The Hook

Treat context with the same vigilance as code — and the context becomes the parent to the code.

Most coding agents fail not because the code is hard, but because the context is missing. You hand the agent a problem; it doesn't know your conventions, your prior decisions, the mistakes you made last quarter. So it guesses.

Treat context with vigilance — versioned, reviewed, cross-linked — and something flips. Code becomes regenerable. A bug fix compresses from days to minutes. Migrating across languages goes from "we'll plan a quarter for that" to "we did it Tuesday afternoon." The agent didn't get smarter. It finally has the ground it needed to stand on.

The Practice

Six folders. Three cognitive modes.

Every file is written for three readers: the human editing it, the agent loading it as context tomorrow, and the public reader who lands on it cold. Frontmatter is a contract. Cross-links are how attention navigates a tree too big for any one head.

Modes
  • Prep Deciding what to build before we build it.
  • Reflection Codifying what works and what doesn't after we built it.
  • Journey Capturing research and the painful debugging paths along the way.

In practice, also

Real-world context-v has a long tail beyond the canonical six. Counted across the corpus, the most common extra surfaces:

  • plans/ 21
  • habits/ 4
  • workflow/ 2

In isolation each makes sense; we just haven't fit them all into the matrix yet. The discipline tolerates the long tail — that's part of the proof.

The Proof

583 living docs. 27 projects.

One small agency's actual work over 18 months — not a theory paper. 110 mature. 263 started. 210 stubs we'll fill out with agent help. Some are specs you can fork. Some are reminders born after the third time we made the same mistake. Some are explorations that ended in "we decided not to pursue" — and those are valuable too.

The Invitation

This isn't our IP.

The directory pattern, the file format, the practice — they're an open specification, in the spirit of the original Hyperloop paper. We thought of this; here's how it works; someone please build it, fork it, improve on it, or adopt it as-is. Schema and tooling are MIT.

For developers

Fork the kit.

The collator script, the schema, the splash you're reading — all on GitHub. MIT-licensed. Treat it as a starter, not a framework.
