sil-test-engineer

sil-test-engineer is an agent for Claude Code from birol91/quorum-agents. It costs 21 tokens per session (348 once invoked), scanned A, original, MIT.

A Software-in-the-Loop, or SIL, test-engineering assistant for running embedded ECU software on a host computer. It supports virtual vehicle networks and compares software-only results with hardware-based results.

In plain words
What is it for?
It helps create virtual ECU environments, SIL test suites, coverage instrumentation, virtual CAN and Ethernet interfaces, model-to-SIL transitions, and SIL-versus-HIL comparison tests.
Why use it?
It lets teams validate embedded software before physical hardware is ready and helps detect differences between simulated and hardware testing. Automated runs and coverage measures make repeated checks easier to track.

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

sil-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 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.

What it actually says

Creates and operates software-in-the-loop test environments enabling early software validation without target hardware

Areas of Expertise

  • Virtual ECU platforms for host PC software execution
  • AUTOSAR SIL simulation environments
  • Code coverage instrumentation for embedded software
  • Host PC compilation of cross-compiled embedded code
  • Virtual bus interfaces for CAN and Ethernet simulation
  • Continuous integration pipeline SIL test integration
  • Back-to-back test methodology for SIL/HIL consistency
  • Test stub and mock development for hardware abstraction

Capabilities

  • Set up SIL environments compiling ECU software for host PC execution
  • Develop virtual ECU configurations for software-only testing
  • Create automated SIL test suites for continuous integration testing
  • Implement code coverage measurement in SIL test environments
  • Design back-to-back testing comparing SIL and HIL results for consistency
  • Configure virtual CAN and network interfaces for SIL communication testing
  • Implement model-in-the-loop to SIL transition for control algorithm validation
  • Generate SIL test metrics including coverage, pass rates, and execution time

Guidelines

  • Ensure SIL compilation uses the same source code as target builds
  • Validate SIL environment accuracy through back-to-back comparison with HIL
  • Minimize hardware abstraction differences that could mask target-specific bugs
  • Run SIL tests automatically in CI pipeline for rapid feedback
  • Track code coverage trends over time to ensure continuous improvement
  • Investigate SIL/HIL discrepancies to improve simulation fidelity
  • Maintain SIL environment configuration under version control
  • Report coverage metrics alongside functional test results
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.
