Repair malformed JSON before parsing downstream automations with jsonrepair
Use jsonrepair when an agent receives JSON-like output that is almost valid but still breaks parsers, such as trailing commas, missing quotes, or concatenated fragments. The agent’s role is to normalize the payload before validation or routing, not to replace real schema design.
Renovate Automated Dependency Update Bot and CLI
Renovate is an open source dependency automation tool that discovers package files and opens update pull requests across many ecosystems. This skill fits agents that need to plan, configure, or operate dependency update workflows in GitHub, GitLab, Bitbucket, or other supported s
Render HTML-native agent videos with slash-command workflows using HyperFrames
Use agent-facing HyperFrames skills to turn prompts, PDFs, CSVs, or repo context into editable HTML video compositions and rendered MP4 outputs.
Render git diffs as shareable HTML review reports with Diff2Html
Use Diff2Html when an agent needs to turn raw unified diffs into readable HTML artifacts for reviews, audits, or status updates. This is a rendering and packaging workflow, not a generic Git hosting, code review, or SCM platform listing.
Remove unused Rust dependencies before they quietly bloat builds and reviews with cargo-machete
Use cargo-machete when an agent needs to find and remove unused Rust dependencies before they keep inflating build time, review noise, and manifest drift.
Remove AI Writing Fingerprints from Draft Copy
Use humanizer to scan drafts for AI telltales, explain what sounds synthetic, and suggest grounded rewrites that preserve the original point. This is for cleanup and editing passes, not for generating copy from scratch.
Remotion React Video Generation and Rendering Framework
Remotion is a framework for making videos programmatically with React. It lets agents and developers generate branded videos, social clips, explainers, and template-based renders using code, reusable components, and a documented rendering toolchain.
Remotion Programmatic Video Creator
Create videos programmatically using React components with Remotion. Leverage web technologies like CSS, Canvas, SVG, and WebGL to build dynamic, data-driven video content with full JavaScript control over every frame.
Remote-control tmux sessions for interactive CLI agents
Lets an agent drive existing tmux sessions by sending keystrokes and scraping pane output, which is exactly what you need for interactive CLIs that cannot be handled as one-shot shell commands. Use it for session supervision and intervention, not for general terminal automation o
rembg AI Background Removal CLI and Python Library
rembg is a Python tool for automatic image background removal powered by AI models like U2-Net and SAM. It works as a CLI, Python library, HTTP server, or Docker container, supporting CPU and GPU acceleration for batch processing of images and video frames.
rehype Plugin-Based HTML Processor by the Unified Collective
rehype is a plugin-based HTML processing toolkit built on the unified ecosystem. It parses HTML into an abstract syntax tree, transforms it with composable plugins, and serializes it back — enabling programmatic HTML minification, sanitization, link rewriting, heading extraction,
Rehearse and run scripted terminal demos with realistic playback using doitlive
Play back a scripted terminal demo with controlled typing and pauses so talks, onboarding sessions, and trainings stay smooth.
Regression-test prompts, agents, and RAG outputs before shipping changes
Use promptfoo when an agent needs to evaluate prompt, agent, or RAG behavior against saved assertions before a change goes live. The value here is the repeatable evaluation workflow, not a generic AI tooling catalog entry.
Regression test LLM apps and agents with metrics, traces, and eval suites using DeepEval
Run repeatable eval suites against prompts, RAG pipelines, and agents so regressions surface before release.
Regex Pattern Test Suite Generator
Generates comprehensive test suites for regular expressions using Hypothesis property-based testing and re2 for safe evaluation. Creates positive/negative test cases, edge cases, and ReDoS vulnerability checks.
Regenerate repository config from a single project definition with projen
Use projen when an agent should synthesize and refresh repository boilerplate from one canonical project definition instead of hand-editing many config files.
Regenerate Helm chart READMEs from values and comments before release
Uses helm-docs to rebuild Helm chart documentation from Chart.yaml, values.yaml, and inline comments so README files stay aligned with the actual chart. The agent can run this before commit or release, then surface changed tables, missing descriptions, and documentation drift in
Refresh Cookiecutter-based repositories from their upstream template without losing local answers
Use Cruft when an agent needs to pull new changes from a Cookiecutter template into an existing generated repository without redoing the project from scratch. The agent tracks the template origin, previews the diff, applies the update, and preserves the repository's saved answers
Reformat Markdown files into a stable house style before review or migration
Runs mdformat to rewrite Markdown into a consistent CommonMark-oriented layout or check mode in CI. Use it when an agent needs deterministic Markdown diffs before review, migration, or bulk cleanup, not when it needs to generate new content or build a docs site.
Reduce agent token burn on repo-scale coding commands with the rtk CLI proxy
Use rtk when an agent keeps wasting context on noisy shell output from large repos and you need smaller command responses before the model sees them.
Redpanda Connect Declarative Stream Processor
Redpanda Connect (formerly Benthos) is a high-performance stream processor that connects data sources and sinks through declarative YAML pipelines. It supports hundreds of connectors and a built-in mapping language called Bloblang for data transformation.
Redocly CLI OpenAPI Linter and Documentation Generator
Redocly CLI is an all-in-one OpenAPI utility that lints, validates, bundles, and generates documentation from API descriptions. It supports OpenAPI 3.2, 3.1, 3.0, Swagger 2.0, AsyncAPI 3.0, and Arazzo 1.0 with customizable rulesets for API governance.
Redoc OpenAPI Documentation Renderer
Redoc is an open-source tool by Redocly for generating beautiful, three-panel API reference documentation from OpenAPI specifications. With 25,000+ GitHub stars and nearly 1 million weekly npm downloads, it is the most widely used API documentation renderer.
