Hook builder

Build a hook configuration

Pick up to 8 rules from the registry, set their parameters, choose a graduation mode and authority mode — then validate the composed launch spec with the launcher's own deterministic validator, running entirely in your browser.

Configuration validation — checks the spec against the launcher's rules. Not a guarantee of on-chain execution.

The validator is the launcher's validate-config.mjs bundled for the browser (self-hosted, no CDN) — the same code, error codes and messages as the CLI. Rule 14 (Decay Tax) fails on the standard DBC path and rule 18 (Buy Cooldown) is refused as spec-only, because the validator itself refuses them. Rule definitions and parameter bounds come from /hooks.json (registry v2).

If set, the validator requires a multiple of 100 (1% = 100).

2 · Rules (0 / 8)

Parameters, bounds and defaults are generated from the registry. Leave a parameter empty to omit it; required parameters are marked *. The 8-rule cap is the launcher's own limit — the validator enforces it again.
