LLM & Agents

Advanced patterns for generating high-quality Claude Code commands. Used by /new-command.

Integration patterns and best practices for adding persistent memory to LLM agents using the Letta Learning SDK

This skill provides guidance for semantic similarity retrieval tasks using embedding models (e.g., MTEB benchmarks, document ranking). It should be used when computing embeddings for documents/queries, ranking documents by similarity, or identifying top-k similar items. Covers data preprocessing, model selection, similarity computation, and result verification.

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

This skill provides guidance for compiling software (particularly SQLite) with gcov code coverage instrumentation, installing to custom prefixes, and making binaries available system-wide. Use when tasks involve compiling C/C++ projects with coverage flags, installing software to non-standard locations, or ensuring PATH availability for installed binaries.

This skill implements test-driven development workflow using the red-green-refactor cycle. Use when building new features or fixing bugs that require test coverage. Framework-agnostic methodology that works with any testing framework and programming language. Triggers on requests to implement features using TDD, write tests first, or follow test-driven development practices.

Digital forensic skill for recovering passwords and sensitive data from disk images, deleted files, and binary data. This skill should be used when tasks involve extracting passwords from disk images, recovering deleted file contents, analyzing binary files for fragments, or forensic data recovery scenarios. Applies to tasks mentioning disk images, deleted files, password fragments, or data recovery.

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

Guide for Claude Agent SDK - build custom AI agents powered by Claude. Triggers on agent sdk, claude-agent-sdk, @anthropic-ai/claude-agent, build agent, programmatic agent, embed claude, custom ai agent, agent infrastructure. Covers installation, authentication providers, tool permissions, file-based configuration, and TypeScript/Python code examples.

Your guide to the marketing toolkit. Diagnoses where you are in your marketing journey and recommends the right skills, agents, and workflows to use next.

Use to audit test quality with Google Fellow SRE scrutiny - identifies tautological tests, coverage gaming, weak assertions, missing corner cases. Creates bd epic with tasks for improvements, then runs SRE task refinement on each.

Use when encountering bugs or test failures - systematic debugging using debuggers, internet research, and agents to find root cause before fixing

Run Claude Code in headless/programmatic mode for automation, CI/CD, and agent workflows. Use when user asks about headless mode, programmatic execution, scripting Claude, or automating Claude workflows.

Guidance for DNA assembly tasks including Golden Gate assembly, Gibson assembly, and restriction enzyme-based cloning. This skill should be used when designing primers for Type IIS restriction enzymes (BsaI, BsmBI, etc.), creating fusion proteins, or assembling multiple DNA fragments. Covers primer structure requirements, overhang design, and verification strategies.

Meta-skill for recognizing learnings, validating improvements, and contributing back to the collective knowledge base. Use when agents discover better patterns, find gaps in existing skills, or want to improve shared knowledge.

Validate skills against agentskills.io specification. Use when adding new skills to the marketplace, reviewing skill PRs, checking skill compliance, or running quality gates on skills. Validates frontmatter fields (name, description, license, compatibility, metadata, allowed-tools), directory naming, line limits, and structure.

Coverage Gaps audit worker (L3). Identifies missing tests for critical paths (Money 20+, Security 20+, Data Integrity 15+, Core Flows 15+). Returns list of untested critical business logic with priority justification.

Analyze test coverage, identify gaps, detect dead code, and improve test quality. Use when user asks to check coverage, review tests, find untested code, or improve test robustness.

Set up Claude Code cloud/mobile environments for AILANG development. Use when starting a new cloud session, when tools are missing (Go, make, gh), or when user says "setup cloud", "setup environment", or mentions mobile Claude Code.
