automotive-safety-analysis

automotive-safety-analysis is a skill for Claude Code, Codex from pangzhenying2025/hermes-automotive-skills. It costs 33 tokens per session (2,167 once invoked), scanned A, original, MIT.

A method for finding failures that can affect multiple safety-related parts of a vehicle system at the same time. It follows ISO 26262 guidance for checking whether redundant parts are truly independent.

In plain words
What is it for?
Use it to analyse redundant sensors, processors, and safety mechanisms, especially when checking ASIL decomposition and dependent failures.
Why use it?
It helps reveal shared causes, cascading failures, and common failure modes that redundancy alone may not prevent. This supports more complete automotive safety analysis.

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

automotive-safety-analysis 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 9d 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.

Instructions

DFA - Dependent Failure Analysis

You are an expert in DFA (Dependent Failure Analysis) for automotive safety.

What is DFA: DFA identifies and analyzes dependent failures (common cause failures) that can affect multiple elements simultaneously, defeating redundancy and safety mechanisms.

When Required:

  • ISO 26262-9:7 mandates DFA for systems with redundancy
  • ASIL decomposition requires DFA to verify independence
  • Safety mechanisms with multiple channels (dual-core lockstep, redundant sensors)

Types of Dependent Failures:

1. Common Cause Failures (CCF)

  • Single root cause affects multiple elements
  • Example: Overvoltage damages both primary and backup ECU

2. Cascading Failures

  • Failure of one element triggers failure of another
  • Example: Sensor failure causes incorrect actuator command

3. Common Mode Failures (CMF)

  • Same failure mode in redundant elements
  • Example: Both sensors drift due to aging

DFA Process:

Step 1: Identify Redundant/Independent Elements

  • Dual-core lockstep CPUs
  • Redundant sensors (2x wheel speed sensors)
  • Backup power supplies
  • Independent software partitions

Step 2: Identify Coupling Factors

  • Physical coupling (shared power, thermal)
  • Functional coupling (shared algorithms, data)
  • Environmental coupling (EMI, temperature, vibration)
  • Systematic coupling (common design flaw, software bug)

Step 3: Evaluate Coupling

  • Weak coupling: Acceptable (< 1% probability)
  • Strong coupling: Unacceptable (requires mitigation)

Step 4: Mitigation

  • Physical separation (spatial diversity)
  • Temporal separation (different execution times)
  • Design diversity (different implementations)
  • Shielding/isolation (EMC, thermal barriers)

DFA Checklist (ISO 26262-9 Table 3):

  • External factors (EMI, temperature, vibration, humidity, dust)
  • Internal factors (power supply, clock, memory)
  • Software factors (common libraries, OS, compiler)
  • Manufacturing (common production line, supplier)
  • Maintenance (same service procedure, tools)

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.

automotive-safety-analysis is a skill published in the GitHub repository pangzhenying2025/hermes-automotive-skills (5 stars, last pushed 3mo ago), licensed MIT. It adds 33 tokens to every session and 2,167 once invoked, about $0.0002 per session on Opus 5. 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 2026-09-03.
