web

web is a cursor rule for Cursor from thearnavrustagi/marketmenow. It costs 0 tokens per session (499 once invoked), scanned A, original, MIT.

A set of rules for a FastAPI web dashboard that starts command-line jobs, tracks their progress, and sends live updates to the browser.

In plain words
What is it for?
Use it when adding dashboard routes, background jobs, WebSocket updates, platform commands, or database-backed web features.
Why use it?
It keeps the dashboard, background job queue, database access, and command-line adapters working together consistently.

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

web 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 1mo 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

Web Dashboard Rules

Architecture

The web app spawns mmn CLI commands as subprocesses — it does not call the Python pipeline directly. cli_runner.py handles subprocess execution and progress parsing. Real-time updates flow through EventHub → WebSocket.

Adapter CLIs are mounted as hidden groups in marketmenow/cli.py (hidden=True). They don't appear in mmn --help but remain callable by the web frontend. New workflows (like reddit-launch) use mmn run <name> directly.

Key Modules

  • app.py — FastAPI app with lifespan (DB pool + queue worker), WebSocket at /ws/content/{item_id}, route registration, static/output mounts.
  • cli_runner.py — run_cli() and run_cli_streaming(). Defines PLATFORM_META (JSON params) and BUILDERS (command constructors). Progress parsed via regex.
  • queue_worker.py — run_queue_loop() background task. Polls DB queue, checks per-platform rate limits, calls run_cli_streaming for each job.
  • events.py — EventHub pub/sub per content-item UUID. ProgressEvent types: phase, progress, wait, log, stderr, done, error.
  • db.py — asyncpg pool, all DB operations (content, queue, rate limits, post log).

Patterns

  • Routes live in routes/ as separate APIRouter instances.
  • Templates are Jinja2 in templates/.
  • Static assets in static/ (CSS, JS).
  • Generated output mounted at /output from settings.output_dir.

Adding a Platform to the Dashboard

  1. Add an entry to PLATFORM_META in cli_runner.py (label, modality, params).
  2. Write generate and publish CommandBuilder functions.
  3. Register them in the BUILDERS dict.
  4. No route changes needed — the generate page auto-discovers from PLATFORM_META.

Database

PostgreSQL via asyncpg. Pool initialized in lifespan, closed on shutdown. MMN_WEB_DATABASE_URL env var required.

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.
