## Pages

- [Memex: the spec-driven development system for AI coding agents](https://www.memex.ai/): Memex is the spec-driven development system for AI coding agents: one living spec your agents build from and are verified against, so decisions, standards, and acceptance criteria are proven in CI.
- [Pricing](https://www.memex.ai/pricing): Memex pricing — plans for individual builders and teams shipping software with AI coding agents.
- [Documentation](https://www.memex.ai/docs): How Memex works: Specs, decisions, standards, tasks, and the MCP server that connects your AI coding agents to the workspace.
- [The Name](https://www.memex.ai/story): Why we called it Memex: the origin of the name and the idea behind the spec-driven development system.
- [Community](https://www.memex.ai/community): Join the Memex community: the open, source-available project for AI-native software teams. Contribute on GitHub, join the Discord, and help shape spec-driven development.
- [Writing](https://www.memex.ai/writing): Essays on AI-native software development, agentic coding, and how engineering changes when agents do the typing.
- [Extreme AI Programming](https://www.memex.ai/writing/extreme-ai-programming): A series on extreme AI programming — what software engineering becomes when AI agents do the work and humans direct it.
- [The Extreme AI Programming Manifesto](https://www.memex.ai/writing/extreme-ai-programming/01-manifesto): Part 1 of Extreme AI Programming: a manifesto for how we build software now that agents do the typing.
- [The Second Punch-Card Era](https://www.memex.ai/writing/extreme-ai-programming/02-second-punch-card-era): Part 2 of Extreme AI Programming: why prompting an agent feels like the punch-card era — and what comes next.
- [The Bottleneck Moved](https://www.memex.ai/writing/extreme-ai-programming/03-bottleneck-moved): Part 3 of Extreme AI Programming: the bottleneck in software is no longer typing — it is deciding and verifying.
- [The Prompt Is the Work](https://www.memex.ai/writing/extreme-ai-programming/04-prompt-is-the-work): Part 4 of Extreme AI Programming: the prompt, the spec, and the decision record are the real engineering artifacts now.
- [Which Ceremonies Survive](https://www.memex.ai/writing/extreme-ai-programming/05-ceremonies-survive): Part 5 of Extreme AI Programming: which software-engineering rituals survive the move to agentic coding, and which die.
- [Beyond Vibe Coding](https://www.memex.ai/writing/extreme-ai-programming/06-vibe-coding): Part 6 of Extreme AI Programming: why "vibe coding" breaks at scale and what disciplined agentic development looks like.
- [Testing Without Drudgery](https://www.memex.ai/writing/extreme-ai-programming/07-testing-without-drudgery): Part 7 of Extreme AI Programming: how verification and testing work when agents write the code and the tests.
- [The Spec Is Not a Document](https://www.memex.ai/writing/extreme-ai-programming/08-spec-driven-development): Part 8 of Extreme AI Programming: why an AI-native spec is a database of six primitives, not a prose document, and why that shape is what makes the pace sustainable.
- [Kent Beck Recalibrated](https://www.memex.ai/writing/extreme-ai-programming/09-beck-changed-his-mind): Part 9 of Extreme AI Programming: what happened when Kent Beck looked at AI coding and concluded ninety per cent of his skills had just been repriced to nothing.
- [Where the Craft Went](https://www.memex.ai/writing/extreme-ai-programming/10-where-the-craft-went): Part 10 of Extreme AI Programming: the craft did not die when agents took the typing. It moved upstream, to the architecture, the design, the decisions, and the one thing the machine cannot do.
- [The AI Coding Fluency Model](https://www.memex.ai/writing/extreme-ai-programming/11-ai-fluency-model): Part 11 of Extreme AI Programming: every team says it is AI-first, and no two mean the same thing. Five levels of fluency, from no AI at all to the factory that runs itself.
