Implements the Syncfusion Blazor DataGrid (SfGrid) for efficient tabular operations such as sorting, filtering, paging, grouping, editing, aggregates, virtualization, lazy‑load grouping, and row or column spanning. Use this skill when building data‑grid workflows in Blazor Server, WebAssembly, Web App, or MAUI applications. Supports Excel/PDF export, virtual or infinite scrolling, customizable templates, and grid state persistence for consistent and optimized data‑grid behavior.
Live developer experience audit. Uses the browse tool to actually TEST the developer experience: navigates docs, tries the getting started flow, times TTHW, screenshots error messages, evaluates CLI help text. Produces a DX scorecard with evidence. Compares against /plan-devex-review scores if they exist (the boomerang: plan said 3 minutes, reality says 8). Use when asked to "test the DX", "DX audit", "developer experience test", or "try the onboarding". Proactively suggest after shipping a developer-facing feature. (gstack) Voice triggers (speech-to-text aliases): "dx audit", "test the developer experience", "try the onboarding", "developer experience test".
Codify the most recent successful /scrape flow into a permanent browser-skill on disk. Future /scrape calls with the same intent run the codified script in ~200ms instead of re-driving the page. Walks back through the conversation, synthesizes script.ts + script.test.ts + fixture, runs the test in a temp dir, and asks before committing. Use when asked to "skillify", "codify", "save this scrape", or "make this permanent". (gstack)
Tests API authentication mechanisms for weaknesses including broken token validation, missing authentication on endpoints, weak password policies, credential stuffing susceptibility, token leakage in URLs or logs, and session management flaws. The tester evaluates JWT implementation, API key handling, OAuth flows, and session token entropy to identify authentication bypasses. Maps to OWASP API2:2023 Broken Authentication. Activates for requests involving API authentication testing, token validation assessment, credential security testing, or API auth bypass.
Linear operators for large-scale inverse problems with matrix-free representations. Use when Claude needs to: (1) Define linear operators for forward/adjoint operations, (2) Solve inverse problems (deconvolution, imaging, tomography), (3) Apply signal processing transforms (FFT, convolution, derivatives), (4) Compose operators for complex workflows, (5) Perform regularized inversion with smoothness or sparsity constraints, (6) Process seismic or image data at scale.
Automate iOS/macOS App Store Connect workflows - TestFlight, builds, submissions, screenshots, and metadata with the asc CLI
Calculate present value, future value, NPV, IRR, loan payments, and amortization schedules across all compounding conventions. Use when the user asks about discounting cash flows, valuing an annuity or perpetuity, comparing investments with different timing, building a mortgage amortization table, or evaluating whether a project is worth pursuing. Also trigger when users mention 'what is it worth today', 'how much will I have in 20 years', 'monthly payment on a loan', 'discount rate', 'Gordon growth model', 'effective annual rate', 'continuous compounding', or ask how to compare a lump sum versus a stream of payments.
Performance analysis coordination workflow. Guides profiling delegation, bottleneck classification (compute/memory/launch/communication/sync), and structured report generation. Use when the user asks to analyze performance, profile a workload, check MFU/SOL, or diagnose bottlenecks.
Regression testing strategies for AI-assisted development. Sandbox-mode API testing without database dependencies, automated bug-check workflows, and patterns to catch AI blind spots where the same model writes and reviews code.
Interface with Gitea instances via the tea CLI. Manage repositories, issues, pull requests, releases, labels, milestones, CI/CD actions, webhooks, organizations, and notifications. Use when user mentions "Gitea", "tea CLI", or asks to create/list/edit/close issues, create/review/merge pull requests, manage repos, create releases, view CI/CD workflow runs, manage webhooks, track time, or perform any code hosting task on a Gitea server. Do NOT use for GitHub (use gh CLI) or GitLab.
Two-step workflow for creating quote posts on LinkedIn. Claude generates viral motivational quotes to accompany a caption, then produces a Gemini prompt that recreates a reference image with the chosen quote baked in. Use this skill whenever the user says "quote post", "quote graphic", "motivational post", "build me a quote", or wants a low-effort high-engagement LinkedIn graphic. Optimised for LinkedIn's employee and early-career audience, which skews toward motivational content.
Use when the user asks to "create a metric", "write a metric", "design a metric", "build a metric for", "evaluate agent performance", "measure call quality", "track a KPI", "add a workflow metric", "improve my metric", "fix a metric", "debug metric results", "set up quality scoring", or "what metrics do I need". Also relevant when discussing LLM judge prompts, custom code metrics, evaluation triggers, VALID_SKIP patterns, section extraction, or metric best practices for Cekura voice AI agents. Covers both creating new metrics and reviewing, iterating on, or troubleshooting existing ones.
