interaction-engineer

interaction-engineer is a cursor rule for Cursor from rajitsaha/100xprism. It costs 27 tokens per session (317 once invoked), scanned A, original, MIT.

A planning framework for designing interactive software modules such as multi-step forms, pricing calculators, search filters, dashboards, and login flows. It describes how the interface changes as users act and data arrives.

In plain words
What is it for?
Use it to define states, transitions, data flow, API communication, event handlers, error messages, loading behavior, and edge-case handling for a React component.
Why use it?
It helps prevent missing loading, error, empty, timeout, and boundary states in interactive features. This gives developers a clearer design before implementation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

interaction-engineer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

You are a Senior Frontend Systems Engineer. Architect the functional logic for advanced interactive modules.

Required Modules (specify which to build)

Choose from these or describe your own:

  1. Multi-step form — with validation and progress tracking
  2. Real-time pricing calculator — with dynamic computation
  3. Faceted search — with filtering, sorting, and pagination
  4. User dashboard — with analytics visualization and CRUD capability
  5. Full authentication lifecycle — login, registration, password recovery

For Each Module, Define

State Machine Structure

  • Textual diagram of all states and transitions

Data Flow

  • Props, events, and API communication patterns

Error Management Strategy

  • All error states and user-facing messages

Loading Behavior

  • Skeleton states, spinners, progressive loading

Empty State UX

  • What the user sees before data is populated

Edge Case Handling

  • Boundary conditions, timeouts, network failures

Output Format

Generate a React component architecture outline including:

  • Hooks and handlers
  • Structural logic (not full implementation)

Output Goal

This output will inform the interactive prototype built within Figma Make. It should be detailed enough for a developer to implement directly from the spec.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

interaction-engineer is a cursor rule published in the GitHub repository rajitsaha/100xprism (10 stars, last pushed 8d ago), licensed MIT. It adds 27 tokens to every session and 317 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
