The mythical dev claimed to deliver 10x output in the same time. Got more real in the AI era; debate continues.

Two-Factor Authentication. The two-factor case of MFA; usually password + TOTP/SMS.

Permanent redirect HTTP status code. Carries 95%+ of backlink equity; the staple of site migrations.

Asking "why?" five times in a row to dig to the root cause. From Toyota Production System.

Splitting traffic across two versions and comparing metrics. Classic growth technique; applies to AI prompts too.

Pirate Metrics: Acquisition, Activation, Retention, Referral, Revenue. Dave McClure's framework that defined growth.

Attribute-Based Access Control. "User in this dept and file at this sensitivity" style policy. More flexible than RBAC, higher complexity.

User adding to cart but not completing checkout. E-commerce's biggest leak; recovery emails are standard.

Short-lived (usually 1h) bearer token for API access. Can be a JWT or opaque.

3D, fluid, premium-feel React component library. Lit up indie SaaS landing pages.

Atomicity, Consistency, Isolation, Durability. The transactional DB guarantee contract.

Access Control List. Per-resource list of user/role permissions. Linux file perms; AWS S3 bucket policies.

The moment an agent fires a concrete tool call. The transition from reasoning to action.

The moment a new user first experiences real value. Slack's "first 2000 messages" is the classic example.

Small learnable modules slotted into a pretrained model. New adapter per task, base model frozen.

Architecture Decision Record. Capture the context, alternatives, and outcome of an architectural decision. Future you thanks past you.

Adding small but purposeful perturbations to input to fool a model. Classic for image classifiers; adapted to LLMs.

Answer Engine Optimization. Structuring content to be cited in Google AI Overview, Perplexity, You.com answers.

System where third parties promote your product for commission. PartnerStack, Rewardful for integration.

Branching from an existing trajectory to try a new path. Ideal for "what-if" exploration.

LangGraph's state-machine model where nodes = agents/tools and edges = handoffs. Makes complex flows visualizable.

An agent's think → call tool → observe → repeat loop until the goal is met. Most modern AI apps are this loop.

System for an agent to store and recall information within or across sessions. Short, long, episodic, semantic flavors.

Continuing an old session/trajectory exactly where it stopped. `codex resume`, `claude --resume`.

Front-layer that routes incoming prompts to the most fitting specialist agent. Optimizes cost and quality.

A library for building your own AI agent programmatically. Anthropic Agent SDK, OpenAI Assistants, etc.

A modular capability bundle handed to an agent. Markdown instructions + tools + examples. Claude Code Skills productizes this.

A loosely coupled, parallel-running group of many small agents. Ant-colony logic; OpenAI Swarm exemplifies this idea.

Full log of an agent run including every LLM call, tool, observation. LangSmith, Braintrust, Helicone surface it.

Singular form of AGENTS.md. Some projects prefer this name; same content.

When a model goes beyond replying — planning, calling tools, and acting toward a goal. Opposite of a passive chatbot.

A development style where AI operates as an autonomous agent — reading files, running commands, seeing errors, iterating. Beyond inline autocomplete.

Karpathy's mature successor to vibe coding. Agents handle bounded sub-tasks; the developer keeps architectural ownership and reviews critical outputs. Disciplined vibe coding.

Human + AI agent actively pairing on code. "Agent driver, me navigator" — Cursor Composer's natural mode.

RAG embedded in an agent: the model rewrites queries, runs multiple searches, synthesizes results.

Agent doing query → search → evaluate → new query in a loop instead of one search. The basis of modern web research.

A workflow chaining planning + tools + verification steps instead of a single LLM call.

OpenAI's 2026 agent toolkit. Studio, ChatKit, Connectors → building agents inches toward no-code.

Instruction file an AI agent auto-reads on project entry. Coding standards, common commands, architecture notes. Same intent as CLAUDE.md, different name.

Phidata's lightweight Python agent framework. Stands out on performance; minimal agent + tool + memory API.

The moment the user goes "ohhh, this is why I'd use this." The heart of activation.

Group focused on AI benefits, minimizing risks. The broad umbrella of e/acc.

Google's LLM-generated summary above SERP. Erodes classic blue-link clicks; the "zero-click" era.

The flood of low-quality AI-generated content drowning the internet — SEO blogs, fake reviews, automation channels.

A product/company designed assuming AI exists from day one — not bolted on later. Not "Notion + AI" but "AI-first Notion."

From "red pill" jargon: a dev who's switched to coding with AI. No going back to the old way.

Paul Gauthier's CLI coding agent. Git-native, multi-file edit, repo-map. The OG of open-source vibe coding.

AI for observability + incident management. Anomaly detection, root cause suggestion, alert correlation; Datadog, New Relic's 2024+ playbook.

Azure Kubernetes Service. Azure's managed K8s. EKS/GKE counterpart; tight Microsoft ecosystem integration.

Application Load Balancer. AWS's L7 HTTP/HTTPS load balancer. Path/host routing, WebSocket support.

Hosted search infrastructure. De facto for docs sites via DocSearch; sub-50ms search.

The discipline of aligning a model's behavior with human values and intent. RLHF, Constitutional AI, DPO are its techniques.

"Best alternatives to X" page. You catch the rival's churning customers. Indie SaaS classic.

Sourcegraph's agentic CLI and VS Code extension. Codebase-aware context + team-shared threads.

Accelerated Mobile Pages. Google's 2015 fast-mobile HTML push; died in 2024, no one mourned.

Have the model generate similar example problems and solve them before tackling the target. "First write 3 similar problems, solve them, then attack the real one."

Freezing up because too many options to choose from. Classic trap in tech stack decisions.

Putting the most expensive plan at the top to make others feel cheap. Behavioral psychology + pricing.

A model that's just getters/setters, with behavior dumped into services. Martin Fowler's famous anti-pattern.

Annual prepayment + discount. Eases cash flow; cuts churn risk.
