floom AGENTS.md

Project instructions for Floom, a self-hosted system for running AI workers in isolated environments. They describe setup, local development, testing, architecture, and required secrets.

In plain words
What is it for?
Use them to set up Floom, start its backend and frontend, understand its structure, and follow its development and testing rules.
Why use it?
They give the coding agent the project's startup commands and safety rules, including when it must ask for credentials.

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

floom AGENTS.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.

How it starts

The opening of the file, as written. The whole thing — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — Floom

Self-hosted runtime for AI workers (script- or agent-mode jobs that run in E2B sandboxes). FastAPI + SQLite backend (apps/api), Next.js frontend (apps/web), MCP server (apps/mcp). Deeper docs: README.md, ARCHITECTURE.md, CONTRIBUTING.md.

Setup (once)

  • macOS/Linux: ./scripts/setup.sh · Windows: .\scripts\setup.ps1
  • Creates the backend venv, installs backend + frontend deps, scaffolds apps/api/.env.
  • Setup cannot complete without secrets only the user has. At minimum OPENAI_API_KEY + E2B_API_KEY (or Bedrock: WORKEROS_*_MODEL=bedrock/... plus AWS creds). Ask the user for these — never invent, guess, or commit them.

Run

  • macOS/Linux: ./scripts/dev.sh · Windows: .\scripts\dev.ps1
  • Starts backend (http://localhost:8000) + frontend (http://localhost:3000).
  • It blocks — it runs both servers in the foreground until Ctrl+C. If you are an agent, run it in the background, or start the two halves yourself: cd apps/api && ./venv/bin/python main.py (Windows: venv\Scripts\python.exe main.py) and cd apps/web && npm run dev.
  • No auth secret is needed for local dev; the first sign-in creates the account.

Test / lint

  • Backend: cd apps/api && ./venv/bin/python -m pytest tests/ -q
  • Frontend: cd apps/web && npm test (vitest) · npm run build · npm run lint

Hard rules (do not violate)

  • Never commit apps/api/.env, the root .env, or data/ — they hold API keys, secrets, OAuth tokens, sessions, and PATs. They are gitignored; keep it so.
  • No telemetry by default — never commit a key. The repo ships analytics wiring (PostHog) that is inert unless a key is set: with POSTHOG_API_KEY / NEXT_PUBLIC_POSTHOG_KEY unset, nothing is collected and no data leaves the instance — there is no key and no destination in the source. An operator who wants analytics sets their own PostHog project key (events route to their project). Keep it that way: never commit a key, and never send raw run input/output, secret names/values, connection tokens, or PII.
  • Don't let worker edits auto-push to this public repo. For real work point FLOOM_WORKERS_DIR / WORKEROS_WORKSPACE_DIR outside the checkout; the engine refuses to version into its own source tree by default.
  • No em-dashes (—) in web copy strings (npm run lint:emdash fails the build) or in .ps1 scripts (Windows PowerShell 5.1 mis-decodes them). Keep scripts ASCII.

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.
