What it does

Openclaw Test Heap Leaks is an agent skill from SafeAI-Lab-X/ClawKeeper. Investigate pnpm test memory growth, Vitest worker OOMs, and suspicious RSS increases in OpenClaw using the scripts/test-parallel.mjs heap snapshot tooling. Use when Codex needs to reproduce test-lane memory growth, collect repeated .heapsnapshot files, compare snapshots from the same worker PID, distinguish transformed-module retention from real data leaks, and fix or reduce the impact by patching cleanup logic or isolating hotspot tests.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `agents/openai.yaml`).

It sits in Testing & QA, covering Unit testing. It works with pnpm and Vitest. The repository describes itself as: ClawKeeper: Comprehensive Safety Protection for OpenClaw Agents Through Skills, Plugins, and Watchers (aka The Norton for OpenClaw).

When your agent uses it

  • Codex needs to reproduce test-lane memory growth
  • Collect repeated .heapsnapshot files
  • Compare snapshots from the same worker PID
  • Distinguish transformed-module retention from real data leaks

Example prompts

  • “/openclaw-test-heap-leaks”

Requirements

  • Node.js

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Reproduce the failing shape first.
  2. Wait for repeated snapshots before concluding anything.
  3. Classify the growth before choosing a fix.
  4. Fix the right layer.
  5. Verify with the most direct proof.

What it can do on your machine

Read from SKILL.md and the folder at commit 69db077. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • node
    • pnpm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Openclaw Test Heap Leaks loads about 1.2k tokens when it runs. Until then it costs about 119 tokens; SKILL.md has 552 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~119
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 552 words (~1,204 tokens).

“Use this skill for test-memory investigations. Do not guess from RSS alone when heap snapshots are available.”
