Technical Writing

Comprehensive testing strategies with Vitest, React Testing Library, and Jest. Use when writing tests for React components, hooks, and integration testing.

Sync AILANG documentation website with codebase reality. Use after releases, when features are implemented, or when website accuracy is questioned. Checks design docs vs website, validates examples, updates feature status.

Create AILANG design documents in the correct format and location. Use when user asks to create a design doc, plan a feature, or document a design. Handles both planned/ and implemented/ docs with proper structure.

Generate hierarchical AGENTS.md structure for codebases to optimize AI agent token usage. Use when creating AGENTS.md files, documenting codebase structure, setting up agent guidance, organizing project documentation for AI tools, implementing JIT indexing, or working with monorepos that need lightweight root guidance with detailed sub-folder documentation. Covers repository analysis, root AGENTS.md generation, sub-folder AGENTS.md creation, and token-efficient documentation patterns.

Use when creating or developing anything, before writing code - refines rough ideas into bd epics with immutable requirements

Create user-focused, SEO-optimized changelog entries for software releases. Use when writing release notes, version updates, product changelogs, or "what's new" documentation for developer tools.

Guides the creation of self-signed SSL/TLS certificates using OpenSSL, including key generation, certificate creation, combined PEM files, and verification scripts. This skill should be used when tasks involve generating self-signed certificates, creating SSL certificate infrastructure, or writing certificate verification scripts.

This skill guides writing Infrastructure as Code using OpenTofu (open-source Terraform fork). Use when creating .tf files, managing cloud infrastructure, configuring providers, or designing reusable modules.

Maintain README files with setup instructions, features, tech stack, and usage examples. Use when updating project documentation, adding new features, or improving onboarding.

Guidance for optimizing numerical linear algebra computations, particularly finding eigenvalues of small dense matrices faster than standard library implementations. This skill applies when the task involves performance optimization of matrix operations, beating numpy/scipy performance baselines, or writing high-performance numerical code with Cython/LAPACK.

Use when building Avo admin interfaces. Creates resources, actions, filters, and dashboards following Avo conventions. Fetches latest docs dynamically.

Write and run AILANG code with correct syntax. Use when user asks to write AILANG programs, fix AILANG syntax errors, run AILANG code, or needs help with AILANG syntax. Includes version checking, syntax validation, and common patterns.

Creates reference documentation structure + smart documents (ADRs/Guides/Manuals) based on TECH_STACK. Only creates justified documents (nontrivial technology choices). L2 Worker in ln-100-documents-pipeline.

Creates task management documentation (docs/tasks/README.md + kanban_board.md). L2 Worker in ln-100-documents-pipeline. Sets up Linear integration and task tracking rules.

Creates 4 root documentation files (CLAUDE.md, docs/README.md, documentation_standards.md, principles.md). L3 Worker invoked by ln-110-project-docs-coordinator.

Test implementation of thin router skill for DiPeO backend. Provides decision criteria and documentation anchors for FastAPI server, CLI (dipeo run/results/metrics/compile/export), SQLite schema, and MCP integration in apps/server/. Use when task mentions CLI commands, server endpoints, database queries, or MCP tools.

Use when creating new skills, editing existing skills, or verifying skills work - applies TDD to documentation by testing with subagents before writing

Top orchestrator for complete doc system. Delegates to ln-110 coordinator (project docs via 5 L3 workers) + ln-120-150 workers. Phase 4: global cleanup. Idempotent.

Create category-aware, AEO-optimized blog posts for Lightfast. Use when writing technology deep-dives, company announcements, or product launches.

Guidance for creating polyglot files that are valid in both Python and C. This skill applies when tasked with writing code that must be parseable and executable by both the Python interpreter and C compiler. Covers polyglot syntax techniques, testing strategies, and critical cleanup requirements.
