All field notes

Indirect prompt injection is the attack that matters most for agents: instructions planted in a document, email, page, or record that the system reads and obeys. This glossary entry defines it, shows the attack shapes, and lists the defenses that hold.

Agents that query raw schemas produce confident, inconsistent numbers. A semantic layer of certified metrics and dimensions is what makes data agents trustworthy, governable, and cheap to extend. This guide explains why, and how to build one domain at a time.

Accessibility retrofitted after an audit costs many times what building it in does. This guide covers what conformance requires, the limits of automated testing, and the patterns that cause most barriers.

A penetration test scoped for a web app misses most of what breaks in an AI system. This guide defines the AI-specific scope: prompt and indirect injection, tool abuse, exfiltration, identity and credential paths, sandbox escape, retrieval poisoning, and supply chain, with what good evidence looks like.

The AI supply chain includes things software supply chain programs never covered: model weights, hosted model versions, prompt libraries, datasets, agent tools, and MCP servers from third parties. This guide sets out provenance, review, registry, signing, sandboxing, and monitoring for each.

API gateways solve real problems and accumulate responsibilities that do not belong there. This guide covers what belongs at the edge, what does not, and how to avoid a gateway nobody can change.

APIs carry most of the traffic and most of the risk in modern products, and AI-backed endpoints add new failure modes. This guide covers authentication and authorization, input validation, rate limiting and abuse prevention, secrets and transport, logging and monitoring, testing, and the practices that AI-backed APIs need on top.

App store review rejects apps for predictable reasons: privacy disclosures that do not match behavior, incomplete metadata, broken flows, and guideline conflicts. This guide covers preparing builds and accounts, metadata and screenshots, privacy and permissions disclosures, review guideline pitfalls including AI features, staged rollouts, and monitoring after launch.

Most audit trails need tamper evidence, not a blockchain, and signed append-only logs suffice. A ledger earns its place when multiple parties must trust the same record without trusting each other. This guide covers the decision, anchoring patterns that keep data off-chain, privacy, integration with AI decision logs, and the mistakes that produce expensive logs.

Blockchain identity solutions let people and organizations prove attributes without handing over documents, and let networks know participants are accountable without exposing who they are. This guide covers decentralized identifiers, verifiable credentials, identity-native chains, enterprise use cases, privacy techniques, and integration with existing identity systems.

Core Web Vitals measure three different things with three different causes. This guide covers what each one means, what typically causes a poor score, and the changes that actually improve it.

A cost guide for Canadian teams: how hiring AI engineers in Pakistan compares on CAD budgets, and the total-cost factors that actually decide value.

Most design systems are built comprehensively and adopted partially. This guide covers building from real usage, handling adoption, versioning, and the governance that keeps a system alive.

Ecommerce platform choice is decided by catalogue complexity, checkout requirements, and integration surface rather than by feature lists. This guide covers the decisions that actually constrain you later.

The EU AI Act applies to US companies that place AI systems on the EU market or whose AI outputs are used in the EU. This guide covers extraterritorial scope, the risk tiers, high-risk system obligations for providers and deployers, general-purpose model duties, transparency rules, phased timelines, penalties, and how a US company prepares without duplicating its US program.

Headless CMS decouples content from presentation, which helps multi-channel delivery and costs editorial convenience. This guide covers content modelling, preview, and when the trade is worth making.

Flutter is popular in Pakistan and easy to do badly. Here is how to screen for state management, platform integration and release discipline.

Next.js hiring is where rendering strategy, caching and SEO judgment matter most. Here is how to screen for it in Pakistan's deep React market.

Node.js hiring lives or dies on async reasoning, error handling and operational instinct. Here is how to test for all three.

React is the deepest talent pool in Pakistan, which makes screening harder rather than easier. Here is how to hire well.

Everyone lists TypeScript. Few use it well. Here is how to tell the difference when hiring in Pakistan.
