SkillKeeper monitors token usage for AI coding sessions directly from the menu bar. It provides session-by-session breakdowns showing which agents, skills, tools, and MCP servers executed and their associated token consumption, with alerts when a session becomes expensive.
Session-level tracking shows the detailed composition of each coding session: which skills were loaded, which tools were called, which MCP servers were queried, and the token cost of each component. This helps developers understand where token usage concentrates—whether in specific skills, long-running tools, or particular agents—and identify optimization opportunities.
Alert functionality notifies users in the menu bar when a session exceeds a cost threshold. Alerts link directly to the relevant code in the CLI or IDE, enabling quick navigation to the source of high usage.
Historical data covers 5 hours, days, weeks, and months in the paid version. The free trial limits history to the last 5–24 hours. Usage counters update in real time during active coding sessions.
Skill management features allow browsing and installing skills from the skills.sh store, editing skill files directly within SkillKeeper, pausing skills without uninstalling them, and viewing real-time usage counters per skill.
System requirements: macOS 13 or later. Works with Claude Code, Codex, Cursor, and Gemini CLI. Licensed for use on up to two Macs per purchase.
Pricing: 7-day free trial (limited history). Full version $19 one-time via Gumroad. No subscription required.
Limitations: The app’s value is proportional to AI coding tool usage; users who rarely use AI coding sessions will see limited benefit. The $19 purchase price may not justify the cost for light AI tool users. Skill management features are specific to Claude Code’s skills ecosystem.
Alternatives: Built-in usage tracking in Claude Code provides basic session cost information. UsageNow monitors token usage across multiple AI platforms. Moxie tracks usage limits across AI providers for account switching.
Suitable for developers using Claude Code or other AI coding tools heavily who want granular session cost visibility and skill management without switching to a separate dashboard.
