First-party customer data often lacks a clear, reusable audience plan. This skill turns approved CRM or GA4 exports into named seeds, exclusions, and funnel-stage targeting maps.

Platform reports can overstate conversions when several channels claim the same order. This skill matches conversion exports to an order-ID truth set and produces a normalized reconciliation view.

Paid-ad tests can produce misleading results when variables, thresholds, and decision ownership are unclear. This skill creates structured test plans and interprets exported results with separate statistical and practical-effect checks.

Simulated trading agents need consistent rules for turning market observations into documented decisions. This skill applies ICT/SMC structure, entry criteria, and risk limits to BTC/USDT backtesting workflows.

Traders need structured SMC analysis without manually checking every liquidity level. This skill converts local chart data into bias, entries, stops, targets, and risk warnings.

Machine learning projects fail when data, metrics, and deployment choices are unclear. This skill gives structured guidance for model planning, preprocessing, evaluation, and MLOps.

Manual file conversion is slow and easy to get wrong. This skill provides focused conversion guidance for documents, data files, and images.

Slow queries and weak indexes can make applications costly and unreliable. This skill guides SQL tuning, index design, caching, and N+1 fixes.

AI data projects need reliable indexing flows, custom transforms, and operational commands. This skill guides CocoIndex design, implementation, testing, and troubleshooting.

Twitter/X data collection can require asynchronous queries, session setup, and careful rate-limit handling. This skill provides documented twscrape workflows for searches, profiles, timelines, and local result exports.

Time-series data work needs correct schema, retention, and aggregation choices. This skill gives TimescaleDB reference guidance for PostgreSQL developers and database teams.

Crypto market data work is hard when exchanges use different feeds and formats. This skill guides Claude, Codex, and Claude Code through Cryptofeed setup, callbacks, channels, and backend choices.

CoinGecko integration work requires accurate endpoint, authentication, and rate-limit details. This skill provides organized reference material to plan and implement cryptocurrency market data features.

Claude Router users need a clear view of routing volume, exception handling, and estimated savings. This skill reads the local router stats file and presents concise usage analytics.

PDF workflows often require text, tables, forms, and page operations across inconsistent documents. This skill guides Claude, Codex, and Claude Code through practical PDF processing tasks.

Data often hides trends when it stays in tables. This skill guides chart selection, styling, and export for clear visual reports.

SQL teams often need reliable examples for common query patterns and performance decisions. This skill provides concise references for CTEs, window functions, joins, pagination, and indexes.

SQLite is simple, but production use needs safe connection, schema, migration, and async patterns. This skill gives Claude, Codex, and Claude Code practical templates for local persistence.

Structured configuration data can be hard to inspect across JSON, YAML, and TOML files. This skill guides jq and yq queries for extraction, filtering, conversion, and updates.

AI coding session histories are difficult to review in raw JSONL form. This skill converts Claude Code and Codex sessions into readable markdown and searchable indexes.
