Cost is auto-calculated for known models. Supported providers: anthropic, openai, google, mistral, deepseek. Codex models supported: codex-mini-latest, gpt-5.1-codex-max, gpt-5.1-codex-mini, gpt-5.3-codex. If a model is unknown, provide the cost parameter manually.
check_budget before expensive operationsUsers can view all session data in a web dashboard:
npx codesession-cli dashboard
For zero-config tracking, users can either:
cs run <command> — one command that starts a session, starts the proxy, runs the command, and shows a cost summary on exit. No separate terminals needed.cs proxy [--session name] — start the proxy and set ANTHROPIC_BASE_URL / OPENAI_BASE_URL to http://127.0.0.1:3739. All API calls are auto-tracked.The proxy binds to 127.0.0.1 only and never stores prompt text or API keys.
npx claudepluginhub brian-mwirigi/codesession-cli --plugin codesessionTrack session costs, set budget alerts, and optimize token spend. Use to check costs mid-session or set spending limits.
Generates daily cost reports for Claude Code usage including total spend, running sessions, token stats via claude-view MCP tools. Useful for cost, spending, budget queries.
Tracks tokens, analyzes caching behavior, identifies bottlenecks in tool usage, and estimates costs to optimize Claude Code session performance and efficiency.
