The agent’s behavior on your site is steered by three kinds of context, all managed under Delta → Context.
Skills
Skills are playbooks for one kind of work. The agent loads a skill when the task calls for it. Delta ships a default set; each site holds its own copy, so you or the agent can edit them, add new ones, or restore the defaults. The agent asks for confirmation before it changes an existing skill.
| Skill | Purpose |
|---|---|
build-from-prompt |
Build a new site from a written brief. |
clone-from-url |
Recreate a live site from its URL (requires a browser tool). |
build-from-visual |
Build from screenshots, mockups, or Figma exports. |
design |
Change tokens, site CSS, components, or notes. |
components |
Define and maintain design-system components. |
site-foundation |
Set up headers, footers, navigation, and site identity. |
blog-and-conditions |
Set up blogs, archives, singles, and CPT listings. |
content-types |
Custom post types and fields through a supported plugin. |
contact-forms |

mobile-first / mobile-responsiveness |
Mobile-first or desktop-first build process. |
polish-and-verify |
Visual, spacing, and accessibility finish pass. |
troubleshooting |
Failure diagnosis and support reports. |
session-router |
Internal: picks the right skill on ambiguous requests. |
Rules
Rules are short constraints that always apply, with the same editing model as skills. Delta ships five, including entry-html-no-loops (no {{#posts}} in page HTML) and semantic-accessible (landmarks, heading order, accessible labels).
Guardrails
Guardrails belong to the theme. You can switch each one on or off under Context → Guardrails, but their text is not editable, by you or by the agent. Most of them make the agent ask before sensitive actions:
| Guardrail | Effect |
|---|---|
| Session protocol | Sets the required call order at session start. |
| Design scope | Decides when a session includes design work. |
| List paging | Keeps reads paged instead of full-catalog dumps. |
| Layer hierarchy | Prefers design system → components → templates over one-off styles. |
| WordPress and Delta truth | Cross-layer facts the agent must respect. |
| Prefer design tokens | Tokens over hard-coded values. |
| Verify before done | Read back and check after every meaningful write. |
| Design notes | Ask before changing the design-system notes, or before a snapshot restore (which overwrites them). |
| Confirm primary guideline changes | Ask before changing existing skills or rules. |
| Confirm plugin installs | Ask before installing, activating, updating, or deleting plugins. |
| Destructive care | Confirm before replace or fan-out operations. |
