AI-assisted engineering, with evidence

Build features with agents. Keep engineering in control.

PromptGrinder turns AI coding prompts into deterministic, reviewable delivery trains: smaller slices, explicit ownership, durable Git checkpoints, safe recovery, and isolated parallel worktrees.

Start with the repository

Install PromptGrinder, then let it inspect the project before defining work:

promptgrinder discover
promptgrinder roles enhance
promptgrinder roles review latest

The resulting project and role evidence gives workers useful context while keeping their ownership boundaries explicit.

Support at a glance

Surface Current status
macOS Apple silicon and Intel Supported release-candidate surface
Headless, Terminal.app, and iTerm2 Supported execution surfaces
Codex CLI Supported for run, run-folder, and named workers
Antigravity Supported for named workers through its agy adapter
Models Selected from the signed-in runtime’s live catalog and bounded by repository policy
MCP servers Configured and owned by the selected engine; PromptGrinder-native management is future work
Linux, Windows, other terminals, and other engines Not qualified or supported yet

Codex CLI 0.150.x is the known-qualified band. Other versions can run as provisional when they pass PromptGrinder’s non-mutating adapter capability probe; a missing required capability blocks the train before worker creation.
