ClaudeSense reads your local session logs and tells you how Claude is really performing — mood signals, health scores, prompt coaching, and cost tracking. Free. Offline. Nothing leaves your machine.
Claude Code is powerful — but it gives you no feedback on how well you're using it. ClaudeSense fills that gap.
The Anthropic dashboard shows a total. But which session cost $40? Which single prompt burned half your budget? Which model was overkill for what you asked? There's no way to know.
Editing files before reading them. Vague prompts that need three retries. Marathon sessions where quality slowly tanks. Nobody tells you — so the habits stick.
You don't know you're at 85% context until Claude starts forgetting your instructions from two hours ago. By then, you've wasted time and money on output you'll have to redo.
Every response gets a mood score. Watch frustration build, catch drift before it costs you a restart.
Tool call breakdown, read-before-edit ratio, and blind edit detection. Understand Claude's reasoning — not just its output.
ClaudeSense scores every prompt you send against 22 rules and 6 framework detectors — then shows you the pattern that's holding your sessions back. No extra work. It happens in the background, from your existing logs.
Tight, focused prompts. You know exactly what you want and you lead with the verb. Claude responds cleanly.
9 sessions used structured frameworks this week. Your correction rate is 12% below average.
A-F health grades per session, a 90-day activity heatmap, weekly spend totals, and per-turn cost breakdown — all inside VS Code, no browser tab required.
A built-in prompt composer in the activity bar. Type or paste a prompt, get a score in under 500ms. 22 rules, 6 framework detectors, 22 ready-to-use templates. All local, zero tokens.
Open the Lab ⌘ Shift LOne click from the VS Code Marketplace. No account, no configuration, no setup. Works the moment it's installed.
Your sessions appear instantly — graded, sorted, browsable. The status bar shows live context percentage while Claude Code runs.
ClaudeSense points to the exact habit pulling your health score down. Fix one thing. Watch the score move. Repeat.
ClaudeSense reads only your local ~/.claude/projects/ files — the same logs Claude Code already writes to your disk. No network calls. No telemetry. No tokens consumed by the extension itself. The only tokens you ever spend are the ones you send to Claude Code yourself.
~/.claude/claudesense-pricing.json — rates are per million tokens, and the file regenerates with sensible defaults if you delete it. Useful if you're on Bedrock or Vertex with different pricing.~/.claude/projects/. Other tools use different log formats or none at all.I built ClaudeSense because I kept losing track of what was actually happening inside my Claude Code sessions — not the output, but the process. How much context am I burning? Am I prompting well or just retrying? Is Claude reading files before editing them? The logs had all the answers. ClaudeSense makes them readable.
