Free open-source macOS cleaner built with SwiftUI — CleanMyMac alternative with zero telemetry, scheduled auto-cleaning, and Xcode/Homebrew/system cache cleanup.
Prepare and publish a research code repository for public release alongside a paper (arXiv, conference, GitHub). Use when the user wants to open-source code, create a GitHub release, package a code submission, make code public, or prepare a reproducibility release.
Vendor-neutral framework for scoring software health, estimating technical debt, assessing cloud readiness and open-source safety, and communicating quality to business stakeholders. Use when you need to quantify code health at the application or portfolio level rather than fix individual findings.
Generate and save images using Pollinations.ai's free, open-source API. No signup required. Supports URL-based generation, custom parameters (width, height, model, seed), and automatic file saving. Perfect for quick prototypes, marketing assets, and creative workflows.
Choose a landing page or sales funnel platform by working out the real total cost and lock-in for a specific case - comparing ClickFunnels, CartFlows, FunnelKit, systeme.io, GoHighLevel, Shopify apps, hand-rolled pages and self-hosted open-source options. Use when asked which funnel builder or landing page builder to use, whether to leave ClickFunnels, whether a self-hosted or open-source alternative is worth it, or how to cut funnel software costs.
Use when the user wants to build or tailor a resume, detailed interview resume, career master run, career coach, interview coach, career knowledge vault, Obsidian/LLM wiki, professional DOCX template, visual HTML/PDF resume, Canva-ready or Figma-ready resume, ATS/recruiter scorecard, cover letter, LinkedIn recommendations, interview prep, project interview briefs, technical-stack guide, job match scoring, redaction review, or career evidence summary from LinkedIn content, local project docs, Confluence, Jira, public GitHub, GitHub Enterprise, open-source work, profile pictures, or job postings. Trigger for resume drafting, tailoring, full career timeline, roles and responsibilities, impact metrics, ATS checks, keyword matching, DOCX generation, visual design tools, Canva/Figma handoff, browser/PDF rendering, project evidence extraction, recursive workspace analysis, durable career memory, tool auditing, job search, and interview prep.
Start-here router and tradecraft baseline for any OSINT investigation. Sets authorized scope, turns a vague request into an answerable intelligence question, writes a collection plan, picks the right workflow skill for the starting selector, and applies source grading and competing-hypothesis discipline. Use for "investigate this person/company/domain", "do OSINT on X", "where do I start", or any open-source intelligence, due diligence, or attribution task.
MATLAB and GNU Octave numerical computing for matrix operations, data analysis, visualization, and scientific computing. Use when writing MATLAB/Octave scripts for linear algebra, signal processing, image processing, differential equations, optimization, statistics, or creating scientific visualizations. Also use when the user needs help with MATLAB syntax, functions, or wants to convert between MATLAB and Python code. Scripts can be executed with MATLAB or the open-source GNU Octave interpreter.
Use this skill when working with SigNoz - open-source observability platform for application monitoring, distributed tracing, log management, metrics, alerts, and dashboards. Triggers on SigNoz setup, OpenTelemetry instrumentation for SigNoz, sending traces/logs/metrics to SigNoz, creating SigNoz dashboards, configuring SigNoz alerts, exception monitoring, and migrating from Datadog/Grafana/New Relic to SigNoz.
Design composable recommendation, ranking, and feed pipelines using the six-stage Source→Hydrator→Filter→Scorer→Selector→SideEffect framework popularized by xAI's open-sourced For You algorithm. Use this skill whenever the user is building any system that picks "the top K items for a (user, context)" — social feeds, content CMSs, RAG rerankers, task prioritizers, notification triage, search reranking, ad ranking.
Advises on Amazon RDS open-source engines (MySQL, MariaDB, PostgreSQL) for instance creation, upgrade planning, commitment pricing, proxy evaluation, and Blue/Green deployments. Handles any RDS MySQL, MariaDB, or PostgreSQL question, including create a production-ready RDS MySQL instance, provision an RDS PostgreSQL database, run the RDS upgrade advisor for my RDS MySQL instance, what are my upgrade options, upgrade RDS MariaDB from 10.6 to the latest version, should I buy reserved instances or a savings plan for db.r7g.2xlarge RDS MySQL, change a VARCHAR to INT column on RDS MySQL 8.0 with Blue/Green, and does RDS Proxy help when PgBouncer already runs in transaction mode. Covers instance creation with production best practices, describe-db-instances and describe-db-engine-versions upgrade-target workflow, live prechecks via SSM or direct connection, RI versus DSP commitment pricing, RDS Proxy versus PgBouncer, and Blue/Green lifecycle with binlog replay compatibility.
L3 Worker. Goal-based open-source replacement auditor: discovers custom modules (>100 LOC), analyzes PURPOSE via code reading, searches OSS alternatives via MCP Research (WebSearch, Context7, Ref), evaluates quality (stars, maintenance, license, CVE, API compatibility), generates migration plan.
