Help the user understand the current topic of conversation visually. Skip the preamble. Keep prose short by leaving out detail the visual already carries, not by compressing sentences. Pick the smallest view that makes the key point clear.
- Show logic or an algorithm as pseudocode:
on(save)
if content is unchanged
return cached result
write new content
return fresh result
- Show runtime control flow as a call tree:
submitForm
createSession
persistPrompt
launchAgent
navigateToSession
- Show UI structure as a component tree, including state and module boundaries that matter:
<SessionPage> (apps/example/src/routes/session.tsx)
useSessionEvents()
<SessionToolbar>
<RunSkillButton> (packages/ui)
- Show file responsibility or a broad refactor as a shallow file tree:
src/
├── commands/ # parses user actions
├── sessions/ # owns session state
└── transport/ # sends API requests
- Show component interaction, control flow, or data flow with Mermaid:
sequenceDiagram
participant User
participant UI
participant Daemon
User->>UI: choose command
UI->>Daemon: send expanded prompt
Daemon-->>UI: stream result
- Use
diffwhen the point is what changes and the surrounding shape already exists. Match the diff shape to the topic.
For a component change:
<SessionPage>
useSessionEvents()
<SessionToolbar>
+ <RunSkillButton />
<SessionTimeline>
+ <SkillResultCard />
For a file-layout change:
src/
├── commands/
+│ └── show-me.ts # expands the slash command
├── sessions/
-└── transport.ts
+└── transport/
+ ├── client.ts
+ └── stream.ts
For a call-tree or call-stack change:
submitForm
createSession
persistPrompt
+ expandSkillMention
launchAgent
- navigateToSession
+ navigateToSession
+ subscribeToEvents
For a state or control-flow change:
on(save)
- write content
+ if content is unchanged
+ return cached result
+ write new content
+ invalidate cache
- Show the whole block when most of it is new, when omitted context would hide ownership or order, or when the user needs a copyable target shape:
function expandSkill(command: string): string {
const skillName = command.slice(1)
return `use the ${skillName} skill`
}
- For a visual UI, layout, state comparison, or concept too dense for Mermaid, write one focused HTML file — a diagram, an infographic, or a short slide deck, whichever fits the point. Match the product's colors, type, spacing, and components; use real labels and data; support desktop and mobile. Then open or preview it for the user with the environment's available file-opening tool.
guidance
Place each visual next to the short text it supports. Keep only the calls, files, props, states, and boundaries needed to answer the user's current question or the options to resolve the current discussion point.
Use only the views the question needs. Prefer a few focused visuals over one that needs scrolling. For a long workflow, group the overview into three to five phases and expand only the decision points that matter. Keep a top-down Mermaid overview to roughly a dozen nonblank lines; split or group anything larger. Do not lead with a comprehensive diagram and then repeat it in smaller views.
