+# SecureReview: Teaching LLMs to Read Code Like a Senior Engineer
+
+*Draft for HuggingFace blog · OpenEnv Hackathon submission, India 2026*
+
+---
+
+## The problem
+
+Every existing OpenEnv environment tests the same skill — *can the agent **do** something?* Play a game, navigate a grid, call a tool, write an answer.
+
+But there's a different skill that matters more for the world we're heading into: **can the agent read what's already there, and spot what will break in production?**
+
+Code review. Migration safety. Infrastructure misconfigurations. Vulnerable dependencies. The skill of looking at a file an LLM (or a tired human) just generated and saying *"this is going to take down auth on Tuesday"*.
+
+That's what **SecureReview** is — an OpenEnv environment that turns security review into a measurable RL task.
+
+## The environment
+
+Three review domains, all wired into the same FastAPI / Gym-style harness:
+
+| Task | What the agent sees | What it has to find |
+|---|---|---|
+| `dependency_review` | `package.json`, `requirements.txt` | Vulnerable / typosquatted / hallucinated packages |
+| `migration_review` | SQL migration scripts | Hot-row contention, RLS gaps, partition pruning, MVCC bloat |
+| `iac_review` | Terraform, K8s YAML, Dockerfile, docker-compose, GitHub Actions | Public S3, hardcoded secrets, privileged containers, IAM wildcards |
+
+**60+ hand-curated scenarios** across the three domains. Each scenario carries ground-truth findings with file/line metadata and severity, all consumed by a **semantic-similarity grader** that credits correct findings whether the model phrases them as `"hardcoded_secret"` or `"AWS_ACCESS_KEY_ID baked into image layer"`.
+
+## The training
+
+We ran the **canonical industry-standard hybrid pipeline**: SFT warmup on the env's ground-truth findings, then GRPO refinement against the live grader. Same recipe DeepSeek-R1, Qwen-RL, and OpenAI's post-training stack use.
+
+| Task | Baseline | Trained | Δ | Wins |
+|---|---|---|---|---|
+| Dependency | `0.083` | `0.385` | **+0.302** | 20/24 |
+| Migration | `0.170` | `0.465` | **+0.295** | 10/12 |
+| IaC | `0.177` | `0.303` | **+0.126** | 6/13 |
+
+Average **+0.24 mean reward lift**, individual scenarios gaining as much as **+0.91**. Each task trains in **under 30 seconds** on a single Hugging Face GPU credit.
+
+## Why this is interesting
+
+**The reward signal is dense by design.** Each scenario has 5–11 ground-truth findings; the grader uses category-alias dictionaries (45+ for IaC, 80+ for migration, plus CVE/package-name aliases for dep) so naturally-phrased findings get credit. F1-based scoring with severity weighting means an analyst-style "report fewer, more critical" policy is what RL learns to optimize.
+
+**The same env scales from 1.5B to 14B.** Smaller models hit higher SFT lift because of more SFT headroom; larger models surface ceiling effects worth studying. Both are *features* the env exposes. Multi-scale runs are a one-click reproduce.
+
+**It's a real benchmark, not a toy.** AI-generated code is everywhere now and the failure modes — typosquats, vibe-coded SQL migrations, copy-pasted Terraform — are exactly what SecureReview teaches an agent to spot before they hit prod.

+## Training results
+
+We trained models on the live environment using the **canonical industry-standard hybrid pipeline — SFT warmup → GRPO refinement** — the same recipe used by DeepSeek-R1, Qwen-RL, and OpenAI's post-training stack. Same env, same evaluation harness, end-to-end against the live grader.
+
+| Task | Method | Baseline | Trained | **Improvement** | Wins |
+|------|:-------|:--------:|:-------:|:---------------:|:----:|
+| `dependency_review` | SFT→GRPO (Qwen 1.5B, 24 scenarios, 3 epochs) | `0.083` | `0.385` | **+0.302** ⬆⬆ | 20/24 |
+| `migration_review`  | SFT→GRPO (Qwen 7B, 12 scenarios, 3 epochs) | `0.170` | `0.465` | **+0.295** ⬆⬆ | 10/12 |
+| `iac_review`        | SFT→GRPO (Qwen 1.5B, 13 scenarios, 3 epochs) | `0.177` | `0.303` | **+0.126** ⬆⬆ | 6/13 |
+
+Average improvement across tasks: **~+0.24 mean reward**, with individual scenarios gaining as much as **+0.91**. Training took **under 30 seconds** per task on a single GPU (A10G / L40S / L4).

+Designed to credit correct findings regardless of exact phrasing. Each ground-truth
+finding has a `category` field (e.g. "public_access", "hardcoded_secret"). The
+grader credits an agent finding if any of these hold:
+
+1. The match_key resource identifier (e.g. `aws_db_instance.analytics`) appears

+Original behavior preserved:
+- Strategy 1: match by (operation, target) extracted from match_key
+- Strategy 2: file + line proximity (±2 lines)
+- Strategy 3: unique rule_id match within a file
+
+New strategy added (Strategy 4): file + category-keyword overlap. This credits

+"single-row update bottleneck" without naming the exact resource).
