Auto Repair Shop Operations

Provides benchmarks, compliance, technician pay, parts markup, KPIs, startup costs, and growth guidance for independent auto repair shop operations.

Security Scan

The skill is an instruction-only operational reference for auto repair shops and its requirements and instructions are consistent with that purpose; no unexplained credential or install demands are present.

Purpose & Capability

Name/description (auto repair shop operations) match the provided SKILL.md and README content. The skill is purely advisory (benchmarks, KPIs, compliance, costs) and does not request credentials, binaries, or config access. Note: the skill's provenance is unclear (source/homepage not provided and owner ID is opaque), which affects trust but not functional coherence.

Instruction Scope

SKILL.md contains static operational guidance, tables, and checklists. It does not instruct the agent to read local files, access environment variables, call external endpoints, or exfiltrate data. README contains links to external resources (afrexai-cto.github.io) but SKILL.md itself stays within the stated scope.

Install Mechanism

No install spec and no code files — instruction-only, so nothing is written to disk or downloaded. This is the lowest-risk install profile and is proportionate to the skill's advisory purpose.

Credentials

The skill declares no required environment variables, credentials, or config paths. That aligns with an informational/consulting skill and is proportionate.

Persistence & Privilege

always is false, user-invocable is true, and the skill does not request persistent system privileges. There is no indication it modifies other skills or system settings.

Scan Findings in Context

[no-findings] expected: The regex scanner had no code files to analyze (instruction-only skill). Absence of findings is expected for a purely textual guidance skill.

Assessment

This skill appears coherent and purely informational. Before installing or relying on it: (1) verify the publisher/website (provenance is unclear), (2) do not provide any credentials to the skill (none are required), (3) treat the external README links as third-party resources and review them separately (they may lead to paid products), and (4) verify regulatory figures (EPA/OSHA penalties, certification requirements) against official local sources before acting on them.

Complete operational reference for independent auto repair shops. Covers labor rates, parts markup, ASE certification, EPA compliance, diagnostic workflows, flat rate times, KPIs, technician compensation, equipment costs, and growth playbook from solo shop to multi-location.

When to Use

• Setting labor rates by region and service type
• Calculating parts markup strategy
• Planning ASE certification for technicians
• Ensuring EPA/OSHA compliance
• Tracking shop KPIs (productivity, efficiency, ARO, bay utilization)
• Hiring and compensating technicians
• Planning shop startup or expansion
