# 100-Point Solidity Audit & Optimization Prompt

Production-ready, local CI (Drone / Woodpecker) friendly audit bundle for Hardhat + Foundry + Dockerized security toolchains.

## Purpose
Use this prompt as the single source-of-truth for automated LLM agents, CI pipeline steps, or manual auditors. It describes the 100-point scoring rubric, how to run the tests locally in Docker, and how to produce the final scored `summary.md` and `summary.json`.

---

## Quick start (local)
Prerequisites:
- Docker & Docker Compose
- Drone or Woodpecker (server + runner) installed locally, or use the `drone-runner-docker` image
- Node 20+, Foundry (forge), Python 3.10+

Run locally (example using docker-compose):

```bash
# build and run analyzer containers (optional)
docker compose up --build --detach

# run foundry tests
docker run --rm -v $(pwd):/src -w /src ghcr.io/foundry-rs/foundry:latest forge test --gas-report --ffi --json > reports/forge-gas.json

# run hardhat tests
docker run --rm -v $(pwd):/src -w /src node:20-alpine sh -c "npm ci && npx hardhat test --network hardhat --json > reports/hardhat-test.json"

# run slither (example)
docker run --rm -v $(pwd):/src -w /src trailofbits/eth-security-toolbox:latest slither . --json reports/slither.json

# run echidna (example)
docker run --rm -v $(pwd):/src -w /src trailofbits/echidna:latest echidna-test contracts/ --config echidna.yaml --json > reports/echidna.json

# then merge and score
python3 scripts/merge_reports.py --reports reports --out reports/merged.json
python3 scripts/score_audit.py --input reports/merged.json --out summary.md --json summary.json
```

---

## 100-Point Checklist (short)
(Full checklist is intentionally compacted here — the scoring script uses the same criteria.)

A. Architecture & Design (10)
B. Security Vulnerability Analysis (25)
C. Gas & Performance Optimization (20)
D. Testing & Coverage (15)
E. Tool-Based Analysis (20)
F. Documentation & Clarity (5)
G. CI/CD & Automation (5)
H. Foundry + Hardhat Parity Validation (5)
I. Code Quality & Readability (5)
J. Advanced Protocol-Specific Checks (10)
K. Deployment & Production Readiness (10)

(See repo `README` or `scripts/score_audit.py` for the detailed mapping of checks → points.)

---

## CI Integration (Drone / Woodpecker local)
This repo provides `ci/.drone.yml` and `ci/.woodpecker.yml` for local CI runners. Both files execute the same pipeline: compile, tests (foundry/hardhat), slither, echidna, collect reports, merge, score, and upload artifacts.

---

## Output
- `summary.md` — human readable scored audit with fixes and references
- `summary.json` — structured audit with per-check boolean/status and weight
- `reports/*` — raw tool outputs

---

## Notes & Best Practices
- Pin Docker images in your private registry for reproducibility
- Use `--json` outputs where supported so `merge_reports.py` can parse them
- Consider running `forge snapshot` and `npx hardhat node --fork` for mainnet fork tests
