Find the open-source solution that fits.

github-flow-skill turns an explicit /github request into a structured collaboration flow: inspect the diff, create an issue, make a named branch, commit and push, open a linked pull request, and add a self-review comment. It stops before the irreversible merge so the user can inspect the link and diff, then squash-merges, deletes the branch, and closes the issue only after confirmation. An authenticated gh CLI is required, and ordinary Git commands remain untouched until invoked.

Personal Trainer skill combines evidence-based strength programming and nutrition guidance for one athlete. It can create RPE-based progressive plans, log sessions, track progress and plateaus, calculate calorie and macro targets, assemble practical meals, and retain the athlete profile in local files between conversations. The same knowledge base is exposed through Claude, Codex, Cursor, Gemini CLI, and other agents. It supports coaching workflows, while the athlete remains responsible for applying advice to their own circumstances.

Guardian helps AI-assisted developers investigate production failures by correlating stack traces, logs, Sentry issues, latency signals, and distributed traces into a timeline and likely root cause. It supports common language stacks plus Kubernetes, PostgreSQL, OpenTelemetry, and Datadog workflows, and explicitly names missing evidence when a conclusion cannot be verified.

X Copywriter is a multilingual skill for X content, account appeals, and pre-publication compliance checks. It drafts several hooks, tests the single point and intended action, then revises weak dimensions before delivery; a separate humanizer reduces generic AI phrasing. Appeal writing is constrained to verifiable facts and rejects invented excuses, making the workflow more disciplined than a generic copy prompt.

expense-reimbursement-skill reads receipt folders and reimbursement templates, backs up originals, classifies and renames materials, de-duplicates one expense into one ledger row, and fills a copy of the template chronologically. It reconciles totals and places unclear or unrelated items on an open-questions list, while keeping original files untouched and supporting invoices, PDFs, OFD, images, and spreadsheets.

video-bridge retrieves Bilibili subtitles when available and falls back to audio transcription, then turns short caption fragments into timestamped sections, full transcripts, and notes. SQLite FTS5 enables search across videos, with Obsidian-friendly Markdown as an option; subtitle access needs a logged-in session and fallback transcription depends on ffmpeg, yt-dlp, and podcast-bridge.

Seaworthy performs a static, no-network scan before deployment for common security mistakes in AI-built web apps, including exposed secrets, missing row-level security, unauthorized mutations, risky CORS, debug mode, open admin routes, and writable storage. It returns a ship-or-do-not-deploy decision with file-level findings; it is not a penetration test and primarily targets Next.js and Supabase scenarios.

Give Ultimate Idea Watcher a sentence, rough notes, screenshots, or an existing codebase, and it preserves the original idea while building a structured product brief around it. The skill researches the problem, users, and alternatives, defines the product architecture, then splits work into dependency-aware phases with ready-to-use designer and engineering prompts. It also maintains traceability and gap checks across security, privacy, accessibility, and later plan changes.

Start with confirmed bookings, scattered notes, or no reservations at all. The workflow compares route and pacing options, confirms the itinerary structure, then verifies time-sensitive details such as opening hours, fares, events, and transport before assembling a mobile-first single-file HTML handbook and printable version. Unbooked items remain clearly labeled, with a prioritized list showing what to reserve first.

Install repaint with `npx skills` and ask a compatible coding agent to build or redesign an interface. Its workflow researches real references, commits a concrete token system before markup, then renders the result and iterates through visual-slop, interaction, accessibility, and public-page SEO audits. The package is self-contained, with a curated reference library and 23 evaluations, and does not depend on other skills or agents.

handover-navigator reads documents, emails, notes, spreadsheets, and meeting records to create a handover summary, open-task tracker, first-30-day onboarding plan, and questions for missing context. It links each claim to a source, turns unknowns into questions instead of guesses, and normalizes inconsistent task states. Original material stays read-only while results go to a separate directory.

meeting-minutes-skill sends meeting audio to Alibaba Cloud OSS and Tongyi Tingwu for transcription and speaker separation, optionally extracts text from presentation files, and produces formal Chinese minutes with action items and review notes before exporting a Word document. It keeps the transcript as the factual source and warns against inventing names, budgets, or promises. OSS and Tingwu credentials are required.

claude-vastai-skill provides a Claude Code and terminal control plane for searching, renting, watching, using, syncing, and destroying Vast.ai GPU instances. Each rental can carry an auto-destroy deadline guarded by a watchdog, with cost and orphan checks; the CLI wraps the official Vast.ai tool and still requires an API key.

humanizer-fr rewrites pasted French text or a file to remove formulaic language-model habits, translated phrasing, and French typography mistakes. It adapts 33 patterns from the English humanizer and can calibrate the voice against a sample of the user’s own writing. The skill is prompt-only: it edits text but contains no executable code, making it suitable for Claude Code or OpenCode.

github-search-skill searches GitHub across repository, code, REST, GraphQL, and CLI angles to uncover useful projects that star rankings may hide. It includes a dead-end guide, code-search examples, and a batch shell helper with deduplication and rate-limit handling. The workflow uses GitHub’s official API rather than scraping and requires an authenticated gh CLI plus jq.

mask rewrites bland copy in the voice of a chosen character by drawing on linguistic fingerprints such as self-reference, catchphrases, sentence rhythm, and diction. You can use it for a pasted line or draft and switch among example voices such as Sherlock Holmes, Yoda, or Shakespeare. The goal is a consistent, recognizable character voice rather than a shallow word swap.

questionnaire-analysis-skill guides bilingual survey and scale research from questionnaire design and data cleaning through reliability and validity, group tests, regression, SEM, mediation, moderation, and APA reporting. It packages methodological references, result-sentence templates, checklists, and an offline threshold reference. The approach is tool-neutral but centers on SPSS and AMOS, with R examples for key steps.

claude-loop converts “make it better” into a project-specific scorecard and a repeatable cycle: score real signals, triage the weakest link, fix one slice, verify independently, and score again. Its init, score, run, and status modes keep the rubric and checkpoint state in .loop/. The loop stops after the target score is reached twice, with 90 as the default, instead of running indefinitely.
