Recently updated open-source projects

SEO / AEO / GEO Content Review audits articles, guides, comparison pages, and listicles before they are published. It checks important claims against primary sources, maps search intent, examines extractability and citability, and applies SEO, E-E-A-T, helpfulness, originality, and review-content lenses. The output includes a scorecard, fact-check, lens-specific findings, and a prioritized action plan. It is an audit by default and rewrites only when requested.

exam-prep-guide-builder turns past exam PDFs into figure-rich study guides for quizzes, finals, certifications, and other tests. It clusters recurring topics, ranks their frequency across years, writes step-by-step solutions, and extracts diagrams or tables from typed and scanned pages. Optional lecture slides can be linked to the questions they teach. Answer sources and uncertainty are marked, and a verification script checks figures and dropped questions.

Launch a new coding-agent session in a chosen project, or fuzzy-search past Claude Code sessions by name, path, ID, or transcript text before resuming them. The terminal TUI and native macOS menu-bar app share one local configuration and avoid their own network calls. The GUI is ad-hoc signed rather than notarized, so macOS may require a manual first-launch approval.

xiaoer-artstudio-design packages the 小耳 Art Studio aesthetic as a methodology rather than a page template. Agents can load principles for whitespace, typography, palette, layout rhythm, hand-drawn SVGs, motion, and trilingual copy, plus machine-readable tokens and remix guidance. Optional interaction recipes cover a physics garden, spring-like text, and a pencil cursor, and the kit is portable across Claude Code, Hermes, other agent frameworks, or raw LLM prompts.

Search the JSONL conversation history stored under `~/.claude/projects/` and return matching user or assistant turns with surrounding context, timestamps, session IDs, and file paths. Filters can limit dates, context turns, snippet length, and result count, after which the selected session can be reopened with `/resume`. The Python tool runs locally without network calls or third-party dependencies.

Progressive Estimation sizes individual tasks or entire backlogs by accounting for agent rounds, integration work, human planning, review, and fixes. It produces PERT-based expected and committed estimates, confidence bands, token usage, and optional model costs, with formats for common issue trackers. Teams can calibrate future estimates against actual results. The project is still in early development, so formulas and defaults may change and should be treated as structured guidance rather than certainty.

Illuminate converts a research corpus, book, codebase, conversation archive, or specification into a single self-contained interactive HTML file. It extracts a structured argument, then presents the governing thought, supporting signals, keyboard navigation, focus mode, and signal view in a Swiss editorial layout that works offline without a server. The process has explicit gates, but the same model can still overrate its own checks.

Give the skill a character reference image, keywords, or an IP name to build a game-style video prompt pack. It produces keyframe image prompts, Seedance video prompts, a shot timeline, subtitle copy, and TTS narration, while keeping character anchors, HUD continuity, and opening-frame constraints aligned. It suits creators who want a repeatable starting package for gameplay-style AI video work.

The SUMIT / OfficeGuy skill helps Claude Code integrate Israel’s billing and accounting API in Next.js and TypeScript applications. It covers browser-side payments.js tokenization, server-only secret keys, integer enums, idempotent charges, invoice and receipt documents, recurring billing, CRM data, and webhook verification. References also cover Israeli VAT and allocation numbers. Because the API can evolve, the project recommends checking official documentation and using a dedicated test terminal before live money flows.

Read Arc and Zen session files to rebuild workspaces, nested folders, and pinned tabs, while converting Arc Favorites to Zen essentials; a Zen setting is required to share them across every workspace. The Python scripts run standalone or through a Claude Code skill and create backups. Zen must be fully closed first, Python 3.8+ and liblz4 are required, and bookmarks, passwords, history, and extensions need separate tools.

The plugin extracts scene-change keyframes, transcribes speech, and aligns both into timestamped summaries that Claude Code can use for later questions or implementation work. It can also produce a detailed walkthrough and a narration transcript. Setup requires Python, ffmpeg, and Whisper-related dependencies, and untrusted videos may carry prompt-injection risk.

JDfit compares a job description with a DOCX resume, scores match, quantified impact, structure, language, and ATS readiness, then edits the original document while preserving its layout. Every change receives a native Word comment describing the original text, revision, and rationale, and the tool saves both a backup and an annotated version. Missing evidence is flagged for the candidate instead of being invented.

The-Life-Edit turns Claude into a quieter thinking companion that draws out the user's own ideas instead of rushing to generate answers. Its think-with-you skill offers several ways into a conversation and leaves room for uncertainty, while its v6 materials are written mainly in Japanese. It is free, requires no external API, and includes no tracking.

The Xiaolu House CLI lets people or AI agents search resale homes, rentals, new developments, communities, transaction records, and schools from a terminal. Results can be filtered by city, area, rooms, price, size, direction, and other housing attributes. A Xiaolu House API key and default city must be configured before querying.

Animated Presentation Skill uses Remotion and OpenMontage to create narrated explainer videos with native UI recreations, word-level narration sync, subtitles, Portuguese versions, and sound design. It also documents visual QA and FFmpeg gotchas. The environment needs Node, ffmpeg, ImageMagick, sentrysearch, and OpenAI plus AssemblyAI credentials; the license is for internal or educational use.

LinkedIn Posting Skill turns LinkedIn publishing into a repeatable routine: choose one audience, earn the stop, earn the read, invite a reply, and stay present on schedule. It covers hooks, post structures, timing for global and Indian audiences, content pillars, a 30-day plan, and metrics. Its guidance cites the project’s listed 2026 sources, while actual reach still depends on the account and audience.

Use Consilium for decisions with real tradeoffs, such as launching, pivoting, hiring, or accepting a commercial deal. It structures Claude's response as five contrasting advisor roles, has them cross-review the arguments anonymously, and ends with a synthesized recommendation, the main disagreement, the cost of the choice, and a concrete first step. It is not intended for factual questions, routine writing, or simple summarization.

This Claude skill turns labeling requirements into frontline-ready AI annotation rules. It covers text, dialogue, reasoning, retrieval, preference data, and multimodal tasks, using a clarification phase followed by drafting and targeted iteration with thresholds, positive and negative examples, and edge cases.
