For people who know what they want to build and need help shipping it.

abcd helps a product thinker realise an intent as a high-fidelity prototype or demonstrator — carrying the why from idea to shipped reality. State what should exist, why, for whom, and what good looks like, as a press-release intent (/abcd:intent "<text>"); abcd holds that why through planning (/abcd:intent plan), the readiness gate (/abcd:intent ready) and delivery, and when the work lands it is audited against the intent's own acceptance criteria (/abcd:intent audit), with the verdict recorded on the intent, so what was promised and what was delivered are read side by side. The lifeboat is a key capability of the same product: point /abcd:disembark pack <source-repo> <dest> at any repository — one that has grown unwieldy, or one that died years ago and that abcd never managed — and abcd reads it without writing a single byte back, packing its hard-won knowledge — decisions, principles, pitfalls, the graveyard of what failed, the spine of what was built and why — into a portable lifeboat artefact at <dest>, alongside a coverage report that names what it could not ground and the questions a human must answer. /abcd:disembark probe <source-repo> renders that coverage verdict on its own, and /abcd:embark from <path> unpacks a lifeboat into a clean foundation with the same wisdom but none of the cruft. A small command surface rounds out the workflow: install (/abcd:ahoy install) and public release (/abcd:launch ship); /abcd:capture keeps discovered issues structured as the project evolves; and /abcd:library keeps the documents you consult and curates a queryable knowledge substrate from those same sources. Bare invocation of any command shows status + suggested next actions; state-mutating actions require an explicit sub-verb (the universal abcd convention).

"I know what I want built and I can tell in a minute whether a prototype got it right. What I could never do was hold that line through the engineering. abcd takes the why as I wrote it, builds against it, and shows me what was promised next to what was delivered," said Iris, a product thinker.

"I'd hit the wall on a side project three times this year — every rebuild from scratch lost the lessons I'd already learned the hard way. abcd is the first tool that treats those lessons as the output worth saving, not just the code," said Maya, an AI/agent researcher.
