spot: Instructions file for GitHub Copilot

.github/copilot-instructions.md

spot copilot-instructions.md is an instructions file for GitHub Copilot from orbs-network/spot. It costs 980 tokens per session, scanned C, original, MIT.

Project-specific instructions for Spot, a Solidity project for Ethereum and other blockchain networks. They describe its limit-order, TWAP, and stop-loss code, setup commands, architecture, and validation steps.

In plain words
What is it for?
Use them when bootstrapping Spot, building or testing its smart contracts, formatting code, understanding components such as order settlement and executors, or validating changes before committing.
Why use it?
They give a coding agent the project context needed to work consistently and check changes correctly. TWAP means measuring a price over a period of time rather than using one moment's price.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is orbs-network/spot's own configuration. It tells GitHub Copilot how to work on spot itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything spot configures →

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 C, and why

spot copilot-instructions.md scanned grade C with 2 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 2mo 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.

Spot DeFi Protocol - Limit Orders, TWAP, Stop-Loss

Spot is a Foundry-based Solidity project implementing a DeFi protocol for limit orders, TWAP (Time-Weighted Average Price), and stop-loss functionality on Ethereum and L2s.

Working Effectively

Bootstrap and Build Process

  1. Initialize Dependencies: git submodule update --init --recursive
  2. Install Foundry: curl -L https://foundry.paradigm.xyz | bash && foundryup
  3. Build: forge build (Compiles with 0.8.20 and 1M runs)
  4. Test: forge test
  5. Format Code: forge fmt (Always run before committing)

Validation Scenarios

forge fmt && forge test Always run the complete validation sequence after any changes.

Project Architecture

Core Components

  • OrderReactor (src/OrderReactor.sol): Order validation, epoch checking, min-out computation, and settlement.
  • RePermit (src/RePermit.sol): Permit2-style EIP-712 signatures tying witness data to order hashes.
  • Executor (src/Executor.sol): Whitelisted fillers running Multicall venue logic and handling surplus.
  • WM (src/ops/WM.sol): Allowlist management for executors and admin functions.
  • Refinery (src/ops/Refinery.sol): Utility for batching multicalls and sweeping balances by basis points.
  • Cosigner (src/ops/Cosigner.sol): Attests to trigger and market prices.

Key Libraries (src/lib/)

  • OrderLib.sol: Core order structure and validation.
  • EpochLib.sol: Time-bucket controls for TWAP cadence.
  • CosignatureLib.sol: Price attestation verification.
  • ResolutionLib.sol: Order resolution and slippage computation.
  • OrderValidationLib.sol: Order validation including chainid checks.
  • SettlementLib.sol: Settlement logic for order execution.

Critical Security Boundaries

  • Executors must be allowlisted via WM.
  • Orders require cosigned prices within freshness windows.
  • Epoch controls prevent duplicate/early fills.
  • Slippage caps protect against extreme price movements (max 50%).
  • RePermit ties spending allowances to exact order hashes.
  • Chain ID validation prevents cross-chain replay attacks.

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.
