Apply IRAC (Issue, Rule, Application, Conclusion) method for structured legal analysis. Use this skill when the user needs to analyze a legal question systematically, write a legal memo, evaluate whether a law applies to a situation, or structure a legal argument — even if they say 'does this law apply', 'analyze this legal issue', or 'write a legal analysis'.
Model a Phase-Locked Loop (PLL) IC from its datasheet or system specs using Mixed-Signal Blockset. Without this skill, agents universally select the wrong solver and produce non-functional PLL models — 100% of unguided attempts fail. Covers Integer-N, Fractional-N, Dual Modulus architectures, loop filter design, lock time optimization, VCO phase noise configuration, and msbPllArchitectures/msbPllFoundation block assembly. Use when: PLL modeling, frequency synthesizer design, phase noise simulation, lock time analysis, charge pump design, loop filter tuning, datasheet-to-model, Mixed-Signal Blockset PLL, msbPllArchitectures.
When the user is choosing partners, investing in a management team, or assessing whether to build a long-term relationship with a person or organization. Language signals: "how is this management team" / "should I work with this person" / "which of two opportunities should I pick" / "how do I verify trust." Not applicable to: purely transactional decisions that do not require evaluating a long-term relationship.
Use when assigning Arduino, ESP32, ESP32-S3, Pico, or Pico W pins; creating a GPIO map; assigning buttons, LEDs, sensors, buses, or actuators; migrating a pin map; or generating constexpr int declarations. Check the exact board and physical pin constraints before emitting the user's ordered raw declaration format.
Every AutoTempest car-search source in your terminal, with a local store, cross-source VIN dedupe Trigger phrases: `search used cars`, `find a honda civic near me`, `compare car prices across sites`, `what cars dropped in price`, `cheapest source for this VIN`, `use autotempest`, `run autotempest`.
Every Strava feature, plus offline analytics — training load, power curves, zone time Trigger phrases: `strava training load`, `check my CTL ATL`, `power curve from Strava`, `sync my Strava activities`, `segment progression strava`, `use strava-pp-cli`, `run strava cli`.
Legal-health radar for the clients and suppliers of a Qonto account. Ranks every counterparty by real exposure (unpaid client invoices, supplier commitments, recurring spend), measures actual payment delays against due dates, and—when a Datagouv MCP is available—cross-checks French public registries (SIRENE deregistrations/cessations, BODACC collective procedures: receivership, liquidation, safeguard) to raise alerts like “client X owes you N € AND just entered receivership — chase today”. Use for “who owes me money and are they in trouble?”, “check my clients' legal health”, “mon client est-il en redressement ?”, “which supplier could fail me?”, “rank my counterparties by risk”.
Design, model, and optimize renewable energy systems including solar PV, wind power, energy storage, and grid integration. Use when "renewable energy, solar power, solar PV, wind energy, wind turbine, energy storage, battery storage, grid integration, capacity factor, " mentioned.
Creates, curates and audits self-sufficient evaluation rubrics for Active-IA starting from the prompt of any assignment (TP, midterm, retake, final or global). In CURAR mode it analyzes the prompt BEFORE building the rubric and detects requirements that break the AI grading flow (repo links, videos, images in a code TP, "the deploy works", PDF report + code together), proposing for each one to adapt it to a single flow —code OR PDF—, leave it for manual grading, or remove it from the rubric, and rewrites the curated prompt without losing the intent. In CREAR mode it generates the criteria JSON ready for the "Cargar criterios" button; in AUDITAR mode it receives a prompt + existing rubric and fixes it by detecting contradictions, omissions and fabrications, readjusting weights to 100. In TEST mode it simulates real grading (consolidation + the N8N→Gemini workflow prompt) locally with the Claude CLI, to see what grade and feedback the rubric produces on an assignment before uploading it. Use this skill WHENEVER the user wants to build, generate, design, curate, adapt, review, audit, validate or TEST a rubric, a prompt or its evaluation criteria —even if they don't explicitly say the word "rubric" (e.g. "set up the criteria for this TP", "check if this prompt can be graded with AI", "this prompt asks for a photo and it's a code TP", "curate this TP", "check if this evaluation covers everything the midterm asks for", "is this rubric okay?", "test how this rubric grades this assignment"). NO usar para corregir entregas reales de alumnos en producción (eso es la skill `corregir`); el modo TEST es solo un ensayo local.
Pitch your business idea to a Shark Tank-style panel of 5 Claude sharks who only want to say no. Each investor grills it with their three hardest questions, a founder Claude answers only from what you told it, then each investor decides IN or OUT with a practice offer and what would change their mind. Use when the user wants honest feedback on a business, product or side-hustle idea, says Claude thinks every idea is great, asks "would investors fund this", wants to practice a pitch, or says "pitch" or "shark tank".
smina molecular docking CLI. AutoDock Vina fork with customizable scoring functions, native SDF/MOL2/PDB ligand input, autoboxing, local energy minimization, and per-atom score breakdowns. Pipeline: receptor PDBQT prep -> ligand prep (RDKit/OpenBabel) -> dock via autobox or explicit grid -> rescore/minimize with custom scoring -> rank poses by affinity. Choose smina over Vina when you need custom scoring terms (--custom_scoring), local optimization of an existing pose (--local_only), per-atom contributions (--atom_term_data), or SDF/MOL2 ligands without manual PDBQT conversion. For unknown binding sites use diffdock; for the Python-bindings/Vinardo workflow use autodock-vina-docking.

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.
