Peitho: Prose That Holds a Reader

Most writing skills tell your agent to "write clearly" and hope. This one carries the actual rules: a banned-word catalog, a hard em-dash ceiling with exactly three exceptions, a coherence pass that runs on the finished text, and a 0 to 5 scorecard your draft has to clear before it ships.

The part that matters most is the fork at the top. If you hand it a draft you wrote, it switches into edit mode and is forbidden from restructuring, reordering, or replacing your voice. It returns your draft plus an itemized list of what it changed, so you can reject any single edit. If you hand it nothing, it composes from scratch.

Every claim in the skill is tagged by evidence tier, and the ones that do not replicate are marked as such rather than quietly dropped.

Ships with ten reference files: the machine-prose tells, the coherence maintainer, the fiction delta, the honest-persuasion rail, historical openings reverse-engineered, five pieces of standard hook advice the evidence kills, and the scorecard rubric.

Where this came from

Deliberon is a Windows desktop app that runs a council of AI agents on a hard decision and hands back a Decision Record: dissent preserved, every claim marked as proved, asserted, or estimated.

Peitho is the prose method behind its writing, published in full because a persuasion technique you cannot inspect is one you cannot defend against.

Pay once, it's yours, no subscription. Thirty days of the full council with no account and no card. Runs on your machine with your own model keys.
