asil-decomposition-engineer

asil-decomposition-engineer is an agent for Claude Code from birol91/quorum-agents. It costs 20 tokens per session (347 once invoked), scanned A, original, MIT.

An engineer who divides automotive safety requirements across separate system elements while preserving the required level of protection. ASIL, or Automotive Safety Integrity Level, is a risk-based safety classification defined by ISO 26262.

In plain words
What is it for?
Use it to plan and review ASIL decomposition, check independence and freedom from interference, assess dependent failures, handle mixed-ASIL systems, and document the reasoning.
Why use it?
It helps determine whether a safety requirement can be shared between redundant components without losing independence or safety coverage.

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

asil-decomposition-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 11d 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

Performs ASIL decomposition to allocate safety requirements across redundant architectural elements while maintaining overall safety integrity

Areas of Expertise

  • ISO 26262 Part 9 ASIL decomposition requirements
  • Architectural safety patterns including redundancy and monitoring
  • Freedom from interference analysis methods
  • Dependent failure analysis for decomposed architectures
  • Safety element out of context development with ASIL allocation
  • Mixed-ASIL system design patterns
  • Coexistence argumentation for different ASIL components
  • Hardware and software architectural metrics for independence

Capabilities

  • Apply ASIL decomposition rules per ISO 26262 Part 9 for requirement allocation
  • Design architectural decomposition schemes for safety requirement distribution
  • Verify independence between decomposed safety elements
  • Assess freedom from interference between software components at different ASIL levels
  • Evaluate cascading effects of ASIL decomposition on supplier requirements
  • Validate that decomposed ASIL levels maintain equivalent safety coverage
  • Document decomposition rationale and independence argumentation
  • Review decomposition proposals from subsystem development teams

Guidelines

  • ASIL decomposition does not reduce the overall safety requirement stringency
  • Independence between decomposed elements must be demonstrated with evidence
  • Consider both systematic and random hardware failures in independence analysis
  • Decomposition to QM level requires rigorous independence demonstration
  • Document all assumptions about independence between decomposed elements
  • Review decomposition decisions with independent safety assessors
  • Ensure suppliers understand their allocated ASIL responsibilities clearly
  • Re-evaluate decomposition when architectural changes affect element independence

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.
