Development

Record a narrated video of a feature running in the local dev app, for a PR or a stakeholder. Drives a headless Chrome over the DevTools Protocol so clicks and keystrokes are real, captures frames, and encodes an mp4 with no extra tooling installed. Use when the user asks to "record a video", "make a demo", "show this working", or wants a screen recording of a change.

Comprehensive technology stack evaluation and comparison tool with TCO analysis, security assessment, and intelligent recommendations for engineering teams

Comprehensive security engineering skill for application security, penetration testing, security architecture, and compliance auditing. Includes security assessment tools, threat modeling, crypto implementation, and security automation. Use when designing security architecture, conducting penetration tests, implementing cryptography, or performing security audits.

Comprehensive SecOps skill for application security, vulnerability management, compliance, and secure development practices. Includes security scanning, vulnerability assessment, compliance checking, and security automation. Use when implementing security controls, conducting security audits, responding to vulnerabilities, or ensuring compliance requirements.

Comprehensive fullstack development skill for building complete web applications with React, Next.js, Node.js, GraphQL, and PostgreSQL. Includes project scaffolding, code quality analysis, architecture patterns, and complete tech stack guidance. Use when building new projects, analyzing code quality, implementing design patterns, or setting up development workflows.

This skill should be used when the user asks to "design system architecture", "evaluate microservices vs monolith", "create architecture diagrams", "analyze dependencies", "choose a database", "plan for scalability", "make technical decisions", or "review system design". Use for architecture decision records (ADRs), tech stack evaluation, system design reviews, dependency analysis, and generating architecture diagrams in Mermaid, PlantUML, or ASCII format.

Comprehensive code review skill for TypeScript, JavaScript, Python, Swift, Kotlin, Go. Includes automated code analysis, best practice checking, security scanning, and review checklist generation. Use when reviewing pull requests, providing code feedback, identifying issues, or ensuring code quality standards.

One-shot CatGo DAG workflow construction. Use whenever the user asks to "create a workflow", "build a pipeline", "set up CO2RR/OER/HER/NEB/DOS/slow-growth", "make a workflow for X reaction", or any catalysis pipeline involving structure_input → calculation → analysis. Skips the exploration phase (avoids listing node_types / templates / node_details repeatedly) and goes straight to a single `catgo_workflow create` + `batch` round-trip with the full graph_json. Triggers in Chinese on 创建工作流, 建立工...

VASP single-point energy calculation. Used standalone, as a pre-step for DOS/band structure, or to evaluate energy at a fixed geometry.

VASP geometry optimization (relaxation). Handles bulk, slab, and adsorbate-on-slab scenarios with correct ISIF, frozen layers, and convergence settings.

Ab initio molecular dynamics (AIMD) with VASP. NVT/NVE ensembles, temperature control, trajectory analysis.

VASP vibrational frequency calculation. Compute ZPE and thermodynamic corrections. Handles frozen atoms for slab systems with multiple freeze modes.

Density of states (DOS) workflow in VASP. Three-step process for accurate total and projected DOS, d-band center analysis.

VASP band structure calculation. Two-step workflow with SCF charge density followed by non-SCF band calculation along high-symmetry k-path.

Route VASP calculation requests to the correct task type. Enforces VASP-specific policies for POTCAR, ENCUT, k-points, and slab handling.

Diagnose and fix CatGo workflow engine errors including HPC connection failures, missing POTCARs, stuck tasks, and REMOTE_ERROR states.

Diagnose and fix common VASP errors including ZBRENT, BRMIX, EDDDAV, VERY BAD NEWS, POTCAR mismatch, and memory errors.

Validate an HPC/cluster configuration against the live cluster BEFORE submitting a VASP workflow, or diagnose why a remote job produced no output. Reads the user's submit script / run config, then calls the validate_hpc_config tool to probe the real cluster over SSH (POTCAR directories, per-element pseudopotentials, and VASP binary resolution under the real module-load + conda environment). Use whenever the user asks to "test my cluster config", "check if VASP will run", "verify my HPC setup"...

Routes troubleshooting requests to vasp_errors, convergence_issues, or workflow_errors sub-skills based on the type of problem.

Use when the user asks for systematic element substitution, combinatorial materials screening, high-throughput composition search, or multi-site replacement across different element groups.

Use when the user asks to generate a surface slab from a bulk crystal, specifying Miller indices, number of layers, vacuum thickness, or supercell size.

Use when the user asks to build a nanotube, roll up a 2D sheet into a tube, create a carbon nanotube (CNT), boron nitride nanotube (BNNT), or specify chiral indices (n, m).

Use when the user asks to create a moire pattern, twisted bilayer structure, magic angle graphene, or any twisted 2D heterostructure.

Use when the user asks to intercalate atoms or ions between layers, insert lithium into a cathode, or place species in interlayer gaps of a layered material.
