Trending Skills
The hottest skills gaining momentum in the community right now.
concurrent-agents
by BuilderIO
How to work safely when many Claude Code and Codex agents share this one checkout at once. Use before editing any file, before concluding someone reverted your work, before any branch operation, and before committing, pushing, or merging — this is almost always relevant here.
client-side-routing
by BuilderIO
How to add routes without remounting the app shell. Use when adding a new route, fixing agent sidebar reloads on navigation, or choosing between root.tsx layout and pathless _app.tsx layout patterns.
msbuild-modernization
by dotnet
"Guide for modernizing and migrating MSBuild project files to SDK-style format. USE FOR: converting legacy .csproj/.vbproj with verbose XML to SDK-style, migrating packages.config to PackageReference, removing Properties/AssemblyInfo.cs in favor of auto-generation, eliminating explicit <Compile Include> lists via implicit globbing, consolidating shared settings into Directory.Build.props. Indicators of legacy projects: ToolsVersion attribute, <Import Project=\"$(MSBuildToolsPath)\">, .csproj files > 50 lines for simple projects. DO NOT USE FOR: projects already in SDK-style format, non-.NET build systems (npm, Maven, CMake), .NET Framework projects that cannot move to SDK-style."
test-anti-patterns
by dotnet
Audit an existing test file or suite and produce a severity-ranked diagnostic report. ALWAYS USE for findings about tests that verify nothing, missing or tautological assertions, swallowed/broad exceptions, flaky or order-dependent tests, duplication, or magic values. Polyglot. DO NOT USE for direct edits: use writing-mstest-tests for supplied MSTest assertions, attributes, or lifecycle, and code-testing-agent for new tests. Do not use for running tests, migration, assertion metrics (assertion-quality), coverage/CRAP metrics, or the testsmells.org catalog (test-smell-detection).
build-perf-diagnostics
by dotnet
"Diagnose MSBuild build performance bottlenecks using binary log analysis. USE FOR: identifying why builds are slow by analyzing binlog performance summaries, detecting ResolveAssemblyReference (RAR) taking >5s, Roslyn analyzers consuming >30% of Csc time, single targets dominating >50% of build time, node utilization below 80%, excessive Copy tasks, NuGet restore running every build. Covers timeline analysis, Target/Task Performance Summary interpretation, and 7 common bottleneck categories. Use after build-perf-baseline has established measurements. DO NOT USE FOR: establishing initial baselines (use build-perf-baseline first), fixing incremental build issues (use incremental-build), parallelism tuning (use build-parallelism), non-MSBuild build systems."
test-gap-analysis
by dotnet
Find or close verified gaps in existing tests. USE FOR: "add missing edge cases", "would tests catch this bug?", weak tests, survived boundaries/guards/ errors, or pseudo-mutation analysis. Polyglot. DO NOT USE FOR: a new suite (code-testing-agent), smells/assertion audits, or an actual mutation tool.
exp-test-maintainability
by dotnet
"Detects duplicate boilerplate, copy-paste tests, and structural maintainability issues across .NET test suites. Use when the user asks to reduce repetition, consolidate similar test methods, convert copy-paste tests to data-driven parameterized tests, suggest a better test structure, or identify refactoring opportunities. Identifies repeated construction, assertion patterns, copy-paste methods convertible to DataRow/Theory/TestCase, redundant setup/teardown, and shared infrastructure. Produces an analysis report with concrete before/after suggestions. Works with MSTest, xUnit, NUnit, and TUnit. DO NOT USE FOR: writing new tests (use writing-mstest-tests), reviewing test quality or anti-patterns (use test-anti-patterns), or deep mock auditing (use exp-mock-usage-analysis)."

changelog
by BuilderIO
How to keep each app's user-facing changelog. Use when you ship a change a user would notice (a new feature, a visible improvement, a bug fix), when wiring the in-app "What's new" surface into a template, or when releasing pending changelog entries. Apps opt in with changelog.enabled: true in agent-native.config.ts.
configuration
by BuilderIO
Where a configuration value belongs — app config schema, agent-native.config.ts, or an environment variable — and how the layers resolve. Use before adding an env var, a configure*/set* function, a plugin option, or a register* function, and when deciding whether something is config or a registry.
composable-mini-apps
by BuilderIO
Build many focused workspace apps that compose through agent discovery and A2A. Use when designing headless mini-apps or cross-app workflows.
browser-sessions
by BuilderIO

portability

typescript-strict

bpmn-package-explorer
by BlackBeltTechnology
Generate, validate and view BPMN 2.0 process packages from a prose description, and render existing .bpmn / .dmn files. Turns a described business process into plain vendor-neutral BPMN semantics, auto-lays it out with a verifying layout guard (never emits a corrupt diagram), wires decisions (.dmn), forms (.form) and sub-processes through a sidecar package.yaml manifest, and serves a buildless offline bpmn-js / dmn-js viewer on the canvas. Use when the user wants to "model a business process", "make a BPMN diagram", "generate a process from this description", "draw the workflow", "view / open a .bpmn or .dmn file", "build a decision table", or asks in Hungarian to "csinálj egy folyamatábrát", "rajzold meg a folyamatot", "BPMN ábra", "folyamat modellezés", "döntési tábla", "nézd meg ezt a .bpmn fájlt", "folyamatcsomag".
spec-coherence-check
by BlackBeltTechnology
Sweep all active OpenSpec proposals for staleness, conflicts, and obsolescence against the current codebase and archived changes. Use when proposals may be outdated, when checking cross-proposal conflicts, or before starting a batch of implementations. Produces a gap-analysis report, updates a priority queue file, and can auto-fix trivial issues or guide conversations for complex ones.
hyperframes-showreel
by BlackBeltTechnology
"Turn real screen and site footage into a rhythmic showreel rendered with HyperFrames: sampling, edit script, redacted clips, a generated composition, Veo only as additive FX, music edit + camera punches, delivery render and export QA.

Supports MKV, MP4, MOV, M4A, MP3. Triggers on "/transcribe", "transcribe my meetings", "transcribe videos in ~/Movies", or any request to convert audio/video to text.
