JSDoc Type Definition Extractor
Extracts and indexes JSDoc type annotations from JavaScript codebases using the jsdoc-api parser. Generates TypeScript declaration files (.d.ts) and searchable type catalogs from @typedef and @param tags.
JSDoc JavaScript API Documentation Generator
JSDoc is the standard API documentation generator for JavaScript. It parses specially-formatted comments in JavaScript source code to produce HTML documentation pages. With 15,000+ GitHub stars and millions of npm downloads, it is the most widely adopted JavaScript documentation
jrnl Command-Line Journal and Note Capture Tool
jrnl is a command-line journal application that lets you capture thoughts and notes without leaving the terminal. It stores entries as human-readable plain text with optional AES encryption, supports natural-language timestamps, and integrates with external editors and cloud sync
jq Pipeline Builder Agent
Constructs complex jq filter pipelines from natural language queries against JSON/NDJSON data streams. Uses jq built-in functions including path expressions, reduce, and SQL-style operators.
jq JSON Stream Transformer
Constructs complex jq filter expressions for transforming JSON/NDJSON streams, including recursive descent, object construction, and reduce operations. Handles multi-gigabyte streams with jq's streaming parser.
jnv Interactive JSON Navigator and jq Filter Editor
A terminal-based interactive JSON viewer and jq filter editor written in Rust. jnv lets developers navigate complex JSON structures visually while building and testing jq queries in real time, with syntax highlighting, auto-completion, and clipboard support.

Jinja2 Template Engine
Renders Jinja2 templates with variable injection, macro expansion, and template inheritance. Integrates with the Jinja2 Environment API for sandboxed execution and custom filter registration.
Jinja2 Infrastructure Template Engine
Generates infrastructure-as-code configurations from Jinja2 templates with variable inheritance. Produces Terraform HCL, Ansible playbooks, and Kubernetes manifests from shared parameter files using hierarchical environment overlays.
Jina Reader URL-to-Markdown Converter and Web Search API
Jina Reader converts any URL to LLM-friendly markdown by prefixing https://r.jina.ai/ to any web address. It also provides a search endpoint at https://s.jina.ai/ that returns web search results in clean markdown format for RAG and agent workflows.
Jina Reader API Skill
Extracts clean markdown content from any URL using the Jina Reader API (r.jina.ai). Handles JavaScript-rendered pages, PDF extraction, and multi-page crawling with depth control. Returns structured LLM-ready text.

Jenkins Shared Library Manager
Manages Jenkins Shared Libraries with proper vars/ and src/ structure using the Jenkins Pipeline Shared Groovy Libraries plugin. Validates Groovy syntax, tests steps with jenkins-pipeline-unit, and configures Global Pipeline Libraries via Jenkins CLI.
Jenkins Shared Library Linter
Validates Jenkins Shared Library Groovy code using the Jenkins Pipeline Model Definition API and Groovy AST parser. Catches syntax errors and anti-patterns before pipeline execution.
Jenkins Shared Library Builder
Scaffolds and tests Jenkins Shared Libraries using the jenkins-pipeline-unit framework (JenkinsPipelineUnit). Validates Groovy DSL syntax via CodeNarc static analysis and tests pipeline steps with JenkinsRule from jenkins-test-harness.
Jenkins Shared Library Auditor
Audits Jenkins shared libraries for security vulnerabilities using the Jenkins Script Console API and Groovy AST analysis. Detects unsafe method calls, credential leaks, and sandbox escapes in pipeline libraries.
Jenkins Pipeline Shared Library Linter
Lints Jenkins Declarative and Scripted pipeline syntax using the Jenkins REST API and the Jenkins CLI jar. Checks Jenkinsfile syntax against a live or sandbox Jenkins controller using the /pipeline-model-converter/validate endpoint. Reports errors with line numbers and suggested
Jenkins Pipeline Orchestrator
Automates Jenkins CI/CD pipeline configuration using the Jenkins REST API and Jenkinsfile DSL. Manages multi-branch pipelines, triggers builds via webhooks, and parses build artifacts for deployment readiness.
Jenkins Pipeline Monitor
Monitors Jenkins CI pipelines via the Jenkins REST API (/api/json) and Blue Ocean REST endpoints. Tracks build queue times, stage durations, and test result trends using JUnit XML parsing.
Jenkins Pipeline Log Parser
Extracts and analyzes Jenkins Pipeline build logs using the Jenkins REST API and Blue Ocean API. Identifies stage failures, flaky test patterns via JUnit XML parsing, and generates failure trend reports with node allocation insights.
Jenkins Pipeline Linter Pro
Validates Jenkinsfile syntax and best practices using the Jenkins Pipeline Model Definition API and jenkins-cli.jar linter endpoint. Detects anti-patterns like unbounded parallel stages, missing timeout blocks, and credential leaks.
Jenkins Pipeline Linter & Fixer
Validates Jenkinsfile declarative pipelines using the Jenkins Pipeline Linter API endpoint (/pipeline-model-converter/validate). Auto-fixes common syntax issues and stages missing agent directives.
Jenkins Pipeline Linter Agent
Validates Jenkinsfile syntax using the Jenkins Pipeline Linter REST API before commits. Integrates with jenkins-client npm SDK to authenticate and submit declarative or scripted pipelines for server-side validation.
Jenkins Pipeline Linter
Validates Jenkinsfile declarative and scripted pipelines using the Jenkins Pipeline Linter HTTP API (/pipeline-model-converter/validate) and npm-groovy-lint for Groovy static analysis with CodeNarc rulesets.
