Use when learning Sverchok fundamentals or debugging node tree execution issues. Prevents the common mistake of expecting immediate execution (Sverchok uses deferred tree-level updates, not per-node). Covers node tree architecture, data flow, socket data cache, update triggers, and the 18+ node categories with 500+ nodes. Keywords: Sverchok, node tree, data flow, socket cache, update trigger, node categories, SverchCustomTreeType, parametric design, node execution, what is Sverchok, visual programming, node-based modeling.

Use when debugging Sverchok node code errors -- silent data corruption, missing updateNode callbacks, socket data mutation, or IfcSverchok entity management issues. Prevents the 17 most common Sverchok mistakes including wrong data nesting, forgetting deepcopy=True on sv_get() when mutating data, and missing updateNode on bpy.props. Covers diagnostic patterns and fixes for each error type. Keywords: Sverchok error, data nesting, updateNode, deepcopy, sv_get, socket mutation, IfcSverchok error, silent corruption, debugging, common mistakes, wrong output, data disappears, nesting mismatch.

Use when developing a custom Sverchok node -- creating new node types, packaging as addons, or integrating with BMesh. Prevents the critical mistake of not calling self.outputs[i].sv_set() with correct nesting levels (data silently wrong). Covers full node lifecycle, socket creation, property management, BMesh integration, and registration patterns. Keywords: custom node, SverchCustomTreeNode, sv_get, sv_set, node registration, BMesh integration, node lifecycle, custom Sverchok node, addon, make my own node, create Sverchok plugin.

Use when working with Sverchok-Extra (advanced geometry, SDF, surfaces, fields, solids), Open3d integration, or developing custom Sverchok extensions. Prevents the common mistake of importing sverchok_extra nodes without checking addon availability first. Covers extension development, registration, and advanced geometry operations. Keywords: Sverchok-Extra, SDF, surfaces, fields, solids, Open3d, point cloud, extension development, custom extension, advanced geometry, signed distance field, 3D scan, mesh from points.

Use when generating IFC files from Sverchok geometry using IfcSverchok nodes. Prevents the critical mistake of not understanding SvIfcStore transient file management (data is purged on every full tree update -- use use_bonsai_file to persist). Covers the 31 specialized nodes, two geometry conversion modes, the 6-step IFC generation workflow, and Bonsai integration. Keywords: IfcSverchok, SvIfcStore, IFC from Sverchok, geometry to IFC, Bonsai integration, transient file, use_bonsai_file, IFC generation, node-based BIM, parametric IFC, generate IFC from nodes.

Use when designing parametric AEC geometry in Sverchok -- structural grids, facade panels, parametric stairs, roof geometry, MEP routing, or terrain from data. Prevents the common mistake of not using matrix transforms for element placement (using vertex offsets instead, which breaks with rotation). Covers matrix-based transforms, Blender object integration, and data-driven geometry generation. Keywords: parametric design, structural grid, facade panel, stairs, roof, terrain, matrix transform, data-driven, AEC geometry, Sverchok parametric, generate stairs, create facade, parametric building.

Interactive daily standup/meeting update generator. Use when user says 'daily', 'standup', 'scrum update', 'status update', 'what did I do yesterday', 'prepare for meeting', 'morning update', or 'team sync'. Pulls activity from GitHub, Jira, and Claude Code session history. Conducts 4-question interview (yesterday, today, blockers, discussion topics) and generates formatted Markdown update.

Use when working with TopologicSverchok for building topology analysis -- CellComplex workflows, space adjacency graphs, dual graphs, or energy simulation preparation. Prevents the common mistake of using mesh-based operations for topology analysis instead of non-manifold TopologicSverchok operations. Covers CellComplex-based BIM workflows, room connectivity, and envelope analysis. Keywords: TopologicSverchok, CellComplex, adjacency graph, dual graph, topology, non-manifold, room connectivity, energy simulation, building envelope, daylight analysis, solar, space adjacency.

Use when automating Sverchok from Python -- creating node trees programmatically, connecting sockets, setting parameters, or running batch parametric studies. Prevents the common mistake of not calling process_from_nodes() after modifying parameters (tree won't update). Covers node creation, socket connections, parameter sweeps, and batch processing. Keywords: Sverchok API, programmatic, node creation, socket connection, batch processing, parameter sweep, process_from_nodes, automation, Python scripting, create nodes from code, automate Sverchok.

Use when Sverchok data looks wrong, vertices are flattened, or list lengths don't match. Prevents the #1 Sverchok error: wrong data nesting levels (vertices MUST be level 3 [[[x,y,z]]], edges level 2, matrices level 1). Covers nesting requirements for all data types and the 5 list matching modes (cross, repeat, cycle, match_short, match_long). Keywords: nesting level, data structure, list matching, vertices level 3, edges level 2, flatten, data corruption, Sverchok data, list length mismatch, wrong nesting, data too deep, flatten list.

Use when writing SNLite scripts, Formula Mk5 expressions, Profile Mk3 definitions, or embedding custom Python logic in Sverchok node trees. Prevents the common mistake of wrong socket declaration syntax in SNLite (must use specific type identifiers like 'v' for vertices, 's' for strings). Covers all scripting nodes, built-in aliases, special functions, and the template system. Keywords: SNLite, Formula, Profile, scripting node, SN Functor B, socket declaration, type identifier, custom Python, Sverchok scripting, write Python in Sverchok, script node, inline code.

Use when connecting Sverchok nodes, debugging socket compatibility errors, or choosing the right socket type. Prevents the common mistake of connecting incompatible socket types without understanding implicit conversions. Covers all 16 socket types (vertices, strings, matrices, curves, surfaces, fields), socket properties, and type conversion rules. Keywords: socket type, SvVerticesSocket, SvStringsSocket, SvMatrixSocket, socket conversion, compatible sockets, data processing flags, Sverchok sockets, connect different types, socket color meaning.

Refactor bloated AGENTS.md, CLAUDE.md, or similar agent instruction files to follow progressive disclosure principles. Splits monolithic files into organized, linked documentation.

Create API handoff documentation for frontend developers. Use when backend work is complete and needs to be documented for frontend integration, or user says 'create handoff', 'document API', 'frontend handoff', or 'API documentation'.

Generate architecture documentation using C4 model Mermaid diagrams. Use when asked to create architecture diagrams, document system architecture, visualize software structure, create C4 diagrams, or generate context/container/component/deployment diagrams. Triggers include "architecture diagram", "C4 diagram", "system context", "container diagram", "component diagram", "deployment diagram", "document architecture", "visualize architecture".

Use when the user asks to run Codex CLI (codex exec, codex resume) or references OpenAI Codex for code analysis, refactoring, or automated editing. Uses GPT-5.2 by default for state-of-the-art software engineering.

This skill should be used when creating a Claude Code slash command. Use when users ask to "create a command", "make a slash command", "add a command", or want to document a workflow as a reusable command. Essential for creating optimized, agent-executable slash commands with proper structure and best practices.

Create high-quality git commits: review/stage intended changes, split into logical commits, and write clear commit messages (including Conventional Commits). Use when the user asks to commit, craft a commit message, stage changes, or split work into multiple commits.

Create and evolve design systems with design tokens, component architecture, accessibility guidelines, and documentation templates. Ensures consistent, scalable, and accessible UI across products.

Structured approach to workplace conflicts, performance discussions, and challenging feedback using preparation-delivery-followup framework. Use when preparing for tough conversations, addressing conflicts, giving critical feedback, or navigating sensitive workplace discussions.
