Ask Codex something
In words. It picks the call, and the answer is the one a person sees on the report.
- What should I fix first on example.com?mttr_brief({ site: "example.com" })
- Fix the top issue, then have mttr read the site again.mttr_rescan({ site: "example.com" })
- Who am I up against, and what do they cover that I don’t?mttr_competitors({ site: "example.com" })

What you ask Codex

In words. It picks mttr’s tool for it.

Fix what is worth the most on my site.: It reads the brief, works the top fix across every page it applies to, and shows you the diff.
Did my last deploy break anything?: It asks mttr what changed since the read before, and lists any rule that now fails.
Write the answer-first opening mttr wants on /pricing.: It reads what the rule asks, rewrites the opening, and has mttr check the page.
Who am I up against?: It lists the sites doing the same work nearby, and what they cover that you do not.

Using another agent?

Codex is its maker’s product. mttr is independent and not affiliated with it. A score says pages are well formed. It does not say an assistant cites the site.
