What Corey knows.

Corey does not work from whatever it happens to recall. It works from 39 researched knowledge packs, built from 659 cited sources, each with a status, a source count and a date it has to be re-researched by. This is the full list.

Generated from Corey's own capability registry, not written by hand. When a pack is added or re-researched, this page changes with it. Packs that are still a gap are never listed here - a directory that advertises what it has not done is worth nothing.

Optimised means the pack has been researched and then put to work, so it carries what was learned in practice. Researched means the sources are gathered and cited but the pack has not yet been through real use. We do not round one up into the other.

Disciplines 29

The functions Corey works in - marketing, finance, corporate, engineering - each backed by its own researched pack rather than general recall.

Why a review date

Knowledge rots. A VAT threshold, a pricing page, an API - all of them move, and an assistant that learned them once and never checked again is worse than no assistant, because it is confidently wrong. Every pack above carries a date by which it must be re-researched. That is a commitment you can hold us to, not a claim.

Knowledge is only half of it. The other half is what Corey does with it - see the tools Corey uses and what you can ask for.
