ryoppippi/ccusage — A CLI tool for analyzing Claude Code/Codex CLI usage from local JSONL files.

Description and use

**Summary**
ryoppippi/ccusage is a TypeScript‑based CLI that parses local JSONL logs generated by Claude Code/Codex and produces concise usage statistics. It lets engineers quickly quantify prompts, token consumption, and success rates, helping to tighten development cycles and improve CI feedback.

**Value**
By turning raw Claude logs into actionable metrics, the tool reduces the manual effort required to audit AI‑assisted coding sessions, speeds up debugging, and provides data‑driven insights for cost‑control and productivity optimization. Teams can embed the CLI in local workflows or CI pipelines to surface usage patterns and anomalies in real time.

**Practical adoption path**

1. **Proof‑of‑concept** – Clone the repo, run the CLI on a sample JSONL file, and verify the output matches expectations.
2. **Documentation check** – Review the README for installation flags, output formats, and integration examples; adjust any missing steps for your environment.
3. **Pilot integration** – Add a lightweight script to your CI that invokes ccusage after each Claude‑Code run, storing the generated report as an artifact or posting it to a dashboard.
4. **Scale** – Wrap the CLI in a reusable npm package or Docker image, configure parameterized runs across multiple projects, and automate alerting on threshold breaches.

**Production readiness**
The project scores 75/100 and shows strong OSS health signals: 14 067 stars, 549 forks, recent commits (as of 2026‑05‑12), and active community interest. Its TypeScript codebase is well‑maintained, and the core functionality is self‑contained, making it suitable for a serious pilot. While the license, security posture, and maintainer responsiveness still require a final review, there are no major metadata risks, and the tool is ready for integration in production‑grade workflows after the brief proof‑of‑concept and documentation validation steps.

Problem

ryoppippi/ccusage helps engineers save time in daily development and review loops.

Outcome

High for an OSS candidate: recent activity, adoption, and ecosystem signals are strong enough for a serious pilot.

Workflow

• speed up developer workflows
• automate local engineering tasks
• improve CI feedback
