Process-based discrete-event simulation framework in Python. Use this skill when building simulations of systems with processes, queues, resources, and time-based events such as manufacturing systems, service operations, network traffic, logistics, or any system where entities interact with shared resources over time.

Swift programming patterns for iOS and macOS

Use this skill when working with symbolic mathematics in Python. This skill should be used for symbolic computation tasks including solving equations algebraically, performing calculus operations (derivatives, integrals, limits), manipulating algebraic expressions, working with matrices symbolically, physics calculations, number theory problems, geometry computations, and generating executable code from mathematical expressions. Apply this skill when the user needs exact symbolic results rather than numerical approximations, or when working with mathematical formulas that contain variables and parameters.

Query the Cancer Dependency Map (DepMap) for cancer cell line gene dependency scores (CRISPR Chronos), drug sensitivity data, and gene effect profiles. Use for identifying cancer-specific vulnerabilities, synthetic lethal interactions, and validating oncology drug targets.

LibAFL is a modular fuzzing library for building custom fuzzers. Use for advanced fuzzing needs, custom mutators, or non-standard fuzzing targets.

MATLAB and GNU Octave numerical computing for matrix operations, data analysis, visualization, and scientific computing. Use when writing MATLAB/Octave scripts for linear algebra, signal processing, image processing, differential equations, optimization, statistics, or creating scientific visualizations. Also use when the user needs help with MATLAB syntax, functions, or wants to convert between MATLAB and Python code. Scripts can be executed with MATLAB or the open-source GNU Octave interpreter.

Interactive visualization library. Use when you need hover info, zoom, pan, or web-embeddable charts. Best for dashboards, exploratory analysis, and presentations. For static publication figures use matplotlib or scientific-visualization.

IBM quantum computing framework. Use when targeting IBM Quantum hardware, working with Qiskit Runtime for production workloads, or needing IBM optimization tools. Best for IBM hardware execution, quantum error mitigation, and enterprise quantum computing. For Google hardware use cirq; for gradient-based quantum ML use pennylane; for open quantum system simulations use qutip.

Memory health dashboard showing line counts, topic files, capacity, stale entries, and recommendations.

Atheris is a coverage-guided Python fuzzer based on libFuzzer. Use for fuzzing pure Python code and Python C extensions.

Backend development with Node.js, Express, NestJS, and server patterns

Constraint-based metabolic modeling (COBRA). FBA, FVA, gene knockouts, flux sampling, SBML models, for systems biology and metabolic engineering analysis.

Turn a proven pattern or debugging solution into a standalone reusable skill with SKILL.md, reference docs, and examples.

Spectral similarity and compound identification for metabolomics. Use for comparing mass spectra, computing similarity scores (cosine, modified cosine), and identifying unknown compounds from spectral libraries. Best for metabolite identification, spectral matching, library searching. For full LC-MS/MS proteomics pipelines use pyopenms.

Molecular featurization for ML (100+ featurizers). ECFP, MACCS, descriptors, pretrained models (ChemBERTa), convert SMILES to features, for QSAR and molecular ML.

Live application prep for Heath Barnett. Given a role name or a job application URL, renders the real application form, reads every field including the bespoke custom questions, drafts each answer grounded in Heath's receipts and resume master, and returns a copy-paste breakdown plus the submit window in the hiring manager's timezone. Built for the hot window: Heath is at the keyboard, this gets him ready to paste and submit in minutes. Trigger on "prep [company/role]", "apply prep", "get me ready to apply to [company]", "prep my application for [role]", "extract the questions for [role]", "what does the [company] application ask", or Heath pasting an application URL with intent to apply. Never submits the form. Never fabricates. No em dashes.

Coaching Analyst

Close out a work session safely. Verifies every change is committed, pushed, and green, confirms the work is live and verified, updates the notes for next time, and hands back a summary with links and a rollback path. Trigger on "close out the session", "wrap up", "lock it up", "are we good to close", "session QA", "end of session", or any moment before you stop or hand off.

Turn "is this deal real?" into a deal-by-deal risk verdict. An 8-state risk taxonomy, a qualification-vs-stage gap check, multi-thread coverage, days-dark per deal, and a commit-creep watch. Built for B2B sales teams, customizable to your CRM and your sales process. Trigger on "how are my deals", "which deals are stuck", "what's at risk this month", "is the rep sandbagging", "multi-thread check", or any open-deal diagnostic.

Turn "which leads should I work?" into a lead-by-lead work plan. Per-lead status (never-touched, engaged-not-replied, gone-cold, hot), days-dark per lead, last-touch quality, a re-engagement ranker, and a recommended next action for every lead. Built for SDRs and full-cycle reps, customizable to your CRM and your outreach tool. Trigger on "which leads should I work?", "who haven't I touched?", "show me cold leads", "hot leads to follow up on", "who's gone dark?", "re-engagement candidates", or any lead-level work-assignment question.

Turn a cold start into a warm one. Build a single orientation document for a project, account, or workspace, what it is, where things live, the decisions made so far, the open items, and the next move, so a new session or a new teammate is productive in minutes instead of days. Trigger on "get me up to speed", "onboard someone to this", "what's the context here", "brief a new session", "orient me on this account", or any cold-start on work already in motion.

Cut the Drag: give reps their selling time back

Run a real win/loss debrief on a single deal, not a shrug. It reconstructs what actually moved the deal, what nearly killed it, and the one repeatable lesson, then captures it so the next deal is run better instead of relearned the hard way. Built for B2B sales teams, customizable to your CRM and your deal process. Trigger on "debrief this deal", "why did we win", "why did we lose", "win/loss on this one", "what should we learn from this deal", or any single-deal retrospective.

Conversation Analyst

Cut the Fluff

Daily-Sales-Assistant

Turn churned and downgraded accounts into an early-warning system. Reads the customers who left or shrank, extracts the themes behind why, builds a warning checklist from the real causes, then reads your active book and flags which accounts look like the ones that just churned. Built for B2B retention teams, customizable to your CRM and your customer data. Trigger on "why do customers churn", "what do churned accounts have in common", "build me a churn early-warning list", "which accounts are at risk of churning", "who looks like a recent churner", or any retention post-mortem.

Stack the Tech: the right tech and the right signals

Turn "what should we pay reps and what number do we give them" into a defensible comp and quota plan. Reconciles a top-down number against a bottom-up build, sets the OTE mix, lays out accelerators, and names the behaviors the plan will drive and the ones it will break. Built for B2B sales leaders, customizable to your motion and your segments. Trigger on "design the comp plan", "set quotas", "what OTE should I pay", "reconcile top-down and bottom-up", "what will this plan actually incentivize", or any comp or quota build.

The pre-share gate for a Superhuman Docs (Coda) document. Before a doc reaches a reader, run the QA checklist, choose the interaction mode, set the publish frame, and confirm the share. Catches the broken formula, the wall of text, the orphaned bullet, the missing cover, the wrong audience. Trigger on "is this doc ready to share", "publish this doc", "QA this doc", "ship-check", "final pass before I send", "which interaction mode", or any moment a Superhuman Doc is about to leave the building.

Turn a new rep's start date into a ramp that ends in quota, not confusion. Builds a 30/60/90 onboarding plan with milestones at each gate, a certification bar they have to clear before they carry full load, and the manager touchpoints that catch a slow ramp early. Built for B2B sales managers and enablement, customizable to your role and motion. Trigger on "build an onboarding plan", "30/60/90 for a new AE", "how do I ramp this rep", "certification checklist", "onboarding milestones", or any new-hire ramp.

Close a work session without losing what just happened. Write a handoff brief that captures progress, the decisions you made, the unfinished items and their next steps, and the details that would evaporate overnight, then it asks whether to commit or save it, never automatically. Trigger on "wrap up this session", "write a handoff", "close out for the day", "hand this off", "what did we get done", or the end of any working session you might have to resume later.

Turn a cold dial into a conversation. A permission-based opener plus ready objection turns for "not interested," "no time," "just send me info," and "we already use X," tuned to one persona. Built for B2B SDRs and full-cycle reps, customizable to your persona, offer, and dialer. Trigger on "write a cold call opener", "give me objection responses", "handle 'not interested'", "cold call script for this persona", or any live-dial prep.

Walk into the negotiation with a plan, not a hope. Sets your walk-away and your target, builds the concession ladder (what you trade and what you get for it), maps their likely asks, and drafts the responses that protect price and terms. Built for B2B sales teams, customizable to your CRM and your deal process. Trigger on "prep me for this negotiation", "the prospect wants a discount", "what should I concede", "build my concession ladder", "hold price on a new deal", or any pre-negotiation planning.
