Optimize AI Costs with Audit-Usage Skill for Claude Code

Optimize AI Costs with Audit-Usage Skill for Claude Code

This skill enables users to effectively track and analyze the execution costs associated with AI projects developed using Claude Code by reading and consolidating audit logs. It provides insights into resources spent per skill, execution duration, failure rates, and permissions granted for each run. It assists in answering the question of a project's overall cost, which individual reports may not address.

What this skill does

• Reads execution logs written to .claude/audit-usage/ by the audit hook.
• Consolidates audit data across multiple runs, providing a summary of cost, duration, failure rates, and permissions involved in the execution of AI skills.
• Supports explicit invocation only; does not autonomously modify logs.
• Delivers all information in the same language as the reports, maintaining consistency.
• Instructs users on enabling the audit trail if it is initially unavailable, allowing them to set up the environment correctly.

Who it is for

• Developers using Claude Code who need to manage and optimize the financial aspects of AI project execution.
• Software teams looking for detailed reporting on AI agent activity and resource usage.
• Project managers requiring consolidated expenditure reports for budgeting and analysis.

Use cases

• Aggregating the cost associated with training and running AI models in a development environment.
• Analyzing execution failures to identify inefficiencies and optimize resource allocation for AI workflows.
• Tracking permissions granted during AI operations to ensure compliance and identify security-related issues.

Technical details

• Requires reading from .claude/audit-usage/ directory, which stores execution trails generated by ArchHook.java.
• Does not modify project code or log files; entirely read-only operation.
• Output is consistent with existing reporting language, suited for environments already using these logs.
• If audit files are absent, guides users to activate logging by setting up the necessary directory structure.
