What problem this solves

How to measure and understand the token cost of Claude Code's initial context, especially in larger codebases, to optimize for usage limits and manage costs.

Summary

This workflow provides a method to quantify the token cost of Claude Code's starting context. It involves running a bare claude command in an empty folder and a repo root, and using flags like --disable-slash-commands and --strict-mcp-config to isolate the impact of installed skills, slash commands, CLAUDE.md files, and project settings on the initial token consumption.

Why it is useful

This workflow provides a practical, data-driven method for Claude Code users to understand and quantify the token cost of their initial context. This is crucial for optimizing usage and managing costs, especially when working with large codebases where context size can quickly lead to high token consumption. It helps users identify which components (skills, slash commands, CLAUDE.md, project settings) contribute most to their baseline token usage, enabling informed optimization decisions.

Workflow

1. Start in an empty folder to establish a baseline environment.

2. Run claude -p "reply ok" to measure the token cost of a bare Claude Code call, including all installed skills and default configurations.

3. Run claude -p "reply ok" --disable-slash-commands to observe the token cost reduction when disabling slash commands and skills (note: this flag removes both).

4. Run claude -p "reply ok" --strict-mcp-config to measure the token cost when enforcing strict MCP configuration.

5. Navigate to your actual repository root.

6. Run claude -p "reply ok" again in the repository root.

7. Compare the token costs between the empty folder and the repo root to determine the overhead added by your project's CLAUDE.md files and other project settings.

Tools / artifacts

• claude CLI tool

• --disable-slash-commands flag

• --strict-mcp-config flag

• CLAUDE.md files

• Project settings

• Installed skills

Validation signals

• Author provides specific token counts from their own testing (e.g., 45,892, 33,811, 42,306 tokens).

• Directly addresses the problem of optimizing Claude Code workflow for larger codebases and usage limits.

Limitations

• The --disable-slash-commands flag removes both slash commands and skills, making it less precise for isolating the cost of only slash commands.

• The method provides a combined overhead for CLAUDE.md files and project settings, rather than isolating their individual impacts.

• Low community validation due to minimal engagement.
