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

Guidance for creating polyglot source files that compile and run correctly as both Rust and C or C++. This skill applies when tasks require writing code that is valid in multiple languages simultaneously, exploiting comment syntax differences or preprocessor directives to create dual-language source files. Use this skill for polyglot programming challenges, CTF tasks, or educational exercises involving multi-language source compatibility.

Capture solved problems as categorized documentation with YAML frontmatter for fast lookup

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.

Coordinates project documentation creation. Gathers context once, detects project type, delegates to 5 L3 workers (ln-111-115). L2 Coordinator invoked by ln-100.

Run automated post-release workflow (eval baselines, dashboard, docs) for AILANG releases. Executes 46-benchmark suite (medium/hard/stretch) + full standard eval with validation and progress reporting. Use when user says "post-release tasks for vX.X.X" or "update dashboard". Fully autonomous with pre-flight checks.

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.

Use when writing or changing tests, adding mocks - prevents testing mock behavior, production pollution with test-only methods, and mocking without understanding dependencies

Use to expand bd tasks with detailed implementation steps - adds exact file paths, complete code, verification commands assuming zero context

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.

SQL query optimization patterns including EXPLAIN plan analysis, index strategies, query rewriting, and N+1 query prevention. Use when optimizing slow database queries, analyzing query performance, designing indexes, or debugging database bottlenecks. Works with PostgreSQL, MySQL, SQLite, and other SQL databases. Typical improvements: 10x-1000x query speedup.

Convert Obsidian WikiLinks ([[...]]) to standard Markdown links ([...](...)) for GitHub compatibility. This skill should be used when users need to make README files or other Markdown documents GitHub-compatible while maintaining Obsidian functionality, or when batch converting WikiLinks across multiple files.

Plan lifecycle management for Codex plans stored in $CODEX_HOME/plans (default ~/.codex/plans). Use when a user asks to create, find, read, update, delete, or manage plan documents for implementation work or overview/reference documentation.

This skill should be used when the user asks to search/send/draft email, check calendar, create events, schedule meetings, find/upload/share Drive files, read/edit Google Docs, read spreadsheet data, send texts/iMessages, send WhatsApp messages, send Signal messages, check messages, or create reminders. Manages Gmail, Google Calendar, Google Drive, Google Docs, Google Sheets, iMessage, WhatsApp, Signal, and Apple Reminders.

Use when querying Jira issues, searching Confluence pages, creating tickets, updating documentation, or integrating Atlassian tools via MCP protocol.
