+# PRD: "Firefly-style" Cloud Control Platform (working name: CloudLens)
+
+Status: DRAFT 1. Written from general knowledge of Firefly.ai (their website was
+blocked from my work environment). Please compare against firefly.ai before we build.
+
+## 1. What is this, in plain words?
+Companies rent computers, storage and databases from Amazon (AWS), Google (GCP) and
+Microsoft (Azure). Over time nobody knows exactly what they have, what it costs, or
+who changed what. Firefly is like a **smart inventory + safety camera for the cloud**:
+
+1. It **looks** at your cloud account and lists everything you own.
+2. It spots things that were made **by hand** (nobody wrote them down as code).
+3. It **writes the code** (Terraform) so those things are tracked.
+4. It **watches for changes** ("drift") and warns you.
+5. It checks **rules** (e.g. "no public storage buckets") and **cost**.
+
+## 2. Core features (the full dream list)
+| # | Feature | 4th-grade explanation |
+|---|---------|-----------------------|
+| 1 | Cloud connection | Give the app a read-only key so it can look at your cloud. |
+| 2 | Asset inventory | One big searchable list of everything you own. |
+| 3 | Unmanaged-asset finder | Highlights things made by hand, not by code. |
+| 4 | Code generator (IaC) | Turns a hand-made thing into Terraform code. |
+| 5 | Drift detection | "This changed and nobody told us!" alerts. |
+| 6 | Policy / rules engine | Checks against safety and cost rules. |
+| 7 | Cost view | Shows what each thing costs per month. |
+| 8 | Alerts | Email / Slack messages when something is wrong. |
+| 9 | Backup & restore | Saves a copy of your setup so you can rebuild it. |
+| 10 | AI helper | Ask "which servers are public?" in normal words. |
+| 11 | Teams, logins, audit log | Who can see what, and who did what. |
+
+## 3. Phased roadmap (small steps, test each one)
+
+### Phase 0 - Quick win TODAY (about 1 session)
+Goal: something you can open and click.
+- A web dashboard with a **sample** cloud inventory (fake data, clearly labeled).
+- Search, filter by cloud / type / region, and a red badge for "unmanaged".
+- Summary cards: total assets, unmanaged count, monthly cost.
+- No logins, no real cloud yet. Zero risk.
+- **Tests:** page loads with no errors -> search/filter buttons work.
+
+### Phase 1 - Real data (read-only)
+- Connect ONE real AWS account with a read-only key.
+- Replace sample data with real resources (EC2, S3, RDS first).
+- **You must:** create a read-only AWS user and give me its keys (I will walk you through it).
+- **Tests:** real API returns data -> keys never shown in the browser or saved in code.
+
+### Phase 2 - Drift + rules
+- Save a snapshot every day; show "what changed".
+- First 10 rules (public bucket, no encryption, untagged, etc.).
+- Tests: change something on purpose -> app notices.
+
+### Phase 3 - Code generation
+- Click an unmanaged item -> get Terraform code. Start with S3 + EC2 only.
+- Tests: generated code passes `terraform validate`.
+
+### Phase 4 - Alerts, cost, teams
+- Email/Slack alerts, real cost numbers, logins and roles, audit log.
+- Security review: passwords, permissions, secret storage, rate limits.
+
+### Phase 5 - Multi-cloud + AI
+- Add GCP and Azure. Add the "ask in plain English" helper (Claude API).
+- Backup & restore of cloud setups.
+
+## 4. Suggested tech (so you know, no need to learn it)
+- Frontend: Next.js + React (what Firefly-style dashboards use).
+- Backend: Node/TypeScript API, PostgreSQL database.
+- Cloud reading: official AWS / GCP / Azure SDKs.
+- Secrets: a vault / environment variables, never in code.
+
+## 5. Security rules (non-negotiable)
+- Read-only cloud keys first. Write access only in a later phase, with approval.
+- Keys stored encrypted on the server only.
+- Every phase ends with a security check before the next starts.
+
+## 6. Out of scope (for now)
+Copying Firefly's logo, name, text or design. We build our **own** product with the
+same *kind* of features. Their exact code/designs are theirs.
+
+## 7. Open questions for you
+1. Who is it for: just you, your company, or customers you will sell to?
+2. Which cloud do you use most: AWS, Google, or Azure?
+3. Do you have a cloud account we can use for testing? (If not, Phase 0 stays on fake data.)
