automotive-safety

automotive-safety is a skill for Claude Code, Codex from pangzhenying2025/hermes-automotive-skills. It costs 41 tokens per session (38,861 once invoked), scanned A, original, MIT.

Guidance for analysing and verifying functional safety in automotive systems under ISO 26262. It covers FMEA, FTA, and FMEDA, which are structured ways to examine failures and their effects.

In plain words
What is it for?
Use it for hazard analysis, risk assessment, safety-mechanism design, failure analysis, and safety verification and validation.
Why use it?
It helps teams identify hazards, trace failures through a system, and calculate safety-related hardware measures. This makes safety arguments and verification work more systematic.

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 scanned grade A with 1 finding 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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

Automotive Safety

Fmea Fta Analysis

FMEA/FTA/FMEDA Analysis for ISO 26262

Comprehensive guidance on Failure Mode and Effects Analysis (FMEA), Fault Tree Analysis (FTA), and Failure Modes, Effects, and Diagnostic Analysis (FMEDA) for automotive functional safety, including templates, calculation methods, and production-ready examples.

Overview

Analysis Types

FMEA (Failure Mode and Effects Analysis)

  • Bottom-up analysis: component failure → system effect
  • Identifies single-point and latent faults
  • Calculates diagnostic coverage
  • Required for all ASIL levels

FTA (Fault Tree Analysis)

  • Top-down analysis: hazardous event → contributing faults
  • Quantifies failure probability
  • Validates ASIL decomposition
  • Mandatory for ASIL C/D

FMEDA (Failure Modes, Effects, and Diagnostic Analysis)

  • Extension of FMEA with quantitative metrics
  • Calculates PMHF (Probabilistic Metric for random Hardware Failures)
  • Determines SPFM and LFM
  • Required for ASIL B/C/D hardware

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.
