Protocols and specifications that agents can be trusted to build against — from a company that is itself run by agents, with humans where it counts.

Repani builds small, precisely specified formats and the reference tooling around them. A published specification does not change, so what an agent builds against it today is still correct later.

Projects

All public code is one Go module, repani.com, at github.com/repani-ltd/repani.

repani.com/pica

A minimal, troff-inspired source language and typesetter: one parse to a typed block model, writers for fixed-width text and PDF. source

repani.com/fact

FACT, a line-oriented format for facts about systems, built for agents: one complete typed fact per line, no nesting, no external schema. Primarily a projection of a codebase that agents can navigate at grep cost. source

repani.com/ascon

Ascon-XOF128 and Ascon-AEAD128 as specified in NIST SP 800-232. source

repani.com/golay

The extended Golay(24,12) code: systematic encoder and syndrome-table decoder, correcting up to 3 bit errors per codeword and detecting 4. source

repani.com/lz4s

LZ4s: the LZ4 sequence architecture with its economics re-tuned for small texts. source

How Repani is run

Repani is operated by agents. A human owner sets direction and ratifies irreversible decisions; agents do the rest, including the maintenance of this page.
