Langfuse SKILL.md

Langfuse skill is a ready-made coding-agent skill for managing Langfuse prompts, traces, and evaluations through natural-language instructions. Installed into agents such as Claude or Codex, it connects the agent to Langfuse so it can investigate production traces, identify issues such as unnecessary tool calls, retries, latency, and incomplete evaluation coverage, and propose approved changes. Langfuse describes the skill as part of its developer tooling alongside the Langfuse CLI and MCP server.

Langfuse CLI is a command-line tool for accessing Langfuse APIs from agent workflows, scripts, and CI/CD. It exposes Langfuse data and operations including traces, scores, datasets, and experiment runs, enabling coding agents and developers to investigate production behavior and evaluation results from the terminal.

Langfuse Workshop is a step-by-step learning resource about applying Langfuse across the AI engineering loop. It uses a small TypeScript Dad IT Support Agent, named Specs, to teach tracing agent steps, managing prompts, monitoring production behavior, building datasets, running experiments, and evaluating changes. The workshop includes self-guided learner lessons, instructor notes, preparation materials, checkpoint branches, a runnable sample application, and helper scripts; its material is maintained in the public langfuse/langfuse-workshop repository. The sample agent uses an OpenAI tool-calling loop with two local tools, and the monitoring exercises cover user disagreement and all-caps frustration. The workshop is licensed under MIT and recommends Langfuse Cloud because self-hosted instances may not match the features used in the lessons.

Skills is a command-line tool for the open agent skills ecosystem. It installs reusable instruction sets defined in SKILL.md files into supported coding agents such as OpenCode, Claude Code, Codex, Cursor, and others. The `npx skills` CLI resolves skills from GitHub, GitLab, other Git URLs, local paths, or direct file and archive URLs; lists available skills, selects individual skills, and installs them project-wide or globally by symlink or copy. It can also generate a prompt for a skill without installing it, launch a supported agent with that prompt, search for skills, update or remove installations, and create new SKILL.md templates. Skills use YAML frontmatter with a name and description, and the CLI discovers them in standard agent and repository skill directories. The project is licensed under the MIT License.

book-to-skill is an open-source agent skill that converts technical books, document folders, or collections of source files into a unified skill for GitHub Copilot CLI, Amp, or Claude Code. It accepts PDFs, EPUBs, office documents, plain text, folders, globs, and file lists; the videos also describe OCR support for scanned PDFs. The tool distills source material into structured knowledge rather than a single summary, extracting frameworks, decision rules, anti-patterns, and per-chapter Markdown files. It also generates a core SKILL.md with a chapter index, plus glossary, patterns, and cheatsheet files. Agents load the relevant chapter and supporting files on demand, allowing answers to be grounded in the source content without placing the entire book in the context.
