agent-glovebox: Skill for Claude Code

.claude/skills/stress-test/SKILL.md

stress-test is a skill for Claude Code from AlexanderMattTurner/agent-glovebox. It costs 74 tokens per session (1,586 once invoked), scanned A, original, Apache-2.0.

A skill for creating smoke and stress tests for infrastructure such as sandboxes, containers, firewalls, and orchestration. Smoke tests check basic operation; stress tests probe behavior under demanding or failure-prone conditions.

In plain words
What is it for?
Use it to validate infrastructure configuration without Docker and to run live Docker-based checks of isolation, networking, entrypoints, and cross-platform setup.
Why use it?
It checks both configuration and real runtime behavior, helping expose setup and isolation problems that simple unit tests may miss. The approach covers Linux, macOS container environments, and WSL2.

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

stress-test scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Stress Test Skill

Generate smoke and stress tests for infrastructure components (sandbox runtimes, network isolation, container orchestration, entrypoint hardening, cross-platform setup). Prioritize end-to-end realism over unit-test purity — the goal is catching setup issues that surface on real platforms (Linux, macOS Colima/OrbStack, WSL2). Also fires on "make sure this works on macOS/Linux/WSL2".

General test-quality rules — test behavior not source text, non-vacuity, parametrize repeated patterns, no duplicate coverage, fixtures for repeated I/O — come from the writing-tests skill; follow it. This skill adds the infra-specific shape on top.

Principles

  1. Two tiers, always both. Static config validation (pytest, no Docker, runs everywhere) + live runtime checks (bash, needs Docker, proves isolation actually works).
  2. Assert the operation, not a keyword. assert "chown -R root:root" in content catches the real behavior; assert "chown" in content also matches a comment. Prefer the invariant/relationship (e.g. "proxy env vars reference the firewall's IP", read from both sides) over a hardcoded value that breaks on a legitimate config change.
  3. Guard empty-vs-empty. When comparing values that could be empty (namespace readlinks), assert non-empty first — an empty-vs-empty comparison silently passes.
  4. Bash checks are self-contained. Each check passes/fails/warns independently via a FAILURES counter, not set -e (which kills the whole script on one non-critical failure). Print PASS:/FAIL: prefixes for grep-ability.
  5. Test what breaks per platform. macOS: volume mounts (virtiofs/9p) and runtime install (Colima SSH). Linux: KVM availability and cgroup drivers. WSL2: nested virtualization.

Workflow

1. Identify the component and inventory existing tests

Determine what's under test (the sbx microVM launch and its kata runtime, the guest egress filter, entrypoint hardening, the host-side monitor and audit sink, setup scripts). Search tests/ and bin/check-*.bash for existing coverage and list it, so you extend rather than duplicate.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
