feature

feature is a command for coding agents from senaiverse/reactnative-expo-ai-agent-system-workflow. It costs 12 tokens per session (555 once invoked), scanned C, original, MIT.

A guided workflow for adding a new software feature, from planning and security review through implementation and testing. It coordinates several specialist coding agents and follows the project’s existing conventions.

In plain words
What is it for?
Use it to plan and build features involving components, hooks, services, business logic, typed code, state management, or iOS and Android compatibility.
Why use it?
It reduces the chance of missing affected files, dependencies, security risks, or platform differences when a feature touches many parts of an application.

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 C, and why

feature scanned grade C with 1 finding 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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Feature Implementation Workflow

Implements: $ARGUMENTS

Execution Plan

Execute the following multi-agent workflow:

Phase 1: Planning & Analysis

  1. Grand Architect Analysis

    • Invoke @grand-architect to break down the feature
    • Analyze architectural impact
    • Identify affected files and components
    • Assess complexity and risks
  2. Feature Impact Assessment

    • Estimate implementation time
    • Identify dependencies
    • Determine if breaking changes are involved

Phase 2: Security & Architecture Review

  1. Security Audit (if feature involves):

    • User data, authentication, payments, or sensitive operations
    • Invoke @security-specialist for OWASP Mobile Top 10 check
  2. State Management Planning

    • Determine state architecture needed
    • Plan Redux/Context integration
    • Design data flow

Phase 3: Implementation

  1. Create Feature Structure

    • Generate necessary files (components, hooks, services)
    • Follow project conventions from CLAUDE.md
  2. Write Core Logic

    • Implement business logic
    • Add proper TypeScript types
    • Follow design system tokens
  3. Cross-Platform Validation

    • Ensure iOS and Android compatibility
    • Handle platform-specific cases if needed

Phase 4: Quality Assurance

  1. Generate Tests (@test-generator)

    • Unit tests for business logic
    • Component tests for UI
    • E2E tests if critical flow
  2. Accessibility Check (@a11y-enforcer)

    • Validate all interactive elements
    • Check color contrast
    • Verify touch targets
  3. Performance Check (@performance-prophet)

    • Predict performance impact
    • Check for potential bottlenecks
    • Validate bundle size increase

Phase 5: Final Review

  1. Code Review (/@review)

    • Run comprehensive review
    • Fix any issues found
  2. Documentation

    • Add inline comments for complex logic
    • Update CLAUDE.md if needed

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.

feature is a command published in the GitHub repository senaiverse/reactnative-expo-ai-agent-system-workflow (126 stars, last pushed 3mo ago), licensed MIT. It adds 12 tokens to every session and 555 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
