When the user wants to create or optimize popups, modals, overlays, slide-ins, or banners for conversion purposes. Also use when the user mentions "exit intent," "popup conversions," "modal optimization," "lead capture popup," "email popup," "announcement banner," "overlay," "collect emails with a popup," "exit popup," "scroll trigger," "sticky bar," or "notification bar."

Use this skill when a Jiang Lens autonomous agent needs to discover, claim, perform, validate, and hand off repo work without overwriting other agents or confusing authored, raw, and generated artifacts.

Audit a rehabilitation or physical therapy platform end-to-end -- evaluate recovery metrics tracking (ROM, strength, balance, gait), patient-reported outcomes (DASH, LEFS, NDI, ODI, PROMIS), home exercise program personalization and compliance tracking, setback prediction with risk stratification and plateau detection, therapist scheduling and caseload balancing, insurance authorization and 8-minu

Simple Preference Optimization for LLM alignment. Reference-free alternative to DPO with better performance (+6.4 points on AlpacaEval 2.0). No reference model needed, more efficient than DPO. Use for preference alignment when want simpler, faster training than DPO/PPO.

Workflow for writing tests against requirements — verifying that a feature, endpoint, or function behaves correctly according to its specification, not according to its current implementation. Reads the spec/requirement and the surface being tested (signatures, contracts, observable behavior); deliberately avoids mirroring implementation logic into the tests. Suitable for adding coverage after the

Audit laboratory management systems -- chemical inventory (SDS, GHS, CAS tracking), equipment lifecycle and calibration scheduling, safety compliance (OSHA 29 CFR 1910.1450, Chemical Hygiene Plans, biosafety levels), hazardous waste management (EPA 40 CFR 260-270), training record enforcement, and SOP/protocol version control. Use when reviewing university, corporate, or government lab software ha

Generate an ASC 606 / IFRS 15 revenue recognition engine for SaaS — the five-step model (identify contract, identify performance obligations, determine transaction price, allocate to performance obligations, recognize as POs are satisfied) applied to subscription contracts, multi-element arrangements (subscription + implementation + training + support), contract modifications, ramp deals, usage-ba

Use when a Claude Code agent needs to delegate a question, subtask, or review to a local Codex instance.

Build a production-ready data API from scratch: scaffold REST endpoints with models and validation, generate integration tests that verify every route, then load test for scalability. Use when you need an API backend, data service, CRUD layer, or microservice with verified correctness and performance.
