Automated code review and analysis
quantitative-analysis

nextjs-performance
by srbhr
Next.js critical performance fixes. Prevents async waterfalls, reduces bundle size, secures Server Actions, and ensures correct production builds. Use when writing React components, data fetching, Server Actions, or optimizing bundle size.
component-refactoring
by langgenius
Refactor high-complexity React components in Dify frontend. Use when pnpm analyze-component --json shows complexity > 50 or lineCount > 300, when the user asks for code splitting, hook extraction, or complexity reduction, or when pnpm analyze-component warns to refactor before testing; avoid for simple/well-structured components, third-party wrappers, or when the user explicitly wants testing without refactoring.
axiom-app-store-diag
by CharlesWiltgen
Use when app is rejected by App Review, submission blocked, or appeal needed - systematic diagnosis from rejection message to fix with guideline-specific remediation patterns and appeal writing
axiom-core-location-diag
by CharlesWiltgen
Use for Core Location troubleshooting - no location updates, background location broken, authorization denied, geofence not triggering
ux-ui-analyze-single-page
by raphaelmansuy
Analyze exactly one captured UI page (from ux_ui_map screenshots + request JSON) and immediately write/update ux_ui_map/pages/{page}.md in neutral descriptive language. Use when asked to analyze screenshots, rewrite corresponding analysis immediately, or avoid memory/context saturation.
axiom-cloud-sync-diag
by CharlesWiltgen
Use when debugging 'file not syncing', 'CloudKit error', 'sync conflict', 'iCloud upload failed', 'ubiquitous item error', 'data not appearing on other devices', 'CKError', 'quota exceeded' - systematic iCloud sync diagnostics for both CloudKit and iCloud Drive
adding-inbound-webhooks
by PostHog
Use when adding a webhook endpoint for a third party that sends to PostHog, adding an inbound webhook consumer for a provider that already has an endpoint, or migrating a hand-rolled hmac verifier that the inbound-webhooks-go-through-ingress semgrep rule flags. Covers the two jobs separately: a consumer in products/<product>/backend/webhook_consumers.py, and a provider incarnation under posthog/ingress/<provider>/ wired with build_webhook_view(). Carries the rules that are easy to get wrong: a consumer name is a dedup cache key, event types must be declared by the provider app or the registry raises, and the module stays cheap to import. Trigger terms: add a webhook, webhook consumer, inbound webhook, hand-rolled hmac, inbound-webhooks-go-through-ingress.
axiom-background-processing
by CharlesWiltgen
Use when implementing BGTaskScheduler, debugging background tasks that never run, understanding why tasks terminate early, or testing background execution - systematic task lifecycle management with proper registration, expiration handling, and Swift 6 cancellation patterns
axiom-camera-capture-diag
by CharlesWiltgen
camera freezes, preview rotated wrong, capture slow, session interrupted, black preview, front camera mirrored, camera not starting, AVCaptureSession errors, startRunning blocks, phone call interrupts camera
axiom-core-location
by CharlesWiltgen
Use for Core Location implementation patterns - authorization strategy, monitoring strategy, accuracy selection, background location
axiom-extensions-widgets-ref
by CharlesWiltgen
Use when implementing widgets, Live Activities, Control Center controls, or app extensions - comprehensive API reference for WidgetKit, ActivityKit, App Groups, and extension lifecycle for iOS 14+
axiom-energy-diag
by CharlesWiltgen
Symptom-based energy troubleshooting - decision trees for 'app at top of battery settings', 'phone gets hot', 'background drain', 'high cellular usage', with time-cost analysis for each diagnosis path
axiom-energy-ref
by CharlesWiltgen
Complete energy optimization API reference - Power Profiler workflows, timer/network/location/background APIs, iOS 26 BGContinuedProcessingTask, MetricKit monitoring, with all WWDC code examples
axiom-app-store-submission
by CharlesWiltgen
Use when preparing ANY app for App Store submission - enforces pre-flight checklist, rejection prevention, privacy compliance, and metadata completeness to prevent common App Store rejections
axiom-getting-started
by CharlesWiltgen
Use when first installing Axiom, unsure which skill to use, want an overview of available skills, or need help finding the right skill for your situation — interactive onboarding that recommends skills based on your project and current focus
axiom-display-performance
by CharlesWiltgen
Use when app runs at unexpected frame rate, stuck at 60fps on ProMotion, frame pacing issues, or configuring render loops. Covers MTKView, CADisplayLink, CAMetalDisplayLink, frame pacing, hitches, system caps.
axiom-asc-mcp
by CharlesWiltgen
Use when automating App Store Connect via MCP — submit builds, manage TestFlight, respond to reviews, triage feedback programmatically
lean4
by cameronfreer
"Use when editing .lean files, seeing type mismatch/sorry/failed to synthesize instance/axiom warnings, lake build errors, or searching mathlib for theorem proofs."
Skill Evolution Manager
by KKKKhazix
专门用于在对话结束时，根据用户反馈和对话内容总结优化并迭代现有 Skills 的核心工具。它通过吸取对话中的“精华”（如成功的解决方案、失败的教训、特定的代码规范）来持续演进 Skills 库。
editing-agents-md
by PostHog
Decide whether a rule belongs in an AGENTS.md / CLAUDE.md file, and write it so it holds. Use before adding, editing, or removing any instruction in a root or nested AGENTS.md, when a convention keeps getting broken and someone proposes documenting it, when reviewing a diff that touches one, or when a file has grown and needs a trim. Carries the enforcement-tag convention ([lint: <id>] / [review]), the six configuration smells to check against, and the size budget. Trigger terms: AGENTS.md, CLAUDE.md, agent instructions, context file, add a rule, document this convention, the file is too long.
create-skill
by xstongxue
Guides users through creating effective Agent Skills for Cursor. Use when the user wants to create, write, or author a new skill, or asks about skill structure, best practices, or SKILL.md format.
