Recently updated open-source projects

This repository currently packages a chemistry-toolkit skill for Claude Code and the Claude Agent SDK. It can render molecular structures with RDKit and 3Dmol.js, typeset equations with KaTeX and mhchem, balance and verify reactions, embed editable structure sketchers, and produce step-by-step problem layouts. The repo also documents symlink installation and .skill bundling.

Trigger Sessionclips during a Claude conversation and it selects useful lessons, shipped work, opinions, receipts, process notes, or funny moments, then drafts three to five short social posts with character counts. Each draft follows the rules in an editable voice.md file, while sessions containing credentials, unpatched vulnerabilities, private client work, or other flagged material are refused.

Use this Claude Code skill to search or fetch web pages through a local Tor daemon with a new SOCKS identity for each request, including DNS resolution over Tor. It fails closed when a site blocks Tor and never silently falls back to a direct connection. The curl-based workflow cannot render JavaScript, is slower than normal browsing, and should not be used for logged-in services.

qa-defect-report-writer converts anything from a one-line bug note to a wall of logs into a consistent defect report with reproduction steps, expected and actual results, severity, and priority. It separates multiple bugs and labels inferred or assumed fields so missing facts are visible instead of silently filled in. The Markdown output is formatted for issue trackers such as Confluence, Notion, GitHub, and Jira.

mj-agent expands one Midjourney prompt into ten raw variations or a single brace permutation that can be pasted into Discord for batch generation. It can also split oversized commands and compare prompt runs across model versions. The number of permutation jobs depends on the Midjourney plan, permutations require Fast mode, and the skill prepares prompts rather than creating images itself.

oss-due-diligence guides a four-phase assessment of open-source repositories and third-party dependencies: identity and license checks, adversarial review, operating posture, and incident response. It adjusts emphasis for project archetypes and includes shell scripts for dependency hygiene, risky patterns, secrets, and release signals. The methodology is explicit about what was checked and avoids treating a limited review as proof that a dependency is safe.

Use this skill when a converted or hand-built WordPress theme traps copy inside PHP templates and leaves forms or styling brittle. It guides Customizer refactors, high-priority CSS overrides, generator-script fixes, database-versus-template decisions, and form handoffs to contact pages or n8n. The approach relies on WordPress core rather than paid plugins or page builders and includes a small PHP brace-balance checker for safer edits.

Give the skill a local project path or repository and it analyzes the code, dependencies, and existing documentation before drafting a complete README. It can include badges, a quick start, architecture, comparisons, contributing guidance, and licensing, while omitting unnecessary sections for smaller tools. It also calls out missing assets such as banners, screenshots, or social previews.

crawl-budget-manipulation helps SEO teams plan experiments around low-competition, long-tail queries. It combines keyword grouping, repeatable content briefs, looped internal links, a publishing schedule, Search Console actions, and follow-up metrics for crawl and ranking changes. The method is aimed at new or moderately authoritative domains and explicitly excludes high-competition head terms; its outcome figures are reported expectations, not guarantees.

doc-audit compares documentation claims with package files, workspace configuration, paths, and other codebase facts to surface drift, contradictions, orphaned references, duplication, and bloat. It produces a prioritized report, walks the user through each finding, and applies only approved edits as atomic commits before optionally trimming CLAUDE.md. Report-only and resume modes make the exhaustive audit easier to review in stages.

session-tab-namer gives every new Claude Code session an immediate fallback label, then replaces it with a semantic name such as `build:*`, `research:*`, or `debug:*` once the objective is clear. It works across common terminal emulators and tmux, persists names for other tools, and uses a SessionStart hook whose installer requires jq.

secure-builder activates when a Claude Code task touches authentication, uploads, user-supplied URLs, secrets, deployment settings, Dockerfiles, CI workflows, dependencies, or pre-commit checks. It plans threats first, then applies patterns for password storage, validation, SSRF, file handling, cookies, token rotation, container hardening, CI permissions, and security tests. The skill can also guide a private-repository bootstrap with scanning and branch rules. Routine refactors, renames, and pure UI work stay outside its trigger scope.

Schema Detector fetches a single URL, extracts JSON-LD, Microdata, and RDFa, infers the page type, and runs twelve schema checks plus malformed-JSON detection. It returns deterministic JSON with findings ranked from P0 to P3 and maps each issue to one of Ygramul's seven SEO levers. The skill is deliberately single-page and does not edit schema or execute client-side JavaScript.

This migration skill parses .twb or .twbx workbooks and maps their data sources, calculations, parameters, filters, worksheets, and dashboard zones into dbt models and Lightdash YAML. It emits model, chart, dashboard, and migration-report files, while surfacing unsupported features before validation with Lightdash lint and chart smoke tests. It is for workbook migration, not for authoring new Lightdash content, administering Tableau Server, or handling Tableau Prep .tflx/.twfl flows.

claude-code-qc compresses the staging, commit, and push sequence into the /qc command while matching the repository's existing commit style. It stages named files, keeps hooks and GPG signing enabled, and refuses amend, no-verify, blind add-all, force-push, and AI attribution patterns. The first run may need to bootstrap GitHub CLI authentication through a browser.

Dorian reviews a codebase across ten technical-debt categories, assigns severity tiers, and returns prioritized findings with path-and-line evidence. It then maps those findings one-to-one onto a single character that falls from guardian to gothic horror, producing a model-agnostic image prompt. Paths, names, secrets, and internal URLs are scrubbed before the prompt is shown.

qa403-ubuntu-install-claude-skill provides a repeatable script, install guide, and Claude Code walkthrough for running QuantAsylum's QA40x Windows audio-analyzer software on Ubuntu with Mono. It covers dependencies, udev and libusb rules, Wine extraction, rendering workarounds, and QA403 connection troubleshooting, with tested paths for Ubuntu 20.04 and 24.04. The scope includes QA402/QA403 hardware and excludes macOS, the QA40x V2 branch, and ALSA playback setup.

Competiwatch is a Windows and macOS desktop application for manually recording Overwatch competitive matches and reviewing performance across a season. It can organize games by role, Battle.net account, and season while capturing details such as heroes, maps, teammates, party size, time, and result, then summarize patterns with charts and streak views. Match history can be imported or exported as CSV, and the Windows installer may trigger a SmartScreen warning because the app is unrecognized.
