DOMPurify XSS sanitization for HTML content in agent outputs. Strip script tags and event handlers, allowlist-based tag/attribute filtering, sanitize LLM-generated HTML before rendering, and defend against DOM clobbering. Sources: cure53/DOMPurify.

Program LM pipelines with DSPy — define Signatures (input/output fields), build Modules (ChainOfThought, ReAct, Predict), compose them into Programs, then optimize with Teleprompters (BootstrapFewShot, MIPRO, COPRO) to auto-improve prompts from examples.

Durable background job and task queue patterns for AI agent systems. BullMQ Redis-backed queues with concurrency + rate limiting, Inngest event-driven durable functions, Trigger.dev background tasks, dead-letter queue patterns, and job failure diagnostics. Sources: taskforcesh/bullmq, inngest/inngest, triggerdotdev/trigger.dev, OptimalBits/bull, agenda/agenda.

Task-local harness system — declare owns/consumes/produces/pass-fail before dispatch, extract to shared skill when repeated. Use instead of inline ad-hoc steps for any task spanning >1 session or >3 files. Triggers on: 'dynamic workflow', 'task harness', 'harness per task', 'custom harness', 'adaptive workflow', 'task-local harness', 'owns consumes produces', 'harness template', 'dynamic mode', 'workflow harness'.

eBPF-based runtime behavioral monitoring for detecting sandbox escapes and privilege escalation. Tracee event signatures, file access monitoring, network connection alerts, and process execution tracing. Sources: aquasecurity/tracee.

Monitor and intercept Linux kernel syscalls from agent processes using eBPF (Extended Berkeley Packet Filter). Real-time syscall filtering, PID-based policy enforcement, cgroups v2 throttling, and seccomp profile generation.

Navigation guide cho ECC — onboarding, tìm skills/agents/commands phù hợp, setup, troubleshooting. Dùng khi cần hỏi 'làm X với ECC như thế nào?'

Elliptic curve cryptography for agent key pairs and command signing. EC key generation (secp256k1/p256), ECDSA sign/verify, ECDH shared secret, DER/PEM encoding, and hardware-safe key storage patterns. Sources: indutny/elliptic.

Audit cost overrun cho ECC Tools GitHub App — investigate runaway PR creation, quota bypass, premium-model leakage, duplicate jobs, billing spikes.

Everything Claude Code (ECC) — agent harness configuration layer for Claude Code and other AI coding IDEs. Augments agents with skills, hooks, persistent memory, model routing, and quality gates without modifying the underlying model.

Enterprise-grade component architecture patterns from 20 production design systems. Component naming, data-dense layouts, headless patterns, accessible forms, and dev-tool UI conventions. Sources: IBM Carbon, Adobe React Spectrum, Palantir Blueprint, GitHub Primer, Microsoft Fluent, Salesforce, Workday Canvas, Twilio Paste, Pinterest Gestalt, and 11 others.

Envoy L7 proxy filter chains, xDS dynamic configuration, rate limiting, request mirroring, and Lua/WASM filter patterns for sidecar-level traffic control in agent networks. Sources: envoyproxy/envoy (Apache-2.0).

Systematically remove malware, backdoors, and attacker persistence mechanisms

Production error handling — typed errors, Result type, error boundaries, structured logging, retry strategies

Design structured application error handling — error type hierarchy, error codes, propagation strategy (throw vs return), user-facing vs internal messages, HTTP error response format, async error safety, and React error boundaries. Use when asked to "improve error handling", "structured errors", "error codes", "error types", "don't swallow errors", "unhandled promise rejection", "error boundary", "error response format", "what to show users when something fails", or before shipping any featur...

ESLint custom rule architecture. AST visitor rules with auto-fix, rule metadata, nested rule hierarchies, RuleTester harness, and monorepo-wide static analysis configuration. Sources: eslint/eslint (MIT).

ESTree standard AST node types for JavaScript analysis. Node structure reference, custom AST walkers, node type guards, and building AST-based tools from the official ECMAScript AST specification. Sources: estree/estree (MIT).

etcd distributed key-value store for centralized agent config and distributed locking. Watch API for live config reload, lease-based TTL keys, transactions, and distributed mutex patterns. Sources: etcd-io/etcd (Apache-2.0).

Eval-driven agent development — 3-layer evaluation (static benchmarks, custom offline, online production). Evaluator-optimizer tight loop. Evals in CI, score-gated PRs. SWE-bench/GAIA/BFCL V4 for cross-model comparison. Trajectory-based and LLM-as-judge evals. Sources: rohitg00/ai-engineering-from-scratch (Apache-2.0).

Design event-driven systems — event sourcing, CQRS, saga pattern for distributed transactions, message queue patterns, and event schema design. Use when asked about "event sourcing", "CQRS", "saga", "distributed transaction", "message queue", "Kafka", "publish/subscribe", "event-driven", or "how to coordinate across services without direct calls". Do NOT use for: real-time WebSocket UI patterns — that is a frontend concern.
