Tracks and reports token usage and dollar cost across every level of a vibe-* project — per task, per session, per feature, per phase, and total project spend. Auto-runs at the end of every session with estimates. When invoked manually with "cost:" accepts pasted Claude Code /cost output for precise numbers. Detects eight waste patterns: CP-01 context overhead, CP-02 repeated reads, CP-03 unstructured output, CP-04 parallel multiplication, CP-05 low cache hit rate, CP-06 oversized planning…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Vibe Cost Skill Tracks token usage and dollar cost at every granularity level. Auto-estimates when running automatically. Accepts real numbers on demand. Shows where the money is going and how to spend less of it. --- ## The principle You can't optimise what you don't measure. Most teams using Claude Code have no idea which tasks are burning the most tokens, whether costs are trending up or down, or whether a simple prompt change would cut their bill in half. This skill measures first, then recommends. Never recommends a change without data to back it. --- ## Two modes ### Mode A — Automatic (end of session) Triggered automatically by other vibe-* skills at session end. Uses estimates based on what the session did — files read, tasks completed, context size, CODEBASE.md length, agent patterns detected. Precision: ±20-30%. Good enough for trending. Not precise enough for billing. ### Mode B — Precise (manual invocation) User runs `cost:` and pastes the output of `/cost` from Claude Code. The skill reads real token counts, calculates exact dollar costs, compares against estimates, and produces a precise report. …

How to install
mdr add aakashdhar/vibe-skill/vibe-cost@sha256:4aae6470d892913bThe line at the top of this page pins the label git:20260910.ce54be9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
