feat(workflow): implement workflow graph system with node types and agent vertex
- Added `mod.rs` for the workflow graph system, outlining the structure and usage. - Introduced `node.rs` defining various node types (Agent, Tool, Router, etc.) and their configurations. - Created `vertices/agent.rs` implementing the `AgentVertex` for LLM-based processing with tool calling capabilities. - Added `vertices/mod.rs` to organize vertex implementations. - Implemented serialization and deserialization for node configurations using Serde. - Included tests for node configurations and agent vertex functionality.

# Repository Guidelines
|
||||
|
||||
## Project Structure & Module Organization
|
||||
- `research_agent/` contains the core Python agents, prompts, tools, and subagent utilities.
|
||||
- `skills/` holds project-level skills as `SKILL.md` files (YAML frontmatter + instructions).
|
||||
- `research_workspace/` is the agent’s working filesystem for generated outputs; keep it clean or example-only.
|
||||
- `deep-agents-ui/` is the Next.js/React UI with source under `deep-agents-ui/src/`.
|
||||
- `deepagents_sourcecode/` vendors upstream library sources for reference and comparison.
|
||||
- `rust-research-agent/` is a standalone Rust tutorial agent with its own build/test flow.
|
||||
- `langgraph.json` defines the LangGraph deployment entrypoint for the research agent.
|
||||
|
||||
## Build, Test, and Development Commands
|
||||
Use the UI commands from `deep-agents-ui/` when working on the frontend:
|
||||
```bash
|
||||
cd deep-agents-ui && yarn install # install deps
|
||||
cd deep-agents-ui && yarn dev # run local UI
|
||||
cd deep-agents-ui && yarn build # production build
|
||||
cd deep-agents-ui && yarn lint # eslint checks
|
||||
cd deep-agents-ui && yarn format # prettier format
|
||||
```
|
||||
Python tooling is configured in `pyproject.toml` (ruff + mypy):
|
||||
```bash
|
||||
uv run ruff format .
|
||||
uv run ruff check .
|
||||
uv run mypy .
|
||||
```
|
||||
|
||||
## Coding Style & Naming Conventions
|
||||
- Python: follow ruff defaults and Google-style docstrings (see `pyproject.toml`); prefer `snake_case` modules and functions.
|
||||
- TypeScript/React: keep `PascalCase` for components, `camelCase` for hooks/utilities; rely on ESLint + Prettier (Tailwind plugin).
|
||||
- Skill definitions: keep one skill per directory with a `SKILL.md` entrypoint and clear, task-focused naming.
|
||||
|
||||
## Testing Guidelines
|
||||
- There are no repository-wide tests for `research_agent/` yet; add `pytest` tests when introducing new logic.
|
||||
- Subprojects have their own suites: see `deepagents_sourcecode/libs/*/Makefile` and `rust-research-agent/README.md` for `make test` or `cargo test`.
|
||||
|
||||
## Commit & Pull Request Guidelines
|
||||
- Git history uses short, descriptive messages in English or Korean with no enforced prefix; keep summaries concise and imperative.
|
||||
- For PRs, include: a brief summary, testing notes (or “not run”), linked issues, and UI screenshots for frontend changes.
|
||||
|
||||
## Configuration & Secrets
|
||||
- Copy `env.example` to `.env` for API keys; never commit secrets.
|
||||
- UI-only keys can be set via `NEXT_PUBLIC_LANGSMITH_API_KEY` in `deep-agents-ui/`.

|
||||
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
||||
|
||||
## Project Overview
|
||||
|
||||
A multi-agent research system demonstrating **FileSystem-based Context Engineering** using LangChain's DeepAgents framework. The system includes:
|
||||
- **Python DeepAgents**: LangChain-based multi-agent orchestration with web research capabilities
|
||||
- **Rust `rig-deepagents`**: A port/reimagining using the Rig framework with Pregel-inspired graph execution
|
||||
|
||||
The system enables agents to conduct web research, delegate tasks to sub-agents, and generate comprehensive reports with persistent filesystem state.
|
||||
|
||||
## Development Commands
|
||||
|
||||
### Python Backend
|
||||
|
||||
```bash
|
||||
# Install dependencies (uses uv package manager)
|
||||
uv sync
|
||||
|
||||
# Start LangGraph development server (API on localhost:2024)
|
||||
langgraph dev
|
||||
|
||||
# Linting and formatting
|
||||
ruff check research_agent/
|
||||
ruff format research_agent/
|
||||
|
||||
# Type checking
|
||||
mypy research_agent/
|
||||
```
|
||||
|
||||
### Frontend UI (deep-agents-ui/)
|
||||
|
||||
```bash
|
||||
cd deep-agents-ui
|
||||
yarn install
|
||||
yarn dev # Dev server on localhost:3000
|
||||
yarn build # Production build
|
||||
yarn lint # ESLint
|
||||
yarn format # Prettier
|
||||
```
|
||||
|
||||
### Interactive Notebook Development
|
||||
|
||||
```bash
|
||||
# Open Jupyter for interactive agent testing
|
||||
jupyter notebook DeepAgent_research.ipynb
|
||||
```
|
||||
|
||||
The `research_agent/utils.py` module provides Rich-formatted display helpers for notebooks:
|
||||
- `format_messages(messages)` - Renders messages with colored panels (Human=blue, AI=green, Tool=yellow)
|
||||
- `show_prompt(text, title)` - Displays prompts with XML/header syntax highlighting
|
||||
|
||||
### Rust `rig-deepagents` Crate
|
||||
|
||||
```bash
|
||||
cd rust-research-agent/crates/rig-deepagents
|
||||
|
||||
# Run all tests (159 tests)
|
||||
cargo test
|
||||
|
||||
# Run tests for a specific module
|
||||
cargo test pregel:: # Pregel runtime tests
|
||||
cargo test workflow:: # Workflow node tests
|
||||
cargo test middleware:: # Middleware tests
|
||||
|
||||
# Linting (strict, treats warnings as errors)
|
||||
cargo clippy -- -D warnings
|
||||
|
||||
# Build with optional features
|
||||
cargo build --features checkpointer-sqlite
|
||||
cargo build --features checkpointer-redis
|
||||
cargo build --features checkpointer-postgres
|
||||
```
|
||||
|
||||
### Running the Full Stack
|
||||
|
||||
1. Start backend: `langgraph dev` (port 2024)
|
||||
2. Start frontend: `cd deep-agents-ui && yarn dev` (port 3000)
|
||||
3. Configure UI with Deployment URL (`http://127.0.0.1:2024`) and Assistant ID (`research`)
|
||||
|
||||
## Required Environment Variables
|
||||
|
||||
Copy `env.example` to `.env`:
|
||||
- `OPENAI_API_KEY` - For gpt-4.1 model
|
||||
- `TAVILY_API_KEY` - For web search functionality
|
||||
- `LANGSMITH_API_KEY` - Optional, format `lsv2_pt_...` for tracing
|
||||
- `LANGSMITH_TRACING` / `LANGSMITH_PROJECT` - Optional tracing config
|
||||
|
||||
## Architecture
|
||||
|
||||
### Multi-SubAgent System
|
||||
|
||||
The system uses a three-tier agent hierarchy with two distinct SubAgent types:
|
||||
|
||||
```
|
||||
Main Orchestrator Agent (agent.py)
|
||||
│
|
||||
├── FilesystemBackend (../research_workspace)
|
||||
│ └── Persistent state via virtual filesystem
|
||||
│
|
||||
└── SubAgents
|
||||
├── researcher (CompiledSubAgent) ─ Autonomous DeepAgent
|
||||
│ └── "Breadth-first, then depth" research pattern
|
||||
├── explorer (Simple SubAgent) ─ Fast read-only exploration
|
||||
└── synthesizer (Simple SubAgent) ─ Research result integration
|
||||
```
|
||||
|
||||
**CompiledSubAgent vs Simple SubAgent:**
|
||||
|
||||
| Type | Definition | Execution | Use Case |
|
||||
|------|------------|-----------|----------|
|
||||
| CompiledSubAgent | `{"runnable": CompiledStateGraph}` | Multi-turn autonomous | Complex research with self-planning |
|
||||
| Simple SubAgent | `{"system_prompt": str}` | Single response | Quick tasks, file ops |
|
||||
|
||||
### Core Components
|
||||
|
||||
**`research_agent/agent.py`** - Orchestrator configuration:
|
||||
- LLM: `ChatOpenAI(model="gpt-4.1", temperature=0.0)`
|
||||
- Creates researcher via `get_researcher_subagent()` (CompiledSubAgent)
|
||||
- Defines `explorer_agent`, `synthesizer_agent` (Simple SubAgents)
|
||||
- Assembles `ALL_SUBAGENTS = [researcher_subagent, *SIMPLE_SUBAGENTS]`
|
||||
|
||||
**`research_agent/researcher/`** - Autonomous researcher module:
|
||||
- `agent.py`: `create_researcher_agent()` factory and `get_researcher_subagent()` wrapper
|
||||
- `prompts.py`: `AUTONOMOUS_RESEARCHER_INSTRUCTIONS` with three-phase workflow (Exploratory → Directed → Synthesis)
|
||||
|
||||
**Backend Factory Pattern** - The `backend_factory(rt: ToolRuntime)` function demonstrates the recommended pattern:
|
||||
```python
|
||||
CompositeBackend(
|
||||
default=StateBackend(rt), # In-memory state (temporary files)
|
||||
routes={"/": fs_backend} # Route "/" paths to FilesystemBackend
|
||||
)
|
||||
```
|
||||
This enables routing: paths starting with "/" go to persistent local filesystem (`research_workspace/`), others use ephemeral state.
|
||||
|
||||
**`research_agent/prompts.py`** - Prompt templates:
|
||||
- `RESEARCH_WORKFLOW_INSTRUCTIONS` - Main workflow (plan → save → delegate → synthesize → write → verify)
|
||||
- `SUBAGENT_DELEGATION_INSTRUCTIONS` - When to parallelize (comparisons) vs single agent (overviews)
|
||||
- `EXPLORER_INSTRUCTIONS` - Fast read-only exploration with filesystem tools
|
||||
- `SYNTHESIZER_INSTRUCTIONS` - Multi-source integration with confidence levels
|
||||
|
||||
**`research_agent/tools.py`** - Research tools:
|
||||
- `tavily_search(query, max_results, topic)` - Searches web, fetches full page content, converts to markdown
|
||||
- `think_tool(reflection)` - Explicit reflection step for deliberate research
|
||||
|
||||
**`langgraph.json`** - Deployment config pointing to `./research_agent/agent.py:agent`
|
||||
|
||||
### Context Engineering Pattern
|
||||
|
||||
The filesystem acts as long-term memory:
|
||||
1. Agent reads/writes files in virtual `research_workspace/`
|
||||
2. Structured outputs: reports, TODOs, request files
|
||||
3. Middleware auto-injects filesystem and sub-agent tools
|
||||
4. Automatic context summarization for token efficiency
|
||||
|
||||
### DeepAgents Auto-Injected Tools
|
||||
|
||||
The `create_deep_agent()` function automatically adds these tools via middleware:
|
||||
- **TodoListMiddleware**: `write_todos` - Task planning and progress tracking
|
||||
- **FilesystemMiddleware**: `ls`, `read_file`, `write_file`, `edit_file`, `glob`, `grep` - File operations
|
||||
- **SubAgentMiddleware**: `task` - Delegate work to sub-agents
|
||||
- **SkillsMiddleware**: Progressive skill disclosure via `skills/` directory
|
||||
|
||||
Custom tools (`tavily_search`, `think_tool`) are added explicitly in `agent.py`.
|
||||
|
||||
### Skills System
|
||||
|
||||
Project-level skills are located in `PROJECT_ROOT/skills/`:
|
||||
- `academic-search/` - arXiv paper search with structured output
|
||||
- `data-synthesis/` - Multi-source data integration and analysis
|
||||
- `report-writing/` - Structured report generation
|
||||
- `skill-creator/` - Meta-skill for creating new skills
|
||||
|
||||
Each skill has a `SKILL.md` file with YAML frontmatter (name, description) and detailed instructions. The SkillsMiddleware uses Progressive Disclosure: only skill metadata is injected into the system prompt at session start; full skill content is read on-demand when needed.
|
||||
|
||||
### Research Workflow
|
||||
|
||||
**Orchestrator workflow:**
|
||||
```
|
||||
Plan → Save Request → Delegate to Sub-agents → Synthesize → Write Report → Verify
|
||||
```
|
||||
|
||||
**Autonomous Researcher workflow (breadth-first, then depth):**
|
||||
```
|
||||
Phase 1: Exploratory Search (1-2 searches) → Identify directions
|
||||
Phase 2: Directed Research (1-2 searches per direction) → Deep dive
|
||||
Phase 3: Synthesis → Combine findings with source agreement analysis
|
||||
```
|
||||
|
||||
Sub-agents operate with token budgets (5-6 max searches) and explicit reflection loops (Search → think_tool → Decide → Repeat).
|
||||
|
||||
## Rust `rig-deepagents` Architecture
|
||||
|
||||
The Rust crate provides a Pregel-inspired graph execution runtime for agent workflows.
|
||||
|
||||
### Module Structure
|
||||
|
||||
```
|
||||
rust-research-agent/crates/rig-deepagents/src/
|
||||
├── lib.rs # Library entry point and re-exports

|
||||
├── llm/ # LLMProvider abstraction (OpenAI, Anthropic)
|
||||
└── tools/ # Tool implementations (read_file, write_file, grep, etc.)
|
||||
```
|
||||
|
||||
### Pregel Execution Model
|
||||
|
||||
The runtime executes workflows using synchronized supersteps:
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────────────────────────┐
|
||||
│ PregelRuntime │
|
||||
│ ┌─────────┐ ┌─────────┐ ┌─────────┐ │
|
||||
│ │Superstep│→ │Superstep│→ │Superstep│→ ... │
|
||||
│ │ 0 │ │ 1 │ │ 2 │ │
|
||||
│ └─────────┘ └─────────┘ └─────────┘ │
|
||||
│ │ │ │ │
|
||||
│ ▼ ▼ ▼ │
|
||||
│ Per-Superstep: Deliver → Compute → Collect → Route │
|
||||
└─────────────────────────────────────────────────────────────┘
|
||||
```
|
||||
|
||||
- **Vertex**: Computation unit with `compute()` method (Agent, Tool, Router)
|
||||
- **Message**: Communication between vertices across supersteps
|
||||
- **Checkpointing**: Fault tolerance via periodic state snapshots
|
||||
- **Retry Policy**: Exponential backoff with configurable max retries
|
||||
|
||||
### Key Types
|
||||
|
||||
| Type | Purpose |
|
||||
|------|---------|
|
||||
| `PregelRuntime<S, M>` | Executes workflow graph with state S and message M |
|
||||
| `Vertex<S, M>` | Trait for computation nodes |
|
||||
| `WorkflowState` | Trait for workflow state (must be serializable) |
|
||||
| `PregelConfig` | Runtime configuration (max supersteps, parallelism, timeout) |
|
||||
| `Checkpointer` | Trait for state persistence (Memory, File, SQLite, Redis, Postgres) |
|
||||

# Rig-DeepAgents Code Review 수정 계획
|
||||
|
||||
> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
|
||||
|
||||
**Goal:** Codex 및 Code Review에서 식별된 HIGH/MEDIUM 이슈를 수정하여 Python DeepAgents와의 패리티를 확보하고 프로덕션 준비 상태를 달성한다.
|
||||
|
||||
**Architecture:**
|
||||
- MemoryBackend와 AgentState.files의 이중 소스 문제는 `files_update` 반환 패턴을 통해 해결 (Python 패턴 유지)
|
||||
- 경로 처리는 중앙화된 `normalize_path` 유틸리티로 통일
|
||||
- CompositeBackend의 glob/write/edit 결과 집계 및 경로 복원 로직 보강
|
||||
|
||||
**Tech Stack:** Rust 1.75+, tokio, async-trait, glob crate
|
||||
|
||||
**검증 피드백 출처:**
|
||||
- Codex CLI (gpt-5.2-codex): 55,431 토큰 분석
|
||||
- Code Reviewer Subagent: 독립 검증
|
||||
|
||||
---
|
||||
|
||||
## Phase 1: HIGH Severity 수정 (필수)
|
||||
|
||||
### Task 1.1: MemoryBackend glob() base_path 필터 적용
|
||||
|
||||
**Files:**
|
||||
- Modify: `rust-research-agent/crates/rig-deepagents/src/backends/memory.rs:191-213`
|
||||
- Test: 동일 파일 하단 tests 모듈
|
||||
|
||||
**문제:** `glob()`이 `base_path`를 검증만 하고 실제 필터링에 사용하지 않아 모든 파일이 검색됨
|
||||
|
||||
**Step 1: 실패하는 테스트 작성**
|
||||
|
||||
`memory.rs` tests 모듈에 추가:
|
||||
|
||||
```rust
|
||||
#[tokio::test]
|
||||
async fn test_memory_backend_glob_respects_base_path() {
|
||||
let backend = MemoryBackend::new();
|
||||
backend.write("/src/main.rs", "fn main()").await.unwrap();
|
||||
backend.write("/src/lib.rs", "pub mod").await.unwrap();
|
||||
backend.write("/docs/readme.md", "# Readme").await.unwrap();
|
||||
backend.write("/tests/test.rs", "test code").await.unwrap();
|
||||
|
||||
// /src 하위에서만 검색해야 함
|
||||
let files = backend.glob("**/*.rs", "/src").await.unwrap();
|
||||
|
||||
// /src 하위의 .rs 파일만 포함되어야 함
|
||||
assert_eq!(files.len(), 2);
|
||||
assert!(files.iter().all(|f| f.path.starts_with("/src")));
|
||||
|
||||
// /tests/test.rs는 포함되면 안 됨
|
||||
assert!(!files.iter().any(|f| f.path.contains("/tests/")));
|
||||
}
|
||||
```
|
||||
|
||||
**Step 2: 테스트 실패 확인**
|
||||
|
||||
Run: `source ~/.cargo/env && cd rust-research-agent/crates/rig-deepagents && cargo test test_memory_backend_glob_respects_base_path`
|
||||
Expected: FAIL - 현재 구현은 모든 .rs 파일(4개)을 반환
|
||||
|
||||
**Step 3: glob() 구현 수정**
|
||||
|
||||
`memory.rs` 191-213 라인을 다음으로 교체:
|
||||
|
||||
```rust
|
||||
async fn glob(&self, pattern: &str, base_path: &str) -> Result<Vec<FileInfo>, BackendError> {
|
||||
let base = Self::validate_path(base_path)?;
|
||||
let files = self.files.read().await;
|
||||
|
||||
let glob_pattern = Pattern::new(pattern)
|
||||
.map_err(|e| BackendError::Pattern(e.to_string()))?;
|
||||
|
||||
let mut results = Vec::new();
|
||||
for (file_path, data) in files.iter() {
|
||||
// base_path 하위 파일만 검색
|
||||
let normalized_base = base.trim_end_matches('/');
|
||||
if !file_path.starts_with(normalized_base) {
|
||||
continue;
|
||||
}
|

### Task 1.2: CompositeBackend files_update 키 경로 복원
|
||||
|
||||
**Files:**
|
||||
- Modify: `rust-research-agent/crates/rig-deepagents/src/backends/composite.rs:107-133`
|
||||
- Test: 동일 파일 하단 tests 모듈
|
||||
|
||||
**문제:** routed backend에서 반환된 `files_update`의 키가 stripped 경로로 남아있어 상태 업데이트 시 경로 오류 발생
|
||||
|
||||
**Step 1: 실패하는 테스트 작성**
|
||||
|
||||
`composite.rs` tests 모듈에 추가:
|
||||
|
||||
```rust
|
||||
#[tokio::test]
|
||||
async fn test_composite_backend_write_files_update_path_restoration() {
|
||||
let default = Arc::new(MemoryBackend::new());
|
||||
let memories = Arc::new(MemoryBackend::new());
|
||||
|
||||
let composite = CompositeBackend::new(default.clone())
|
||||
.with_route("/memories/", memories.clone());
|
||||
|
||||
// routed backend에 파일 쓰기
|
||||
let result = composite.write("/memories/notes.txt", "my notes").await.unwrap();
|
||||
|
||||
assert!(result.is_ok());
|
||||
assert_eq!(result.path, Some("/memories/notes.txt".to_string()));
|
||||
|
||||
// files_update가 있다면 키도 복원되어야 함
|
||||
if let Some(files_update) = &result.files_update {
|
||||
// 키가 /memories/notes.txt 여야 함 (stripped된 /notes.txt가 아님)
|
||||
assert!(files_update.contains_key("/memories/notes.txt"),
|
||||
"files_update key should be '/memories/notes.txt', got keys: {:?}",
|
||||
files_update.keys().collect::<Vec<_>>());
|
||||
}
|

let memories = Arc::new(MemoryBackend::new());
|
||||
|
||||
let composite = CompositeBackend::new(default.clone())
|
||||
.with_route("/memories/", memories.clone());
|
||||
|
||||
// 먼저 파일 생성
|
||||
composite.write("/memories/notes.txt", "hello world").await.unwrap();
|
||||
|
||||
// 편집
|
||||
let result = composite.edit("/memories/notes.txt", "hello", "goodbye", false).await.unwrap();
|
||||
|

|
||||
files_update.keys().collect::<Vec<_>>());
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Step 2: 테스트 실패 확인**
|
||||
|
||||
Run: `source ~/.cargo/env && cd rust-research-agent/crates/rig-deepagents && cargo test test_composite_backend_write_files_update`
|
||||
Expected: FAIL - 키가 `/notes.txt`로 되어있음
|
||||
|
||||
**Step 3: write() 및 edit() 구현 수정**
|
||||
|
||||
`composite.rs`의 write() 메서드 (107-116 라인)를 다음으로 교체:
|
||||
|
||||
```rust
|
||||
async fn write(&self, path: &str, content: &str) -> Result<WriteResult, BackendError> {
|
||||
let (backend, stripped) = self.get_backend_and_path(path);
|
||||
let mut result = backend.write(&stripped, content).await?;
|
||||
|
||||
// 경로 복원
|
||||
if result.path.is_some() {
|
||||
result.path = Some(path.to_string());
|
||||
}
|
||||
|
||||
// files_update 키도 복원
|
||||
if let Some(ref mut files_update) = result.files_update {
|
||||
let restored: std::collections::HashMap<String, crate::state::FileData> = files_update
|
||||
.drain()
|
||||
.map(|(k, v)| (self.restore_prefix(&k, path), v))
|
||||
.collect();
|
||||
*files_update = restored;
|
||||
}
|
||||
|
||||
Ok(result)
|
||||
}
|
||||
```
|
||||
|
||||
`composite.rs`의 edit() 메서드 (118-133 라인)를 다음으로 교체:
|
||||
|
||||
```rust
|
||||
async fn edit(
|
||||
&self,
|
||||
path: &str,
|
||||
old_string: &str,
|
||||
new_string: &str,
|
||||
replace_all: bool
|
||||
) -> Result<EditResult, BackendError> {
|
||||
let (backend, stripped) = self.get_backend_and_path(path);
|
||||
let mut result = backend.edit(&stripped, old_string, new_string, replace_all).await?;
|
||||
|
||||
// 경로 복원
|
||||
if result.path.is_some() {
|
||||
result.path = Some(path.to_string());
|
||||
}
|
||||
|
||||
// files_update 키도 복원
|
||||
if let Some(ref mut files_update) = result.files_update {
|
||||
let restored: std::collections::HashMap<String, crate::state::FileData> = files_update
|
||||
.drain()
|
||||
.map(|(k, v)| (self.restore_prefix(&k, path), v))
|
||||
.collect();
|
||||
*files_update = restored;
|
||||
}
|
||||
|
||||
Ok(result)
|
||||
}
|
||||
```
|
||||
|
||||
**Step 4: 상단에 import 추가 확인**
|
||||
|
||||
`composite.rs` 상단에 `use crate::state::FileData;` 가 있는지 확인. 없으면 추가.
|
||||
|
||||
**Step 5: 테스트 통과 확인**
|
||||
|
||||
Run: `source ~/.cargo/env && cd rust-research-agent/crates/rig-deepagents && cargo test test_composite_backend`
|
||||
Expected: 모든 composite 테스트 PASS
|
||||

### Task 1.3: CompositeBackend glob() 집계 로직 추가
|
||||
|
||||
**Files:**
|
||||
- Modify: `rust-research-agent/crates/rig-deepagents/src/backends/composite.rs:135-144`
|
||||
- Test: 동일 파일 하단 tests 모듈
|
||||
|
||||
**문제:** glob()이 단일 백엔드만 쿼리하여 Python처럼 모든 백엔드 결과를 집계하지 않음
|
||||
|
||||
**Step 1: 실패하는 테스트 작성**
|
||||
|
||||
```rust
|
||||
#[tokio::test]
|
||||
async fn test_composite_backend_glob_aggregates_all_backends() {
|
||||
let default = Arc::new(MemoryBackend::new());
|
||||
let docs = Arc::new(MemoryBackend::new());
|
||||
|
||||
let composite = CompositeBackend::new(default.clone())
|
||||
.with_route("/docs/", docs.clone());
|
||||
|
||||
// 각 백엔드에 파일 생성
|
||||
composite.write("/src/main.rs", "fn main()").await.unwrap();
|
||||
composite.write("/docs/guide.md", "# Guide").await.unwrap();
|
||||
composite.write("/docs/api.md", "# API").await.unwrap();
|
||||
|
||||
// 루트에서 모든 .md 파일 검색 - 모든 백엔드에서 집계해야 함
|
||||
let files = composite.glob("**/*.md", "/").await.unwrap();
|
||||
|
||||
// docs 백엔드의 2개 파일이 모두 포함되어야 함
|
||||
assert_eq!(files.len(), 2, "Expected 2 .md files, got: {:?}", files);
|
||||
assert!(files.iter().any(|f| f.path.contains("guide.md")));
|
||||
assert!(files.iter().any(|f| f.path.contains("api.md")));
|
||||
}
|
||||
```
|
||||
|
||||
**Step 2: 테스트 실패 확인**
|
||||
|
||||
Run: `source ~/.cargo/env && cd rust-research-agent/crates/rig-deepagents && cargo test test_composite_backend_glob_aggregates`
|
||||
Expected: FAIL - 현재는 default 백엔드만 검색
|
||||
|
||||
**Step 3: glob() 구현 수정**
|
||||
|
||||
`composite.rs`의 glob() 메서드 (135-144 라인)를 다음으로 교체:
|
||||
|
||||
```rust
|
||||
async fn glob(&self, pattern: &str, base_path: &str) -> Result<Vec<FileInfo>, BackendError> {
|
||||
// 특정 라우트 경로인 경우 해당 백엔드만 검색
|
||||
for route in &self.routes {
|
||||
let route_prefix = route.prefix.trim_end_matches('/');
|
||||
if base_path.starts_with(route_prefix) &&
|
||||
(base_path.len() == route_prefix.len() || base_path[route_prefix.len()..].starts_with('/')) {
|
||||
let (backend, stripped) = self.get_backend_and_path(base_path);
|
||||
let mut results = backend.glob(pattern, &stripped).await?;
|
||||
|
||||
for info in &mut results {
|
||||
info.path = self.restore_prefix(&info.path, base_path);
|
||||
}
|
||||
return Ok(results);
|
||||
}
|
||||
}
|
||||
|
||||
// 루트 또는 라우트되지 않은 경로 - 모든 백엔드에서 집계
|
||||
let mut all_results = self.default.glob(pattern, base_path).await?;
|
||||
|
||||
for route in &self.routes {
|
||||
let mut route_results = route.backend.glob(pattern, "/").await?;
|
||||
for info in &mut route_results {
|
||||
let prefix = route.prefix.trim_end_matches('/');
|
||||
info.path = format!("{}{}", prefix, info.path);
|
||||
}
|
||||
all_results.extend(route_results);
|
||||
}
|
||||
|
||||
all_results.sort_by(|a, b| a.path.cmp(&b.path));
|
||||
Ok(all_results)
|
||||
}
|
||||
```
|
||||
|
||||
**Step 4: 테스트 통과 확인**
|
||||
|
||||
Run: `source ~/.cargo/env && cd rust-research-agent/crates/rig-deepagents && cargo test test_composite_backend_glob`
|
||||
Expected: PASS

### Task 1.4: AgentState.clone() extensions 경고 로그 추가
|
||||
|
||||
**Files:**
|
||||
- Modify: `rust-research-agent/crates/rig-deepagents/src/state.rs:169-180`
|
||||
- Modify: `rust-research-agent/crates/rig-deepagents/Cargo.toml` (tracing 의존성 확인)
|
||||
|
||||
**문제:** clone() 시 extensions가 빈 HashMap으로 초기화되어 미들웨어 상태 손실
|
||||
|
||||
**Step 1: 현재 Clone 구현 확인**
|
||||
|
||||
`state.rs`의 Clone 구현 확인:
|
||||
|
||||
```rust
|
||||
impl Clone for AgentState {
|
||||
fn clone(&self) -> Self {
|
||||
Self {
|
||||
messages: self.messages.clone(),
|
||||
todos: self.todos.clone(),
|
||||
files: self.files.clone(),
|
||||
structured_response: self.structured_response.clone(),
|
||||
extensions: HashMap::new(), // 데이터 손실!
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Step 2: tracing import 추가**
|
||||
|
||||
`state.rs` 상단에 추가:
|
||||
|
||||
```rust
|
||||
use tracing::warn;
|
||||
```
|
||||
|
||||
**Step 3: Clone 구현에 경고 로그 추가**
|
||||
|
||||
`state.rs`의 Clone 구현을 다음으로 교체:
|
||||
|
||||
```rust
|
||||
impl Clone for AgentState {
|
||||
fn clone(&self) -> Self {
|
||||
// extensions가 비어있지 않으면 경고
|
||||
if !self.extensions.is_empty() {
|
||||
warn!(
|
||||
extension_count = self.extensions.len(),
|
||||
extension_keys = ?self.extensions.keys().collect::<Vec<_>>(),
|
||||
"AgentState.clone() called with non-empty extensions - extensions will be lost"
|
||||
);
|
||||
}
|
||||
|
||||
Self {
|
||||
messages: self.messages.clone(),
|
||||
todos: self.todos.clone(),
|
||||
files: self.files.clone(),
|
||||
structured_response: self.structured_response.clone(),
|
||||
// extensions는 Box<dyn Any>를 clone할 수 없어서 빈 상태로 시작
|
||||
// 향후 Arc<RwLock<_>> 패턴으로 개선 고려
|
||||
extensions: HashMap::new(),
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Step 4: 컴파일 확인**
|
||||
|
||||
Run: `source ~/.cargo/env && cd rust-research-agent/crates/rig-deepagents && cargo check`
|
||||
Expected: 성공 (경고만 있을 수 있음)
|

|
||||
## Phase 2: MEDIUM Severity 수정
|
||||
|
||||
### Task 2.1: 경로 정규화 유틸리티 추가 및 적용
|
||||
|
||||
**Files:**
|
||||
- Create: `rust-research-agent/crates/rig-deepagents/src/backends/path_utils.rs`
|
||||
- Modify: `rust-research-agent/crates/rig-deepagents/src/backends/mod.rs`
|
||||
- Modify: `rust-research-agent/crates/rig-deepagents/src/backends/memory.rs`
|
||||
|

**Step 1: path_utils.rs 생성**
|
||||
|
||||
```rust

// src/backends/path_utils.rs
|
||||
//! 경로 정규화 유틸리티

```
|

**Step 2: mod.rs에 모듈 추가**
|
||||
|

`backends/mod.rs` 수정:
|
||||
|
||||
```rust
|
||||
// src/backends/mod.rs
|

//! 백엔드 모듈
|

//!
|

pub use composite::CompositeBackend;
|
||||
pub use path_utils::{normalize_path, is_under_path};
|
||||
```
|
||||
|
||||
**Step 3: MemoryBackend에서 path_utils 사용**
|
||||
|
||||
`memory.rs` 상단 import 추가:
|
||||
|
||||
```rust
|
||||
use super::path_utils::{normalize_path, is_under_path};
|
||||
```
|
||||
|
||||
`memory.rs`의 `validate_path` 함수를 제거하고 `normalize_path` 사용으로 교체:
|
||||
|

기존:
|
||||
```rust
|
||||
fn validate_path(path: &str) -> Result<String, BackendError> { ... }
|
||||
```
|
||||
|
||||
모든 `Self::validate_path(path)?` 호출을 `normalize_path(path)?`로 교체.
|
||||
|
||||
**Step 4: 테스트 실행**
|
||||
|
||||
Run: `source ~/.cargo/env && cd rust-research-agent/crates/rig-deepagents && cargo test path_utils`
|

**문제:** `/memories` 경로가 `/memories/` 라우트와 매칭되지 않음
|
||||
|
||||
**Step 1: 실패하는 테스트 작성**
|
||||
|
||||
```rust
|
||||
#[tokio::test]
|
||||
async fn test_composite_backend_route_matching_without_trailing_slash() {
|
||||
let default = Arc::new(MemoryBackend::new());
|
||||
let memories = Arc::new(MemoryBackend::new());
|
||||
|
||||
let composite = CompositeBackend::new(default.clone())
|
||||
.with_route("/memories/", memories.clone());
|
||||
|
||||
// 후행 슬래시 없이도 라우트되어야 함
|
||||
composite.write("/memories/notes.txt", "my notes").await.unwrap();
|
||||
|
||||
// /memories 경로로 읽기 (후행 슬래시 없음)
|
||||
let files = composite.ls("/memories").await.unwrap();
|
||||
assert!(!files.is_empty(), "Should find files under /memories route");
|
||||
}
|
||||
```
|
||||
|
||||
**Step 2: get_backend_and_path() 수정**
|
||||
|
||||
`composite.rs`의 `get_backend_and_path` 메서드를 다음으로 교체:
|
||||
|
||||
```rust
|
||||
/// 경로에 맞는 백엔드와 변환된 경로 반환
|
||||
fn get_backend_and_path(&self, path: &str) -> (Arc<dyn Backend>, String) {
|
||||
// 경로 정규화 (후행 슬래시 제거)
|
||||
let normalized_path = path.trim_end_matches('/');
|
||||
|
||||
for route in &self.routes {
|
||||
let route_prefix = route.prefix.trim_end_matches('/');
|
||||
|
||||
// 정확히 일치하거나 route_prefix/ 로 시작하는 경우
|
||||
if normalized_path == route_prefix ||
|
||||
normalized_path.starts_with(&format!("{}/", route_prefix)) {
|
||||
let suffix = if normalized_path == route_prefix {
|
||||
""
|
||||
} else {
|
||||
&normalized_path[route_prefix.len()..]
|
||||
};
|
||||
|
||||
let stripped = if suffix.is_empty() {
|
||||
"/".to_string()
|
||||
} else {
|
||||
suffix.to_string()
|
||||
};
|
||||
return (route.backend.clone(), stripped);
|
||||
}
|
||||
}
|
||||
(self.default.clone(), path.to_string())
|
||||
}
|
||||
```
|
||||
|
||||
**Step 3: 테스트 통과 확인**
|
||||
|
||||
Run: `source ~/.cargo/env && cd rust-research-agent/crates/rig-deepagents && cargo test test_composite_backend_route_matching`
|
||||
Expected: PASS

### Task 2.3: FilesystemBackend grep에서 tokio::fs 사용
|
||||
|
||||
**Files:**
|
||||
- Modify: `rust-research-agent/crates/rig-deepagents/src/backends/filesystem.rs:283-300`
|
||||
|
||||
**문제:** async 함수 내에서 sync `std::fs::read_to_string` 사용으로 런타임 블로킹
|
||||
|
||||
**Step 1: grep() 내부 파일 읽기를 async로 변경**
|
||||
|
||||
`filesystem.rs`의 grep 메서드에서 파일 읽기 부분을 수정.
|
||||
|
||||
기존:
|
||||
```rust
|
||||
let content = match std::fs::read_to_string(entry.path()) {
|
||||
Ok(c) => c,
|
||||
Err(_) => continue,
|
||||
};
|
||||
```
|
||||
|
||||
수정:
|
||||
```rust
|
||||
let content = match fs::read_to_string(entry.path()).await {
|
||||
Ok(c) => c,
|
||||
Err(e) => {
|
||||
tracing::debug!(path = ?entry.path(), error = %e, "Skipping file in grep due to read error");
|
||||
continue;
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
**Step 2: filesystem.rs 상단에 tracing import 추가**
|
||||
|
||||
```rust
|
||||
use tracing;
|
||||
```
|
||||
|
||||
**Step 3: 컴파일 확인**
|
||||
|
||||
Run: `source ~/.cargo/env && cd rust-research-agent/crates/rig-deepagents && cargo check`
|
||||
Expected: 성공
|
||||
|
||||
---
|
||||
|
||||
### Task 2.4: max_recursion 설정 가능하게 변경
|
||||
|
||||
**Files:**
|
||||
- Modify: `rust-research-agent/crates/rig-deepagents/src/runtime.rs:41-48`
|
||||
|
||||
**Step 1: RuntimeConfig::new()에 기본값을 Python과 동일하게 수정**
|
||||
|
||||
```rust
|
||||
impl RuntimeConfig {
|
||||
pub fn new() -> Self {
|
||||
Self {
|
||||
debug: false,
|
||||
max_recursion: 100, // Python 기본값에 가깝게 조정 (1000은 너무 높음)
|
||||
current_recursion: 0,
|
||||
}
|
||||
}
|
||||
|
||||
/// 커스텀 재귀 제한으로 생성
|
||||
pub fn with_max_recursion(max_recursion: usize) -> Self {
|
||||
Self {
|
||||
debug: false,
|
||||
max_recursion,
|
||||
current_recursion: 0,
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Step 2: 테스트 수정**
|
||||
|
||||
`runtime.rs`의 기존 테스트 `test_recursion_limit`를 수정:
|
||||
|
||||
```rust
|
||||
#[test]
|
||||
fn test_recursion_limit() {
|
||||
let state = AgentState::new();
|
||||
let backend = Arc::new(MemoryBackend::new());
|
||||
|
||||
// 커스텀 재귀 제한 사용
|
||||
let config = RuntimeConfig::with_max_recursion(10);
|
||||
let mut runtime = ToolRuntime::new(state, backend).with_config(config);
|
||||
|
||||
for _ in 0..10 {
|
||||
runtime = runtime.with_increased_recursion();
|
||||
}
|
||||
|
||||
assert!(runtime.is_recursion_limit_exceeded());
|
||||
}
|
||||
|
||||
#[test]
|
||||
fn test_default_recursion_limit() {
|
||||
let state = AgentState::new();
|
||||
let backend = Arc::new(MemoryBackend::new());
|
||||
let runtime = ToolRuntime::new(state, backend);
|
||||
|
||||
// 기본 제한은 100
|
||||
assert_eq!(runtime.config().max_recursion, 100);
|
||||
}
|
||||
```
|
||||
|
||||
**Step 3: 테스트 통과 확인**
|
||||
|
||||
Run: `source ~/.cargo/env && cd rust-research-agent/crates/rig-deepagents && cargo test runtime`
|
||||
Expected: PASS
|
||||
|
||||
---
|
||||
|
||||
## Phase 3: 최종 검증
|
||||
|
||||
### Task 3.1: 전체 테스트 실행 및 검증
|
||||
|
||||
**Step 1: 전체 테스트 실행**
|
||||
|
||||
Run: `source ~/.cargo/env && cd rust-research-agent/crates/rig-deepagents && cargo test`
|
||||
Expected: 모든 테스트 PASS (30개 이상)
|
||||
|
||||
**Step 2: Clippy 린트 확인**
|
||||
|
||||
Run: `source ~/.cargo/env && cd rust-research-agent/crates/rig-deepagents && cargo clippy -- -D warnings`
|
||||
Expected: 경고 없음 (또는 허용 가능한 경고만)
|
||||
|
||||
**Step 3: 문서 주석 확인**
|
||||
|
||||
Run: `source ~/.cargo/env && cd rust-research-agent/crates/rig-deepagents && cargo doc --no-deps`
|
||||
Expected: 문서 생성 성공
|
||||
|
||||
---
|
||||
|
||||
### Task 3.2: 변경사항 커밋
|
||||
|
||||
**Step 1: 변경 파일 확인**
|
||||
|
||||
Run: `git status`
|
||||
Expected: 수정된 Rust 파일들 표시
|
||||
|
||||
**Step 2: 커밋**
|
||||
|
||||
```bash
|
||||
git add rust-research-agent/crates/rig-deepagents/
|
||||
git commit -m "fix: address HIGH and MEDIUM severity issues from Codex/Code Review
|
||||
|
||||
HIGH fixes:
|
||||
- glob() now respects base_path filtering (security fix)
|
||||
- CompositeBackend write/edit restores files_update key paths
|
||||
- CompositeBackend glob aggregates results from all backends
|
||||
- AgentState.clone() logs warning when extensions lost
|
||||
|
||||
MEDIUM fixes:
|
||||
- Add centralized path_utils for consistent path normalization
|
||||
- CompositeBackend route matching normalizes trailing slashes
|
||||
- FilesystemBackend grep uses async tokio::fs
|
||||
- RuntimeConfig.max_recursion increased to 100 (was 10)
|
||||
|
||||
Verified by: Codex CLI (gpt-5.2-codex), Code Reviewer subagent"

//! Pregel Runtime for Graph-Based Agent Orchestration

//! Key concepts:

//!
|

//! - **Vertex**: Computation unit (Agent, Tool, Router, etc.)
|

//! - **Edge**: Connection between vertices (Direct, Conditional)
|
||||
//! - **Superstep**: Synchronized execution phase
|
||||
//! - **Message**: Communication between vertices
|
