# 内存快照
node skills/heap-dump/scripts/heap-dump.js snapshot
# 性能分析
node skills/heap-dump/scripts/profiler.js start "任务名" # 开始
node skills/heap-dump/scripts/profiler.js checkpoint "阶段" # 标记点

📊 触发方式
- 手动触发（按需使用的诊断工具，无需自动化）
⚠️ 注意事项
- heap snapshot 文件较大，建议分析后删除
- profiler 输出写入
memory/perf/目录 - 已合并 headless-profiler 功能
Usage Guidance
This skill appears to do what it says: generate V8 heap snapshots and record perf_hooks-based profiling locally. Before installing, note that: 1) it creates ~/.openclaw/heap-snapshots/ and ~/.openclaw/profiles/ and stores potentially large .heapsnapshot files—delete them after analysis; 2) it reads low-level process info (internal Node APIs and /proc/self/fd on Linux) to build diagnostics — expected for profiling but it does access process state; 3) SKILL.md and the code disagree about the output path (memory/perf/ vs ~/.openclaw/...), so confirm where files will land on your system; 4) there are no network calls or credential requests, so no outward exfiltration is apparent. If you run this on a production agent, consider running it in a controlled/dev environment first and inspect the files it creates.
Capability Analysis
Type: OpenClaw Skill
Name: heap-dump
Version: 1.0.1
The skill bundle provides legitimate diagnostic tools for Node.js memory and performance analysis. The scripts `heap-dump.js` and `profiler.js` use standard Node.js APIs (v8, perf_hooks) to collect system metrics and generate heap snapshots, storing them locally in the user's home directory without any evidence of data exfiltration, remote execution, or malicious intent.
Capability Assessment
Purpose & Capability
Name/description describe heap snapshots and profiling; the included scripts implement exactly those features (v8.getHeapSnapshot, perf_hooks). There are no unrelated network calls or external service credentials requested.
Instruction Scope
SKILL.md instructs running the included scripts which is correct, but there are small mismatches: the README warns 'profiler output write to memory/perf/' while the code actually writes to ~/.openclaw/profiles/ and ~/.openclaw/heap-snapshots/. The scripts also read /proc/self/fd (Linux-only) and use internal Node APIs (process._getActiveHandles/_getActiveRequests) to collect diagnostics — these are diagnostic actions consistent with the stated purpose but they access low-level process state.
Install Mechanism
No install spec (instruction-only with bundled scripts). Nothing is downloaded or extracted from remote URLs; risk from install mechanism is low.
Credentials
The skill declares no required env vars or credentials and indeed needs none. It does rely on process.env.HOME to create ~/.openclaw/… directories; the skill did not declare those config paths in metadata, which is a minor inconsistency you should be aware of.
Persistence & Privilege
Skill is not always-enabled and is user-invocable only. It writes files under the user's HOME (heap snapshots, diagnostics, profile state/history) which is expected for a local diagnostic tool and does not change other skills or system-wide agent settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install heap-dump - After installation, invoke the skill by name or use
/heap-dump - Provide required inputs per the skill's parameter spec and get structured output
