
No install spec and no external downloads; the skill is instruction-first with a small JS implementation included, so it does not pull arbitrary code from remote hosts.
Credentials
No environment variables or external credentials requested. However the skill requires access to high-privilege tools (subagents, process, filesystem) which is proportionate to its purpose but nevertheless powerful — ensure those tool APIs have appropriate scoping/permissions.
Persistence & Privilege
always:false and no indications the skill will force-enable itself or change other skills' configs. It writes a local interrupt record file by design; that is expected behavior.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install task-killer - After installation, invoke the skill by name or use
/task-killer - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.0.0
Initial release of the task-killer skill.
