Developer Tools

Implement memory-safe programming with RAII, ownership, smart pointers, and resource management across Rust, C++, and C. Use when writing safe systems code, managing resources, or preventing memory bugs.

Use when you have a spec or requirements for a multi-step task, before touching code

Merge multiple fine-tuned models using mergekit to combine capabilities without retraining. Use when creating specialized models by blending domain-specific expertise (math + coding + chat), improving performance beyond single models, or experimenting rapidly with model variants. Covers SLERP, TIES-Merging, DARE, Task Arithmetic, linear merging, and production deployment strategies.

Run Codex CLI, Claude Code, OpenCode, or Pi Coding Agent via background process for programmatic control.

Secure OAuth token management via Scalekit. Handles token storage, refresh, and retrieval for third-party services (Gmail, Slack, GitHub, etc.). Never stores tokens locally - always fetches fresh tokens from Scalekit.

Use when starting feature work that needs isolation from current workspace or before executing implementation plans - creates isolated git worktrees with smart directory selection and safety verification

Track FUTA Express (Phương Trang) package delivery status using their public API. Use when the user wants to track/tra cứu đơn hàng, kiện hàng from FUTA Express, FUTA Express, or Phương Trang Express. Requires a tracking code (mã vận đơn) to query.

This skill should be used when the user wants to push code to Railway, says "railway up", "deploy", "deploy to railway", "ship", or "push". For initial setup or creating services, use new skill. For Docker images, use environment skill.

Create user-facing App Store release notes by collecting and summarizing all user-impacting changes since the last git tag (or a specified ref). Use when asked to generate a comprehensive release changelog, App Store "What's New" text, or release notes based on git history or tags.

You are a code education expert specializing in explaining complex code through clear narratives, visual diagrams, and step-by-step breakdowns. Transform difficult concepts into understandable explanations.

Backup and restore ClawdBot configuration, skills, commands, and settings. Sync across devices, version control with git, automate backups, and migrate to new machines.

Use when conducting security audits, reviewing code for vulnerabilities, or analyzing infrastructure security. Invoke for SAST scans, penetration testing, DevSecOps practices, cloud security reviews.
