load-test-scenario-builder

load-test-scenario-builder is a skill for Claude Code, Codex from codebygarv/Ai-skills. It costs 28 tokens per session (352 once invoked), scanned A, original, MIT.

A builder of realistic performance and stress-testing scenarios using k6, Locust, or JMeter. These tools simulate many users performing actions such as browsing, signing in, searching, or checking out.

In plain words
What is it for?
Use it to create load-test scripts, traffic phases, virtual-user schedules, pass/fail response thresholds, and CI performance checks.
Why use it?
It helps reveal throughput limits, slow responses, database connection problems, and autoscaling issues before real traffic does. Realistic pacing and varied data make the results more representative.

Token cost

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

load-test-scenario-builder 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 5d 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.

What it actually says

Purpose

Create realistic, multi-phase performance and stress testing scripts modeling authentic user traffic patterns (browsing, authentication, cart checkout, search) with proper ramp-up and threshold gates.

When to Use

  • Benchmarking system throughput and maximum capacity limits.
  • Validating autoscaling triggers and database connection limits under load.
  • Setting up CI performance regression testing gates.

What to Analyze

  1. Traffic Profile: Ramp-up, sustained peak load, stress spikes, and ramp-down phases.
  2. User Journey Distribution: Weighted action ratios (e.g., 70% browse/search, 20% add to cart, 10% checkout).
  3. Think Time & Jitter: Realistic pauses between user clicks (e.g., sleep(random(1, 4))).
  4. Performance Thresholds (SLOs): Target response time percentiles (p95 < 200ms, error rate < 0.1%).
  5. Data Parameterization: Dynamic test data pools to avoid un-realistic cache warming on a single ID.

Output Format

  • Load Scenario Script: Complete k6 (JavaScript) or Locust (Python) script.
  • Execution Stages: Configuration of virtual users (VUs) and durations.
  • Threshold Definitions: Explicit pass/fail assertion rules.

Avoid

  • Hammering a single URL with 1,000 requests/sec with zero think-time (unrealistic traffic).
  • Omitting assertions on HTTP status and response payload validation.
Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
