Agentic Pair
WorkflowHuman + AI agent actively pairing on code. "Agent driver, me navigator" — Cursor Composer's natural mode.
AGENTS.md
WorkflowInstruction file an AI agent auto-reads on project entry. Coding standards, common commands, architecture notes. Same intent as CLAUDE.md, different name.
AI / LLM.
View all 114Adapter
AI / LLMSmall learnable modules slotted into a pretrained model. New adapter per task, base model frozen.
Agentic RAG
AI / LLMRAG embedded in an agent: the model rewrites queries, runs multiple searches, synthesizes results.
Alignment
AI / LLMThe discipline of aligning a model's behavior with human values and intent. RLHF, Constitutional AI, DPO are its techniques.
ARC-AGI
AI / LLMFrançois Chollet's abstract visual reasoning test. Marketed as the "closest to AGI" benchmark; not yet solved.
Attention
AI / LLMThe mechanism that computes how much weight to give other tokens in the input when producing the next one. The heart of the Transformer.
Autoregressive
AI / LLMPredicting the next token from the prior ones. The default behavior of LLMs.
Security.
View all 1132FA
SecurityTwo-Factor Authentication. The two-factor case of MFA; usually password + TOTP/SMS.
ABAC
SecurityAttribute-Based Access Control. "User in this dept and file at this sensitivity" style policy. More flexible than RBAC, higher complexity.
Access Token
SecurityShort-lived (usually 1h) bearer token for API access. Can be a JWT or opaque.
ACL
SecurityAccess Control List. Per-resource list of user/role permissions. Linux file perms; AWS S3 bucket policies.
Adversarial Attack
SecurityAdding small but purposeful perturbations to input to fool a model. Classic for image classifiers; adapted to LLMs.
Audit Log
SecurityRecords of who did what, when. Required for SOC2 compliance + incident investigation.
Growth.
View all 112301 Redirect

AARRR Funnel
GrowthPirate Metrics: Acquisition, Activation, Retention, Referral, Revenue. Dave McClure's framework that defined growth.
Abandoned Cart
GrowthUser adding to cart but not completing checkout. E-commerce's biggest leak; recovery emails are standard.
AEO
GrowthAnswer Engine Optimization. Structuring content to be cited in Google AI Overview, Perplexity, You.com answers.
Affiliate Program
GrowthSystem where third parties promote your product for commission. PartnerStack, Rewardful for integration.
AI Overview
GrowthGoogle's LLM-generated summary above SERP. Erodes classic blue-link clicks; the "zero-click" era.
Culture.
View all 10610x Engineer
CultureThe mythical dev claimed to deliver 10x output in the same time. Got more real in the AI era; debate continues.
AI Booster
CultureGroup focused on AI benefits, minimizing risks. The broad umbrella of e/acc.
AI Slop
CultureThe flood of low-quality AI-generated content drowning the internet — SEO blogs, fake reviews, automation channels.
AI-Pilled
CultureFrom "red pill" jargon: a dev who's switched to coding with AI. No going back to the old way.
Analysis Paralysis
CultureFreezing up because too many options to choose from. Classic trap in tech stack decisions.
Anemic Domain Model
CultureA model that's just getters/setters, with behavior dumped into services. Martin Fowler's famous anti-pattern.
Agentic.
View all 99Action Step
AgenticThe moment an agent fires a concrete tool call. The transition from reasoning to action.
Agent Fork
AgenticBranching from an existing trajectory to try a new path. Ideal for "what-if" exploration.
Agent Graph
AgenticLangGraph's state-machine model where nodes = agents/tools and edges = handoffs. Makes complex flows visualizable.
Agent Loop
AgenticAn agent's think → call tool → observe → repeat loop until the goal is met. Most modern AI apps are this loop.
Agent Memory
AgenticSystem for an agent to store and recall information within or across sessions. Short, long, episodic, semantic flavors.
Agent Resume
AgenticContinuing an old session/trajectory exactly where it stopped. `codex resume`, `claude --resume`.
Core.
Agentic Coding
CoreA development style where AI operates as an autonomous agent — reading files, running commands, seeing errors, iterating. Beyond inline autocomplete.
Agentic Engineering
CoreKarpathy's mature successor to vibe coding. Agents handle bounded sub-tasks; the developer keeps architectural ownership and reviews critical outputs. Disciplined vibe coding.
Autonomous Coding
CoreA mode where AI works on its own with minimal human intervention. You set the goal and constraints; the agent runs, returns. Takes guts and good evals.
Vibe Coding
CoreBuilding software by chatting with AI in flow, without reading every line — relying on intuition. Coined by Andrej Karpathy in Feb 2025: "Give in to the vibes, forget the code exists." Collins Dictionary Word of the Year 2025.
