misra-automotive-c

What This Skill Does

The misra-automotive-c skill is a specialized static analysis agent designed to audit embedded C code against the stringent MISRA C:2012 standards. It acts as an automated safety auditor, parsing source files to detect violations of mandatory and required rules essential for automotive safety-critical systems. By evaluating code against MISRA benchmarks—such as rules governing memory allocation, control flow, type safety, and preprocessor usage—this skill ensures that software adheres to high-integrity industry standards like ISO 26262.

For every violation discovered, the skill provides a clear reference to the specific rule ID, identifies the ASIL classification impact, and generates a fully compliant code replacement. This automated approach helps developers reduce technical debt, prevent undefined behaviors, and streamline the certification process for embedded systems.

Installation

You can integrate this skill into your environment by running the following command in your terminal: clawhub install openclaw/skills/skills/budhadityarano/misra-automotive-c

Use Cases

This skill is perfect for:

• Pre-commit code reviews for safety-critical automotive embedded software.
• Refactoring legacy embedded C code to meet modern ISO 26262 compliance requirements.
• Auditing hardware abstraction layers (HAL) and driver code for MISRA rule adherence.
• Validating that interrupt service routines (ISRs) and memory-mapped register access patterns do not violate embedded system constraints.

Example Prompts

1. "Check this C code for MISRA C:2012 compliance and suggest fixes for any high-priority rule violations: [PASTE CODE]"
2. "Review the following function for ASIL-D safety. Does it violate any mandatory MISRA rules regarding pointer arithmetic or memory allocation? [PASTE CODE]"
3. "Is this interrupt handler MISRA-compliant? I'm concerned about the static variables and loop structures used here. [PASTE CODE]"

Tips & Limitations

• Context is key: Always provide the full function or header context, as the skill needs to see variable declarations and preprocessor definitions to accurately assess type models.
• Rule Limitations: While the skill covers the vast majority of MISRA C:2012 rules, always maintain a formal deviation document for required rules that cannot be met due to specific hardware constraints.
• False Positives: As an AI agent, it may occasionally flag stylistic code that adheres to the spirit of the rule but is technically non-compliant due to edge-case interactions; manual verification by a safety engineer is recommended for final sign-off.
