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

jayrah web-ui.instructions.md 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 2d 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.

Web UI Development Instructions

Development Workflow

The Jayrah web UI is built with FastAPI backend and vanilla HTML/CSS/JavaScript frontend.

Running the Web Server

Use the Makefile command for development:

make web

This starts the web server with:

  • Auto-reload enabled: Changes to files automatically restart the server
  • Reload directory: Watches ./jayrah/ui/web for changes
  • Hot reload: No need to manually kill/restart the server during development

File Structure

  • jayrah/ui/web/server.py - FastAPI backend server
  • jayrah/ui/web/index.html - Frontend HTML/CSS/JavaScript (single page app)

Key Features Implemented

  • Full screen layout: Uses entire viewport with responsive design
  • Horizontal scrolling: Issue list table scrolls horizontally by default
  • Custom fields support: Displays Jira custom fields same as TUI
  • Markdown rendering: Converts Jira markup to HTML using marked.js
  • Real-time search: Debounced search with backend filtering
  • Professional UI: Inbox-style layout matching TUI workflow

Development Notes

  • No manual restarts needed: Thanks to --reload, just save files and refresh browser
  • Shared logic: Common functions moved to jayrah/ui/shared_helpers.py to avoid circular imports
  • Config compatibility: Uses same ~/.config/jayrah/config.yaml as TUI
  • API endpoints:
    • /api/issues - List issues with optional search
    • /api/issue/{key} - Get issue details with custom fields config
    • /api/config - Get configuration including custom fields
  • Always use make web which does auto reload and hot reload

Testing Changes

  1. Make changes to server.py or index.html
  2. Save the file (uvicorn will auto-reload)
  3. Refresh browser at http://127.0.0.1:8000
  4. No need to kill/restart the server process

External Dependencies

  • marked.js: Loaded from CDN for Jira markdown → HTML conversion
  • FastAPI: Backend framework
  • Uvicorn: ASGI server with hot reload capability

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.
