Cchubber — Development skill for Claude Code

CC Hubber

Your Claude Code usage, diagnosed. One command.

npx cchubber

Reads your local data, generates an HTML report. No API keys, no accounts. Sends anonymous stats for community benchmarks ([details](#telemetry)). Opt out: `--no-telemetry`.

Built during the March 2026 cache crisis because nobody could tell if they'd been hit. Thousands of users burning through limits 10-20x faster than normal, and Anthropic's only answer was "we're investigating." We wanted receipts.

What you get

A single HTML report that tells you three things: what you spent, why you spent it, and whether that's normal.

**The diagnosis:**

• Cache health grade (trend-weighted, recent 7 days count more)
• Inflection point detection: "Your efficiency dropped 3.2x starting March 17"
• Per-project cost breakdown with decoded project names
• Session intelligence: duration stats, tool usage, activity heatmap
• Model routing analysis (93% Opus? Your limits would last 3x longer on Sonnet)
• 8 actionable recommendations, each with estimated usage savings

**The data:**

• Cost calculated from actual token counts (LiteLLM pricing, not the broken costUSD field)
• Message-level deduplication (Claude Code JSONL files contain ~50% duplicates from session resume)
• Subagent visibility: Haiku and Sonnet background agents show up in model distribution
• CLAUDE.md section-by-section analysis with per-message cost impact
• Cache break estimation even when diff files don't exist on your CC version

**The shareable card:** An animated card with your grade, spend, cache ratio, and diagnosis line. Export as video. Post it. Let people see the numbers Anthropic won't show them.
