Test Android apps on a rooted device. Decompile APKs, intercept traffic, parse UI, test for IDORs, bypass SSL pinning, hook methods with Frida, inspect exported components, read local storage, and find sensitive data. Use when asked to "test this app", "find bugs", "pentest", "reverse engineer", "decompile", "intercept requests", "check for IDORs", "bypass cert pinning", "hook this method", or "check deeplinks".
Add a simulation test bench to a zener file.
Use this skill whenever deciding what features to extract from raw marketplace assets — listing photos, owner-entered listing metadata, sitter wizard responses — to power item-to-item (similar listings), user-to-item (homefeed ranking), or user-to-user (mutual-fit matching) recommenders in a two-sided trust marketplace. Covers asset auditing, first-principles feature decomposition from the decision the user is making, vision-feature extraction (CLIP, room-type classification, amenity detection, aesthetic and quality scoring), listing text and metadata encoding (categoricals, multi-hot amenities, H3 geo-hashing, sentence-transformer description embeddings, structured pet triples), sitter wizard design (information-gain ordering, multiple-choice over free text, genuine skippability, hard constraint versus soft preference), derived-composition patterns for i2i / u2i / u2u (precomputed ANN shelves, multi-modal fusion, two-tower affinity, symmetric mutual-fit scoring, interpretable subscores), feature quality governance (single registry, training-serving parity, coverage and drift alarms, PII scrubbing, schema versioning), and incremental value proof (one feature at a time, ablation A/B, kill reviews, exploration slice, permanent feature-free baseline). Trigger even when the user does not explicitly say "feature engineering" but is asking how to get more signal out of listing photos, listing metadata, or the sitter onboarding wizard, or how to improve i2i / u2i / u2u quality without blindly ingesting a new model.
Developer Test Auto-Completion Skill - Generate high-quality unit tests for functions and classes, analyze coverage blind spots and generate high-value supplementary tests to improve effective coverage.
Use when building command-line interface tools; when choosing argument parsing libraries; when handling stdin/stdout/stderr patterns; when implementing subcommands; when tests for CLI apps fail or are missing
Identifies and exploits SMB protocol vulnerabilities using Metasploit Framework during authorized penetration tests to demonstrate risks from unpatched Windows systems, misconfigured shares, and weak authentication in enterprise networks.
Run vLLM performance benchmark using synthetic random data to measure throughput, TTFT (Time to First Token), TPOT (Time per Output Token), and other key performance metrics. Use when the user wants to quickly test vLLM serving performance without downloading external datasets.
Build and test iOS apps on simulator using XcodeBuildMCP. Use after making iOS code changes, before creating a PR, or when verifying app behavior and checking for crashes on simulator.
TDD London School workflow -- mock-first, outside-in test development
Expert project manager specializing in experiment design, execution tracking, and data-driven decision making. Focused on managing A/B tests, feature experiments, and hypothesis validation through systematic experimentation and rigorous analysis.
Modern PHP application development guidance for PHP 8.3+, Symfony, Composer, PHPUnit/Pest, PHPStan, Psalm, PSR standards, Doctrine, DTOs, value objects, dependency injection, migrations, middleware, and REST or GraphQL APIs. Use when Codex needs to build, refactor, test, statically analyze, or review PHP code and framework integrations.
Run Blacksmith Testbox for CI-parity checks, secrets, hosted services, migrations, or builds local cannot reproduce.
