MARSYS: Instructions file for GitHub Copilot

.github/instructions/Framework_Development_Guide.instructions.md

MARSYS Framework_Development_Guide.instructions.md is an instructions file for GitHub Copilot from rezaho/MARSYS. It costs 2,483 tokens per session, scanned A, original, Apache-2.0.

A repository-specific development guide for MARSYS, a multi-agent reasoning system, covering its architecture, classes, communication rules, and coding constraints.

In plain words
What is it for?
It is for guiding changes to MARSYS agents, model abstractions, infrastructure, browser automation, and related source modules.
Why use it?
It gives coding agents the project rules they need to avoid breaking message formats, registries, memory order, JSON contracts, or asynchronous behavior.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is rezaho/MARSYS's own configuration. It tells GitHub Copilot how to work on MARSYS 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 MARSYS configures →

Borrowing it

Nothing to install: this file belongs to rezaho/MARSYS. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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

MARSYS Framework_Development_Guide.instructions.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 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.

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.

Multi-Agent Reasoning Systems (MARSYS) – Framework Development Guide (AI Instruction Set)

This file provides domain knowledge, coding standards, and project preferences that every AI agent / Copilot must always follow when editing this repository.


0. Golden Principle

Do not break invariants (message format, registry, memory order, JSON contracts, async rules).


1. Layered Architecture (mental model)

Application  ─┐
Agents       ─┤  (BaseAgent → Agent/BrowseAgent/LearnableAgent/…)
Model Abstr. ─┤  (BaseLLM | BaseVLM | BaseAPIModel)
Infra        ─┘  (Registry, Memory, Utils, Monitoring)

• NEVER leak implementation details across layers.
• Agents interact with models only through model.run(...).


2. Core Classes & Responsibilities

Class / Module Purpose Key Methods
BaseAgent Abstract foundation for all agents _run(), auto_run(), invoke_agent(), progress logging, tool schema generation
Agent Standard agent implementation _run(), auto_run(), OpenAI JSON mode responses, tool/peer invocation
BrowserAgent Web automation specialist Playwright integration, page navigation, element interaction
BaseLearnableAgent Learning-enabled agent base Reward tracking, experience replay, RL integration
LearnableAgent Concrete learnable agent Policy updates, learning from interactions
MemoryManager Central memory coordinator update_memory(), retrieve_*(), to_llm_format(), update_from_response()
Message OpenAI-compatible message .to_llm_dict(), .from_response_dict(), role validation
ModelConfig Model configuration (Pydantic) Provider setup, parameter validation, environment integration
BaseAPIModel HTTP-based model wrapper API calls, retry logic, rate limiting, streaming
BaseLLM Local transformer models GPU acceleration, tokenization, generation
BaseVLM Vision-language models Image preprocessing, multimodal input handling
AgentRegistry Global agent lifecycle manager Registration, weak references, thread-safe operations
RequestContext Async context propagation Depth tracking, interaction counting, progress monitoring
BaseCrew Multi-agent orchestration Task distribution, result aggregation, resource cleanup
GRPOTrainer Reinforcement learning trainer Policy optimization, TRL integration, reward processing

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.
