- performance-optimizationgamedev-skills/awesome-gamedev-agent-skillsFind and fix game performance problems methodically — measure with the engine profiler first, reason about the frame-time budget, locate the CPU-vs-GPU bottleneck, then apply the right fix: object pooling, draw-call batching, fewer allocations/GC spikes, and asset budgets. Engine- neutral method that pairs with each engine's profiler. Use when the user mentions performance, optimize, low/dropping FPS, frame drops, stutter, lag, profiler, frame budget, draw calls, batching, garbage collection/GC spikes, object pooling, or "the game runs slow".OtherNo warnings★ 6.2K↓ —
- certisyn-independent-verificationNewinternet-court/internet-court-skillIndependent, third-party verification of what a counterparty claims about itself, established BEFORE an agent commits funds, signs, delegates authority, or admits that counterparty to a deal. Declared coverage today is verification by physical law - vehicle telemetry and orbital node claims - where a finding is arithmetic that can be re-derived rather than an opinion that must be weighed. Use for any reliance on a counterparty assertion, when drafting the verification clause of an agreement, and when assembling or assessing a dispute filing. Returns one of four outcomes, always names what it could not determine, and states the conditions under which its own evidence should be ruled out.LegalNo warnings★ 7K↓ —

- hunt-jwt-cryptoelementalsouls/Claude-BugHunterHunt JWT cryptographic failures — alg:none signature-stripping and RS256→HS256 key-confusion that let an attacker forge a token for any identity (e.g. an admin) without knowing a secret. Use when the app authenticates with a JSON Web Token (an `eyJ...` Bearer token in the Authorization header, a cookie, or a login response). This skill OWNS JWT signature/crypto forgery (alg:none, key confusion, kid/jku header injection); hunt-ato covers JWT as one ATO path, hunt-auth-bypass covers SSO/SAML token trust, hunt-api-misconfig covers non-crypto JWT handling. Critical when a forged token grants access to another user's data or an admin-only endpoint.FinanceNo warnings★ 5.4K↓ —
- template-validationdotnet/skillsValidates custom dotnet new templates for correctness before publishing.

Triggers on: input, bindKey, isKeyPressed, KEY, registerPointerEvent, releasePointerEvent, pointerdown, pointerup, pointermove, POINTERMOVE, gamepad, bindGamepad, triggerKeyEvent, virtual gamepad, touch controls, joystick, gamepad-plugin, KEYDOWN, KEYUP, press any key, splash screen, click, touch, drag, hit test, event propagation, stop propagating, overlapping, which object gets the click.TestingNo warnings★ 6.4K↓ —
- plugin-bundle-sizegrafana/skillsOptimise Grafana app plugin bundle size using React.lazy, Suspense, and webpack code splitting.

Triggers on phrases like "optimise plugin bundle size", "module.js is too large", "plugin is slow to load", "code split the plugin", "reduce initial JS payload", or "help me with Suspense in my plugin".OfficialEngineeringNo warnings★ 300↓ —
- godot-physicsgamedev-skills/awesome-gamedev-agent-skillsUse Godot 4.7 physics bodies and detection in 2D and 3D: RigidBody, StaticBody, Area, and CharacterBody; collision layers vs masks; contact/overlap signals; and raycasts (RayCast nodes and direct space-state queries). Use when configuring collision layers/masks, detecting overlaps with Area2D/Area3D, applying forces to a RigidBody, or casting rays in a Godot project (.tscn with physics bodies), including 3D projects running Jolt Physics, the default 3D engine for projects created in 4.6+.ScienceNo warnings★ 6.2K↓ —
- cloud-iam-deepelementalsouls/Claude-BugHunterCloud IAM red-team attack chain across AWS, Azure, GCP — focused on EXTERNAL exploitation paths and post-credential-discovery privilege analysis. Covers IAM enumeration (aws iam, az role, gcloud iam), STS/AssumeRole chaining, Azure Managed Identity abuse (via SSRF/leak), GCP service account JSON abuse, IMDSv1/v2 attacks via SSRF, K8s ServiceAccount token privilege analysis once held (token discovery / cluster exposure is owned by hunt-k8s), role-trust-policy confused-deputy, cross-account assume-role enumeration, IAM privilege escalation patterns (24+ AWS, 8+ Azure, 6+ GCP), and AWS Cognito Identity Pool unauthenticated-role attack chain (GetId → GetCredentialsForIdentity → IAM role abuse). Built for the case where recon yields a credential (key, JSON, token) and you need to know what it grants and how to escalate. Use when an AWS key / Azure secret / GCP service account JSON / K8s SA token surfaces from a code repo, JS bundle, APK, breach corpus, or SSRF chain.DevOpsNo warnings★ 5.4K↓ —

From the author
Use this skill when a feature works on one machine and not another, when choosing or pinning a renderer, or when writing code that must degrade gracefully. Covers the WebGPU to WebGL 2 to Canvas fallback ladder, what each backend supports, capability detection, and the subsystems that warn once and then stop working on Canvas. Triggers on: video.AUTO, video.WEBGPU, video.WEBGL, video.CANVAS, renderer.type, supportsDepthBuffer, shaderLanguage, WebGPU, WebGL2, Canvas fallback, context loss, backend, works on my machine.
