X (Twitter) data platform skill for AI coding agents. 122 REST API endpoints, 2 MCP tools, 23 extraction types, HMAC webhooks. Reads from $0.00015/call - 66x cheaper than the official X API. Works with Claude Code, Cursor, Codex, Copilot, Windsurf & 40+ agents.
Profiles CSV and spreadsheet exports before you trust them: infers column types and measures missing values, duplicates, mixed types, outliers, date format chaos, and key uniqueness with a tested Python script, then writes a prioritized data quality report with safe fixes.
Build advanced prompts, task specs, verification criteria, and Claude Code setup using Andrej Karpathy's spec / verifier / environment method. Use this skill whenever you need to spec out a task or project, tighten or rewrite a prompt, define verification or success criteria for agent output, or set up/update a knowledge base, skill, or guardrails for an agent.
Master skill for the CLAUDE.md lifecycle: create, update, and improve files using repo-verified data, with multi-module support and stack-specific rules.
Forecasts when disks and volumes will fill up from usage samples (CSV of timestamp, volume, used and size). Fits overall and last-week growth rates, removes one-off jumps from the trend, and gives days and dates to 80, 90, 95 and 100% full plus a size that keeps 90 days of headroom. Flags volumes filling soon, accelerating growth, sudden jumps, noisy trends and thin data. Includes a stdlib Python forecaster with --self-test.
