Write Rust that reads like Rust — iterator pipelines over index loops, From/Into over ad-hoc converters, derives over hand-written impls, newtypes over bare primitives. Use when writing new Rust, when reviewing Rust that reads like a translation from another language, or when the user asks how to make Rust code more idiomatic or less repetitive.
Reverse-engineer the hook from a viral Instagram Reel or carousel, given a URL or a pasted caption. Identifies which of the 10 canonical 2026 formulas it uses (number-first, contrarian, relatable, confession, listicle, before/after, myth-buster, framework, pattern-interrupt Reel, how-I Reel), explains why it worked, names the primary goal, and returns a blank template mapped to your topic. Use to learn from a post you admire. Not for writing your own (use ig-caption-writer or ig-carousel-planner).
Edit images on RunComfy — this skill is a smart router that matches the user's intent to the right edit model in the RunComfy catalog. Picks Nano Banana Edit (batch up to 20, identity-preserving default), OpenAI GPT Image 2 Edit (multilingual in-image text rewrite, multi-ref composition, layout precision), Flux Kontext Pro (single-ref high-fidelity local edit), or Z-Image Turbo Inpaint (mask-driven precise region edit). Bundles each model's documented prompting patterns so the skill gets sharper edits without burning iterations on the wrong model. Calls `runcomfy run <vendor>/<model>/edit` through the local RunComfy CLI. Triggers on "image edit", "edit image", "image-to-image", "i2i", "swap background", "remove object", "rewrite headline", or any explicit ask to edit a single or batch of images
Query and download NCI Imaging Data Commons (IDC) cancer radiology and pathology datasets via the idc-index Python client. No authentication required: the parquet index ships inside the pip wheel, SQL runs locally via DuckDB, and DICOM downloads stream from public S3/GCS buckets through s5cmd. Use sql_query() for DuckDB cohort selection, get_collections/get_patients/get_dicom_studies/get_dicom_series for hierarchical browsing, download_from_selection() for downloads, and get_viewer_URL() for OHIF/Slim links. Use pydicom-medical-imaging for local DICOM reading; histolab for whole-slide pathology preprocessing.
Audit an existing repository or multi-module subsystem for evidence-backed architecture improvements, rank bounded candidates, and present them in a visual HTML report with before-and-after diagrams and a top recommendation. Use when the user asks where architecture investment would pay off across a codebase, wants multiple architecture candidates ranked, or needs systemic coupling, shotgun-change, testability, or AI-navigability problems diagnosed. For one named module's responsibility, deepening, splitting, or contract use codebase-design; for a source-tree or package audit use structure-codebase; for an already-selected path whose success is an evidence-backed net-mechanism-reduction claim use reduce-system-complexity. This is audit-and-selection by default.
Install the base skills every agent should have, globally and in one command - /initialize itself (so it can be rerun), skill-manager, /show-me, /grill-me, /wait-what, /connect-tool, /use-style and /better, all from this kit - plus the settings that stop Claude Code and Codex from asking before each action, the cc / cx shortcuts, the usage band above the prompt in the Claude desktop app and the terminal status bar (context, cost, 5-hour and weekly limits), then asks the user which visual style they like and makes it the default for every file the agent creates. Use when the user types /initialize, sets up a new computer, says "installe les skills de base" or before setup-brain.
Instagram video downloader — paste an Instagram video link and get a watermark-free video download link with one click.

Use when adding Superwall to an Expo (SDK 53+) project, wiring placements/feature gating, managing users and subscription status, handling deep links/web checkout, integrating RevenueCat, or debugging native-module issues.
Investigates one CI failure to a verdict: whose fault it is, which commit caused it, who wrote that commit, and whether a fix has landed. Use for "who broke master", "why did this test fail in CI", "is this failure my PR or everyone", "is this test flaky or broken", "when did this failure start", "what is broken in CI right now", and "why did the merge queue kick my PR". Works from the engineering-analytics-broken-tests tool, the CI failure log tools, and two warehouse views: engineering_analytics_ci_failures and engineering_analytics_ci_job_history. Not for aggregate CI health, cost, or merge bottlenecks (use diagnosing-ci-and-merge-bottlenecks), and not for saved insights (use turning-engineering-analytics-into-insights)

Returns 5-10 concrete offer ideas with example CTA phrasings. Use when the user says their campaign "needs a hook", "needs an offer", "what can I give away", or when ICP onboarding flagged a missing lead magnet.
Links a PostHog error occurrence or session's errors to OpenTelemetry traces, logs with the same trace ID, and Session Replay. Use when the user asks for trace or span IDs on an error, same-trace logs, or backend traces for errors in a session. Starts from an occurrence UUID, session ID, or error tracking issue URL. For a general issue diagnosis or replay summary, use investigating-error-issue or investigating-replay.

Speed up local parfor, parfeval, or spmd by switching to a thread-based parallel pool. Trigger when a user describes slow or disappointing local parallel performance, even if they don't mention threads. Symptoms: parfor on a laptop/workstation is slower than expected or "only slightly faster than for"; parfor scales poorly with the number of workers; ticBytes/tocBytes, the Parallel Pool dashboard, mpiprofile, or system tools show large per-worker data transfer; large broadcast variables or sliced inputs make iterations slow; opening a process pool dominates a short workload; user mentions serialisation or data transfer overhead. Also trigger on any question about whether code or a function works on a thread pool. For non-pool MATLAB performance work (vectorisation, preallocation, profiling), defer to matlab-optimize-performance.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
