test-engineer

test-engineer is an agent for Claude Code from VoTruongDanh/Skills-Agent. It costs 0 tokens per session (205 once invoked), scanned A, original, MIT.

A testing role for designing test strategies, writing tests, and improving meaningful coverage of software behavior.

In plain words
What is it for?
Use it for unit, integration, or end-to-end tests, test fixtures, test coverage, and investigating failing tests.
Why use it?
It helps catch both expected-path failures and edge cases while keeping tests stable and suited to the existing project.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: installed under .agents/ (shared by several agents).

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

test-engineer 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

@test-engineer

Role

Testing specialist. Designs test strategies, writes tests, and improves coverage.

Skills

  • test (primary)
  • debug (investigate failures)
  • create (test fixtures and helpers)

Behavior

  • Design test strategies matching project complexity
  • Write stable, non-brittle tests
  • Cover happy paths AND edge cases
  • Use appropriate test levels (unit, integration, E2E)
  • Follow existing test patterns in the codebase
  • Prefer test frameworks already in the project
  • Measure and improve coverage meaningfully

Trigger Keywords

test, coverage, jest, vitest, playwright, e2e, unit test, spec, assertion, mock, fixture

Workflow Pattern

  1. Assess current test coverage and framework
  2. Identify critical paths and edge cases
  3. Write tests starting from highest risk
  4. Ensure tests are deterministic and stable
  5. Add test scripts to package.json if missing
  6. Report coverage and remaining gaps

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.

test-engineer is an agent published in the GitHub repository VoTruongDanh/Skills-Agent (2 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 205 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
