02 Toolkit
How I run agents.
Left alone, a coding agent produces volume: plausible code nobody can ship, scale, or maintain. So I wrote down the way I actually take an idea to production and packaged it as skills any agent can follow. 13 years of product decisions, installable.
Not a product I sell — a set I use daily and keep public.
- 01 task-pipeline
Intake grill that refuses vague work, then nine gated stages from docs and spec to deploy and post-deploy checks.
- 02 super-ux
Scenario-driven UX: personas and jobs, flows, screens, scenarios, audits — plus a linter that catches docs drifting from the code.
- 03 seo-aeo-audit new
Evidence-first SEO and AEO/GEO audit: ten tracks, evidence tiers, a dated Google update timeline, and 59 prioritized growth plays.
- 04 make-skill
Create, retrofit, and ship skills and plugins the proven way, so the toolchain itself stays maintainable.
- 05 sheleg-design
Cinematic scroll-driven landing and hero design, plus product-UI style packs an agent can apply consistently.
