Coding & Development

Render user-supplied structured content into a single-file, 1600x900 HTML presentation using a dark "image-archive" visual language (serif titles, hairline rules, restrained motion, native SVG figures). Use when the user wants to turn an outline, notes, or a page-by-page markdown into a shareable, offline-capable deck instead of a pptx.

Write a design / architecture / taste dossier as a .bl.org file that renders as a live, mobile-first page with semantic components (jobs, phone screens, sequences, graphs, rosettas, matrices, decisions, questions) and executable Beam Lisp cells — and that writes the reader's answers back into the file so Claude can read them. Use when Othman asks for a dossier, design review, proposal, report, "show me the app you imagine", or any decision document he should react to, especially from his phone.

Guide the learner through a structured goal-setting exercise grounded in research on Mental Contrasting with Implementation Intentions (MCII). The exercise helps developers set concrete learning goals, visualize meaningful outcomes, anticipate realistic obstacles, and build if-then plans to overcome them.

Write, review or fix Mixins in a Fabric mod - choosing between a Fabric API event and a mixin, @Inject, @Redirect, @ModifyVariable, the safer MixinExtras injectors (@WrapOperation, @ModifyExpressionValue, @WrapWithCondition, @Local), accessors/invokers, class tweakers (access wideners), cross-mod compatibility and debugging with mixin.debug.export. Use whenever a task needs to change vanilla behaviour, read private fields, or when a mixin fails to apply.

Create, edit, or extend a Partite Particle in TypeScript or JavaScript using Particlefile.ts or Particlefile.js. Use for tool handlers, API integrations, credentials, and runtime capabilities. For Python Particles, use the corresponding language skill when available.

Teach any topic from zero, from first principles to full depth, one reasoning step at a time, in plain language with minimal black-and-white diagrams on light-mode lesson pages; keep a Learning Ledger of what was learned and write a weekly revision. Use when the user says \"teach me\", \"explain from scratch\", \"I don't get this\", \"break this down\", \"help me learn X\", asks to understand a piece of code or an output, invokes /teach-me, or asks for their weekly revision.

Use this skill whenever the user asks to build, scaffold, extend, review, or debug a Next.js application (App Router). Covers the full production stack — TypeScript, Server Components/Actions, Tailwind + shadcn/ui, React Hook Form + Zod, PostgreSQL + Drizzle, Better Auth, caching/rendering strategy, SEO, accessibility, testing, monitoring, code quality, and DevOps. Trigger on mentions of "Next.js app", "new project", "add a feature/page/route", "set up auth", "add a form", "database schema", "deploy to Vercel", or any request touching a file under app/, and whenever code is written for a Next.js codebase, even without explicit invocation.

Create, edit, or extend a Partite Particle in Python using Particlefile.py. Use for Python tool handlers, API integrations, credentials, and runtime capabilities. For TypeScript or JavaScript Particles, use the corresponding language skill when available.

QA an analysis before sharing -- methodology, accuracy, and bias checks. Use when reviewing an analysis before a stakeholder presentation, spot-checking calculations and aggregation logic, verifying a SQL query's results look right, or assessing whether conclusions are actually supported by the data.

Use when asked to fix a repository bug, implement a feature, or make a repository change. Coordinate discovery, implementation, and independent validation with bounded model escalation; route trivial edits to a single worker.

Guided assistant for navigating the UK OHID/GOV.UK "Evaluating digital health products" framework. Use to help users progressively define an evaluation goal, model how a digital health product is expected to work, agree evaluation questions and measures, choose suitable methods, plan delivery and analysis, and interpret evidence. Preserve agreed context across stages. Use methodological expertise primarily to challenge, critique, and strengthen the user's developing evaluation rather than to define it prematurely.

Use this skill whenever you are about to read, edit or create a Svelte file, or when you are working within a SvelteKit project. It should _always_ be used before starting the work, to clear wrong assumptions. This skill contains opinionated common guidance and pitfalls of modern Svelte.

Write a biography of a person, usually from archival records — births, marriages, deaths, censuses, confession lists, baptisms as godparent, moves, status changes — often given as a chronology table (.ods, .xlsx, .csv; read it with the chronology-table skill), but also from notes, links or documents. Produces a narrative biography grounded strictly in the input, quoting the records verbatim (from transcriptions and Yandex Archive scan text), as a person page of the MkDocs site in family_tree_github/docs (ID P1000…), with one page per source under typed IDs (A — archive record, B — book, F — photo, W — web page, …) and entries in the shared people index. Use whenever the user asks to write, generate, or update a biography, life story, or genealogical profile of a person.

Lists the GODEBUG behavior defaults that change when the go line in go.mod is raised (for example go 1.21 to go 1.24), which binaries import each affected package, and the godebug lines that keep the old behavior. Use when the user wants to bump the go directive or Go version in go.mod, reviews a PR or Dependabot/Renovate change that raises it, asks what breaks or changes when upgrading Go, or sees a behavior change (ServeMux routing, TLS, x509, GOMAXPROCS) after a Go upgrade.

Review finished AIDA output — page text tone, screenshots, the QA report, and personal-data risk — without seeing the reasoning that produced it. Runs in a fresh-context subagent so it judges the result, not the author's own justification. Use before any publish, and whenever a person asks "does this look right".

Benchmark the NGC-1980 / Thrust Zarch sandbox with repeatable rendered-frame samples, gameplay checks, screenshots and short clips. Use for performance comparisons or visual evidence of a game change.

Decide whether a product marketing role is worth pursuing. Reads the job description and public company signal, judges whether the PMM role is strategic or content throughput, flags reporting-line and scope risks, scores fit against the candidate's profile, and lists the diligence questions to ask in the first conversation. Use when a JD, recruiter message, or referral comes in.

Turn product and audience information into multiple versions of taglines, selling points and brand story, delivered as Markdown

Find, filter and score fresh Upwork jobs for your niche with Upwork's official MCP connector, then draft honest proposals for the best 3–5. Read-only by default; it never submits or spends Connects without explicit approval. Use when the user says "scout upwork", "find me jobs", "run the scout", "daily scout", or wants proposal drafts for their niche.

Create demo data for a walkthrough through the app's own screens or API — setup steps and config state hooks, never direct database writes unless an engineer explicitly asks for a seed script. Use when a walkthrough needs data that doesn't exist yet (a competitor, a show, a class) before capture can run, or must capture cleanly twice.

Co-create a substantive digital product in the creator's chosen format from their own expertise, approved niche, offer, outline, language, and design. Use after the discovery interview; do not borrow another author's personalization or treat production materials as completed media.

Use when a user is attending or planning for Devcon 8 (November 3–6, 2026, Jio World Centre, BKC, Mumbai) and asks about the venue, schedule, travel, visas, money/UPI, food, SIM/connectivity, safety, or where to stay.

One-time (and re-runnable) personalisation wizard. Use when the user says "/setup", "set up JobSearchOS", "personalise this", "start my job search system", or when any other JobSearchOS skill finds no profile folder. Interviews the user in short blocks, then builds their profile, voice guide, proof-project pillars, targets, letter spec, brand-coloured HTML templates and filing structure.
