Coordinates 9 specialized audit workers (security, build, architecture, code quality, dependencies, dead code, observability, concurrency, lifecycle). Researches best practices, delegates parallel audits, aggregates results into single Linear task in Epic 0.

Guidance for building and fixing Cython extensions, particularly for numpy compatibility issues. This skill should be used when tasks involve compiling Cython code, fixing deprecated numpy type errors, or resolving compatibility issues between Cython extensions and modern numpy versions (2.0+).

Builds interactive HTML presentation with 6 tabs (Overview, Requirements, Architecture/C4, Tech Spec, Roadmap, Guides). Creates presentation/README.md hub. L2 Worker under ln-100-documents-pipeline.

Guidance for implementing chess move generation using only regular expressions. This skill applies to tasks requiring encoding game logic (chess, board games) into regex patterns, or more generally "compile-to-constraints" problems where complex business logic must be expressed in a limited formalism like regex. Use when the task involves generating legal moves, validating game states, or transforming position representations using pattern matching.

This skill should be used when reconstructing PyTorch models from weight files (state dictionaries), checkpoint files, or partial model artifacts. It applies when the agent needs to infer model architecture from saved weights, rebuild models without original source code, or recover models from corrupted/incomplete saves. Use this skill for tasks involving torch.load, state_dict reconstruction, architecture inference, or model recovery in CPU-constrained environments.

Guidance for proving mathematical properties in Coq using induction, specifically addition commutativity and similar arithmetic lemmas. This skill should be used when working with Coq proof assistants to complete induction proofs, fill in proof cases, or apply standard library lemmas like plus_n_O and plus_n_Sm.

Guidance for reverse engineering graphics rendering programs (ray tracers, path tracers) from binary executables. This skill should be used when tasked with recreating a program that generates images through ray/path tracing, particularly when the goal is to achieve pixel-perfect or near-pixel-perfect output matching. Applies to tasks requiring binary analysis, floating-point constant extraction, and systematic algorithm reconstruction.

Build component-based UIs with ViewComponent and view_component-contrib. Use when creating reusable UI components, implementing slots and style variants, or building component previews. Triggers on ViewComponent creation, component patterns, Lookbook previews, or UI component architecture.

This skill guides writing cloud-init configurations for VM provisioning. Use when creating user_data blocks in Terraform/OpenTofu, or cloud-init YAML for AWS, DigitalOcean, GCP, or Azure instances.

Generate responsive, performant Tailwind CSS styles for React components. Use when styling components, building design systems, or implementing responsive layouts.

Guidance for transforming large text files (thousands to millions of rows) using text editors like Vim. This skill should be used when the task involves bulk text transformations, CSV manipulation, column reordering, regex-based find-and-replace operations, or when there are keystroke/efficiency constraints. Applies to tasks requiring macro-based editing, batch substitutions, or complex text processing where understanding the transformation pattern from input/output samples is needed.

Guidance for setting up Git-based multi-branch deployment systems with web servers. This skill applies when configuring Git repositories with post-receive hooks that deploy different branches to different directories, typically served by Nginx or Apache. Use for tasks involving SSH-accessible Git servers, branch-specific deployments, and web server configuration.

Write a HANDOFF.md file for another agent to continue the conversation. Use this skill when switching to a new conversation/session and need to pass context to the next agent. Triggers include "handoff", "write handoff", "create handoff", "pass to another agent".

Guidance for identifying and fixing security vulnerabilities in code. This skill should be used when asked to fix security issues, address CVEs or CWEs, remediate vulnerabilities like injection attacks (SQL, command, CRLF, XSS), or when working with failing security-related tests.

Generate type-safe AI content using Gemini structured output with Zod validation and Code Execution Tool. Use when building AI generation functions that need guaranteed output format.

Guide for performing linear cryptanalysis attacks on FEAL and similar Feistel ciphers. This skill should be used when tasks involve breaking FEAL encryption, recovering cipher keys using known plaintext-ciphertext pairs, or implementing linear cryptanalysis techniques. Applies to cryptographic challenges mentioning "linear attack," "FEAL," "Feistel cipher analysis," or key recovery from plaintext-ciphertext pairs.

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

Guidance for building Caffe from source and training CIFAR-10 models. This skill applies when tasks involve compiling Caffe deep learning framework, configuring Makefile.config, preparing CIFAR-10 dataset, or training CNN models with Caffe solvers. Use for legacy ML framework installation, LMDB dataset preparation, and CPU-only deep learning training tasks.

Enforce modern dashboard UI patterns with pill-shaped design, professional colour scheme, and typography standards. Use when building or reviewing UI components for the web application.

Use when creating Claude Code hooks - covers hook patterns, composition, testing, progressive enhancement from simple to advanced
