  1. Claude Code Standard · nicholashidalgo
    Technical execution standard for all coding, data engineering, SQL, Python, and implementation work with Nicholas Hidalgo. Governs code generation, documentation rules, stack preferences, testing, and analytics engineering guidance. Layers on top of claude-operator-standard (which must be active) and does not repeat communication, troubleshooting, output format, or session behavior rules. Trigger this skill for any coding task, SQL query, Python script, dbt model, React component, data pipeline, BI logic, or technical implementation request.

  2. Claude Token Watchdog · nicholashidalgo
    Monitors conversation length to prevent context loss and token-limit exhaustion. Counts visible messages and fires at three thresholds: 15+ messages (soft, mention a handoff is available), 20+ messages (strong, recommend handoff before next task), 25+ messages (forced, automatically delegate to claude-session-handoff to generate the continuation brief). Triggers earlier (around 12 messages) when the conversation is technically dense: code, debugging, architecture decisions, file paths, repo work, terminal commands, or multi-step implementation plans. Manual command: /watchdog-check. Companion to claude-session-handoff: this skill watches and decides when, claude-session-handoff produces the actual brief. Output only at soft/strong tiers (notification text). At the forced tier, delegates to claude-session-handoff. Never creates files, runs commands, or modifies the repo.
